    <p>So right now I have a main.xml</p> <pre><code>&lt;?xml version="1.0" encoding="utf-8"?&gt; &lt;LinearLayout xmlns:android="http://schemas.android.com/apk/res/android" xmlns:myapp="http://schemas.android.com/apk/res/com.b" android:orientation="vertical" android:layout_width="fill_parent" android:layout_height="fill_parent" android:background="@color/background_color" android:textColorPrimaryInverse="#E97C03" &gt; &lt;LinearLayout android:orientation="horizontal" android:layout_width="wrap_content" android:layout_height="wrap_content" android:background="@color/background_color" android:textColorPrimaryInverse="#E97C03" &gt; &lt;ImageView android:id="@+id/header_image" android:layout_width="wrap_content" android:layout_height="wrap_content" android:src="@drawable/logo" android:layout_gravity="left" android:background="@color/seperator_bg_color" /&gt; &lt;ImageView android:id="@+id/build_image" android:layout_width="wrap_content" android:layout_height="wrap_content" android:src="@drawable/ic_camera" android:layout_gravity="left" /&gt; &lt;ImageView android:id="@+id/saved_image" android:layout_width="wrap_content" android:layout_height="wrap_content" android:src="@drawable/ic_details" /&gt; &lt;ImageView android:id="@+id/settings_image" android:layout_width="wrap_content" android:layout_height="wrap_content" android:src="@drawable/ic_menu_upload" /&gt; &lt;/LinearLayout&gt; &lt;TextView android:id="@+id/seperator_text" android:layout_width="fill_parent" android:layout_height="wrap_content" android:padding="1dip" android:background="@color/seperator_bg_color" android:textColor="@color/seperator_text_color" android:textStyle="bold" android:text="@string/header_build" android:textColorPrimaryInverse="#E97C03" /&gt; &lt;!-- &lt;TextView --&gt; &lt;!-- android:id="@+id/selection" --&gt; &lt;!-- android:layout_width="fill_parent" --&gt; &lt;!-- android:layout_height="wrap_content" --&gt; &lt;!-- /&gt;--&gt; &lt;ListView android:id="@android:id/list" android:layout_width="fill_parent" android:layout_height="fill_parent" android:drawSelectorOnTop="false" android:textColorPrimaryInverse="#E97C03" /&gt; &lt;/LinearLayout&gt; </code></pre> <p>Now, of course everything that uses the main.xml will have a header at the top(everything that is contained in the second, horizontal, LinearLayout.</p> <p>In all of those views however, I have links with header_image, saved_image, build_image, etc that will take the user to a specific view. The problem is that if I make a change, I have to go and edit every single Activity that has those links.</p> <p>Is there a way I can create an external class that will just contain information like this:</p> <pre><code>build =(ImageView)findViewById(R.id.build_image); build.setOnClickListener(buildClick); saved =(ImageView)findViewById(R.id.saved_image); saved.setOnClickListener(savedClick); prefs =(ImageView)findViewById(R.id.settings_image); prefs.setOnClickListener(prefsClick); </code></pre> <p>instead of having that code in every single Activity?</p> <p>EDIT: Essentially, I want to re-use my main.xml as my header for all activities, however where I set setOnClickListener I dont want to have to set those in every activity because if I change/add to the header, I have to dig through all the activities and change those.</p> <p>So I want to take the code above and put it in a separate class. That way, in an activity, I call that class, and it will set those values for the header. Or set onClick settings in the XML, if that is possible.</p>

    1. COCan you clarify what you mean by "all of those views... have links with .." Are you talking about separate xmls or just view elements within this main.xml? Are you trying to re-use main.xml as your "header" for all activities to use?

    2. COYeah, I want to re-use my main.xml as my header for all activities, however where I set setOnClickListener I dont want to have to set those in every activity because if I change/add to the header, I have to dig through all the activities and change those.

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.

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