title: layout_weight: Text is not displayed
body: <p>I was trying to make an interface that allows horizontal texts to be equally space, using layout_weight for responsiveness</p>
  
  <p>So, I tried the code below</p>
  
  <pre><code>&lt;LinearLayout
  xmlns:android="http://schemas.android.com/apk/res/android"
  android:orientation="vertical"
  android:layout_width="match_parent"
  android:layout_height="match_parent"
  android:gravity="center_vertical"
  android:background="@android:color/darker_gray"&gt;
  
  &lt;TextView
      android:gravity="center"
      android:text="Guest List"
      android:layout_width="match_parent"
      android:layout_height="wrap_content"
      android:textSize="24sp"
      android:background="@android:color/holo_blue_bright"/&gt;
  
  &lt;LinearLayout
  xmlns:android="http://schemas.android.com/apk/res/android"
  android:orientation="horizontal"
  android:layout_width="match_parent"
  android:layout_height="wrap_content"
  android:background="@android:color/white"&gt;
      &lt;TextView
          android:text="Kunal"
          android:layout_width="0dp"
          android:layout_height="wrap_content"
          android:layout_weight="1"
          android:textSize="24sp"/&gt;
  
  
      &lt;TextView
          android:text="Darling"
          android:layout_width="0dp"
          android:layout_height="wrap_content"
          android:layout_weight="1"
          android:textSize="24sp"/&gt;
  
      &lt;TextView
          android:text="Shocker"
          android:layout_width="0dp"
          android:layout_height="wrap_content"
          android:layout_weight="1"
          android:textSize="24sp"/&gt;
  &lt;/LinearLayout&gt;
  </code></pre>
  
  <p></p>
  
  <p>However, all the texts disappear. 
  So, could anyone please kindly explain to me what happened and how to fix this problem?</p>
