1.ListView 简单用法

<?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"
    android:layout_width="match_parent"
    android:layout_height="match_parent">

     <ListView android:id="@+id/m_listView1"
         android:layout_width="match_parent"
         android:layout_height="match_parent"/>

</LinearLayout>

public class MainActivity extends AppCompatActivity {

    private List<String> listDatas = Arrays.asList("Apple", "Banana", "Orange", "Watermelon",
                "Pear", "Grape", "Pineapple", "Strawberry", "Cherry", "Mango"
                , "Apple", "Banana"
                , "Orange", "Watermelon"
                , "Pear", "Grape",
                "Pineapple"
                , "Strawberry", "Cherry", "Mango");

    @Override
    protected void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.activity_main);
        //ArrayAdapter的构造函数传入3个数据：1是Context 传入当前的上下文,2是ListView子项布局的ID,3是要适配的数据
        //android.R.layout.simple_list_item_1,listDatas是内置的ListViewItem
        ArrayAdapter<String> dapter = new ArrayAdapter<String>(MainActivity.this, android.R.layout.simple_list_item_1,listDatas);
        ListView listView =  findViewById(R.id.m_listView1);
        listView.setAdapter(dapter);

    }
}

2.自定义ListViewItem
