模拟新浪微博随便看栏目


刚刚学习了ListView组件虽然还有很多不足的地方但是我还是想分享给大家：

测试图如下：



代码如下：

activity_main.xml
<?xml version="1.0"?>
-<LinearLayout android:layout_height="fill_parent" android:layout_width="fill_parent" xmlns:tools="http://schemas.android.com/tools" xmlns:android="http://schemas.android.com/apk/res/android">
<ListView android:layout_height="fill_parent" android:layout_width="fill_parent" android:id="@+id/listView"/>
</LinearLayout>

list_item.xml
<?xml version="1.0" encoding="UTF-8"?>
-<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>



MainActivity.java
package 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.widget.ListView;
import android.widget.SimpleAdapter;
import android.widget.AdapterView.OnItemClickListener;
import android.widget.Toast;
//第一步：extends Activity
public class MainActivity extends Activity {
//
4000
第二步：定义数据集合
List<Map<String, ?>> data;
ListView listView;
@Override
public void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);
data = getData();
// 第三步：创建SimpleAdapter绑定数据
SimpleAdapter adapter = new SimpleAdapter(this, data,
R.layout.list_item, new String[] { "photo", "name", "publish",
"content" }, new int[] { R.id.photo, R.id.name,
R.id.publish, R.id.content });
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);
Toast.makeText(MainActivity.this, item.get("name").toString(), Toast.LENGTH_LONG).show();
}

}
private List<Map<String, ?>> getData() {
List<Map<String, ?>> data = new ArrayList<Map<String, ?>>();
Map<String, Object> item = new HashMap<String, Object>();
item.put("photo", R.drawable.p1);
