保存的图像方向错误

我正在使用这段代码：

https://github.com/commonsguy/cw-advandroid/blob/master/Camera/Picture/src/com/commonsware/android/picture/PictureDemo.java https://github.com/commonsguy/cw-advandroid/blob/master/Camera/Picture/src/com/commonsware/android/picture/PictureDemo.java

在哪里Manifest, Activity Orientation被设定为景观.

所以，就像只允许用户在横向模式下拍照，如果是在纵向模式下手持设备拍照，则保存的图像如下所示：

90 度旋转的图像。

在寻找解决方案后，我发现了这个：

Android - 相机预览是横向的 https://stackoverflow.com/questions/3841122/android-camera-preview-is-sideways

解决方案是：

in surfaceChanged()检查

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

并改变相机显示方向因此。

camera.setDisplayOrientation(90);

但无论我旋转设备多少次，surfaceChanged()永远不会被叫到。

我什至尝试删除orientation="Landscape" in the 清单.xml，但是预览本身是横向显示的（可能是因为默认android.view.SurfaceView应该是在横向模式?).

尝试这个。

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());
    }
}
