拖動時將數據附加到不同視圖

Question

我有多個視圖被拖動，每個視圖都表示一種情感。這個想法是讓每個視圖向一個數據庫發送一個條目，該條目根據拖動的視圖而變化。

的意見在這裏創造：

_root = (ViewGroup)findViewById(R.id.root); 

_view = new ImageView(this); 
_view.setImageResource(R.drawable.smile); 
_view2 = new ImageView(this); 
_view2.setImageResource(R.drawable.frown); 



RelativeLayout.LayoutParams layoutParams = new RelativeLayout.LayoutParams(150, 50); 
layoutParams.leftMargin = 250; 
layoutParams.topMargin = 250; 
layoutParams.bottomMargin = -250; 
layoutParams.rightMargin = -250; 
_view.setLayoutParams(layoutParams); 
_view.setOnTouchListener(this); 

RelativeLayout.LayoutParams layoutParams2 = new RelativeLayout.LayoutParams(150, 50); 
layoutParams2.leftMargin = 250; 
layoutParams2.topMargin = 500; 
layoutParams2.bottomMargin = -250; 
layoutParams2.rightMargin = -250; 
_view2.setLayoutParams(layoutParams2); 
_view2.setOnTouchListener(this); 
_root.addView(_view); 
_root.addView(_view2); 

} 

而且運動和阻力在這裏定義：

public boolean onTouch(View view, MotionEvent event) { 
    final int X = (int) event.getRawX(); 
    final int Y = (int) event.getRawY(); 
    switch (event.getAction() & MotionEvent.ACTION_MASK) { 
     case MotionEvent.ACTION_DOWN: 
      RelativeLayout.LayoutParams lParams = (RelativeLayout.LayoutParams) view.getLayoutParams(); 
      _xDelta = X - lParams.leftMargin; 
      _yDelta = Y - lParams.topMargin; 
      break; 
     case MotionEvent.ACTION_UP: 
      Intent intent = new Intent(this, Exit_Activity.class); 
     startActivity(intent); 
      break; 
     case MotionEvent.ACTION_POINTER_DOWN: 
      break; 
     case MotionEvent.ACTION_POINTER_UP: 
      break; 
     case MotionEvent.ACTION_MOVE: 
      RelativeLayout.LayoutParams layoutParams = (RelativeLayout.LayoutParams) view.getLayoutParams(); 
      layoutParams.leftMargin = X - _xDelta; 
      layoutParams.topMargin = Y - _yDelta; 
      layoutParams.rightMargin = -250; 
      layoutParams.bottomMargin = -250; 
      view.setLayoutParams(layoutParams); 
      break; 
    } 
    _root.invalidate(); 
    return true; 
} 

} 

正如你所看到的，ACTION_UP目前向用戶發送到下一個活動，不管哪個視圖被拖動。讓應用程序區分視圖的最佳方式是什麼？

Answer 1

爲各個視圖設置ID。當點擊視圖時檢索ID。 ID是每個視圖的唯一標識。要設置ID：

view.setId(x); 

單擊時，檢索ID：

id = view.getId();
