当我开始拍照，然后在其表面进来对面 [英] when i start camera then its surface comes in just opposite

问题描述

我的code表面创作是：

 公共无效surfaceCreated（SurfaceHolder为arg0）{
        // TODO自动生成方法存根
        如果（相机== NULL）{
            尝试{
                Log.e（相机开始，相机开始）;
                相机= android.hardware.Camera.open（）;
                Camera.Parameters参数= camera.getParameters（）;
                //最终名单＆LT;串GT; 。coloreffects = camera.getParameters（）getSupportedColorEffects（）;
                mParameters.set（旋转，ANTIBANDING_60HZ）;
                parameters.setFocusMode（Camera.Parameters.EFFECT_SEPIA）;
                parameters.getFocusMode（）;                mParameters.set（旋转，90）;
                parameters.setFocusMode（android.intent.extra.focus）;
                意向意图=新意图（android.intent.extra.focus）;
                startActivityForResult（意向，0）;                camera.setParameters（参数）;
                Log.e（摄像机运行，相机runnng）;            }赶上（例外五）{
                // TODO自动生成catch块
                e.printStackTrace（）;
            }
             }
 

解决方案

使用此code。而变化AVD 2.2版

  @覆盖
        公共无效surfaceCreated（SurfaceHolder持有人）{
         相机= Camera.open（）;         尝试{
                camera.set previewDisplay（支架）;
                Camera.Parameters参数= camera.getParameters（）;
                parameters.setPictureFormat（PixelFormat.JPEG）;
                parameters.set（方向，肖像）;
                camera.setDisplayOrientation（90）;
                parameters.setRotation（90）;
                camera.setParameters（参数）;
            }
            赶上（IOException异常除外）{
                camera.release（）;
            }
        }
 

my code for surface creation is:

public void surfaceCreated(SurfaceHolder arg0){
        // TODO Auto-generated method stub


        if (camera == null) {
            try {
                Log.e("camera starting","camera starting");
                camera = android.hardware.Camera.open();
                Camera.Parameters parameters = camera.getParameters();
                //final List<String> coloreffects = camera.getParameters().getSupportedColorEffects();
                mParameters.set("rotation","ANTIBANDING_60HZ");
                parameters.setFocusMode(Camera.Parameters.EFFECT_SEPIA);
                parameters.getFocusMode();

                mParameters.set("rotation",90);
                parameters.setFocusMode("android.intent.extra.focus");
                Intent intent = new Intent("android.intent.extra.focus");
                startActivityForResult(intent, 0);

                camera.setParameters(parameters);
                Log.e("camera running","camera runnng");

            } catch (Exception e) {
                // TODO Auto-generated catch block
                e.printStackTrace();
            }
             }

解决方案

Use this code. And change avd version 2.2

        @Override
        public void surfaceCreated(SurfaceHolder holder) {
         camera = Camera.open();

         try {
                camera.setPreviewDisplay(holder);
                Camera.Parameters parameters = camera.getParameters();
                parameters.setPictureFormat(PixelFormat.JPEG);
                parameters.set("orientation", "portrait");
                camera.setDisplayOrientation(90); 
                parameters.setRotation(90);
                camera.setParameters(parameters);
            }
            catch (IOException exception) {
                camera.release();
            }
        }
