How to achive such a Popup in android

Can someone tell me how to implement this in an android app. If you can share code, some reference, or a tutorial. Anything will be helpful

You can inflate your custom layout to popup window.
LayoutInflater layoutInflater = (LayoutInflater)getBaseContext(.getSystemService(LAYOUT_INFLATER_SERVICE);
View popupView = layoutInflater.inflate(R.layout.popup, null);
final PopupWindow popupWindow = new PopupWindow(popupView,400,400);
popupWindow.showAtLocation(attachment_button, Gravity.CENTER, 10, 200);
Take custom listview in your layout.

You can do this with Dialog that would show when you click at filter_box.
Just create class MyDialog extends Dialog and place your xml layout the place you need "popup" show.

how to add custom views to alertdialog in android?

I am trying to add custom views(chekbox and two radio buttons) as shown in image below in alertdialog but not succeded.
Please suggest me a way to get views as shown in the image.
Thanks in advance!!

Use DialogFragment instead of AlertDialog.
public class CustomDialogFragment extends DialogFragment {
#NonNull
#Override
public Dialog onCreateDialog(Bundle savedInstanceState) {
AlertDialog.Builder builder = new AlertDialog.Builder(getActivity());
LayoutInflater inflater = LayoutInflater.from(getActivity());
View viewRoot = inflater.inflate(R.layout.dialog_view, null);
//do something with your view
builder.setView(viewRoot);
return builder.create();
}
}
R.layout.dialog_view - it's your view, which you want to display

You can build dialog with custom layout. Here's some tutorial how to do that:

How center custom dialog title on Android

I'm writing a custom dialog on android.
I did this using the onCreateView method.
public class CheckpointLongPressDialog extends DialogFragment {
public void CheckpointLongPressDialog() {}
#Nullable
#Override
public View onCreateView(LayoutInflater inflater, ViewGroup container, Bundle savedInstanceState) {
View view = inflater.inflate(R.layout.fragment_checkpoint_long_press_dialog, container);
getDialog().setTitle("TITLE");
return view;
}
How can i center the title programmatically?

Maybe its not the best way, I use a custom title TextView.
TextView title = new TextView(mainActivity);
title.setText(alertTitle);
title.setBackgroundResource(R.drawable.gradient);
title.setPadding(10, 10, 10, 10);
title.setGravity(Gravity.CENTER); // this is required to bring it to center.
title.setTextSize(22);
getDialog().setCustomTitle(title);

I solve the problem using a builder and inflating the xml layout.
private AlertDialog.Builder builder;
#Override
public Dialog onCreateDialog(Bundle savedInstanceState) {
// Use the Builder class for convenient dialog construction
builder = new AlertDialog.Builder(getActivity());
LayoutInflater inflater = getActivity().getLayoutInflater();
builder.setView(inflater.inflate(R.layout.fragment_checkpoint_long_press_dialog, null));
// Create the AlertDialog object and return it
return builder.create();
}

Try this..
final int titleId = getActivity().getResources().getIdentifier("alertTitle", "id", "android");
TextView title = (TextView) getDialog().findViewById(titleId);
if (title != null) {
title.setGravity(Gravity.CENTER);
}

What if you use the whole layout to inflate also your custom title?. Instead of getDialog().setTitle("TITLE"); you can also include a TextView in your custom layout for the title.

The title view is using default theme. You have 2 ways to do what you want, first one is better for having a more customized experience:
Use this to have a dialog without title, and then make custom title bar in the layout of this fragment.
dialog.getWindow().requestFeature(Window.FEATURE_NO_TITLE);
Extend the default theme for the dialog and update it, then set it in this dialog.

Create AlertDialog using inside layout of a xml

I want to create a alert dialog using a layout which is in a xml. I tried this:
AlertDialog.Builder builder = new AlertDialog.Builder(this);
LayoutInflater inflater = getLayoutInflater();
View v = inflater.inflate(R.id.optionsmenu, null);
AlertDialog dialog = builder.setView(v).create();
dialog.show();
It does not work. optionsmenu is the layout that i want to use to create alert dialog. Can i set alert dialog view to this inner layout ?
here is the image's url . You can see the layout that i want to use.

I dont really know how you expect your dialog to look like but you should create it like this:
Dialog dialog = new Dialog(this);
dialog.setContentView(R.layout.activity_main);
dialog.setTitle("");
//to use a view inside the xml (i.e. a button)
Button button = (Button)dialog.findViewById(R.id.optionsmenu);
dialog.show();
Note that you were trying to inflate not the layout but the view (R.id.optionsmenu) it should have been (R.layout.activity_main)
alertDialog.builder is used to create a dialog without using a xml layout

How can I customize the header layout of a dialog

In Android, is it possible to customize the header layout (the icon + a text) layout of a dialog? Or can I just set a custom string value of the title text?
Thank you.

It's possible to change the header of the Dialog if you set a custom layout for both the dialog and the header. I've only ever used this method to remove the header entirely, but this ought to work for a custom header:
dialog = new Dialog(context);
Window window = dialog.getWindow();
window.requestWindowFeature(Window.FEATURE_CUSTOM_TITLE);
dialog.setContentView(R.layout.my_dialog_layout);
window.setFeatureInt(Window.FEATURE_CUSTOM_TITLE, R.layout.my_custom_header);
This is all a tad more complicated (as you have to setup the dialog's layout as well) but it's easier than subclassing Dialog.

the original Dialog class seems to lack the ability to set an icon, but you can easily extend AlertDialog and set a custom view (the same you would use for your Dialog instance), you just need something like this
class MyDialog extends AlertDialog {
public MyDialog(Context ctx) {
super(ctx);
LayoutInflater factory = LayoutInflater.from(context);
View view = factory.inflate(R.layout.dialog_layout, null);
setView(view);
setTitle("MyTitle");
setIcon(R.drawable.myicon);
}
}
