It uses [jqMath](https://mathscribe.com/author/jqmath.html) to render math equations. 6 | 7 | ## Setup 8 | 9 | Add it in your **root** build.gradle at the end of repositories: 10 | 11 | ```groovy 12 | allprojects { 13 | repositories { 14 | ... 15 | maven { url 'https://jitpack.io' } 16 | } 17 | } 18 | ``` 19 | 20 | Add `implementation 'com.github.frhnfrq:MathView:1.2'` into **dependencies** section of your **module** build.gradle file. For example: 21 | 22 | ```groovy 23 | dependencies { 24 | implementation 'com.github.frhnfrq:MathView:1.2' 25 | } 26 | ``` 27 | ## Usage 28 | 29 | #### Add `MathView` in your layout 30 | 31 | ```xml 32 | 36 | ``` 37 | 38 | #### Get an instance of it in your code 39 | ```java 40 | MathView mathview = findViewById(R.id.mathview); 41 | mathview.setText("If $ax^2+bx+c=0$ with $a≠0$, then: $$x={-b±√{b^2-4ac}}/{2a}$$"); 42 | mathview.setPixelScaleType(Scale.SCALE_DP); 43 | mathview.setTextSize(16); 44 | mathview.setTextColor("#111111"); 45 | ``` 46 | 47 | ## Screenshot 48 | 49 | 50 | ## How to 51 | 52 | To learn how to write math equations in it, please have a look at [jqMath](https://mathscribe.com/author/jqmath.html). 53 | 54 | ## Advantages 55 | 56 | 1. Faster than MathJax. 57 | 2. Change text size and color easily. 58 | 3. Supports HTML outside of the equation. Example 59 | ```java 60 | mathview.setText("This is a straight line, $\ax + \by = \c$"); 61 | ``` 62 | 63 | 64 | ## Disadvantages 65 | 66 | 1. Special symbols are typed manually. Example: √ ∑ ∫ ← → + > 67 | 2. Some parts of the MathML standard are not yet implemented in jqMath, such as elementary school mathematics (e.g. “long division”), and “Content MathML.” 68 | 69 | 70 | 71 | 72 | License 73 | ======= 74 | 75 | Copyright 2018 Farhan Farooqui 76 | 77 | Licensed under the Apache License, Version 2.0 (the "License"); 78 | you may not use this file except in compliance with the License. 79 | You may obtain a copy of the License at 80 | 81 | http://www.apache.org/licenses/LICENSE-2.0 82 | 83 | Unless required by applicable law or agreed to in writing, software 84 | distributed under the License is distributed on an "AS IS" BASIS, 85 | WITHOUT WARRANTIES OR CONDITIONS OF ANY KIND, either express or implied. 86 | See the License for the specific language governing permissions and 87 | limitations under the License. 88 | -------------------------------------------------------------------------------- /gradlew: -------------------------------------------------------------------------------- 1 | #!/usr/bin/env sh 2 | 3 | ############################################################################## 4 | ## 5 | ## Gradle start up script for UN*X 6 | ## 7 | ############################################################################## 8 | 9 | # Attempt to set APP_HOME 10 | # Resolve links: $0 may be a link 11 | PRG="$0" 12 | # Need this for relative symlinks. 13 | while [ -h "$PRG" ] ; do 14 | ls=`ls -ld "$PRG"` 15 | link=`expr "$ls" : '.*-> \(.*\)$'` 16 | if expr "$link" : '/.*' > /dev/null; then 17 | PRG="$link" 18 | else 19 | PRG=`dirname "$PRG"`"/$link" 20 | fi 21 | done 22 | SAVED="`pwd`" 23 | cd "`dirname \"$PRG\"`/" >/dev/null 24 | APP_HOME="`pwd -P`" 25 | cd "$SAVED" >/dev/null 26 | 27 | APP_NAME="Gradle" 28 | APP_BASE_NAME=`basename "$0"` 29 | 30 | # Add default JVM options here.

