我能够使用此代码使其工作:
@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);
}
}
【讨论】:
onUpdate()。
public static Intent newPhoneCallIntent(String phoneNumber){
Intent callintent = new Intent(Intent.ACTION_DIAL);
callintent.setData(Uri.parse("tel:"+phoneNumber));
return callintent;
}
startActivity(newPhoneCallIntent("5555555555"));
【讨论】:
onUpdate() 函数中?
startActivity() 抛出错误 - The method startActivity(Intent) is undefined for the type Widget
