这是2个功能。一种是从RAW读取的，另一种是从资产读取的
public static void readRaw(Context ctx,int res_id) { InputStream is = ctx.getResources().openRawResource(res_id); InputStreamReader isr = new InputStreamReader(is); BufferedReader br = new BufferedReader(isr, 8192); // 2nd arg is buffer // size // More efficient (less readable) implementation of above is the // composite expression try { String test; while (true) { test = br.readLine(); // readLine() returns null if no more lines in the file if (test == null) break; } isr.close(); is.close(); br.close(); } catch (IOException e) { e.printStackTrace(); }}并从资产文件夹
public static String getQuestions(Context ctx,String file_name) { AssetManager assetManager = ctx.getAssets(); ByteArrayOutputStream outputStream = null; InputStream inputStream = null; try { inputStream = assetManager.open(file_name); outputStream = new ByteArrayOutputStream(); byte buf[] = new byte[1024]; int len; try { while ((len = inputStream.read(buf)) != -1) { outputStream.write(buf, 0, len); } outputStream.close(); inputStream.close(); } catch (IOException e) { } } catch (IOException e) { } return outputStream.toString();}
