и когда я нажимаю Я использую этот код:

.... 
    DataContainer = (LinearLayout) rootView.findViewById(R.id.datacontainer); 
     IngContainer = (LinearLayout) rootView.findViewById(R.id.ingcontainer); 
.... 

    ArrowExpand.setOnClickListener(new View.OnClickListener() { 

      @Override 
      public void onClick(View arg0) { 

       if (DataContainer.getVisibility() == View.VISIBLE) { 
        // Its visible 
        DataContainer.setVisibility(View.GONE); 
        ObjectAnimator flip = ObjectAnimator.ofFloat(ArrowExpand, "rotationX", 180f, 0f); 
        flip.setDuration(500); 
        flip.start(); 
       } else { 
        // Either gone or invisible 
        DataContainer.setVisibility(View.VISIBLE); 
        ObjectAnimator flip = ObjectAnimator.ofFloat(ArrowExpand, "rotationX", 0f, 180f); 
        flip.setDuration(500); 
        flip.start(); 
       } 
      } 
     }); 

Как удалить разрыв? Мне хотелось бы, чтобы у второго LinearLayout появился первый LinearLayout, и только когда я нажимаю на стрелку, у меня есть разложение. Можно ли удалить и название сверху (MyViewRecip ...)?

THX.

Answer 1

вы можете сохранить свой вид первый, который вы хотите удалить, а затем удалить этот ребенок

Answer 2

Просто попробуйте изменить вес макета programmily

 LinearLayout.LayoutParams lp = new LinearLayout.LayoutParams(0, 100); 
    lp.weight = 1; 

     if (DataContainer.getVisibility() == View.VISIBLE) { 
         // Its visible 
         DataContainer.setVisibility(View.GONE); 
    DataContainer.setLayoutParams(lp); 
         ObjectAnimator flip = ObjectAnimator.ofFloat(ArrowExpand, "rotationX", 180f, 0f); 
         flip.setDuration(500); 
         flip.start(); 
        } else { 
         // Either gone or invisible 
lp.weight = 70; 
         DataContainer.setVisibility(View.VISIBLE); 
    DataContainer.setLayoutParams(lp); 
         ObjectAnimator flip = ObjectAnimator.ofFloat(ArrowExpand, "rotationX", 0f, 180f); 
         flip.setDuration(500); 
         flip.start(); 
        } 

Я думаю, что это может решить вашу проблему ..
