我想在这里为Android手机开发一个主题代码，我在网站上找到了一些但是它不起作用。
我在/res/values/styles.xml中的XML代码。
<resources>
<!-- Base application theme is the default theme. -->
<style name="Theme" parent="android:Theme">
</style>
<!-- Variation on our application theme that has a translucent
background. -->
<style name="Theme.Translucent">
<item name="android:windowBackground">@drawable/translucent_background</item>
<item name="android:windowNoTitle">true</item>
<item name="android:colorForeground">#fff</item>
</style>
<!-- Variation on our application theme that has a transparent
background; this example completely removes the background,
allowing the activity to decide how to composite. -->
<style name="Theme.Transparent">
<item name="android:windowBackground">@drawable/transparent_background</item>
<item name="android:windowNoTitle">true</item>
<item name="android:colorForeground">#fff</item>
</style>
<style name="TextAppearance.Theme.PlainText" parent="android:TextAppearance.Theme">
<item name="android:textStyle">normal</item>
</style>
</resources>
WidgetActivity：
public class WidgetActivity extends Activity {
@Override protected void onCreate(Bundle bundle) {
super.onCreate(bundle);
Log.i(Global.TAG2, "sub-Activity WidgetActivity being creation: start");
setTheme(R.style.Theme_Translucent);
setContentView(Panel2Builder.createWidgetPanel(this));
Log.i(Global.TAG2, "sub-Activity WidgetActivity being creation: end");
}
}//end class WidgetActivity
这不符合我的预期。 任何人都有想法为Android的主题工作，并通过开发来实现。
