Android读写配置2

上篇文章采用 Properties 读写配置,各种路径错误,要么没有写入权限.

后来查资料,采用另一种方式读写 SharedPreferencesImpl

直接贴代码

公共类 -- 读写

package com.**.demo.utils;

import android.content.Context;
import android.content.SharedPreferences;
import android.util.Log;

public class UrlConfig {
    private static SharedPreferences share;
    private static String configPath = "appConfig";

    public static SharedPreferences getProperties(Context context) {
        try {
            share = context.getSharedPreferences(configPath, Context.MODE_PRIVATE);

        } catch (Exception e) {
            e.printStackTrace();

        }

        return share;
    }

    public static String setProperties(Context context, String keyName, String keyValue) {
        try {
            share = context.getSharedPreferences(configPath, Context.MODE_PRIVATE);
            SharedPreferences.Editor editor = share.edit();//取得编辑器
            editor.putString(keyName, keyValue);//存储配置 参数1 是key 参数2 是值
            editor.commit();//提交刷新数据


        } catch (Exception e) {
            e.printStackTrace();
            Log.e("setPropertiesError", e.toString());
            return "修改配置文件失败!";
        }
        return "设置成功";
    }


}

 

封装

package com.**.demo.json;

import android.content.Context;
import android.content.SharedPreferences;
import com.**.demo.utils.UrlConfig;

/**
 * 网络请求
 */

public class UrlString {

    private static final String IP = "192.168.1.10:8000";

    private String contrastIPName = "contrastIP";

    // 上传路径
    private String ip;
    private String ipAddress;

    public void setIPAddress(Context context) {
        //Properties proper = ProperTies.getProperties(context);
        //this.ip = proper.getProperty(contrastIPName, "");
        SharedPreferences proper = UrlConfig.getProperties(context);
        this.ip = proper.getString(contrastIPName, "");
        // 设置默认值
        if (this.ip.equals("")){
            this.ip = IP;
        }
        this.ipAddress = "http://" + this.ip + "/v1.0/index.html";
    }

    public String setIPAddress(Context context, String keyValue) {
        // String result = ProperTies.setProperties(context, contrastIPName, keyValue);
        String result = UrlConfig.setProperties(context, contrastIPName, keyValue);
        this.ip = keyValue;
        this.ipAddress = "http://" + this.ip + "/v1.0/index.html";
        return result;
    }

    public String getIP() {
        return this.ip;
    }

    public String getIPAddress() {
        return this.ipAddress;
    }
}
