刚刚做了个自定义键盘，方法记录下来以便以后用到参考，界面主要有一个editText和键盘。刚开始的时候我是用PopupWindow做的软键盘，后来发现不好用，因为PopupWindow和
editText不在一个层，每次点击键盘时EditText就没有焦点，
如果我输入了123456，现在想在2后面输入一个小数点，结果还要点击一下editText才能获得焦点，而此时popupWindow键盘会
消失，想输入只有再次点击editText后，popupWindow键盘才能显示出来，最后也没有找到解决的办法，所以我用了第二种方法比较简单。相对布局把键盘固定在最底部，别的不多说，先上图再上代码吧。
一、这是效果图，比较丑。。。
二、这个是自定义键盘的xml文档，comm_keyboard.xml
<?xml version="1.0" encoding="utf-8"?> <LinearLayout xmlns:android="http://schemas.android.com/apk/res/android" android:layout_width="match_parent" android:layout_height="wrap_content" android:orientation="vertical" > <LinearLayout android:id="@+id/keyboard_layout" android:layout_width="match_parent" android:layout_height="225dip" android:layout_alignParentBottom="true" android:background="#f6f6f7" android:orientation="horizontal" > <TableLayout android:layout_width="0dip" android:layout_height="match_parent" android:layout_weight="1" > <TableRow> <Button android:id="@+id/custom_keyboard_btn1" android:layout_width="0dip" android:layout_height="55dip" android:layout_weight="1" android:background="@drawable/table_line_gray" android:gravity="center" android:text="1" android:textColor="#000000" android:textSize="30sp" /> <Button android:id="@+id/custom_keyboard_btn2" android:layout_width="0dip" android:layout_height="55dip" android:layout_weight="1" android:background="@drawable/table_line_gray" android:gravity="center" android:text="2" android:textColor="#000000" android:textSize="30sp" /> <Button android:id="@+id/custom_keyboard_btn3" android:layout_width="0dip" android:layout_height="55dip" android:layout_weight="1" android:background="@drawable/table_line_gray" android:gravity="center" android:text="3" android:textColor="#000000" android:textSize="30sp" /> </TableRow> <TableRow> <Button android:id="@+id/custom_keyboard_btn4" android:layout_width="0dip" android:layout_height="55dip" android:layout_weight="1" android:background="@drawable/table_line_gray" android:gravity="center" android:text="4" android:textColor="#000000" android:textSize="30sp" /> <Button android:id="@+id/custom_keyboard_btn5" android:layout_width="0dip" android:layout_height="55dip" android:layout_weight="1" android:background="@drawable/table_line_gray" android:gravity="center" android:text="5" android:textColor="#000000" android:textSize="30sp" /> <Button android:id="@+id/custom_keyboard_btn6" android:layout_width="0dip" android:layout_height="55dip" android:layout_weight="1" android:background="@drawable/table_line_gray" android:gravity="center" android:text="6" android:textColor="#000000" android:textSize="30sp" /> </TableRow> <TableRow> <Button android:id="@+id/custom_keyboard_btn7" android:layout_width="0dip" android:layout_height="55dip" android:layout_weight="1" android:background="@drawable/table_line_gray" android:gravity="center" android:text="7" android:textColor="#000000" android:textSize="30sp" /> <Button android:id="@+id/custom_keyboard_btn8" android:layout_width="0dip" android:layout_height="55dip" android:layout_weight="1" android:background="@drawable/table_line_gray" android:gravity="center" android:text="8" android:textColor="#000000" android:textSize="30sp" /> <Button android:id="@+id/custom_keyboard_btn9" android:layout_width="0dip" android:layout_height="55dip" android:layout_weight="1" android:background="@drawable/table_line_gray" android:gravity="center" android:text="9" android:textColor="#000000" android:textSize="30sp" /> </TableRow> <TableRow> <Button android:id="@+id/custom_keyboard_btn_point" android:layout_width="0dip" android:layout_height="59dip" android:layout_weight="1" android:background="@drawable/table_line_gray" android:gravity="center" android:text="." android:textColor="#000000" android:textSize="30sp" /> <Button android:id="@+id/custom_keyboard_btn0" android:layout_width="0dip" android:layout_height="59dip" android:layout_weight="1" android:background="@drawable/table_line_gray" android:gravity="center" android:text="0" android:textColor="#000000" android:textSize="30sp" /> <Button android:id="@+id/custom_keyboard_btn_system_keyboard" android:layout_width="0dip" android:layout_height="match_parent" android:layout_weight="1" android:background="@drawable/table_line_gray" android:gravity="center" android:text="系统键" android:textColor="#000000" android:textSize="15sp" /> </TableRow> </TableLayout> <LinearLayout android:layout_width="90dip" android:layout_height="match_parent" android:orientation="vertical" > <Button android:id="@+id/custom_keyboard_btn_delete" android:layout_width="match_parent" android:layout_height="0dip" android:layout_weight="1" android:background="@drawable/table_line_gray" android:gravity="center" android:text="删除" android:textColor="#000000" android:textSize="20sp" /> <Button android:id="@+id/custom_keyboard_btn_sure" android:layout_width="match_parent" android:layout_height="0dip" android:layout_weight="1" android:background="@drawable/table_line_gray" android:gravity="center" android:text="确定" android:textSize="20sp" /> </LinearLayout> </LinearLayout> </LinearLayout>
这是activity_main.xml文档
