Android Gesture gesture creation and use example

in the Android1.6 simulator is preloaded with a program called gestures Builder, this program is to let you create your own gestures (gestures Builder's source code in the SDK asked samples inside there, interested to see)

Copy the above four files to your project directory,

Run the project file above the emulator and create some gesture files on the emulator, for example:

The created gesture will be saved to the/mnt/sdcard/gestures, and a new test gesture project file will be built and the gestures file copied to the raw file in the Res directory,

Then configure the XML file with the following XML configuration:

1<relativelayout xmlns:android= "Http://schemas.android.com/apk/res/android"2Xmlns:tools= "Http://schemas.android.com/tools"3Android:layout_width= "Match_parent"4android:layout_height= "Match_parent"5android:paddingbottom= "@dimen/activity_vertical_margin"6android:paddingleft= "@dimen/activity_horizontal_margin"7android:paddingright= "@dimen/activity_horizontal_margin"8android:paddingtop= "@dimen/activity_vertical_margin"9tools:context= "Com.xunfang.gesture.MainActivity" >Ten  One<Android.gesture.GestureOverlayView AAndroid:id= "@+id/gv" -Android:layout_width= "Match_parent" -android:layout_height= "Match_parent" theAndroid:background= "#000000" -Android:gesturestrokewidth= "10" -Android:gesturecolor= "#ff0000" -/> +     -  +</RelativeLayout>

Gestureoverlayview: A transparent overlay for gesture input that can be overridden on top of other controls, or can contain other controls.
Android:gesturestroketype defines the type of strokes (defined as gestures)
Android:gesturestrokewidth the width of the stroke when drawing gestures

Activity file content is as follows

This is used to dial the phone interface, be sure to add permissions, as shown in

After that, the code is played and can be tested.

I enter a 6

And then it bounced out. Indicates that the validation was successful.
