Android：如何將R.raw ...添加到作爲常規參數的方法中？

Question

我想創建一個方法，在不同的活動中播放一些聲音。

public void playSound(View view, ??? sound){ 
     mpSound = MediaPlayer.create(this, R.raw.sound); 
     mpSound.start(); 
    } 

什麼類型應該有「聲音」參數？

Answer 1

傳遞資源值可以integers這樣的：

public void playSound(View view, @RawRes int sound){ 
    mpSound = MediaPlayer.create(this, sound); 
    mpSound.start(); 
} 

調用你的方法是：

playSound(mView, R.raw.sound); 

Answer 2

它應該與@RawRes詮釋這樣一個整型：

public void playSound(View view, @RawRes int sound){ 
    mpSound = MediaPlayer.create(this, sound); 
    mpSound.start(); 
} 

你會看到這個錯誤如果您未通過原始資源：

Expected resource of type raw
