java - Android Java音板代码仅将第一个按钮设置为铃声/等

Question

我一直在玩弄这段代码，显然我正在尝试制作一个音板，可以在长按等情况下保存铃声。

不过，这是一个按钮的基本代码。我一直在互相复制相同的代码，试图制作数组，只是一切......我无法让这段代码按照我想要的方式工作。

当它们是多个按钮和更多代码时。

我可以让所有按钮都播放声音。我可以让菜单弹出每个按钮。不过，第一个按钮始终是被保存的那个，其余的只是从 map 上掉下来。

我假设我在以下代码中的数据流没有被切断并被其他声音按钮拾取。无论哪种方式，它都不起作用。请帮助我。

public class Soundboard extends Activity {
    private SoundManager mSoundManager;

    /** Called when the activity is first created. */
    @Override
    public void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.main);

        mSoundManager = new SoundManager();
        mSoundManager.initSounds(getBaseContext());
        mSoundManager.addSound(1, R.raw.sound1);

        Button SB = (Button)findViewById(R.id.sound1);

        SB.setOnClickListener(new OnClickListener() {
            public void onClick(View v) {
               mSoundManager.playSound(1);                      
            }
        });

        Button btn = (Button) findViewById(R.id.sound1);
        registerForContextMenu(btn);
    }

    @Override
    public void onCreateContextMenu(ContextMenu menu, View v,ContextMenuInfo menuInfo) {
        super.onCreateContextMenu(menu, v, menuInfo);
        menu.setHeaderTitle("Save as...");
        menu.add(0, v.getId(), 0, "Ringtone");
        menu.add(0, v.getId(), 0, "Notification");
    }

    @Override   
    public boolean onContextItemSelected(MenuItem item) { 
        if(item.getTitle()=="Ringtone"){function1(item.getItemId());}

Answer 1

我只是自己学习 Android 编程，但似乎这就是为什么你总是保存第一个声音:

savering(R.raw.sound1)

和

savenot(R.raw.sound1)

这两个都明确保存了第一个声音。除非您为每个按钮编写了单独的 function1 和 function2。但必须有比这更好的方式来管理储蓄。
