【问题描述】：

我有一个带有列表视图的搜索视图。我把一些项目打开一个新的活动。当我在第一个活动中时，好吧。但是，如果我在 Searchview 上搜索另​​一个项目，应用程序会服从该位置。然后，选择了错误的项目。 我怎样才能通过字符串使项目点击工作？

我的代码：

public class MainActivity extends ListActivity 

    ListView lv;
    SearchView sv;
    String[] teams="Activity 1","Activity 2","Activity 3","Activity 4","Activity 5","Activity 6";
    ArrayAdapter<String> adapter;


    @Override
    protected void onCreate(Bundle savedInstanceState) 
        super.onCreate(savedInstanceState);
        setContentView(R.layout.activity_main);

        lv=(ListView) findViewById(android.R.id.list);
        sv=(SearchView) findViewById(R.id.searchView);
        adapter=new ArrayAdapter<String>(this, android.R.layout.simple_list_item_1,teams);
        lv.setAdapter(adapter);

                sv.setOnQueryTextListener(new SearchView.OnQueryTextListener() 
                    @Override
                    public boolean onQueryTextSubmit(String text) 
                        return false;
                    

                    @Override
                    public boolean onQueryTextChange(String text) 
                        adapter.getFilter().filter(text);
                        return false;
                    
                );

    

    @Override
    //to open new activity
    protected void onListItemClick(ListView l, View v, int position, long id) 
        super.onListItemClick(l, v, position, id);
        if (position == 0) 
            Intent intent = new Intent(this, Main2Activity.class);
            startActivity(intent);
         else if (position == 1) 
            Intent intent = new Intent(this, Main3Activity.class);
            startActivity(intent);
         
        
    


    @Override
    public boolean onCreateOptionsMenu(Menu menu) 
        // Inflate the menu; this adds items to the action bar if it is present.
        getMenuInflater().inflate(R.menu.menu_main, menu);
        return true;
    

    @Override
    public boolean onOptionsItemSelected(MenuItem item) 
        // Handle action bar item clicks here. The action bar will
        // automatically handle clicks on the Home/Up button, so long
        // as you specify a parent activity in AndroidManifest.xml.
        int id = item.getItemId();

        //noinspection SimplifiableIfStatement
        if (id == R.id.action_settings) 
            return true;
        

        return super.onOptionsItemSelected(item);
