  4 | 
  5 | ## 本文主要探讨TextView控件绘制文字,上下会留有一定空白原因.以及使用canvas.drawText()绘制文字时,baseLine的该如何确定,如何让文字上下没有留白
  6 | 
  7 | 最近做项目的时候遇到个问题
  8 | 
  9 | ![Image](/img/_001.png)
 10 | 
 11 | 当时的布局是这样的(一言不合就上图,具体代码请点击图片)
 12 | 
 13 | [![Image](/img/_002.png)](/app/src/main/res/layout/_001.xml)
 14 | 
 15 | 什么,这百分号和数字怎么对齐?这数字下面的文字怎么居中?这层级为什么这么复杂,关键外面还有好多层父布局,这是要上天呀!
 16 | 
 17 | ![Image](/img/_100.png)
 18 | 
 19 | ## 解决思路
 20 | 
 21 | 薄荷就是醒脑,表情包还没做完思路就出来.
 22 | 
 23 | * 减少层级,采用一个TextView
 24 | 
 25 | ```xml
 26 | <LinearLayout>
 27 |     <TextView/>
 28 |     <TextView/>
 29 |     <TextView/>
 30 | </LinearLayout>
 31 | ```
 32 | 
 33 | * 每个TextView的大小,用SpannableString控制其大小和颜色.理论上是很简单的,下面是具体的代码
 34 | 
 35 | [布局](/app/src/main/res/layout/_002.xml)
 36 | 
 37 | 代码:
 38 | 
 39 | ```java
 40 | TextView textView = (TextView) findViewById(R.id._001);
 41 |         String text = new String("60%/n主胜");
 42 |         spannableString = new SpannableString(text);
 43 |         int size = (int) TypedValue.applyDimension(TypedValue.COMPLEX_UNIT_SP, 12, getResources()
 44 |                 .getDisplayMetrics());
 45 |         spannableString.setSpan(new AbsoluteSizeSpan(size), 2, 3, Spanned
 46 |                 .SPAN_EXCLUSIVE_EXCLUSIVE);//设置字体大小
 47 |         spannableString.setSpan(new ForegroundColorSpan(Color.parseColor("#FF00FF")), 2, 3,
 48 |                 Spanned.SPAN_EXCLUSIVE_EXCLUSIVE);//设置字体颜色
 49 | 
 50 |         int size2 = (int) TypedValue.applyDimension(TypedValue.COMPLEX_UNIT_SP, 30, getResources
 51 |                 ().getDisplayMetrics());
 52 |         spannableString.setSpan(new AbsoluteSizeSpan(size2), text.length() - 2, text.length(),
 53 |                 Spanned.SPAN_EXCLUSIVE_EXCLUSIVE);//设置字体大小
 54 |         spannableString.setSpan(new ForegroundColorSpan(Color.parseColor("#000FFF")), text.length
 55 |                 () - 2, text.length(), Spanned.SPAN_EXCLUSIVE_EXCLUSIVE);//设置字体颜色
 56 |         textView.setText(spannableString);
 57 | ```
 58 | 
 59 | * 最终效果:
 60 | 
 61 | ![Image](/img/_003.png)
 62 | 
 63 | ![Image](/img/_101.png)
 64 | 
 65 | 实践与理论一样简单,完全不是个事.然后我就兴冲冲的把代码提交了.一切都很顺利,同事还夸我脑子灵活.
 66 | 
 67 | ### 当然故事肯定都没有这么简单的,这么简单也什么好写博客的,毕竟天天都有人夸我.
 68 | 
 69 | ## 事故
 70 | 说到事故,先说个故事.
 71 | 
 72 | APP都有个设计,视觉都会有个美女,自从调来了一个美女视觉之后我干活就有劲了,整天乐不思蜀....
 73 | 
 74 | ![Image](/img/_102.png)
 75 | 
 76 | 美女的脾气都不好,她说这个%号要靠上,不能靠下.
 77 | 
 78 | 我好说歹说,说实现起来不容易呀,如果靠上要用复杂的布局,会影响性能...
 79 | 
 80 | ### 不行,必须靠上!!!
 81 | 
 82 | 整个人都斯巴达了,关键是美女没法发脾气,这才是上层把她调过来的真实目的吗?
 83 | 
 84 | ### 百分号%下对齐的原因
 85 | 
 86 | 百分号之所以下对齐,是因为普通图形的绘制,是从图纸的左上角开始绘制的,而文字的绘制则是从左下角开始的.
 87 | 
 88 | 具体可以看一下canvas.draw图形方法,以及canvas.drawText方法参数.
 89 | 
 90 | 问题是知道的,但是没有办法和设计解释,然而也想出好的方法改变baseLine绘制.
