Why Is My Custom Alert Dialog Code Crashing?

Question

I'm trying to apply custom view to alert dialog. I'm doing like this, but there is nullpointer exception when I try to show the alert box. I create a layout.xml like so:

Solution 1:

public class BranchDialog extends android.app.Dialog
{

    ListView list;
    Context context;
    TextView title; 
    ProgressBar progress;

    public BranchDialog(Context context, String rid, String name) 
    {
        super(context);

        setContentView(R.layout.branch_dialog);
        setCancelable(true);
        setTitle(name);
        this.context = context;

        title = (TextView)findViewById(R.id.branch_dialog_title);

        title.setText("this is my custom title");
        show();
    }

}

may be help full for you after a bit changing.
