No static field BottomNavigationView_itemTextAppearanceInactive

[haemi]

After updating my kotlin version I get

E/AndroidRuntime: Caused by: java.lang.NoSuchFieldError: No static field BottomNavigationView_itemTextAppearanceInactive of type I in class Lcom/google/android/material/R$styleable; or its superclasses (declaration of 'com.google.android.material.R$styleable' appears in /data/app/~~_uI0dg3nC4c_eEwo8fl8nQ==/com.package.my-nUTdjiOK-2ESwQyBPFue2w==/base.apk!classes3.dex)

        at com.ittianyu.bottomnavigationviewex.BottomNavigationViewEx.<init>(BottomNavigationViewEx.java:21)

What am I missing here?

Kotlin 1.7.0 Google Material 1.6.1

Copy the files BottomNavigationViewEx.java and BottomNavigationViewInner.java to your project, then in BottomNavigationViewInner.java make the styleable like this:

public BottomNavigationViewInner(Context context, AttributeSet attrs, int defStyleAttr) {
        super(context, attrs, defStyleAttr);
        TintTypedArray a = ThemeEnforcement.obtainTintedStyledAttributes(context, attrs,
                com.google.android.material.R.styleable.BottomNavigationView,
                defStyleAttr, com.google.android.material.R.style.Widget_Design_BottomNavigationView,
                new int[]{com.google.android.material.R.styleable.NavigationBarView_itemTextAppearanceInactive,
                        com.google.android.material.R.styleable.NavigationBarView_itemTextAppearanceActive});
        // clear if you don't have set item icon tint list
        if (!a.hasValue(com.google.android.material.R.styleable.NavigationBarView_itemIconTint)) {
            clearIconTintColor();
        }
        a.recycle();
    }

Changes for:

• com.google.android.material.R.styleable.NavigationBarView_itemTextAppearanceInactive
• com.google.android.material.R.styleable.NavigationBarView_itemTextAppearanceActive
• com.google.android.material.R.styleable.NavigationBarView_itemIconTint

1.
BottomNavigationViewInner中

    private BottomNavigationItemView[] mButtons;
改为
    private NavigationBarItemView[] mButtons;

对应修改BottomNavigationViewEx方法返回值

2.构造方法
public BottomNavigationViewInner(Context context, AttributeSet attrs, int defStyleAttr) {
        super(context, attrs, defStyleAttr);
        TintTypedArray a = ThemeEnforcement.obtainTintedStyledAttributes(context, attrs,
                com.google.android.material.R.styleable.BottomNavigationView,
                defStyleAttr, com.google.android.material.R.style.Widget_Design_BottomNavigationView,
                com.google.android.material.R.styleable.NavigationBarView_itemTextAppearanceInactive,
                com.google.android.material.R.styleable.NavigationBarView_itemTextAppearanceActive);
        // clear if you don't have set item icon tint list
        if (!a.hasValue(com.google.android.material.R.styleable.NavigationBarView_itemIconTint)) {
            clearIconTintColor();
        }
        a.recycle();
    }

3.修改如下方法
private <T> T getField(Class targetClass, Object instance, String fieldName) {
        try {
            Field field = null;
            while (targetClass != null && !targetClass.getName().toLowerCase().equals("java.lang.object")) {
                for (Field f : targetClass.getDeclaredFields()) {
                    if (f.getName().equals(fieldName)) {
                        field = f;
                        break;
                    }
                }
                if (field != null)
                    break;
                targetClass = targetClass.getSuperclass(); //得到父类,然后赋给自己
            }

            if (field == null)
                return null;
//            Field field = targetClass.getDeclaredField(fieldName);
            field.setAccessible(true);
            return (T) field.get(instance);
        } catch (Exception e) {
            e.printStackTrace();
        }
        return null;
    }

private void setField(Class targetClass, Object instance, String fieldName, Object value) {
        try {
            Field field = null;
            while (targetClass != null && !targetClass.getName().toLowerCase().equals("java.lang.object")) {
                for (Field f : targetClass.getDeclaredFields()) {
                    if (f.getName().equals(fieldName)) {
                        field = f;
                        break;
                    }
                }
                if (field != null)
                    break;
                targetClass = targetClass.getSuperclass(); //得到父类,然后赋给自己
            }

            if (field == null)
                return;
//            Field field = targetClass.getDeclaredField(fieldName);
            field.setAccessible(true);
            field.set(instance, value);
        } catch (IllegalAccessException e) {
            e.printStackTrace();
        }
    }
