即使 bottom_navigation.xml 是正确的，但在展开底部导航视图时出错
Error when inflating Bottom Navigation View even though the bottom_navigation.xml is right
尽管我的 bottom_navigation.xml 是正确的，但我还是收到了这个错误。不知道是不是图标
这是我的MainActivity.java。我输入了所有需要的内容。
@Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main_user);
BottomNavigationView bottomNavigationView = findViewById(R.id.bot_nav);
bottomNavigationView.setOnNavigationItemSelectedListener(new BottomNavigationView.OnNavigationItemSelectedListener() {
@Override
public boolean onNavigationItemSelected(@NonNull MenuItem menuItem) {
int id = menuItem.getItemId();
if (id== R.id.nav_home){
}
if (id== R.id.nav_account){
}
if (id== R.id.nav_search){
}
if (id== R.id.nav_settings){
}
return true;
}
});
bottomNavigationView.setSelectedItemId(R.id.nav_home);
}
}
这是我的activity_main_user.xml。每当我删除 app:menu="@menu/bottom_navigation" 时，Logcat.
中没有显示任何错误

您怀疑问题与图标有关，那么您尝试删除它们了吗？
如果您仔细查看日志，您会看到
Caused by: java.lang.OutOfMemoryError:
Failed to allocate a 10015740 byte allocation with 7465824 free bytes and 7MB until OOM
然后我们发现问题出在
at android.content.Context.getDrawable(Context.java:525)
所以问题确实出在图标上。
10015740 字节超过 10MB。对于几个图标来说似乎太大了。
尝试调整可绘制图像的大小。我怀疑你需要它们那么大。
正如你所看到的，存在内存不足错误。
它与您附加的菜单中的一个图标有关。
Caused by: java.lang.OutOfMemoryError: Failed to allocate a 10015740 byte allocation with 7465824 free bytes
图片太大了 - 10015740 字节是 9.56 MB，这对于一个图标来说太大了。
请尝试减小图标大小。
