Creating Custom Dialog from Layout File

In this post, I will show how to create a custom dialog using xml layout file.

First you have to create a xml layout file. After creating layout file than you have to open activity in which you want to display dialog. Here, layout file contains a button "OK" as an example.

In the activity, declare the Dialog and than create a method as below:

private Dialog myDialog;

private void showDialog() { 

myDialog = new Dialog(this,R.style.wideDialogStyle);

myDialog.setCancelable(false);

myDialog.setCanceledOnTouchOutside(false);

myDialog.getWindow().setLayout(ViewGroup.LayoutParams.WRAP_CONTENT,

    ViewGroup.LayoutParams.WRAP_CONTENT);

myDialog.requestWindowFeature(Window.FEATURE_NO_TITLE);

myDialog.setContentView(R.layout.log_in);

myDialog.show(); 

// Set up the Button

okBtn = (Button) myDialog.findViewById(R.id.ok_btn); okBtn.setOnClickListener(okBtnListener); 

} 

//This is the onClickListener() for OK button of the Dialog
private Button.OnClickListener okBtnListener = new Button.OnClickListener() { 
@Override 
public void onClick(View v) { 

myDialog.dismiss();

}
