Android : Unable to delete ListView item from menu

I am new here so please bear with my naivety. I am working on a music player that will display a menu on clicking 'dots' buttton(given in code below) in listview item. Inside the menu there will be a button to delete. The listview is getting populated by a custom adapter. Here is the code of adapter...
private class hashmapAdapter extends BaseAdapter implements Filterable {
HashMap<Integer, NowPlayingActivity.Details> NewDetails = new HashMap<>();
private hashmapAdapter(HashMap<Integer, NowPlayingActivity.Details> hashMap) {
if(NewDetails.size()==0) {
NewDetails.putAll(hashMap);
}
}
#Override
public int getCount() {
return NewDetails.size();
}
#Override
public Object getItem(int position) {
return NewDetails.get(position);
}
#Override
public long getItemId(int position) {
return position;
}
#Override
public View getView(final int position, View convertView, ViewGroup parent) {
final View result;
if(convertView == null) {
result = LayoutInflater.from(parent.getContext()).inflate(R.layout.single_item,parent,false);
} else {
result = convertView;
}
((TextView)result.findViewById(R.id.Name)).setText(NewDetails.get(position).getName());
((TextView)result.findViewById(R.id.artist)).setText(NewDetails.get(position).getArtist());
((TextView)result.findViewById(R.id.duration)).setText(NewDetails.get(position).getDuration()+" || ");
dots = (Button)result.findViewById(R.id.dots);
dots.setOnClickListener(new View.OnClickListener() {
#Override
public void onClick(View v) {
name = (TextView)result.findViewById(R.id.Name);
LayoutInflater inflater = (LayoutInflater)getSystemService(LAYOUT_INFLATER_SERVICE);
View popup_view = inflater.inflate(R.layout.option_layout,null);
RelativeLayout item = (RelativeLayout) popup_view.findViewById(R.id.popup);
final float width= (getResources().getDimension(R.dimen.width_entry_in_dp));
final float height= getResources().getDimension(R.dimen.height_entry_in_dp);
final PopupWindow popupWindow = new PopupWindow(popup_view,Math.round(width),Math.round(height),true);
popupWindow.showAtLocation(item, Gravity.END, 0, 0);
popupWindow.showAsDropDown(dots);
play_next_btn = (Button)popup_view.findViewById(R.id.play_next);
add_to_playlist = (Button)popup_view.findViewById(R.id.add_to_playlist);
share = (Button)popup_view.findViewById(R.id.share);
delete = (Button)popup_view.findViewById(R.id.delete);
delete.setOnClickListener(new View.OnClickListener() {
#Override
public void onClick(View v) {
for(int i=0;i<NewDetails.size();i++) {
if(NewDetails.get(i).getName().equals(name.getText().toString())) {
for(int j=0;j<hashMap.size();j++) {
if(hashMap.get(j).getName().equals(name.getText().toString())) {
if (true) {
NewDetails.remove(i);
hashMap.remove(j);
}
}
}
}
}
populate1(NewDetails);
popupWindow.dismiss();
}
});
}
});
return result;}
Now the problem is that after deleting element when i call populate1(NewDetails), it gives a null pointer exception on NewDetails.get(position).getName(). So on repopulating listview i am getting NPE error. Following is the populate1() function code...
public void populate1(HashMap<Integer,NowPlayingActivity.Details> hashMap) {
adapter = new hashmapAdapter(hashMap);
library.setAdapter(adapter);
adapter.notifyDataSetChanged();
library.setOnItemClickListener(new AdapterView.OnItemClickListener() {
#Override
public void onItemClick(AdapterView<?> parent, View view, int position, long id) {
name = (TextView)view.findViewById(R.id.Name);
String SongName = name.getText().toString();
Intent intent = new Intent(getApplicationContext(),NowPlayingActivity.class);
intent.putExtra("SongName",SongName);
setResult(555,intent);
finish();
}
});
}
I have already tried notifydatasetchanged() and listview.invalidateviews(), both didnt work. File is getting deleted but the adapter is not refreshing the list to remove element. Here is the xml layout of single_item for listview....`

The height of ExpandableListView impacts the display of ChildView

I have searched for this issue a few days. Here's the structure of the app.

