Remove selected dynamic checked items from listview

Remove selected dynamic checked items from listview - android

Here, in a listview I have added a custom row in which Checkbox and EditText are there and with a add button I just add multiple views to my listview. Adding is working perfectly but when it comes to removing part the checked items are not removing and apart from that suppose I selected two items, then two items from last deleted. I don't know whats going on with my code please help me.
Here is my code:
MainActivity.java
public class MainActivity extends AppCompatActivity {
AdapterCustom customAdapter;
ArrayList<String> stringArrayList;
ListView listView;
ArrayList<Integer> listOfItemsToDelete;
AdapterCustom.ViewHolder item;
int POS;
#Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);
listOfItemsToDelete = new ArrayList<Integer>();
stringArrayList = new ArrayList<String>();
LinearLayoutManager layoutManager
= new LinearLayoutManager(this, LinearLayoutManager.VERTICAL, false);
listView = (ListView) findViewById(R.id.list_item);
customAdapter = new AdapterCustom(MainActivity.this, R.layout.main, stringArrayList);
}
public void addItems(View v) {
stringArrayList.add("");
listView.setAdapter(customAdapter);
customAdapter.notifyDataSetChanged();
}
public void removeItems(View v) {
if (listOfItemsToDelete.isEmpty()) {
Toast.makeText(getBaseContext(), "No items selected.",
Toast.LENGTH_SHORT).show();
} else {
Log.i("Delete Pos", POS + "");
if (!listOfItemsToDelete.equals("")) {
for (int j = 0; j < listOfItemsToDelete.size(); j++) {
stringArrayList.remove(listOfItemsToDelete.get(j) - j);
customAdapter.notifyDataSetChanged();
}
}
}
}
AdapterCustom.java
public class AdapterCustom extends ArrayAdapter<String> {
Context context;
ArrayList<String> stringArrayList;
ArrayList<Boolean> positionArray;
MainActivity activity;
public AdapterCustom(Context context, int resourceId, ArrayList<String> arrayList) {
super(context, resourceId, arrayList);
this.context = context;
this.stringArrayList = arrayList;
positionArray = new ArrayList<Boolean>(stringArrayList.size());
for (int i = 0; i < stringArrayList.size(); i++) {
positionArray.add(false);
}
activity = new MainActivity();
}
#Override
public int getCount() {
return stringArrayList.size();
}
#Override
public String getItem(int position) {
return stringArrayList.get(position);
}
#Override
public long getItemId(int position) {
return position;
}
public class ViewHolder {
EditText ediText;
CheckBox checkBox;
}
#Override
public View getView(final int position, View convertView, ViewGroup parent) {
if (convertView == null) {
item = new ViewHolder();
convertView = LayoutInflater.from(context).inflate(R.layout.main, null);
item.ediText = (EditText) convertView.findViewById(R.id.ediText);
item.checkBox = (CheckBox) convertView.findViewById(R.id.checkBox);
item.checkBox.setTag(new Integer(position));
convertView.setTag(item);
final View finalConvertView1 = convertView;
item.checkBox.setOnCheckedChangeListener(new CompoundButton.OnCheckedChangeListener() {
#Override
public void onCheckedChanged(CompoundButton compoundButton, boolean b) {
if (b) {
int getPosition = (Integer) compoundButton.getTag();
POS = getPosition;
listOfItemsToDelete.add(POS);
Log.i("position after check", POS + "");
Log.i("position check array", listOfItemsToDelete + "");
}
}
});
} else {
item = (ViewHolder) convertView.getTag();
}
item.checkBox.setTag(position);
return convertView;

You only remove the item from the array. Try removing the item also from the list view adapter with adapter.remove(itemPosition);

What does mean
- j
in this code:
for (int j = 0; j < listOfItemsToDelete.size(); j++) {
stringArrayList.remove(listOfItemsToDelete.get(j) - j);
customAdapter.notifyDataSetChanged();
}
?
I think that:
for (String itemToRemove:listOfItemsToDelete) {
stringArrayList.remove(itemToRemove);
}
customAdapter.notifyDataSetChanged();
listOfItemsToDelete.clear();
would be appropriate.

The best way to get this JSON inside ur app will be to use Volley :

Button click event with Custom List view

I have two button at bottom i.e after listview ends.
I am using a custom listview which display list items with alternate colors.
how to set setOnClickListener for both button at bottom?

