Android live send gifts and send messages page (imitation of India live)

Introduction to the

The end of the year is coming, to everyone worship an early year, I wish everyone a good luck in the year of the chicken ~ ha ha dirty classmates face the wall! Without further ado, the effect implemented today is floating View when live streaming. I wonder if the SDK of live streaming all provides UI. Let’s take a look at a rendering:

Realize the effect drawing

(Of course, the live video is the main, here do not care about the video, the focus is the View, here just play a video at random.)

The first is a ListView that slides across the top to show the members of the room.
ListView automatically scrolls to the bottom;
Custom brush gift View, automatically disappear over a period of time;
DialogFragment+ViewPager+GridView;
[Fixed] Listen for events that pop up on the keyboard when clicking on a comment
[Fixed] Heart-sending effects are displayed at the bottom of the broadcast (third-party tyrant: Heartlayout is used here)
VedioView plays video;

The implementation process

The first thing to remember is that the video is at the bottom, and above the video is the View floating, so I’m using the ViewPager to right swipe to “hide” the View, which is actually toggling. Very simple layout:

<?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>Copy the code

Next, implement two fragments, one is a blank Fragment (NoFragment) and the other is a ChatFragment with various special effects, and then fill it into the ViewPager. Of course, it also needs to realize the video playback. Very simple VedioView, I won’t say more about ~

// Read the video from the Raw resource file
final String uri = ("android.resource://" + this.getPackageName() + "/raw/vedio");
videoView.setVideoURI(Uri.parse(uri));
videoView.start();
// The video can be looped
videoView.setOnCompletionListener(new MediaPlayer.OnCompletionListener() {
    @Override
    public void onCompletion(MediaPlayer mp) {
        videoView.setVideoURI(Uri.parse(uri)); videoView.start(); }});Copy the code

Let’s look at the main chatfragments:

Here you can see that the View that brushes the gift has been wrapped as a GiftItemView.

Handler+Runnable is used to execute timed tasks. When a gift is sent continuously, it is re-timed. ObjectAnimator is used to animate the number of gifts. Automatic scrolling for ListViews is a timed task that adds each Item to the ListView collection and then uses ListView.setSelection (int Adapter.getCount ()) to locate the last Item.

Interested can take a look at the source code: Github download address github has apK files can be downloaded to experience. If you have any questions, please point them out, thank you ~
