简约而不简单——Android SimpleAdapter

列表(ListView)、表格(GridView),这在手机应用上面肯定是少不了的,怎样实现比较复杂一点的界面呢,先看一下我的效果图。

这样布局的情况是最基本的,也是最常用的,网上关于这样的布局有多种版本的实现方法,但是有很多需要自己实现Adapter,那样子是比较复杂而且没有必要的,因为我们有简约而不简单的SimpleAdapter。

1. ListView

SimpleAdapter的核心代码:

		for (int i = 0; i < 10; i++) {

			Map<String, Object> map = new HashMap<String, Object>();

			map.put("PIC", R.drawable.pic);

			map.put("TITLE", "Test Title");

			map.put("CONTENT", "Test Content");

			contents.add(map);

		}

		SimpleAdapter adapter = new SimpleAdapter(this,

				(List<Map<String, Object>>) contents, R.layout.listitem,

				new String[] { "PIC", "TITLE", "CONTENT" }, new int[] {

						R.id.listitem_pic, R.id.listitem_title,

						R.id.listitem_content });



		listView.setAdapter(adapter);

 

listitem的Layout:

<?xml version="1.0" encoding="utf-8"?>



<RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android"

	android:layout_width="fill_parent" android:layout_height="?android:attr/listPreferredItemHeight">

	<ImageView android:id="@+id/listitem_pic"

		android:layout_width="wrap_content" android:layout_height="fill_parent"

		android:layout_alignParentTop="true" android:layout_alignParentBottom="true"

		android:src="@drawable/pic" android:adjustViewBounds="true"

		android:padding="2dip" />

	<TextView android:id="@+id/listitem_title"

		android:layout_width="wrap_content" android:layout_height="wrap_content"

		android:layout_toRightOf="@+id/listitem_pic"

		android:layout_alignParentRight="true" android:layout_alignParentTop="true"

		android:layout_above="@+id/listitem_content"

		android:layout_alignWithParentIfMissing="true" android:gravity="center_vertical"

		android:text="@+id/listitem_title" android:textSize="22px" />

	<TextView android:id="@+id/listitem_content"

		android:layout_width="fill_parent" android:layout_height="wrap_content"

		android:layout_toRightOf="@+id/listitem_pic"

		android:layout_alignParentBottom="true"

		android:layout_alignParentRight="true" android:singleLine="true"

		android:ellipsize="marquee" android:text="@+id/item_content"

		android:textSize="14px" />

</RelativeLayout>

 

 

2. GridView

SimpleAdapter的核心代码:

		for (int i = 0; i < 10; i++) {

			Map<String, Object> map = new HashMap<String, Object>();

			map.put("PIC", R.drawable.pic);

			map.put("TITLE", "Test Title");

			contents.add(map);

		}

		SimpleAdapter adapter = new SimpleAdapter(this,

				(List<Map<String, Object>>) contents, R.layout.griditem,

				new String[] { "PIC", "TITLE" }, new int[] { R.id.griditem_pic,

						R.id.griditem_title, });



		gridView.setAdapter(adapter);


griditem的Layout:

<?xml version="1.0" encoding="utf-8"?>

<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"

	android:layout_height="fill_parent" android:layout_width="fill_parent"

	android:orientation="vertical">

	<ImageView android:id="@+id/griditem_pic"

		android:layout_width="wrap_content" android:layout_height="wrap_content"

		android:layout_gravity="center_horizontal">

	</ImageView>

	<TextView android:id="@+id/griditem_title"

		android:layout_width="wrap_content" android:layout_height="wrap_content"

		android:layout_gravity="center_horizontal" android:text="test">

	</TextView>

</LinearLayout>
