Question

Is it possible to add dynamically add Fragments with LayoutParams? I have 2 fragments that I want to put in a RelativeLayout: one should lock to the left. The other should be locked to the right.

You could wrap them each in a layout (such as a LinearLayout), then set its size and position. This answer is regarding a similar problem, and shows how to use a FrameLayout with custom layout parameters to contain a Fragment.

Note that, when using the fragment object in XML, you can use android:layout_* attributes to control its position. Like so:

<LinearLayout
    android:orientation="horizontal"
    ... >

    <fragment
        android:layout_height="wrap_content"
        android:layout_width="0px"
        android:layout_weight="1"
        ... />

    <fragment
        android:layout_height="wrap_content"
        android:layout_width="0px"
        android:layout_weight="1"
        ... />

</LinearLayout>

However, I don’t think it’s possible to apply layout parameters programmatically to Fragments. They’re not ViewGroups, after all.
