Snackbar with API 21

Question

I'm trying to implement the new Snackbars in my app but I can't. First of all I downloaded the zip file from this SnackBarSampleActivity.
I unziped it and then I import it in Eclipse. Now I get an error retrieving parent... for the theme parent in styles.xml.
I change it to android:Theme.Light and the error was gone. I right clicked the project and checked isLibrary in Properties/Android, I right clicked my app and in Properties/Android I add the library. Finally I paste the code to show a Snackbar but I get an error because Snackbar cannot be resolved.
Please somebody help me! I'm going crazy, what am I doing wrong?

Answer 1

You should try to use Android Studio, because the ADT plugin for Eclipse is no longer in active development.

In Android Studio, you just need to add a line compile 'com.nispok:snackbar:2.6.1' in your build.gradle dependencies, such that

dependencies {
    compile fileTree(dir: 'libs', include: ['*.jar'])
    compile 'com.android.support:appcompat-v7:21.0.2'
    compile 'com.nispok:snackbar:2.6.1'
}

That's it.

For Eclipse Developers

1. Follow the instructions given in github to import SnackBar project
2. Right click on the java folder and click build path > add as source folder

3. add these lines/change SnackBar project's AndroidManifest.xml as follows

   <uses-sdk android:minSdkVersion="7"
       android:targetSdkVersion="22"/>
   <application />
   

package="com.nispok.snackbar"

4. Add following dependencies to the SnackBar project

android-support-v7-appcompat: 21
android-support-v7-recyclerview: 21

5. Finally set Project build target to API 22 in project properties.

That's it will be working for you, Have a great coding day..

With the new Design Support Library you can use the official SnackBar Widget.

Just add this dependency to your app -> build.gradle:

implementation 'com.android.support:design:28.0.0'

And use something like:

Snackbar.make(view, "Snackbar", Snackbar.LENGTH_LONG).show();

Full Example, In Kotlin

        val fab = findViewById(R.id.btn_signin) as Button
        fab.setOnClickListener(View.OnClickListener { view ->
            Snackbar.make(view, "FloatingActionButton is clicked", Snackbar.LENGTH_INDEFINITE)
                    .setAction("Action", null).show()
        })

If you are facing "not resolved to a type" issue in Eclipse for Snackbar, this worked for me.

Right click on Project->BuildPath->Configure Buildpath Click on Libraries Tab and then click on Add external Libraries.

Select {path of adt}/sdk/extras/android/support/design/libs Select android-support-design.jar, Click Open to add this library.

Click Ok.

Answer 5

Please add the below code to the build.gradle file

implementation 'com.android.support:design:28.0.0'

after that Click the Sync Now button,It will work.

Add this in your build.gradle (Module: app) inside dependencies:

implementation 'com.android.support:design:28.0.0'

or

implementation 'com.dmitrymalkovich.android:material-design-dimens:1.4'

Complete code:

dependencies {
    implementation 'com.android.support:design:28.0.0'
}

or

dependencies {
    implementation 'com.dmitrymalkovich.android:material-design-dimens:1.4'
}
