在最新版本的 Android 发布之前，我的应用程序最近在所有方面都运行良好。Google Pixel 现在因以下代码而崩溃。我正在尝试使用 Caldroid 日历解决方案，使用它非常棒。但是，当我尝试替换 Fragment 并对其进行操作时，它现在崩溃了.commit()。

在阅读了无数关于这个问题的堆栈文章之后，我仍然没有看到我做错了什么。

这是我的onCreate：

@Override
protected void onCreate(Bundle savedInstanceState) {
    super.onCreate(savedInstanceState);
    setContentView(R.layout.activity_schedule);
    context=this;
    initComponents();
    getSharedData();

    getAllGameData();

    addCaldroidCalendar();
}

和 addCaldroidCalendar 函数：

public void addCaldroidCalendar() {

    caldroidFragment = new CaldroidFragment();

    Calendar calendar = Calendar.getInstance();

    // setup arguments for calendar view
    Bundle args = new Bundle();
    args.putInt(CaldroidFragment.MONTH, calendar.get(Calendar.MONTH) + 1);
    args.putInt(CaldroidFragment.YEAR, calendar.get(Calendar.YEAR));
    args.putBoolean(CaldroidFragment.SQUARE_TEXT_VIEW_CELL, false);
    caldroidFragment.setArguments(args);

    android.support.v4.app.FragmentTransaction t = getSupportFragmentManager().beginTransaction();
    t.replace(R.id.calendar1, caldroidFragment);
    t.commitNow();

}

这是我的 UI XML：

        </RelativeLayout>


    </RelativeLayout>

</RelativeLayout>

这会导致以下崩溃：

                      at com.android.internal.os.ZygoteInit.main(ZygoteInit.java:767)

如果我注释掉以下行onCreate：

t.commitNow();

然后它可以工作，但显然我的日历没有出现

这是最新版本的 Android 的问题，之前没有任何问题。可能会发生什么变化，我可能做错了什么？这个让我完全难住了。

好吧，从您的日志中您可以看到这是因为它无法在运行时解析按钮中的颜色资源。就像测试一样，删除 XML 中的背景属性。
