BottomNavigationBar-更改选项卡图标的颜色 [英] BottomNavigationBar-change the tab icon color

问题描述

我已在我的应用程序中集成了底部栏导航栏。但是当我滑动时，标签的颜色不会改变。我有选择器文件，这很奇怪。有解决这个问题的主意吗？

I've integrated Bottom Bar Navigation bar on my app. But when I swipe, tab's color doesn't change. It's weird cause I have selector file. Any idea to solve this problem?

Activity.java

BottomNavigationView bottomNavigationView = (BottomNavigationView)
            findViewById(R.id.bottom_navigation);


    bottomNavigationView.setOnNavigationItemSelectedListener(
            new BottomNavigationView.OnNavigationItemSelectedListener() {
                @Override
                public boolean onNavigationItemSelected(@NonNull MenuItem item) {
                    switch (item.getItemId()) {
                        case R.id.bb_menu_arac:
                            fragment = new AraclarimFragment();
                            break;
                        case R.id.bb_menu_yaklasan:
                            fragment = new YaklasanlarFragment();
                            break;
                        case R.id.bb_menu_yakin:
                            fragment = new Yakinimdakiler();
                            break;

                    }
                    final FragmentTransaction transaction = fragmentManager.beginTransaction();
                    transaction.replace(R.id.main_container, fragment).commit();
                    return true;
                }


            });

selector.xml

<?xml version="1.0" encoding="utf-8"?>
<selector xmlns:android="http://schemas.android.com/apk/res/android">
<item android:color="@color/beyaz" android:state_enabled="true" />
<item android:color="@color/colorPrimaryDark" android:state_enabled="false" />
</selector>

activiy.xml

<android.support.design.widget.BottomNavigationView
    android:id="@+id/bottom_navigation"
    android:layout_width="match_parent"
    android:layout_height="wrap_content"
    android:layout_gravity="bottom|end"
    app:itemBackground="@color/colorPrimary"
    app:itemIconTint="@color/beyaz"
    app:itemTextColor="@color/beyaz"
    app:menu="@menu/bottombar_menu" />

推荐答案

更改为 app：itemIconTint = @ drawable / selector

也将您的 selector.xml 更改为此：

<?xml version="1.0" encoding="utf-8"?>
<selector xmlns:android="http://schemas.android.com/apk/res/android">
<item android:state_checked="true" android:color="@color/beyaz" />
<item android:color="@color/colorPrimaryDark"  />
</selector>
