    <p>I'm building a <code>TextView</code> subclass to change the text that is inserted in the <code>android:text</code>. For instance, I want to capitalize the whole text but, to make sure that it is needed, I need to access the Application instance (I have a boolean that tells if it must or not be capitalized).</p> <p>I implemented this subclass:</p> <pre><code>public class UpperTextView extends TextView { private Context context; public UpperTextView(Context context) { super(context); this.context = context; } public UpperTextView(Context context, AttributeSet attrs, int defStyle) { super(context, attrs, defStyle); this.context = context; } public UpperTextView(Context context, AttributeSet attrs) { super(context, attrs); this.context = context; } @Override public void setText(CharSequence text, BufferType type) { //I get a NullPointerException here since var context is null Context applicationContext = context.getApplicationContext(); if (text != null &amp;&amp; applicationContext instanceof MyApplication &amp;&amp; applicationContext.doUppercase()) { MyApplication myApp = (MyApplication) applicationContext; myApp.getLanguagesController().getLocalizedString(text.toString().toUpperCase()); } super.setText(text, type); } } </code></pre> <p>In the layout, I have it declared like this</p> <pre><code> &lt;my.package.UpperTextView android:id="@+id/foo" android:text="bar"/&gt; </code></pre> <p>I get a NullPointerException when invoking <code>context.getApplicationContext()</code>.</p> <p>Did anyone already came across this?</p>

    1. COyou don't need to keep track of the context, you can call getContext from within a View

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.
