How to get all Views in an Activity?

Question

is there a way to get every view that is inside my activity? I have over 200 views including buttons, and images, so i want to be able to access them by using a loop

for example something like

for (View v : this)
{
     //do something with the views 
     //depending on the types (button, image , etc)
}

Get your root View, cast it to a ViewGroup, call getChildCount() and getChildAt(), and recurse as needed.

That is a rather large number of Views.

Solution 2

To be specific:

private void show_children(View v) {
    ViewGroup viewgroup=(ViewGroup)v;
    for (int i=0;i<viewgroup.getChildCount();i++) {
        View v1=viewgroup.getChildAt(i);
        if (v1 instanceof ViewGroup) show_children(v1);
        Log.d("APPNAME",v1.toString());
    }
}

And then use the function somewhere:

show_children(getWindow().getDecorView());

to show all Views in the current Activity.

Solution 3

Try to find all view associated with the Activity.

give the following command.

ViewGroup viewgroup=(ViewGroup)view.getParent();
viewgroup.getchildcount();

iterate through the loop.

We will get the Result.
