問題描述:Android VideoView播放視訊豎屏切換橫屏有黑邊無法全屏

解決辦法是自定義VedioView,動態設定寬高。
* 1.自定義VedioView,並在onMeasure中新增

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

完整程式碼如下

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);
        //此處設定的預設值可隨意,因為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);
    }
}

僅僅新增上述程式碼還是有問題,最底部還是有黑邊

• 2.再在程式碼中橫豎屏切換的時候新增

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

完整程式碼如下

   /**
     * 監聽螢幕方向改變
     * @param newConfig
     * 配置檔案配置了configChanges才會走次此回撥
     */
    @Override
    public void onConfigurationChanged(Configuration newConfig) {
        super.onConfigurationChanged(newConfig);
        //配置檔案中設定 android:configChanges="orientation|screenSize|keyboardHidden" 不然橫豎屏切換的時候重新建立又重新播放
        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);//顯示頂部狀態列
            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 顯示頂部狀態列
            getWindow().addFlags(WindowManager.LayoutParams.FLAG_FORCE_NOT_FULLSCREEN);
        }
        System.out.println("======onConfigurationChanged===");
    }
