當設備旋轉時,我試圖旋轉我的相機,iv嘗試了幾種方法,但似乎沒有一種方法適用於所有設備。Android相機旋轉通用
//這個工作對我的Nexus 5,但不是我的三星Galaxy Tab上
public void surfaceChanged(SurfaceHolder holder, int format, int width, int height)
{
if (mHolder.getSurface() == null)
{
return;
}
try
{
mCamera.stopPreview();
Camera.Parameters parameters = mCamera.getParameters();
parameters.set("orientation", "landscape");
int rotation = ((WindowManager) getContext().getSystemService(Context.WINDOW_SERVICE)).getDefaultDisplay().getRotation();
int orientation = getContext().getResources().getConfiguration().orientation;
if (rotation == Surface.ROTATION_0) {
if (orientation == Configuration.ORIENTATION_LANDSCAPE) {
mCamera.setDisplayOrientation(0);
} else {
mCamera.setDisplayOrientation(90);
}
}
else if (rotation == Surface.ROTATION_90) {
if (orientation == Configuration.ORIENTATION_PORTRAIT) {
mCamera.setDisplayOrientation(270);
}
}
else if (rotation == Surface.ROTATION_180) {
if (orientation == Configuration.ORIENTATION_LANDSCAPE) {
mCamera.setDisplayOrientation(180);
}
}
else if (rotation == Surface.ROTATION_270) {
if (orientation == Configuration.ORIENTATION_PORTRAIT) {
mCamera.setDisplayOrientation(90);
}
}
mCamera.setPreviewDisplay(holder);
mCamera.startPreview();
}
catch (Exception e) {
}
}
//和我想這,這是文檔的一部分,它在我的Nexus 5不工作:
public static void setCameraDisplayOrientation(Activity activity,
int cameraId, android.hardware.Camera camera) {
android.hardware.Camera.CameraInfo info =
new android.hardware.Camera.CameraInfo();
android.hardware.Camera.getCameraInfo(cameraId, info);
int rotation = activity.getWindowManager().getDefaultDisplay()
.getRotation();
int degrees = 0;
switch (rotation) {
case Surface.ROTATION_0: degrees = 0; break;
case Surface.ROTATION_90: degrees = 90; break;
case Surface.ROTATION_180: degrees = 180; break;
case Surface.ROTATION_270: degrees = 270; break;
}
int result;
if (info.facing == Camera.CameraInfo.CAMERA_FACING_FRONT) {
result = (info.orientation + degrees) % 360;
result = (360 - result) % 360; // compensate the mirror
} else { // back-facing
result = (info.orientation - degrees + 360) % 360;
}
camera.setDisplayOrientation(result);
}
有人對所有設備都有工作解決方案嗎?
你是什麼意思,「它不工作」?你輸出的圖像是否被旋轉? – simekadam
相機旋轉不正確。對不起,如果我不清楚我的問題。 –
