Style
Attention: Something wrong on Android 4.x
With ViewPager
Add ViewBadger
Center Floating Action Button
compileSdkVersion
>= 25
Step 1. Add it in your root build.gradle at the end of repositories:
allprojects {
repositories {
...
maven { url "https://jitpack.io" }
}
}
Step 2. Add the dependency
- new version AndroidX
implementation 'com.github.uiuang:BottomNavigationViewEx:1.0.1'
- AndroidX use new version,and add config into gradle.properties
android.useAndroidX=true
android.enableJetifier=true
Downloading BottomNavigationViewEx.java and copying it to you project.
Adding a custom widget in xml
:
<com.uiuang.bottomnavigationviewex.BottomNavigationViewEx
android:id="@+id/bnve"
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:layout_alignParentBottom="true"
android:background="@color/colorPrimary"
app:itemIconTint="@color/selector_item_color"
app:itemTextColor="@color/selector_item_color"
app:menu="@menu/menu_navigation_with_view_pager" />
Binding view in Activity
:
BottomNavigationViewEx bnve = (BottomNavigationViewEx) findViewById(R.id.bnve);
bnve.enableAnimation(false);
bnve.enableShiftingMode(false);
bnve.enableItemShiftingMode(false);
bnve.enableOnLongClick(true);
bnve.setIconSize(widthDp, heightDp);
bnve.setTextSize(sp);
// set adapter
adapter = new VpAdapter(getSupportFragmentManager(), fragments);
bind.vp.setAdapter(adapter);
// binding with ViewPager
bind.bnve.setupWithViewPager(bind.vp);
- Add badge lib
compile 'q.rorbin:badgeview:1.1.0'
- Bind bottom view
// add badge addBadgeAt(2, 1); private Badge addBadgeAt(int position, int number) { // add badge return new QBadgeView(this) .setBadgeNumber(number) .setGravityOffset(12, 2, true) .bindTarget(bind.bnve.getBottomNavigationItemView(position)) .setOnDragStateChangedListener(new Badge.OnDragStateChangedListener() { @Override public void onDragStateChanged(int dragState, Badge badge, View targetView) { if (Badge.OnDragStateChangedListener.STATE_SUCCEED == dragState) Toast.makeText(BadgeViewActivity.this, R.string.tips_badge_removed, Toast.LENGTH_SHORT).show(); } }); }
You can see the demo.
Other usage is the same as official BottomNavigationView
.
You can click here for detail.
If you are using ProGuard you might need to add the following option:
-keep public class com.google.android.material.bottomnavigation.BottomNavigationView { *; }
-keep public class com.google.android.material.bottomnavigation.BottomNavigationMenuView { *; }
-keep public class com.google.android.material.bottomnavigation.BottomNavigationPresenter { *; }
-keep public class com.google.android.material.bottomnavigation.BottomNavigationItemView { *; }
The lib is based on BottomNavigationView
in AndroidX material
.
I found it was inflexible when I tried the demo. For example, I couldn't change the currently checked item through code. So I wrote a class to extend it to provide some useful methods.
You have no need to worry about stability, because I minimised the modifications through reflection.