 91 | Google一圈没有答案,群里问了一圈也没有,建议自己定义,看来只好自己动手了.
 92 | 
 93 | 
 94 | ## 思路
 95 | SpannableString基本上是可以满足需求的,关键是画%百分号的时候不满足.
 96 | 
 97 | * 看源码看TextView是如何利用SpannableString画的,覆写其关键代码达到目的
 98 | 
 99 |     源码老复杂了看不懂.看资料SpannableString有一个上标的功能,试了一下上标是相对于本身字体大小来上标的,而60与%相差甚远,且无法微调
100 | 
101 | * 画百分号%的时候自己画(看来只能这个思路了)
102 | 
103 | ### 自定义TextView
104 | * 自定义StyleTextView继承TextView
105 | * 定义类TextStyle
106 | 
107 | ```java
108 | public static class TextStyle {
109 |         String content;
110 |         int size;
111 |         int color;
112 |         boolean up = false;//是否上标
113 | 
114 |         public TextStyle() {
115 |         }
116 | 
117 |         public TextStyle(String content, int size, int color, boolean up) {
118 |             this.content = content;
119 |             this.size = size;
120 |             this.color = color;
121 |             this.up = up;
122 |         }
123 |     }
124 | ```
125 | 
126 | * 定义方法setText.
127 | ```java
128 |   /**
129 |      * 设置Text
130 |      * @param content String
131 |      * @param styles
132 |      */
133 |     public void setText(String content, TextStyle... styles) {
134 |         this.content = content;
135 |         spannableString = new SpannableString(content);
136 |         int i = 0;
137 |         for (TextStyle styleContent : styles) {
138 |             if (i == 0) first = styleContent;
139 |             else if (i == 1) second = styleContent;
140 |             i++;
141 |             int start = content.indexOf(styleContent.content);
142 |             int end = start + styleContent.content.length();
143 |             if (styleContent.size != -1)
144 |                 spannableString.setSpan(new AbsoluteSizeSpan(styleContent.size), start, end,
145 |                         Spanned.SPAN_EXCLUSIVE_EXCLUSIVE);
146 |             if (styleContent.color != -1)
147 |                 spannableString.setSpan(new ForegroundColorSpan(styleContent.color), start, end,
148 |                         Spanned.SPAN_EXCLUSIVE_EXCLUSIVE);
149 |             if (styleContent.up) {//上标时设置颜色为透明色,然后在onDraw自己画
150 |                 spannableString.setSpan(new ForegroundColorSpan(Color.TRANSPARENT), start, end,
151 |                         Spanned.SPAN_EXCLUSIVE_EXCLUSIVE);
152 |             }
153 |         }
154 |         setText(spannableString);
155 |     }
156 | ```
157 | 
158 | * 覆写onDraw方法
159 | 
160 | ```java
161 |  canvas.drawText(content, startX, baseLine, mPaint);
162 | ```
163 | 
164 | ### 到此自定义View完全结束.
165 | 
166 | ## 外传
167 | 
168 | 故事到这里就结束肯定不叫故事.
169 | 
170 | 上面所有的都并非关键,关键是drawText()参数.
171 | 
172 | 之前说了,drawText是从左下角开始画的,所以要计算出startX与baseLine的值.
173 | 
174 | startX:计算出百分号之前的"60"的宽度即可.
175 | 
176 | baseLine:baseLine默认是等于-top(后文证明),但TextView上下有一定的空白,导致直接写-top不满足需求
177 | 
178 | ![Image](/img/_012.png)
179 | 
180 | 图片来源于网络
181 | 
182 | 当文字字号过大时,空白非常的明显.设计要求"60%"百分号与60对齐,所以必须量出空白的高度.
183 | 
184 | ### 测试上图中的各个属性
185 | 
186 | 按照上图的说法,我们打印一下这几个值
187 | 
188 | ```xml
189 |   <TextView
190 |         android:id="@+id/_test"
191 |         android:layout_width="wrap_content"
192 |         android:layout_height="wrap_content"
193 |         android:text="Hello !"
194 |         android:textSize="60sp"/>
195 | ```
196 | ```java
197 |  final TextView textView2 = (TextView) findViewById(R.id._test);
198 |         textView2.setOnClickListener(new View.OnClickListener() {
199 |             @Override
200 |             public void onClick(View v) {
201 |                 Paint mPaint = textView2.getPaint();
202 |                 Log.e("siyehua", "top: " + mPaint.getFontMetrics().top + "  ascent: " + mPaint
203 |                         .getFontMetrics().ascent + "  descent: " + mPaint.getFontMetrics()
204 |                         .descent + "  " + "bottom: " + mPaint.getFontMetrics().bottom + "  " +
205 |                         "leading: " + mPaint.getFontMetrics().leading + "  /nview-top: " +
206 |                         textView2.getTop() + "  view-bottom: " + textView2.getBottom() + " " +
207 |                         "textSize: " + textView2.getTextSize());
208 |             }
209 |         });
210 | ```
211 | 
212 | 结果如下:(单位px,后文无特殊说明,单位均默认为像素px)
213 | ```
214 | top: -126.73828  ascent: -111.328125  descent: 29.296875  bottom: 32.51953  leading: 0.0
215 | view-top: 0  view-bottom: 160 textSize: 120.0
216 | ```
217 | 
218 | ![Image](/img/_013.png)
219 | 
220 | ### 其中top与ascent是负数,是因为baseline是0.
