Can't make the onScrollChangeListener is it broken ?

Hi there,

I cant attach the listener to seekbar. How can i do it? I wanna change a textview to display the new seekbar value. My code is:

    DiscreteSeekBar seekBar = (DiscreteSeekBar)rootView.findViewById(R.id.seekBar);
    seekBar.setOnScrollChangeListener(new View.OnScrollChangeListener() {
        @Override
        public void onScrollChange(View v, int scrollX, int scrollY, int oldScrollX, int oldScrollY) {
            tvRange.setText("New value is "+scrollY);
        }
    });

And the error is :

4336-4336/com.developement.mt.langapp E/AndroidRuntime﹕ FATAL EXCEPTION: main Process: com.developement.mt.langapp, PID: 4336 java.lang.NoClassDefFoundError: com.developement.mt.langapp.SearchFragment$1 at com.developement.mt.langapp.SearchFragment.onCreateView(SearchFragment.java:37) at android.support.v4.app.Fragment.performCreateView(Fragment.java:1962) at android.support.v4.app.FragmentManagerImpl.moveToState(FragmentManager.java:1026) at android.support.v4.app.FragmentManagerImpl.moveToState(FragmentManager.java:1207) at android.support.v4.app.BackStackRecord.run(BackStackRecord.java:738) at android.support.v4.app.FragmentManagerImpl.execPendingActions(FragmentManager.java:1572) at android.support.v4.app.FragmentManagerImpl$1.run(FragmentManager.java:493) at android.os.Handler.handleCallback(Handler.java:808) at android.os.Handler.dispatchMessage(Handler.java:103) at android.os.Looper.loop(Looper.java:193) at android.app.ActivityThread.main(ActivityThread.java:5292) at java.lang.reflect.Method.invokeNative(Native Method) at java.lang.reflect.Method.invoke(Method.java:515) at com.android.internal.os.ZygoteInit$MethodAndArgsCaller.run(ZygoteInit.java:824) at com.android.internal.os.ZygoteInit.main(ZygoteInit.java:640) at dalvik.system.NativeStart.main(Native Method)
