Question

I have the following template in my android app. When I use the android:layout_MarginTop=”20dip” does work well, i can see the 20dip space at the top of the layout.

<LinearLayout
android:orientation="horizontal" 
android:layout_width="fill_parent" 
android:layout_height="wrap_content"
android:layout_marginTop="20dip"
style="@style/list_buttom_single"
xmlns:android="http://schemas.android.com/apk/res/android">

<ImageView android:id="@+id/image" android:layout_width="wrap_content" android:layout_height="wrap_content"  />
<LinearLayout android:gravity="center_vertical" android:paddingLeft="10dip" android:orientation="vertical" android:layout_width="wrap_content" android:layout_height="wrap_content" android:layout_weight="1.0">
    <TextView android:text="Login / Register" android:layout_width="wrap_content" android:layout_height="wrap_content" android:id="@+id/title" style="@style/content_page_large_text" />
    <TextView android:text="sample text" android:layout_width="wrap_content" android:layout_height="wrap_content" android:id="@+id/subtitle" android:visibility="visible" style="@style/content_page_small_text" />
</LinearLayout>
<TextView android:layout_width="wrap_content" android:layout_height="wrap_content" android:id="@+id/itemCount" android:visibility="gone" style="@style/content_page_large_count_text" />
<ImageView android:layout_width="wrap_content" android:layout_height="wrap_content" android:id="@+id/chevron" style="@style/list_buttom_chevron" />
</LinearLayout> 

However, when I try to do this programatically using LayoutInflater, i am loosing this 20dip space.

        View notesView = mInflater.inflate(R.layout.list_item_single, null);
    ((TextView) notesView.findViewById(R.id.title)).setText("Notes");
    ((TextView) notesView.findViewById(R.id.subtitle)).setText("102 notes");
    btnContainer.addView(notesView);

Why am I getting two different behavior for the “same” action, the only difference is that one is include uisng xml and the other one is using java.

Many thanks

Because layout parameters are only associated with view if you specify parent view. That’s why you should use another version of inflate():

View notesView = mInflater.inflate(R.layout.list_item_single, btnContainer, false);
...
btnContainer.addView(notesView);
