    <p>I have two textviews in an activity, defined by xml - both with background color gray. In my app, I set one of the textviews background color to blue. This works as expected.</p> <p><strong>BUT : When I turn the device (rotate), or leave the app and come back again, the other textview is also blue - same color as the one set intentionally...!?</strong></p> <p>When I leave the app and start it again the second textview stays blue. When I stop the app from running (kill) and start it again the second textview is gray. But same problem appears as soon as I rotate the device or start the app the next time.</p> <p>Problem device is running 4.1.1. - same app on 2.3.4 device runs with no problem.</p> <p>SDK Tools 22.0.1, Eclipse Juno Service Release 2 32 bit , Windows 7 64 bit</p> <p><strong>EDIT :</strong> Same problem on SDK Tools 14, Eclipse Indigo SR1 32 bit on Windows 7 32 bit</p> <p>I have no idea what is going on there. It is some kind of undesired MAGIC. Could you please help me?</p> <p><img src="https://i.stack.imgur.com/5wzUL.png" alt="Before"> <img src="https://i.stack.imgur.com/5Cvfg.png" alt="After"></p> <p>Below is the real source code with no modification from the problem project.</p> <p><strong>MainActivity.java:</strong></p> <pre><code>package com.example.test; import android.app.Activity; import android.os.Bundle; import android.widget.TextView; public class MainActivity extends Activity{ @Override protected void onCreate(Bundle savedInstanceState) { super.onCreate(savedInstanceState); setContentView(R.layout.activity_main); TextView tv1 = (TextView) findViewById(R.id.textView1); tv1.setBackgroundColor(0xff33b5e5); } } </code></pre> <p><strong>acitivity_main.xml:</strong></p> <pre><code>&lt;LinearLayout xmlns:android="http://schemas.android.com/apk/res/android" android:layout_width="fill_parent" android:layout_height="fill_parent" android:orientation="vertical" &gt; &lt;TextView android:id="@+id/textView1" android:layout_width="fill_parent" android:layout_height="100dp" android:background="#cccccc" /&gt; &lt;TextView android:id="@+id/textView2" android:layout_width="fill_parent" android:layout_height="100dp" android:layout_marginTop="20dp" android:background="#cccccc" /&gt; &lt;/LinearLayout&gt; </code></pre> <p><strong>AndroidManifest.xml</strong></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.test" android:versionCode="1" android:versionName="1.0" &gt; &lt;uses-sdk android:minSdkVersion="8" android:targetSdkVersion="17" /&gt; &lt;application android:icon="@drawable/ic_launcher" android:label="TextView Test" &gt; &lt;activity android:name="com.example.test.MainActivity" &gt; &lt;intent-filter&gt; &lt;action android:name="android.intent.action.MAIN" /&gt; &lt;category android:name="android.intent.category.LAUNCHER" /&gt; &lt;/intent-filter&gt; &lt;/activity&gt; &lt;/application&gt; &lt;/manifest&gt; </code></pre> <p><strong>EDIT 2:</strong> To make things even stranger: If I change color of textview2 slightly to i.e. #cdcdcd the problem does NOT come. It is only in case both colors (textview1 and textview2) are identical in XML.</p>

    2. COI did that about 100 times already...! :-( The code above is an abstract from my real project. Making that abstract has cost me hours, while constantly refreshing and rebuilding in order to see if the problem is still there.

    3. CO:( I can't see anything wrong with the code above, if you are getting the problem with the posted code that is really weird. Hopefully someone else will help.

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).
