我保持获取默认值要么我的UI将显示为null,要么我使用整数它显示默认值以及它在字符串形式plz帮助

//putting the information in shared preferencesTextVIEw pscore1=(TextVIEw)findVIEwByID(R.ID.pscore1f);SharedPreferences peepsscores2= PreferenceManager.getDefaultSharedPreferences(GamePlayFirst.this);SharedPreferences.Editor editor2 =peepsscores2.edit();String userscore11 = pscore1.getText().toString();  editor2.putString("userscore11",userscore11);  editor2.commit();  //getting it and editing it  SharedPreferences peepsscores2 = PreferenceManager.getDefaultSharedPreferences(this);    int u;    int one =1;    int newUsrscore1=1;    String userscore11 = peepsscores2.getString("userscore11",null);    u=Integer.parseInt(userscore11);        newUsrscore1 = u+one;        String newUserscore1  = Integer.toString(newUsrscore1);    SharedPreferences.Editor editor = peepsscores2.edit();    editor.putString(newUserscore1, NewUserscore1);      editor.commit();    //getting it and displaying it on the UI    SharedPreferences peepsscores2 = PreferenceManager.getDefaultSharedPreferences(this);    String userscore11 = peepsscores2.getString("Newuserscore1",null);  pscore1.setText(" "+userscore11);

解决方法:

我已经为您添加了一些评论代码,请检查：

//putting the information in shared preferencesTextVIEw pscore1=(TextVIEw)findVIEwByID(R.ID.pscore1f);SharedPreferences peepsscores2= PreferenceManager.getDefaultSharedPreferences(GamePlayFirst.this);SharedPreferences.Editor editor2 =peepsscores2.edit();String userscore11 = pscore1.getText().toString();  editor2.putString("userscore11",userscore11);  editor2.commit();  //getting it and editing it  SharedPreferences peepsscores2 = PreferenceManager.getDefaultSharedPreferences(this);    int u;    int one =1;    int newUsrscore1=1;    String userscore11 = peepsscores2.getString("userscore11",null);    u=Integer.parseInt(userscore11);        newUsrscore1 = u+one;        String newUserscore1  = Integer.toString(newUsrscore1);    SharedPreferences.Editor editor = peepsscores2.edit();     //@Praful: here newUserscore1 seems to be integer value and you are storing     //null here. I think it it should be     //`editor.putString("Newuserscore1", newUsrscore1);`    editor.putString(newUserscore1, null);     //@Praful: call commit here    editor.commit;    //getting it and displaying it on the UI    SharedPreferences peepsscores2 = PreferenceManager.getDefaultSharedPreferences(this);    String userscore11 = peepsscores2.getString("Newuserscore1",null);  pscore1.setText(" "+userscore11);
