FrameLayout and AbsListView convert their children layout params to FrameLayout.LayoutParams and AbsListView.LayoutParams. This is where the casting fails. View header = View.inflate(this, R.layout.header_layout, null); should fix it. Edit: As mentioned in the comments, changing the ViewGroup Parameter of the inflate call also makes it work: header = inflater.inflate(R.layout.header_layout, null, false);
The answer is very simple: you should change android:layout_height=”wrap_content” to android:layout_height=”match_parent” in your ListView. You can probably guess why this happens.
The OnItemSelectedListener listens for list item selections and not list item clicks. A selection in this case could be seen as moving the focus on this item with the device’s trackpad. To get the wanted behavior one must use the OnItemClickListener.
You will want to remove() the item from your adapter object and then just run the notifyDatasetChanged() on the Adapter, any ListViews will (should) recycle and update on it’s own. Here’s a brief activity example with AlertDialogs: adapter = new MyListAdapter(this); lv = (ListView) findViewById(android.R.id.list); lv.setAdapter(adapter); lv.setOnItemClickListener(new OnItemClickListener() { public void onItemClick(AdapterView<?> a, View v, … Read more
I’ve figured it out. I couldn’t understand how the hell the adapter started and how did it know where to get the data from. When i extended the BaseAdapter class, in the constructor of that class I initialized the list of items that I wanted to see in the ListView. But I couldn’t figure out … Read more
This implementation works quite good. There is some flickering though, probably because of altered indices when the adapter add new views to top or bottom..That could be possibly solved by watching for changes in the tree and shifting the indices on the fly.. public class ElasticListView extends GridView implements AbsListView.OnScrollListener, View.OnTouchListener { private static int … Read more
You should use the more verbose android:background=”@android:color/transparent” android:cacheColorHint=”@android:color/transparent” Updated with Jacky’s response. I originally merely meant to add to his answer, since he was using a plain hex color in the sample.
A classic hack for situations like this is to use a handler and postDelayed(). In your adapter: private int lastFocussedPosition = -1; private Handler handler = new Handler(); public View getView(final int position, View convertView, ViewGroup parent) { // … edittext.setOnFocusChangeListener(new OnFocusChangeListener() { @Override public void onFocusChange(View v, boolean hasFocus) { if (hasFocus) { handler.postDelayed(new … Read more
HERE IS SIMPLER AND CLEANER APPROACH. Implement Endless Scrolling from this Codepath Guide and then follow the following steps. 1. Add progress bar under the RecyclerView. <android.support.v7.widget.RecyclerView android:id=”@+id/rv_movie_grid” android:layout_width=”0dp” android:layout_height=”0dp” android:paddingBottom=”50dp” android:clipToPadding=”false” android:background=”@android:color/black” app:layout_constraintBottom_toBottomOf=”parent” app:layout_constraintEnd_toEndOf=”parent” app:layout_constraintStart_toStartOf=”parent” app:layout_constraintTop_toTopOf=”parent”> </android.support.v7.widget.RecyclerView> <ProgressBar android:id=”@+id/progressBar” style=”?android:attr/progressBarStyle” android:layout_width=”wrap_content” android:layout_height=”wrap_content” android:visibility=”invisible” android:background=”@android:color/transparent” app:layout_constraintBottom_toBottomOf=”parent” app:layout_constraintEnd_toEndOf=”parent” app:layout_constraintStart_toStartOf=”parent” /> Here android:paddingBottom=”50dp” and android:clipToPadding=”false” are very … Read more
Changed means the data set changed. Individual items updated, or items were added or removed. Invalidated means the data source is no longer available.
