    <p>In a nutshell, add the required API units to the uses clause - the key ones in your case are <code>AndroidApi.Jni.JavaTypes</code>, <code>AndroidApi.Jni.App</code>, and <code>AndroidApi.Jni.GraphicsContentViewText</code>, together with <code>FMX.Helpers.Android</code> for some glue code - and call it pretty much like you might in Java. Java classes are exposed as interface types with an initial J; in practice the Android API uses nested classes quite a lot, and since Delphi doesn't support nested interface types, these become ParentClassName_ChildClassName:</p> <pre><code>var Prefs: JSharedPreferences; Editor: JSharedPreferences_Editor; I: Integer; F: Single; S: string; begin Prefs := SharedActivity.getPreferences(TJActivity.JavaClass.MODE_PRIVATE); Editor := Prefs.edit; Editor.putInt(StringToJString('MyIntKey'), 999); Editor.putFloat(StringToJString('MyFloatKey'), 123.456); Editor.putString(StringToJString('MyStrKey'), StringToJString('This is a test')); Editor.apply; I := Prefs.getInt(StringToJString('MyIntKey'), 0); F := Prefs.getFloat(StringToJString('MyFloatKey'), 0); S := Prefs.getString(StringToJString('MyIntKey'), StringToJString('')); </code></pre> <p>That said, I've recently put out a simple <code>TCustomIniFile</code> descendant that wraps the <code>SharedPreferences</code> API - see here for info:</p> <p><a href="http://delphihaven.wordpress.com/2013/09/12/a-few-xe5-related-bits/" rel="noreferrer">http://delphihaven.wordpress.com/2013/09/12/a-few-xe5-related-bits/</a></p> <p>In mapping the API to <code>TCustomIniFile</code>, one small issue I found is the fact <code>SharedPreferences</code> keys are strongly typed, and there doesn't seem to be a way to find out in advance what type a given key has (keys in <code>TCustomIniFile</code>, in contrast, are weakly typed). Because of this, for reading, I use the <code>getAll</code> method to retreive all keys and values as a <code>Map</code>/<code>JMap</code> (Java dictionary object in other words) and read individual keys from there.</p>

    1. COThat was exactly what I was looking for. Now I can maintain a common interface throughout the various platforms... The MAC unit - is that also for iPhone/iPad, or only for MacOS?

    2. COYes - I've just done a commit that effectively renames TMacPreferencesIniFile to TApplePreferencesIniFile to emphasise the point. Correspondingly, the unit is now CCR.Apple.PrefsIniFile.pas and I've added a generic 'mobile' demo.

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.
