是否可以在同一Textview上使用拖动事件和单击事件？

Question

在我的应用程序中,我要求在同一textView上使用单击和拖动事件.

我写了以下代码:

    switch(event.getAction())
        {
        case MotionEvent.ACTION_UP:
//          TextDialog.setVisibility(View.VISIBLE);
            break;
        case MotionEvent.ACTION_DOWN: {
            disallowTouch(parent, true);
           int downX = (int)event.getX();
           int downY = (int)event.getY();
            return false; // allow other events like Click to be processed
        }


        case MotionEvent.ACTION_MOVE:
                                        int x = (int)event.getRawX();
                                        int y= (int)event.getRawY();



                                        layoutParams.leftMargin = x - 50;
                                        layoutParams.topMargin = y - 70;


                                        tvText.setLayoutParams(layoutParams);
                                        break;


              default:
                                        break;
        }


        }
         return true;
    }

@Override
public void onClick(View v) {
    // TODO Auto-generated method stub
    TextDialog.setVisibility(View.VISIBLE);
}

但只有Action_Move正在运行,onClick事件不会被触发.

我只想在单击TextView时显示一个对话框.

我怎样才能做到这一点？

同时使用 setOnTouchListener 和 setOnClickListener

在 onTouch 中：

public boolean onTouch(View v, MotionEvent event) {
    ViewParent parent = v.getParent();
    switch (event.getAction()) {
    case MotionEvent.ACTION_DOWN: {
        disallowTouch(parent, true);
        downX = event.getX();
        downY = event.getY();
        return false; // allow other events like Click to be processed
    }
}

private void disallowTouch(ViewParent parent, boolean isDisallow) {
    if (parent != null) {
        parent.requestDisallowInterceptTouchEvent(isDisallow);
    }
}
