仿新浪微博栏目随便看看

最近学习了ListView组件下面分享一下：

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>

//第一步：extends Activity

// 第二步：定义数据集合

List<Map<String, ?>> data;

// 第三步：创建SimpleAdapter绑定数据

listView.setAdapter(adapter);

}

//第四步：添加单击事件

private class ListClickHandler implements OnItemClickListener{

long id) {
