Android VideoView播放视频竖屏切换横屏有黑白边无法全屏

问题描述:Android VideoView播放视频竖屏切换横屏有黑边无法全屏

解决办法是自定义VedioView,动态设置宽高。
* 1.自定义VedioView,并在onMeasure中添加

int width = getDefaultSize(0,widthMeasureSpec);
int height = getDefaultSize(0,heightMeasureSpec);
setMeasuredDimension(width,height);

完整代码如下

package vedioplay.csy.com.videoplay;

import android.content.Context;
import android.util.AttributeSet;
import android.widget.VideoView;

public class IVideoView extends VideoView {
    public IVideoView(Context context) {
        super(context);
    }

    public IVideoView(Context context, AttributeSet attrs) {
        super(context, attrs);
    }

    public IVideoView(Context context, AttributeSet attrs, int defStyleAttr) {
        super(context, attrs, defStyleAttr);
    }

    @Override
    protected void onMeasure(int widthMeasureSpec, int heightMeasureSpec) {
        super.onMeasure(widthMeasureSpec, heightMeasureSpec);
        //此处设置的默认值可随意,因为getDefaultSize中的size是有值的
        int width = getDefaultSize(0,widthMeasureSpec);
        int height = getDefaultSize(0,heightMeasureSpec);
        setMeasuredDimension(width,height);
        System.out.println("======onMeasure===width==="+width);
        System.out.println("======onMeasure===height==="+height);
    }
}

仅仅添加上述代码还是有问题,最底部还是有黑边

• 2.再在代码中横竖屏切换的时候添加

RelativeLayout.LayoutParams params = new RelativeLayout.LayoutParams(ViewGroup.LayoutParams.MATCH_PARENT, DensityUtil.dip2px(CustomPlayStyleActivity.this,300));
mVideoView.setLayoutParams(params);

完整代码如下

   /**
     * 监听屏幕方向改变
     * @param newConfig
     * 配置文件配置了configChanges才会走次此回调
     */
    @Override
    public void onConfigurationChanged(Configuration newConfig) {
        super.onConfigurationChanged(newConfig);
        //配置文件中设置 android:configChanges="orientation|screenSize|keyboardHidden" 不然横竖屏切换的时候重新创建又重新播放
        if (getResources().getConfiguration().orientation == Configuration.ORIENTATION_LANDSCAPE){
            RelativeLayout.LayoutParams params = new RelativeLayout.LayoutParams(ViewGroup.LayoutParams.MATCH_PARENT, ViewGroup.LayoutParams.MATCH_PARENT);
            mVideoView.setLayoutParams(params);

            getWindow().clearFlags(WindowManager.LayoutParams.FLAG_FORCE_NOT_FULLSCREEN);//显示顶部状态栏
            getWindow().addFlags(WindowManager.LayoutParams.FLAG_FULLSCREEN);
        }else if (getResources().getConfiguration().orientation == Configuration.ORIENTATION_PORTRAIT){
            RelativeLayout.LayoutParams params = new RelativeLayout.LayoutParams(ViewGroup.LayoutParams.MATCH_PARENT, DensityUtil.dip2px(CustomPlayStyleActivity.this,300));
            mVideoView.setLayoutParams(params);

            getWindow().clearFlags(WindowManager.LayoutParams.FLAG_FULLSCREEN);//全屏不 显示顶部状态栏
            getWindow().addFlags(WindowManager.LayoutParams.FLAG_FORCE_NOT_FULLSCREEN);
        }
        System.out.println("======onConfigurationChanged===");
    }
