java - 当我轮换应用程序时，评分栏会显示更多星星

Question

我的评级栏星星有一个奇怪的问题。

This is my app in vertical position

This is my app in horizontal position

正如你所看到的星星完全改变了

这是我的 xml 文件:

这是我的java代码:

Context ctx2 = this;
String[][] arrayWithInformations = new String[5][];
@Override
protected void onCreate(Bundle savedInstanceState) {
    super.onCreate(savedInstanceState);
    setContentView(R.layout.activity_nivo1);
    getSupportActionBar().setDisplayHomeAsUpEnabled(true);

    DatabaseOperations databaseOperations = new DatabaseOperations(ctx2);
    Cursor cursorLogo = databaseOperations.getInformationsForLogos(databaseOperations);
    // looping through all rows and adding to list
    Integer i = 0;
    if (cursorLogo.moveToFirst()) {
        do {
            String[] helperArray = {cursorLogo.getString(0),cursorLogo.getString(1),cursorLogo.getString(2),cursorLogo.getString(3),
                    cursorLogo.getString(4),cursorLogo.getString(5)};
            arrayWithInformations[i] = helperArray;
            i++;

        } while (cursorLogo.moveToNext());
    }
    int firstRating = Integer.parseInt(arrayWithInformations[0][4]);
    int secondRating = Integer.parseInt(arrayWithInformations[1][4]);
    int thirdRating = Integer.parseInt(arrayWithInformations[2][4]);
    int fourthRating = Integer.parseInt(arrayWithInformations[3][4]);
    RatingBar rb0 = (RatingBar) findViewById(R.id.rb0);
    rb0.setRating(firstRating);
    RatingBar rb1 = (RatingBar) findViewById(R.id.rb1);
    rb1.setRating(secondRating);
    RatingBar rb2 = (RatingBar) findViewById(R.id.rb2);
    rb2.setRating(thirdRating);
    RatingBar rb3 = (RatingBar) findViewById(R.id.rb3);
    rb3.setRating(fourthRating);

我从数据库文件中获取评级值，一切正常，星星没问题，但当我旋转手机时，它们都错了。我知道当您旋转手机时，当前 Activity 会再次加载，但它是相同的代码，并且加载错误。也许它正在增加星星..我可能听起来很有趣，但我不知道出了什么问题。请有人给我带路..

我发现问题了!

android:shrinkColumns="1,0" android:stretchColumns="0,1"

将其设置为TableLayout导致了这个奇怪的问题。

感谢大家有兴趣帮助我..
