Android开发 读取assets目录下的txt文件

/**
 * 读取assets下的txt文件，返回utf-8 String
 * @param context
 * @param fileName 不包括后缀
 * @return
 */
public static String readAssetsTxt(Context context,String fileName){
try {
//Return an AssetManager instance for your application's package
            InputStream is = context.getAssets().open(fileName+".txt");
int size = is.available();
// Read the entire asset into a local byte buffer.
byte[] buffer = new byte[size];
            is.read(buffer);
            is.close();
// Convert the buffer into a string.
            String text = new String(buffer, "utf-8");
// Finally stick the string into the text view.
return text;
        } catch (IOException e) {
// Should never happen!
// throw new RuntimeException(e);
            e.printStackTrace();
        }
return "读取错误，请检查文件名";
    }

直接上代码简单粗暴
