Android 应用开发札记 - 列表（ListView）& SimpleAdapter

1. 新建一Layout XML文件，如下图：

在面板拖拽，更改相关属性，

res/list_view.xml清单如下：

<?xml version="1.0" encoding="utf-8"?><LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"    android:layout_width="match_parent"    android:layout_height="match_parent"    android:orientation="vertical" >        <ListView        android:id="@+id/listView01"        android:layout_width="fill_parent"        android:layout_height="wrap_content"        android:layout_gravity="center"         android:divider="@null"         android:dividerHeight="0dp" /></LinearLayout>

2. 新建ListView中行的Layout XML

res/list_row.xml清单如下：

<?xml version="1.0" encoding="utf-8"?><LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"    android:layout_width="wrap_content"    android:layout_height="wrap_content"    android:orientation="horizontal" >        <ImageView android:id="@+id/imgIcon"        android:layout_width="wrap_content"        android:layout_height="wrap_content"        android:layout_margin="8dp" />        <LinearLayout android:layout_width="fill_parent"         android:layout_height="wrap_content"        android:layout_marginBottom="5dp"        android:layout_marginTop="5dp"        android:orientation="vertical"        android:paddingLeft="0px"        android:paddingRight="5dp" >                <RelativeLayout android:layout_width="fill_parent"            android:layout_height="wrap_content" >                        <TextView android:id="@+id/title01"                android:layout_width="wrap_content"                android:layout_height="wrap_content"                android:layout_alignParentLeft="true"                android:textColor="@color/red"                android:textSize="@dimen/font_size24" />                    </RelativeLayout>                <TextView android:id="@+id/desText"            android:layout_width="wrap_content"            android:layout_height="wrap_content"            android:layout_marginTop="4dp"            android:textColor="@color/blue"            android:textSize="@dimen/font_size20"/>            </LinearLayout>    </LinearLayout>

3. 编写代码

(1) 获取各行数据

(2) 新建SimpleAdapter实例

(3) ListView绑定SimpleAdapter

代码如下：

ListView listView = (ListView) findViewById(R.id.listView01);								List<Map<String, Object>> data = getSampleData();				SimpleAdapter sAdapter = new SimpleAdapter(						MainActivity.this, 						data, 						R.layout.list_row,						new String[] {							"imgIcon",							"title01",							"desText"						},						new int[] {							R.id.imgIcon,							R.id.title01,							R.id.desText						}				);								listView.setAdapter(sAdapter);

运行效果：
