ListView項文本重力

我使用Arrayadapter與android.R.layout.simple_list_item_1孩子這裏是getView功能ListView項文本重力

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

    if (convertView == null) 
     convertView = this.inflater.inflate(res, parent, false); 

    TextView textView = (TextView) convertView.findViewById(android.R.id.text1); 
    textView.setTextColor(ContextCompat.getColor(ctx, R.color.white_overlay)); 
    textView.setLayoutParams(new LinearLayout.LayoutParams(ViewGroup.LayoutParams.MATCH_PARENT, ViewGroup.LayoutParams.WRAP_CONTENT)); 
    //textView.setLayoutDirection(View.LAYOUT_DIRECTION_RTL); 

    textView.setText(filterData.get(position).getTitle()); 
    textView.setGravity(Gravity.CENTER_VERTICAL | Gravity.START); 

    return convertView; 

}

和IAM應用過濾器上這裏的列表數據的過濾器代碼私有類MyFilter擴大了濾波器{

@Override 
    protected FilterResults performFiltering(CharSequence charSequence) { 
     String filterStr = charSequence.toString().toLowerCase(); 
     FilterResults results = new FilterResults(); 

     int count = data.size(); 
     List<Extras.Area> tempRes = new ArrayList<>(count); 

     for (Extras.Area area : data) { 
      if (area.getArTitle().toLowerCase().contains(filterStr) 
        || area.getEnTitle().toLowerCase().contains(filterStr)) 
       tempRes.add(area); 
     } 

     results.values = tempRes; 
     results.count = tempRes.size(); 

     return results; 
    } 

    @SuppressWarnings("unchecked") 
    @Override 
    protected void publishResults(CharSequence charSequence, FilterResults filterResults) { 
     filterData = (List<Extras.Area>) filterResults.values; 
     notifyDataSetChanged(); 

    } 
}

我的問題是根據每個項目的文本重心始終即使在局部方向是RTL 離開這裏是一個例子
