ListView使用CursorAdapter增加和删除item

     @Override
     protected void onCreate(Bundle savedInstanceState) {
         // TODO 自动生成的方法存根
         super.onCreate(savedInstanceState);
         requestWindowFeature(Window.FEATURE_NO_TITLE);
         setContentView(R.layout.resume);

         myDataBaseHelper = new MyDataBaseHelper(this, "Resume1.db", null, 1);
         db = myDataBaseHelper.getReadableDatabase();

         ViewUtils.inject(this);

         cursor = db.query("Resume", null, null, null, null, null, null);
         adapter = new DataCursorAdapter(this, cursor);
         ListView listView=(ListView) findViewById(R.id.list_view);
         listView.setAdapter(adapter);
     }

     @Override
     protected void onResume() {
         // TODO 自动生成的方法存根
         super.onResume();
         cursor = db.query("Resume", null, null, null, null, null, null);
         adapter.changeCursor(cursor);
     }

DataCursorAdapter部分代码：

     @Override
     public View newView(Context context, Cursor cursor, ViewGroup parent) {
         // TODO 自动生成的方法存根
         ViewHolder viewHolder=new ViewHolder();
         LayoutInflater inflater=(LayoutInflater) context.getSystemService(Context.LAYOUT_INFLATER_SERVICE);
         View view=inflater.inflate(R.layout.resume_item, parent,false);
         viewHolder.nameListET=(TextView) view.findViewById(R.id.nameListET);
         viewHolder.relationListSpinner=(TextView) view.findViewById(R.id.relationListSpinner);
         viewHolder.schoolListET=(EditText) view.findViewById(R.id.schoolListET);
         viewHolder.workListET=(EditText) view.findViewById(R.id.workListET);
         viewHolder.deleteResume=(Button) view.findViewById(R.id.deleteResume);
         view.setTag(viewHolder);
         return view;
     }

     @Override
     public void bindView(View view, final Context context, final Cursor cursor) {
         // TODO 自动生成的方法存根

         viewHolder = (ViewHolder) view.getTag();
         name = cursor.getString(cursor.getColumnIndex("name"));
         relation = cursor.getString(cursor.getColumnIndex("relation"));
         school = cursor.getString(cursor.getColumnIndex("school"));
         work = cursor.getString(cursor.getColumnIndex("work"));
         final String itemId = cursor.getString(cursor.getColumnIndex("_id"));

         viewHolder.nameListET.setText(name);
         viewHolder.relationListSpinner.setText(relation);
         viewHolder.schoolListET.setText(school);
         viewHolder.workListET.setText(work);
         viewHolder.deleteResume.setTag(itemId);

         viewHolder.deleteResume.setOnClickListener(new OnClickListener() {

             @Override
             public void onClick(View v) {
                 // TODO 自动生成的方法存根
                 myDataBaseHelper = new MyDataBaseHelper(context, "Resume1.db", null, 1);
                 db = myDataBaseHelper.getReadableDatabase();
                 db.delete("Resume", "_id= "+v.getTag(), null);
                 cursor.requery();
                 notifyDataSetChanged();

             }
         });

     }

     @Override
     public void changeCursor(Cursor cursor) {
         // TODO 自动生成的方法存根
         super.changeCursor(cursor);
     }

     class ViewHolder{

         TextView nameListET;
         TextView relationListSpinner;
         EditText schoolListET;
         EditText workListET;
         Button deleteResume;

     }
