Is there anyway to find out what type of View a View is?

Question

So if I were to have a LinearLayout and had several children Views inside of it, say like a couple of Buttons a TextView and a CheckBox, using the LinearLayout's getChildAt(x) I would then get an unspecified View. To note, I'm not using an xml in this so it's all done programatically.

public class CustomViewClass extends LinearLayout {

    private Context context;

    public CustomViewClass (Context context) {
        super(context);
        this.context = context;
        setOrientation(LinearLayout.VERTICAL);
        setLayoutParams(new LayoutParams(LayoutParams.MATCH_PARENT, LayoutParams.MATCH_PARENT));
        setBackgroundColor(Color.DKGRAY);
        // Code which adds Buttons and such to the LinearLayout
        getChildAt(1)
    }

}

The getChildAt(1), is there anyway that I can find out what kind of View it is, whether it's a Button or a TextView or whatever progamatically?

Answer 1

One way to do this is to call getClass. This will get you a Class object representing the type of view.

For example:

Class clazz = getChildAt(1).getClass();

After you have the class, you can do all kinds of things with it. e.g. get the name:

System.out.println(clazz.getName());

Now you know what kind of view it is.

Another way is to use the instanceof operator. Here's an example:

if (getChildAt(1) instanceof TexView) {
    // getChildAt(1) is a TextView or an instance of a subclass of TextView
}

Answer 2

Use instanceOf method. Sample example is

if (view instanceof ImageView) 

Or You can use below to find out the type of view. But if you want to do any computation on it, instance of is the best choice.

view.getClass

if (view.getClass().getName().equalsIgnoreCase("android.widget.ImageView"))
