一个Android应用向Home screen添加多个Widget

如Twitter客户端或者HTC的日历应用，可以添加大小不同的Widget。此疑问。原来如此简单，只是我原来不会罢了。首先在AndroidManifest.xml中太假多个接收器：Xml代码

<receiver android:name="com.jftt.widget.MyWidgetProvider1" android:label="天气 4 x 1">
<meta-data android:name="android.appwidget.provider"
android:resource="@xml/my_widget1" />
<intent-filter>
<action android:name="android.appwidget.action.APPWIDGET_UPDATE" />
</intent-filter>
</receiver>
<receiver android:name="com.jftt.widget.MyWidgetProvider" android:label="全部 4 x 2">
<meta-data android:name="android.appwidget.provider"
android:resource="@xml/my_widget" />
<intent-filter>
<action android:name="android.appwidget.action.APPWIDGET_UPDATE" />
</intent-filter>
</receiver>
<receiver android:name="com.jftt.widget.MyWidgetProvider2" android:label="步数 4 x 1">
<meta-data android:name="android.appwidget.provider"
android:resource="@xml/my_widget2" />
<intent-filter>
<action android:name="android.appwidget.action.APPWIDGET_UPDATE" />
</intent-filter>
</receiver>

CreateWidget.java文件内容如下：Java代码

package com.jftt.activity;
import android.app.Activity;
import android.appwidget.AppWidgetManager;
import android.content.Intent;
import android.os.Bundle;
import android.util.Log;
import com.jftt.widget.R;
public class CreateWidget extends Activity {
private static final String TAG = "CreateWidget";
int mAppWidgetId;
@Override
protected void onCreate（Bundle savedInstanceState） {
super.onCreate（savedInstanceState）;
Log.i（TAG, " on WidgetConf ... "）;
setResult（RESULT_CANCELED）;
// Find the widget id from the intent.
Intent intent = getIntent（）;
Bundle extras = intent.getExtras（）;
if （extras ！= null） {
mAppWidgetId = extras.getInt（AppWidgetManager.EXTRA_APPWIDGET_ID, AppWidgetManager.INVALID_APPWIDGET_ID）;
}
// If they gave us an intent without the widget id, just bail.
if （mAppWidgetId == AppWidgetManager.INVALID_APPWIDGET_ID） {
finish（）;
}
// return OK
Intent resultValue = new Intent（）;
resultValue.putExtra（AppWidgetManager.EXTRA_APPWIDGET_ID, mAppWidgetId）;
setResult（RESULT_OK, resultValue）;
finish（）;
}
}
