Using a final variable obviously won’t work (since it can only be assigned once, at declaration time). So-called “global” variables are usually a code smell (especially when they become part of an Activity class, which is usually where AlertDialogs are created). The cleaner solution is to cast the DialogInterface object to an AlertDialog and then … Read more
define what follows in the styles.xml file <style name=”CustomDialog” parent=”android:Theme.Dialog”> <item name=”android:windowIsTranslucent”>true</item> <item name=”android:windowBackground”>@android:color/transparent</item> </style> and pass it as argument to the AlertDialog constructor AlertDialog.Builder imageDialog = new AlertDialog.Builder(SubProducts.this, R.style.CustomDialog); Or programmatically, through the Dialog instance you can call myDialog.getWindow().setBackgroundDrawable(new ColorDrawable(Color.TRANSPARENT))
You have to wrap the content inside another Widget (preferably Stateless). Example: Change From: import ‘package:flutter/material.dart’; void main() { runApp(new MyApp()); } class MyApp extends StatelessWidget { @override Widget build(BuildContext context) { return MaterialApp( title: ‘Trial’, home: Scaffold( appBar: AppBar(title: Text(‘List scroll’)), body: Container( child: Text(“Hello world”), ))); } } to this: import ‘dart:async’; import … Read more
I know this is an old post, but i just came across it, and found that this solution seems at bit more simple that whats been posted here. You can just do like this: In your onClick() handler on the dialog positive button, add the following code: ListView lw = ((AlertDialog)dialog).getListView(); Object checkedItem = lw.getAdapter().getItem(lw.getCheckedItemPosition()); … Read more
final AlertDialog.Builder alert = new AlertDialog.Builder(thisActivity); final EditText input = new EditText(thisActivity); input.setSingleLine(); FrameLayout container = new FrameLayout(thisActivity); FrameLayout.LayoutParams params = new FrameLayout.LayoutParams(ViewGroup.LayoutParams.MATCH_PARENT, ViewGroup.LayoutParams.WRAP_CONTENT); params.leftMargin = getResources().getDimensionPixelSize(R.dimen.dialog_margin); input.setLayoutParams(params); container.addView(input); alert.setTitle(“by…”); alert.setMessage(“test message”); alert.setView(container); Make sure you add another line to your dimens.xml resource file, such as <dimen name=”dialog_margin”>20dp</dimen>
Update 2022/10/22 Flutter 2.5 introduced the actionsAlignment property: AlertDialog( title: .. actions: .. actionsAlignment: MainAxisAlignment.end ), Customize widget Edit the the widget itself: Under the AlertDialog there is a ButtonBar widget where you can use alignment: MainAxisAlignment.spaceBetween to align the buttons correctly. See this answer for an example of a custom AlertDialog widget. Own button … Read more
The problem is that you are using private resource android.R.drawable.ic_dialog_alert. Using private resources is problematic, they can vary on different devices and you can’t even be sure that they are present on all devices. The best is to avoid using private resources. If you need them, you should copy them from Android sources and put … Read more
The first error line gives me the hint that this is related to how you are creating your dialog – not the dialog itself. Are you creating the dialog automatically (which could mean this gets called before the views are all set up) or in response to a button click? I initially had problems with … Read more
public MyAlertDialog( Context context, int theme ) extends AlertDialog { super(context, theme); getWindow().setBackgroundDrawable(new ColorDrawable(android.graphics.Color.TRANSPARENT)); }
Actually there is no any cancel() or dismiss() method from AlertDialog.Builder Class. So Instead of AlertDialog.Builder optionDialog use AlertDialog instance. Like, AlertDialog optionDialog = new AlertDialog.Builder(this).create(); Now, Just call optionDialog.dismiss(); background.setOnClickListener(new OnClickListener() { public void onClick(View v) { SetBackground(); // here I want to dismiss it after SetBackground() method optionDialog.dismiss(); } });
