    <p>I have a custom widget in a library project (Spinnerbutton) that I want to use in an application project. The custom widget contains a TextView and I want to pass a style to that TextView from my app project. </p> <p>This is my attrs.xml (in the library project): </p> <pre><code>&lt;?xml version="1.0" encoding="utf-8"?&gt; &lt;resources&gt; &lt;declare-styleable name="Spinnerbutton"&gt; &lt;attr name="myTextAppearence" format="reference" /&gt; &lt;/declare-styleable&gt; &lt;/resources&gt; </code></pre> <p>And the app's layout: </p> <pre><code>&lt;RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android" xmlns:tools="http://schemas.android.com/tools" xmlns:custom="http://schemas.android.com/apk/lib/com.example.spinnerbuttonlib" android:id="@+id/root" android:layout_width="match_parent" android:layout_height="match_parent" &gt; &lt;com.example.spinnerbuttonlib.spinnerbutton.Spinnerbutton android:id="@+id/sbp" android:layout_width="match_parent" android:layout_height="wrap_content" android:layout_marginTop="8dp" custom:myTextAppearence="@style/SmallTextGray" /&gt; &lt;/RelativeLayout&gt; </code></pre> <p>Here's how I try to read my custom attribute in the Spinnerbutton class: </p> <pre><code>public Spinnerbutton(Context context, AttributeSet attrs) { super(context, attrs); this.context = context; TypedArray a = context.obtainStyledAttributes(attrs, R.styleable.Spinnerbutton); int textStyleId = a.getResourceId( R.styleable.Spinnerbutton_myTextAppearence, -1); a.recycle(); } </code></pre> <p>textStyleId always return -1, so the value is not passed from my layout to the class. </p> <p>What's wrong here?</p>

    3. COlooks all right. I tried it without library project works. I could use the spinner button in myproject. But i guess you need to customize the style by customizing the parent style.

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).
