怎么知道点击小部件ID？ [英] How to know clicked widget id?

问题描述

我实现了一个小工具与的ImageButton 和的TextView 。这的ImageButton 推出的活动时，它的点击。这活动什么用户写上的活动的EditText 更新微件文本。现在的问题是，我只知道如何让IDS是这样的：

I have implemented a widget with an ImageButton and a TextView. That ImageButton launch an activity when its clicked. This activity updates the widget text with what the user writes on the activity EditText. Now the problem is that I only know how to get the ids like this:

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);
    }

这code将显着改变所有的ID的数据，因为它在为。反正是有，我可以过去的点击为widgetid与我的意图，这样我就可以消除为？这是我的widgetProvider：

This code will obviously change the data of all the ids, since its inside a for. Is there anyway that I can past the clicked widgetId with my intent, so I can eliminate that for? This is my 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);
    }
}

对于一个运行的例子看看我的code的<一个href="https://bitbucket.org/jholetzeck/minicallwidget-android/src/8e6c325f299775674ec530abb64ee39302cf89ff/src/de/holetzeck/minicallwidget/MiniCallWidget.java?at=default">MiniCallWidget线97和169。

For a running example have a look at my code for MiniCallWidget lines 97 and 169.
