I am trying to make my layout a bit more uniform. I have a linear layout that looks like this:
<?xml version="1.0" encoding="utf-8"?>
<LinearLayout android:id="@+id/LinearLayout01"
xmlns:android="http://schemas.android.com/apk/res/android"
android:orientation="vertical"
android:layout_width="fill_parent"
android:layout_height="wrap_content">
<LinearLayout
android:orientation="vertical"
android:layout_width="fill_parent"
android:layout_height="wrap_content"
android:layout_weight="1">
<TextView
android:id="@+id/lblQuote"
android:layout_width="fill_parent"
android:layout_height="wrap_content"
android:layout_weight="1"/>
</LinearLayout>
<LinearLayout
android:orientation="horizontal"
android:layout_width="fill_parent"
android:layout_height="wrap_content"
android:layout_weight="1">
<TextView
android:id="@+id/lblLikes"
android:layout_width="fill_parent"
android:layout_height="wrap_content"
android:layout_weight="1"
android:textSize="4pt"
android:text="27"/>
<ImageView
android:id="@+id/imgUp"
android:layout_width="fill_parent"
android:layout_height="wrap_content"
android:layout_weight="1"
android:src="@drawable/thumbsup"/>
<TextView
android:id="@+id/lblBuzzedTitle"
android:layout_width="fill_parent"
android:layout_height="wrap_content"
android:layout_weight="1"
android:textSize="4pt"
android:text="Buzz Level:"/>
<TextView
android:id="@+id/lblShared"
android:layout_width="fill_parent"
android:layout_height="wrap_content"
android:layout_weight="1"
android:textSize="4pt"/>
<TextView
android:id="@+id/lblSaid"
android:layout_width="fill_parent"
android:layout_height="wrap_content"
android:layout_weight="1"
android:textSize="4pt"/>
</LinearLayout>
<LinearLayout
android:orientation="horizontal"
android:layout_width="fill_parent"
android:layout_height="wrap_content"
android:layout_weight="1">
<TextView
android:id="@+id/lblHates"
android:layout_width="fill_parent"
android:layout_height="wrap_content"
android:layout_weight="1"
android:textSize="4pt"
android:text="14"/>
<ImageView
android:id="@+id/imgDown"
android:layout_width="fill_parent"
android:layout_height="wrap_content"
android:layout_weight="1"
android:src="@drawable/thumbsdn"/>
<TextView
android:id="@+id/lblBuzzed"
android:layout_width="fill_parent"
android:layout_height="wrap_content"
android:layout_weight="1"
android:textSize="4pt"/>
<TextView
android:id="@+id/lblDate"
android:layout_width="fill_parent"
android:layout_height="wrap_content"
android:layout_weight="1"
android:textSize="4pt"/>
<TextView
android:id="@+id/lblLocation"
android:layout_width="fill_parent"
android:layout_height="wrap_content"
android:layout_weight="1"
android:textSize="4pt"/>
</LinearLayout>
<LinearLayout
android:orientation="vertical"
android:layout_width="fill_parent"
android:layout_height="wrap_content"
android:layout_weight="1">
<TextView
android:text=" "
android:textSize="1pt"
android:background="#6F7285"
android:layout_width="fill_parent"
android:layout_height="wrap_content"
android:layout_weight="1"/>
</LinearLayout>
</LinearLayout>
So I’ve switched to this:
<?xml version="1.0" encoding="utf-8"?>
<LinearLayout android:id="@+id/LinearLayout01"

android:orientation="vertical"

android:layout_height="fill_parent"
android:weightSum="1">
<TextView
android:id="@+id/lblQuote"
android:layout_width="0dp"
android:layout_height="wrap_content"
android:layout_weight="1"/>
</LinearLayout>
<LinearLayout
android:orientation="horizontal"
android:layout_width="fill_parent"
android:layout_height="fill_parent"
android:weightSum="8">

<LinearLayout

android:layout_height="wrap_content"
android:gravity="center_horizontal"
android:layout_weight="2"
android:textSize="4pt"/>
<TextView
android:id="@+id/lblLocation"
android:layout_width="0dp"
android:layout_height="wrap_content"
android:gravity="center_horizontal"
android:layout_weight="2"
android:textSize="4pt"/>
</LinearLayout>
<LinearLayout
android:orientation="vertical"
android:layout_width="fill_parent"
android:layout_height="fill_parent"
android:weightSum="1">
<TextView
android:text=" "
android:textSize="1pt"
android:background="#6F7285"
android:layout_width="0dp"
android:layout_height="wrap_content"
android:layout_weight="1"/>
</LinearLayout>
</LinearLayout>
Upon doing that my layout goes blank in the emulator. Please advise. I do not want to switch to Relative layout I just want to know what I’m doing wrong with this bit of code. Thanks.

In the second version, your first nested LinearLayout has a layout_height of fill_parent. That pushes everything else down off the screen. Whenever you see yourself using layout_weight when you are also using fill_parent for both width and height, then you know that you are doing something wrong.
What are you trying to accomplish, exactly?
By the way, you don’t need to use weightSum the way you are doing. If you don’t specify it, it will automatically sum up the layout_weight values of all the child views. It’s main use is to distribute only a fraction of the total extra space available.
