In my app, there is a tabbed activity with three `fragments`. The first fragment has a form to create a new task, the second fragment has the list of all the saved tasks, and the third fragment will show the comments on a task when selected from the list in the second fragment. The third `fragment` is also supposed to act like a chat activity which posts comments when you type them in and tap the send button. The XML layout of this third `fragment` is as follows:

```
<?xml version="1.0" encoding="utf-8"?>
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
xmlns:tools="http://schemas.android.com/tools"
android:layout_width="match_parent"
android:layout_height="match_parent"
android:background="@android:color/darker_gray"
android:orientation="vertical"
tools:context="com.example.ishita.assigntasks.CommentsFragment">

<TextView
    android:id="@+id/frag_task_details"
    android:layout_width="match_parent"
    android:layout_height="wrap_content"
    android:background="#dd55ff"
    android:padding="10dp" />

<ListView
    android:id="@+id/frag_comment_list"
    android:layout_width="match_parent"
    android:layout_height="0dp"
    android:layout_weight="1"
    android:transcriptMode="normal" />

<LinearLayout
    android:layout_width="match_parent"
    android:layout_height="wrap_content"
    android:orientation="horizontal"
    android:background="@android:color/white">

    <EditText
        android:id="@+id/frag_msg_edit"
        android:layout_width="0dp"
        android:layout_height="wrap_content"
        android:inputType="textMultiLine"
        android:layout_weight="1" />

    <ImageButton
        android:id="@+id/frag_send_btn"
        style="?android:attr/buttonStyleSmall"
        android:layout_width="wrap_content"
        android:layout_height="wrap_content"
        android:layout_weight="0"
        android:background="@android:color/background_light"
        android:contentDescription="@string/send_btn"
        android:src="@android:drawable/ic_menu_send" />

</LinearLayout>

</LinearLayout>

```

As you can see, there is a `TextView` and a `ListView` and below that is another `LinearLayout`. Here is how it should look (the purple bar is the `TextView`):

And here is how it actually looks:

The `TextView` shows up above the `ListView`, but the `LinearLayout` does not. It is there, though. If I do `android:layout_marginBottom="20dp"` on the outermost `LinearLayout`, it does show up, but the `ActionBar` scrolls up and overlaps with the notification bar so that the title on the `ActionBar` and the notifications on the notification bar are both visible simultaneously and neither is legible.

I searched a lot and this seemed a common issue, but none of the solutions helped me. Believe me, I tried everything I could find. I tried wrapping the whole thing in a `FrameLayout`, using a `RelativeLayout` in place of the outermost `LinearLayout`, using two `LinearLayout`s--one to wrap the `TextView` and the `ListView` and the other to wrap the `EditText` and the `ImageButton`, etc., but nothing was able to show the bottom `LinearLayout` below the `ListView`. I even tried to set focus on the `EditText` when the fragment launches so that the keyboard would show and I can type, but even that doesn't help.

**Note:** On the other hand, if I use the exact same layout on an `activity`, the bottom `LinearLayout` displays exactly as it should.

I am unable to find the bug. Please help!
