的ListView CAB經過項目着色

我在一個損失，因爲我覺得自己像機器人應該採取的這種默認選擇行爲護理...的ListView CAB經過項目着色

我使用actionbarsherlock與ListView和有上下文操作欄出現項目長按後。我希望這些項目在長按之後突出顯示，但他們只是做初始閃爍的藍色變暗，然後恢復爲默認顏色。我錯過了什麼嗎？

mHabitListView.setAdapter(mAdapter); 
    mHabitListView.setChoiceMode(ListView.CHOICE_MODE_MULTIPLE); 
    mHabitListView.setOnItemLongClickListener(new OnItemLongClickListener() { 

     @Override 
     public boolean onItemLongClick(AdapterView<?> parent, View view, 
       int position, long id) { 

       if (mHabitListView.isItemChecked(position)){ 
        mHabitListView.setItemChecked(position, false); 


       } else { 
        mHabitListView.setItemChecked(position, true); 

       } 

       if (mHabitListView.getCheckedItemCount() > 0) { 

        if (mMode == null) { 
         mMode = startActionMode(new ModeCallback()); 
        } else { 
         mMode.setTitle(mHabitListView.getCheckedItemCount() + " " + getString(R.string.cab_selected_count)); 

        } 
       } else { 
        if (mMode != null) { 
         mMode.finish(); 

        } 
       } 
       return true; 
      } 

    }); 






} 

@Override 
public boolean onCreateOptionsMenu(Menu menu) { 
    // Inflate the menu; this adds items to the action bar if it is present. 
    getSupportMenuInflater().inflate(R.menu.activity_main, menu); 
    return true; 
} 

@Override 
public boolean onOptionsItemSelected(MenuItem item) { 
    // Handle item selection 
    switch (item.getItemId()) { 
     case R.id.menu_add_new_habit: 
      Habit h = new Habit("Floss", "GOOD", "", ""); 

      mDbHelper.createHabitEntry(h); 
      mDbHelper.close(); 

      Cursor cursor = mDbHelper.getAllEntries(); 
      mAdapter.changeCursor(cursor); 

      break; 
    } 
    return true; 
} 



private final class ModeCallback implements ActionMode.Callback { 

     @Override 
     public boolean onCreateActionMode(ActionMode mode, Menu menu) { 
      // Create the menu from the xml file 
      MenuInflater inflater = getSupportMenuInflater(); 
      mode.setTitle(mHabitListView.getCheckedItemCount() + " " + getString(R.string.cab_selected_count)); 
      inflater.inflate(R.menu.list_contextual_menu, menu); 
      return true; 
     } 

     @Override 
     public boolean onPrepareActionMode(ActionMode mode, Menu menu) { 
      // Here, you can checked selected items to adapt available actions 
      return false; 
     } 

     @Override 
     public void onDestroyActionMode(ActionMode mode) { 
      // Destroying action mode, let's unselect all items 
      for (int i = 0; i < mHabitListView.getAdapter().getCount(); i++) 
       mHabitListView.setItemChecked(i, false); 

      if (mode == mMode) { 
       mMode = null; 
      } 
     } 

     @Override 
     public boolean onActionItemClicked(ActionMode mode, MenuItem item) { 
      long[] selected = mHabitListView.getCheckedItemIds(); 
      if (selected.length > 0) { 
       for (long id: selected) { 
        // Do something with the selected item 
       } 
      } 
      mode.finish(); 
      return true; 


     } 


    }

您可以使用您列表項的 android.R.layout.simple_list_item_activated_2

mAdapter = new SimpleCursorAdapter(this, android.R.layout.simple_list_item_activated_2, 
    null, 
    new String[] { Favorite.BUS_NAME, Favorite.STATION_NAME }, 
    new int[] { android.R.id.text1, android.R.id.text2, }, 0); 
setListAdapter(mAdapter);

我不會限制自己的佈局，我有我使用的自定義列表視圖行佈局 – joepetrakovich

設置背景爲android:background="?android:attr/activatedBackgroundIndicator"

，如果你仍然面臨的任何問題然後嘗試刪除listSelector屬性從你的ListView xml
