Android develops a method to realize rounded rectangle based on drawable

This paper describes the method of developing rounded rectangle based on drawable for Android. Share with you for your reference, as follows:

Step 1: write a class to inherit drawable, rewrite the methods inside, and the core code of the implementation is in draw

Key technology: bitmapshader

public BitmapShader(Bitmap bitmap,Shader.TileMode tileX,Shader.TileMode tileY)

Call this method to generate a shader with a bitmap drawn.

Bitmap tile the tiling mode for X to draw the bitmap in. Tile the tiling mode for y to draw the bitmap in. Tile the tiling mode for y to draw the bitmap in

Tilemode: clamp: if the renderer is outside the original boundary, the edge coloring in the range is copied. Repeat: repeat renderer images horizontally and vertically, tiled. Mirror: horizontal and vertical repeat renderer images. This is different from repeat repeat. It is tiled in a mirror way.

Step 2: implementation class

activity_ round_ drawable.xml

Draw a circular picture
