问题描述

我开发了一个安卓应用程序.因为我使用了前置摄像头功能.它工作正常，但我需要自动捕获.即没有单击快门按钮的声音，我想捕获照片代码..

I have developed an android application. In that i have used front facing camera functionality. Its working fine but I need to auto capture. i.e. without click shutter button sound, I want to capture photocode..

我的相机活动代码是

 private Camera openFrontFacingCameraGingerbread() { 
    int cameraCount = 0; 
    Camera cam = null; 
    Camera.CameraInfo cameraInfo = new Camera.CameraInfo(); 
    cameraCount = Camera.getNumberOfCameras(); 
    for ( int camIdx = 0; camIdx < cameraCount; camIdx++ ) { 
        Camera.getCameraInfo( camIdx, cameraInfo ); 
        if ( cameraInfo.facing == Camera.CameraInfo.CAMERA_FACING_FRONT  ) { 
            try { 
                cam = Camera.open( camIdx ); 
            } catch (RuntimeException e) { 
                Log.i("Camera failed to open: ",e.getLocalizedMessage()); 
            } 
        } 
    } 
    return cam; 
} 

提前谢谢..

推荐答案

按照 Android 开发者 参考页面.不需要有快门按钮".如果您不想在屏幕上显示图像，可以创建一个虚拟 SurfaceHolder，例如

Follow the steps outlined in the Android Developer reference pages. There's no requirement to have a 'shutter button'. You can create a dummy SurfaceHolder if you don't want to show the image on the screen, e.g.

SurfaceView surface = new SurfaceView(context);
cam.setPreviewDisplay(surface.getHolder());
