• in your android studio project you must add this in your build.gradle(app) depedencies

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

• and implement dataBinding in your build.gradle(app) android

android {
  ...
  dataBinding {
      enabled true
  }
  ...
}

Installing

• Clone or download this repo
• Copy folder TabActivityTemplate to

for windows user:

{ANDROID_STUDIO_LOCATION}/plugins/android/lib/templates/activities/

for mac user:

/Applications/Android Studio.app/Contents/plugins/android/lib/templates/activities/

• open Android Studio (if you already opened android studio, restart it)
• right click on a package that you want to create the template in and select it from the New menu, as below:

• You will then be prompted to fill in the variables see the example below:

• You will see some error code, that's because you must import some code before you can continue.
• if you found error Unresolved reference SingleLiveEvent then you must create a class named SingleLiveEvent.kt here is the code

class SingleLiveEvent<T> : MutableLiveData<T>() {

    private val pending = AtomicBoolean(false)

    @MainThread
    override fun observe(owner: LifecycleOwner, observer: Observer<T>) {

        if (hasActiveObservers()) {
            Log.w(TAG, "Multiple observers registered but only one will be notified of changes.")
        }

        // Observe the internal MutableLiveData
        super.observe(owner, Observer<T> { t ->
            if (pending.compareAndSet(true, false)) {
                observer.onChanged(t)
            }
        })
    }

    @MainThread
    override fun setValue(t: T?) {
        pending.set(true)
        super.setValue(t)
    }

    /**
     * Used for cases where T is Void, to make calls cleaner.
     */
    @MainThread
    fun call() {
        value = null
    }

    companion object {
        private const val TAG = "SingleLiveEvent"
    }
}

• if the error has gone, you must add this in your androidManifest.xml

if this is your first activity, than use this code

<manifest ...>
    <application ...>
        
        <activity android:name="{name of your activity}">
            <intent-filter>
                <action android:name="android.intent.action.MAIN" />

                <category android:name="android.intent.category.LAUNCHER" />
            </intent-filter>
        </activity>
        
    </application>
</manifest>

but if there is another activity existed use this code

<manifest ...>
    <application ...>
        
        <activity android:name="{name of your activity}"></activity>
        
    </application>
</manifest>
