Android 4.2.2上的黑色背景

Question

我有一個令人難以置信的問題TextView在ListView。 TextView第一排ListView在Android 4.2.2上有黑色。 （Nexus 4）在Android 4.2.1以上，它沒有顏色。在我的HTC One上一切正常，直到我收到更新到4.2.2。現在TextView s的前兩行有黑色背景。來自Nexus的第一行黑色的screenshot表示更多。適配器的

代碼如下：

public class NotificationsAdapter extends ArrayAdapter<Object> { 

private ArrayList<Object> items; 
Context context;  
private LayoutInflater mInflater; 
Typeface rb; 
Typeface bn; 
Typeface rr; 
Typeface rbc; 

public NotificationsAdapter(Context context, int textViewResourceId, ArrayList<Object> items) { 
     super(context, textViewResourceId, items);  
     this.context = context;    
     this.items = items; 
     mInflater = (LayoutInflater)getContext().getSystemService(Context.LAYOUT_INFLATER_SERVICE); 
     rb = Typeface.createFromAsset(getContext().getAssets(), "Roboto-Bold.ttf"); 
     bn = Typeface.createFromAsset(getContext().getAssets(), "BebasNeue.otf"); 
     rr = Typeface.createFromAsset(getContext().getAssets(), "Roboto-Regular.ttf"); 
     rbc = Typeface.createFromAsset(getContext().getAssets(), "Roboto-BoldCondensed.ttf"); 
} 

@Override 
public View getView(int position, View convertView, ViewGroup parent) {  

     int type; 
     if(items.get(position).getClass().equals(String.class)) 
      type = 0; 
     else 
      type = 1;   

     if(type == 0){ 
      String m = (String)items.get(position); 
      if (m != null) {     
       convertView = mInflater.inflate(R.layout.notification_month_row, null); 
       TextView month_date = (TextView)convertView.findViewById(R.id.tw_notification_month); 
       month_date.setTypeface(rb); 
       month_date.setText(m);      
      } 
     } 
     else{       
      Notifications o = (Notifications)items.get(position); 
      if (o != null) { 
       convertView = mInflater.inflate(R.layout.notification_row, null); 
       TextView month_date = (TextView)convertView.findViewById(R.id.tw_notification_date); 
       TextView title = (TextView)convertView.findViewById(R.id.tw_notification_title); 
       TextView note = (TextView)convertView.findViewById(R.id.tw_notification_description); 
       ImageView mark = (ImageView)convertView.findViewById(R.id.iv_notification_marker); 
       title.setTypeface(bn); 
       title.setText(o.getTitle());      
       note.setTypeface(rr); 
       note.setText(o.getDescription());      
       month_date.setTypeface(rbc); 
       month_date.setText(o.getDate());       
       if(o.getConfirmed().equals("1")){ 
        mark.setVisibility(4); 
       }else{ 
        mark.setVisibility(0); 
       }          
      } 
     } 

     return convertView; 
    } 

有誰有它爲什麼發生任何想法？

XML這裏：

Answer 1

不知道這是否會幫助，但你不正確使用LayoutInflater：

convertView = mInflater.inflate(R.layout.notification_month_row, null); 

它應該是：

convertView = mInflater.inflate(R.layout.notification_month_row, parent, false); 

使用fo rmer有時會給我奇怪的渲染問題。
