Java 如何使用我的listView项目打开不同的活动？

我有一个包含9个不同字符串的字符串数组，并用这些字符串创建了一个listView；现在我想在单击listView的每个元素时打开一个不同的活动。我已经试过了

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

但它只为所有项目打开相同的活动。如果您能提供一个工作代码，那将是非常好的，因为我已经尝试过处理这个问题

主要活动：

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();
    }

row.setOnClickListener(new View.OnClickListener() {

         Switch(position){


         case 0:

         case 1:

              break;

    }
