android - 保存 android 特定的按钮声音

Question

我有一个音板，我正在尝试将声音保存为铃声或通知，但它每次都保存相同的声音，我认为这是从“这里有人可以阐明一些问题吗？认为它需要改变 R。 raw.sound1 因此它会提取单击哪个按钮以调出上下文菜单的声音。

我已经添加了循环和集成代码，使按钮能够以防万一。

编辑完整代码 - 错误:无法解析 selectedSoundId
:- 对于表示 selectedSoundId 的每三位代码

不确定我是否已经完成了这一点: 我在哪里以及如何添加它？

“int selectedSoundId”应该声明为类字段，以使其在每个类方法中都可访问。

public class Soundboard extends Activity {
 private SoundManager mSoundManager;

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

    final MediaPlayer player = new MediaPlayer();
    final Resources res = getResources();

    //just keep them in the same order, e.g. button01 is tied to backtoyou
    final int[] buttonIds = { R.id.backdoors etc};
    final int[] soundIds = { R.raw.back_doors etc };

    View.OnClickListener listener = new View.OnClickListener() {
        public void onClick(View v) {
            //find the index that matches the button's ID, and then reset
            //the MediaPlayer instance, set the data source to the corresponding
            //sound effect, prepare it, and start it playing.
            for(int i = 0; i < buttonIds.length; i++) {
                if(v.getId() == buttonIds[i]) {
                    selectedSoundId = soundIds[i];
                    AssetFileDescriptor afd = res.openRawResourceFd(soundIds[i]);
                    player.reset();
                    try {
                        player.setDataSource(afd.getFileDescriptor(), afd.getStartOffset(), afd.getLength());
                    } catch (IllegalArgumentException e) {
                        // TODO Auto-generated catch block
                        e.printStackTrace();
                    } catch (IllegalStateException e) {
                        // TODO Auto-generated catch block

                    player.start();
                    break;
                }
            }
        }
    };

    //set the same listener for every button ID, no need
    //to keep a reference to every button
    for(int i = 0; i < buttonIds.length; i++) {
        Button soundButton = (Button)findViewById(buttonIds[i]);
        registerForContextMenu(soundButton);

Answer 1

我没看到你在哪里替换

的内容

R.raw.sound1

您将其作为参数传递，因此，正如我在您的代码中观察到的那样，您每次调用保存方法时都会保存相同的声音。

编辑:

1. 创建一个 int 变量来保存关于最后选择的声音的信息:

   int selectedSoundId;

2. 在 onClickListener 中将 selectedSoundId 设置为与当前按钮关联的声音 ID:

   if(v.getId() == buttonIds[i]) { selectedSoundId = soundIds[i]; //剩下的代码

3. 将 selectedSoundId 传递给 savering 和 savenot 方法:

   保存(selectedSoundId)； savenot(selectedSoundId);

希望这对您有所帮助。

编辑 2:我正在粘贴您的代码和我的更正。

广告 2。这是您需要保存有关当前声音 ID 的信息的部分。

final int[] buttonIds = { R.raw.sound1 "etc all buttons here"};
    final int[] soundIds = {R.raw.sound1 "etc all sounds here"};

    View.OnClickListener listener = new View.OnClickListener() {
        public void onClick(View v) {
            //find the index that matches the button's ID, and then reset
            //the MediaPlayer instance, set the data source to the corresponding
            //sound effect, prepare it, and start it playing.
            for(int i = 0; i < buttonIds.length; i++) {
                if(v.getId() == buttonIds[i]) {
                    selectedSoundId = soundIds[i];
                    AssetFileDescriptor afd = res.openRawResourceFd(soundIds[i]);
                    player.reset();
                    try {
                        player.setDataSource(afd.getFileDescriptor(), afd.getStartOffset(), afd.getLength());
                    } catch (IllegalArgumentException e) {
                        // TODO Auto-generated catch block
                        e.printStackTrace();
                    } catch (IllegalStateException e) {
                        // TODO Auto-generated catch block
                        e.printStackTrace();
                    } catch (IOException e) {
                        // TODO Auto-generated catch block
                        e.printStackTrace();
                    }
                    try {
                        player.prepare();
                    } catch (IllegalStateException e) {
                        // TODO Auto-generated catch block
                        e.printStackTrace();
                    } catch (IOException e) {
                        // TODO Auto-generated catch block
                        e.printStackTrace();
                    }
                    player.start();
                    break;
                }
            }
        }
    };

广告 3。这是调用savering和savenot方法的部分。

if 
 (savering(selectedSoundId)){   
  // Code if successful   
  Toast.makeText(this, "Saved as Ringtone", Toast.LENGTH_SHORT).show(); 
 }           
 else           
 { 
  // Code if unsuccessful   
  Toast.makeText(this, "Failed - Check your SDCard", Toast.LENGTH_SHORT).show();
 }

}
public void function2(int id){   
 if 
 (savenot(selectedSoundId)){   
  // Code if successful   
  Toast.makeText(this, "Saved as Notification", Toast.LENGTH_SHORT).show(); 
 }           
 else           
 { 
  // Code if unsuccessful   
  Toast.makeText(this, "Failed - Check your SDCard", Toast.LENGTH_SHORT).show(); 
 }
}
