Android中的ListView实现图片文字和按钮
实现效果图：
布局文件：
vlist2.xml
?
<?xml version="1.0" encoding="utf-8"?>
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:orientation="horizontal"
android:layout_width="fill_parent"
android:layout_height="fill_parent">
<ImageView android:id="@+id/img"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:layout_margin="5px"/>
<LinearLayout android:orientation="vertical"
android:layout_width="wrap_content"
android:layout_height="wrap_content">
<TextView android:id="@+id/title"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:textColor="#FFFFFFFF"
android:textSize="22px" />
<TextView android:id="@+id/info"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:textColor="#FFFFFFFF"
android:textSize="13px" />
</LinearLayout>
<Button android:id="@+id/view_btn"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:text="@string/s_view_btn"
android:layout_gravity="bottom|right" />
</LinearLayout>

public class MyListView4
extends ListActivity
{
private List<Map<String,
Object>> mData;
@Override
public void onCreate(Bundle
savedInstanceState) {
super.onCreate(savedInstanceState);

= getData();
