Recyclerview not scrolling to end when keyboard opens
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.
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);
}
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);
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);
}
});
}
});
}
