ListView设置某一项item的文本居中

 1 this.adapter    = new ArrayAdapter<String>(this,android.R.layout.simple_list_item_1,data){
 2             @Override
 3             public boolean isEnabled(int position) {
 4                 return false; //设置item不能点击
 5             }
 6 
 7             @Override
 8             public View getView(int position, View convertView, ViewGroup parent) {
 9                 View view   =  super.getView(position, convertView, parent);
10                 TextView et     = (TextView)view;
11                 if(true==et.getText().toString().contains("天的天气")){
12                     et.setGravity(Gravity.CENTER);
13                 }else{
14                     et.setGravity(Gravity.LEFT); //这句是必须的-如果去掉来回滑动几次，会有错误的item居中
15                 }
16                 view        = (View)et;
17                 return view;
18             }
19         };
