Collapsingtoolbarlayout Not Collapsing When Edittext Get Focused

I am using CollapsingToolBar inside CoordinatorLayout and I've NestScrollView containing some EditText as child views. What i am facing is when edittext get focused and keybaoard a

Solution 1:

I've resolved this by adding OnFocusChangeListener to EditText and if it has focus - just collapse view with setExpanded method:

editText.setOnFocusChangeListener(newView.OnFocusChangeListener() {
    @OverridepublicvoidonFocusChange(final View v, boolean hasFocus) {
        if (hasFocus) {
           mAppBarLayout.setExpanded(false, true);
        }
    }
});

If you want your CollapsingToolbarLayout be collapsed every time when your other EditText's from your layout get focused, then you should set the same OnFocusChangeListener to each of them.

Solution 2:

RecyclerView is a scrollable widget which means, these scrollable widgets won't work with eachother.(But, RecyclerView is a child from NestedScrollingChild)

Check this question for more explanation:

But, you can use it with customLinearLayoutManager

By the way,

You could use that RecyclerView inside the CoordinatorLayout and outside the NestedScrollView.

Hope that helps.

Solution 3:

I think after all researches this is the best solution

editText.setOnFocusChangeListener(newView.OnFocusChangeListener() {
@OverridepublicvoidonFocusChange(final View v, boolean hasFocus) {
    if (hasFocus) {
        mAppBarLayout.setExpanded(false, true); // second one for animation
    }
}
});
