android 如何读取 assets、raws文件

1、读输入流的方法：通过读输入流返回一个String/***读输入流**@paramis*@return*/publicstaticStringgetStr足毂忍珩ingByInputStream(InputStreamis){Stringcontent=null;try{if(is!=null){byte[]buffer=newbyte[is.available()];ByteArrayOutputStreamarrayOutputStream=newByteArrayOutputStream();while(true){intreadLength=is.read(buffer);if(readLength==-1)break;arrayOutputStream.write(buffer,0,readLength);}is.close();arrayOutputStream.close();content=newString(arrayOutputStream.toByteArray());}}catch(FileNotFoundExceptione){e.printStackTrace();}catch(IOExceptione){e.printStackTrace();content=null;}finally{try{if(is!=null)is.close();}catch(IOExceptionioe){ioe.printStackTrace();}}returncontent;}

2、读assets文件的方法：publicstaticStr坡纠课柩ingreadAssets(Contextcontext,StringfileName){InputStreamis=null;try{is=context.getAssets().open(fileName);}catch(IOExceptione){e.printStackTrace();}returngetStringByInputStream(is);}

3、读raw文件的方法：publicstaticStringreadRaws(Contextcontext,intid){InputStreamis=context.getResources().openRawResource(id);returngetStringByInputStream(is);}
