如何建立保證金運動圖像視圖的Android

Question

請給我品嚐移動圖像到我的保證金目的地

ilustration

image  x (margin move image) 

如果圖像與拖動圖像移動罷移動到我的保證金

imageView.setOnTouchListener(new OnTouchListener() { 

      public boolean onTouch(View v, MotionEvent event) { 
       // TODO Auto-generated method stub 
       int eid = event.getAction(); 
       switch (eid) { 
       case MotionEvent.ACTION_MOVE: 
        RelativeLayout.LayoutParams mParams = (RelativeLayout.LayoutParams) imageView.getLayoutParams(); 
        int x = (int) event.getRawX(); 
        //int y = (int) event.getRawY(); 
        TextView text = (TextView) findViewById(R.id.editText1); 
        text.setText("1"); 
        mParams.setMargins(0, 0, 70, 0); 
        mParams.leftMargin = x+0; 
        //mParams. 

        imageView.setLayoutParams(mParams); 

        break; 
       default: 
        break; 
       } 
       return true; 
      } 
     } 

Answer 1

FrameLayout.LayoutParams params = new FrameLayout.LayoutParams(
     LayoutParams.WRAP_CONTENT, LayoutParams.WRAP_CONTENT, 
     Gravity.NO_GRAVITY); 

我錯過了第三個參數（Gravity.NO_GRAVITY）。使用它你可以在任何設置寬度/高度的位置放置視圖。
