Android Open Danmaku

一个Android的弹幕控件. Open Danmaku is a Android widget which shows danmaku animation(https://github.com/linsea/OpenDanmaku).

Usage

For a working implementation of this project see the sample app.

add library dependency to your build.gradle file.

            dependencies {
                compile 'com.linsea:opendanmaku:1.0.0@aar'
            }

Include the DanmakuView in your layout.

            <com.opendanmaku.DanmakuView
                android:id="@+id/danmakuView"
                android:layout_width="fill_parent"
                android:layout_height="fill_parent"
                app:start_Y_offset="0.2"
                app:end_Y_offset="0.8"
                app:max_row="4"
                app:max_running_per_row="2"
                app:pick_interval="1000"
                app:show_debug="false" />

In your Activity:

            mDanmakuView = (DanmakuView) findViewById(R.id.danmakuView);

            // add danmaku items:
            mDanmakuView.addItem(list, true);
            mDanmakuView.addItem(new DanmakuItem(this, "Hello World", mDanmakuView.getWidth());

            //show danmaku and play animation:
            mDanmakuView.show();

            //hide and pause playing:
            mDanmakuView.hide();

            //release all playing and waiting items:
            mDanmakuView.clear();

Customization

start_Y_offset first channel offset to the view top edge.
end_Y_offset last channel offset to the view top edge.
max_row max running channels on Y axis.
max_running_per_row max concurrent running items in one channel.
pick_interval interval millisecond picking up an item in the backing queue to play.

怎么暂停呢

我说的暂停是弹幕停止，停留在你点击的时候的位置，还是可见，并不是隐藏。而且停止之后还可以恢复

修改弹幕字体大小时出现黑色背景

我在发弹幕时修改了字体大小
IDanmakuItem item = new DanmakuItem(this, new SpannableString(input), mDanmakuView.getWidth(),0,R.color.my_item_color,18,1)
其他弹幕的字体大小是14号字，显示时会有黑色的背在弹幕上出现

在listView中使用弹幕库！

在listView的每个item中添加时弹幕库时，会将所有的item要显示的内容都全部显示出来，是复用的原因么？怎么解决呢？

一条弹道可以依法出现多条弹幕吗

目前是一条弹道一天数据完成后再加载另外一条，能不能加载到一半就加载另一条呢

DanmakuItem.willHit()有问题

如果这个item没有被draw，它的mContainerWidth就是0，这导致willHit()总是返回true。一条航道只能画一个弹幕。

    public boolean willHit(IDanmakuItem runningItem) {
        if (runningItem.getWidth() + runningItem.getCurrX() > mContainerWidth) {
            return true;
        }

        if (runningItem.getSpeedFactor()>= mFactor) {
            return false;
        }

        float len1 = runningItem.getCurrX() + runningItem.getWidth();
        float t1 = len1 / (runningItem.getSpeedFactor() * DanmakuItem.sBaseSpeed);
        float len2 = t1 * mFactor * DanmakuItem.sBaseSpeed;
        if (len2 > len1) {
            return true;
        } else {
            return false;
        }

    }
