我套路的自定义View 手势篇（二）

@Override
    public boolean onTouchEvent(MotionEvent event) {
         return super.onTouchEvent(event);
    }

public class MyView extends View{
    private String TAG = "MyView";
    private Paint paint;
    float x, y;

    public MyView(Context context) {
        super(context);
        initView();
    }

    public MyView(Context context, AttributeSet attrs) {
        super(context, attrs);
        initView();
    }

    public MyView(Context context, AttributeSet attrs, int defStyleAttr) {
        super(context, attrs, defStyleAttr);
        initView();
    }

    public void initView(){
        Log.d(TAG, "onCreat");
        paint = new Paint();
        paint.setColor(Color.RED);
    }


    @Override
    protected void onSizeChanged(int w, int h, int oldw, int oldh) {
        Log.d(TAG, "onSizeChanged");
        super.onSizeChanged(w, h, oldw, oldh);
    }

    @Override
    protected void onDraw(Canvas canvas) {
        Log.d(TAG, "onDraw");
        super.onDraw(canvas);
        canvas.drawCircle(x, y, 10, paint);
    }

    @Override
    public boolean onTouchEvent(MotionEvent event) {
        x = event.getX();
        y = event.getY();
        postInvalidate();
        return true;
    }
}
