如何读出assets的资源

public class Utils {

    public static List<Message> getMesages() {

//File file = new File("file:///android_asset/helloworld.txtv");

AssetManager assetManager = getAssets();
InputStream ims assetManager.open("helloworld.txt");

     }
}

想读出assets文件夹下的资源。当使用File时显示fileNotFound异常，但是使用AssetManager getAssets()方法时，又不能识别。请问有什么方法可以解决这个问题呢？

public void getGetAssets(){
AssetManager assetManager= context.getAssets();
Log.e(TAG, assetManager.getLocales()+"");
try {
InputStream inputStream =   assetManager.open("atest");
inputStream.read();
InputStreamReader isr = new InputStreamReader(inputStream);  
BufferedReader br = new BufferedReader(isr);  
Log.i(TAG,"inputStream :" + inputStream.read());
Log.i(TAG,"BufferedReader :" +br);
Log.i(TAG,"BufferedReader :" +br.toString());
Log.i(TAG,"BufferedReader :" +new String(br.readLine()));
} catch (IOException e) {
    // TODO Auto-generated catch block
    e.printStackTrace();
}
}

你只要保证你的assets文件下有这个“atest”文件就可以了，我试了不会报错的。我的测试文件内容就是aaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaa

    StringBuilder ReturnString = new StringBuilder();
    InputStream fIn = null;
    InputStreamReader isr = null;
    BufferedReader input = null;
    try {
        fIn = context.getResources().getAssets()
                .open(fileName, context.MODE_WORLD_READABLE);
        isr = new InputStreamReader(fIn);
        input = new BufferedReader(isr);
        String line = "";
        while ((line = input.readLine()) != null) {
            ReturnString.append(line);
        }
    } catch (Exception e) {
        e.getMessage();
    } finally {
        try {
            if (isr != null)
                isr.close();
            if (fIn != null)
                fIn.close();
            if (input != null)
                input.close();
        } catch (Exception e2) {
            e2.getMessage();
        }
    }
    return ReturnString.toString();
}

getAssets() 只能在 Activity 里用
