团队冲刺04

  今天改了昨天的代码，用mode来区分添加和修改

  遇到的问题：我混乱了，不仅不能修改，连添加都不能了

  明天解决

@Override
    protected void onActivityResult(int requestCode, int resultCode, @Nullable Intent data) {

        int returnMode;  //-1不改变 0创建一个新笔记 1修改当前笔记
        long note_id;
        returnMode = data.getExtras().getInt("mode",-1);
        note_id = data.getExtras().getLong("id",0);
        //修改笔记
        if(returnMode == 1){
            String content = data.getStringExtra("content");
            String time = data.getStringExtra("time");
            int tag = data.getExtras().getInt("tag",1);