((TextView) view.findViewById(R.id.duration)).setText(timeused.get(position));
return view;
//String.valueOf(value);
}
}

So these buttons are not part of your ListView? Well, than in your onCreate do something like:
solbtn = (Button)findViewById(R.id.solution);
solbth.setOnClickListener( toolbar.setOnClickListener(new View.OnClickListener() {
#Override
public void onClick(View v) {
yourMethod();
}
});
And the same goes for the second button.
Or you can make your Activity implement View.OnClickListener, after doing this you can set your click listeners like this:
//this two lines in your OnCreate
button1.setOnClickListener(this);
button2.setOnClickListener(this);
//somewhere later in the code
#Override
public void onClick(View v) {
//do something
}

Just add the clickListeners in your onCrete() method:
#Override
public void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
.....
solbtn = (Button) findViewById(R.id.home);
homebtn = (Button) findViewById(R.id.solution);
solbtn.setOnClickListener(new OnClickListener() {
public void onClick(View view) {
// do stuff for solution button
}
});
homebtn.setOnClickListener(new OnClickListener() {
public void onClick(View view) {
// do stuff for home button
}
});
.....
}

RadioButton btn=(RadioButton) view.findViewById(R.id.startfromrb);
String sfrom = btn.getText().toString();
arrayAdapter.setSelected((int)itemId);
Log.i("STARTFROM", sfrom);
}
});
//Add below function in adapter class
public void setSelected(int selectedPosition){
this.selectedPosition=selectedPosition;
notifyDataSetChanged();
}
Also remove from adapter
rbStartFrom.setOnClickListener(new OnClickListener() {
#Override
public void onClick(View v) {
selectedPosition = (Integer) v.getTag();
notifyDataSetInvalidated();
Log.i("IN ADAPTER", "" + selectedPosition);
}
});
And add android:clickable="false" and set selectedPosition to -1 by default

The first I see is, that You have to change the reference to the Views where You want to set the other views below :
<Spinner
android:id="#+id/spinner1"
android:layout_width="match_parent"
android:layout_height="wrap_content" />
<ListView
android:id="#+id/lstDemo"
android:layout_width="fill_parent"
android:layout_height="match_parent"
android:layout_below="#+id/spinner1" <!-- correct: #id/spinner1 -->
android:layout_marginBottom="60dp" >
</ListView>
<TextView
android:id="#+id/emptytv"
android:layout_width="match_parent"
android:layout_height="match_parent"
android:layout_below="#+id/spinner1" <!-- correct: #id/spinner1 -->
android:layout_marginBottom="60dp"
android:gravity="center_vertical|center_horizontal"
android:text="No Records Found."
android:textSize="25sp" />
<Button
android:id="#+id/button1"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:layout_alignParentBottom="true"
android:layout_alignParentLeft="true"
android:layout_marginLeft="31dp"
android:text="Button" />
</RelativeLayout>
But anyway, Your TextView is sitten directly above the listView, is this Your intention? If not, You have to set
android:layout_below="#+id/lstDemo"
Also, if You get any errors, please post the logcat output. If You just have problems with Your layout, please explain clear enough what exactly You want.
EDIT
try to get the selected item String like this:
final String item = (String) parent.getItemAtPosition(position);
loadListView(item);

Unable to select an item in a ListView whose content is set by an Array Adapter

I couldn't select an item on ListView. I use Custom Adapter to set content of ListView. I have set OnItemClickListener of ListView. However, it didn't respond. I appriciate your help. Here is my code:

It is related to checkbox item in connections.xml which is the list row item. If I remove checkbox, related listeners responses. I think, it may be thought there is no need a setItemOnClickListener(..) method since each row has a checkbox. Or it is a bug.

CheckedTextView doesnt Toggle

I have a custom listview that has CheckedTextView. When i click the the items it doesn't toggle the checked state of the object and reflect in the ui.

Could you just use android.R.layout.simple_list_item_multiple_choice instead of dialog_list_item_category.xml?
Update: #Luksprog's comment is the solution: Remove the RelativeLayout and it works just like with android.R.layout.simple_list_item_multiple_choice.

Are You using the proper xml?
There's
dialog_list_item_categories.xml
but in your code You use everywhere
R.layout.dialog_list_item_category

Remove selected dynamic checked items from listview - android

You only remove the item from the array. Try removing the item also from the list view adapter with adapter.remove(itemPosition);
