setlistadapter with asynctask and sql

Question

我有一些代码，它与db一起工作。我尝试在asynctask中使用它，但是然后SetListadapter不起作用，并且无法显示我的list.How我能在asynctask中正确地执行它吗？

public void onCreate(Bundle savedInstanceState) {
    super.onCreate(savedInstanceState);


    new LoadViewTask().execute(); 
    final String[] from = {COLUMN_NAME, COLUMN_PHOTO};
    final int[] to = {R.id.name, R.id.photo};

    ScriptDBAdapter adapter = new ScriptDBAdapter(this, R.layout.list_item, mCursor, from, to);



    LayoutAnimationController controller = AnimationUtils
            .loadLayoutAnimation(this, R.anim.list_layout_controller);
    getListView().setLayoutAnimation(controller);


OnItemClickListener itemListener = new OnItemClickListener() {

        @Override
        public void onItemClick(AdapterView<?> parent, View v,
                int position, long id) {
            // TODO Auto-generated method stub

            String s =(String) ((TextView) v.findViewById(R.id.name)).getText();
            Intent intent = new Intent(MainActivity.this, SecondActivity.class);
             intent.putExtra("name_of_brend", s);
             startActivity(intent);
                                                          }
                        };

 getListView().setOnItemClickListener(itemListener);
    }  ///end OnOpen

 private void tryReleaseCursor() {
        if (mCursor != null) {
            stopManagingCursor(mCursor);
          //  mCursor.close();
            //mCursor = null;
        }
    }

 private class LoadViewTask extends AsyncTask<Void, Integer, Cursor>  
    {  
        //Before running code in separate thread  
        @Override  
        protected void onPreExecute()  
        {  
            //Create a new progress dialog  
            progressDialog = new ProgressDialog(MainActivity.this);  
            //Set the progress dialog to display a horizontal progress bar  
            progressDialog.setProgressStyle(ProgressDialog.STYLE_HORIZONTAL);  
            //Set the dialog title to 'Loading...'  
            progressDialog.setTitle("Loading...");  
            //Set the dialog message to 'Loading application View, please wait...'  
            progressDialog.setMessage("Loading application View, please wait...");  
            //This dialog can't be canceled by pressing the back key  
            progressDialog.setCancelable(false);  
            //This dialog isn't indeterminate  
            progressDialog.setIndeterminate(false);  
            //The maximum number of items is 100  
            progressDialog.setMax(100);  
            //Set the current progress to zero  
            progressDialog.setProgress(0);  
            //Display the progress dialog  
            progressDialog.show();  
        }  

        //The code to be executed in a background thread.  
        @Override  
        protected Cursor doInBackground(Void... params)  
        {  
             tryReleaseCursor();

             try {
                 SqliteScript script = new SqliteScript(getAssets().open("init2.sql"));
                 SqliteOpenHelper dbHelper = new SqliteOpenHelper(getApplicationContext(), script);
                 SQLiteDatabase database = dbHelper.getWritableDatabase();

                 mCursor = database.query(TABLE_BRANDS, null, null, null, "name", null, null);


                startManagingCursor(mCursor);





             } catch (IOException e) {
                 e.printStackTrace();
             }

            return mCursor;  
        }  

        //Update the progress  
        @Override  
        protected void onProgressUpdate(Integer... values)  
        {  

            progressDialog.setProgress(values[0]);  
        }  

        //after executing the code in the thread  
        protected void onPostExecute(Cursor mcCursor)  
        {  
            //close the progress dialog  
            progressDialog.dismiss();  
            //initialize the View  
           setListAdapter(adapter);
           adapter.notifyDataSetChanged();
            setContentView(R.layout.activity_main);  
        }  
    }  

我试图这样做，但没有任何作用。我无法理解如何填充适配器。请帮助我！
