Android calling a custom ProgressDialog - how?

Question

How to center progress indicator in ProgressDialog easily (when no title/text passed along)

trying to create a custom progressdialog, but not working..

my code:

public class CustomProgressDialog extends ProgressDialog {

public CustomProgressDialog(Context context) {
        super(context, R.style.progress_dialog);
}

public static CustomProgressDialog show(Context context, CharSequence title,
        CharSequence message) {
    return show(context, title, message, false);
}

public static CustomProgressDialog show(Context context, CharSequence title,
        CharSequence message, boolean indeterminate) {
    return show(context, title, message, indeterminate, false, null);
}

public static CustomProgressDialog show(Context context, CharSequence title,
        CharSequence message, boolean indeterminate, boolean cancelable) {
    return show(context, title, message, indeterminate, cancelable, null);
}

public static CustomProgressDialog show(Context context, CharSequence title,
        CharSequence message, boolean indeterminate,
        boolean cancelable, OnCancelListener cancelListener) {
    CustomProgressDialog dialog = new CustomProgressDialog(context);
    dialog.setTitle(title);
    dialog.setCancelable(cancelable);
    dialog.setOnCancelListener(cancelListener);
    dialog.addContentView(new ProgressBar(context), new LayoutParams(LayoutParams.WRAP_CONTENT, LayoutParams.WRAP_CONTENT));
    dialog.show();

    return dialog;
}
}

and how i d like to call:

public static CustomProgressDialog dialog;

public static void showLoaderDialog(String sHead, String sMess) {
    dialog=new CustomProgressDialog(mycontext).show(mycontext, sHead, sMess, true, true);
}
public static void hideLoaderDialog() {
    dialog.dismiss();
}

but i get only crash:( why? how can call this custom dialog?

in the original post, Macarse extended his custom dialog from `Dialog`, not `ProgressDialog`. Maybe that's the problem? — bigstones, Apr 05 '11 at 19:23
@lacas have you solved this problem. If yes, please let me know how you solved it. — CrazyCoder, Apr 17 '12 at 08:00

Maybe, you should call dialog in this way:

public static void showLoaderDialog(String sHead, String sMess) {
  dialog=new CustomProgressDialog(mycontext);
  dialog.show(mycontext, sHead, sMess, true, true);
}

But I can be wrong.

Anyway, show, please, wich code line refers to CustomProgressDialog.java:37
