简介
年关将至,给大家拜个早年,祝大家鸡年大吉吧 ~ 哈哈 有污的同学面壁去吧!闲话不多说,今天实现的效果是直播的时候浮层View,不知道直播的sdk是不是都提供UI这方面的东西。先看一张效果图:
主要实现效果:
(当然直播的时候视频是主要的,这里不关心视频,重点是View,这里只是随意播放了一个视频。)
- 首先是顶部横线滑动的ListView显示房间的成员;
- ListView 自动滚动到底部;
- 自定义实现刷礼物的View,过段时间自动消失;
- 送礼物的时候弹出礼物的DialogFragment+ViewPager+GridView;
- 点击评论的时候监听弹出键盘的事件;
- 直播底部显示送心的特效(这里用了第三方的 tyrant:heartlayout);
- VedioView播放视频;
实现过程
首先需要清楚视频是出于最底部的,在视频上面浮着View,这里我用了ViewPager来实现右滑”隐藏“View,其实是切换。
很简单布局:
<?xml version="1.0" encoding="utf-8"?>
<RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:layout_width="match_parent"
android:layout_height="match_parent"
android:background="@drawable/wether_bg"
android:orientation="vertical">
<cm.wzh.live.view.MyVideoView
android:id="@+id/video"
android:layout_width="match_parent"
android:layout_height="match_parent" />
<android.support.v4.view.ViewPager
android:id="@+id/view_pager"
android:background="@null"
android:layout_width="match_parent"
android:layout_height="match_parent">
</android.support.v4.view.ViewPager>
</RelativeLayout>
接下来实现2个Fragment,一个是空白的Fragment(NoFragment ),一个是带有各种特效的Fragment(ChatFragment ),再填充到ViewPager里面去,当然这里还需要去实现视频的播放,很简单的VedioView,这里就不再多说~
//从Raw资源文件读取视频
final String uri = ("android.resource://" + this.getPackageName() + "/raw/vedio");
videoView.setVideoURI(Uri.parse(uri));
videoView.start();
//视频可以循环播放
videoView.setOnCompletionListener(new MediaPlayer.OnCompletionListener() {
@Override
public void onCompletion(MediaPlayer mp) {
videoView.setVideoURI(Uri.parse(uri));
videoView.start();
}
});
接下来看主要的ChatFragment :

主要是Handler+Runnable实现定时任务,当连续送礼物的时候再重新计时,用属性动画ObjectAnimator对送的数字缩放动画。
对于ListView自动滚动是定时任务每来一个Item就加到ListView集合里面,然后用listview.setSelection(int adapter.getCount())定位到最后一个Item。
有兴趣的可以看一下源代码: github下载地址 github上有apk文件可以下载体验下。
如果有什么问题,希望大家指出来,谢谢~
