Question

From the official documentation:

A subclass of Dialog that can display one, two or three buttons. If
you only want to display a String in this dialog box, use the
setMessage() method. If you want to display a more complex view, look
up the FrameLayout called “custom” and add your view to it:

 FrameLayout fl = (FrameLayout) findViewById(android.R.id.custom);
 fl.addView(myView, new LayoutParams(MATCH_PARENT, WRAP_CONTENT));

But the problem is that android.R.id.custom presents only in OS from 8 API Level.

How can I make custom AlertDialog if I work with less API Level?

Answer 1

actually what you do is as follows:

first, you create the custom_layout.xml under res/layout.
then you’ll add the next code to your activity

Dialog myDialog = new Dialog(this);
myDialog .setOwnerActivity(MyParentActivity.this);
myDialog .setContentView(R.layout.custom_layout);
myDialog .setTitle("title");

and you can show and dismiss it usingmyDialog.show(); and myDialog.dismiss();

if you have buttons or other views inside your custom_layout.xml, you can find them by

Button myButton = (Button) myDialog.findViewById(R.id.myButton);

I hope this helps.
