GestureDetector手势相关

使用GestureDetector或者onTouchEvent建议:

判断滑动的时候使用onTouchEvent  判断双击的情况下使用GestureDetector

public class ViewBaseKnowledge extends AppCompatActivity implements GestureDetector.OnGestureListener,GestureDetector.OnDoubleTapListener{
    
    GestureDetector gestureDetector;
    private static final String TAG = "ViewBaseKnowledge";
    @Override
    protected void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.activity_view_base_knowledge);
        gestureDetector=new GestureDetector(this);

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


        /*switch (event.getAction()){
            case MotionEvent.ACTION_DOWN:
                Log.e(TAG, "onTouchEvent: ACTION DOWN" );

                break;
            case MotionEvent.ACTION_MOVE:
                Log.e(TAG, "onTouchEvent: ACTION_MOVE" );
                break;
            case MotionEvent.ACTION_UP:
                Log.e(TAG, "onTouchEvent: ACTION_UP" );
                break;
        }*/
        return super.onTouchEvent(event);
    }

    @Override
    public boolean onDown(MotionEvent e) {
        Log.e(TAG, "手指轻触屏幕的瞬间" );
        return false;
    }

    @Override
    public void onShowPress(MotionEvent e) {
        Log.e(TAG, "轻触屏幕尚未松开或者是拖动" );
    }

    @Override
    public boolean onSingleTapUp(MotionEvent e) {
        Log.e(TAG, "单击行为" );
        return false;
    }

    @Override
    public boolean onScroll(MotionEvent e1, MotionEvent e2, float distanceX, float distanceY) {
        Log.e(TAG, "按下屏幕并且拖动" );
        return false;
    }

    @Override
    public void onLongPress(MotionEvent e) {
        Log.e(TAG, "长按屏幕" );
    }

    @Override
    public boolean onFling(MotionEvent e1, MotionEvent e2, float velocityX, float velocityY) {
        Log.e(TAG, "快速的滑动" );
        return false;
    }

    @Override
    public boolean onSingleTapConfirmed(MotionEvent e) {
        Log.e(TAG, "严格的单击行为" );
        return false;
    }

    @Override
    public boolean onDoubleTap(MotionEvent e) {
        Log.e(TAG, "双击 两次连续单击组成" );
        return false;
    }

    @Override
    public boolean onDoubleTapEvent(MotionEvent e) {
        Log.e(TAG, "发生了双击行为" );
        return false;
    }
}
