java - 使保存到 SD 卡和上下文菜单功能动态，或相对于按下的按钮

Question

相对于下面的代码，我该如何制作

if (savering(R.raw.sound1)){

和

String filename=”sound1″+”.ogg”;

和

values.put(MediaStore.MediaColumns.TITLE, “sound1″);

动态而不是静态，以便将保存的声音文件基于按下的按钮？

我的声音文件在一个 soundArray 中，保存为 sound1、sound2、sound3 等。每个声音文件都有一个按钮。点击播放，长按弹出下方上下文菜单。

如有任何帮助或提示，我们将不胜感激。

Answer 1

我认为您可以通过以下更改获得解决方案:

1:取两个数组。一个用于存储您要添加到菜单中以播放的铃声按钮 ID，另一个数组分别具有该按钮声音的相应声音数组 ID；

例如，

int btnid=new int[count];//count is no of buttons for playing ring
int rawid=ne int[count];

然后你可以捕获点击的菜单项的按钮的 ID，你必须在 function1 中与你的 btnid 数组进行比较，并获得匹配的 btnid 数组的索引。

2: 使用相同的索引后，您可以在 rawid 数组中找到 rawsource。

您的第一个问题已解决，现在对于文件名的第二个问题，您只需尝试以下操作:

String filename="sound"+id+".ogg";//id is index of array
