优先考虑是否复用问题。

我禁止了复用还是有这个问题

如果你是仿抖音的那种上下扒拉,我这边是这么做的.重点在那个滑动距离上,判断上下滑动50像素才算上下扒拉,这样就不会重新再去创建开始播放视频,而是JZVD的video还是原来那个.我估摸着大概可能也许是因为对同一个Jzvd没有销毁就直接在赋值使用造成的,但我在之前调用了Jzvd.releaseAllVideos()依旧没有生效,所以,如果有思路可以再回一下. `class NewViewPagerLayoutManager : LinearLayoutManager {

我的是类似皮皮虾那种视频图片文字混合的列表发现log中执行到onStatePlaying时textureViewContainer的宽高为0了当我滑动列表中断视频播放后在重新滑回来时重复2到3次就会出现此问题

public void onStatePlaying() { Log.i(TAG, "onStatePlaying " + " [" + this.hashCode() + "] "); if(null!=textureViewContainer.getChildAt(0)){ Log.d(TAG, "让我看看你的宽"+textureViewContainer.getChildAt(0).getWidth()); Log.d(TAG, "让我看看你的高"+textureViewContainer.getChildAt(0).getHeight()); if(0==textureViewContainer.getChildAt(0).getWidth()&&0==textureViewContainer.getChildAt(0).getHeight()){ state = STATE_NORMAL; clickStart(); }else { if (state == STATE_PREPARED) {//如果是准备完成视频后第一次播放，先判断是否需要跳转进度。 Log.d(TAG, "onStatePlaying:STATE_PREPARED "); mAudioManager = (AudioManager) getApplicationContext().getSystemService(Context.AUDIO_SERVICE); mAudioManager.requestAudioFocus(onAudioFocusChangeListener, AudioManager.STREAM_MUSIC, AudioManager.AUDIOFOCUS_GAIN_TRANSIENT); if (seekToInAdvance != 0) { mediaInterface.seekTo(seekToInAdvance); seekToInAdvance = 0; } else { long position = JZUtils.getSavedProgress(getContext(), jzDataSource.getCurrentUrl()); if (position != 0) { mediaInterface.seekTo(position);//这里为什么区分开呢，第一次的播放和resume播放是不一样的。这里怎么区分是一个问题。然后 } } } state = STATE_PLAYING; startProgressTimer(); } }
