Do any image processing in a background <code>AsyncTask</code>. This will allow your UI Activity to continue on and take another picture.

Edit: I cannot delete an accepted answer so please see stoefin's answer below. Calling <code>camera.startPreview()</code> before taking the next photo works for him.

blocks|key|887400|text|您可以编写自己的Activity，直接使用camera+API来完成您所描述的功能，而不是使用手机上现有的摄像头应用程序定义的Activity。Camera类的文档如下：http://developer.android.com/reference/android/hardware/Camera.html|type|unstyled|depth|inlineStyleRanges|entityRanges|offset|length|data|887401|entityMap|0|LINK|mutability|MUTABLE|url|http://developer.android.com/reference/android/hardware/Camera.html^0|2D|1V|0|0^^$0|@$1|2|3|4|5|6|7|L|8|@]|9|@$A|M|B|N|1|O]]|C|$]]|$1|D|3|-4|5|6|7|P|8|@]|9|@]|C|$]]]|E|$F|$5|G|H|I|C|$J|K]]]]

Instead of using the activities defined by the existing camera app on your phone, you can write your own Activity that uses the Camera API directly to accomplish the functionality you describe. The Camera class is documented here: <a href="http://developer.android.com/reference/android/hardware/Camera.html" rel="nofollow">http://developer.android.com/reference/android/hardware/Camera.html</a>

blocks|key|887429|text|我找到了一个解决方案:拍照后，预览显示将停止。若要拍摄更多照片，请先再次调用camera.startPreview()。|type|unstyled|depth|inlineStyleRanges|offset|length|style|CODE|entityRanges|data|887430|entityMap^0|12|L|0^^$0|@$1|2|3|4|5|6|7|H|8|@$9|I|A|J|B|C]]|D|@]|E|$]]|$1|F|3|-4|5|6|7|K|8|@]|D|@]|E|$]]]|G|$]]

I found a solution for this: After taking a picture, preview display will have stopped. To take more photos, call <code>camera.startPreview()</code> again first.

blocks|key|670371|text|照相机冻结，因为您没有重新启动照相机的预览，所以请通过调用camera.startpreview()重新启动它|type|unstyled|depth|inlineStyleRanges|offset|length|style|CODE|entityRanges|data|670372|entityMap^0|T|L|0^^$0|@$1|2|3|4|5|6|7|H|8|@$9|I|A|J|B|C]]|D|@]|E|$]]|$1|F|3|-4|5|6|7|K|8|@]|D|@]|E|$]]]|G|$]]

The camera is freezing, because you are not restarting the preview of the camera, so restart it by calling <code>camera.startpreview()</code>

blocks|key|887506|text|捕获图像后，应停止预览，然后重新开始预览。|type|unstyled|depth|inlineStyleRanges|entityRanges|data|887507|mCamera.stopPreview();
mCamera.startPreview();|code-block|syntax|javascript|887508|它会工作得很好。|887509|entityMap^0|0|0|0^^$0|@$1|2|3|4|5|6|7|K|8|@]|9|@]|A|$]]|$1|B|3|C|5|D|7|L|8|@]|9|@]|A|$E|F]]|$1|G|3|H|5|6|7|M|8|@]|9|@]|A|$]]|$1|I|3|-4|5|6|7|N|8|@]|9|@]|A|$]]]|J|$]]

after capturing image you should stop the preview and start it back again. 

<pre><code>mCamera.stopPreview();
mCamera.startPreview();
</code></pre>

it would work fine.

blocks|key|887576|text|camera.startpreview()；答案不适用于我的情况，但下面的代码为我解决了这个问题，希望它也能帮助其他人。我使用了一个线程，在拍摄到照片500ms后延迟关闭和打开相机|type|unstyled|depth|inlineStyleRanges|entityRanges|data|887577|+private+void+start_camera()+{

The camera.startpreview(); answer didn't work for my case but the code below solved that problem for me and hope it helps others too.I used a thread to delay closing and opening of the camera after a photo is captured by 500ms

<pre><code> private void start_camera() {
 try {
 camera = Camera.open();
 // camera.lock();
 } catch (RuntimeException e) {
 Log.e(tag, "init_camera: " + e);
 return;
 }
 Camera.Parameters param = camera.getParameters();
 param = camera.getParameters();
 Camera.Size size = param.getSupportedPreviewSizes().get(0);
 param.setPreviewSize(size.width, size.height);
 camera.setParameters(param);
 try {
 camera.setPreviewDisplay(surfaceHolder);
 camera.startPreview();
 previewRunning = true;
 } catch (Exception e) {
 Log.e(tag, "init_camera: " + e);
 return;
 }}
 private void captureImage() {
 camera.takePicture(shutterCallback,null,jpegCallback);
 Thread restart_preview=new Thread(){public void run(){
 try {
 Thread.sleep(500);
 } catch (InterruptedException e) {
 e.printStackTrace();
 }

 camera.release();
 camera=null;
 start_camera();
 }};
 restart_preview.start();}
</code></pre>

Android camera freezes after taking one photo

图像处理

我正在用相机做一个项目，在拍摄一台相机后，相机冻结了，你必须完成活动并再次调用它来拍摄另一张照片，我如何才能只拍摄1-2秒的照片冻结，然后表面视图再次拥有相机。同样的视频我正在使用媒体录像机，拍摄视频按下停止视频保存和屏幕仍然是活动的，但我不能再次拍摄视频我必须重新启动活动？有人有解决方案吗？
