【Android学习】实现卡片式ListView

效果：

主要是设置xml文件

两种状态下的item

card_background.xml

<?xml version="1.0" encoding="utf-8"?>
<layer-list xmlns:android="http://schemas.android.com/apk/res/android" >
	<!-- 一个层叠效果,通过阴影表现出立体效果 -->
    <item><!-- 阴影效果 -->
        <shape android:shape="rectangle" >
            <solid android:color="#CABBBBBB" /><!-- 阴影的颜色 -->
 
            <corners android:radius="2dp" /><!-- 圆角 -->
        </shape>
    </item>
    <item
        android:bottom="2dp"
        android:left="0dp"
        android:right="0dp"
        android:top="0dp"><!-- 距底部2dp，漏出上面那个item，使其可以显现出阴影 -->
        <shape android:shape="rectangle" >
            <solid android:color="@android:color/white" /><!-- item颜色 -->
 
            <corners android:radius="2dp" />
        </shape>
    </item>
 
</layer-list>

card_state_pressed.xml

<?xml version="1.0" encoding="utf-8"?>
<layer-list xmlns:android="http://schemas.android.com/apk/res/android" >
 
    <item>
        <shape android:shape="rectangle" >
            <solid android:color="#ca39883d" />
 
            <corners android:radius="2dp" />
        </shape>
    </item>
    <item
        android:bottom="2dp"
        android:left="0dp"
        android:right="0dp"
        android:top="0dp">
        <shape android:shape="rectangle" >
            <solid android:color="#ca4fbb5f" />
 
            <corners android:radius="2dp" />
        </shape>
    </item>
 
</layer-list>

card_background_selector

<?xml version="1.0" encoding="utf-8"?>
<selector xmlns:android="http://schemas.android.com/apk/res/android" >
    <item android:drawable="@drawable/card_state_pressed" android:state_pressed="true" />
    <item android:drawable="@drawable/card_background" />
</selector>

list_item_card.xml

<?xml version="1.0" encoding="utf-8"?>
<FrameLayout
	xmlns:android="http://schemas.android.com/apk/res/android"
	android:layout_width="match_parent"
	android:layout_height="wrap_content"
	android:paddingLeft="15dp"
	android:paddingRight="15dp"
	android:descendantFocusability="beforeDescendants"><!-- 为突出卡片效果，需设置左右padding,上下通过listView的divider设置 -->
 
	<LinearLayout
		android:orientation="vertical"
		android:layout_width="match_parent"
		android:layout_height="wrap_content"
		android:paddingLeft="15dp"
		android:paddingTop="15dp"
		android:paddingBottom="15dp"
		android:paddingRight="15dp"
		android:background="@drawable/card_background_selector"
		android:descendantFocusability="afterDescendants"><!-- 给每个item增加background -->
 
		<TextView
			android:id="@+id/line1"
			android:layout_width="wrap_content"
			android:layout_height="wrap_content"
			android:text="Text"/>
 
	</LinearLayout>
</FrameLayout>

MainActivity.java

package com.example.cardstylelistview;
 
import android.app.Activity;
import android.os.Bundle;
import android.view.View;
import android.widget.ArrayAdapter;
import android.widget.ListView;
 
public class MainActivity extends Activity
{
	private ListView listView;
 
	private static final String[] data = { "北京", "上海", "武汉", "广州", "西安", "南京", "合肥","上海", "武汉", "广州", "西安", "南京", "合肥" };
 
	@Override
	public void onCreate(Bundle savedInstanceState)
	{
		super.onCreate(savedInstanceState);
		setContentView(R.layout.activity_main);
		listView = (ListView) findViewById(R.id.card_listView);
		/*添加头和尾*/
		listView.addHeaderView(new View(this));
		listView.addFooterView(new View(this));
 
		listView.setAdapter(new ArrayAdapter<String>(this, R.layout.list_item_card, R.id.line1, data));
 
	}
}

这样 卡片ListView就做好了
