Android：从主屏幕小部件拨打电话

Question

我有一个小部件，我希望它在用户单击该小部件时向特定号码拨打电话。我该怎么做？请帮忙。

Answer 1

我能够使用以下代码让它工作：

 @Override
 public void onUpdate(Context context, AppWidgetManager appWidgetManager, int[] appWidgetIds) {
    Log.d(LOG_TAG, "onUpdate(): ");
    for (int appWidgetId : appWidgetIds) {

        Intent callIntent = new Intent(Intent.ACTION_CALL);
        callIntent.setData(Uri.parse("tel:"+number));
        PendingIntent pendingIntent = PendingIntent.getActivity(context, 0, callIntent, 0);

        // Get the layout for the App Widget and attach an on-click listener to the button
        RemoteViews views = new RemoteViews(context.getPackageName(), R.layout.caller);
        views.setOnClickPendingIntent(R.id.callButton, pendingIntent);

        // Tell the AppWidgetManager to perform an update on the current App Widget
        appWidgetManager.updateAppWidget(appWidgetId, views);
    }
}

Answer 2

    public static Intent newPhoneCallIntent(String phoneNumber){
     Intent callintent = new Intent(Intent.ACTION_DIAL);
     callintent.setData(Uri.parse("tel:"+phoneNumber));
     return callintent;
    }
    startActivity(newPhoneCallIntent("5555555555"));
