ListView inside ScrollView is not scrolling on Android

I am having trouble with a scrolling ListView inside a ScrollView. I have an Activity which has some EditTexts in the top part and then a tab host with two tabs which have one ListView each. When the EditText views are focused, the soft keyboard comes up and as I have a ScrollView, the content is scrollable. But the problem comes when there are more items in ListViews (ones in tabs), I am not able to scroll the ListView, even if there are more items.

The following is the layout XML:

<?xml version="1.0" encoding="utf-8"?>

<RelativeLayout
    xmlns:android="http://schemas.android.com/apk/res/android"
    android:layout_width="fill_parent"

              <ListView
                                android:cacheColorHint="#00000000"
                                android:id="@+id/ListView02"
                                android:layout_height="wrap_content"
                                android:layout_width="fill_parent" />

            </LinearLayout>


          </FrameLayout>
        </LinearLayout>
      </TabHost>
    </LinearLayout>
  </ScrollView>
</RelativeLayout>

Please can anyone tell me what the problem is here? I have another post on the ListView inside ScrollView problem, but they were of no use in my case.

I found a solution that works excellently and can scroll the ListView without problems:

ListView lv = (ListView)findViewById(R.id.myListView);  // your listview inside scrollview
lv.setOnTouchListener(new ListView.OnTouchListener() {
        @Override
        public boolean onTouch(View v, MotionEvent event) {
            int action = event.getAction();
            switch (action) {
            case MotionEvent.ACTION_DOWN:
                // Disallow ScrollView to intercept touch events.
                v.getParent().requestDisallowInterceptTouchEvent(true);
                break;

            case MotionEvent.ACTION_UP:
                // Allow ScrollView to intercept touch events.
                v.getParent().requestDisallowInterceptTouchEvent(false);
                break;
            }

            // Handle ListView touch events.
            v.onTouchEvent(event);
            return true;
        }
    });

What this does is disable the TouchEvents on the ScrollView and make the ListView intercept them. It is simple and works all the time.
