拖放文本视图 [英] drag and drop textview

问题描述

我必须拖动，但无法完美拖动:问题是:1)我必须拖动两到三次才能将其带到所需的位置.因此 textview 不能顺利地跟随手指移动.2)如果我向上移动 textview 它只会向下移动.

I have to drag and i am not able to drag it perfectly: The issues are: 1) I have to drag two to three times to bring that to desired position.Hence textview is not following the finger movement smoothly. 2)If i move textview in upward direction its only going downwards.

我正在提供有关触摸事件的 textview 代码.请帮助.提前致谢.

I am providing the code of textview on touch event.Please help.Thanks in advance.

 final TextView t=(TextView)findViewById(R.id.textView4);
           t.setOnTouchListener(new OnTouchListener(){

            public boolean onTouch(View v, MotionEvent me) {
                    // TODO Auto-generated method stub
                float x = me.getX();
                float y = me.getY();

                if (me.getAction() == MotionEvent.ACTION_DOWN) {
                    status = START_DRAGGING;
                }
                if (me.getAction() == MotionEvent.ACTION_UP) {
                    status = STOP_DRAGGING;
                    t.setPadding((int) me.getX(), (int) me.getY(), 10, 10);

                    Log.i("Drag", "Stopped Dragging");
                }  if (me.getAction() == MotionEvent.ACTION_MOVE) {
                    if (status == START_DRAGGING) {
                        System.out.println("Dragging");

                        t.setPadding((int) me.getX(), (int) me.getY(), 10, 10);

                        t.invalidate();
                    }
                }return true;
            }}); 

推荐答案

也许你是 在 Android 中没有按照应有的方式移动 View?

setPadding() 不是最好的方法.

这里 是拖放的另一种方式 for 查看s
