Question

如果我想在用户点击按钮时播放声音，则为：

Button one = (Button) this.findViewById(R.id.button1);
final MediaPlayer mp = MediaPlayer.create(this, R.raw.soho);     

one.setOnClickListener(new OnClickListener(){ 
    public void onClick(View v){ 
    mp.start(); }
    });

但是当我有2个声音并且我想在每次点击时播放不同的声音时我该怎么办？

Answer 1

int iClicked = 0;
public void onClick(View v) 
{ 
    iClicked++;
    if(iClicked % 2==0){
       // Do sth, e.g. play sound I
    }
    else { // Do sth else, e.g. play sound II
    }
}

Answer 2

试试这个

    private int rId=0;//class member
    //onclick
    final int [] music={R.raw.soho,R.raw.other};
    int id=music.length%2;
    final MediaPlayer mp = MediaPlayer.create(this, rId);
    id++;

Answer 3

我想在每次点击时播放不同的声音？

为此：

1。将所有原始文件ID存储在整数数组中。似乎：

int arrRawFiles ={R.raw.soho,R.raw.soho2,R.raw.soho3}

2. 在Button的onClick上根据数组长度生成一个随机整数，然后使用该数字从Array获取原始文件ID：

  public void onClick(View v) 
   { 
     int index = new Random().nextInt(arrRawFiles.length);
     MediaPlayer mp = MediaPlayer.create(this,index);
     mp.start(); 
   }

Answer 4

MediaPlayer mp;    
int clickCount=0;
one.setOnClickListener(new OnClickListener(){ 
public void onClick(View v) 
{ 
 if(clickCount %2 ==0){
    mp = MediaPlayer.create(this, R.raw.soho);
 }
 else{
    mp = MediaPlayer.create(this, R.raw.another);
 }
 mp.start();
 clickCount++;
} });

Answer 5

这很简单。查看示例代码并尝试...

        final boolean isFirstSound = true;
        Button one = (Button) this.findViewById(R.id.button1);
        final MediaPlayer mp = MediaPlayer.create(this, R.raw.soho);
        final MediaPlayer mp2 = MediaPlayer.create(this, R.raw.second_sound);
        one.setOnClickListener(new OnClickListener() {
            public void onClick(View v) {
                isFirstSound = !isFirstSound;
                if(isFirstSound)
                    mp.start();
                else
                    mp2.start();
            }
        });

您可以将音频片段的引用放入数组

int[] audio={R.raw.clip1,R.raw.clip2};
for(i=0;i<audio.length;i++){

//your MediaPlayer Code here

}

我没试过这个，但你会明白如何播放很多片段。祝你好运

Answer 7

public class ButtonPlayer implements View.OnClickListener {
    private final int[] sounds;
    private int soundIndex = -1;

    public ButtonPlayer(int... sounds) {
        this.sounds = sounds;
    }

    @Override
    public void onClick(View view) {
        if (sounds.length != 0) {
            soundIndex++;
            soundIndex = soundIndex % sounds.length;
            MediaPlayer mp = MediaPlayer.create(this, sounds[soundIndex]);
            mp.start();
        }
    }
}

然后在代码的某处：

Button one = (Button) this.findViewById(R.id.button1);
one.setOnClickListener(new ButtonPlayer(
                           R.raw.first_composition,
                           R.raw.second_composition));

您可以稍后通过为构造函数中的每个声音生成'n'个媒体播放器来优化此类。但这是优化的任务，而不是实施。

当然，总是尝试为小功能创建独立的类。不要搞乱活动。

Answer 8

    int count=0;
    Button one = (Button) this.findViewById(R.id.button1);
    final MediaPlayer mp = MediaPlayer.create(this, R.raw.soho);

    one.setOnClickListener(new View.OnClickListener(){
        public void onClick(View v)
        {
            count++;

            if(count%2==1) {
                //play first sound
            }else{
                //play second sound
            }

        } });

Answer 9

尝试类似

的内容

boolean playFirst = true;
 final MediaPlayer mp = MediaPlayer.create(this, R.raw.soho);
        final MediaPlayer mp2 = MediaPlayer.create(this, R.raw.second_sound_soho);
buttonClick.setOnClickListener(new OnClickListener() {
    public void onClick(View v) {
        if(playFirst == true){
             mp.start(); 
            playFirst = false;
        }else{
             mp2.start(); 
            playFirst = true;
        }

    }
});

Answer 10

如果您只想在2个声音之间切换，我认为您第一次检查时不需要布尔值或int值只需检查sound1是否正在播放 - ＆gt;停止sound1并打开sound2并反对

final MediaPlayer mp1 = MediaPlayer.create(this, R.raw.soho);
final MediaPlayer mp2 = MediaPlayer.create(this, R.raw.second_sound);

buttonClick.setOnClickListener(new OnClickListener() {
    public void onClick(View v) {
        if(mp1.isPlaying()){
             mp1.stop();
             mp2.start(); 
        }else{
             mp2.stop();
             mp1.start(); 
        }
    }
});
