我正在尝试设置一个包含两个按钮的小部件。单击小部件应引发主要活动。单击两个按钮之一应该执行其他操作。

我已经尝试按照Android 小部件按钮处理多个按钮单击 Android 小部件但没有骰子上描述的步骤进行操作。我不知道我做错了什么。

我的清单的相关部分:

<receiver android:name="WidgetProvider" android:icon="@drawable/icon" android:label="Radio Podcastellano">
      <intent-filter>
          <action android:name="android.appwidget.action.APPWIDGET_UPDATE" />
          <action android:name="es.radiopodcastellano.player.WidgetProvider.ACTION_UPDATEINFO"/>
          <action android:name="es.radiopodcastellano.player.WidgetProvider.ACTION_REFRESH"/>
          <action android:name="es.radiopodcastellano.player.WidgetProvider.ACTION_PLAYPAUSE"/>
          <action android:name="es.radiopodcastellano.player.WidgetProvider.ACTION_SHOWMAIN" />
      </intent-filter>
      <meta-data android:name="android.appwidget.provider" android:resource="@xml/widget_info" />
    </receiver>

现在,WidgetProvider 类本身:

public class WidgetProvider extends AppWidgetProvider {

public static String ACTION_PLAYPAUSE="ActionReveicerPlayPause";
public static String ACTION_UPDATEINFO="ActionReceiverUpdateInfo";
public static String ACTION_REFRESH="ActionReceiverRefresh";
public static String ACTION_SHOWMAIN="ActionShowMain";

@Override
public void onReceive(Context ctxt, Intent intent) {
    if (intent.getAction().equals(ACTION_REFRESH)) {
        Log.d("RPod_Widget", ACTION_REFRESH);
    } else if (intent.getAction().equals(ACTION_UPDATEINFO)) {
        Log.d("RPod_Widget", ACTION_UPDATEINFO);
    } else if (intent.getAction().equals(ACTION_PLAYPAUSE)) {
        Log.d("RPod_Widget", ACTION_PLAYPAUSE);
    } else if (intent.getAction().equals(ACTION_SHOWMAIN)) {
        Log.d("RPod_Widget", ACTION_SHOWMAIN);
    } else {
        Log.d("RPod_Widget", intent.getAction());
        super.onReceive(ctxt, intent);
    }
}

@Override
public void onUpdate(Context context, AppWidgetManager appWidgetManager, int[] appWidgetIds) {

    Log.d("RPod_Widget","Action: onUpdate");

    RemoteViews remoteViews = new RemoteViews(context.getPackageName(), R.layout.widget);

    Intent active = new Intent(context, MainActivity.class);
    active.setAction(ACTION_SHOWMAIN);
    PendingIntent actionPendingIntent = PendingIntent.getActivity(context, 234, active, 0);
    remoteViews.setOnClickPendingIntent(R.id.widgetLayout, actionPendingIntent);

    Intent active2 = new Intent(context, AppWidgetProvider.class);
    active2.setAction(ACTION_PLAYPAUSE);
    PendingIntent actionPendingIntent2 = PendingIntent.getBroadcast(context, 235, active2, 0);
    remoteViews.setOnClickPendingIntent(R.id.widgetPlayButton, actionPendingIntent2);

    Intent active3 = new Intent(context, AppWidgetProvider.class);
    active3.setAction(ACTION_UPDATEINFO);
    PendingIntent actionPendingIntent3 = PendingIntent.getBroadcast(context, 236, active3, 0);
    remoteViews.setOnClickPendingIntent(R.id.widgetReloadButton, actionPendingIntent3);

    appWidgetManager.updateAppWidget(appWidgetIds, remoteViews);


}

}

当我单击小部件布局时,会引发主要活动,但按钮会被完全忽略。我点击它们但没有效果。Logcat 上没有显示来自 onReceive 的消息,只有这个:

07-05 15:41:41.675: DEBUG/RPod_Widget(4144): Action: onUpdate
07-05 15:44:39.261: DEBUG/RPod_Widget(4198): android.appwidget.action.APPWIDGET_UPDATE
07-05 15:44:39.261: DEBUG/RPod_Widget(4198): Action: onUpdate
07-05 15:49:48.078: DEBUG/RPod_Widget(4285): android.appwidget.action.APPWIDGET_UPDATE
07-05 15:49:48.078: DEBUG/RPod_Widget(4285): Action: onUpdate

一些忠告?谢谢!

我发现了问题。一键代码:

Intent active2 = new Intent(context, AppWidgetProvider.class);
active2.setAction(ACTION_PLAYPAUSE);
PendingIntent actionPendingIntent2 = PendingIntent.getBroadcast(context, 235, active2, 0);
remoteViews.setOnClickPendingIntent(R.id.widgetPlayButton, actionPendingIntent2);

问题是我提供 AppWidgetProvider.class 作为 Intent 的参数,我应该提供 WidgetProvider.class,这是我自己的 AppWidgetProvider 实现(以前扩展 AppWidgetProvider)。因此,更正后的行:

Intent active2 = new Intent(context, WidgetProvider.class);

就这样 :)

Manifest 中的 Action 应与您在 Intent 中传递的相同

例如,

public static String ACTION_PLAYPAUSE="es.radiopodcastellano.player.WidgetProvider.ACTION_PLAYPAUSE";
