//初始化videoview控制条
mediaController=newMediaController(this);
//设置videoview的控制条

//设置显示控制条
mediaController.show(0);
//设置播放完成以后监听
videoView.setOnCompletionListener(newMediaPlayer.OnCompletionListener(){

videoView.setVideoURI(uri);
//设置为全屏模式播放
setVideoViewLayoutParams(2);
}

/**
*设置videiview的全屏和窗口模式

*/
publicvoidsetVideoViewLayoutParams(intparamsType){
//全屏模式
if(1==paramsType){
//设置充满整个父布局
RelativeLayout.LayoutParamsLayoutParams=newRelativeLayout.LayoutParams(RelativeLayout.LayoutParams.MATCH_PARENT,RelativeLayout.LayoutParams.MATCH_PARENT);
//设置相对于父布局四边对齐
LayoutParams.addRule(RelativeLayout.ALIGN_PARENT_BOTTOM);
LayoutParams.addRule(RelativeLayout.ALIGN_PARENT_TOP);
LayoutParams.addRule(RelativeLayout.ALIGN_PARENT_LEFT);
LayoutParams.addRule(RelativeLayout.ALIGN_PARENT_RIGHT);
//为VideoView添加属性
videoView.setLayoutParams(LayoutParams);
}else{
//窗口模式
//获取整个屏幕的宽高

//设置窗口模式距离边框50

}
}

/**
*页面暂停效果处理
*/
@Override
protectedvoidonPause(){
super.onPause();
//如果当前页面暂停则保存当前播放位置，全局变量保存

//停止回放视频文件

}

/**
*页面从暂停中恢复
*/
@Override
protectedvoidonResume(){
super.onResume();
//跳转到暂停时保存的位置
