bottomnavigationviewex's Issues

Exclude android:label attr from Android Manifest

Cannot use library since it uses the label attr in its own Android Manifest.

Error:Execution failed for task ':mobile:processDebugManifest'.

Manifest merger failed : Attribute application@label value=(@string/title_app) from AndroidManifest.xml:18:13-46
is also present at [com.github.ittianyu:BottomNavigationViewEx:1.1.2] AndroidManifest.xml:13:9-41 value=(@string/app_name).
Suggestion: add 'tools:replace="android:label"' to element at AndroidManifest.xml:7:5-58:19 to override.

Custom typeface only works for the selected item

Really cool extensions for BottomNavigationView. I'm having an issue with setting a custom font.

I'm using the following code:

Typeface typeface = Typeface.createFromAsset(getAssets(), "fonts/SourceSansPro/SourceSansPro-Bold.ttf");
bnve.setTypeface(typeface);

The font SourceSansPro-Bold is only applied to the selected item. All other items remain in the default font.

Keep all item as unselected by default with Bottom Navigation

Basically i want to keep all item as unselected or unchecked by default. I had tried a lot unable to do so,

I tried the following link ,

https://stackoverflow.com/questions/41372293/bottomnavigationview-how-to-uncheck-all-menuitems-and-keep-titles-being-displa

but with this solution i got the following opened issue,
#25

Any help would be greatly appreciated.

Have you checked with Android Support v25.4.0?

There are significant changes in Android Support v25.4.0 where some classes are made internal :(.

Have you checked?

Is it possible to change icon when select and unselect

I want to set different icon when i select menu and also in unselect icon

Hidden menu item (visibility gone) still takes space in the Bottom Navigation

I have 4 menu items in the bottom navigation but I have set first item's visibility gone. But this is not allowing the remaining 3 icons to take full remaining space.
Can you suggest a solution for this issue?
How to set effect for the hidden icon like there are only three icons?
My use case is:
having 4 views in view pager, 1st view is not related to the bottom navigation, remaining 3 are selected with the bottom navigation.
But setting 3 items in navigation, will show the first item as selected but view pager will show the view not related to the selected item.
Thank you.

Badge not working

I am trying to add support for badging in bottom navigation view. As per your examples you used "ActivityBadgeViewBinding" , but this class does not exisit anywhere in library. Pleas help to resolve this.

6666666666666666

厉害咧大神。就是搞不懂Google为什么不把这些方法暴露出来，因为还是有不需要位移的需要的。以后要是Google开发了api你就是功臣了。

怎么添加对badge的支持？

能提供个思路也行，就是一个小红点那种。

ActivityWithViewPagerBinding where ?

Hello,

Where is the ActivityWithViewPagerBinding ?

Thanks

How can I hide the badge?? Hide() doesn't work

I'm trying to remove the badge but hide() (used into setOnDragStateChangedListener) method doesn't seem to work.

Thank you, nice library.

是否支持下滑隐藏？

Question: Possible different item icon/color?

Sometimes an active item and its inactive state might use different icons, in different shape and different color. Is this possible?

Bottom Navigation View padding

How can i set the View padding top and bottom using setTextVisibility(false);? The bar height is so small. Thank you.

切换存在BUG

从0切到3然后切回第0个第2个的文字直接就消失了。

Center icon only not show

I use icon this , but not show when set center icon only. Help me

Thanks Alo

建议增加单独Item的setIconVisibility的方法

目前的setIconVisibility针对所有BottomNavigationItemView设置。希望能增加类似setIconVisibility（int position ,boolean visibility）的方法控制Item的显示与隐藏.
ps:虽然也可以自己在代码里面获取到BottomNavigationItemView后设置visibility，但是会出现Item宽度间隔不一的问题。

If content scrolls, is behavior not supported?

I want to embed the webview in the content and hide the bottom navigation when it scrolls down.
Does not this library support such a function?

"No field mAnimationHelper" error is thrown in the console in version 26.0.0 of the design support lib

When running an app with design support 26.0.0, the following lengthy stacktrace shows up in the logcat:

Any way to add more than 5 items?

It would be helpful and the best library if you can modify it to have more than 5 items in bottom bar.

