title: Two tableLayout inside a linearLayout
body: <p>I would place two table layout inside a <code>Linearlayout</code>. But with my code, I can see only one table. That's the code:</p>
  
  <pre><code>&lt;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"
  tools:context=".MainActivity" &gt;
  
  &lt;TableLayout
      android:layout_width="match_parent"
      android:layout_height="match_parent"
      android:gravity="center"
      android:stretchColumns="1" &gt;
  
      &lt;TableRow
          android:layout_width="match_parent"
          android:layout_height="match_parent"
          android:gravity="center" &gt;
  
          &lt;TextView
              android:id="@+text_view/tw_nome"
              android:text="@string/tw_nome" /&gt;
  
          &lt;EditText
              android:id="@+edit_text/et_nome"
              android:hint="@string/et_nome"
              android:imeOptions="actionNext"
              android:singleLine="true" /&gt;
      &lt;/TableRow&gt;
  
      &lt;TableRow
          android:layout_width="match_parent"
          android:layout_height="match_parent"
          android:gravity="center" &gt;
  
          &lt;TextView
              android:id="@+text_view/tw_cognome"
              android:text="@string/tw_cognome" /&gt;
  
          &lt;EditText
              android:id="@+edit_text/et_cognome"
              android:hint="@string/et_cognome"
              android:imeOptions="actionDone"
              android:singleLine="true" /&gt;
      &lt;/TableRow&gt;
  &lt;/TableLayout&gt;
  
  &lt;TableLayout
      android:layout_width="match_parent"
      android:layout_height="match_parent"
      android:gravity="center" &gt;
  
      &lt;TableRow
          android:layout_width="match_parent"
          android:layout_height="match_parent"
          android:gravity="center" &gt;
  
          &lt;TextView
              android:id="@+text_view/tw_sesso"
              android:text="@string/tw_sesso" /&gt;
  
          &lt;RadioGroup
              android:id="@+radio_group/rg"
              android:orientation="horizontal" &gt;
  
              &lt;RadioButton
                  android:id="@+radio_button/button_m"
                  android:text="@string/button_m" /&gt;
  
              &lt;RadioButton
                  android:id="@+radio_button/button_f"
                  android:text="@string/button_f" /&gt;
          &lt;/RadioGroup&gt;
      &lt;/TableRow&gt;
  
      &lt;TableRow
          android:layout_width="wrap_content"
          android:layout_height="wrap_content"
          android:gravity="center" &gt;
  
          &lt;Button
              android:id="@+button/button_salva"
              android:layout_width="wrap_content"
              android:layout_height="wrap_content"
              android:text="@string/button_salva" /&gt;
  
          &lt;Button
              android:id="@+button/button_annulla"

      &lt;/TableRow&gt;
