I know its too late to answer this question but for others who are searching for some thing similar to this here is a simple code of an alertbox with an edittext
AlertDialog.Builder alert = new AlertDialog.Builder(this);
or
new AlertDialog.Builder(mContext, R.style.MyCustomDialogTheme);
if you want to change the theme of the dialog.
final EditText edittext = new EditText(ActivityContext);
alert.setMessage("Enter Your Message");
alert.setTitle("Enter Your Title");
alert.setView(edittext);
alert.setPositiveButton("Yes Option", new DialogInterface.OnClickListener() {
public void onClick(DialogInterface dialog, int whichButton) {
//What ever you want to do with the value
Editable YouEditTextValue = edittext.getText();
//OR
String YouEditTextValue = edittext.getText().toString();
}
});
alert.setNegativeButton("No Option", new DialogInterface.OnClickListener() {
public void onClick(DialogInterface dialog, int whichButton) {
// what ever you want to do with No option.
}
});
alert.show();
