清除所有菜单选项<EditText>

Question

I am designing an app in Android Studio, but I am having trouble creating a clear option in the menu of my app.

Can someone show me how to add a menu option that will clear all the <EditText> items in my app I am creating?

You can try with below code and change the id of "your_group" with your main layout id.

ViewGroup group = (ViewGroup)findViewById(R.id.your_group);
for (int i = 0, count = group.getChildCount(); i < count; ++i) {
View view = group.getChildAt(i);
if (view instanceof EditText) {
    ((EditText)view).setText("");//here it will be clear all the EditText field
}
}

Please let me know if have any doubts.
