每当我按回键时，我的应用程序都会崩溃。基本上我有4个片段，但只有当它返回到我的第一个片段时才会崩溃。

代码 -
@Override
public void onBackPressed() {
DrawerLayout drawer = (DrawerLayout) findViewById(R.id.drawer_layout);
if (drawer.isDrawerOpen(GravityCompat.START)) {
drawer.closeDrawer(GravityCompat.START);//line 161
} else {
super.onBackPressed();
}
}

我认为地图片段部分是部分崩溃的应用程序。请看看
答案 0 :(得分：0)
您的错误发生在这里：
com.app.minicabscouk.HomeActivity.onBackPressed(HomeActivity.java:161)
HomeActivity的第161行。如果您仍然无法自己解决问题，那么您需要发布该课程的代码。
在这里查看第一行：
FATAL EXCEPTION: main Process: , PID: 5835 android.view.InflateException: Binary XML file line #16: Error inflating class fragment at android.view.LayoutInflater.createViewFromTag(LayoutInflater.java:770)
这是你的实际问题。无论您尝试创建哪个片段，第16行的XML都存在问题。
