3 | # Drawing App Library
4 | Simple android library for drawing
5 |
6 | 
7 |
8 | # Setup
9 | ## 1. Provide the gradle dependency
10 |
11 | Add it in your root build.gradle at the end of repositories:
12 | ```
13 | allprojects {
14 | repositories {
15 | ...
16 | maven { url 'https://jitpack.io' }
17 | }
18 | }
19 | ```
20 |
21 | Add the gradle dependency to your `app` module `build.gradle` file:
22 |
23 | ```
24 | dependencies {
25 | compile 'com.github.ajithvgiri:Canvas-Library:v1.1.1'
26 | }
27 |
28 | ```
29 |
30 | ## 2. Add the Canvas View view to your Relative Layout xml file
31 |
32 | Make sure `layout_width` and `layout_height` are `match-parent`. and make sure the background of the layout must be white
33 |
34 | ``` xml
35 |
40 | ```
41 |
42 | ## 3. Add the canvas view to the layout
43 |
44 | ``` java
45 | RelativeLayout parentView = findViewById(R.id.parentView);
46 | CanvasView canvasView = new CanvasView(this);
47 | parentView.addView(canvasView);
48 | ```
49 |
50 | To clear the drawing
51 |
52 | ``` java
53 | canvasView.clearCanvas();
54 | ```
55 |
