java bridge - center a button

[Kevin Moran]

How do you center a button (or an image for that matter) using Java bridge? I mean, you could create a horizontal arrangement, subtract the button width from the width of the Form, then divide that by 2 and put that value as margins on both sides but that seems really hacky to me. Is there a better way?

Thanks,
Kevin

For Now:
      HorizontalArrangement hr = new HorizontalArrangement(this, LENGTH_FILL_PARENT);
      new Label(hr, "", LENGTH_FILL_PARENT, COLOR_NONE);
      Button buttonStart = new Button(this, "I'm centered");
      new Label(hr, "", LENGTH_FILL_PARENT, COLOR_NONE);

Hossein, I think you mentioned to me that someone created some Java Bridge samples that allow you to create ui objects in the Android xml fashion. Is that with a different library? 

Kevin, I'm not suggesting we switch on this as far as building the tutorials apps, just want to know if its something that should be explored.

Kevin,
Functionality added into bridge. Also, added functionality of a Splash screen.

Forgot the link to show you how to setup splash:

Excellent, thanks Hossein.

David,

Bridge does not force to use of bridge components. For example, you can create a linear layout with a text label in there like the following:
setContentView(R.layout.mylaout);
TextView tv = (TextView) findViewById(R.id.myTextView);

where firstTextView is defined in your layout xml like:
<?xml version="1.0" encoding="utf-8"?>
<LinearLayout
        xmlns:android="http://schemas.android.com/apk/res/android"
        android:orientation="vertical"
        android:layout_width="fill_parent"
        android:layout_height="fill_parent"
        android:gravity="center_horizontal">
    <TextView
            android:id="@+id/myTextView"
            android:layout_width="fill_parent"
            android:layout_height="wrap_content"
            android:gravity="center_horizontal"
            android:text="Hello"
            android:textSize="42sp" />
</LinearLayout>

Hi David,

  To answer your question, yes there is a java bridge library out there which allows the use of the GLE in Eclipse. I put out the Alternate Java Bridge library, which has become an Eclipse plugin. It can be used just like the original java bridge (coding all UI components), or you can use the GLE to drop them in (and "link" to them in code). It makes it much easier designing the UI, especially if you are trying to support multiple screen sizes. Note that for the AltBridge, resource files go in the standard SDK places (images into the drawable folders, sounds into the raw folder).

The plugin makes starting a new project trivial. It includes a new project wizard to automatically copy over the jar file, add it to the build path, and setup the original Form.
