我已將BottomNavigationView
添加到我的項目中,並且我想向其中一個菜單項添加動畫。這個動畫是一個AnimationDrawable
,基本上是一系列的圖像。我已經完成了以下工作,但沒有工作,我怎麼能夠達到這個目標,或者嘗試一種替代方案?將AnimationDrawable添加到BottomNavigationView
main_activity.xml:
<?xml version="1.0" encoding="utf-8"?>
<RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android"
xmlns:app="http://schemas.android.com/apk/res-auto"
android:id="@+id/lytMain"
android:layout_width="match_parent"
android:layout_height="match_parent">
<FrameLayout
android:id="@+id/lytContent"
android:layout_width="match_parent"
android:layout_height="match_parent"
android:layout_marginBottom="?attr/actionBarSize" />
<android.support.design.widget.BottomNavigationView
android:id="@+id/nav"
android:layout_width="match_parent"
android:layout_height="?attr/actionBarSize"
android:layout_alignParentBottom="true"
android:background="@color/white"
app:menu="@menu/menu" />
</RelativeLayout>
menu.xml文件:
<?xml version="1.0" encoding="utf-8"?>
<menu xmlns:android="http://schemas.android.com/apk/res/android"
xmlns:app="http://schemas.android.com/apk/res-auto">
<item
android:id="@+id/menShow"
android:enabled="true"
android:icon="@drawable/headphones"
android:title="@string/menu_listen"
app:showAsAction="ifRoom" />
<item
android:id="@+id/menSearch"
android:enabled="true"
android:icon="@drawable/search"
android:title="@string/menu_search"
app:showAsAction="ifRoom" />
<item
android:id="@+id/menPlay"
android:enabled="true"
android:icon="@drawable/play_anim"
android:title="@string/menu_play"
app:showAsAction="ifRoom" />
</menu>
play_anim.xml:
<?xml version="1.0" encoding="utf-8"?>
<animation-list xmlns:android="http://schemas.android.com/apk/res/android"
android:id="@+id/play_anim"
android:oneshot="false">
<item
android:drawable="@drawable/vis_f1"
android:duration="100" />
<item
android:drawable="@drawable/vis_f2"
android:duration="100" />
<item
android:drawable="@drawable/vis_f3"
android:duration="100" />
<item
android:drawable="@drawable/vis_f4"
android:duration="100" />
<item
android:drawable="@drawable/vis_f5"
android:duration="100" />
<item
android:drawable="@drawable/vis_f6"
android:duration="100" />
<item
android:drawable="@drawable/vis_f7"
android:duration="100" />
</animation-list>
MainActivity.java:
BottomNavigationView bottomView = (BottomNavigationView) findViewById(R.id.nav);
MenuItem menuItem = (MenuItem) bottomView.findViewById(R.id.menPlay);
AnimationDrawable animation = (AnimationDrawable)menuItem.getIcon();
animation.start();
迄今爲止的結果是帶有3個靜態圖像的菜單,我只想爲它們中的一個製作動畫。
任何幫助將不勝感激,在此先感謝
