我创建了一个键盘锁小部件,其中包含一个按钮,可在单击时使用随机数提升textview。它在主屏幕上正常工作,但在锁定屏幕上(android 4.2.2)它(s按钮)工作时,我将它添加到我的锁屏小部件,但当我关闭屏幕并返回;它(s按钮)不起作用!!

Widget.java

public class Widget extends AppWidgetProvider {

    @Override
    public void onUpdate(Context context, AppWidgetManager appWidgetManager, int[] appWidgetIds) {
        Timer timer = new Timer();
        timer.scheduleAtFixedRate(new MyTime(context, appWidgetManager), 1, 50000);
    }

    class MyTime extends TimerTask {
        RemoteViews remoteViews;
        AppWidgetManager appWidgetManager;
        ComponentName thisWidget;
        Context context;

    public MyTime(Context context, AppWidgetManager appWidgetManager) {
        this.appWidgetManager = appWidgetManager;
        remoteViews = new RemoteViews(context.getPackageName(), R.layout.widget);
        thisWidget = new ComponentName(context, Widget.class);
        this.context=context;
    }

    @Override
    public void run() {
        Intent configIntent = new Intent(context, WidgetReceive.class);
        configIntent.setAction("updateTextView");
        PendingIntent configPendingIntent = PendingIntent.getBroadcast(context, 0, configIntent, 0);
        remoteViews.setOnClickPendingIntent(R.id.button1, configPendingIntent);
        remoteViews.setTextViewText(R.id.widget_textview, String.valueOf(new Random().nextInt(100)));
        appWidgetManager.updateAppWidget(thisWidget, remoteViews);
    }

    }


}

WidgetReceive.java

public class WidgetReceive extends BroadcastReceiver{

    @Override
    public void onReceive(Context context, Intent intent) {
        AppWidgetManager appWidgetManager = AppWidgetManager.getInstance(context);
        RemoteViews remoteViews = new RemoteViews(context.getPackageName(), R.layout.widget);
        ComponentName thisWidget = new ComponentName(context, Widget.class);

        if(intent.getAction().equals("updateTextView")){
        remoteViews.setTextViewText(R.id.widget_textview, String.valueOf(new Random().nextInt(100)));
        appWidgetManager.updateAppWidget(thisWidget, remoteViews);
        }
    }

}

的AndroidManifest.xml

 <receiver android:name=".Widget" android:label="@string/app_name">
        <intent-filter> <action android:name="android.appwidget.action.APPWIDGET_UPDATE"/> 
        </intent-filter>
        <meta-data android:name="android.appwidget.provider" android:resource="@xml/hello_widget_provider" />
    </receiver>   
    <receiver android:name=".WidgetReceive">
         <intent-filter>
             <action android:name="updateTextView"/> 
        </intent-filter>
    </receiver>

问题可能是以下一行

remoteViews.setOnClickPendingIntent(R.id.button1, configPendingIntent);
WidgetReceive.onReceive(...)

缺少

使用RemoteViews对象更新应用小部件时,您必须每次都创建小部件的所有内容,包括侦听器。
