我想在短暂的一次点击时使用setMultiChoiceModeListener。 但它只有在长时间点击时才有效..如何短暂点击一下设置工作setMultiChoiceModeListener？
例如：＆＃34; Root Explorer＆＃34;应用程序执行此操作。
public class FavoritesActivity extends AppCompatActivity {
private ListView listView;
private ArrayList<FavoritesList> favList;
private FavoritesAdapter favAdapter;
private int checkedCount;
@Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_favorites);
DBHandler dbhandler = DBHandler.open(this);
Cursor cursorFav = dbhandler.selectFav();
favList = new ArrayList<FavoritesList>();
if (cursorFav.getCount() != 0) {
while (cursorFav.moveToNext()) {
String no = cursorFav.getString(cursorFav.getColumnIndex(DBHelper.FAV_COL_1));
String title = cursorFav.getString(cursorFav.getColumnIndex(DBHelper.FAV_COL_2));
String page = cursorFav.getString(cursorFav.getColumnIndex(DBHelper.FAV_COL_3));
favList.add(new FavoritesList(no, title, page));
}
listView = (ListView) findViewById(R.id.fav_listview);
favAdapter = new FavoritesAdapter(this, R.layout.activity_favorites_entry, favList);
listView.setAdapter(favAdapter);
final boolean[] delete_status = {false};
listView.setChoiceMode(ListView.CHOICE_MODE_MULTIPLE_MODAL);
listView.setMultiChoiceModeListener(new AbsListView.MultiChoiceModeListener() {
@Override
public void onItemCheckedStateChanged(ActionMode mode, int position, long id, boolean checked) {
checkedCount = listView.getCheckedItemCount();
mode.setTitle(checkedCount + " Selected");
favAdapter.toggleSelection(position);
}
@Override
public boolean onCreateActionMode(ActionMode mode, Menu menu) {
mode.getMenuInflater().inflate(R.menu.favorites, menu);
return true;
}
@Override
public boolean onPrepareActionMode(ActionMode mode, Menu menu) {
return false;
}
@Override
public boolean onActionItemClicked(ActionMode mode, MenuItem item) {
SparseBooleanArray selected = favAdapter.getSelectedIds();
switch (item.getItemId()) {
case R.id.action_check_all:
if (selected.size() != favList.size()) {
favAdapter.removeSelection();
checkedCount = favList.size();
mode.setTitle(checkedCount + " Selected");
for (int i = 0; i < favList.size(); i++) {
listView.setItemChecked(i, true);
}
}
return true;
case R.id.action_delete:
DBHandler dbhandler = DBHandler.open(FavoritesActivity.this);
for (int i = (selected.size() - 1); i >= 0; i--) {
FavoritesList selectedItem = favAdapter.getItem(selected.keyAt(i));
favAdapter.remove(selectedItem);
dbhandler.deleteFav(selectedItem.getNo_int());
}

回答我自己的问题...... 只需在FavoritesActivity.java中添加setOnItemClickListener
listView.setOnItemClickListener(new AdapterView.OnItemClickListener() {
@Override
public void onItemClick(AdapterView<?> parent, View view, int position, long id) {
listView.setItemChecked(position, !favAdapter.getItem(position).getChecked());
}
});
