i am trying to parse that arraylist value but it’s not working see the below code.
sdcardImages.setOnItemClickListener(new OnItemClickListener() {
public void onItemClick(AdapterView parent, View v, int position, long id) {
Intent intent = new Intent(ParxmlActivity.this, tabview.class);
intent.putStringArrayListExtra("numbers", mspec_List);
//intent.putExtra("name",model_List.get(position).name);
startActivity(intent);

If you are having String ArrayList you can simply pass it using
intent.putStringArrayListExtra(name, value). For more you can check my answerhere.
