实现流程：

1.初始化：对画笔进行设置

mPaintIn = new Paint(); mPaintIn.setAntiAlias(true); mPaintIn.setDither(true); mPaintIn.setStyle(Paint.Style.FILL); mPaintIn.setColor(getResources().getColor(R.color.colorPrimary)); mPaintOut = new Paint(); mPaintOut.setAntiAlias(true); mPaintOut.setDither(true); mPaintOut.setStyle(Paint.Style.FILL); mPaintOut.setColor(getResources().getColor(R.color.colorAccent));

2.绘制外框，内框，文字

获取组件宽高

int width = getMeasureWidth(); int height = getMeasureHeight();

绘制

@Override protected void onDraw(Canvas canvas) { //绘制背景,在绘制文字之前绘制 canvas.drawRect(new Rect(0, 0, getMeasuredWidth(), getMeasuredHeight()), mPaintIn); canvas.drawRect(new Rect(10, 10, getMeasuredWidth()-10, getMeasuredHeight()-10), mPaintOut); super.onDraw(canvas); }