221 | 
222 | ### 根据上图,默认状态下,top与ascent在baseline上面,而安卓手机的Y轴正方向是向下的,故top与ascent是负数,所以前面提到的baseline实际上就等于-top.
223 | 
224 | 按照网上的说法,TextView的高度实际上是 top与 bottom的距离,与结果一致
225 | 
226 | 文字的高度是 ascent与descent之间的距离 111.328125 + 29.296875 ≈ 140.63px,而打印出来的文字的实际大小是120px,这个结果与预期不符.
227 | 
228 | * 假设ascent与descent是动态变化的,可能是"Hello !"这个字符串并没有达到ascent的最小值.
229 | 
230 | 我们知道 a 与 b 两个字符绘制的结果,b明显要冒出一个头.所以有可能是某些字符会突破天际,达到ascent与descent值
231 | 
232 | Google一圈没有发现到底用什么字符测试测试到上限值,但是不妨换一个思考方式,既然无法得到上限,可以突破下限.把TextView的字符串改为ac,看ascent与descent变化了没有.
233 | 
234 | ![Image](/img/_103.png)
235 | 
236 | * 可见ascent与descent不是动态变化的,知乎里看过有人提到,TextView上下有留白,是因为默认添加了一个上下的留白.
237 | 
238 | TextView本身包含一定的FontPadding.看TextView的setIncludeFontPadding()方法.一言不合上代码
239 | 
240 | ```java
241 |  /**
242 |      * Set whether the TextView includes extra top and bottom padding to make
243 |      * room for accents that go above the normal ascent and descent.
244 |      * The default is true.
245 |      *
246 |      * @see #getIncludeFontPadding()
247 |      *
248 |      * @attr ref android.R.styleable#TextView_includeFontPadding
249 |      */
250 |     public void setIncludeFontPadding(boolean includepad) {
251 |         if (mIncludePad != includepad) {
252 |             mIncludePad = includepad;
253 | 
254 |             if (mLayout != null) {
255 |                 nullLayouts();
256 |                 requestLayout();
257 |                 invalidate();
258 |             }
259 |         }
260 |     }
261 | ```
262 | 
263 | 源码不重要,关键是注释,注释里写默认是有一定的间距的,view的高度是top与bottom之间的间距,而设置为false之后,view的高度是ascent与descent之间的间距
264 | 重新设置并打印值
265 | 
266 | ```xml
267 | <TextView
268 |         android:id="@+id/_test"
269 |         android:layout_width="wrap_content"
270 |         android:layout_height="wrap_content"
271 |         android:includeFontPadding="false"
272 |         android:text="Hello !"
273 |         android:textSize="60sp"/>
274 | ```
275 | 
276 | 结果view的高度等于ascent与descent之间的高度.
277 | 
278 | ```
279 | top: -126.73828  ascent: -111.328125  descent: 29.296875  bottom: 32.51953  leading: 0.0
280 | view-top: 0  view-bottom: 140 textSize: 120.0
281 | ```
282 | 
283 | 结果符合源码的解释,同时完善一下上面的关于baseline的结论.
284 | 
285 | ### 假设设置了android:includeFontPadding="false",则baseline实际的值等于-ascent
286 | 
287 | 但是,并没有得到:
288 | 
289 | ```
290 | ascent与descent之间的距离等于textSize的大小.
291 | ```
292 | 
293 | 这个结论.
294 | 
295 | 那会不会是textSize的大小实际上指的并不是文字的高度,可能只是一个需要转换的值.
296 | 
297 | ![Image](/img/_104.png)
298 | 
299 | 截屏后使用Mark Man一量,这文字的高度妥妥的就是120px.换个说法就是
300 | 
301 | ```
302 | ascent与descent之间的距离不等于textSize的大小/高度.
303 | ```
304 | 
305 | ## 分析
306 | 
307 | ![Image](/img/_012.png)
308 | 
309 | 假设top与ascent之间的空白是firstSpace,ascent 与文字顶端的空白是secondSpace,
310 | 
311 | ```
312 | 则文字最顶端的Y坐标topTextY = firstSpace + secondSpace;(如TextView已经设置了android:includeFontPadding="false"则不需要加上firstSpace)
313 | firstSpace = ascent - top;
314 | secondSpace = descent - ascent - textSize;
315 | ```
316 | 
317 | 按照这个理论,画一条线.
