The problem I am facing is that I am unable to store the checked value of my checkbox
Here is my code:
final Button markpresent = (Button) findViewById(R.id.Button01);
markpresent.setOnClickListener(new View.OnClickListener() {
public void onClick(View v)
{
// Perform action on click
Toast.makeText(display.this,"You have selected to mark the present students",Toast.LENGTH_SHORT).show();
SparseBooleanArray checked = lView.getCheckedItemPositions();
ArrayList<String> items = new ArrayList<String>();
for (int i = 0; i < arr2.length; i++)
{
if (checked.get(i))
{
items.add(arr2[i]);
System.out.println(items);
}
}
Log.d("", "items:");
for (String string : items)
{
Log.d("", string);
System.out.println(items);
}
}
});
Only when the button is pressed , I want the values checked by the user to be stored in a String. However, my code isn’t working fine.
Here is logcat:

store the value in sharedPreferences and when you need again just retrieve from sharedPreferences and do your task.
