ListView點擊或選中item改變背景

點擊或選中ListView中的一項後，使item背景改變，失去焦點同樣顯示選中的背景，重新選中另外一項才刷新；

在Adapter中配置：

public class MyAdapter extends BaseAdapter{

 int mSelect = 0;   //選中項

     ......

 public void changeSelected(int positon){ //刷新方法
     if(positon != mSelect){
      mSelect = positon;
     notifyDataSetChanged();
     }
    }



public View getView(int position, View convertView, ViewGroup parent) {
//     if(convertView==null){
        LayoutInflater factory = LayoutInflater.from(context);
        View v = (View) factory.inflate(R.layout.list_item, null);
        TextView tv = (TextView) v.findViewById(R.id.Item_tv);
        tv.setText("test");
//     }
        if(mSelect==position){    
         v.setBackgroundResource(R.drawable.fc_bg);  //選中項背景
        }else{
         v.setBackgroundResource(R.drawable.bg);  //其他項背景
        }

        return v;
    }

}

配置好了之後，下面就是應用：

...........

mAdapter = new MyAdapter(...);

myList.setAdapter(mAdapter);

//////////點擊監聽

myList.setOnItemClickListener(new OnItemClickListener() {

  @Override
  public void onItemClick(AdapterView<?> parent, View view, int position, long id) {
          mAdapter.changeSelected(position);//刷新

  }......}

////////////////選中監聽

myList.setOnItemSelectedListener(new OnItemSelectedListener() {

  @Override
  public void onItemSelected(AdapterView<?> parent, View view, int position, long id) {
            mAdapter.changeSelected(position);//刷新

  }......}