(see below). 16 | 17 | F(s, x): Returns the method of x with name s. 18 | 19 | Example: If a is an array, F('concat', a) is a function which returns an array consisting of 20 | a followed by its arguments; F('push', a) is a function with the side-effect of appending 21 | its arguments to a. 22 | 23 | F(n, f): Equivalent to F.aritize(n, f) (see below). 24 | 25 | F(a, f): Equivalent to F.partial(a, f) (see below). 26 | 27 | F(p): Equivalent to F.pToF(p). (see below) 28 | 29 | F(x): If x is an HTML element, returns the jQuery data associated to that element. 30 | In all other cases (not covered above), equivalent to F.aToF(x). (see below) 31 | 32 | F.id(x): Identity function; returns x. 33 | 34 | F.constant(x): Builds a constant function; returns the function whose value is constantly x. 35 | 36 | F.applyF(f, a): Evaluates f using the elements of a as arguments. 37 | 38 | Example: F.applyF(f, [x, y, z]) is equivalent to f(x, y, z). 39 | 40 | F.curry(f, ...): Returns the function given by partially evaluating f on the remaining 41 | arguments. 42 | 43 | Example: g = F.curry(f, x) is a function with g(y, z, ...) = f(x, y, z, ...). 44 | 45 | F.partial(a, f): Returns the function given by partially evaluating f on the elements of a. 46 | 47 | Example: g = F.partial([x, y], f) is a function with g(z, ...) = f(x, y, z, ...). 48 | 49 | If any of the elements of a is F._, the function returned will "fill in" the corresponding 50 | argument in f before moving on to further-right arguments. 51 | 52 | Example: g = F.partial([x, F._, y], f) is a function with g(z, ...) = f(x, z, y, ...). 53 | 54 | F.uncurry(f): f should be a one-argument function that returns another one-argument function. 55 | Then g = F.uncurry(f) is a function with g(x, y) = f(x)(y). 56 | 57 | F.o(f, g, h, ...): Returns the function composition f o g o h o ... 58 | 59 | Example: F.o(f, g, h)(x) = f(g(h(x))). 60 | 61 | F.oMap(f, g): returns a function which evaluates g on each of its arguments, then uses them as 62 | an argument list for f. 63 | 64 | Example: If g is a one-argument function, h = F.oMap(f, g) is a function with 65 | h(x, y, z, ...) = f(g(x), g(y), g(z), ...) 66 | 67 | F.oMap() passes the index of each argument as a second argument to g. 68 | 69 | Example: If g is a two-argument function, h = F.oMap(f, g) is a function 70 | with h(x, y, z, ...) = f(g(x, 0), g(y, 1), g(z, 2), ...) 71 | 72 | As a third argument to g, F.oMap() passes its full Argument object. 73 | 74 | Example: If g is a function with at least 3 arguments, h = F.oMap(f, g) is a function with 75 | h(x, y, z) = f(g(x, 0, [x, y, z, ...]), g(y, 0, [x, y, z, ...]), g(z, 0, [x, y, z]), ...), 76 | except that the "arrays" are actually all array-like Argument objects. 77 | 78 | F.flip(f): f should be a two-argument function. F.flip(f) is the two argument function which 79 | is identical to f but with the arguments reversed: F.flip(f)(x, y) = f(y, x). 80 | 81 | F.seqF(f, g, h, ...): The arguments should be functions with side-effects. F.seqF returns a 82 | function which calls each of f, g, h, ... in turn, using its arguments as the arguments of each 83 | of them. 84 | 85 | Example: If h = F.seqF(f, g), then calling h(x, y, z, ...) is equivalent to calling 86 | f(x, y, z, ...) and then calling g(x, y, z, ...). 87 | 88 | F.cor(f, g, h, ...): The arguments should be functions. F.cor returns a function which calls 89 | each of f, g, h until one returns a truthy value, and then returns that value. 90 | 91 | Example: F.cor(F.eqTo(0), F.eqTo(1), F.eqTo(2)) returns a boolean-valued function which 92 | returns true iff x is either 0, 1, or 2. (see below for F.eqTo) 93 | 94 | F.aritize(n, f): Returns a function that is equivalent to f except that it ignores any arguments 95 | past the first n. 96 | 97 | Example: If g = F.aritize(2, f), then g(x, y) and g(x, y, z) are both equivalent to f(x, y). 