Question

所以，我一直在引用这个：http://developer.android.com/reference/android/hardware/Camera.html

我使用LibGDX这就是为什么你会看到一些不同之处，我也将mCamera改为androidCamera以便于阅读。

这是我的代码：

package com.fmeg.tapdat.android.camera;

import java.io.IOException;

import android.hardware.Camera;
import android.view.SurfaceHolder;
import android.view.SurfaceView;

import com.fmeg.tapdat.android.AndroidLauncher;
import com.fmeg.tapdat.camera.CameraInterface;

public class AndroidCamera extends SurfaceView implements
        SurfaceHolder.Callback, CameraInterface {

    private AndroidLauncher application;

    private SurfaceHolder mHolder;

    private Camera androidCamera;

    public AndroidCamera(AndroidLauncher _application) {
        super(_application.getContext());
        this.application = _application;
        mHolder = getHolder();
        mHolder.addCallback(this);
        mHolder.setType(SurfaceHolder.SURFACE_TYPE_PUSH_BUFFERS);
        surfaceCreated(mHolder);
    }

    @Override
    public void showCamera(boolean show) {
        androidCamera.startPreview();
    }

    /**
     * Organized by call order
     */
    @Override
    public void surfaceCreated(SurfaceHolder holder) {
        androidCamera = Camera.open();
        try {
            androidCamera.setPreviewDisplay(mHolder);
        } catch (Exception e) {
        }
    }

    @Override
    public void surfaceChanged(SurfaceHolder holder, int format, int width,
            int height) {
        Camera.Parameters params = androidCamera.getParameters();
        params.setPreviewSize(width, height);
        androidCamera.setParameters(params);
    }

    @Override
    public void surfaceDestroyed(SurfaceHolder holder) {
        androidCamera.stopPreview();
        androidCamera = null;
    }


}

我有一个名为CameraInterface的接口，代码如下：

package com.fmeg.tapdat.camera;

public interface CameraInterface {
    public void showCamera(boolean show);
}

在我的主类（android项目）中，我的代码看起来像这样

[代码]

public class AndroidLauncher extends AndroidApplication {
    @Override
    protected void onCreate (Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        AndroidApplicationConfiguration config = new AndroidApplicationConfiguration();
        AndroidCamera cam = new AndroidCamera(this);
        initialize(new TapdatGame(cam), config);
    }

}

并在我的主要课程（核心项目）

package com.fmeg.tapdat;

import com.badlogic.gdx.ApplicationAdapter;
import com.badlogic.gdx.Gdx;
import com.badlogic.gdx.graphics.GL20;
import com.fmeg.tapdat.camera.CameraInterface;

public class TapdatGame extends ApplicationAdapter {

    private CameraInterface camera;

    public TapdatGame(CameraInterface cameraInterface) {
        this.camera = cameraInterface;
    }

    @Override
    public void create () {
        camera.showCamera(true);
    }

    @Override
    public void render () {
        Gdx.gl.glClear(GL20.GL_COLOR_BUFFER_BIT);
    }

    public CameraInterface getCamera() { 
        return camera;
    }

}

请帮助我实现此功能，当前实现会调用相机故障

Tag(Camera) - Error 1001

让相机在应用程序上工作
