android app development simple messaging app
<p>I use the following <code>main.xml</code> code but I can only see one edit text box</p>

<p>I need help regarding why does this occur? I have tried many times but I cannot see proper edit box and all other components</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;TextView
    android:layout_width="fill_parent"
    android:layout_height="fill_parent"

    android:text="ENTER THE PHONE NUMBER HERE" /&gt;

&lt;EditText 
    android:id="@+id/txtPhoneNo"  
    android:layout_width="fill_parent" 
    android:layout_height="wrap_content"        
    /&gt;
&lt;TextView  
    android:layout_width="fill_parent" 
    android:layout_height="wrap_content"         
    android:text="Message"
    /&gt;     
&lt;EditText 
    android:id="@+id/txtMessage"  
    android:layout_width="fill_parent" 
    android:layout_height="150dp"
    android:gravity="top"         
    /&gt;          
&lt;Button 
    android:id="@+id/btnSendSMS"  
    android:layout_width="fill_parent" 
    android:layout_height="wrap_content"
    android:text="Send SMS"
    /&gt;    
</code></pre>
