특정 상대 레이아웃에서만 edittext 또는 imageview를 이동하는 방법은 무엇입니까?

Question

public class MyActivity extends Activity implements View.OnTouchListener { 

    TextView _view; 
    ViewGroup _root; 
    private int _xDelta; 
    private int _yDelta; 

    @Override 
    public void onCreate(Bundle savedInstanceState) { 
     super.onCreate(savedInstanceState); 
     setContentView(R.layout.main); 

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

     _view = new TextView(this); 
     _view.setText("TextView!!!!!!!!"); 

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

     _view.setOnTouchListener(this); 
     _root.addView(_view); 
    } 

    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: 
       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; 
    }} 

edittext와 imageview.It을 움직이는 데이 코드를 사용하고 있습니다. 잘 움직이고 있지만 상대 레이아웃 외에도 이동합니다. 레이아웃을 이동하는 데 제약이 따릅니다. 아무에게도 제안이 있습니까? 내가 구현하는 아래
