    <p>I did some testing and I feel that the best way to achieve this is doing a custom <code>Dialog</code>.</p> <p>Here is an example of what I did. This will answer question number 2 but will give you an idea of how to fix question number 1.</p> <pre><code>public class MyProgressDialog extends Dialog { public static MyProgressDialog show(Context context, CharSequence title, CharSequence message) { return show(context, title, message, false); } public static MyProgressDialog show(Context context, CharSequence title, CharSequence message, boolean indeterminate) { return show(context, title, message, indeterminate, false, null); } public static MyProgressDialog show(Context context, CharSequence title, CharSequence message, boolean indeterminate, boolean cancelable) { return show(context, title, message, indeterminate, cancelable, null); } public static MyProgressDialog show(Context context, CharSequence title, CharSequence message, boolean indeterminate, boolean cancelable, OnCancelListener cancelListener) { MyProgressDialog dialog = new MyProgressDialog(context); dialog.setTitle(title); dialog.setCancelable(cancelable); dialog.setOnCancelListener(cancelListener); /* The next line will add the ProgressBar to the dialog. */ dialog.addContentView(new ProgressBar(context), new LayoutParams(LayoutParams.WRAP_CONTENT, LayoutParams.WRAP_CONTENT)); dialog.show(); return dialog; } public MyProgressDialog(Context context) { super(context, R.style.NewDialog); } } </code></pre> <p>All the static methods comes from <a href="http://www.netmite.com/android/mydroid/frameworks/base/core/java/android/app/ProgressDialog.java" rel="noreferrer">this</a> link, nothing strange, but the magic occurs in the constructor. Check that I pass as parameter an style. That style is the following:</p> <pre><code>&lt;?xml version="1.0" encoding="utf-8"?&gt; &lt;resources&gt; &lt;style name="NewDialog" parent="@android:Theme.Dialog"&gt; &lt;item name="android:windowFrame"&gt;@null&lt;/item&gt; &lt;item name="android:windowBackground"&gt;@android:color/transparent&lt;/item&gt; &lt;item name="android:windowIsFloating"&gt;true&lt;/item&gt; &lt;item name="android:windowContentOverlay"&gt;@null&lt;/item&gt; &lt;item name="android:windowTitleStyle"&gt;@null&lt;/item&gt; &lt;item name="android:windowAnimationStyle"&gt;@android:style/Animation.Dialog&lt;/item&gt; &lt;item name="android:windowSoftInputMode"&gt;stateUnspecified|adjustPan&lt;/item&gt; &lt;item name="android:backgroundDimEnabled"&gt;false&lt;/item&gt; &lt;item name="android:background"&gt;@android:color/transparent&lt;/item&gt; &lt;/style&gt; &lt;/resources&gt; </code></pre> <p>The result of this is a <code>ProgressBar</code> rotating in the center of the screen. Without <code>backgroundDim</code> and without the <code>Dialog</code> box.</p>

    2. CO@Macarse: I got an additional question though ;) In case I (or my client.. ;) wants to actually keep the default window frame and background color - how can I still keep the frame (with it's rounded borders, etc. like in my screenshot)? Setting the bg color is obvious, but the parameter android:windowFrame=@null doesn't seem to matter much. If I leave out this line in above code, the default window frame would still not be displayed.; so it seems to have no effect. (so basically all I want is to center the progress indicator properly centered in the default dialog).

    3. CO@Mathias Lin: To answer your question I went through http://developer.android.com/intl/zh-TW/guide/topics/ui/themes.html. Try adding: <item name="android:gravity">center_vertical|center_horizontal</item>

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).
