膨胀类material.bottomnavigation.BottomNavigationView时出错

时间：2019-02-10 15:30:59

标签： java android bottomnavigationview androidx

我正在尝试实现BottomNavigationView，我知道关于同一问题有多个答案，但是似乎没有一个对我有用。

我遵循了这个doc

在预览模式下，出现此错误

ThisWorkbook.Worksheets(1).Range("K1").Value = False
    Do While ThisWorkbook.Worksheets(1).Range("K1").Value = False
    DoEvents
    Loop

当我运行TestActivity时，出现了使类膨胀的错误

  • 可绘制对象位于 res / drawable
    • 中
  • 菜单位于 res /菜单

从不同帖子的答案中我可以理解，这是一个资源问题。

我试图删除每个资源调用，但是即使仅定义了宽度和高度，我仍然会收到错误消息。

TestActivity 

IllegalArgumentException: Unknown color

test.xml 

import android.os.Bundle;
import androidx.appcompat.app.AppCompatActivity;
import pt.myapp.android.myapp.R;

public class TestActivity extends AppCompatActivity {

    @Override
    protected void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.test);
    }
}

bottom_navigation_menu 

<FrameLayout

    app:itemIconTint="@drawable/bottom_navigation_colors"
    app:itemTextColor="@drawable/bottom_navigation_colors"

bottom_navigation_colors.xml

            android:icon="@drawable/page"
            android:title="page"
            app:showAsAction="always" />

</menu>

渐变

使用活动主题Theme.MaterialComponents.DayNight

答案 1 :(得分：0)

在BottomNavigationView中，由于XML可能导致膨胀错误，它可能位于@layout，@drawable，@style或@color文件夹中。 

<com.google.android.material.bottomnavigation.BottomNavigationView        
android:id="@+id/bottom_navigation"
android:layout_width="match_parent"
android:layout_height="56dp"
android:layout_gravity="bottom"
android:background="@color/colorPrimary"
app:itemIconTint="@drawable/bottom_navigation_colors"
app:itemTextColor="@drawable/bottom_navigation_colors"
app:menu="@menu/bottom_navigation_menu" />

此行可能引起充气错误： app:menu="@menu/bottom_navigation_menu"

我通过将可绘制文件保存在两个文件夹中来解决了该问题：

  1. 可绘制
  2. drawable-v24

答案 2 :(得分：0)

请确保将可绘制对象放在res/drawable文件夹中，而不要放在res/drawable-24中。我遇到了类似的问题，并且通过将文件移动到res/drawable文件夹中，错误消失了。

答案 3 :(得分：0)

采用您的样式，然后删除“ android：textColorSecondary”。 这应该可以解决您的问题。
