在android小部件中添加-在运行时删除视图

我必须在android小部件中删除/添加一个布局，点击按钮（按钮在小部件上）

这是我的密码

    @Override
    public void onUpdate(Context context, AppWidgetManager appWidgetManager, int[] appWidgetIds) {
        // There may be multiple widgets active, so update all of them
        final int N = appWidgetIds.length;
        for (int i = 0; i < N; i++) {
            updateAppWidget(context, appWidgetManager, appWidgetIds[i]);
        }
    }

    @Override
    public void onReceive(Context context, Intent intent) {
        super.onReceive(context, intent);

        if(intent.getAction().equals(ACTION_HIDE_BALANCE)) {
            // CODE TO CHANGE WIDGET UI

        }
    }

    static void updateAppWidget(Context context, AppWidgetManager appWidgetManager, int appWidgetId) {

        CharSequence widgetText = context.getString(R.string.appwidget_text);
        // Construct the RemoteViews object
        RemoteViews views = new RemoteViews(context.getPackageName(), R.layout.widget);

        Intent intent;
        intent = new Intent(ACTION_HIDE_BALANCE);
        PendingIntent hideBalancePendingIntent = PendingIntent.getBroadcast(context, 0, intent, PendingIntent.FLAG_UPDATE_CURRENT);
        views.setOnClickPendingIntent(R.id.action_wallet_hide_balance, hideBalancePendingIntent);

        intent = new Intent(ACTION_SHOW_BALANCE);
        PendingIntent showBalancePendingIntent = PendingIntent.getBroadcast(context, 0, intent, PendingIntent.FLAG_UPDATE_CURRENT);
        views.setOnClickPendingIntent(R.id.action_wallet_show_balance, showBalancePendingIntent);


        // Instruct the widget manager to update the widget
        appWidgetManager.updateAppWidget(appWidgetId, views);
    }
}

@覆盖
公共void onUpdate（上下文上下文，AppWidgetManager AppWidgetManager，int[]AppWidgetId）{
//可能有多个窗口小部件处于活动状态，因此请更新所有窗口小部件
final int N=appWidgetIds.length；
对于（int i=0；i

在互联网上搜索时，我发现PendingEvent技术具有onClickListener效果（已经在我的清单中添加了意图过滤器）

问题在于onRecieve（）回调：如何更改小部件UI？ 我必须删除一个类似于rootView.removeView（layoutView）的布局

提前感谢。

好的，我发现这几乎和标准视图一样简单

@Override
public void onReceive(Context context, Intent intent) {
    AppWidgetManager appWidgetManager = AppWidgetManager.getInstance(context);
    int appWidgetId = 0;

    if(intent.getAction().equals(ACTION_HIDE_BALANCE)) {
        RemoteViews views = new RemoteViews(context.getPackageName(), R.layout.root_view);
        views.removeAllViews(R.id.view_to_remove);
        appWidgetId = intent.getExtras().getInt(AppWidgetManager.EXTRA_APPWIDGET_ID);
        appWidgetManager.updateAppWidget(appWidgetId, views);
    }

    super.onReceive(context, intent);
}

显然，必须将AppWidgetManager.EXTRA_APPWIDGET_ID EXTRA附加到onClick pendingent
