相机应用修改成横屏后，出现的常见问题解决方法...
首先要注意的是，展锐平台的相机应用DreamCamera2是基于竖屏手机设备开发的，未作横屏适配，非必要不建议把相机应用改为横屏，修改成横屏会导致mode的UI错位、部分功能无法使用、预览方向和成像方向不匹配等等许多问题。
根据不同项目需求可能会出现不同的问题，本faq旨在介绍如何将相机应用改为横屏，以及提供一些常见问题的解决方案。以Andorid10 8541E为例
修改成横屏
修改文件vendor\sprd\platform\packages\apps\DreamCamera2\Androidmanifest.xml，把android:screenOrientation的值"portrait"统统替换为"landscape"
修改ui角度，修改相机左下角缩略图旋转角度
修改文件vendor\sprd\platform\packages\apps\DreamCamera2\src\com\android\camera\widget\RoundedThumbnailView.java
@Override
public void setOrientation(int degree, boolean animation) {
mEnableAnimation = animation;
// make sure in the range of
degree = degree >= 0 ? degree % 360 : degree % 360 + 360;
+ degree += 90;
修改左滑显示的modelist列表图标角度
修改文件：vendor\sprd\platform\packages\apps\DreamCamera2\src\com\android\camera\ui\ModeSelectorItem.java
@Override
public void setOrientation(int degree, boolean animation) {
Log.e(TAG, " setOrientation mCurrentDegree = " + degree);
mEnableAnimation = animation;
// make sure in the range of
degree = degree >= 0 ? degree % 360 : degree % 360 + 360;
+ degree += 90;
if (degree == mTargetDegree)
修改相机顶部ui图标旋转角度
修改文件vendor\sprd\platform\packages\apps\DreamCamera2\src\com\android\camera\ui\RotateImageButton.java
@Override
public void setOrientation(int degree, boolean animation) {
mEnableAnimation = animation;
// make sure in the range of
degree = degree >= 0 ? degree % 360 : degree % 360 + 360;
+ degree = degree + 90;
if (degree == mTargetDegree)
return;
修改相机拍照按钮旋转角度
vendor\sprd\platform\packages\apps\DreamCamera2\src\com\android\camera\ui\RotateImageView.java
public void setOrientation(int degree, boolean animation) {
mEnableAnimation = animation;
// make sure in the range of
degree = degree >= 0 ? degree % 360 : degree % 360 + 360;
+ degree = degree + 90;
修改预览角度
camera api1中可以通过setCameraDisplayOrientation()方法修改预览方向，但是camera api2没有旋转预览的相关接口，只能修改sensor_config.xml文件中对应camera id的<Orientation>角度值，可分别尝试使用0/90/180/270这四个值，具体按项目实际情况来定。
修改成像角度,旋转拍照照片角度
Camera APP中，照片角度可通过 ANDROID_JPEG_ORIENTATION tag设置。
DreamCamera2 APP的图片角度可以通过以下 mJpegRotation 来修改。
src/com/android/camera/PhotoModule.java
@Override
public boolean capture() {
.................................
boolean isFrontCamera = info.isFacingFront();
mJpegRotation = CameraUtil.getImageRotation(sensorOrientation,
deviceOrientation, isFrontCamera); ////mJpegRotation为图片旋转的角度 可根据实际需求增加 90 180 270
Log.i(TAG, " sensorOrientation = " + sensorOrientation
旋转录像视频角度
Camera APP中，录像角度的修改通过 setOrientationHint(int degrees) 接口实现。
DreamCamera2 APP的录像角度可以通过以下rotation来完成
src/com/android/camera/VideoModule.java
private class VideoRecordStartTask extends AsyncTask<Void, Void, Void> {
.................................
@Override
protected void onPostExecute(Void result) {
.................................
int rotation = CameraUtil.getImageRotation(sensorOrientation,
deviceOrientation, isCameraFrontFacing()); ///录像旋转角度rotation可根据实际需求增加 90 180 270
/**
* SPRD: Add for bug 585183, 3d video recoding @{
* Original Code
*
mMediaRecorder.setOrientationHint();
*/
mMediaRecorder.setOrientationHint(getRecorderOrientationHint(rotation));//设置录像角度
屏蔽无法适配横屏的功能
横屏之后目前无法适配的功能有全景、滤镜等，可以参考如下修改去除：
修改文件vendor\sprd\platform\packages\apps\DreamCamera2\src\com\android\camera\util\CameraUtil.java
//去除全景
public static boolean isWideAngleEnable() {
- return 0 < wideAngleVersion && isBackCameraEnable;
+ //return 0 < wideAngleVersion && isBackCameraEnable;
+ return false;
}
//去除滤镜
public static boolean isUseSprdFilter() {
- return (mFilterVersion == 2);
+ //return (mFilterVersion == 2);
+ return false;
}
//去除慢动作
public static boolean isSlowMotionEnabled() {
- return isSlowMotionEnabled && isBackCameraEnable();
+ //return isSlowMotionEnabled && isBackCameraEnable();
+ return false;
}
//去除有声照片
public static boolean isVoicePhotoEnable() {
- return isVoicePhotoEnabled;
+ //return isVoicePhotoEnabled;
+ return false;
}
//去除二维码
public static boolean isQrCodeEnabled(){
- return isQrCodeEnabled && isBackCameraEnable;
+ //return isQrCodeEnabled && isBackCameraEnable;
+ return false;
}
