我正在构建一个具有多个按钮的小部件,每个按钮都将自己的意图发送给广播接收器.广播接收器假设基于按下哪个按钮显示Toast消息.代码目前看起来像这样:

public class WidgetProvider extends AppWidgetProvider {

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

        ComponentName thisWidget = new ComponentName(context, WidgetProvider.class);
        int[] allWidgetIds = appWidgetManager.getAppWidgetIds(thisWidget);
        for (int widgetId : allWidgetIds) {
            RemoteViews remoteViews = new RemoteViews(context.getPackageName(), R.layout.widget_layout);

            SharedPreferences prefs = PreferenceManager.getDefaultSharedPreferences(context);

            // Set the text of the buttons
            remoteViews.setTextViewText(R.id.widgetPreset1Button, prefs.getString("widget1", "Not set"));
            remoteViews.setTextViewText(R.id.widgetPreset2Button, prefs.getString("widget2", "Not set"));
            remoteViews.setTextViewText(R.id.widgetPreset3Button, prefs.getString("widget3", "Not set"));
            remoteViews.setTextViewText(R.id.widgetPreset4Button, prefs.getString("widget4", "Not set"));

            // Register the buttons with an OnClick event
            Intent intent1 = new Intent("myapp.SendWidgetPreset");
            intent1.putExtra("Widget", 1); …
