I am trying to add some animation in my Android app for a text change on a TextView.
I found a post with sample:
Smooth text change in android animation
Sample code:
TransitionManager.beginDelayedTransition(transitionsContainer,
new ChangeText().setChangeBehavior(ChangeText.CHANGE_BEHAVIOR_OUT_IN));
I have imported the following package:
import androidx.transition.TransitionManager;
However, when I use this, I get an error in Android Studio: Cannot resolve symbol ChangeText
What am I missing? Please help!
The original Answer mentions that a library is needed:
If you want to support Android 4+. check out the Transitions Everywhere lib. You can achieve all sorts of different animations with backward compatibility.
Here you can find some examples.
Therefore you might need to install the library via gradle and then import it like so:
import com.transitionseverywhere.ChangeText;
or
import com.transitionseverywhere.*;

I'm new in android programming , I downloaded project that uses holoeverywhere library so I wont to know if I can replace it by another one (like ActionBarSherlock replaced by AppCompat ) ? the project uses those , how I deal with it?
import org.holoeverywhere.app.Activity;
import org.holoeverywhere.widget.LinearLayout;
import org.holoeverywhere.widget.datetimepicker.date.DatePickerDialog;
I found this tutoria here but I its not working for me !
I can replace it with new library according to my code (my imports) ?
Please I need any solution !!
so i'm following a guide online to make a room db. In the adapter section i followed his way of doing it but when i did it, i keep having the "No Type Argument expected for Interface ListAdapter".
Error example: https://imgur.com/kPT7DkE
Here's the whole project so far on github.
https://github.com/OlivierLabelle/BudgetProject/tree/master/app/src/main/java/com/example/android/budgetproject
And the guide i was following.
https://medium.com/#trionkidnapper/recyclerview-more-animations-with-less-code-using-support-library-listadapter-62e65126acdb
So with the help of devboi, i found out i was using the wrong import.
In the top right corner on the Dev documentation it show the right import.

And here how the import on my project should look like.
import android.support.v7.recyclerview.extensions.ListAdapter
Just came across this very problem myself.
If you're using AndroidX/Jetpack/whatever the official name is I'm still new at this, Android Studio might
import android.widget.ListAdapter
automatically, but the one you want is
import androidx.recyclerview.widget.ListAdapter
From what I see in your code, you should replace ListAdapter<Transaction> with ListAdapter<Transaction, Viewholder>.
You can see an example in the docs here :(https://developer.android.com/reference/android/support/v7/recyclerview/extensions/ListAdapter.html), where ListAdapter has 2 arguments inside the diamonds: one for the list-object and the other for your custom viewholder.
Hope this helps.
According to the android developer page for the developer preview of L, it's possible to use the Outline class & define outlines for view's to display the shadows in the correct way.
(http://developer.android.com/preview/material/views-shadows.html#shadows)
In my case, the "L"-sdk I use, didn't found it. Therefore I couldn't import and use the class.
According to the test project, stored in sdk/samples/android-L/ui/views/Elevation/ElevationDrag this class should be stored in "android.graphics.outline", but even in this project it can't be located correctly.
Is this feature not implemented in the developer preview yet or did I missed something?
Finally got it.
It's a bug in android studio. I just added manually the import to my activity:
import android.graphics.Outline
It will be shown as error, but it can compile & run.
I hope they will fix this soon.
EDIT: I created an issue here: https://code.google.com/p/android/issues/detail?id=72788&q=android%20studio%20android%20l&colspec=ID%20Type%20Status%20Owner%20Summary%20Stars
It looks like, they're working on it.
The same problem than you but your answer it didn't work for me, I am trying to import
import android.graphics.outline;
And de output is:
Error:(7, 24) error: cannot find symbol class outline
The build.gradleseems to be well configurated with the
compileSdkVersion 'android-L'
sentence
** Fixed
the right import is: import android.graphics.Outline;
I'm newbie to android and must use image as Pinterest. i am using staggeredgridview using etsy demo but as soon as project is imported to eclipse it shows many errors is there any step to implement staggered demo?
Try Below code..
https://github.com/bulletnoid/StaggeredGridView
Hope Help you.
if the Existing Code is Correct, and It shows An error when you import the Project You need to Take Care of two things..
If you want to seed Demo... if a Existing Projects... it Depends on the Way You Import.
1.Some Existing Source codes can Be imported directly..
Like :
File>
Import >
Android >
Existing Android Code Into Work Space> Browse file..
But For Some Source Code In the Above Way you will Get Errors Definitely.. Due to incomplete Import..(I mean Eclipse may not import Complete Functionality)
If you Get Errors in First Way choose Second Way..
2.Second Way to Import
File>
other>
Android >
Android project from Existing Code> Browse file..
I hope this is Problem..
Or Else Please Mention Your Log Cat Code so that the Error will be Fixed..
Update
One More thing If you are Using Android Build Tools.. It may a problem for some old codes..
So you need to Use Separate Eclipse J2EE kepler IDE and Android SDK ...
See here for Reference...
One Place Your Log Cat.. I will Solve Problem...
You can go with this link:
It explains few steps as follows:
Just Use a Grid List
Try a Modified GridView with Staggered Grid View
Try a Modified List with Pinterest Like Adapter View
Or Try Two Synced List Views with Pinterest List View
You might not have change your Package Name or i would be good if you have posted error.
The method getWsUrl() is undefined for the type Configuration
for this line
AndroidHttpTransport _ht = new
AndroidHttpTransport(Configuration.getWsUrl());
how can ı solve it?
You probably imported the wrong Configuration. Right now, your import likely points to android.content.res.Configuration.
However, your code snippet suggests you're using (parts of) some Google Code project, androidzon. It has a webservice package that includes a Configuration class with the method you're looking for. It appears to mean something like 'get webservice url'. You will want to correct your import and/or add the missing classes/libraries to your Android project.
Do note that you appear to be using old code, as the latest revision of that Configuration class does not include the getWsUrl() anymore. In stead, there is a getServerAddress() method.
