计算视频需要设置的比例
int displayWith = playLinearLayout.getWidth();//获取布局的宽度1280
int displayHeight = playLinearLayout.getHeight();//获取布局的高度720
mVideoWidth = mMediaPlayer.getVideoWidth();//视频的宽度640
mVideoHeight = mMediaPlayer.getVideoHeight();//视频的高度272
if (mVideoWidth != 0 && mVideoHeight != 0) {
/* 设置视频的宽度和高度 */
LinearLayout.LayoutParams params =
new LinearLayout.LayoutParams(displayWith, displayHeight);
//视频显示高度要重新调整
if (mVideoWidth*displayHeight > displayWith*mVideoHeight){
params.height = displayWith * mVideoHeight / mVideoWidth;
}//视频宽度要重新调整
else if (mVideoWidth*displayHeight < displayWith*mVideoHeight){
params.width = displayHeight * mVideoWidth / mVideoHeight;
}
else {
params.width = displayWith;
params.height = displayHeight;
}
m_SurfaceView.setLayoutParams(params);//设置surfaceview的大小，放大后是1280x544
m_SurfaceHolder.setFixedSize(params.width, params.height);
/* 开始播放 */
mediaPlayerPlay();
运行后，视频显示的大小是正确了，但是视频的上边是黑边，下边却是灰边，这灰边是怎么出现的？请大佬帮忙解决。
我的原始设计意图就是要视频按照正常比例缩放，避免全屏显示时，画面拉伸变形。