Here's the behavior: when clicking the group header, no child view is displayed. From LogCat, I can see that getViewGroup() in the adapter is called twice though, but getChildView() is not called at all. After searching the internet and trying them out, I still can't get the child view displayed when clicking on the group header, but when I tried setting the ExpanandableListView height with a fix height, say, 400dp, like this:
<ExpandableListView xmlns:
android:layout_width="match_parent"
android:layout_height="400dp"
android:id="#+id/expLVClaims"/>
the child view is then expanded and collapsed as expected. But the thing is that because the fixed height will makes the ExpandableListView occupy 400dp space vertically, even no data is in the adapter at all, which is unwanted behavior.
Can someone throw some hints?
Thanks in advance!

First thing:
You should not use any scrolling component like expandable list, inside a scroll view here's why Listview inside ScrollView is not scrolling on Android.
Second thing:
Height of ExpandableListView should be match_parent.
I was also facing the same problem related to height, and making ExpandableListView height as match_parent resolved my problem. I think this will help you.

Spinner Visibility

I've a strange problem with my custom spinner. My implementation is to hide the spinner and only fire the choices whenever i click a button so my spinner visibility is set to INVISIBLE and only fire a list of choices and assign the selected value back to a TextView. My code works only in emulator but when i went to my actual device the list of choices is not opened and only the default value is selected back to my textview. I've tried to set spinner visibility to Visible. This time i got the choices. I remember i have another implementation with the visibility is set to INVISIBLE and it worked as desired. Any clues?

It's not possible to make a scrollable view inside a scrollable view. But as a work around this, and only in case that this listviews doesn't take much memory if all views are loaded.
you can use this
import android.content.Context;
import android.util.AttributeSet;
import android.widget.ListView;
public class NonScrollableListView extends ListView {
public NonScrollableListView(Context context, AttributeSet attrs) {
super(context, attrs);
}
#Override
protected void onMeasure(int widthMeasureSpec, int heightMeasureSpec) {
// Do not use the highest two bits of Integer.MAX_VALUE because they are
// reserved for the MeasureSpec mode
int heightSpec = MeasureSpec.makeMeasureSpec(Integer.MAX_VALUE >> 2, MeasureSpec.AT_MOST);
super.onMeasure(widthMeasureSpec, heightSpec);
getLayoutParams().height = getMeasuredHeight();
}
}
Again, it's not good to use this workaround
you will use this non Scrollable listview in the child.xml layout by adding it as a customized UI component
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
xmlns:tools="http://schemas.android.com/tools"
android:layout_width="match_parent"
android:layout_height="match_parent"
android:orientation="vertical" >
<com.youpackage.uiutils.NonScrollableListView
android:id="#+id/non_scrollable_listview"
android:layout_width="wrap_content"
android:layout_height="wrap_content"/>
</LinearLayout>

You can ExpandableListView in place of making custom view also for data handling you can use ExpandableListAdapter.

UI in Graphical Layout and in device are not the same [Android]

ListView in Graphical Layout is fit on appropriate height but when i imported into android device, ListView is reduced in a small field. i want ListView are the same in Graphical Layout in xml file and in real device screen

I have tried to modify your layout. Try this may be it will be helpful for you.. just create a new xml layout file and check it is working for you or not.

master_cb.setText("Check All");
//HERE IS THE LIST VIEW WHICH I HAVE CREATED IN MY XML FILE.
ListView lv = (ListView) findViewById(R.id.listView1);
//HERE I AM CREATING CUSTOM ADAPTER OBJECT.
my_custom_adapter adapter = new my_custom_adapter(this, android.R.layout.simple_list_item_1, elements);
lv.addHeaderView(master_cb);
