我正在设置一个有两个视图的框架布局——一个是 ImageView,另一个是相机预览。这是代码:
public void setUpCamera(){
//Set cameraView as the camera preview class
cameraView = new CameraPreview(getApplicationContext());
//Set imageResult as an image
imageResult = new ImageView(getApplicationContext());
imageResult.setBackgroundColor(Color.GRAY);
//Prime the frame and buttons from the xml file
frameLayout = (FrameLayout) findViewById(R.id.camera_preview);
snapPhoto = (Button) findViewById(R.id.button_capture);
//Add both camera preview and the snapped picture to the FrameLayout in the xml file
frameLayout.addView(imageResult);
frameLayout.addView(cameraView);
frameLayout.bringChildToFront(imageResult);
现在我的问题是是否可以将cameraView“隐形”添加到FrameLayout中?这是一件小事,但是在设置相机时,您会在通过bringChildToFront 方法将图像带到前台之前获得相机预览模式的闪光。
任何想法将不胜感激!
