Listview and Adapte

一、XML代码

1、<ListView
           android:layout_width="match_parent"
           android:layout_height="match_parent"
           android:id="@+id/listitem">
    
       </ListView>
       

2、<LinearLayout
        android:layout_width="match_parent"
        android:layout_height="match_parent"
        android:orientation="vertical">
    <TextView
        android:layout_width="wrap_content"
        android:layout_height="wrap_content"
        android:id="@+id/name" />
    <TextView
        android:layout_width="wrap_content"
        android:layout_height="wrap_content"
        android:id="@+id/age" />
        <TextView
            android:layout_width="wrap_content"
            android:layout_height="wrap_content"
            android:id="@+id/address" />
</LinearLayout>


二、JAVA代码及功能实现
   
   public class MainActivity extends AppCompatActivity {
    private String[] name={"科比","詹姆斯","库里","张伯伦","乔丹"};
    private int [] age={38,33,29,63,54};
    private String[] adress={"美国","美国","美国","美国","美国"};
    private ListView lv;
    @Override
    protected void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.activity_main);
        List<Map<String, Object>> listems = new ArrayList<>();
        for (int i = 0; i < name.length; i++) {
            Map<String, Object> listem = new HashMap<>();
            listem.put("name", "姓名："+name[i]);
            listem.put("age", "年龄："+age[i]);
            listem.put("adress", "地址："+adress[i]);
            listems.add(listem);
        }
        SimpleAdapter simplead = new SimpleAdapter(this, listems,R.layout.activity_lists2, new String[] { "name", "age", "adress" },
                new int[] {R.id.name,R.id.age,R.id.address});
        lv=(ListView)findViewById(R.id.listitem);
        lv.setAdapter(simplead);
    }
}
