&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" android:layout_height="match_parent"&gt; &lt;TextView android:id="@+id/textView1" android:layout_width="wrap_content" android:layout_height="wrap_content" 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:layout_marginTop="36dp" android:layout_toLeftOf="@+id/textView1" android:ems="3" android:inputType="time" /&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; &lt;manifest xmlns:android="http://schemas.android.com/apk/res/android" package="com.example.hush" android:versionCode="1" android:versionName="1.0" &gt;

&lt;activity android:name="com.example.hush.MainActivity" android:label="@string/app_name" &gt; &lt;intent-filter&gt; &lt;action android:name="android.intent.action.MAIN" /&gt; &lt;category android:name="android.intent.category.LAUNCHER" /&gt;

&lt;category android:name="android.intent.category.DEFAULT" /&gt; &lt;/intent-filter&gt; &lt;/activity&gt; &lt;/application&gt; &lt;/manifest&gt; </code></pre>

Guidance
A row detail

Detail views are divided into sections. All the information in the data section comes from columns in the selected row. The other sections display data from other, related rows.

Related data can be related in a to-one or a to-many fashion. Captions of data related in a to-many fashion link to a list view showing a filtered view of the table.

Try moving around until you find a non-empty to-many entry and click on the label to get to one. You can move back to the root by clicking on the database name in the header.

SQuiL has stopped working due to an internal error.

If you are curious you may find further information in the browser console, which is accessible through the devtools (F12).
