How do I open different actions on my list items?

I have a String-Array with 9 different strings and created a listView with these Strings; Now I would like to open another activity when I click on each item in my listView. I've already tried

row.setOnClickListener(new View.OnClickListener() {
    @Override
    public void onClick(View v) {
        startActivity(new Intent((Activity)context, Workouts.class));
    }
});

      

        
        
        
      

    

But it only opens one action for all elements. It would be really nice if you could provide me with a working code, because I already tried to solve this problem.

MainActivity:

public class MainActivity extends Activity implements OnItemClickListener {

    private DrawerLayout drawerLayout;
    private ListView listView;

    private ActionBarDrawerToggle drawerListener;
    private MyAdapter MyAdapter;

    @Override
    protected void onCreate(Bundle savedInstanceState){

        super.onCreate(savedInstanceState);

        setContentView(R.layout.activity_main);
        drawerLayout=(DrawerLayout) findViewById(R.id.drawerLayout);

        listView=(ListView)findViewById(R.id.drawerList);
        MyAdapter=new MyAdapter(this);
        listView.setAdapter(MyAdapter);
        listView.setOnItemClickListener(this);

        drawerListener= new ActionBarDrawerToggle(this, drawerLayout,     
        R.drawable.listmenu,
        R.string.drawer_open, R.string.drawer_close){

            @Override
            public void onDrawerClosed(View drawerView) {
                // TODO Auto-generated method stub
                super.onDrawerClosed(drawerView);
            }

            @Override
            public void onDrawerOpened(View drawerView) {
                // TODO Auto-generated method stub
                Toast.makeText(MainActivity.this, " Drawer Opened ",   
                Toast.LENGTH_SHORT).show();
            }

        };

        drawerLayout.setDrawerListener(drawerListener); 

        getActionBar().setHomeButtonEnabled(true);
        getActionBar().setDisplayHomeAsUpEnabled(true);
    }

    @Override
    public boolean onOptionsItemSelected(MenuItem item) {
        // TODO Auto-generated method stub

        if (drawerListener.onOptionsItemSelected(item))
        {
            return true;
        }

        return super.onOptionsItemSelected(item);
    }

    @Override
    public void onConfigurationChanged(Configuration newConfig) {
        // TODO Auto-generated method stub
        super.onConfigurationChanged(newConfig);

        drawerListener.onConfigurationChanged(newConfig);
    }


    @Override
    protected void onPostCreate(Bundle savedInstanceState) {
        // TODO Auto-generated method stub
        super.onPostCreate(savedInstanceState);
        drawerListener.syncState();
    }

    @Override
    public void onItemClick(AdapterView<?> parent, View view, int position,        
    long id) {
    }

    public void selectItem(int position) {        
        listView.setItemChecked(position, true);
    }

    public  void setTitle(String title)
    {
        getActionBar().setTitle(title);

    class MyAdapter extends BaseAdapter {
        private Context context;
        String[] planets;

        int[] images = { R.drawable.home, R.drawable.workout, R.drawable.week,
            R.drawable.gallery, R.drawable.statistics, R.drawable.settings};

            public MyAdapter(Context context) {
                this.context=context;
                planets=context.getResources().getStringArray(R.array.planets);
            }

            @Override
            public int getCount() {
                // TODO Auto-generated method stub
                return planets.length;
            }

            @Override
            public Object getItem(int position) {
                // TODO Auto-generated method stub
                return planets[position];
            }

            @Override
            public long getItemId(int position) {
                // TODO Auto-generated method stub
                return position;
            }

            @Override
            public View getView(int position, View convertView, ViewGroup parent) {
                // TODO Auto-generated method stub

                View row =null;

                if (convertView==null)
                {
                    LayoutInflater inflater = (LayoutInflater)            
                        context.getSystemService(Context.LAYOUT_INFLATER_SERVICE);

                    row=inflater.inflate(R.layout.custom_row, parent, false);
                }
                else
                {
                    row = convertView                    
                }

                row.setOnClickListener(new View.OnClickListener() {
                    @Override
                    public void onClick(View v) {
                        startActivity(new Intent((Activity) context, Workouts.class));
                    }
                });

                TextView titleTextView = (TextView) row.findViewById(R.id.textView1);
                ImageView titleImageView = (ImageView) row.findViewById(R.id.imageView1);

                titleTextView.setText(planets[position]);
                titleImageView.setImageResource(images[position]);
                return row;
