Fix blinking effect when scrolling down Recyclerview with custom behaviour - java

I have a code that is experiencing a weird behaviour when scrolling the view down the second time. Basically, the app bar layout should resize the vertical space when swiping down and the user should be able to see the entire image. But when swiping down the second time the screen starts blinking super fast. Any help it'll be greatly appreciated.

By the way, the activity containing these fragments has a viewpager. I don't know if that would be relevant. But just to let you guys know.

how to callback from fragment to activity With bottom sheet

Hey I'm doing filtering data on my project using bottom Sheet with view-pager and two fragments i can pass data from activity to view-pager adapter and get in fragment through constructor but how can i get data from fragment to activity using bottom-sheet
this is how i send data from activity
adapter = new PagerAdapters(this.getSupportFragmentManager(),
tabLayout.getTabCount(),_id);
and receive data with constructor in fragment
public Filterfragment(String _id) {
this._id = _id;
}
And I'm using recyclerview to show data like this
So how can i send id of the item to activity so i can reload my recyclerview data when the apply button click.

Android Altbeacon .Print all found beacons informations using custom adapter and Listview

FrameLayout does not match_parent

I am using fragNav and bottombar plugin. I am trying to make a fullscreen fragment through a FrameLayout. By default, those plugins came with an actionBar which i delete in my theme with "Theme.AppCompat.Light.NoActionBar". But Once i did this there is still a white bar on top on my screen. When i look at hierarchyView it appears that my FrameLayout is not matching the parent but all my xml are setup with match_parent width and height..

In your parent RelativeLayout in fragment_first can you remove the android:fitsSystemWindows="true", I think that may be the cause of the issue.

I have multiple recyclerViews ,which should appear after another XML view,

I have multiple recyclerViews ,which should appear after another XML view, but they just don't , am using an adapter class to manage this. after using log.v I found that the the functions itself"in Adappter class" arent called , and i don't know why ??

List View not calling onItemClickListener and OnItemLongClickListener

I have implemented an abstract class that has a List View like so:
public abstract class ExampleListFragment extends ExampleFragment{
protected ListView _listView;
public ExampleListFragment () {
super();
}
public View onCreateView(LayoutInflater inflater, ViewGroup container, Bundle savedInstanceState) {
//Set Up the Bottom Bar
View view = super.onCreateView(inflater, container, savedInstanceState);
addList();
return view;
}
#Override
public void onAttach(Activity activity) {
super.onAttach(activity);
}
public void addList() {
_listView = new ListView(getActivity());
RelativeLayout.LayoutParams parms = new RelativeLayout.LayoutParams(RelativeLayout.LayoutParams.WRAP_CONTENT, RelativeLayout.LayoutParams.WRAP_CONTENT);
parms.addRule(RelativeLayout.CENTER_HORIZONTAL);
parms.addRule(RelativeLayout.BELOW, R.id.tableLayout);
_listView.setLayoutParams(parms);
_listView.setClickable(true);
_listView.setFocusable(true);
_listView.setOnItemLongClickListener(new AdapterView.OnItemLongClickListener() {
#Override
public boolean onItemLongClick(AdapterView<?> adapterView, View view, int i, long l) {
longListClick(i);
return true;
}
});
_listView.setOnItemClickListener(new AdapterView.OnItemClickListener() {
#Override
public void onItemClick(AdapterView<?> adapterView, View view, int i, long l) {
listClick(i);
}
});
_layout.addView(_listView);
}
public abstract void longListClick(int pos);
public abstract void listClick(int pos);
}
I then have a class that inherits from this to implement the abstract methods which should be called when clicking an item in the list
public class TwitterFragment extends ExampleListFragment {
private TwitterAdapter _adapter;
//...
#Override
public void onSelected() {
_adapter = new TwitterAdapter(getActivity());
populateAdapter();
}
private void populateAdapter() {
showLoadingTweets();
new TwitterGetTimelineTask().execute(username); //fills adapter with Twitter status info...
}
#Override
public void longListClick(int pos) {
Toast toast = Toast.makeText(getActivity(),String.format("You have clicked item number: %d",pos),
Toast.LENGTH_SHORT);
toast.show();
}
#Override
public void listClick(int pos) {
Toast toast = Toast.makeText(getActivity(),String.format("You have clicked item number: %d",pos),
Toast.LENGTH_SHORT);
toast.show();
}
//...
class TwitterGetTimelineTask extends AsyncTask<String, String, String> {
//...
}
}
However, whenever I click on an Item, it does not appear to even enter onItemClick functions.
Any ideas? help much appreciated.
*EDIT*
As requested, here is the code for my Adapter
public class TwitterAdapter extends BaseAdapter {
private ArrayList<StatusDetails> _statusDetailsArrayList;
private LayoutInflater _inflater;
public TwitterAdapter(Context context) {
_statusDetailsArrayList = new ArrayList<StatusDetails>();
_inflater = LayoutInflater.from(context);
}
#Override
public int getCount() {
return _statusDetailsArrayList.size();
}
#Override
public Object getItem(int i) {
return _statusDetailsArrayList.get(i);
}
#Override
public long getItemId(int i) {
return _statusDetailsArrayList.get(i).get_id();
}
#Override
public View getView(int i, View view, ViewGroup viewGroup) {
ViewHolder holder;
if (view == null) {
view = _inflater.inflate(R.layout.twitter_layout, null);
holder = new ViewHolder();
holder.img_icon = (ImageView) view.findViewById(R.id.statusImage);
holder.text_line1 = (TextView) view.findViewById(R.id.statusText);
holder.text_line2 = (TextView) view.findViewById(R.id.statusDateText);
view.setTag(holder);
} else {
holder = (ViewHolder) view.getTag();
}
Bitmap bmp = _statusDetailsArrayList.get(i).get_profile();
if (bmp == null) {
holder.img_icon.setImageResource(R.drawable.ic_action_twitter);
} else {
holder.img_icon.setImageBitmap(bmp);
}
holder.text_line1.setText(_statusDetailsArrayList.get(i).get_text());
holder.text_line2.setText(_statusDetailsArrayList.get(i).get_date());
return view;
}
public void addStatus(StatusDetails details) {
_statusDetailsArrayList.add(details);
}
public void setStatuses(ArrayList<StatusDetails> details) {
_statusDetailsArrayList = details;
}
public ArrayList<StatusDetails> getEvents() {
return _statusDetailsArrayList;
}
public void removeAll() {
_statusDetailsArrayList.clear();
}
private class ViewHolder {
ImageView img_icon;
TextView text_line1;
TextView text_line2;
}
}
And if needed, the XML of the layout of each list
<ImageButton
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:id="#+id/statusImage"
android:layout_alignParentTop="true"
android:layout_alignParentLeft="true" />
<TextView
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:textAppearance="?android:attr/textAppearanceSmall"
android:text="Status"
android:id="#+id/statusText"
android:layout_alignParentTop="true"
android:autoLink="web"
android:textColor="#android:color/white"
android:layout_toRightOf="#+id/statusImage" />
<TextView
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:textAppearance="?android:attr/textAppearanceSmall"
android:layout_below="#id/statusText"
android:text="Date"
android:id="#+id/statusDateText"
android:layout_alignBottom="#+id/statusImage"
android:layout_toRightOf="#+id/statusImage" />
Thanks.
