Question

I had an application of timer and my app should always be in LandScape mode. I am getting width and Height of my main layout in code. In manifest, I had used:

     <activity android:name=".MActivity"
                      android:label="@string/app_name"
                      android:screenOrientation="landscape"
android:theme="@android:style/Theme.NoTitleBar"
                android:configChanges="keyboardHidden|orientation">

And in activity :

layout = (LinearLayout)findViewById(R.id.Rishikesh);
        ViewTreeObserver vto = layout.getViewTreeObserver();
        vto.addOnGlobalLayoutListener(new OnGlobalLayoutListener() {

            public void onGlobalLayout() {
                int finalHeight, finalWidth;
                finalHeight = layout.getMeasuredHeight();
                finalWidth = layout.getMeasuredWidth();
                Log.w("*************", "OnGlobalLayoutListener/ Footer height :"+layout.getHeight()+" Width :"+layout.getWidth());


            }
        });

It gives height and width in landscape mode. But when i lock my phone, It gives height and width in portrait mode. What I am doing wrong I don't know. I am working on ANdroid 2.1. Can anyone help me solving this.

Solution

The issue is that your application is not in foreground and other applications may request to allow portrait or only portrait.

You receive current global layout - which may be portrait. Probably you receive onPause() before screen is locked and onResume() when your application is back in foreground - if you don't want to get layout when not in background, simply use a bool to store if you're the foreground app.

OTHER TIPS

check after removing "android:configChanges="keyboardHidden|orientation"
