进度对话框UI冻结/慢速

Question

我有一个进度对话框,我在程序中使用了一个部分,我在后台进行了时间密集型操作,但是当对话框显示时,UI或微调器图标冻结/慢/犹豫使程序看起来好像冻结了一样.在我onPostExecute的我AsyncTask解雇对话.

为什么会发生这种情况,因为我在后台完成所有工作？

这是我的代码

pDialog = ProgressDialog.show(FullGame.this,"Starting New Game","Please Wait...", true);
new StartNewGame().execute(); 

    private class StartNewGame extends AsyncTask<Void,Void,Boolean>{

    @Override
    protected Boolean doInBackground(Void... params) {
        try{
            ContentValues values = new ContentValues();
            Cursor c = getContentResolver().query(Games.PART1_URI,new String[] {Games.PART1_NUM},
                    Games.PART1_GAME_ID+"="+gameID+" AND "+Games.PART1_FRAME_NUM+"="+10,null,null);
            c.moveToFirst();
            String num = c.getString(0);
            int part1 =0;
            if(num.equals("-")){
                part1=0;
            }else{
                part1=Integer.parseInt(num);
            }

            c = getContentResolver().query(Games.PART2_URI,new String[] {Games.PART2_NUM},
                    Games.PART2_GAME_ID+"="+gameID+" AND "+Games.PART2_FRAME_NUM+"="+10,null,null);
            c.moveToFirst();
            int part2 = 0;
            if(num.equals("-")){
                part2=0;
            }else{
                part2=Integer.parseInt(num);
            }

            c = getContentResolver().query(Games.PART3_URI,new String[] {Games.PART3_NUM},
                    Games.PART3_GAME_ID+"="+gameID,null,null);
            c.moveToFirst();
            int part3 = 0;

更新: 昨晚在调试模式下运行代码似乎开始在for循环中执行它但仍然所有这些都在一个单独的线程中完成,我只是将值插入到我的数据库中

更新2 如果我注释掉for循环,进度对话框会显示不到一秒钟,所以即使我AsyncTask在插件中执行所有操作仍必须在UI线程中运行

Answer 1

弄清楚了，我在 UI 线程上有一个我没有注意到的失控方法
