  1. POImplementing a dynamic Android layout
    text
    copied!<p>I am implementing an Android layout that acts as an instruction manual of sorts. So basically I have several pages that the user can flip through. Let's say I implemented it like this:</p> <pre><code>&lt;?xml version="1.0" encoding="utf-8"?&gt; &lt;FrameLayout xmlns:android="http://schemas.android.com/apk/res/android" android:layout_width="fill_parent" android:layout_height="fill_parent"&gt; &lt;LinearLayout android:id="@+id/page_1" android:layout_width="match_parent" android:layout_height="match_parent" &gt; &lt;!-- Put stuff for page 1 --&gt; &lt;/LinearLayout&gt; &lt;LinearLayout android:id="@+id/page_2" android:layout_width="match_parent" android:layout_height="match_parent" android:visibility="INVISIBLE"&gt; &lt;!-- Put stuff for page 2 --&gt; &lt;/LinearLayout&gt; &lt;LinearLayout android:id="@+id/page_3" android:layout_width="match_parent" android:layout_height="match_parent" android:visibility="INVISIBLE"&gt; &lt;!-- Put stuff for page 3 --&gt; &lt;/LinearLayout&gt; &lt;!-- ... --&gt; &lt;LinearLayout android:id="@+id/page_N" android:layout_width="match_parent" android:layout_height="match_parent" android:visibility="INVISIBLE"&gt; &lt;!-- Put stuff for page N --&gt; &lt;/LinearLayout&gt; &lt;/FrameLayout&gt; </code></pre> <p>Basically how I would simulate the "page flipping effect" (perhaps with animation) is to make the current page invisible and make the new page visible. However, this implementation has some problems:</p> <ol> <li>Since I'm basically loading all the pages at the same time, the Activity holding this layout will use up a lot of heap, especially if there's background images involved.</li> <li>The above problem is going to get worse as I expand the manual.</li> <li>I've considered splitting the pages into separate activities, but that seems a bit excessive and too troublesome.</li> </ol> <p>I was thinking if there's a way to dynamically load a page from an XML file during run time. As in, would it be possible to inflate a particular layout whenever the user demands it? Or if anyone has a better implementation that I haven't though of, please tell me!</p>
