But scrollview doesn't work. Also I can't add scrollBar there, that seem doesn't work. I just looked some questions in StackOverflow. According them my codes should work. But it doesn't work. Please help me.

Inside ScrollView must contain only one layout!

This sample code solve your problem

<ScrollView xmlns:android="http://schemas.android.com/apk/res/android"
android:layout_width="match_parent"
android:layout_height="match_parent"
android:orientation="vertical">

  <LinearLayout
    android:layout_width="match_parent"
    android:layout_height="wrap_content"
    android:orientation="vertical">

     <!-- here add your views -->

   </LinearLayout>
</ScrollView>
