要想实现输出内容的显示,就得给它们一个输出空间
首先是xml的布局
<?xml version="1.0" encoding="utf-8"?> <LinearLayout xmlns:android="http://schemas.android.com/apk/res/android" xmlns:app="http://schemas.android.com/apk/res-auto" xmlns:tools="http://schemas.android.com/tools" android:layout_width="match_parent" android:layout_height="match_parent" tools:context="com.example.list.listshow"> <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/age" /> <TextView android:layout_width="wrap_content" android:layout_height="wrap_content" android:id="@+id/address" /> <TextView android:layout_width="wrap_content" android:layout_height="wrap_content" android:id="@+id/name" /> </LinearLayout> </LinearLayout>
然后是MainActivity
public class MainActivity extends AppCompatActivity { //先声明我要里面添加的信息和对ListView进行初始化 private String[] name={"王","千","大","哥"}; private int [] age={25,30,15,19,25}; private String[] adress={"江宁区","栖霞区","鼓楼区","江北区"}; private ListView lv; @Override protected void onCreate(Bundle savedInstanceState) { super.onCreate(savedInstanceState); setContentView(R.layout.activity_main); //以下创建集合将内容装入 List<Map<String, Object>> listems = new ArrayList<>(); for (int i = 0; i < name.length; i++) { Map<String, Object> listem = new HashMap<>(); listem.put("name", "年龄:"+age[i]); listem.put("age", "地址:"+adress[i]); listem.put("adress", "姓名:"+name[i]); listems.add(listem); }//运用for循环进行挨个装入 SimpleAdapter simplead = new SimpleAdapter(this, listems,R.layout.activity_listshow, new String[] { "name", "age", "adress" }, new int[] {R.id.name,R.id.age,R.id.address}); lv=(ListView)findViewById(R.id.list_item); lv.setAdapter(simplead); //用简单适配器将数据映射到ListView上 } }
结束
