如何根据在Edittext中输入的文字查找并播放音频文件

Question

当我输入动物名称并播放动物声音时，我制作的以下代码工作正常，但我如何才能使 200 个声音文件更简单。比如从 edittext 中获取字符串并从原始文件夹中搜索文件并播放。如果输入的文本是 "dog" 它应该播放 "dog.mp3"

    editText.addTextChangedListener(new TextWatcher() {
                public void afterTextChanged(Editable s) {
                    {
                        String name      =  editText.getText().toString();
                        if(name.contentEquals("cow")){

                            mp = MediaPlayer.create(Selection1Page1.this, R.raw.cow);
                            mp.start();
                        }
                        if(name.contentEquals("bat")){

                            mp = MediaPlayer.create(Selection1Page1.this, R.raw.bat);
                            mp.start();
                        }
                        if(name.contentEquals("cat")){

                            mp = MediaPlayer.create(Selection1Page1.this, R.raw.cat);
                            mp.start();
                        }
                    }

                }

应用给定的解决方案 here。在某处添加实用方法：

public static int getResourceIdentifierForRawFile(Context context, String fileName) {
    final String packageName = context.getPackageName();
    final Resources resources = context.getResources();
    return resources.getIdentifier(fileName, "raw", packageName);
}

并用它将文件名转换成id值：

final String fileName = editText.getText().toString();
final int fileResId = getResourceIdentifierForRawFile(this, fileName); 
//"this" assumes you are inside a class that inherits from Context, i.e. an Activity
MediaPlayer.create(this, fileResId).start();
