我的评级栏星级有一个奇怪的问题。
这是我的应用程序在垂直位置
这是我的应用程序在水平位置
正如你所看到的,恒星完全改变了

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);
我从数据库文件中得到了评分值,一切都很好,星星还可以,但当我转动手机时,它们都错了。我知道that
当你旋转手机时,当前活动会再次加载,但它是相同的代码,加载错误。也许这是恒星的倍增。。我听起来可能很有趣,但我不知道出了什么问题。有人请给我一个线索。。
我发现了问题!
android:shrinkColumns="1,0"android:stretchColumns="0,1"
将其设置为TableLayout会导致此奇怪的问题。
感谢大家对我的帮助。。
