即使我的 @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); } } 是正确的，我仍然收到此错误。我不知道是不是图标。

这是我的MainActivity.java。我输入了所有需要的内容。

app:menu="@menu/bottom_navigation"

这是我的activity_main_user.xml。每当我删除 <com.google.android.material.bottomnavigation.BottomNavigationView android:id="@+id/bot_nav" android:layout_width="match_parent" android:layout_height="70dp" android:layout_alignParentBottom="true" android:background="#B9B9B9" android:backgroundTint="#1B000000" android:clipChildren="false" app:itemHorizontalTranslationEnabled="false" app:itemTextColor="#000000" app:menu="@menu/bottom_navigation" /> 时，Logcat中都不会显示错误。

    <?xml version="1.0" encoding="utf-8"?>
    <menu xmlns:android="http://schemas.android.com/apk/res/android">
        <item
            android:id="@+id/nav_home"
            android:icon="@mipmap/homeicon_ec"
            android:title="Home" />
        <item
            android:id="@+id/nav_search"
            android:icon="@mipmap/search_bottom_nav"
            android:title="Search" />
        <item
            android:id="@+id/nav_account"
            android:icon="@mipmap/ec_userlogo_bottom_nav_03"
            android:title="My Account" />
        <item
            android:id="@+id/nav_settings"
            android:icon="@mipmap/settings_bottom_nav"
            android:title="Settings" />
    </menu>

这是我的bottom_navigator.xml

这就是我在Logcat中得到的东西，

2 个答案:

答案 0 :(得分：1)

您怀疑问题与图标有关，因此您尝试删除它们吗？
如果您仔细查看日志，将会看到

Caused by: java.lang.OutOfMemoryError: 
 Failed to allocate a 10015740 byte allocation with 7465824 free bytes and 7MB until OOM

然后我们看到问题出在

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。似乎太大了，几乎没有图标。
尝试调整可绘制图像的大小。我怀疑您需要它们那么大。

答案 1 :(得分：0)

可以看到，内存不足错误。 它与您附加菜单中的图标之一有关。 

     Caused by: java.lang.OutOfMemoryError: Failed to allocate a 10015740 byte allocation with 7465824 free bytes

图片很大-10015740字节为9.56 MB，对于一个图标来说，这实在太大了。

请尝试减小图标的大小。