98 | 99 | F.not(x): Returns ! x. 100 | 101 | F.defOr(x, y): Returns x if x !== undefined, else y. Beware: y is evaluated in either case. 102 | 103 | F.cmpX(x, y): Comparison for numbers or Dates; returns x - y (so negative if x < y, positive if 104 | x > y, 0 if x == y). 105 | 106 | F.cmpJS(x, y): Default JavaScript comparison for numbers, Dates, or strings; returns -1 107 | if x < y, 1 if x > 1, 0 otherwise. 108 | 109 | F.cmpLex(f, a, b) -- Compares a and b using "lexicographic order"; returns the first 110 | f(a[i], b[i]) which is truthy, or if none then just compares their lengths. 111 | 112 | F.eqTo(x): Returns a function of one argument that checks whether x is equal (===) to that 113 | argument. 114 | 115 | Example: If g = F.eqTo(5), g(x) returns true when x === 5 and false otherwise. 116 | 117 | F.eqTo(x, f): As above, but f is a comparison function (such as the three above). The function 118 | returned by F.eqTo will use f to check whether its argument is equal to x or not. 119 | 120 | Example: If g = F.eqTo(5, f) and f returns a number, then g(x) returns true when 121 | f(5, x) == 0 and false otherwise. 122 | 123 | F.pToF(p): Converts a property name or subscript to a function; returns the function that looks 124 | at its argument and returns the value indexed by p. 125 | 126 | Example: F.pToF(0) is a one-argument function that picks out the zeroth element in arrays. 127 | F.pToF('baseHeightA') is a one-argument function that picks out the value of the baseHeightA 128 | property in objects. 129 | 130 | F.aToF(a): "array to function": Returns the function f with f(i) = a[i]. (Despite the suggestive 131 | name, works on arbitrary objects.) 132 | 133 | Example: f = F.aToF([0, 1, 1]) is a function with f(0) = 0, f(1) = f(2) = 1, and f(x) 134 | undefined for any other x. 135 | 136 | g = F.aToF({ x: 1, y: 'fnord' }) is a function with g('x') = 1, g('y') = 'fnord', and g(z) 137 | undefined for any other z. 138 | 139 | F.fToA(f, n): "function to array": Returns an n-element array a with a[i] = f(i). 140 | 141 | F.memoF(f, x): returns a memoized version of f, storing all previously computed values of f in 142 | x. Can be called as a one-argument function in which case x will be automatically created and 143 | inaccessible. 144 | 145 | F.replicate(n, x): Returns an array whose n elements are all x. 146 | 147 | F.setF(x, p, y): A function whose side-effect is to set x[p] = y. Good for feeding to F to build 148 | other functions. 149 | 150 | F.obj1(p, x): Returns an object whose sole property p has value x. 151 | 152 | F.slice(a): Returns an array which is a shallow copy of the array-like object a. 153 | 154 | F.slice(a, n): Returns an array consisting of all the elements of a starting with a[n] if n is 155 | non-negative, or the element -n from the end if n is negative. Analogous to the array method of 156 | the same name, but also works on array-like objects. 157 | 158 | F.slice(a, n, m): Returns an array consisting of the elements of a starting with a[n] and 159 | going up to but not including a[m]; treats negative arguments modulo a.length as the 160 | two-argument version does. Can be called with n == null to start from the beginning of the 161 | array, like n == 0. 162 | 163 | F.array(x, y, z, ...): Returns its arguments in an array (not an array-like Argument object). 164 | 165 | Example: F.array(x, y, z, ...) returns [x, y, z, ...]. 166 | 167 | F.concatArgs(a, b, c, ...): Returns an array consisting of the elements of the array-like 168 | objects a, b, c, .... 169 | 170 | Example: F.concatArgs([x, y], [1, 2], [z]) returns [x, y, 1, 2, z]. 