its working for me

Dialog m_dialog; 
m_dialog = new Dialog(BusinessDetail.this);
            m_dialog.requestWindowFeature(Window.FEATURE_NO_TITLE);
            
            LayoutInflater m_inflater = LayoutInflater.from(BusinessDetail.this);
            View m_view = m_inflater.inflate(R.layout.rateus_popup, null);
            myPopLay = (LinearLayout) m_view.findViewById(R.id.myPopLay);
m_dialog.setContentView(m_view);
            m_dialog.show();

Answer 3

you can use Dialog , like this code :

final Dialog dialog = new Dialog(context);
// dialog.requestWindowFeature(Window.FEATURE_NO_TITLE);
dialog.setContentView(R.layout.custom);
dialog.setTitle("Title...");

// set the custom dialog components - text, image and button
TextView text = (TextView) dialog.findViewById(R.id.text);
text.setText("Android custom dialog example!");
Button dialogButton = (Button) dialog.findViewById(R.id.dialogButtonOK);
// if button is clicked, close the custom dialog
dialogButton.setOnClickListener(new OnClickListener() {
@Override
public void onClick(View v) {
dialog.dismiss();
}
});
dialog.show();

if you want to remove title bar just use this code after define :

dialog.requestWindowFeature(Window.FEATURE_NO_TITLE);
