I am trying to add custom view inside Dialog preference, but I don't know how to override oncreatedialogview. Please help me.

@Override
protected View onCreateDialogView() {
    // TODO Auto-generated method stub
    LayoutInflater inflt = (LayoutInflater) context
            .getSystemService(Context.LAYOUT_INFLATER_SERVICE);
    View view = inflt.inflate(R.layout.numberpicker,null);
    if(view!=null){
        System.out.println("view error");
    }else{
        System.out.println("view ");
    }
    /*plus=(Button)view.findViewById(R.id.buttonplus1);
    minus=(Button)view.findViewById(R.id.buttonminus1);
    d   isplay=(TextView)view.findViewById(R.id.textView1);
    */return view;
}

The problem is that you're overriding the wrong class.

Here's the code we all want to make a new DialogPreference:

public class MyCustomPreference extends DialogPreference {

and like most of the time, we use the auto-complete to make sure we don't have any typing mistakes and to be nice and speedy programmers.

But Android Studio creates this import statement:

import androidx.preference.DialogPreference;

That's nice and all, but the AndroidX class does not have an onCreateDialogView() method.

Fortunately the fix is easy. Just delete the 'x' from the import statement, giving you:

import android.preference.DialogPreference;

Because of the many different libraries, this sort of issue is common, and will get more and more common as things keep changing.

You should not have to override the onCreateDialogView() method if you specify the resource in your DialogPreference class by calling setDialogLayoutResource(). For example:

public class NumberPickerPreference extends DialogPreference
{
    public NumberPickerPreference(Context context, AttributeSet attrs)
    {
        super(context, attrs);
        setDialogLayoutResource(R.layout.numberpicker);
    }
}

you can override the onCreateDialog method and add

Dialog dialog = new Dialog(getActivity());
dialog.setContentView(R.layout.layout);

return dialog;

inside it
