android - 如何获取 android Activity 或控制触摸计数？

Question

我想获取 Activity 或任何控制元素的触摸计数。像 Android 4.2 on nexus Developer options Enable while touch 7 times.

处理它的合适事件是什么？

Answer 1

你得到 2 个计数，因为每次触摸事件被调用时都会调用触摸事件，比如向下和向上(例如)

    @Override
public boolean onTouchEvent(MotionEvent event) {
    int action = MotionEventCompat.getActionMasked(event);
    switch (action) {
    case MotionEvent.ACTION_DOWN:
        //add here the counter if you want when screen pressed
                    break;
    case MotionEvent.ACTION_UP:
        //add here the counter if you want when touch released
                    break;
    default:
        return super.onTouchEvent(event);
    }
}
