• Topic: ListView of the User interface (list view)
  -listview and Textview,button are the same way of defining and displaying, so they are no longer repeated. But the ListView in Android development often fits some adapters to display, so we have to learn to focus on the various adaptations of the ListView.

Arrayadapter adaptation display for ListView

<?xml version= "1.0" encoding= "Utf-8"?><linearlayout xmlns:android="Http://schemas.android.com/apk/res/android"  Android:orientation="vertical"android:layout_width="Fill_parent"android: Layout_height="Fill_parent" >                <ListViewandroid:id="@+id/listview"android:layout_width= "Fill_parent" android:layout_height="wrap_content" />                         </linearlayout>

Mainactivity.java Source code:

Importandroid.app.Activity;ImportAndroid.os.Bundle;ImportAndroid.widget.ArrayAdapter;ImportAndroid.widget.ListView; Public  class mainactivity extends Activity {    PrivateListView ListView; String[] str={"AA","BB","CC","DD","ee"};@Override    protected void onCreate(Bundle savedinstancestate) {Super. OnCreate (Savedinstancestate);        Setcontentview (R.layout.activity_main);        ListView = (ListView) Findviewbyid (R.id.listview); arrayadapter<string> adapter =NewArrayadapter<string> ( ThisAndroid.        R.layout.simple_list_item_1, str);    Listview.setadapter (adapter); }}

Operation Result:
