无法从sharedpreferences文件中获取所有键和值

Question

每当我试图在Map中存储密钥时，我都会收到错误并且文件强制停止..

@Override
    protected void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.content_date_detail_activity);


        //getting name of file from intent
        Intent in = getIntent();

        String date= in.getStringExtra("Date");

 //Date is the file name of preference i got from there is no error in this line
        SharedPreferences sharedPreferences = getSharedPreferences(date, MODE_PRIVATE);

        //These line causing error
        Map<String,?> keys = sharedPreferences.getAll();

        for(Map.Entry<String,?> entry : keys.entrySet()){
            Log.d("map values", entry.getKey() + ": " +
                    entry.getValue().toString());
        }

    }

这些是我得到的错误
