将相机中的图片加载到ImageView中

Question

In my app, I have it so that when the user clicks on the Camera button it takes him to the camera using an intent.

He then takes the picture and it should load it back into the ImageView I have on the same screen as the Camera button.

I think something is wrong with my screen orientation. When I load the camera view it switches to horizontal orientation, and when it closes it switches back to vertical orientation and my whole screen resets back to default.

This is the error I get in logcat:

12-03 20:14:38.440: E/SpannableStringBuilder(15134): SPAN_EXCLUSIVE_EXCLUSIVE spans cannot have a zero length

Any ideas?

EDIT:

Here is what happens:

• I click on the camera button.
• the screen camera view switches to horizontal mode, but I am holding it vertically so it switches to vertical.
• I take the picture in horizontal mode.
• The camera app asks me to save my pic or cancel it in vertical mode.
• I click save.
• My app loads in horizontal mode and places the picture inside the imageView.
• The app then switches back to vertical mode and resets the whole screen.

I put your alls code in, but it isn't helping.

Answer 1

Also the point to be noted is that camera is by default in android works in landscape mode only. So no matter what you screen orientation is, the camera will launch in horizontal mode only. Also as above mentioned do

android:configChanges="orientation"

And handle this in your activity be using the below callback

@Override
public void onConfigurationChanged(Configuration newConfig) {       
    super.onConfigurationChanged(newConfig);

}

Answer 2

The reason that your activity gets reseted is because of the screen orientation change made by the camera intent.

You can put android:configChanges="orientation" inside your activity in the androidManifest.xml

Once you have that, it would not destroy and recreate your activity.

Please see http://developer.android.com/guide/topics/manifest/activity-element.html#config for more details

Answer 3

    setRequestedOrientation(ActivityInfo.SCREEN_ORIENTATION_PORTRAIT);

我所做的只是添加了这行代码，并且效果很好。