318 | ```java
319 |     @Override
320 |     protected void onDraw(Canvas canvas) {
321 |         super.onDraw(canvas);
322 |         Paint mPaint = getPaint();
323 |         float lineY = mPaint.getFontMetrics().ascent - mPaint.getFontMetrics().top + mPaint
324 |                 .getFontMetrics().descent - mPaint.getFontMetrics().ascent - mPaint.getTextSize();
325 |         mPaint.setColor(Color.parseColor("#FF00FF"));
326 |         canvas.drawLine(0, lineY, getWidth(), lineY, mPaint);
327 |     }
328 | ```
329 | 
330 | ![Image](/img/_005.png)
331 | 
332 | 非常标准,刚好对齐,深得我意.
333 | 
334 | 所以画百分号的baseline等于
335 | 
336 | ```
337 | baseLine = topTextY + -top(默认状态下,百分号的baseline) - 百分号的topTextY;
338 | ```
339 | 
340 | 代码(详情请看自定义的[StyleTextView](/app/src/main/java/com/siyehua/styletextview/StyleTextView.java))
341 | 
342 | ```java
343 |  Paint mPaint = getPaint();
344 |             mPaint.setTextSize(first.size);
345 |             float startX = mPaint.measureText(first.content);
346 |             float space = topSpace(mPaint);
347 |             
348 |             //画顶部基准线
349 |             float lineY = mPaint.getFontMetrics().ascent - mPaint.getFontMetrics().top + mPaint
350 |                     .getFontMetrics().descent - mPaint.getFontMetrics().ascent - mPaint
351 |                     .getTextSize();
352 |             mPaint.setColor(Color.parseColor("#FF00FF"));
353 |             canvas.drawLine(0, lineY, getWidth(), lineY, mPaint);
354 | 
355 |             //画百分号
356 |             mPaint.setTextSize(second.size);
357 |             float baseLine = space + -mPaint.getFontMetrics().top - topSpace(mPaint);
358 |             mPaint.setColor(second.color);
359 |             canvas.drawText(second.content, startX, baseLine, mPaint);
360 | ```
361 | 
362 | 结果(60这个字符串本身距离直线有一点间距是因为字不够长,假设使用字母 'l' 刚刚好)
363 | 
364 | ![Image](/img/_006.png)
365 | 
366 | ### 总结
367 | 
368 | 终于要完了吗?实际上还没有
369 | 
370 | ![Image](/img/_105.png)
371 | 
372 | 假设TextView的宽度是match_parent,让内容居中
373 | 
374 | ```xml
375 | <com.siyehua.styletextview.StyleTextView
376 |         android:id="@+id/tv_content"
377 |         android:layout_width="match_parent"
378 |         android:layout_height="wrap_content"
379 |         android:gravity="center"
380 |         android:text="Hello !"
381 |         android:textSize="60sp"/>
382 | ```
383 | 
384 | ![Image](/img/_007.png)
385 | 
386 | 会发现百分号并没有跟着跑,实际上是因为canvas.drawText()这个方法的参数,startX与BaseLine还受内容的对齐方式影响
387 | 
388 | 而我绘制百分号并没有考虑这方面的因素.
389 | 
390 | 假设TextView的对齐方式是居中,则startX是TextView文字的中点.
391 | 
392 | ![Image](/img/_008.png)
393 | 
394 | 图中红框的右边便是文字的右边,而我们需要计算文字右边减去粉色百分号%,得到到即是上标百分号%的startY
395 | 
396 | ```
397 | 上标startY = 文字右边 - "%"宽度
398 | 文字右边距 = TextView宽度/2.0f + 需要绘制的文字的宽度/2.0f
399 | 需要绘制的文字的宽度 =  "60"串的宽度 + "%"百分号的宽度
400 | ```
401 | 
402 | ```java
403 | startX = getWidth() / 2.0f + (startX + mPaint.measureText(second.content)) / 2.0f -
404 |                     mPaint.measureText(second.content) * 1.5f;
405 | ```
406 | 
407 | 
408 | 
409 | 结果
410 | 
411 | ![Image](/img/_009.png)
412 | 
413 | 可以看到百分号的已经设置到了正确的位置.
414 | 
415 | 同理可得(其实我懒得算了)
416 | 
417 | #### 当TextView的高度设置match_parent,且内容设置居中时,需要用同样的方法计算baseline.
418 | 
419 | 这里就不在举例了.毕竟制作表情包太累了.
