Recyclerview not scrolling to end when keyboard opens
AndroidListviewAndroid RecyclerviewAndroid SoftkeyboardAndroid Problem Overview
I am using recylerview in my application and whenever new element is added to recyclerview, it scrolls to last element by using
recyclerView.scrollToPosition(adapter.getCount());
But, whenever keyboard opens(because of editTextView), it resizes the view and recyclerview gets smaller, but couldn't scroll to last element.
android:windowSoftInputMode="adjustResize"
I even tried to used the following code to scroll to last element, but it didn't work
editTextView.setOnFocusChangeListener(new View.OnFocusChangeListener() {
@Override
public void onFocusChange(View v, boolean hasFocus) {
if(hasFocus){
recyclerView.scrollToPosition(chatAdapter.getItemCount());
}
}
});
I can try adjustPan to shift the pan up, but it is hiding my toolbar.
Please suggest any way to rectify the issue.

Solution 1 - Android
You can catch keyboard up changes using recyclerview.addOnLayoutChangeListener().
If bottom is smaller than oldBottom then keyboard is in up state.
if ( bottom < oldBottom) {
recyclerview.postDelayed(new Runnable() {
@Override
public void run() {
recyclerview.smoothScrollToPosition(bottomPosition);
}
}, 100);
}
Solution 2 - Android
Add this your activity or fragment:
if (Build.VERSION.SDK_INT >= 11) {
recyclerView.addOnLayoutChangeListener(new View.OnLayoutChangeListener() {
@Override
public void onLayoutChange(View v,
int left, int top, int right, int bottom,
int oldLeft, int oldTop, int oldRight, int oldBottom) {
if (bottom < oldBottom) {
recyclerView.postDelayed(new Runnable() {
@Override
public void run() {
recyclerView.smoothScrollToPosition(
recyclerView.getAdapter().getItemCount() - 1);
}
}, 100);
}
}
});
}

It works for me
LinearLayoutManager layoutManager = new LinearLayoutManager(context);
layoutManager.setStackFromEnd(true);
recyclerView.setLayoutManager(layoutManager);
Solution 4 - Android
I found the postDelayed to be unnecessary and using adapter positions doesn't account for when the recycler is scrolled to somewhere in the middle of an item. I achieved the look I wanted with this:
recycler.addOnLayoutChangeListener((view, left, top, right, bottom, oldLeft, oldTop, oldRight, oldBottom) -> {
if (bottom < oldBottom) {
messageRecycler.scrollBy(0, oldBottom - bottom);
}
})

Although this an old question, I experienced this problem today and I found out that none of of the above method works. This is my solution
recyclerView.addOnLayoutChangeListener(new View.OnLayoutChangeListener() {
@Override
public void onLayoutChange(View v,
int left, int top, int right, int bottom,
int oldLeft, int oldTop, int oldRight, int oldBottom) {
if (bottom < oldBottom) {
final int lastAdapterItem = mAdapter.getItemCount() - 1;
recyclerView.post(new Runnable() {
@Override
public void run() {
int recyclerViewPositionOffset = -1000000;
View bottomView = linearLayoutManager.findViewByPosition(lastAdapterItem);
if (bottomView != null) {
recyclerViewPositionOffset = 0 - bottomView.getHeight();
}
linearLayoutManager.scrollToPositionWithOffset(lastAdapterItem, recyclerViewPositionOffset);
}
});
}
});
}

This works.
private RecyclerView mRecyclerView;
private RecyclerView.Adapter mAdapter;
private LinearLayoutManager mManager;
...
mManager = new LinearLayoutManager(this);
mRecyclerView.setLayoutManager(mManager);
(initialize and set adapter.)
mRecyclerView.addOnLayoutChangeListener(new View.OnLayoutChangeListener() {
@Override
public void onLayoutChange(View v, int left, int top, int right, int bottom, int oldLeft, int oldTop, int oldRight, int oldBottom) {
if (bottom < oldBottom) scrollToBottom();
}
});
private void scrollToBottom() {
mManager.smoothScrollToPosition(mRecyclerView, null, mAdapter.getItemCount());
}
Solution 7 - Android
recyclerView.smoothScrollToPosition(recyclerView.getAdapter().getItemCount());
Solution 8 - Android
It works properly in support library version 27.0.1
There is nothing to set in the manifest.
val currentScrollPosition = 0
recyclerView.addOnScrollListener(object : RecyclerView.OnScrollListener() {
override fun onScrolled(recyclerView: RecyclerView?, dx: Int, dy: Int) {
super.onScrolled(recyclerView, dx, dy)
currentScrollPosition = recyclerView.computeVerticalScrollOffset() + recyclerView.computeVerticalScrollExtent()
}
override fun onScrollStateChanged(recyclerView: RecyclerView?, newState: Int) { }
})
storyList.addOnLayoutChangeListener { view, left, top, right, bottom, oldLeft, oldTop, oldRight, oldBottom ->
if (bottom < oldBottom) {
if (currentScrollPosition >= recyclerView.computeVerticalScrollRange()) {
recyclerVIew.post {
recyclerView.overScrollMode = RecyclerView.OVER_SCROLL_NEVER
recyclerView.smoothScrollBy(0, recyclerView.computeVerticalScrollRange() - recyclerView.computeVerticalScrollOffset() + recyclerView.computeVerticalScrollExtent())
}
}
} else {
recyclerView.overScrollMode = RecyclerView.OVER_SCROLL_ALWAYS
}
}
Solution 9 - Android
layoutManager.scrollToPositionWithOffset(chatMessageAdapter.getItemCount() - 1, 0);

You can use addOnItemTouchListener to see the scrolling change:
private Boolean scrollListerActivate = true;
mRecyclerViewTop.addOnScrollListener(new RecyclerView.OnScrollListener() {
@Override
public void onScrolled(RecyclerView recyclerView, int dx, int dy) {
super.onScrolled(recyclerView, dx, dy);
if(scrollListerActivate == true) {
scrollListTopManager();
}
}
});
To scroll for last (or other) position you should use scrollListTopManager method:
public void scrollListTopManager() {
int position = 0;
int itemCount = mRecyclerViewTop.getAdapter().getItemCount();
position = itemCount - 1;
mRecyclerViewTop.scrollToPosition(position);
}
You should also use addOnItemTouchListener to stop using scrollListTopManager method, if you want to scroll manually:
mRecyclerViewTop.addOnItemTouchListener(new RecyclerView.OnItemTouchListener() {
@Override
public boolean onInterceptTouchEvent(RecyclerView recyclerView, MotionEvent
motionEvent) {
scrollListerActivate = false;
return false;
}
@Override
public void onTouchEvent(RecyclerView recyclerView, MotionEvent motionEvent)
{}
@Override
public void onRequestDisallowInterceptTouchEvent(boolean b) {}
});

Bind the RecyclerView inside NestedScrollView
<android.support.v4.widget.NestedScrollView
android:layout_width="match_parent"
android:layout_height="match_parent">
<android.support.v7.widget.RecyclerView
android:id="@+id/recycler_view"
android:layout_width="match_parent"
android:layout_height="wrap_content"/>
</android.support.v4.widget.NestedScrollView>
