Android Question
Android lost of check state after scrolling
Whenever scrolling up and down, I lose check state of checkbox.
I can't solve this problem for two days......
Please help me
Here is my code.
public View getView(final int position, View view, ViewGroup parent) {
context = parent.getContext();
inflater = (LayoutInflater) context.getSystemService(Context.LAYOUT_INFLATER_SERVICE);
if (view == null) {
holder = new ViewHolder();
view = inflater.inflate(R.layout.custom_llistview, parent, false);
holder.img_view = (ImageView) view.findViewById(R.id.custom_imageView);
holder.txt_view = (TextView) view.findViewById(R.id.custom_textView);
holder.checkbox = (CheckBox) view.findViewById(R.id.check_box);
view.setTag(holder);
}
else {
holder = (ViewHolder)view.getTag();
}
holder.checkbox.setChecked(check_flag_arr[position]);
holder.checkbox.setOnCheckedChangeListener(new CompoundButton.OnCheckedChangeListener() {
@Override
public void onCheckedChanged(CompoundButton buttonView, boolean isChecked) {
if (isChecked) {
check_flag_arr[position] = isChecked;
else {
check_flag_arr[position] = isChecked;
}
}
});
file_path = list_item.get(position).getFile_path();
Bitmap showImage = BitmapFactory.decodeFile(file_path);
holder.img_view.setImageBitmap(showImage);
list_contents = file_path.substring(45, 65);
holder.txt_view.setText(list_contents);
return view;
}
And detail explanation will be a great pleasure to me.
I must solve this problem.

whenever you scroll setOnCheckedChangeListener is called
Removing setOnCheckedChangeListener and implimant setOnClickListener
holder.checkbox.setOnClickListener(new View.OnClickListener() {
@Override
public void onClick(View v) {
if (holder.checkbox.isChecked()) {
check_flag_arr[position] = true;
} else {
check_flag_arr[position] = false;
}
}
});
