怎么知道点击控件ID？(How to know clicked widget id?)

我实现了一个widget与ImageButton和TextView 。这ImageButton发起activity的点击时。此activity更新什么用户在活动写入插件文本EditText 。现在的问题是，我只知道如何获得这样的标识：

for (int widgetId : allWidgetIds) {
        // Create some random data
        int number = (new Random().nextInt(100));

        RemoteViews remoteViews = new RemoteViews(getApplicationContext()
                .getPackageName(), R.layout.widget_layout);
        Log.w("WidgetExample", String.valueOf(number));

        //Here I should set text from edit text, but I'm using a random for testing.

        remoteViews.setTextViewText(R.id.textView1,
                "Random: " + String.valueOf(number));

        appWidgetManager.updateAppWidget(widgetId, remoteViews);
    }

此代码将明显改变所有的ID的数据，因为它里面for 。反正是有，我可以过去和我的意图的点击为widgetid，这样我就可以消除for ？这是我的widgetProvider：

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

    // Get all ids
    ComponentName thisWidget = new ComponentName(context, Widget.class);
    allWidgetIds = appWidgetManager.getAppWidgetIds(thisWidget);
    for (int widgetId : allWidgetIds) {

        Intent i = new Intent(context, WidgetSetup.class);
        i.putExtra(AppWidgetManager.EXTRA_APPWIDGET_IDS, allWidgetIds);
        i.setFlags(i.FLAG_ACTIVITY_NEW_TASK);
        context.startActivity(i);

        // Create some random data
        int number = (new Random().nextInt(100));

        RemoteViews remoteViews = new RemoteViews(context.getPackageName(),
                R.layout.widget_layout);
        // Set the text
        remoteViews.setTextViewText(R.id.textView1, String.valueOf(number));

        Intent active = new Intent(context, Widget.class);
        active.setAction(ACTION_WIDGET_REFRESH);
        PendingIntent actionPendingIntent = PendingIntent.getBroadcast(context, 0, active, 0);
        remoteViews.setOnClickPendingIntent(R.id.imageButton1, actionPendingIntent);

        active = new Intent(context, Widget.class);
        active.setAction(ACTION_WIDGET_SETTINGS);
        actionPendingIntent = PendingIntent.getBroadcast(context, 0, active, 0);
        remoteViews.setOnClickPendingIntent(R.id.imageButton2, actionPendingIntent);

        appWidgetManager.updateAppWidget(appWidgetIds, remoteViews);
    }
}

@Override
public void onReceive(Context context, Intent intent) {
    if (intent.getAction().equals(ACTION_WIDGET_REFRESH)) {
        //Log.i("onReceive", ACTION_WIDGET_REFRESH);

        Intent i = new Intent(context, MainActivity.class);
        i.setFlags(i.FLAG_ACTIVITY_NEW_TASK);
        context.startActivity(i);

    } else if (intent.getAction().equals(ACTION_WIDGET_SETTINGS)) {
        //Log.i("onReceive", AppWidgetManager.EXTRA_APPWIDGET_ID);



        Intent i = new Intent(context, WidgetSetup.class);
        i.putExtra(AppWidgetManager.EXTRA_APPWIDGET_IDS, allWidgetIds);

        //Here I tried to pass the widgetID with no luck.
        //i.putExtra(pass widget id?);

        i.setFlags(i.FLAG_ACTIVITY_NEW_TASK);
        context.startActivity(i);

    } else {
        super.onReceive(context, intent);
    }
}

谢谢

对于一个正在运行的例子看看我的代码为MiniCallWidget线97和169。

额外添加到您启动的onClick，并在创建循环，指定当前控件正在设置ID的意图。

然后检索在接收活动的群众演员的ID，并把它传递回来时，你就大功告成了。然后使用返回的ID进行更改只有一个小部件。

您可以通过具有这样做的if-else也检查，告诉你是否要更新只有一个小部件的标志。
