輸入法手勢識別(Gestures Builder)

1. 開啟Android模擬器>開啟Gestures Builder

2.選擇Add gesture

3.輸入Name > 輸入手勢辨別圖形 > Done

4. 產生gestures檔案,路徑在/storage/sdcard/gestures,匯出到你要的路徑,在專案res之下建立       raw資料夾,把匯出的檔匯入到raw資料夾

以下為程式碼

1. activity_main.xml

<?xml version="1.0" encoding="utf-8"?>
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
    android:layout_width="fill_parent"
    android:layout_height="fill_parent"
    android:orientation="vertical" >

    <TextView
        android:layout_width="fill_parent"
        android:layout_height="wrap_content"
        android:text="" />

    <android.gesture.GestureOverlayView
        android:id="@+id/gestures"
        android:layout_width="fill_parent"
        android:layout_height="0dip"
        android:layout_weight="1.0"
        android:gestureColor="#00ff00"/>


</LinearLayout>
