I have tried the foll

Answer 1

This is an example dialog, create with xml.

the next code xml is just an example, the design or view is implemented here:

this lines of code are resources of drawable:

android:src="@drawable/dialog_cross"
android:background="@drawable/btn_flat_red_selector"

you could do a class extends Dialog, also something like this:

public class ViewDialog {

    public void showDialog(Activity activity, String msg){
        final Dialog dialog = new Dialog(activity);
        dialog.requestWindowFeature(Window.FEATURE_NO_TITLE);
        dialog.setCancelable(false);
        dialog.setContentView(R.layout.dialog);

        TextView text = (TextView) dialog.findViewById(R.id.text_dialog);
        text.setText(msg);

        Button dialogButton = (Button) dialog.findViewById(R.id.btn_dialog);
        dialogButton.setOnClickListener(new View.OnClickListener() {
            @Override
            public void onClick(View v) {
                dialog.dismiss();
            }
        });

        dialog.show();

    }
}

finally the form of call, on your Activity for example:

ViewDialog alert = new ViewDialog();
alert.showDialog(getActivity(), "Error de conexión al servidor");

I hope its work for you.
