Can't get my checkedtextview to check or do anything for that matter. When I touch the listitem it doesn't do anything, it's not clickable. I've tried to add itemclicklistener to the listview but it didn't work. Am I missing something? or is it another way to do this?
MainActivity:
public class MainActivity extends AppCompatActivity {
DatabaseReference databaseItems;
TextView itemlist;
ListView listitem;
ImageView addlistitem;
List<Items> listitems;
{
}
@Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);
databaseItems = FirebaseDatabase.getInstance().getReference("Items");
itemlist = (TextView) findViewById(R.id.tvitemlist);
listitem = (ListView) findViewById(R.id.lvitemlist);
ArrayAdapter<Items> adapter = new ArrayAdapter<Items>(this, android.R.layout.simple_list_item_multiple_choice);
itemlist.setChoiceMode(ListView.CHOICE_MODE_MULTIPLE);
listitem.setAdapter(adapter);
listitem.setItemsCanFocus(false);
listitem.setOnItemClickListener(new AdapterView.OnItemClickListener() {
@Override
public void onItemClick(AdapterView<?> parent, View view, int position, long id) {
}
});
}
@Override
protected void onStart() {
super.onStart();
databaseItems.orderByChild("items").addValueEventListener(new ValueEventListener() {
@Override
public void onDataChange(DataSnapshot dataSnapshot) {
listitems.clear();
for (DataSnapshot itemsnapshot : dataSnapshot.getChildren()){
final Items items = itemsSnapshot.getValue(Items.class);
listitems.add(items);
final listItems adapter = new listItems(MainActivity.this, listitem);
listitem.setAdapter(adapter);
adapter.notifyDataSetChanged();
}
}
@Override
public void onCancelled(DatabaseError databaseError) {
}
});
}
Adapter:
public class listItems extends ArrayAdapter<Items> {
private Activity context;
private List<Items> listitems;
public listItems(Activity context, List<Items> listitems){
super (context, R.layout.list_items, listitems);
this.context = context;
this.listitems = listitems;
}
@NonNull
@Override
public View getView(final int position, @Nullable View convertView, @NonNull ViewGroup parent) {
LayoutInflater inflater = context.getLayoutInflater();
View listViewItem = inflater.inflate(R.layout.list_items, null, true);
final Items items = listitems.get(position);
final TextView tvitemname = (CheckedTextView) listViewItem.findViewById(R.id.tvitemname);
tvitemname.setText(item.getItemname());
((CheckedTextView) tvitemname).setChecked(listitems.get(position).setSelected(true));
tvitemname.setOnClickListener(new View.OnClickListener() {
@Override
public void onClick(View v) {
if(((CheckedTextView) tvjitemname).isChecked()) {
items.setSelected(false);
notifyDataSetChanged();
}else{
items.setSelected(true);
notifyDataSetChanged();
}
}
});
return listViewItem;
}
}
Model class:
public class Items {
String itemId;
String itemname;
private boolean IsSelected;
public Items(String itemId, String itemname, boolean isSelected) {
this.itemId = itemId;
this.itemname = itemname;
IsSelected = isSelected;
}
public String getItemId() {
return itemId;
}
public String getItemname() {
return itemname;
}
public boolean isSelected() {
return IsSelected;
}
public boolean setSelected(boolean selected) {
IsSelected = selected;
return false;
}
}
<?xml version="1.0" encoding="utf-8"?>
<CheckedTextView
xmlns:android="http://schemas.android.com/apk/res/android"
android:orientation="vertical"
android:layout_width="fill_parent"
android:layout_height="?android:attr/listPreferredItemHeight"
android:textAppearance="?android:attr/textAppearanceLarge"
android:gravity="center_vertical"
android:paddingLeft="6dip"
android:paddingRight="6dip"
android:checkMark="?android:attr/listChoiceIndicatorMultiple"
android:id="@+id/tvitemname"
android:checkMarkTint="@color/colorPrimary"/>
Unlike CheckBox
or any other CompoundButton
, you need to call setCheck
to toggle state on CheckedTextView
whenever it is clicked:
if (((CheckedTextView) tvjitemname).isChecked()) {
tvjitemname.setChecked(false);
items.setSelected(false);
notifyDataSetChanged();
} else {
tvjitemname.setChecked(true);
items.setSelected(true);
notifyDataSetChanged();
}
And also by the way, this line looks wrong:
// Wrong
((CheckedTextView) tvitemname).setChecked(listitems.get(position).setSelected(true));
It should be:
((CheckedTextView) tvitemname).setChecked(listitems.get(position).isSelected();
