Question

请访问上面的链接或Click here以查看图片中的整个问题。由于声誉较低，我无法在此处添加图片。

在此给定图像中，存在两个视图

1：VideoView for Media

2：SurfaceView Camera的FrameLayout

正常工作：在活动启动时视频（VideoView for media）正在屏幕上正常播放，前置摄像头（FrameLayout用于摄像头）也在右上角使用VideoView 即VideoView中的FrameLayout（在VideoView的右上角）

如果我们点击＆＃34;按钮＆＃34;然后frameLayout越来越大，videoview越来越小，反之亦然。即现在VideoView with FrameLayout（在FrameLayout的右上角）

问题如果点击按钮所有功能正常工作，即VideoView越来越小，FrameLayout越来越大但反之亦然VideoView越来越大，FrameLayout越来越小但现在相机视图不可见。实际上它是VideoView的背景......在这里我无法让它可见。或将FrameLayout置于VideoView之上。

我在这里使用了所有可能的解决方案，但无法解决此问题。

所以任何人都可以帮助让它变得可见？

我还附上了代码请帮助。

.java文件

mVideoView11 = (VideoView)rootview.findViewById(R.id.videoview11);
myCameraPreview = (FrameLayout)rootview.findViewById(R.id.frame_video_camera);



    public void onClick(View v) {
            if(v == button2){
                changeLayout();
            }else if(v == button3){
                changeLayoutAgain();
            }
    }

// for large Camera view(FrameLayout)
    public void changeLayout(){

                RelativeLayout.LayoutParams head_params1 = (RelativeLayout.LayoutParams)mVideoView11.getLayoutParams();
                head_params1.setMargins(400, 20, 10, 0);
                head_params1.addRule(RelativeLayout.ALIGN_PARENT_TOP, RelativeLayout.TRUE);
                head_params1.addRule(RelativeLayout.ALIGN_PARENT_RIGHT, RelativeLayout.TRUE);


                head_params1.height=360;
                head_params1.width=200;

                mVideoView11.setLayoutParams(head_params1);
                head_params1 = null;

                // Camera view

                RelativeLayout.LayoutParams head_params = (RelativeLayout.LayoutParams)myCameraPreview.getLayoutParams();
                head_params.setMargins(0, 250, 0, 5);
                head_params.addRule(RelativeLayout.CENTER_HORIZONTAL, RelativeLayout.TRUE);
                head_params.width=500;
                head_params.width = head_params.FILL_PARENT;


                myCameraPreview.setLayoutParams(head_params);
                head_params = null;

            }



    // For large VideoView

        public void changeLayoutAgain(){

                // for large video view
                RelativeLayout.LayoutParams head_params1 = (RelativeLayout.LayoutParams)mVideoView11.getLayoutParams();
                head_params1.setMargins(0, 250, 0, 5);
                head_params1.addRule(RelativeLayout.CENTER_HORIZONTAL, RelativeLayout.TRUE);
                head_params1.height=500;
                head_params1.width = head_params1.FILL_PARENT;

                mVideoView11.setLayoutParams(head_params1);
                head_params1 = null;

                // Camera view
                RelativeLayout.LayoutParams head_params = (RelativeLayout.LayoutParams)myCameraPreview.getLayoutParams();
                //head_params.setMargins(500, 20, 5, 5);
                head_params.addRule(RelativeLayout.ALIGN_PARENT_TOP, RelativeLayout.TRUE);
                head_params.addRule(RelativeLayout.ALIGN_PARENT_RIGHT, RelativeLayout.TRUE);
                head_params.height=200;
                head_params.width=200;

                myCameraPreview.setLayoutParams(head_params);
                head_params = null;

            }

.xml文件

<VideoView
        android:id="@+id/videoview11"
        android:layout_width="fill_parent"
        android:layout_height="200dp"
        android:layout_alignParentLeft="true"
        android:layout_alignParentTop="true"
        android:visibility="visible" />

    <FrameLayout
        android:id="@+id/frame_video_camera"
        android:layout_width="80dp"
        android:layout_height="80dp"
        android:layout_alignParentRight="true"
        android:layout_alignParentTop="true"
        android:background="#ff0000"
        android:visibility="visible" >
    </FrameLayout>

我想在Android中动态更改某些视图的顺序
