我正在嘗試使列表視圖行爲空,如果它沒有文本。我之前已經實現了這一點,但我不確定我是如何做到的。目前,當文本沒有任何內容時,我設法讓它不顯示任何內容,但它仍然顯示行邊界。Android - 使列表視圖行不可見

ArrayAdapter<String> adapter = new ArrayAdapter<String>(this, android.R.layout.simple_list_item_2, android.R.id.text1, MainActivity.values) { 
       @Override 
       public View getView(int position, View convertView, ViewGroup parent) { 
       View view = super.getView(position, convertView, parent); 
       TextView text1 = (TextView) view.findViewById(android.R.id.text1); 
       TextView text2 = (TextView) view.findViewById(android.R.id.text2); 


       text1.setText(MainActivity.values[position]); 
       text2.setText(MainActivity.numvalues[position]); 

        if (MainActivity.values[position].equals("")) { 
         text1.setVisibility(View.INVISIBLE); 
         text1.setVisibility(View.GONE); 
         text2.setVisibility(View.INVISIBLE); 
         text2.setVisibility(View.GONE); 
         //convertView.setVisibility(View.INVISIBLE); 
         //convertView.setVisibility(View.GONE); 
         view.setVisibility(View.INVISIBLE); 
         view.setVisibility(View.GONE); 
        } 
        else { 
         text1.setVisibility(View.VISIBLE); 
         text2.setVisibility(View.VISIBLE); 
         //convertView.setVisibility(View.INVISIBLE); 
         //convertView.setVisibility(View.GONE); 
         view.setVisibility(View.VISIBLE); 
        } 

       return view; 
       } 
      };

爲什麼你設置可見性**兩次**? 'GONE'就夠了。節省CPU週期! –

在init ArrayAdapter從MainActivity.values和MainActivity.numvalues項中移除之前,不需要顯示。

VIEW.GONE將無法​​正常工作,我試過了,但有一件事你可以做,以避免這個問題,也許你應該刪除你所有的空行,適配器?
