    <p>In my app, I have two imageViews that are the same size and both work fine. However, when I put a picture into each imageView and then try to switch out the top imageView with a different picture, the bottom imageView ends up getting the picture that is supposed to go in the top imageView. I'm not sure why this is. Here is my xml file:</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="match_parent" android:layout_height="match_parent" android:orientation="vertical" &gt; &lt;TextView android:id="@+id/personalizetextView1" android:layout_width="wrap_content" android:layout_height="wrap_content" android:text="@string/customize" android:textSize="30sp" android:gravity="center" android:layout_marginTop="20dip"/&gt; &lt;TextView android:id="@+id/personalizetextviewChangeBackground" android:layout_width="wrap_content" android:layout_height="wrap_content" android:text="@string/customizebackground" android:gravity="center" /&gt; &lt;ImageView android:id="@+id/imageView1" android:layout_width="wrap_content" android:layout_height="wrap_content" android:adjustViewBounds="true" android:maxWidth="100dp" android:maxHeight="100dp" android:scaleType="fitCenter" android:contentDescription="@string/descForBackground" /&gt; &lt;Button android:id="@+id/btnChangeImage" android:layout_width="wrap_content" android:layout_height="wrap_content" android:text="@string/change_background" /&gt; &lt;TextView android:id="@+id/personalizetextviewChangeIcon" android:layout_width="wrap_content" android:layout_height="wrap_content" android:text="@string/change_icon" android:gravity="center" /&gt; &lt;ImageView android:id="@+id/imageView2Icon" android:layout_width="wrap_content" android:layout_height="wrap_content" android:adjustViewBounds="true" android:maxWidth="100dp" android:maxHeight="100dp" android:scaleType="fitCenter" android:contentDescription="@string/descForIcon" /&gt; &lt;Button android:id="@+id/btnChangeImageForIcon" android:layout_width="wrap_content" android:layout_height="wrap_content" android:text="@string/change_icon" /&gt; &lt;/LinearLayout&gt; </code></pre> <p>And then here is my java coding:</p> <pre><code>package com.example.awesomefilebuilderwidget;

    1. CO`image = (ImageView) findViewById(R.id.imageView2Icon);` ??? Why not use two different references?

    3. COInitially, you set image to reference the top image view, `image = (ImageView) findViewById(R.id.imageView1);`. Then you change is to the lower image view. Then you change the image. Why don't you use two references, e.g. imageView1, imageView2.

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).
