这里写图片描述
    在layout下建立list-item.xml代码如下<LinearLayout android:orientation="horizontal" android:layout_height="fill_parent" android:layout_width="fill_parent" xmlns:android="http://schemas.android.com/apk/res/android"><!-- 左边图片 --><ImageView android:layout_height="48dp" android:layout_width="48dp" android:padding="10dp" android:id="@+id/photo"/><!-- 右边布局 --><LinearLayout android:orientation="vertical" android:layout_height="wrap_content" android:layout_width="fill_parent"><!-- 上边布局 --><LinearLayout android:orientation="horizontal" android:layout_height="wrap_content" android:layout_width="fill_parent"><!-- 发布人 --><TextView android:layout_height="wrap_content" android:layout_width="wrap_content" android:id="@+id/name"/><!-- 发布时间 --><TextView android:layout_height="wrap_content" android:layout_width="fill_parent" android:id="@+id/publish" android:gravity="right"/></LinearLayout><!-- 下边发布内容 --><TextView android:layout_height="wrap_content" android:layout_width="wrap_content" android:id="@+id/content"/></LinearLayout></LinearLayout>          自定义标题栏。1.<?xml version="1.0" encoding="UTF-8"?><resources xmlns:android="http://schemas.android.com/apk/res/android">-<style name="myTitleBg"><item name="android:background">#FF0000</item></style>-<style name="myTheme" parent="android:Theme"><item name="android:windowNoTitle">false</item><item name="android:windowTitleSize">30dp</item><item name="android:background">#FF0000</item><itemname="android:windowTitleBackgroundStyle">@style/myTitleBg</item></style></resources>2.修改AndroidManifest.xml文件android:theme="@style/myTheme"代码如下：MainActivity.javapackage cn.bzu.listview03;import java.util.ArrayList;import java.util.HashMap;import java.util.List;import java.util.Map;import android.os.Bundle;import android.app.Activity;import android.view.Menu;import android.view.View;import android.widget.AdapterView;import android.widget.ListView;import android.widget.SimpleAdapter;import android.widget.AdapterView.OnItemClickListener;import android.widget.Toast;//第一步：extends Activitypublic class MainActivity extends Activity {// 第二步：定义数据集合    List<Map<String, ?>> data;

       listView=(ListView) this.findViewById(R.id.listView);        listView.setAdapter(adapter);        listView.setOnItemClickListener(new ListClickHandler());}//第四步：添加单击事件    private class ListClickHandler implements OnItemClickListener{    @Override   public void onItemClick(AdapterView<?> adapterView, View view, int position,long id) {            Map<String, String> item=(Map<String, String>) data.get(position);
