我在Android上有exoplayer的应用程序。我已经创建了youtube的双击手势,可以通过动画向前或向后跳10秒!如何在双击上创建具有波纹效果的半圆?
像这样
这该怎么做?
最佳答案
我也想实现这种功能,所以我自己写了它以“复制” YouTube的行为。几乎一样。您可以在此处找到包含示例应用程序的库:https://github.com/vkay94/DoubleTapPlayerView
这些指令是用README编写的,但是由于Stackoverflow的原理:
0)要求:
1)将其包括在gradle 中(它托管在jitpack.io上,因此您必须将其添加到存储库中):
allprojects {
repositories {
...
maven { url 'https://jitpack.io' }
}
}
dependencies {
implementation 'com.github.vkay94:DoubleTapPlayerView:1.0.0'
}
2)在XML内添加 View :<FrameLayout
xmlns:android="http://schemas.android.com/apk/res/android"
xmlns:app="http://schemas.android.com/apk/res-auto"
android:layout_width="match_parent"
android:layout_height="match_parent" >
<com.github.vkay94.dtpv.DoubleTapPlayerView
android:id="@+id/playerView"
android:layout_width="match_parent"
android:layout_height="match_parent"
app:dtpv_controller="@+id/youtube_overlay" />
<com.github.vkay94.dtpv.youtube.YouTubeOverlay
android:id="@+id/youtube_overlay"
android:layout_width="match_parent"
android:layout_height="match_parent"
android:visibility="invisible"
app:yt_playerView="@+id/playerView" />
</FrameLayout>
3)在 Activity 中进行设置:youtube_overlay
.performListener(object : YouTubeOverlay.PerformListener {
override fun onAnimationStart() {
// Do UI changes when circle scaling animation starts (e.g. hide controller views)
youtube_overlay.visibility = View.VISIBLE
}
override fun onAnimationEnd() {
// Do UI changes when circle scaling animation starts (e.g. show controller views)
youtube_overlay.visibility = View.GONE
}
})
// Uncomment this line if you haven't set yt_playerView in XML
// .playerView(playerView)
// Uncomment this line if you haven't set dtpv_controller in XML
// playerView.controller(youtube_overlay)
// Call this method whenever the player is released and recreated
youtube_overlay.player(simpleExoPlayer)
