how to check listitem is checked or not in listview android?
i have listview which is multiple choice mode
lView = (ListView) findViewById(R.id.ListView01);
lView.setAdapter(new ArrayAdapter<String>(this,android.R.layout.s开发者_如何转开发imple_list_item_multiple_choice, lv_items));
lView.setChoiceMode(ListView.CHOICE_MODE_MULTIPLE);
this contains multiple choice list items i want to check whether selected item is checked or not so how i can do that.
You need to grab the items that have been clicked and then iterate through them to find the checked ones like so:
// Using a List to hold the IDs, but could use an array.
List<Integer> checkedIDs = new ArrayList<Integer>();
// Get all of the items that have been clicked - either on or off
final SparseBooleanArray checkedItems = lView.getCheckedItemPositions();
for (int i = 0; i < checkedItems.size(); i++){
// And this tells us the item status at the above position
final boolean isChecked = checkedItems.valueAt(i);
if (isChecked){
// This tells us the item position we are looking at
final int position = checkedItems.keyAt(i);
// Put the value of the id in our list
checkedIDs.put(position);
}
}
Note the getCheckedItemPositions() gets the items that have been checked by the user regardless if the checkbox was left checked or not.
I used the isChecked property of the given list item when clicked:
protected void onListItemClick(ListView l, View v, int position, long id) {
CheckedTextView item = (CheckedTextView)v;
if(item.isChecked()){
//do what you want
}
