玩家工作正常。但是当设备锁定并且活动恢复时，播放器没有恢复播放。请帮我解决此问题。 提前谢谢。

尝试使用以下代码更改简历
@Override
protected void onResume() {
//satatus bar color setting
if (Build.VERSION.SDK_INT >= Build.VERSION_CODES.LOLLIPOP) {
Window window = getWindow();
window.setStatusBarColor(Color.TRANSPARENT);
}
if (isresume) {
isresume=false;
player.stop();
player.clearVideoSurface();
isInPlayer = false;
seekto = Constants.playerPosition;
initPlayer();
loadPlayer();
} else {
loadPlayer();
}
super.onResume();
}
