android listview监听事件,android-为listview设置长按监听器

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();

}
