I have my bottomNavigationView :
And i added this class to prevent it from doing shiftingMode :
public class BottomNavigationViewHelper {
public static void disableShiftMode(BottomNavigationView view) {
BottomNavigationMenuView menuView = (BottomNavigationMenuView) view.getChildAt(0);
try {
Field shiftingMode = menuView.getClass().getDeclaredField("mShiftingMode");
shiftingMode.setAccessible(true);
shiftingMode.setBoolean(menuView, false);
shiftingMode.setAccessible(false);
for (int i = 0; i < menuView.getChildCount(); i++) {
BottomNavigationItemView item = (BottomNavigationItemView) menuView.getChildAt(i);
//noinspection RestrictedApi
item.setShiftingMode(false);
// set once again checked value, so view will be updated
//noinspection RestrictedApi
//item.setChecked(item.getItemData().isChecked());
}
} catch (NoSuchFieldException e) {
Log.e("BNVHelper", "Unable to get shift mode field", e);
} catch (IllegalAccessException e) {
Log.e("BNVHelper", "Unable to change value of shift mode", e);
}
}
I just want to show the original icons colors without this selector, how i can reach this ?
my navigation xml :
<android.support.design.widget.BottomNavigationView
android:id="@+id/bottomNavigation"
android:layout_width="match_parent"
android:layout_height="wrap_content"
app:menu="@menu/my_navigation_item"
android:layout_alignParentBottom="true"/>
你必须让你的项目图标 tint list null
,你从你的 bootomNav 到达它:
bottomNavigationView.setItemIconTintList(null);
如果您使用 Kotlin,您会怎么做 从您的主活动中找到您的导航 ID,然后在您的 mainActivity onCreat 中使用此代码
my_navigation_item.itemIconTintList = null
Our use case was a multicolored icon when the tab is active and a grey one when it is not. Setting itemIconTintList
to null made the inactive tab icons have the same colors as the active ones when using the material component BottomNavigationView
.
So we had to do this in addition:
menu_bottom_navigation.xml:
<?xml version="1.0" encoding="utf-8"?>
<menu xmlns:android="http://schemas.android.com/apk/res/android">
<item
android:id="@+id/first_tab"
android:enabled="true"
android:icon="@drawable/ic_first_tab_selector"
android:title="@string/first_tab_title"/>
<item
android:id="@+id/second_tab"
android:enabled="true"
android:icon="@drawable/ic_second_tab_selector"
android:title="@string/second_tab_title"/>
</menu>
ic_first_tab_selector.xml:
<?xml version="1.0" encoding="utf-8"?>
<selector xmlns:android="http://schemas.android.com/apk/res/android">
<item android:drawable="@drawable/ic_first_tab_inactive" android:state_selected="false" />
<item android:drawable="@drawable/ic_first_tab_active" android:state_selected="true" />
</selector>
Where ic_first_tab_inactive.xml
is the drawable for your inactive icon and ic_first_tab_active.xml
is the drawable for your active icon.
You are able to use app:itemIconTint
from xmlns:app="http://schemas.android.com/apk/res-auto"
For example
<android.support.design.widget.BottomNavigationView
//...
app:itemIconTint="@color/gray_scale"
//...
/>
It is handy when your drawables have different colors
The accepted answer worked but that method is now deprecated.
The new way to enable the original icon colors is:
bottomNavigation.setForceTint(false);
