it should still fix some issue For setting image size create a layoutParams , If your imageView parent is a LinearLayout so you should do this :
code :
LinearLayout.LayoutParams lp = imageView.getLayoutParams();
lp.width = lastImageWidth;
lp.height = lastImageHeight;
imageView.setLayoutParams(lp);

it should still fix some issue Hi can any one tell how we can change the xml layout to java code. I need to show the grid view inside the tab view . For that I need to implement these attributes in Java code rather than xml .Please reply , say you have the grid view accessed:
code :
final GridView gw = [...];
// This line applies to a GridView that you've just created
gv.setLayoutParams(new LayoutParams(LayoutParams.FILL_PARENT, LayoutParams.FILL_PARENT));
// The next two lines are for a GridView that you already have displayed
gv.getLayoutParams().width = LayoutParams.FILL_PARENT;
gv.getLayoutParams().height = LayoutParams.FILL_PARENT;

gv.setNumColumns(GridView.AUTO_FIT);
gv.setVerticalSpacing(convertFromDp(10));
gv.setHorizontalSpacing(convertFromDp(10));
gv.setColumnWidth(convertFromDp(90));
gv.setStretchMode(GridView.STRETCH_COLUMN_WIDTH);
gv.setGravity(Gravity.CENTER);

should help you out I suggest ViewFlipper inside RelativeLayout of your include statements. Try like this:
code :
<ViewFlipper xmlns:android="http://schemas.android.com/apk/res/android"
    android:id="@+id/vf"
    android:layout_width="fill_parent"
    android:layout_height="wrap_content" >

    <include android:id="@+id/include1" layout="@layout/ikinci" />
    <include android:id="@+id/map" layout="@layout/third_layout" />

</ViewFlipper>
ViewFlipper vf = (ViewFlipper)findViewById(R.id.vf);
button.setOnClickListener(new View.OnClickListener() {

            @Override
            public void onClick(View v) {
                // TODO Auto-generated method stub
                vf.setDisplayedChild(1);
            }
        });

hope this fix your issue I have a frame layout and want to change the background image/color depending on the current state of an array. I can change text depending on the array so understand how to do that but can't find a way to reference the layout. , Pass layout via GridPagerAdapter constructor and save in a variable.
code :
private static final class GridPagerAdapter extends FragmentGridPagerAdapter {


    private final FrameLayout li;
    String[][] mData;

    private GridPagerAdapter(FragmentManager fm, String[][] data, FrameLayout li)
    {
        super(fm);
        mData = data;
        this.li = li;
    }

    //... stuff
}
@Override
protected void onCreate(Bundle savedInstanceState)
{
    super.onCreate(savedInstanceState);
    setContentView(R.layout.activity_main);
    FrameLayout li =(FrameLayout) findViewById(R.id.framelayout);

    final DotsPageIndicator mPageIndicator;
    final GridViewPager mViewPager;

    final String[][] data =
            {
            { "Row 0, Col 0", "Row 0, Col 1", "Row 0, Col 2", "Row 0, Col 3" },
            { "Row 1, Col 0", "Row 1, Col 1", "Row 1, Col 2" },
            { "Row 2, Col 0", "Row 2, Col 1", "Row 2, Col 2" }
    };

    // Get UI references
    mPageIndicator = (DotsPageIndicator) findViewById(R.id.page_indicator);
    mViewPager = (GridViewPager) findViewById(R.id.pager);

    // Assigns an adapter to provide the content for this pager
    mViewPager.setAdapter(new GridPagerAdapter(getFragmentManager(), data, li));
    mPageIndicator.setPager(mViewPager);
}

like below fixes the issue Instead of RecyclerView, add the items in a LinearLayout. You can also set position where to add the new item in the LinearLayout.
I would suggest you do instead is:
