Transition Manager - Sliding A View Out Is Not Working As Wanted

I'm trying to slide this view in and out using Transition + Transition manager, however when hitting the hide button to make the view GONE it doesn't have the sliding animation. H

Solution 1:

Not sure whats wrong with your code. i have created a sample, just try the code below it working fine. make sure to add android:visibility="gone" for panel view in layout so that its hidden at first launch.

publicclassMainActivityextendsAppCompatActivity {
booleanisShowing=false;

@OverrideprotectedvoidonCreate(Bundle savedInstanceState) {
    super.onCreate(savedInstanceState);
    setContentView(R.layout.activity_damm_activty);
    findViewById(R.id.testBtn).setOnClickListener(v -> {
        showSlidingPanel(!isShowing);
    });
}

privatevoidshowSlidingPanel(boolean show) {
    ViewGroupparent= findViewById(R.id.main_activity_root_view);
    Viewlayout= findViewById(R.id.layout);
    Transitiontransition=newSlide(Gravity.START);
    transition.setDuration(450);
    transition.addTarget(R.id.layout);
    transition.setInterpolator(newAccelerateDecelerateInterpolator());
    TransitionManager.beginDelayedTransition(parent, transition);
    layout.setVisibility(show ? View.VISIBLE : View.GONE);
    isShowing = show;
}
}

Solution 2:

Create these animations

slide up

<translateandroid:duration="400"android:fromYDelta="100%"android:toYDelta="0" />

slide down

<translateandroid:duration="400"android:fromYDelta="0"android:toYDelta="100%" />

When you want to set the layout visible

binding.musicOptionsLayout.setVisibility(View.GONE); binding.musicOptionsLayout.startAnimation(AnimationUtils.loadAnimation(getApplicationContext(), R.anim.slide_down));

When you want to set the layout Gone

binding.musicOptionsLayout.setVisibility(View.GONE); binding.musicOptionsLayout.startAnimation(AnimationUtils.loadAnimation(v.getContext(), R.anim.slide_down));

set android:visibility="gone" on XML..

Hope this will fix your issues...
