问题 Is there a way to make the snackbar push the view upwards when it is shown? Currently, when the snackbar is shown, it overlays the view below so it looks like half the button is cut off but I want it to almost "adjustPan" similar to the way that the softkeyboard works when it is shown on the screen. Does anyone know of any tricks to achieve this? 回答1: Put your view inside a android.support.design.CoordinatorLayout <android.support.design.widget.CoordinatorLayout android:id="@+id/coordinator"

问题 I have a TextView at the bottom of the CoordinatorLayout . But when I show a SnackBar , it will cover the TextView . I know I have to customize a Behavior for the TextView and override layoutDependsOn and onDependentViewChanged ,but it doesn't fix very well. Could you give me some advice if you know?

问题 I'm using a Snackbar from the com.android.support:design:22.2.0 library. I'm using it to undo deletions. To make my life easier, I'm going to make the UI look like things are actually deleted from the data source, and if the undo button in the snack bar is not pressed, actually perform the deletions from the data source. So, I want to know when the Snackbar is no longer visible, so it's safe to delete the items. I can call getView() on the Snackbar, but I'm not sure what listener I should be

问题 I see that the Snackbar will only take either LENGTH_LONG or LENGTH_SHORT when determining the length of its display on screen. I would like to have it displayed until someone swipes it off the screen. This is for some cases when you have persistent errors, like when you have no internet and you want to notify the user without having it disappearing off the screen after 2750ms when selecting LENGTH_LONG. Of course I can use setDuration to a ridiculously long milliseconds values, but is there

问题 Snackbars provide lightweight feedback about an operation by showing a brief message at the bottom of the screen. Snackbars can contain an action. Android also provides a toast, primarily used for system messaging. Toasts are similar to snackbars but do not contain actions and cannot be swiped off screen. My question import android.content.BroadcastReceiver; import android.content.Context; import android.content.Intent; import android.widget.Toast; public class TestReceiver extends

问题 How does Google Inbox show the snackbar over (covering, layering) the keyboard? This is not the default behaviour, which I've tested with a basic coordinator layout, the keyboard open and a snackbar: the default behaviour is showing the snackbar behind the keyboard. There are many answers on SO to the question: 'How do I show the snackbar above the keyboard' , but I haven't found how to reproduce Google's own Inbox app's snackbar behaviour. Can you show me how to achieve this? 回答1: Inbox

问题 We could set the color for the Action Text of Snackbar using setActionTextColor as documented in https://developer.android.com/reference/android/support/design/widget/Snackbar.html. However, is there a way to make the Text BOLD? Thanks!! 回答1: Use snackbar_action Resource ID. It turns you that you can use the same method to style the Snackbar's Action text that you use to style the Snackbar's Message text. You just have to use the Resource ID snackbar_action instead of snackbar_text . Here's

问题 As you can see my button is inside Scaffold's body. But I get this exception: Scaffold.of() called with a context that does not contain a Scaffold. import 'package:flutter/material.dart'; void main() => runApp(MyApp()); class MyApp extends StatelessWidget { @override Widget build(BuildContext context) { return MaterialApp( title: 'Flutter Demo', theme: ThemeData( primarySwatch: Colors.blue, ), home: HomePage(), ); } } class HomePage extends StatelessWidget { @override Widget build
