android折叠listview,android – 如何在listview中展开和折叠项目

我对

android很新.我想实现一个列表视图.它包含一些列表项,当它们被单击时,它们应该展开以显示更多信息.但我无法找到办法做到这一点

这是我的activity_main.xml

xmlns:tools="http://schemas.android.com/tools"

listview。android:layout_width="match_parent"

android:layout_height="match_parent" >

android:id="@+id/listview1"

android:layout_width="match_parent"

android:layout_height="wrap_content"

android？android:layout_alignParentLeft="true"

android:clickable="True"

android:layout_alignParentTop="true"

android:divider="#000"

android:dividerHeight="0.5dp"

android:padding="7dp" >

安卓怎样在listview赋值，listview.xml

android:layout_width="match_parent"

android:layout_height="match_parent" >

android:id="@+id/textView1"

安卓listview用法，android:layout_width="wrap_content"

android:layout_height="wrap_content"

android:layout_alignParentLeft="true"

android:layout_alignParentTop="true"

android:layout_marginLeft="23dp"

android:layout_marginTop="20dp"

androidviewpager轮播，android:drawableLeft="@drawable/expand_icon"

android:drawablePadding="10dp"

android:textAppearance="?android:attr/textAppearanceLarge" />

android:id="@+id/textView2"

android:layout_width="wrap_content"

listview adapter、android:layout_height="wrap_content"

android:layout_alignLeft="@+id/textView1"

android:layout_below="@+id/textView1"

android:visibility="gone" />

我想填充textview2以显示更多信息.下面是我的main_activity.java

public class MainActivity extends Activity {

android tablelayout、ListView list;

String[] titles;

String[] desc;

@Override

protected void onCreate(Bundle savedInstanceState) {

super.onCreate(savedInstanceState);

listview界面？setContentView(R.layout.activity_main);

Resources res = getResources();

list = (ListView) findViewById(R.id.listview1);

titles = res.getStringArray(R.array.text_info);

desc = res.getStringArray(R.array.text_desc);

ArrayAdapter adapter = new ArrayAdapter(this,

android viewpager。R.layout.listview, R.id.textView1, titles);

list.setAdapter(adapter);

}

strings.xml中
