Check orientation on Android phone

Question

How can I check if the Android phone is in Landscape or Portrait?

Answer 1

Old post I know. Whatever the orientation may be or is swapped etc. I designed this function that is used to set the device in the right orientation without the need to know how the portrait and landscape features are organised on the device.

   private void initActivityScreenOrientPortrait()
    {
        // Avoid screen rotations (use the manifests android:screenOrientation setting)
        // Set this to nosensor or potrait

        // Set window fullscreen
        this.activity.getWindow().setFlags(WindowManager.LayoutParams.FLAG_FULLSCREEN, WindowManager.LayoutParams.FLAG_FULLSCREEN);

        DisplayMetrics metrics = new DisplayMetrics();
        this.activity.getWindowManager().getDefaultDisplay().getMetrics(metrics);

         // Test if it is VISUAL in portrait mode by simply checking it's size
        boolean bIsVisualPortrait = ( metrics.heightPixels >= metrics.widthPixels ); 

        if( !bIsVisualPortrait )
        { 
            // Swap the orientation to match the VISUAL portrait mode
            if( this.activity.getResources().getConfiguration().orientation == Configuration.ORIENTATION_PORTRAIT )
             { this.activity.setRequestedOrientation(ActivityInfo.SCREEN_ORIENTATION_LANDSCAPE); }
            else { this.activity.setRequestedOrientation(ActivityInfo.SCREEN_ORIENTATION_PORTRAIT ); }
        }
        else { this.activity.setRequestedOrientation(ActivityInfo.SCREEN_ORIENTATION_NOSENSOR); }

    }

Works like a charm!

Here is code snippet demo how to get screen orientation was recommend by hackbod and Martijn:

❶ Trigger when change Orientation:

@Override
public void onConfigurationChanged(Configuration newConfig) {
    super.onConfigurationChanged(newConfig);
        int nCurrentOrientation = _getScreenOrientation();
    _doSomeThingWhenChangeOrientation(nCurrentOrientation);
}

❷ Get current orientation as hackbod recommend:

private int _getScreenOrientation(){    
    return getResources().getConfiguration().orientation;
}

❸There are alternative solution for get current screen orientation ❷ follow Martijn solution:

private int _getScreenOrientation(){
        Display display = ((WindowManager) getSystemService(WINDOW_SERVICE)).getDefaultDisplay();
        return display.getOrientation();
}

★Note: I was try both implement ❷ & ❸, but on RealDevice (NexusOne SDK 2.3) Orientation it returns the wrong orientation.

★So i recommend to used solution ❷ to get Screen orientation which have more advantage: clearly, simple and work like a charm.

★Check carefully return of orientation to ensure correct as our expected (May be have limited depend on physical devices specification)

Hope it help,

Answer 3

Some time has passed since most of these answers have been posted and some use now deprecated methods and constants.

I've updated Jarek's code to not use these methods and constants anymore:

protected int getScreenOrientation()
{
    Display getOrient = getWindowManager().getDefaultDisplay();
    Point size = new Point();

    getOrient.getSize(size);

    int orientation;
    if (size.x < size.y)
    {
        orientation = Configuration.ORIENTATION_PORTRAIT;
    }
    else
    {
        orientation = Configuration.ORIENTATION_LANDSCAPE;
    }
    return orientation;
}

Note that the mode Configuration.ORIENTATION_SQUARE isn't supported anymore.

I found this to be reliable on all devices I've tested it on in contrast to the method suggesting the usage of getResources().getConfiguration().orientation

Answer 4

The Android SDK can tell you this just fine:

getResources().getConfiguration().orientation

Answer 5

There is one more way of doing it:

public int getOrientation()
{
    if(getResources().getDisplayMetrics().widthPixels>getResources().getDisplayMetrics().heightPixels)
    { 
        Toast t = Toast.makeText(this,"LANDSCAPE",Toast.LENGTH_SHORT);
        t.show();
        return 1;
    }
    else
    {
        Toast t = Toast.makeText(this,"PORTRAIT",Toast.LENGTH_SHORT);
        t.show();
        return 2;
    }       
}

Answer 6

Use getResources().getConfiguration().orientation it's the right way.

You just have to watch out for different types of landscapes, the landscape that the device normally uses and the other.

Still don't understand how to manage that.
