How to make 4x1 size widget on Android homescreen?

问题

I have difficulties developing 4x1 widget for Android.

This is the appprovider

<?xml version="1.0" encoding="utf-8"?> <appwidget-provider
    xmlns:android="http://schemas.android.com/apk/res/android"
    android:minWidth="294dp"
    android:minHeight="72dp"
    android:initialLayout="@layout/main" />

And here is the main.xml

<?xml version="1.0" encoding="utf-8"?>
<LinearLayout
    xmlns:android="http://schemas.android.com/apk/res/android"
    android:layout_width="320dp"
    android:layout_height="100dp"
    android:gravity="center_vertical|center_horizontal"
    android:orientation="horizontal"> 
//content goes here
</LinearLayout>

I could see the widget but the size is 4x2. I confuse why I cannot have 4x1 widget size?

Thanks

I don't think it's a newbie mistake.. I've had an appWidget that was 1x1 cell in size. I set it to 72dp x 72dp, and it was working fine.. But it seems like Google changed the widget dimension sizing formula from

(cells * 74) - 2

to

(cells * 70) - 30

So now the default size of my widget has to be 40dp x 40dp..

In ICS it must be showing 4x2.

To correct this make a folder in 'res' name 'xml-v14':

Define your widget appwidget-provider with same xml name here. just change minHeight to 40dp. This will correct the error.

Hope this help you.
