snackbar

I am trying to use a Snackbar . I have a FloatingActionButton wrapped in a CoordinatorLayout . When the Snackbar shows, the button is correctly moved up. When it dismisses automatically, the button moves down. But if I dismiss the Snackbar programmatically, the button does not go down. My code is simple: mSnackbar = Snackbar.make(mCoordinatorLayout, text, Snackbar.LENGTH_LONG) .setAction(R.string.undo, new View.OnClickListener() { @Override public void onClick(View v) { undoDeleteTasks(); } }); mSnackbar.show(); Is there a way to make the FloatingActionButton move down when the Snackbar is

From Documentation: parameter duration - either be one of the predefined lengths: LENGTH_SHORT, LENGTH_LONG, or a custom duration in milliseconds . But I can't set custom duration. For example Snackbar .make(parentLayout, "Feed cat?", 8000) // try here .setAction("Yes", snackOnClickListener) .setActionTextColor(Color.MAGENTA) .setDuration(8000) // try here .show(); but instead of 8 seconds Snackbar gone quickly. CommonsWare Based on the implementation of Snackbar and SnackbarManager , I can confirm Eugene H's assessment: it's a bug. From SnackbarManager : private void scheduleTimeoutLocked

I wanted to try out the new Snackbar from the official design library provided by Google. Its usage is very close to a Toast so I thought it would be simple enough to try out. I've tried it out on an emulator running 5.1 as well as Samsung Galaxy S6 Edge running 5.0. My problem is that the app crashes when it's supposed to display the Snackbar. Code package com.jayway.andreas.test; import android.app.Activity; import android.os.Bundle; import android.support.design.widget.Snackbar; import android.view.View; public class MainActivity extends Activity { @Override protected void onCreate(Bundle

I want to display a simple SnackBar inside Flutter 's stateful widget. My application creates new instance of MaterialApp with a stateful widget called MyHomePage . I try to show the SnackBar in showSnackBar() method. But it fails with ' The method 'showSnackBar' was called on null '. What's wrong with this code? class MyApp extends StatelessWidget { @override Widget build(BuildContext context) { return new MaterialApp( title: 'Flutter', theme: new ThemeData( primarySwatch: Colors.blue, ), home: new MyHomePage(), ); } } class MyHomePage extends StatefulWidget { MyHomePage({Key key}) : super

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(BuildContext context) { return Scaffold( appBar: AppBar( title: Text('SnackBar Playground'), ), body: Center(

Is there a way to prevent the user from dismissing a snackbar by swiping on it? I have an app that shows a snack bar during network login, I want to avoid it to be dismissed. According to Nikola Despotoski suggestion I've experimented both solutions: private void startSnack(){ loadingSnack = Snackbar.make(findViewById(R.id.email_login_form), getString(R.string.logging_in), Snackbar.LENGTH_INDEFINITE) .setAction("CANCEL", new OnClickListener() { @Override public void onClick(View view) { getOps().cancelLogin(); enableControls(); } }); loadingSnack.getView().setOnTouchListener(new View

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 using. I tried setOnSystemUiVisibilityChangeListener() but that didn't work, I believe it is only for
