我在我的Android应用程序中使用BottomBar菜单。 BottomBar中有5个菜单。这是主要活动

public class MainActivity extends BaseActivity {
    private static final String TAG = "MainActivity";
    private static final String COMMAND_RESET_PASSWORD = "reset-password";
    private static final String COMMAND_REFERRAL = "referral";
    private static final int HOME = 0;
    private static final int MAP = 1;
    private static final int DEAL = 2;
    private static final int NOTIFICATION = 3;
    private static final int SETTINGS = 4;
    private BottomBar mBottomBar;
    private int mCurrentTab = HOME;
    private BottomBarBadge mNotificationBadge;
    private boolean mActive;
    @Override
    protected void onCreate(Bundle savedInstanceState) {
        mActive = true;

        handleIntent(intent);
    }

        mBottomBar = BottomBar.attach(this, savedInstanceState);
        mBottomBar.useFixedMode();
        mBottomBar.noTabletGoodness();

在标签之间切换时(Bottombar菜单)导致应用程序在某些设备中崩溃。但我无法重现异常。

快速解决方案是对您正在为当前活动所做的所有FragmentTransactions使用<script src="https://ajax.googleapis.com/ajax/libs/jquery/2.1.0/jquery.min.js"></script> <table id="mytable"></table>而不是。.commitAllowingStateLoss();

答案 1 :(得分:2)

有一个与之相关的错误:https://issuetracker.google.com/issues/36932872

要保存实例并向outState Bundle添加内容,可以使用以下命令:

@Override
protected void onSaveInstanceState(Bundle outState) {
    outState.putString("WORKAROUND_FOR_BUG_KEY","WORKAROUND_FOR_BUG_VALUE");
    super.onSaveInstanceState(outState);
}

如果不起作用,也尝试添加此行:

transaction.commitAllowingStateLoss();

答案 2 :(得分:1)

我遇到过这个问题

对于那些片段状态已丢失的.commitAllowingStateLoss();,我使用.commit();代替FragmentTransaction

在另一个课程中,您可以使用.commit();
