    <p>I faced this strange problem that caused me a lot of headache and trouble.</p> <p>I published an application that is a repository of several books, I decided to use TextView to display the text of each chapter because it fits the requirements and it is fast and easy to be used.</p> <p>The user asked that he could select a text and copy it, I used textIsSelectable = true and everything was fine, next day he called me to report that the text in not changing, you open a chapter and you switch to another chapter but the text remains the same.</p> <p>I thought it might be some logical problem from my side, but after some debugging the problem was in TextView, when I set textIsSelectable = false; everything was fine.</p> <p>To be sure I used a static int that is increased each time the text is displayed, the text remained unchanged.</p> <p>So what is the problem? am I using TextView the wrong way? or it is some bug in the TextView itself?</p> <p>Here's my layout (txtBody is the TextView that causes the problem)</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="match_parent" android:layout_height="match_parent" android:background="@android:color/white"&gt; &lt;ScrollView android:layout_width="match_parent" android:layout_height="match_parent" android:id="@+id/scrollView" android:fillViewport="true" &gt; &lt;LinearLayout android:layout_width="match_parent" android:layout_height="wrap_content" android:orientation="vertical" android:gravity="right"&gt; &lt;TextView android:layout_width="match_parent" android:layout_height="wrap_content" android:text="Title Text" android:id="@+id/txtTitle" android:textSize="24sp" android:padding="5dp" android:gravity="right"/&gt; &lt;TextView android:layout_width="fill_parent" android:layout_height="wrap_content" android:text="Detail Text" android:id="@+id/txtBody" android:background="@android:color/white" android:gravity="right" android:textColor="@android:color/black" android:textSize="16sp" android:padding="5dp" android:enabled="true" android:textIsSelectable="true" android:selectAllOnFocus="false" android:soundEffectsEnabled="true"/&gt; &lt;/LinearLayout&gt; &lt;/ScrollView&gt; &lt;/FrameLayout&gt; </code></pre> <p>I use this code to set the text:</p> <pre><code>String body = MainDataManager.getInstance().getChapterBody(book.getTable(), chapter.getId()); updateTextStyle(); txtTitle.setText(chapter.getTitle()); txtBody.setText(body, TextView.BufferType.SPANNABLE); </code></pre>

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).
