请试试这个。我希望这可能会产生您想要的结果。

我需要全屏播放视频

【参考方案2】：

制作您的自定义 VideoView 类

public class FullScreenVideoView extends VideoView 
    public FullScreenVideoView(Context context) 
        super(context);
    

    public FullScreenVideoView(Context context, AttributeSet attrs) 
        super(context, attrs);
    

    public FullScreenVideoView(Context context, AttributeSet attrs, int defStyle) 
        super(context, attrs, defStyle);
    

    @Override
    protected void onMeasure(int widthMeasureSpec, int heightMeasureSpec)
        super.onMeasure(widthMeasureSpec, heightMeasureSpec);
        setMeasuredDimension(widthMeasureSpec, heightMeasureSpec);
    

    public void setFixedVideoSize(int width, int height)
    
        getHolder().setFixedSize(width, height);
    

并在您的 Layout 中设置 VideoView

<yourpackage.FullScreenVideoView
                android:id="@+id/VideoView"
                android:layout_
                android:layout_
                />

【参考方案3】：

做这样的事情

@Override
    public void onConfigurationChanged(Configuration newConfig) 
        super.onConfigurationChanged(newConfig);
        Logger.debug(TAG, "onConfigChanged");
        updateLayout(newConfig.orientation);
    

 /**
     * Update the current layout params according to current device orientation.
     */
    private void updateLayout(int orientation) 
        LinearLayout.LayoutParams favParams = (LinearLayout.LayoutParams) mFavoriteLayout.getLayoutParams();
        LinearLayout.LayoutParams historyParams = (LinearLayout.LayoutParams) mHistoryLayout.getLayoutParams();
        LinearLayout.LayoutParams colParams = (LinearLayout.LayoutParams) mColumnLayout.getLayoutParams();
        if (orientation == Configuration.ORIENTATION_PORTRAIT) 
            mColumnLayout.setOrientation(LinearLayout.VERTICAL);
            historyParams.width = favParams.width = ViewGroup.LayoutParams.MATCH_PARENT;
            historyParams.height = favParams.height = 0;
            colParams.weight = 1.0f;
         else if (orientation == Configuration.ORIENTATION_LANDSCAPE) 
            mColumnLayout.setOrientation(LinearLayout.HORIZONTAL);
            historyParams.height = favParams.height = ViewGroup.LayoutParams.MATCH_PARENT;
            historyParams.width = favParams.width = 0;
            colParams.weight = 2.0f;
        

        // Set back updated params and redraw
        mFavoriteLayout.setLayoutParams(favParams);
        mHistoryLayout.setLayoutParams(historyParams);
        mColumnLayout.setLayoutParams(colParams);
        mColumnLayout.invalidate();
    

当你改变方向改变重量，你就能达到你想要的。

【参考方案4】：

这很简单。您可以在创建新的“全屏活动”时找到一个示例。

是这样的：

// Hide UI first
    ActionBar actionBar = getSupportActionBar();
    if (actionBar != null) 
        actionBar.hide();
    
    mContentView.setSystemUiVisibility(View.SYSTEM_UI_FLAG_LOW_PROFILE
            | View.SYSTEM_UI_FLAG_FULLSCREEN
            | View.SYSTEM_UI_FLAG_LAYOUT_STABLE
            | View.SYSTEM_UI_FLAG_IMMERSIVE_STICKY
            | View.SYSTEM_UI_FLAG_LAYOUT_HIDE_NAVIGATION
            | View.SYSTEM_UI_FLAG_HIDE_NAVIGATION);