171 | 172 | F.concatMap(f, a): f should be a function that returns an array-like object. Returns an array 173 | obtained by applying f to each element of a in turn and then concatenating the resulting arrays. 174 | 175 | Example: If f(n) returns [n^2, 2n, 1], F.concatMap(f, [0, 1, 5, 100]) returns 176 | [0, 0, 1, 1, 2, 1, 25, 10, 1, 10000, 200, 1]. 177 | 178 | F.reverseCopy(a): Returns an array which is the reverse of a shallow copy of the array-like 179 | object a. 180 | 181 | F.findIndex(f, a): Returns the smallest i where f(a[i]) is truthy. If f has a second argument, 182 | it is taken to be the index i; a third argument is taken to be the entire array a. If no such i 183 | exists, returns -1. 184 | 185 | Example: F.findIndex(function(x) { return x == 3; }, [0, 1, 2, 3, 4, 3]) returns 3. 186 | F.findIndex(function(x) { return x == 3; }, [0, 1, 2]) returns -1. 187 | 188 | F.findLastIndex(f, a): As findIndex, except that it returns the largest i where f(a[i]) is 189 | truthy. 190 | 191 | Example: F.findLastIndex(function(x) { return x == 3; }, [0, 1, 2, 3, 4, 3]) returns 5. 192 | 193 | F.find(f, a): Returns the first a[i] with f(a[i]) truthy, or undefined if there is no such a[i]. 194 | 195 | Example: F.find(function(x) { return x > 3; }, [0, 4, 2]) returns 4. 196 | 197 | F.elemIndex(x, a, f): Returns the smallest i where a[i] == x, using f as a comparison function 198 | for equality if given (i.e., it finds i where f(x, a[i]) is falsy). 199 | 200 | F.elemLastIndex(x, a, f): As F.elemIndex, except that it returns the largest such i. 201 | 202 | F.elem(x, a, f): Returns true if x can be found in a and false otherwise, using f as a 203 | comparison function if given. 204 | 205 | F.all(f, a): Returns true if f(a[i], i, a) returns a truthy value for all i, and false 206 | otherwise. 207 | 208 | F.any(f, a): Returns the smallest-index f(a[i], i, a) which is truthy, or the last such value if 209 | none are truthy, or false if a is empty. 210 | 211 | F.iter(f, a, b, c, ...): f should be a function with side-effects. Calls f with arguments 212 | a[0], b[0], c[0], ...; then with arguments a[1], b[1], c[1], ...; and so on. If the arrays 213 | differ in length, ignores all remaining elements in longer arrays once the shortest array has 214 | run out. If f wants more arguments than there are arrays, the first additional argument is the 215 | index and each subsequent additional argument is an entire array a, b, c, ... . 216 | 217 | Example: F.iter(f, [x0, x1, x2], [y0, y1, y2]) is equivalent to calling: 218 | f(x0, y0); f(x1, y1); f(x2; y2); if f is a function of at most 2 arguments 219 | f(x0, y0, 0); f(x1, y1, 1); f(x2, y2, 2); if f is a function of 3 arguments 220 | f(x0, y0, 0, [x0, x1, x2], [y0, y1, y2]); ... in general. 221 | 222 | F.map(f, a): Returns the array whose ith element is f(a[i], i, a). 223 | 224 | F.map1(f, a): Returns the array whose ith element is f(a[i]) (even if f is capable of being 225 | passed more than one argument). 226 | 227 | F.zipWith(f, a, b, c, ...): Returns the array whose ith element is f(a[i], b[i], c[i], ...). If 228 | a, b, c, ... are not all the same length, ignores remaining elements in the longer ones once the 229 | shortest one has run out. 230 | 231 | F.zip(a, b, c, ...): Returns the array [[a[0], b[0], c[0], ...], [a[1], b[1], c[1], ...], ...]. 232 | 233 | F.unzip(a): a should be a *matrix* -- an array of arrays, where each row array has the same 234 | length (or elements beyond the shortest length are ignored). Returns the matrix transpose of a. 235 | 236 | Example: F.unzip([[1,2,3], [4,5,6], [7,8,9]]) returns [[1,4,7], [2,5,8], [3,6,9]]. 237 | 238 | F.filter(f, a): returns an array consisting of all those a[i] where f(a[i], i, a) is truthy, in 239 | their original order. 