I have a ListView which displays search results. When a search is being performed, I add a footer to the ListView which indicates that a search is in progress. I'd like to programmatically scroll my ListView to the bottom so the footer is visible to the user. Ideas?
My app is targeted to 2.1+
Use this method to scroll the ListView to bottom.
private void scrollMyListViewToBottom() {
myListView.post(new Runnable() {
#Override
public void run() {
// Select the last row so it will scroll into view...
myListView.setSelection(myListAdapter.getCount() - 1);
}
});
}
Taken from Listview Scroll to the end of the list after updating the list
try with this
lv.post(new Runnable() {
#Override
public void run() {
lv.setTranscriptMode(ListView.TRANSCRIPT_MODE_ALWAYS_SCROLL);
lv.setStackFromBottom(true);
}
});

How to force a click or touch an item on a recyclerview?
I found people talking to use a command recyclerView.findViewHolderForAdapterPosition(0).itemView.performClick() but recyclerView.findViewHolderForAdapterPosition(0) always returns null!
I want initially that the first recyclerview item is clicked/ touched.
new Handler().postDelayed(new Runnable() {
#Override
public void run() {
recyclerView.findViewHolderForAdapterPosition(position).itemView.performClick();
}
},100);
I dont want to scroll it (becz i think it takes time and perfomance to scroll). I want to set it already scrolled to bottom at the start of the activity like whatsapp.
How could this be done?
If you want your ListView to be always scrolled at the bottom even on updating, you can add these attributes to the list:
android:stackFromBottom="true"
android:transcriptMode="alwaysScroll"
Otherwise use :
listView.setSelection(adapter.getCount() - 1);
listview.setSelection(LastItemIndexInListView);
LastItemIndexInListView : size of listview - 1.
listView.post(new Runnable() {
#Override
public void run() {
listView.scrollTo(0, listView.getBottom());
}
});
Give this a shot.
listView.post(new Runnable() {
#Override
public void run() {
listView.setSelection(listView.getCount() - 1);
}
});
This should work for you
I have a ListView in my RelativeLayout that is supposed to be hidden during a search is executed. Therefore I implemented the following code:
mProgressView.setVisibility(View.VISIBLE);
mSearchListView.setVisibility(View.INVISIBLE);
mSearchAdapter.search(query).onSuccess(new Continuation<Set<Integer>, Object>() {
#Override
public Object then(final Task<Set<Integer>> task) throws Exception {
runOnUiThread(new Runnable() {
#Override
public void run()
mSearchAdapter.notifyDataSetChanged();
mProgressView.setVisibility(View.INVISIBLE);
mSearchListView.setVisibility(View.VISIBLE);
}
});
return null;
}
});
Unfortunately, the ListView stays visible. The ProgressView start to spin successfully but the list view remains visible. Any hints on what to do?
When you say it stays 'visible' do you mean you see data in the listview or just that some space seems to be occupied by an invisible listview?
If the latter is the case then you should try making the listview GONE as -
mSearchListView.setVisibility(View.GONE);
instead of making it invisible
I have a listview where pople can click on items. When they do, they increase height and show more information.
However, when clicking the bottom item, it is not visible to the user that the item height has increased and there is content if you scroll down.
Using e.g. following code in onItemClick does not solve the problem:
if (position == myItemsDataArrayList.size() - 1) {
if (data.ui_flags == "clicked") {
catalogListView.smoothScrollToPosition(position);
}
}
Implement this function in your if statement.
private void scrollMyListViewToBottom() {
myListView.post(new Runnable() {
#Override
public void run() {
// Select the last row so it will scroll into view...
myListView.setSelection(myListAdapter.getCount() - 1);
}
});
}

Working code solution was this:
catalogListView.post(new Runnable() {
#Override
public void run() {
catalogListView.setSelection(position_final);
}
});
I have a Listview in Android. I want that the Listview continuously scrolls from top to bottom by itself. It should happen infinitely
And obviously I want to capture the click on any of the items of the Listview, post that the scroll will continue
Anybody having experience with such an implementation. Please help !!

To scroll automatically, you can use this: listView.smoothScrollToPosition(position);
private void scrollMyListViewToBottom() {
myListView.post(new Runnable() {
#Override
public void run() {
// Select the last row so it will scroll into view...
listView.smoothScrollToPosition(myListAdapter.getCount() - 1);
// Just add something to scroll to the top ;-)
}
});
}
