take a screenshot of a nested RelativeLayout

I have my layout xml in this form:

<?xml version="1.0" encoding="utf-8"?>
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
    android:layout_width="fill_parent"
    android:layout_height="fill_parent"
    xmlns:tools="http://schemas.android.com/tools"
    android:orientation="vertical">

    <RelativeLayout xmlns:android="http://schemas.android.com/apk/
    res/android"
        android:layout_width="fill_parent"
        android:layout_height="fill_parent"
        android:paddingBottom="@dimen/activity_vertical_margin"
        android:paddingLeft="@dimen/activity_horizontal_margin"
        android:paddingRight="@dimen/activity_horizontal_margin"
        android:paddingTop="@dimen/activity_vertical_margin"
        android:background="#3fb399"
        tools:context="com.sparrowred.cardsender.customizeCard">

        <RelativeLayout xmlns:android="http://schemas.android.com/apk/
        res/android"
            android:id="@+id/relativeViewPrint"
            android:layout_width="fill_parent"
            android:layout_height="fill_parent"
            xmlns:tools="http://schemas.android.com/tools"
            android:orientation="vertical"
            android:weightSum="1"
            android:layout_above="@+id/button_send"
            android:layout_alignParentStart="true"
            android:layout_below="@+id/add_button">

            <TextView
                android:layout_width="match_parent"
                android:layout_height="180dp"
                android:id="@+id/textView_wish_card"
                android:textAlignment="center"
                android:textSize="20sp"
                android:layout_weight="0.06"
                android:layout_alignParentBottom="true"
                android:layout_alignParentStart="true" />

            <TextView
                android:layout_width="149dp"
                android:layout_height="112dp"
                android:background="@drawable/image0"
                android:layout_gravity="center"
                android:alpha="0.4"
                android:id="@+id/textView_wish_cardBack"
                android:layout_weight="0.75"
                android:layout_alignTop="@+id/textView_wish_card"
                android:layout_alignParentStart="true"
                android:layout_alignParentBottom="true"
                android:layout_alignParentEnd="true" />

        </RelativeLayout>

    </RelativeLayout>

</LinearLayout>

The two textviews are overlapping. The one holds an image (with transparency) and the other one, a color and a text (this is why I have them on a single RelativeLayout and overlapping). I want to get a screenshot of this RelativeLayout. I used this method but it doesn't work. Any help please?

private void ScreenShot2(){
    Display display = getWindowManager().getDefaultDisplay();
    Point size = new Point();
    display.getSize(size);
    RTLout.measure(View.MeasureSpec.makeMeasureSpec(0,
    size.x), View.MeasureSpec.makeMeasureSpec(0, size.y));
    RTLout.layout(0, 0, RTLout.getWidth(), RTLout.getHeight());
    RTLout.setDrawingCacheEnabled(true);
    RTLout.setDrawingCacheQuality(View.DRAWING_CACHE_QUALITY_HIGH);
    Bitmap b = Bitmap.createBitmap(RTLout.getDrawingCache());
    RTLout.setDrawingCacheEnabled(false);
    if(b !=null) {
        try {
            String extr = Environment.getExternalStorageDirectory().
            getAbsolutePath().toString() + File.separator + "Pictures" 
            + File.separator + "Screenshots";
            File dir = new File(extr);
            if (!dir.exists())
                dir.mkdirs();
            String fileName =
            new SimpleDateFormat("yyyyMMddhhmm'_report.jpg'").
            format(new Date());
            File myPath = new File(dir, fileName);
            FileOutputStream fos = null;
            try {
                fos = new FileOutputStream(myPath);
                b.compress(Bitmap.CompressFormat.JPEG, 100, fos);
                fos.flush();
                fos.close();
                MediaStore.Images.Media.insertImage(getContentResolver(),
                b, "Screen", "screen");
            } catch (FileNotFoundException e) {
                e.printStackTrace();
            } catch (Exception e) {
                e.printStackTrace();
            }
        }catch (Exception e) {
            e.printStackTrace();
        }
    }
}

It seems you don't call buildDrawingCache method on your layout before adding it to the bitmap by getDrawingCache.

Do something like this (this code is without the other options you used):

RelativeLayout RTLout= (RelativeLayout )findViewById(R.id.relativeViewPrint);
RTLout.setDrawingCacheEnabled(true);
RTLout.buildDrawingCache();
Bitmap bm = view.getDrawingCache();