切换icon时，文字会闪烁多次

用手滑动的时候，底部的菜单没有变化，当开启动画的时候，滑动到最边缘的时候。

用手滑动的时候，底部的菜单没有变化，当开启动画的时候，滑动到最边缘的时候。
我开启了所有动画，然后，滑动viewpager，当到最边缘的时候，并不能将菜单缩小到相应的位置。

快速切换文字消失什么时候可以解决呢

提个小问题

Set icons top and bottom margin (center icons vertically)

First of all, a big THANK YOU for your work on this library ❤️ ! The framework API is just too much to handle and I saved a lot of time thanks to BottomNavigationViewEx.

I have a question regarding centering of the menu items in the menu.
Is there a way to give them the same top and bottom margin/center them vertically? I am using setIconsMarginTop(int x) to style top margin, but I couldn't find anything similar for styling the bottom margin.

Appreciate your help.

Problem with badges in fragment

it looks like this and I'm figured that action bar height is returning 0.

在NestedScrollView中能不能固定在屏幕底部

我的Root View是NestedScrollView，使用BottomNavigationView或Ex都会排到内容底部，不是屏幕底部。layout_gravity 或者 alignParentBottom 都无效～
有什么方法固定在屏幕底部么？谢谢。

Ripple effect

There is a way to maintain the Ripple Effect after removing the shifting mode?

I'm using this configuration:

bottomNavigationView.enableAnimation(false);
bottomNavigationView.enableShiftingMode(false);
bottomNavigationView.enableItemShiftingMode(false);
bottomNavigationView.setTextVisibility(true);
bottomNavigationView.setIconVisibility(true);

I don't want any kind of Shifting but I want to continue having the ripple effect.

Thank you and amazing job!

Badge not showing up properly

Hello,

Thanks for making an excellent library public. I tried using the nugget package and everything (animation, shifting) works fine but I am having issue with the Badge functionality.

I implemented exactly as per the code sample but in my case badge is not appearing and also the respective icon is getting reduced in size. Attached please find a screen shot for the same.

Kindly advise.

android:allowBackup conflict

The manifest of this library sets allowBackup to true. This value may conflict with the manifest of app. I think this line can be deleted from the manifest of the library because it is not required.

Error log:

Error:Execution failed for task ':app:processDebugManifest'.
> Manifest merger failed : Attribute application@allowBackup value=(false) from AndroidManifest.xml:10:9-36
	is also present at [com.github.ittianyu:BottomNavigationViewEx:1.1.3] AndroidManifest.xml:12:9-35 value=(true).
	Suggestion: add 'tools:replace="android:allowBackup"' to <application> element at AndroidManifest.xml:8:5-28:19 to override.

Icon and label vanishes/fades a little with animation/shift/itemshift disable

Having a bug if I press the buttons fast enough (not slow but not very fast) it vanishes/fades a little of his original color.

Badger example

Due that the BadgerView used in the example is deprecated, I started looking for an alternative. I found this one:

https://github.com/AlexLiuSheng/BadgeView

I changed a little your example code and apparently it works just fine. Could you give it a try?

Thank you!

NPE when calling BottomNavigationViewEx.getItemCount()

If you call BottomNavigationViewEx.getItemCount() before inflating a menu, you'll get a NullPointerException. Seems like you should get 0 in that case.

Allow various features to be defined through XML attributes

It would be nice if the various feature setters such as setTextVisibility() or setLargeTextSize() could be provided in XML, for instance as app:textVisibility.

I'm using it like in onCreate:


ButterKnife.bind(this);

navigation.enableShiftingMode(false);
navigation.enableItemShiftingMode(false);
navigation.setTextVisibility(false); navigation.setOnNavigationItemSelectedListener(mOnNavigationItemSelectedListener);

After adding BadgeView icon goes down

I tried to use BadgeView with BottomNavigationViewEx.
I used code like this:

bottomNavigationView.enableAnimation(false);
bottomNavigationView.enableItemShiftingMode(false);
bottomNavigationView.enableShiftingMode(false);

private BadgeView addBadgeViewAt(int position, String text, int shape) {
        // get position
        ImageView icon = bottomNavigationView.getIconAt(position);
        int[] pos = new int[2];
        icon.getLocationInWindow(pos);
        // action bar height
        ActionBar actionBar = getSupportActionBar();
        int actionBarHeight = 0;
        if (null != actionBar) {
            actionBarHeight = actionBar.getHeight();
        }
        int x = (int) (pos[0] + icon.getMeasuredWidth() * 0.7f);
        int y = (int) (pos[1] - actionBarHeight - icon.getMeasuredHeight() * 1.25f);
        // calculate width
        int width = 16 + 4 * (text.length() - 1);
        int height = 16;

        BadgeView badgeView = BadgeFactory.create(this)
                .setTextColor(Color.WHITE)
                .setWidthAndHeight(width, height)
                .setBadgeBackground(Color.RED)
                .setTextSize(10)
                .setBadgeGravity(Gravity.RIGHT | Gravity.TOP)
                .setBadgeCount(text)
                .setShape(shape)
                .setSpace(1, 1)
                .bind(icon);
//        badgeView.setX(x);
//        badgeView.setY(y);
        return badgeView;
    }

At first badge looks good.

But when I start to click on BottomNavigationView icon goes down, and stays there.

Caused by: org.xmlpull.v1.XmlPullParserException: Binary XML file line #1: invalid drawable tag vector

Please fix

Vertical center

Vertical center normalization is fucked up. If the navgiation is e.g. 48dp, your icons are 20+dp, they get aligned a bit to the bottom rather than shifted to the top so it can be vertically aligned. Can we have the option to shift the offset of the menu items? OR even better: to let BottomNavigationViewEx do that behind the scenes automatically for us?

Drop min SDK to 9

Hi there,

I was wondering if you could elaborate on the reason for having a minSdk of 11. It seems to have been so since your initial commit, but it seems to compile/lint fine when I drop the minSdk to 9. Given the support library supports down to 9, would you consider dropping the minSdk to 9 for this library too?

Cheers.

app:itemIconTint only works for item in state_checked=true for APIs above KitKat

Having an issue with app:itemIconTint: colors from the xml selector are only applied to items that are in state_checked=true. The ones that are not are not colored. This only happens for APIs ABOVE KitKat.

Here's how I define my BottomNavigationView:

<com.ittianyu.bottomnavigationviewex.BottomNavigationViewEx
    android:id="@+id/bottomNavView"
    android:layout_width="match_parent"
    android:layout_height="wrap_content"
    android:layout_alignParentBottom="true"
    android:background="@android:color/white"
    android:paddingBottom="@dimen/bottom_nav_menu_margin"
    app:elevation="@dimen/bottomview_elevation"
    app:itemIconTint="@@color/bottom_nav_button"
    app:itemTextColor="@color/bottom_nav_button"
    app:layout_constraintBottom_toBottomOf="parent"
    app:menu="@menu/bottombar_menu" />

My selector, that resides in res/color:

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

I also tried with other possible states, but I learned that for BottomNavigationView it's indeed state_checked that we should work with.
I also tried using @drawable instead of @color, and also with
<item android:color="@color/colorPrimaryLight" android:state_checked="false"/> explicitly, but still no luck.

Any help appreciated and thank you for your work on this time-saving library!

能不能设置没有点击阴影呢

如题，item项点击都有阴影效果，去掉是否需要修改源码

text is not visible along with icon

I have done following coding

bottomNavigationView.enableAnimation(false);
bottomNavigationView.enableShiftingMode(false);
bottomNavigationView.enableItemShiftingMode(false);

but text is only visible on selected icon. how to show text for all icons.

My android version is 6.0.1 (Mi Note3)

当ViewPager里添加了多于bottomNavigationView的items数量时，会报index our of bound

您好，当我用自带的BottomNavigationView的时候，我的底部菜单里只有3个items（buttons），但是我可以在ViewPager里设置多于3个fragments。例如，我在adapter里添加了五个fragments，而BNV里只有3个items。
但是，当我用BottomNavigationViewEx的时候，会报出index out of bound错误。
请问是否可以添加setItems数量的方法？
抑或您有什么好的解决方案？
多谢

需求是底部导航栏的icon默认是灰色，选中是橙色渐变的效果，用这个框架后，图片被强制渲染成主题色，怎么解决？或者说，我想两张图片png的来切换选中未选中的icon，不要把我的icon强制再渲染上一层色，该怎么做？
