Question

I defined dynamically all GUI components.When the Cntrl+F11 is first pressed the layout updates correctly to from portrait to landscape. But when I press Cntrl+F11 again, layout remains in its “landscape” look. How can I update it for “portrait” look again? The source code:

//Main Layout ll
LinearLayout ll ;
ll.setOrientation (LinearLayout.VERTICAL);
ll.setLayoutParams(new ViewGroup.LayoutParams(LayoutParams.FILL_PARENT,LayoutParams.FILL_PARENT));

//Inner layout ll2 is inside of the main layout ll
LinearLayout ll2 = new LinearLayout (this);
ll2.setWeight(1.0f);

LinearLayout.LayoutParams lp = new LinearLayout.LayoutParams(LayoutParams.FILL_PARENT,LayoutParams.FILL_PARENT);
lp.weight = 0.25f;

//Button b is inside of the inner layout ll2
Button b = new Button (this);
b.setLayoutParams(lp);
ll2.addView (b);

ll.addView(ll2);

I tried this solution (from this site):
I added function

    public void onConfigurationChanged(Configuration newConfig) {
      super.onConfigurationChanged(newConfig);
      setContentView(ll);
    }

and set I in AndroidManifest

android:configChanges="keyboardHidden|orientation"

but it stiil doesn’t work.Thanks.

Answer 1

use this in xml file

android:orientatoin=”portrait “

it is also possible to write in onCreate() method also

You Also specify in ANDROID_MANIFEST like this

 <activity android:name=".activityName" android:screenOrientation="landscape"></activity>
