图像保存方向错误 [英] Image saved with wrong orientation

问题描述

我用这code：

<一个href="https://github.com/commonsguy/cw-advandroid/blob/master/Camera/Picture/src/com/commonsware/android/picture/PictureDemo.java" rel="nofollow">https://github.com/commonsguy/cw-advandroid/blob/master/Camera/Picture/src/com/commonsware/android/picture/PictureDemo.java

凡清单，活动方向设置为风景

所以，它就像让用户只需要在横向模式的图片，如果图片正在通过保持设备在纵向模式下，保存的图像是这样的：

So, its like allowing user to take picture only in Landscape mode, and if the picture is taking by holding the device in portrait mode, the image saved is like this:

90度旋转的图像。

在寻找一个解决方案，我发现这一点：

After searching for a solution, I found this:

Android的 - 摄像头preVIEW横盘

其中，解决的办法是：

在 surfaceChanged（）检查

Display display = ((WindowManager)getSystemService(WINDOW_SERVICE)).getDefaultDisplay();
display.getRotation();

和修改相机的displayOrientation 相应。

camera.setDisplayOrientation(90);

但不管多少次，我旋转设备， surfaceChanged（）永远不会被调用。

我甚至尝试去除方向=横向在的Manifest.xml ，但那么preVIEW本身是横盘显示（可能是因为默认 android.view.SurfaceView 应该是在风景模式？）。

I even tried removing orientation="Landscape" in the Manifest.xml, but then the preview itself is shown sideways(may be because default android.view.SurfaceView is supposed to be in Landscape mode?).

推荐答案

试试这个。

public void surfaceCreated(SurfaceHolder holder) {
    try {
        camera = Camera.open();
        camParam = camera.getParameters();
        Camera.Parameters params = camera.getParameters();
        String currentversion = android.os.Build.VERSION.SDK;
        Log.d("System out", "currentVersion " + currentversion);
        int currentInt = android.os.Build.VERSION.SDK_INT;
        Log.d("System out", "currentVersion " + currentInt);

        if (getResources().getConfiguration().orientation == Configuration.ORIENTATION_PORTRAIT) {
            if (currentInt != 7) {
                camera.setDisplayOrientation(90);
            } else {
                Log.d("System out", "Portrait " + currentInt);

                params.setRotation(90);

                /*
                 * params.set("orientation", "portrait");
                 * params.set("rotation",90);
                 */
                camera.setParameters(params);
            }
        }
        if (getResources().getConfiguration().orientation == Configuration.ORIENTATION_LANDSCAPE) {
            // camera.setDisplayOrientation(0);
            if (currentInt != 7) {
                camera.setDisplayOrientation(0);
            } else {
                Log.d("System out", "Landscape " + currentInt);
                params.set("orientation", "landscape");
                params.set("rotation", 90);
                camera.setParameters(params);
            }
        }
        camera.setPreviewDisplay(holder);
        camera.startPreview();
    } catch (IOException e) {
        Log.d("CAMERA", e.getMessage());
    }
}
