    <p>I'm trying to create a View with rounded corners (and a background color of choice) that I can reuse with different background colors; hard to explain, so here's my code:</p> <p><em>/app/src/com/packagename/whatever/CustomDrawableView.java</em></p> <pre><code> package com.packagename.whatever; import android.content.Context; import android.content.res.TypedArray; import android.graphics.Canvas; import android.graphics.drawable.PaintDrawable; import android.util.AttributeSet; import android.view.View; public class CustomDrawableView extends View { private PaintDrawable mDrawable; int radius; private void init(AttributeSet attrs) { TypedArray a = getContext().obtainStyledAttributes(attrs,R.styleable.RoundedRect); radius = a.getInteger(R.styleable.RoundedRect_radius, 0); } public CustomDrawableView(Context context, AttributeSet attrs) { super(context, attrs); init(attrs); mDrawable = new PaintDrawable(); } protected void onDraw(Canvas canvas) { mDrawable.setCornerRadius(radius); mDrawable.draw(canvas); } } </code></pre> <p>Here's the XML to display the custom component: <em>/app/res/layout/test.xml</em></p> <pre><code>&lt;?xml version="1.0" encoding="utf-8"?&gt; &lt;LinearLayout xmlns:android="http://schemas.android.com/apk/res/android" xmlns:ny="http://schemas.android.com/apk/res/com.packagename.whatever" android:layout_width="fill_parent" android:layout_height="fill_parent" android:background="#ffffff" android:padding="10dp"&gt; &lt;com.packagename.whatever.CustomDrawableView android:id="@+id/custom" android:layout_width="200dp" android:layout_height="200dp" android:background="#b80010" ny:radius="50" /&gt; &lt;/LinearLayout&gt; </code></pre> <p>I'm wanting the red box to have 50px rounded corners, but as you'll see, it does not:</p> <p><img src="https://i.stack.imgur.com/7BSGR.png" alt="Red box without rounded corners"></p> <p>The idea is that I could easily change the background color in the XML and automatically have a nice View with rounded corners, without having to create multiple drawables.</p> <p>Thanks for the help!</p>

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.
