不用Drawable来实现Imageview的点击效果

public class ClickImageView extends AppCompatImageView {

public ClickImageView(Context context, AttributeSet attrs, int defStyleAttr) {
super(context, attrs, defStyleAttr);
init();
}

public ClickImageView(Context context, AttributeSet attrs) {
super(context, attrs);
init();
}

public ClickImageView(Context context) {
super(context);
init();
}

private void init() {
setOnTouchListener(onTouchListener);
}

private OnTouchListener onTouchListener = new OnTouchListener() {
@Override
public boolean onTouch(View v, MotionEvent event) {
switch (event.getAction()) {
case MotionEvent.ACTION_UP:
setColorFilter(null);
break;
case MotionEvent.ACTION_DOWN:
changeLight();
break;
case MotionEvent.ACTION_MOVE:
break;
case MotionEvent.ACTION_CANCEL:
setColorFilter(null);
break;
default:
break;
}
return false;
}
};

private void changeLight() {
int brightness = -80;
ColorMatrix matrix = new ColorMatrix();
matrix.set(new float[]{1, 0, 0, 0, brightness, 0, 1, 0, 0,
brightness, 0, 0, 1, 0, brightness, 0, 0, 0, 1, 0});
setColorFilter(new ColorMatrixColorFilter(matrix));
}
}
