【问题描述】：

我正在尝试释放我的声音池，但我不太清楚我在做什么。我是否正确释放了我的声音池对象？

我在这段代码中遇到错误，“”标记内的位： int sampleId = "(int) v.getTag();" - 为什么是这样？我该如何纠正？

我也正确地释放了我的声音池吗？

public class FragmentOne extends Fragment implements  View.OnClickListener ,  SoundPool.OnLoadCompleteListener 

SoundPool Clubb1;
Integer currentBtnId;

@Override
public View onCreateView(LayoutInflater inflater, ViewGroup container,
                         Bundle savedInstanceState
) 
    View rootView = inflater.inflate(R.layout.fragment_one_layout, container, false);
    Clubb1 = new SoundPool(10, AudioManager.STREAM_MUSIC, 1);

    Button buttonA = (Button) rootView.findViewById(R.id.buttonA);
    Button buttonB = (Button) rootView.findViewById(R.id.buttonB);
    Button buttonC = (Button) rootView.findViewById(R.id.buttonC);
    Button buttonD = (Button) rootView.findViewById(R.id.buttonD);
    Button buttonE = (Button) rootView.findViewById(R.id.buttonE);
    Button buttonF = (Button) rootView.findViewById(R.id.buttonF);
    Button buttonG = (Button) rootView.findViewById(R.id.buttonG);
    Button buttonH = (Button) rootView.findViewById(R.id.buttonH);
    Button buttonI = (Button) rootView.findViewById(R.id.buttonI);
    Button buttonJ = (Button) rootView.findViewById(R.id.buttonJ);

    buttonA.setTag(R.raw.clubb1);
    buttonB.setTag(R.raw.clubb2);
    buttonC.setTag(R.raw.clubb3);
    buttonD.setTag(R.raw.clubb4);
    buttonE.setTag(R.raw.clubb5);
    buttonF.setTag(R.raw.clubb6);
    buttonG.setTag(R.raw.clubb7);
    buttonH.setTag(R.raw.clubb8);
    buttonI.setTag(R.raw.clubb9);
    buttonJ.setTag(R.raw.clubb10);

    buttonA.setOnClickListener(this);
    buttonB.setOnClickListener(this);
    buttonC.setOnClickListener(this);
    buttonD.setOnClickListener(this);
    buttonE.setOnClickListener(this);
    buttonF.setOnClickListener(this);
    buttonG.setOnClickListener(this);
    buttonH.setOnClickListener(this);
    buttonI.setOnClickListener(this);
    buttonJ.setOnClickListener(this);

    Clubb1.setOnLoadCompleteListener(this);

    return rootView;


@Override
public void onClick(View v) 

    if(currentBtnId != null)
        Clubb1.release();
    

    currentBtnId = v.getId();
    int sampleId = (int) v.getTag();
    Clubb1.load(getActivity(), sampleId, 1);


@Override
public void onLoadComplete(SoundPool soundPool, int sampleId, int status) 
    switch (currentBtnId)
        case R.id.buttonA:
            soundPool.play(sampleId, 1, 1, 1, 0, 1);
            break;
        case R.id.buttonB:
            soundPool.play(sampleId, 1, 1, 1, 0, 1);
            break;
        case R.id.buttonC:
            soundPool.play(sampleId, 1, 1, 1, 0, 1);
            break;
        case R.id.buttonD:
            soundPool.play(sampleId, 1, 1, 1, 0, 1);
            break;
        case R.id.buttonE:
            soundPool.play(sampleId, 1, 1, 1, 0, 1);
            break;
        case R.id.buttonF:
            soundPool.play(sampleId, 1, 1, 1, 0, 1);
            break;
        case R.id.buttonG:
            soundPool.play(sampleId, 1, 1, 1, 0, 1);
            break;
        case R.id.buttonH:
            soundPool.play(sampleId, 1, 1, 1, 0, 1);
            break;
        case R.id.buttonI:
            soundPool.play(sampleId, 1, 1, 1, 0, 1);
            break;
        case R.id.buttonJ:
            soundPool.play(sampleId, 1, 1, 1, 0, 1);
            break;

    

【参考方案1】：

标签是一个对象。从 xml 中放置一个整数或从 java 中设置标签

buttonA.setTag(1);
buttonB.setTag(2);
buttonC.setTag(3);
buttonD.setTag(4);
buttonE.setTag(5);
buttonF.setTag(6);
buttonG.setTag(7);
buttonH.setTag(8);
buttonI.setTag(9);
buttonJ.setTag(10);

int id = (Integer) v.getTag ();

int sampleId = this.getResources().getIdentifier("clubb"+id, "raw", this.getPackageName());

Clubb1.load(getActivity(), sampleId, 1);

【讨论】：

如何将这段代码添加到我的项目中？我会放 int sampleId = (Integer)v.getTag();进入我的 xml？

你只想要原始资源 w.r.t 按钮点击右键？

我只需要我的 10 个按钮来播放与每个按钮对应的 10 个不同的声音片段，但我在 .java 代码的标记位上遇到了该错误。我需要在哪里将您编写的代码放入我的代码中？我不太擅长编程，所以请帮助我并解释要做什么以及把它们放在哪里。
