Android如何在長按按鈕上設置聲音作爲鈴聲

Question

如何將聲音設置爲長按按鈕上的鈴聲？

在它僅適用於sound4但不sound5

Answer 1

這是因爲你保存到文件的設置靜態每次都保存R.raw.sound4（你寫savering（R.raw.sound4））。您需要使用您傳遞給它的變量（ressound）並使用它來決定保存哪個文件。

要做到這一點，最好的辦法可能是創造聲音的陣列（或它們的引用）像這樣（這正好在你的java文件開始與可變減速的其餘部分）：

int[] soundArray = {R.raw.sound1,R.raw.sound2,R.raw.sound3}; // etc... 

哪你會添加到SoundManager類像這樣（這正好你在哪裏手動添加的聲音）

for (int i=0; i<soundArray.length; i++){ // Loops over the sound array 
    mSoundManager.addSound(i, soundArray[i]); // Adds sounds to sound manager 
    } 

然後你savering功能將使用傳遞的參數知道哪些文件進行保存。 （這正好在那裏你以前稱爲函數）

savering(soundArray[ressound]);
