如何为共享首选项创建共享库

Question

我正在开发一个包含大量模块的应用程序，我需要从我在:app应用程序中创建的名为SharedPrefManager的SharedPreference类加载数据，该应用程序是我将其他模块实现到名为:mediplan的模块中的应用程序，我只想检索我保存在SharedPrefManager中的ID。

我试图在有问题的模块中实现依赖项:mediplan但我最终出现了很多错误，所以我回去删除了依赖项。

SharedPrefManager类：

package com.example.tuteur;
import android.content.Context;
import android.content.Intent;
import android.content.SharedPreferences;
public class SharedPrefManager {
    private static final String SHARED_PREF_NAME = "CIN";
    private static final String IDCONT = "con";
    private static final String malade = "malade";
    private static SharedPrefManager mInstance;
    private static Context ctx;
    public SharedPrefManager(Context context) {
        ctx = context;
    }
    public static synchronized SharedPrefManager getInstance(Context context) {
        if (mInstance == null) {
            mInstance = new SharedPrefManager(context);
        }
        return mInstance;
    }
    public void setIdCont(String id) {
        SharedPreferences sharedPreferences = ctx.getSharedPreferences(SHARED_PREF_NAME, Context.MODE_PRIVATE);
        SharedPreferences.Editor editor = sharedPreferences.edit();
        editor.putString(IDCONT, id);
        editor.apply();
    }
    //this method will give the logged in user
    public String getIdCont() {
        SharedPreferences sharedPreferences = ctx.getSharedPreferences(SHARED_PREF_NAME, Context.MODE_PRIVATE);
        return sharedPreferences.getString(IDCONT, null);
    }

    //this method will give the logged in user
    public void setMalade(String malade) {
        SharedPreferences sharedPreferences = ctx.getSharedPreferences(SHARED_PREF_NAME, Context.MODE_PRIVATE);
        SharedPreferences.Editor editor = sharedPreferences.edit();
        editor.putString(malade, malade);
        editor.apply();
    }
    //this method will give the logged in user
    public String getMalade() {
        SharedPreferences sharedPreferences = ctx.getSharedPreferences(SHARED_PREF_NAME, Context.MODE_PRIVATE);
        return sharedPreferences.getString(malade, null);
    }
    //this method will log the user out
    public void logout() {
        SharedPreferences sharedPreferences = ctx.getSharedPreferences(SHARED_PREF_NAME, Context.MODE_PRIVATE);
        SharedPreferences.Editor editor = sharedPreferences.edit();
        editor.clear();
        editor.apply();
    }
}

我找到的解决方案是使用 put extras 和 put bundle 而不是使用共享库
