  1. POAndroid: Pass an Object into a CustomDialog?
    text
    copied!<p>I've found plenty of simple AlertDialog examples out there, but the tutorials and information I've come across doesn't seem to come close enough to what I need to do to help me solve my problem. I'm stumped.</p> <p>I'm working on a mapping app, and after the user's search results come back I've got a list of the 3 closest results for their query. The results are stored in an array of "Targets" objects, and now I want to pass this array of objects to a dialog box that will let the user click the destination they want to navigate to. Each Targets object has (as instance variables) an index, a latitude, a longitude, a name, an address, and a distance from the current location. At this point, all I really want in the clickable list are distance to the location (rounded to hundredths of a mile): </p> <pre><code>Math.round(target[i].getDistance()*100.0))/100.0 + " Miles to Destination" </code></pre> <p>(maybe that has to be made into one String, I don't know.)</p> <p>and the name of the destination:</p> <pre><code>target[i].getName() </code></pre> <p>Ideally, I'd like these two fields to be printed in nicely aligned columns. I think I need to do this by setting widths in my list layout?</p> <pre><code>&lt;?xml version="1.0" encoding="utf-8"?&gt; &lt;LinearLayout xmlns:android="http://schemas.android.com/apk/res/android" android:layout_width="fill_parent" android:layout_height="fill_parent" android:orientation="horizontal" &gt; &lt;TextView xmlns:android="http://schemas.android.com/apk/res/android" android:id="@+id/distance" android:layout_width="wrap_content" android:layout_height="fill_parent" android:padding="10dp" android:textSize="16sp" &gt; &lt;/TextView&gt; &lt;TextView xmlns:android="http://schemas.android.com/apk/res/android" android:id="@+id/name" android:layout_width="fill_parent" android:layout_height="fill_parent" android:padding="10dp" android:textSize="16sp" &gt; &lt;/TextView&gt; &lt;/LinearLayout&gt; </code></pre> <p>OK, that's as far as I've gotten. How do I construct a dialog that will accept my Targets[] and display choices for a user? (Sorry I don't have any code to show you as a starting point for my dialog. Nothing I've tried works at all so it didn't seem worth it to paste it here.)</p> <p>Thanks!</p>
