Android文件存储小结

/*存储*/
FileOutputStream out=null;
PrintWriter pw=null;
try{
out=openFileOutput("data",Context.MODE_PRIVATE);
//可以看出openFileOutput方法返回的是FileOutputStream类型
pw=new PrintWriter(out);
pw.write(inputText);
pw.flush();
}catch(Exception e){
e.printStackTrace();
}finally{
try{
if(writer!=null){
writer.close();
}
}catch(IOException e){
e.printStackTrace();
}
}

/*读取*/
FileInputStream in=null;
BufferedReader br=null;
StringBuilder sb=new StringBuilder();
try{
in=openFileInput("data");
br=new BufferedReader(new InputSreamReader(in));
String temp="";
if((temp=br.readLine())!=null){
sb.append(temp);
}
}catch(IOException e){
e.printStackTrace();
}finally{
if(br!=null){
try{
br.close();
}catch(IOException e){
e.printStackTrace();
}
