             android:text="Edit" /&gt;
  &lt;/RelativeLayout&gt;
  </code></pre>
  
  <p>and the second Xml to which im trying to reach in another activity:</p>
  
  <pre><code>&lt;?xml version="1.0" encoding="utf-8"?&gt;
  &lt;RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android"
      android:layout_width="match_parent"

      &lt;TextView
          android:id="@+id/textView1"

          android:layout_alignParentTop="true"
          android:layout_centerHorizontal="true"
          android:layout_marginTop="20dp"
          android:textSize="40sp"
          android:text="Monday" /&gt;
  
      &lt;EditText
          android:id="@+id/editText1"
          android:layout_width="wrap_content"
          android:layout_height="wrap_content"
          android:layout_below="@+id/textView1"

          android:ems="3"
          android:inputType="time" /&gt;
  
      &lt;EditText

          android:inputType="time" &gt;
          &lt;requestFocus /&gt;
      &lt;/EditText&gt;
  
        &lt;Spinner

          android:prompt="@string/profile"
          android:entries="@array/profileSelector"/&gt;
  &lt;/RelativeLayout&gt;
  </code></pre>
  
  <p>Finally the code that supports both:</p>
  
  <pre><code>package com.example.hush;
  
  import android.os.Bundle;
  import android.app.Activity;
  import android.content.Intent;
  import android.view.Menu;
  import android.widget.Button;
  import android.view.View.OnClickListener;
  
  public class MainActivity extends Activity {
        Intent clickedDay;
      @Override
      protected void onCreate(Bundle savedInstanceState) {
          super.onCreate(savedInstanceState);
          setContentView(R.layout.mainlayout);
          Button mondayEdit=(Button)findViewById(R.id.button1);
      }
  
      public void mondayintent()
      {
          clickedDay= new Intent(this,Monday.class);
          startActivity(clickedDay);
      }
  
      @Override
      public boolean onCreateOptionsMenu(Menu menu) {
          // Inflate the menu; this adds items to the action bar if it is present.
          getMenuInflater().inflate(R.menu.main, menu);
          return true;
      }
  }
  </code></pre>
  
  <p>second activity code:</p>
  
  <pre><code>package com.example.hush;
  
  import android.app.Activity;
  import android.os.Bundle;
  import android.widget.Button;
  
  public class Monday extends Activity{           
  
      @Override
      public void onCreate(Bundle savedInstanceState){
          super.onCreate(savedInstanceState);
          setContentView(R.layout.monday);
      }
  }
  </code></pre>
  
  <p>Below I have added my android-manifest.xml</p>
  
  <pre><code>&lt;?xml version="1.0" encoding="utf-8"?&gt;
