Android onTouch 监听器事件

Question

我正在使用 ontouch 事件，但我遇到的问题是它调用了 down 事件，但它没有调用 move 事件或 UP 事件检查以下代码

public class DragNewActivity extends Activity implements OnTouchListener  {

    private float X;
    private float Y;
    private int width;
    private int height;
    private CharSequence s;

    /** Called when the activity is first created. */
    @Override
    public void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.main);

        Log.d("D","D");

        TextView tv1 = (TextView)findViewById(R.id.tv1);
        TextView tv2 = (TextView)findViewById(R.id.tv2);
        tv1.setOnTouchListener(this);
        //tv2.setOnTouchListener(this);
        }

    @Override
    public boolean onTouch(View v, MotionEvent event) {

        //int action = event.getAction();
        switch (event.getAction()){
        case MotionEvent.ACTION_DOWN:
            Log.d("DOWN","DOWN");
        break;

        case MotionEvent.ACTION_MOVE:
            Log.d("MOVE","MOVE");
        break;

        case MotionEvent.ACTION_UP:
            Log.d("UP","UP");
            X = event.getRawX();
            Y = event.getRawY();

            Display display = getWindowManager().getDefaultDisplay(); 
            width=display.getWidth()/2;
            height=display.getHeight()/2;
            Log.e("X", X+"");
            Log.e("Y", Y+"");
            Log.e("ScX", width+"");
            Log.e("ScY", height+"");
            if(X>width && Y>height){
                Log.e("SUFI", "Event ho gyuaaaaaaa");
            }

        break;
        }
        return false;
    }
}

不要从ontouch 返回false 返回true 以便它会监听下一个 Action 事件
