Android DataBinding Activity finish()
.everyoneloves__top-leaderboard:empty,.everyoneloves__mid-leaderboard:empty,.everyoneloves__bot-mid-leaderboard:empty{ height:90px;width:728px;box-sizing:border-box;
}
I am trying to implement MVVM in my app with DataBinding library. For simple tasks that I have accomplish I can find the way out, but problem is that I cannot finish activity after some action.
Problem:
After receiving specific broadcast I have to close activity from ViewModel class. Since VM class doesn't have reference of the View, how can I finish the activity?
To be precise, I have splash screen and corresponding VM class for it that starts IntentService for downloading a data. After the data has been downloaded I have to finish the splash screen and start MainActivity. I have found the way to start new Activity from VM, but to finish the previous one is the mystery.
Can you please help me?
Thanks!

Create a SplashStatus model with a ObservableBoolean:
private static class SplashStatus {
public final ObservableBoolean isFinished = new ObservableBooelan();
}
Here is your Splash layout:
<layout xmlns:android="http://schemas.android.com/apk/res/android">
<data>
<variable name="status" type="com.example.SplashStatus"/>
</data>
<LinearLayout
android:orientation="vertical"
android:layout_width="match_parent"
android:layout_height="match_parent">
<TextView android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:text="Splash Screen"
android:onFinish="@{status.isFinished}"/>
</LinearLayout>
</layout>
And binding adapter method:
@BindingAdapter("android:onFinish")
public static void finishSplash(View view, boolean isFinished) {
if(isFinished){
((Activity)(view.getContext())).startActivity(new Intent(view.getContext(), MainActivity.class))
((Activity)(view.getContext())).finish();
}
}
In the SplashActivity.java init your data binding on onCreate. Whenever you assign isFinished.set(true) onFinished method will start your MainActivity and finish current.

if you want just to finish() the activity from layout with databinding:
android:onClick="@{(view)->((Activity)(view.getContext())).finish()}"

Create a SplashStatus model with a ObservableBoolean:
private static class SplashStatus {
public final ObservableBoolean isFinished = new ObservableBooelan();
}
Here is your Splash layout:
<layout xmlns:android="http://schemas.android.com/apk/res/android">
<data>
<variable name="status" type="com.example.SplashStatus"/>
</data>
<LinearLayout
android:orientation="vertical"
android:layout_width="match_parent"
android:layout_height="match_parent">
<TextView android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:text="Splash Screen"
android:onFinish="@{status.isFinished}"/>
</LinearLayout>
</layout>
And binding adapter method:
@BindingAdapter("android:onFinish")
public static void finishSplash(View view, boolean isFinished) {
if(isFinished){
((Activity)(view.getContext())).startActivity(new Intent(view.getContext(), MainActivity.class))
((Activity)(view.getContext())).finish();
}
}
In the SplashActivity.java init your data binding on onCreate. Whenever you assign isFinished.set(true) onFinished method will start your MainActivity and finish current.
