Question

我试图释放我的声音池，但我不太清楚我在做什么。我是否正确发布了声音池对象？

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

我是否也正确发布了声音池？

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);

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

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

@Override

    switch (currentBtnId){
        case R.id.buttonA:
            soundPool.play(sampleId, 1, 1, 1, 0, 1);
            break;
        case R.id.buttonB:

    }

Answer 1

标签是一个对象。从xml放置一个Integer或从java

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（＆＃34; clubb＆＃34; + id，＆＃34; raw＆＃34;，this.getPackageName（））;

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