I think the preferred way is to use action mode for these types of menus. 我认为首选的方法是对这些类型的菜单使用动作模式。 Take a look at this I think this will have all the info you need. 看看这个,我想这将包含您需要的所有信息。 It seems a bit overwhelming, but it's not that bad to implement. 这看起来有点压倒性,但实施并不是那么糟糕。 http://developer.android.com/guide/topics/ui/menus.html http://developer.android.com/guide/topics/ui/menus.html
Try to use pop menu like this.. 尝试使用像这样的弹出菜单..
public class MainActivity extends Activity {
@Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);
Button button = (Button) findViewById(R.id.button2);
registerForContextMenu(button);
}
@Override
public void onCreateContextMenu(ContextMenu menu, View v,
ContextMenuInfo menuInfo) {
super.onCreateContextMenu(menu, v, menuInfo);
getMenuInflater().inflate(R.menu.main, menu);
}
public void showPopup(View v) {
PopupMenu popup = new PopupMenu(this, v);
getMenuInflater().inflate(R.menu.main, popup.getMenu());
popup.show();
popup.setOnMenuItemClickListener(new OnMenuItemClickListener() {
@Override
public boolean onMenuItemClick(MenuItem arg0) {
Toast.makeText(MainActivity.this, "" + arg0, Toast.LENGTH_SHORT)
.show();
return false;
}
});
}
@Override
public boolean onCreateOptionsMenu(Menu menu) {
// Inflate the menu; this adds items to the action bar if it is present.
getMenuInflater().inflate(R.menu.main, menu);
return true;
}
} }
And xml like this.. 和xml这样..
<menu xmlns:android="http://schemas.android.com/apk/res/android" >
<item
android:id="@+id/edit"
android:title="edit"/>
<item
android:id="@+id/delete"
android:title="delete"/>
<item
android:id="@+id/exit"
android:title="exit"/>
Try this below code.. 试试以下代码..
in java 在java中
listView.setOnItemLongClickListener(new OnItemLongClickListener()
{
@Override
public boolean onItemLongClick(AdapterView<?> arg0, View v,
int position, long id) {
// TODO Auto-generated method stub
LayoutInflater layoutInflater= (LayoutInflater)getBaseContext().getSystemService(LAYOUT_INFLATER_SERVICE);
final View popupView = layoutInflater.inflate(R.layout.list_popup, null);
final PopupWindow popupWindow = new PopupWindow(popupView,155,LayoutParams.WRAP_CONTENT);
ListView listView = (ListView) popupView.findViewById(R.id.list_view);
listView.setAdapter(new ArrayAdapter<String>(getApplicationContext(), android.R.layout.simple_list_item_1,menu));
popupWindow.showAsDropDown(listView, 50, 0);
