Add things in ListView head and tail

Directly on the code

 2 import android.os.Bundle;
 3 import android.view.LayoutInflater;
 4 import android.view.View;
 5 import android.widget.ArrayAdapter;
 6 import android.widget.Button;
 7 import android.widget.ListView;

10 import java.util.List;

12 public class MainActivity extends AppCompatActivity {
13     private ListView lv;
14     private List<String>list;
15     private ArrayAdapter<String>adapter;
16     @Override
17     protected void onCreate(Bundle savedInstanceState) {
18         super.onCreate(savedInstanceState);
19         setContentView(R.layout.activity_main);
20         //初始化控件
21         lv=(ListView)findViewById(R.id.lv);
22         //初始化数据
23         list=new ArrayList<String>();
24         for (int0 = I; I <20 is; I ++ ) {
 25              List.add ( "display content" + I);
 26 is          }
 27          // initialize adapter 
28          Adapter = new new the ArrayAdapter <String> ( the this , android.R.layout.simple_expandable_list_item_1 , List);
 29          // the xml file into View objects 
30          View image LayoutInflater.from = ( the this ) .inflate (R.layout.image_item, null );
 31 is          // put into ListView picture header 
32          lv.addHeaderView (Image);
 33 is          the Button BTN = new new the Button ( the this );
 34 is         btn.setText ( "Load more" );
 35          // put the buttons ListView tail 
36          lv.addFooterView (BTN);
 37 [          // set the adapter 
38 is          lv.setAdapter (Adapter);
 39      }
 40 }

Newly learned is to use two methods is addHeaderView addFooterView

There are two xml files
