Question

我需要制作一个从原始文件夹播放音频的应用程序。我为图像设置了OnClickListener，但它没有工作。

这是我的代码：

public class DetailInko extends Activity {
DBHelper dbHelper;
private TextView hangeul, romanisasi, artiIndo, keterangan;
String txAud;
private ImageView Audio;
Button bck;

public DetailInko() {
}

public void openDB() {
    dbHelper = new DBHelper(this);
    dbHelper.open();
}

@Override
protected void onCreate(Bundle savedInstanceState) {
    super.onCreate(savedInstanceState);
    setContentView(R.layout.detail_inko);
    hangeul = (TextView) findViewById(R.id.hangeul);
    romanisasi = (TextView) findViewById(R.id.romanisasi);
    artiIndo = (TextView) findViewById(R.id.artiIndonesia);
    keterangan = (TextView) findViewById(R.id.artiPlus);
    Audio = (ImageView) findViewById(R.id.buttonSound);
    bck = (Button) findViewById(R.id.back);

//来自之前活动的getdata，它已经运作良好

    Bundle b = new Bundle();
    b = this.getIntent().getExtras();
    if (b != null) {
        hangeul.setText(b.getString("Kor"));
        romanisasi.setText(b.getString("Rom"));
        artiIndo.setText(b.getString("Indo"));
        keterangan.setText(b.getString("Ket"));
        txAud = b.getString("Audio").replaceAll(".WAV", ""); // I'm not sure about this code
    }

    final MediaPlayer mp;
    int i;

//从原始文件夹中获取音频，但我不知道此代码是否可以从文件夹raw获取.wav文件。声音没有发挥

    i = getResources().getIdentifier(txAud, "raw", getPackageName());
    mp = MediaPlayer.create(DetailInko.this, i);

    onCLick = new OnClickListener() {

        @Override
        public void onClick(View v) {
            if(mp != null){
                mp.start();
            }

        }
    };
}

有人能解决这个问题吗？谢谢 -

试试这个：

just Put your file in res/raw folder and use

public void onClick（查看v）{

        if(mp.isPlaying())
        {
            mp.stop();
        } else{

        try {
            mp = MediaPlayer.create(this, R.raw.hello);
            mp.prepare();
            mp.start();
        } catch (IllegalStateException e) {
            e.printStackTrace();
        } catch (IOException e) {
            e.printStackTrace();
        }

}
