Create custom DialogPreference programmatically

Question

How can I create the dialog preference in code ?

        MyDialog dialog=new MyDialog(getActivity() );
        dialog.setTitle("asd");
        dialog.setKey("key");
        dialog.getDialog().show();

This is in my xml file, and it works fine when called prom preference screen

<!-- Custom Dialog -->
    <com.pak.asd.MyDialog
        android:key="key" android:title="title"
        android:dialogTitle="title"
        android:negativeButtonText="no"
        android:positiveButtonText="yes" android:dialogMessage="message" />

this is my class

public class MyDialog extends DialogPreference {
    private Context c;

    public MyDialog(Context c)
    {
    //is null correct ?
        super(oContext,null);       
        this.oContext = oContext;
    }

    public MyDialog(Context c, AttributeSet attrs)
    {
        super(c, attrs);        
        this.c = c;
    }

}

I see that the constructor is added now for API21, but will it throw an exception if we call `super(c,null)` in older platforms. What happened for your. — Samuel, Oct 28 '16 at 01:36

DialogPreference has no DialogPreference (Context context) constructor, so, why do you define a MyDialog(Context c) constructor? Usually, you don't need that constructor, just the second one.

I have never used DialogPreference before, but you should be able to create your custom class the same way as the base one.

What have you tried? Look for DialogPreference uses in Java code, I have never used it. Any example would fit for your extended class, don't worry for it. – thelawnmowerman Feb 14 '13 at 12:28
