使用上下文菜单后获取选定的ListView项

<ListView
    android:id="@+id/listView"
    android:layout_width="match_parent"
    android:layout_height="match_parent"
    android:longClickable="true"
    android:onItemLongClickListener="onItemLongClick" />

public class MainActivity extends AppCompatActivity implements AdapterView.OnItemLongClickListener {
    private ListView listView;

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

        listView = findViewById(R.id.listView);
        listView.setOnItemLongClickListener(this);
    }

    @Override
    public boolean onItemLongClick(AdapterView<?> parent, View view, int position, long id) {
        // 在这里处理长按事件
        // 获取选中的ListView项
        Object selectedItem = listView.getItemAtPosition(position);
        
        // 进行相应的操作，如显示上下文菜单等
        
        return true; // 返回true表示消费了长按事件
    }
}
