Adapter class:
holder.chb.setOnCheckedChangeListener(new OnCheckedChangeListener() {
@Override
public void onCheckedChanged(CompoundButton buttonView, boolean isChecked) {
// TODO Auto-generated method stub
if(!holder.chb.isChecked()) {
if (!GridImageActivity.selectedFile.contains((String) list.get(position))) {
GridImageActivity.selectedFile.add((String) list.get(position));
// you use the ID field to hold the position
}} else {
GridImageActivity.selectedFile.remove((String) list .get(position));
}
}
});
Activity Calss:
delmemory.setOnClickListener(new OnClickListener() {
@Override
public void onClick(View v) {
// TODO Auto-generated method stub
Iterator iterator = selectedFile.iterator();
//Log.i("1", "" + iterator.next());
while (iterator.hasNext()) {
new File(iterator.next().toString()).getAbsoluteFile().delete();
gridview.setAdapter(new ImageAdapter(GridImageActivity.this, DashboardActivity.imagelist,str));
}
}
});
