从带有contextmenuinfo的listView中获取字符串

Question

我有一个来自Android应用程序的项目，我希望当我点击contextMenu中的选项时，我会看到该位置的字符串。

String[] datos = {"Victor","Silvia","Manolo","Carlos","Ana"};
        ArrayAdapter<String> adaptador = new ArrayAdapter<String>(this,android.R.layout.simple_list_item_1, datos);

    milista.setAdapter(adaptador);

这是通过单击上下文菜单的内容来执行某些操作的方法

 @Override
public boolean onContextItemSelected(MenuItem item) {

    AdapterView.AdapterContextMenuInfo info = (AdapterView.AdapterContextMenuInfo) item.getMenuInfo();
    switch (item.getItemId()){

        case R.id.action_mostrar:
            Toast.makeText(getApplicationContext(),info.position+": Opción mostrar" , Toast.LENGTH_LONG).show();
            return true;

        case R.id.action_eliminar:
            Toast.makeText(getApplicationContext(), info.position+": Opción eliminar", Toast.LENGTH_LONG).show();
            return true;

        default:
            return false;

    }
}

我该怎么做？

修改

问题解决了，我把代码解决了：

@Override
    public boolean onContextItemSelected(MenuItem item) {

        AdapterView.AdapterContextMenuInfo info = (AdapterView.AdapterContextMenuInfo) item.getMenuInfo();

        String selectedWord = ((TextView) info.targetView).getText().toString();
        switch (item.getItemId()){

            case R.id.action_mostrar:
                Toast.makeText(getApplicationContext(),selectedWord+": Opción mostrar" , Toast.LENGTH_LONG).show();
                return true;

            case R.id.action_eliminar:
                Toast.makeText(getApplicationContext(), selectedWord+": Opción eliminar" , Toast.LENGTH_LONG).show();
                return true;

            default:
                return false;

        }
    }

谢谢

您也可以使用该位置从字符串数组中检索字符串，如下所示

@Override
    public boolean onContextItemSelected(MenuItem item) {

        AdapterView.AdapterContextMenuInfo info = (AdapterView.AdapterContextMenuInfo) item.getMenuInfo();

        switch (item.getItemId()){

            case R.id.action_mostrar:
                Toast.makeText(getApplicationContext(),datos[info.position]+": Opción mostrar" , Toast.LENGTH_LONG).show();
                return true;

            case R.id.action_eliminar:
                Toast.makeText(getApplicationContext(), datos[info.position]+": Opción eliminar" , Toast.LENGTH_LONG).show();
                return true;

            default:
                return false;

        }
    }
