My custom adapter class is here. :

set_checked(check_value);
notifyDataSetChanged();
}
}
};
context.registerReceiver(receiver, new IntentFilter("master_check_change"));
set_checked(false);
}
// AS EVERY TIME LISTVIEW INFLATE YOUR VIEWS WHEN YOU MOVE THEM SO YOU NEED TO SAVE ALL OF YOUR CHECKBOX STATES IN SOME ARRAYLIST OTHERWISE IT WILL SET ANY DEFAULT VALUE.
private void set_checked(boolean is_checked)
{
for (int i=0; i < elements.length; i++) {
itemChecked.add(i, is_checked);
}
}
//THIS IS SIMPLY A CLASS VIEW WILL HOLD DIFFERENT VIEWS OF YOUR ROW.
static class ViewHolder

}
if (holder != null) {
holder.tv.setText(elements[position]);
holder.cb.setOnCheckedChangeListener(new OnCheckedChangeListener() {
#Override

}
});
if(position < itemChecked.size()) {
holder.cb.setChecked(itemChecked.get(position));

}
My activity class is here where i am create custom adapter object,
public class Test_stflowActivity extends Activity {
public CheckBox master_cb = null;
#Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.temp_layout);
String[] elements = new String[10];
for (int i = 0; i < 10; i++) {
elements[i] = "elements " + i;
}
CheckBox master_cb = new CheckBox(getApplicationContext());
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);

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....`

Is there a way for me to implement a listener on a button and upon clicking it, it leads me to the next activity?
thanks and sorry for the long post!

i was able to see upon clicking it but when i put an intent for it to
switch from one activity to another it came with errors. i only used
the log.d to find out whether the button work
startActivity is a method of Activity class. So you need Activity Context. You already have
this.context = context;
So Use
context.startActivity(new Intent(context, commentpage.class));

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.
