java - 异常调度输入事件

Question

我正在尝试做列表视图。我的应用程序在第一次打开时工作，但在返回主菜单后它不再工作并且在模拟器上给出错误“不幸的是应用程序已停止”。

这是我的主要内容。

public class ListMyJob extends Activity {
        ItemListBaseAdapter adapter;               //////after answers ı added.
        public void onBackPressed() {             //////after answers ı added.
                                                 //////after answers ı added.
            adapter.notifyDataSetChanged();      //////after answers ı added.

    }                                           //////after answers ı added.
    ArrayList<ItemDetails> jobs = new ArrayList<ItemDetails>();{   /////////////some list data /////////////////////}

    @Override
    public void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.main);
        ArrayList<ItemDetails> image_details = jobs;

        final ListView lv1 = (ListView) findViewById(R.id.listV_main);
        lv1.setAdapter(new ItemListBaseAdapter(this, image_details));
        lv1.setOnItemClickListener(new OnItemClickListener() {
            @Override
            public void onItemClick(AdapterView<?> a, View v, int position, long id) { 
                Object o = lv1.getItemAtPosition(position);
                ItemDetails obj_itemDetails = (ItemDetails)o;
                Toast.makeText(ListMyJob.this, "You have chosen : " + " " + obj_itemDetails.getName(), Toast.LENGTH_LONG).show();
                Intent intObj = new Intent(ListMyJob.this,ListMyExercises.class);  /////modified

                intObj.putExtra("description",obj_itemDetails.getItemDescription());
                intObj.putExtra("name",obj_itemDetails.getName());
                intObj.putExtra("imagenumber",obj_itemDetails.getImageNumber());
                intObj.putExtra("videonumber", obj_itemDetails.getVideoNumber());

                ItemDetailsWrapper wrapper = new ItemDetailsWrapper(obj_itemDetails.getChild());
                intObj.putExtra("exerciselist", wrapper); // i.putExtra("obj", new ItemDetailsWrapper(list));

                startActivity(intObj);
            }  
        });
    }
}

我在 logcat 上收到这些错误。
