先看界面布局文件
[html] view plaincopy
- <?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" >
- <EditText
- android:id="@+id/edit"
- android:layout_width="fill_parent"
- android:layout_height="wrap_content" />
- <EditText
- android:id="@+id/edit1"
- android:layout_width="fill_parent"
- android:layout_height="wrap_content"
- android:password="true" />
- <RelativeLayout
- android:layout_width="fill_parent"
- android:layout_height="wrap_content" >
- <android.inputmethodservice.KeyboardView
- android:id="@+id/keyboard_view"
- android:layout_width="fill_parent"
- android:layout_height="wrap_content"
- android:layout_alignParentBottom="true"
- android:focusable="true"
- android:focusableInTouchMode="true"
- android:background="@color/lightblack"
- android:keyBackground="@drawable/btn_keyboard_key"
- android:keyTextColor="@color/white"
- android:visibility="gone" />
- </RelativeLayout>
- </LinearLayout>
通过布局文件可以看出界面上有两个输入框,其中一个是密码输入框,界面上还有一个隐藏的键盘控件。
在res下新建xml文件夹,在xml文件夹中新建qwerty.xml和symbols.xml文件. qwerty.xml 是字母键盘布局,symbols.xml 是数字键盘布局,内如如下
qwerty.xml内容