240 | 241 | Example: F.filter(eqTo(4), [1,2,3,4,5,4]) returns [4,4]. 242 | F.filter(F.not, [0, 1, null, 2, undefined, 3]) returns [0, null, undefined]. 243 | 244 | F.fold(f, a, x): Calls f(x, a[0]), then calls f on the result and a[1], and so on until the 245 | array is exhausted, and returns the result. If x is omitted, start the process with 246 | f(a[0], a[1]). Equivalent to the reduce method for genuine arrays. Also passes i and a to f. 247 | 248 | Example: If plus is a function that returns x + y, F.fold(plus, [0, 1, 2], ' ') returns the 249 | string ' 012'. 250 | 251 | F.foldR(f, a, x): The same as to F.fold except that it begins at the end of a (so it starts by 252 | calling f(x, a[a.length - 1])). Equivalent to the reduceRight method for genuine arrays. 253 | 254 | Example: If plus is a function that returns x + y, F.foldR(plus, [0, 1, 2], ' ') returns the 255 | string ' 210'. 256 | 257 | F.sum(a): Returns the sum of the elements of a. 258 | 259 | F.test(x): Returns a boolean function of one argument which checks that argument in some way 260 | determined by x -- usually some form of type-checking. 261 | 262 | To check whether: 263 | Something is a number Use F.test(0) (or F.test('number') -- see below) 264 | Something is a string Use F.test('') (or F.test('string') -- see below) 265 | Something has a type readable Use F.test(s) where s is a string returnable by the typeof 266 | by the typeof operator operator. 267 | (undefined, object, boolean, 268 | number, string, function) 269 | Something is an array, Date Use F.test(Array), F.test(Date), and F.test(RegExp) 270 | object, or Javascript regular respectively. 271 | expression, constructed in 272 | the same window frame 273 | Something is null Use F.test(null) 274 | 275 | If r is a regular expression, F.test(r) is equivalent to r.test (it returns true if its argument 276 | contains a match for r). 277 | 278 | If f is a function, F.test(f) returns f (allowing you to feed arbitrary test functions into the 279 | following recursive cases). 280 | 281 | F.test([x]) checks to see if its argument is an array, all of whose elements satisfy F.test(x). 282 | 283 | For arrays of more than one element, F.test(a) checks to see if its argument satisfies 284 | F.test(a[i]) for any i. 285 | 286 | For generic objects that don’t match any of the above, F.test(x) looks at some other object y 287 | and returns true if: 288 | -y is non-null, and 289 | -for every property p of x, y[p] passes the test F.test(x[p]). 290 | 291 | F.translations_: An object mapping user visible strings to their translations in the current 292 | language. 293 | 294 | F.s(s): Returns the translation of s if one exists, else s. 295 | -------------------------------------------------------------------------------- /mathview/src/main/assets/mathscribe/jqmath-etc-0.4.6.min.js: -------------------------------------------------------------------------------- 1 | /* Copyright 2016, Mathscribe, Inc.

Normally 9 | standard characters and fonts suffice, but "private use" character numbers and custom fonts 10 | can be used when necessary. By default, this module currently uses standard MathML 3 11 | precedences for operator symbols, except we omit "multiple character operator"s like && or 12 | <=, and choose a single precedence for each of |, ^, and _. 13 | 14 | The algorithm to detect MathML only works after some document.body is defined and available. 15 | Thus it should probably not be used during document loading. 16 | 17 | See http://mathscribe.com/author/jqmath.html for usage documentation and examples, and 18 | jscurry.js for some coding conventions and goals. */ 19 | 20 | /* Copyright 2017, Mathscribe, Inc.
