android-为listview设置长按监听器

我有以下代码：

public class MainActivity extends ListActivity { 
protected void onCreate(Bundle savedInstanceState) {
    super.onCreate(savedInstanceState);
    setContentView(R.layout.activity_main);
}   
protected void onListItemClick(ListView l, View v, final int position, long id) {
    super.onListItemClick(l, v, position, id);
}}

我需要将其更改为onListItemLongClick(),但如何？可能吗？

解决方法:

您的问题与this one非常相似,但看起来并非完全相同.

您注意到的是ListActivity类没有专门针对这种情况的方法重写.

为了将此功能添加为方法覆盖,您的类应实现AdapterView.OnItemLongClickListener接口,然后可以添加onItemLongClick()方法覆盖,其作用与已具有的onListItemClick()方法覆盖相同,但会响应长按.

只要确保遵循this answer的说明,就必须在布局xml中使用android：longClickable =“ true”,或调用listview.setLongClickable(true);.

例：

public class MainActivity extends ListActivity implements AdapterView.OnItemLongClickListener {

    ListView listview;

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

        ListView listview = (ListView) findViewById(R.id.list);

        listview.setLongClickable(true);

    }

    @Override
    public boolean onItemLongClick(AdapterView<?> l, View v,
                                   final int position, long id) {

        Toast.makeText(this, "long clicked pos: " + position, Toast.LENGTH_LONG).show();

        return true;
    }

    protected void onListItemClick(ListView l, View v, final int position, long id) {
        super.onListItemClick(l, v, position, id);

        Toast.makeText(this, "short clicked pos: " + position, Toast.LENGTH_LONG).show();  

    }
