安卓android sharepreference数据存储,保存输入框里面的数据

Fragment 里面 使用轻量级的数据存储sharepreference ,代码思路清晰。保存输入框里面的数据,实现按钮保存。

个人项目中简单清晰代码:

赵存档 编写 ,可以参考:

类继承Fragment实现点击事件:

 public View onCreateView(LayoutInflater inflater, ViewGroup container,
          Bundle savedInstanceState) {
          // TODO Auto-generated method stub
          View view = inflater.inflate(R.layout.wifi,container, false);
          view.findViewById(R.id.openwifi).setOnClickListener(this);
          view.findViewById(R.id.closewifi).setOnClickListener(this);
          wifiurl = (EditText)view.findViewById(R.id.editText1);
          wificom = (EditText)view.findViewById(R.id.editText2);
          wificamera = (EditText)view.findViewById(R.id.editText3);
      
     

sharedPreferences
= getActivity().getSharedPreferences("WifiSettings", Activity.MODE_PRIVATE); //私有数据; String str_wifiurl=sharedPreferences.getString("wifiurl", "192.168.8.1"); String str_wificom = sharedPreferences.getString("wificom", "2016"); String str_wificamera = sharedPreferences.getString("wificamera", "8083"); wifiurl.setText(str_wifiurl); wificom.setText(str_wificom); wificamera.setText(str_wificamera); return view; }

保存数据:

 

  public void savewifisettings(){
           
            sharedPreferences = getActivity().getSharedPreferences("WifiSettings", Activity.MODE_PRIVATE); //私有数据;  
            Editor editor = sharedPreferences.edit();//获取编辑器
            editor.putString("wifiurl",wifiurl.getText().toString());
            editor.putString("wificom",wificom.getText().toString());
            editor.putString("wificamera",wificamera.getText().toString());
            editor.commit();//提交修改
       } 


按钮保存:

 

    @Override
    public void onClick(View v) {
        // TODO Auto-generated method stub
         switch(v.getId()){
          
          case R.id.openwifi:
             
             savewifisettings();//开启wifi的时候保存一下设置
 
         }
    }
