BottomSheetBehavior与GridView闪烁

Question

我试图在bottomSheetBehavior内使用gridView。
我得到我的数据异步，并且当用户点击我的按钮时我打电话给setAdapter。 问题是我看到数据闪烁。我能做些什么来杀死这个闪烁？

以我的onCreate：

final ViewGroup gridViewContainer = (ViewGroup) findViewById(R.id.bottomSheetContainer); 
    if (gridViewContainer != null) { 
    gridView = (GridView) gridViewContainer.findViewById(R.id.actionGridView); 
    bottomSheetBehavior = BottomSheetBehavior.from(gridViewContainer); 
    bottomSheetBehavior.setBottomSheetCallback(new BottomSheetBehavior.BottomSheetCallback() { 
     @Override 
     public void onStateChanged(@NonNull View bottomSheet, int newState) { 
      switch (newState) { 
       case BottomSheetBehavior.STATE_EXPANDED: 
        isBottomSheetQuickActionOpen = true; 
        gridViewContainer.requestLayout(); 
        break; 
       case BottomSheetBehavior.STATE_COLLAPSED: 
        isBottomSheetQuickActionOpen = false; 
        break; 
      } 
     } 

     @Override 
     public void onSlide(@NonNull View bottomSheet, float slideOffset) { 

     } 
    }); 

public void onBottomBarIconClicked(View v){ 
    switch(v.getId()){ 
     case R.id.right_bottom_action: 
      if (bottomSheetBehavior != null) { 
       if (!isBottomSheetQuickActionOpen) { 
        setActionsForQuickDialog(); 
        bottomSheetBehavior.setState(BottomSheetBehavior.STATE_EXPANDED); 
       } else { 
        bottomSheetBehavior.setState(BottomSheetBehavior.STATE_COLLAPSED); 
       } 
      } 
      break; 
    } 
} 

private void setupQuickActionDialog() { 
    ActionsManager actionManager = ActionsManager.get(); 
    List<WidgetMetaData> list = getMyList(); 
    if (CollectionUtils.isNotEmpty(list)) { 
     if (gridView != null) { 
      adapterGridView = new AdapterGridView(ContactDetailsActivity.this, list, contact); 
      gridView.setAdapter(adapterGridView); 
     } 
    } 
}

我发现一种解决方案，方式：
1.可运行

private final Runnable runnable = new Runnable() { 
     @Override 
     public void run() { 
       if (!isBottomSheetQuickActionOpen) { 
        bottomSheetBehavior.setState(BottomSheetBehavior.STATE_EXPANDED); 
       } else { 
        bottomSheetBehavior.setState(BottomSheetBehavior.STATE_COLLAPSED); 
       } 
     } 
    }; 

保存主的保存部件线程：

Handler mainHandler = new Handler（context.getMainLooper（））;

单击按钮时，首先创建gridview图标，然后使用mainthread来发布可运行。如果我们想要折叠bottomsheetbehaviour，我们应该从队列中删除可运行内容，然后通过崩溃

setBottomSheetState（BottomSheetBehavior.STATE_COLLAPSED）;

更改过的功能：

public void onBottomBarIconClicked(View v) { 
    switch (v.getId()) { 
     case R.id.open_menu_btn: 
      if (bottomSheetBehavior != null) { 
       if (!isBottomSheetQuickActionOpen) { 
        setActionsForQuickDialog(); 
        mainHandler.post(runnable); 
       } else { 
        handler.removeCallbacks(runnable); 
        collapseBottomSheet(); 
       } 
      } 
      break; 
    } 
}
