Here, i have created a sample project related to ScrollView inside a ScrollView. One View is Scrollable Both ways. Check It Out :-

MainActivity.java -

package com.example.dev_task_193_scrollview;

import com.example.dev_task_196_scrollview.R;

import android.app.Activity;
import android.os.Bundle;
import android.view.Menu;
import android.view.MotionEvent;
import android.view.View;
import android.widget.AdapterView;
import android.widget.ArrayAdapter;
import android.widget.HorizontalScrollView;
import android.widget.ImageView;
import android.widget.ListView;
import android.widget.RelativeLayout;
import android.widget.ScrollView;
import android.widget.Toast;

public class MainActivity extends Activity implements View.OnClickListener{
    ImageView imageView1,imageView2,imageView3,IVimage1,IVimage2,IVimage3,IVimage4,IVimage5,IVimage6;
    ListView listView1,listView2;
    HorizontalScrollView horizontalScrollView1,horizontalScrollView2;
    ScrollView parentScrollView, scrollView1;
    RelativeLayout relativeLayout1;
    @Override
    protected void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.activity_main);
        String[] values = new String[] { "Android", "iPhone", "WindowsMobile",
                "Blackberry", "WebOS", "Ubuntu", "Windows7", "Max OS X",
                "Linux", "OS/2", "Ubuntu", "Windows7", "Max OS X", "Linux",
                "OS/2", "Ubuntu", "Windows7", "Max OS X", "Linux", "OS/2",
                "Android", "iPhone", "WindowsMobileWindowsMobileWindowsMobileWindowsMobile" };

        relativeLayout1 = (RelativeLayout) findViewById(R.id.relativeLayout1);
        imageView1 = (ImageView) findViewById(R.id.imageView1);
        imageView1.setBackgroundResource(R.drawable.info);

        imageView2 = (ImageView) findViewById(R.id.imageView2);
        imageView2.setBackgroundResource(R.drawable.info);

        imageView3 = (ImageView) findViewById(R.id.imageView3);
        imageView3.setBackgroundResource(R.drawable.info);

        listView1 = (ListView) findViewById(R.id.listView1);
        ArrayAdapter<String> adapter = new ArrayAdapter<String>(this,
