Android viewpager TextureView inside viewPager上无视频（仅声音）
我试图在viewpager中显示视频或图像，它是listview的一项。 当图像正确显示时，视频只播放声音，没有视频。 我尝试过使用VideoView和SurfaceView，但没有成功。 我不想用碎片来做这个 在listview中，出于测试原因，我加载了一组图像和一个视频。 图像加载良好，但视频仅播放声音 我认为这与它没有正确设置其表面结构有关，但我无法理解 任何帮助都将不胜感激 这是我的密码：Android viewpager TextureView inside viewPager上无视频（仅声音）,android-viewpager,textureview,Android Viewpager,Textureview,我试图在viewpager中显示视频或图像，它是listview的一项。 当图像正确显示时，视频只播放声音，没有视频。 我尝试过使用VideoView和SurfaceView，但没有成功。 我不想用碎片来做这个 在listview中，出于测试原因，我加载了一组图像和一个视频。 图像加载良好，但视频仅播放声音 我认为这与它没有正确设置其表面结构有关，但我无法理解 任何帮助都将不胜感激 这是我的密码： public class MediaSliderPagerAdapter2 extends Pag

@fadden:谢谢您的帮助，但我的SquareTextureView自定义视图出现了问题： 我已将onMeasure函数更改为：
@Override
protected void onMeasure(int width, int height) {
super.onMeasure(width, height);
int measuredWidth = getMeasuredWidth();
setMeasuredDimension(measuredWidth, measuredWidth);
}
我不知道为什么会发生这种情况（如果有人知道答案，请随意评论，这样我们可以从中学习一些东西），但我很高兴它起了作用：）如果您对视频播放代码进行评论，然后用画布渲染到TextureView上，您看到了什么吗？这将告诉您问题是与视频渲染有关还是与TextureView的显示有关。
