android如何做自己的手寫IME

1、xml

<LinearLayout        android:id="@+id/gesture_main_writepad_ll"        android:layout_width="fill_parent"        android:layout_height="330dip"        android:layout_alignParentBottom="true"        android:background="#262626"        android:orientation="vertical"        android:visibility="gone" >        <Gallery            android:id="@+id/gesture_main_writepad_glly"            android:layout_width="fill_parent"            android:layout_height="60dip"            android:spacing="3dip" />        <TextView             android:layout_width="fill_parent"            android:layout_height="1px"            android:background="@color/auto_color"            />        <RelativeLayout            android:layout_width="fill_parent"            android:layout_height="230dip" >            <LinearLayout                android:id="@+id/search_no_input"                android:layout_width="fill_parent"                android:layout_height="230dip"                android:background="@android:color/transparent"                android:gravity="center" >                <TextView                    android:layout_width="fill_parent"                    android:layout_height="fill_parent"                    android:gravity="center"                    android:background="@android:color/transparent" />            </LinearLayout>            <android.gesture.GestureOverlayView                android:id="@+id/gesture_main_writepad_gs"                android:layout_width="fill_parent"                android:layout_height="230dip"                android:fadeOffset="100000"                android:gestureColor="#6B8E23"                android:gestureStrokeType="multiple"                android:gestureStrokeWidth="5" />        </RelativeLayout>        <LinearLayout            android:layout_width="fill_parent"            android:layout_height="40dip"            android:orientation="horizontal" >            <Button                android:id="@+id/gesture_main_hide_btn"                android:layout_width="fill_parent"                android:layout_height="fill_parent"                android:layout_marginLeft="3dip"                android:layout_weight="2"                android:background="#838B83"                android:text="hide" />            <Button                android:id="@+id/gesture_main_space_btn"                android:layout_width="fill_parent"                android:layout_height="fill_parent"                android:layout_marginLeft="3dip"                android:layout_weight="1"                android:background="#838B83"                android:text="space" />            <Button                android:id="@+id/gesture_main_del_btn"                android:layout_width="fill_parent"                android:layout_height="fill_parent"                android:layout_marginLeft="3dip"                android:layout_weight="2"                android:background="#838B83"                android:text="del" />        </LinearLayout>    </LinearLayout>
