I want to dynamically set scrollbars in an EditText programmatically, but I don't find this api as setscrollbars. Could anyone tell me if this can be done programmatically?
android:scrollbars="vertical"
Is this possible? How can I achieve this programmatically?
I was looking for a method to do this programatically, too.
Seems from http://developer.android.com/reference/android/view/View.html#attr_android:scrollbars it's not possible, cause no related method is mentioned there.
The only method that sounds good by description is:
View.setVerticalScrollBarEnabled(boolean)
but in my case it didn't work. But that may depend on the layout and the way it is used.
I am thinking now about having two layouts: one with the attribute set to "none" and one set to "vertical". Then in code I could decide which to use.
final TypedArray typedArray = context.obtainStyledAttributes(null, new int[]{});
try {
Method method = View.class.getDeclaredMethod("initializeScrollbars" , TypedArray.class);
method.invoke(this, typedArray);
}catch (Exception e) {
}
typedArray.recycle();
setVerticalScrollBarEnabled(true);
You have to override the android:scrollbarTrackVertical and android:scrollbarThumbVertical drawables with your own. You can do it in code or with styling.
This is a link that shows how to do custom buttons. The principle for scrollbars is similar.
Programmatically :
RecyclerView mRecyclerView =rootView.findViewById(R.id.your-recycler-view);
if(mRecyclerView!=null){
mRecyclerView.setVerticalScrollBarEnabled( true );
}
In the XML :
<android.support.v7.widget.RecyclerView
android:layout_width="match_parent"
android:scrollbars="vertical"
android:layout_height="wrap_content" />
Other scrollbars:
android:scrollbars="vertical"
android:scrollbars="horizontal"
android:scrollbars="vertical|horizontal"
android:scrollbars="vertical" had to be in the XML for RecyclerView.setVerticalScrollBarEnabled to work.
