SurfaceView播放器篇三

实现功能： 1、下次进入，从上一次播放位置开始播放； 2、来电保存视频进度； 3、视频未看部分不能快进； 4、适应视频大小，防止播放画面变形； 5、播放与暂停按钮； 6、按home键、查看最新打开应用键，back返回键后，再次回到或打开播放页面，不报错，能正常播放。 解决问题： 1、避免MediaPlayer error（-38， 0）,MediaPlayer error（-19， 0）; 2、避免Mediaplayer setVideoSurfaceTexture failed: -22问题； 3、避免进入onError回调函数后，Mediaplayer的start(),pause()方面无效果； 4、Mediaplayer onCompletion后 再次start后 再调用pause无暂停效果，还是会继续播放。 解决思路： Mediaplayer和SurfaceView都重新new一个，一切重新开始。 实现代码： import android.content.SharedPreferences; import android.media.MediaPlayer; import android.os.Bundle; import android.os.Handler; import android.os.Message; import android.support.v7

I've implemented the commonly-pointed-to VerticalSeekBar post here . As it is, the SeekBar operates a little quirky. Here is my slightly adapted onTouchEvent() from that example: public boolean onTouchEvent(MotionEvent event) { xPos = event.getX(); yPos = event.getY(); oOffset = this.getThumbOffset(); oProgress = this.getProgress(); //Code from example - Not working //this.setThumbOffset( progress * (this.getBottom()-this.getTop()) ); this.setProgress((int)(29*yPos/this.getBottom())); return true; } I've managed to implement one VerticalSeekBar in which the progress updates as expected and is

Modifying the Android seekbar widget to operate vertically

由 ぃ、小莉子 提交于 2019-11-26 08:11:53
问题 I\'m trying to get a vertical seekbar going with the emulator, but I\'m sort of stuck. I can get the seekbar to display the way I want it to, and I can get the progress to do what I want, and I can modify the onTouchEvent to get the thumb to go vertically instead of horizontally. What I can\'t do is get the thumb to move outside of the default 29 horizontal pixels without using setThumbOffset(). This in itself isn\'t a problem. The problem is coming from the fact that I don\'t understand the
