android自定义金额输入键盘_Android自定义软键盘的实现
先看界面布局文件
android:layout_width="fill_parent"
android:layout_height="fill_parent"
android:orientation="vertical" >
android:id="@+id/edit"
android:layout_width="fill_parent"
android:layout_height="wrap_content" />
android:id="@+id/edit1"
android:layout_width="fill_parent"
android:layout_height="wrap_content"
android:password="true" />
android:layout_width="fill_parent"
android:layout_height="wrap_content" >
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" />
android:layout_width="fill_parent"
android:layout_height="fill_parent"
android:orientation="vertical" >
android:id="@+id/edit"
android:layout_width="fill_parent"
android:layout_height="wrap_content" />
android:id="@+id/edit1"
android:layout_width="fill_parent"
android:layout_height="wrap_content"
android:password="true" />
android:layout_width="fill_parent"
android:layout_height="wrap_content" >
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" />
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
