将SharedPreferences迁移到新的SharedPreferences

// 创建新的SharedPreferences对象
SharedPreferences newSharedPreferences = getApplicationContext().getSharedPreferences("newSharedPreferences", Context.MODE_PRIVATE);

// 获取旧的SharedPreferences对象
SharedPreferences oldSharedPreferences = getApplicationContext().getSharedPreferences("oldSharedPreferences", Context.MODE_PRIVATE);

// 获取旧的SharedPreferences中的所有键值对
Map<String, ?> allEntries = oldSharedPreferences.getAll();

// 将旧的键值对存储到新的SharedPreferences中
SharedPreferences.Editor editor = newSharedPreferences.edit();
for (Map.Entry<String, ?> entry : allEntries.entrySet()) {
    String key = entry.getKey();
    Object value = entry.getValue();
    if (value instanceof String) {
        editor.putString(key, (String) value);
    } else if (value instanceof Integer) {
        editor.putInt(key, (Integer) value);
    } else if (value instanceof Boolean) {
        editor.putBoolean(key, (Boolean) value);
    } // 其他类型的数据根据需要进行处理
}

// 提交更改
editor.commit();
