Question

我的代码有一个问题，我可以使用一些帮助。我制作了一个跟踪足球比赛统计数据的应用程序。应用程序工作正常，问题是当我旋转手机屏幕时出现2个问题：布局与屏幕宽度不匹配，使文本和按钮相互重叠，当我转动手机时，由于某种原因，分数重置。我有一个重置按钮，但我不知道为什么它在我旋转屏幕时激活。会感激一些帮助。谢谢阅读！这是XML和Java中的代码：

public class MainActivity extends AppCompatActivity {
int golosA = 0;
int faltasA = 0;
int forasDeJogoA = 0;
int cartoesAmarelosA = 0;
int expulsoesA = 0;
int golosB = 0;
int faltasB = 0;

Answer 1

我不是100％肯定，但我的直觉告诉我你需要添加一个onOrientationChanged监听器，并在水平/横向模式下再次将文本设置为相同的值。

它与活动生命周期有关，当方向发生变化时，如果您不保存这些值或设置值，它会暂时停止/暂停（不确定哪个）活动，然后将它们设置为默认值在你的代码中像0一样。

Answer 2

有关分数重置问题，请尝试添加以下行：

<activity android:name=".YourActivity"
        android:configChanges="orientation|screenSize" >

进入您的清单文件。它告诉您的活动不对屏幕方向更改做出反应。它仍然会旋转，但会阻止变量重置。

对于旋转问题，您是否尝试过编辑应用的旋转版本？我不知道您正在使用哪种编辑器，但在Android Studio的“设计”页面中，您可以选择创建横向版本并手动更改其设计。

旋转时如何使布局填满屏幕？
