如何使用前置摄像头的三星Galaxy S

问题描述

我试了几个答案我已经在网络中，如：

I've tried several answer I've found across the web, such as:

Camera.Parameters parameters = mCamera.getParameters();
parameters.set("camera-id", 2);
mCamera.setParameters(parameters);

或

mMediaRecorder.setVideoSource(2);

不过，这是行不通的。我还设置权限在manifest文件：

But it doesn't work. I've also set permissions on the manifest file:

<uses-permission android:name="android.permission.CAMERA" />
<uses-feature android:name="android.hardware.camera" />

难道我错过了什么？我搜索计算器，我知道这已被问过，但似乎对此没有证实的解决方案，任何形式的帮助将是AP preciated。

Am i missing out on something? I've searched StackOverflow and I know this has been asked before but there seem to be no confirmed solution on this, any kind of help would be appreciated.

注：我在2.1平台上使用的Galaxy S

Note: I'm using Galaxy S on the 2.1 platform

推荐答案

一些试验和错误后，无论如何，我想通了如何做到这一点：

Anyway after a few trials and error, I figured it out how to do it:

Camera.Parameters parameters = mCamera.getParameters();
parameters.set("camera-id", 2);
parameters.setPreviewSize(640, 480); // or (800,480) this is supported front camera preview size @ Samsung Galaxy S
mCamera.setParameters(parameters);

或者，如果你需要使用它的MediaRecorder：

Or, if you need to use it with MediaRecorder:

MediaRecorder mMediaRecorder = new MediaRecorder();
Camera mCamera = Camere.open();
Camera.Parameters parameters = mCamera.getParameters();
parameters.set("camera-id", 2);
parameters.setPreviewSize(640, 480); // or (800,480)
mCamera.setParameters(parameters);
mCamera.unlock(); // unlock, to give other process to access it otherwise it can't be used later
mMediaRecorder.setCamera(mCamera);
// continue with mMediaRecorder standard routines here

如果你需要有一个更小的preVIEW大小，您可以设置/缩小你的SurfaceView大小，而不是。

If you need to have a smaller preview size, you could set/scale down your SurfaceView size instead.
