Question

你能否告诉我为什么会收到这个错误？我做错了什么？

int[] songPos = {R.raw.position1,R.raw.position2,R.raw.position3,R.raw.position4};
    UnitPackage=getApplicationContext().getPackageName();

    list.setOnItemClickListener(new OnItemClickListener() {

               @Override
               public void onItemClick(AdapterView<?> parent, View view, int position, long id) {
                   int resId = getResources().getIdentifier("raw/"+songPos[position], null, UnitPackage);
                   MediaPlayer mp = MediaPlayer.create(CentralActivity.this, resId);  

                   if (mp.isPlaying()) {
                        mp.pause();
                    } else {
                        mp.start();
                    }
               }
               });

我在这里做错了什么？我错过了什么或？我是否需要为此找到另一种方法或者它可以解决？

Answer 1

更改

int resId = getResources().getIdentifier("raw/"+songPos[position], null, UnitPackage);

到

int resId = songPos[position];

您已将所有id存储在songPos中。无需使用getIdentifier

再次检索它
