团队冲刺二（2）

朴远东：学习线程，尝试解决文本文件获取板块的显示问题。尝试了多个方法未能成功，在编写上出现了一些调用错误，正在排查。

张宏伟：换了下拉框模式，放弃了implements接口，重写了方法

            btn_advice_submit=findViewById(R.id.advice_submit);
            mProSpinner=(Spinner) findViewById(R.id.spinner_advice);
            init();
        }
        private void init()
        {
            mProSpinner=(Spinner)findViewById(R.id.spinner_advice);
            mStringArray=getResources().getStringArray(R.array.advice_name);
            mProAdapter=new ArrayAdapter<String>(this,android.R.layout.simple_spinner_item,mStringArray);
            mProSpinner.setPrompt("选择你需要的服务类型");
            mProAdapter.setDropDownViewResource(android.R.layout.simple_spinner_dropdown_item);
            mProSpinner.setAdapter(mProAdapter);
            mProSpinner.setOnItemSelectedListener(new OnItemSelectedListener() {
                @Override
                public void onItemSelected(AdapterView<?> parent, View view, int position, long id) {
                }
                @Override
                public void onNothingSelected(AdapterView<?> parent) {
                }
            });
        }

}

王兵兵：学习了ButterKnife框架，减少了代码的重复量，避免了重复使用findViewByid来寻找VIEW的id加快了运行速度，是界面更加简洁
