实现自定义布局的Notification

上一节中，我们实现了自己的notification，相信大家都有了一些认识，在最后也接受了利用RemoteView来实现自定义布局的notification，这里就来举一个示例，方便理解。

第一步：新建一个工程，命名为cusNotification；

第二步：新建一个布局文件(即自定义的notification的布局文件:custom_notification.xml，内容如下：

<?xml version="1.0" encoding="utf-8"?>
<RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android"
    android:layout_width="match_parent"
    android:layout_height="match_parent" >

    <ImageView
        android:id="@+id/image"
        android:layout_width="wrap_content"
        android:layout_height="fill_parent"
        android:layout_alignParentLeft="true"
        android:layout_marginRight="10dp"
        android:contentDescription="@string/Image" />

    <TextView
        android:id="@+id/title"
        android:layout_width="wrap_content"
        android:layout_height="wrap_content"
        android:layout_toRightOf="@id/image"
        style="@style/NotificationTitle" />

    <TextView
        android:id="@+id/text"
        android:layout_width="wrap_content"
        android:layout_height="wrap_content"
        android:layout_toRightOf="@id/image"
        android:layout_below="@id/title"
        style="@style/NotificationText" />

</RelativeLayout>
<?xml version="1.0" encoding="utf-8"?>
<RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android"
    android:layout_width="match_parent"
    android:layout_height="match_parent" >

<ImageView
     android:id="@+id/image"
        android:layout_width="wrap_content"
        android:layout_height="fill_parent"
        android:layout_alignParentLeft="true"
        android:layout_marginRight="10dp"
        android:contentDescription="@string/Image" />

    <TextView
        android:id="@+id/title"
        android:layout_width="wrap_content"
        android:layout_height="wrap_content"
        android:layout_toRightOf="@id/image"
        style="@style/NotificationTitle" />

    <TextView
        android:id="@+id/text"
        android:layout_width="wrap_content"
        android:layout_height="wrap_content"
        android:layout_toRightOf="@id/image"
        android:layout_below="@id/title"
        style="@style/NotificationText" />

</RelativeLayout>
          第三步：新建上面布局文件中引用到的styyes.xml文件，代码如下：

<?xml version="1.0" encoding="utf-8"?>
<resources>
    <style name="NotificationText" parent="android:TextAppearance.StatusBar.EventContent" />
    <style name="NotificationTitle" parent="android:TextAppearance.StatusBar.EventContent.Title" />
</resources>
<?xml version="1.0" encoding="utf-8"?>
<resources>
    <style name="NotificationText" parent="android:TextAppearance.StatusBar.EventContent" />
    <style name="NotificationTitle" parent="android:TextAppearance.StatusBar.EventContent.Title" />
</resources>
       第四步：修改java源文件，代码如下：

public class CusNotificationActivity extends Activity {
    private static final int CUSTOM_VIEW_ID = 1;
    /** Called when the activity is first created. */
    @Override
    public void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.main);

        //Notification notification = new Notification();
        int icon = R.drawable.ic_launcher;
        CharSequence tickerText = "Notification01";
        long when = System.currentTimeMillis();

        Notification notification = new Notification(icon, tickerText, when);

        RemoteViews contentView = new RemoteViews(getPackageName(), R.layout.custom_notification);
        contentView.setImageViewResource(R.id.image, R.drawable.notification_image);
        contentView.setTextViewText(R.id.title, "Custom notification");
        contentView.setTextViewText(R.id.text, "This is a custom layout");
        notification.contentView = contentView;

        Intent notificationIntent = new Intent(this, CusNotificationActivity.class);
        PendingIntent contentIntent
