ListView

界面的创建一：

<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
    xmlns:tools="http://schemas.android.com/tools"
    android:id="@+id/activity_main"
    android:layout_width="match_parent"
    android:layout_height="match_parent"
    android:paddingBottom="@dimen/activity_vertical_margin"
    android:paddingLeft="@dimen/activity_horizontal_margin"
    android:paddingRight="@dimen/activity_horizontal_margin"
    android:paddingTop="@dimen/activity_vertical_margin"
    tools:context="lenovo_com.listview.MainActivity">

    <ListView
        android:id="@+id/list_item"
        android:layout_width="match_parent"
        android:layout_height="match_parent"
        android:scrollbars="vertical"/>
二：

<LinearLayout
    xmlns:android="http://schemas.android.com/apk/res/android"
    android:orientation="vertical"
    android:layout_width="match_parent"
    android:layout_height="match_parent">
    <LinearLayout
        android:layout_width="match_parent"
        android:layout_height="match_parent"
        android:orientation="vertical">
        <TextView
            android:id="@+id/name"
            android:layout_width="wrap_content"
            android:layout_height="wrap_content"
             />
        <TextView
            android:id="@+id/age"
            android:layout_width="wrap_content"
            android:layout_height="wrap_content"
            />
        <TextView
            android:id="@+id/address"
            android:layout_width="wrap_content"
            android:layout_height="wrap_content"
             />
实现listview的功能：
首先定义

public class MainActivity extends AppCompatActivity {
    private String[] name={"李美丽","杨漂亮","周淑女","李英俊","邓言狗"};
    private int [] age={19,20,21,22,23};
    private String[] adress={"永川区","合川区","沙坪坝","北碚","渝北区"};
    private ListView listView;


    @Override
    protected void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.activity_main);
导入：

        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);
        }
运用for循环进行挨个装入 然后再用适配器进行映射
        SimpleAdapter simplead = new SimpleAdapter(this, listems,R.layout.activity2, new String[] { "name", "age", "adress" },
                new int[] {R.id.name,R.id.age,R.id.address});
        listView=(ListView)findViewById(R.id.list_item);
        listView.setAdapter(simplead);

    }

}
