弹幕简便模版,

直接上依赖:

compile 'com.github.ctiao:DanmakuFlameMaster:0.5.3'

控件:

<master.flame.danmaku.ui.widget.DanmakuView    android:layout_marginTop="650dp"    android:id="@+id/danmakuview_show"    android:layout_width="match_parent"    android:layout_height="350dp" />

主的:

全局变量:

@BindView(R.id.danmakuview_show)DanmakuView danmakuView;private boolean showDanmaku;private DanmakuContext danmakuContext;private BaseDanmakuParser parser = new BaseDanmakuParser() {    @Override    protected IDanmakus parse() {        return new Danmakus();    }};int h = 0;String ss = "这件商品不错!";

Activity的代码:

//弹幕danmakuView.enableDanmakuDrawingCache(true);danmakuView.setCallback(new DrawHandler.Callback() {    @Override    public void prepared() {        showDanmaku = true;        danmakuView.start();        generateSomeDanmaku();    }    @Override    public void updateTimer(DanmakuTimer timer) {    }    @Override    public void danmakuShown(BaseDanmaku danmaku) {    }    @Override    public void drawingFinished() {    }});danmakuContext = DanmakuContext.create();danmakuView.prepare(parser, danmakuContext);
