I'm using the master/detail flow of android and I'm trying to detect the screen orientation in order to make the master part smaller in portrait mode but I'm having some difficulties, I wrote this method :
@Override
    public void onConfigurationChanged(Configuration newConfig) {
        // TODO Auto-generated method stub
        super.onConfigurationChanged(newConfig);
        if (newConfig.orientation == Configuration.ORIENTATION_PORTRAIT){
            setContentView(R.layout.activity_analyse_list);
            LinearLayout layout = (LinearLayout) findViewById(R.id.mastermenu);
            layout.setLayoutParams(new LinearLayout.LayoutParams(0, LayoutParams.MATCH_PARENT, (float) 0.5));
        }
    }
And i put it in the ListActivity which is the first and main activity but nothing happen when I flip the tablet, I tried to use Log.d to see if the onConfigurationChanged is called on the rotation but nothing on the logcat.
