Android 自定义密码键盘

原来自己很懒没有写过博客，所以样式凑合着看吧，近期因为项目的需求，需要自定义键盘，但是在网上找的都不符合自己的要求，所以索性自己开发，说实话自定义键盘是很简单的，但是在做点击键盘上的按键提示PopupWindow计算位置时真费心，好了废话不多说了，来看代码吧！

一、自定义键盘思路

1.英文字母view(包括大小写)

2.数字键盘view

3.标点符号键盘view

4.特殊键的处理

5.屏蔽原生键盘的显示方法

6.点击键盘有PopupWindow提示

二、界面布局

1.英文字母键盘布局

5.特殊键的处理

返回键，当按返回键时，首先隐藏自定义键盘，然后退出程序

6.屏蔽原生键盘的弹出，显示自定义键盘

说明：隐藏原生键盘的方法有两个判断的原因是：4.0用反射调用setShowSoftInputOnFocus方法，此方法为4.0新增，2.3仍用 mEtInput.setInputType(InputType.TYPE_NULL)

private void disableSysKeyboard() {
if (android.os.Build.VERSION.SDK_INT <= 10) {
code_input.setInputType(InputType.TYPE_NULL);
} else {
getWindow().setSoftInputMode(WindowManager.LayoutParams.SOFT_INPUT_STATE_ALWAYS_HIDDEN);
try {
Class<EditText> cls = EditText.class;
Method setShowSoftInputOnFocus;
setShowSoftInputOnFocus = cls.getMethod("setShowSoftInputOnFocus", boolean.class);
setShowSoftInputOnFocus.setAccessible(true);
setShowSoftInputOnFocus.invoke(code_input, false);
} catch (Exception e) {
e.printStackTrace();
}
}
}

7.点击键盘显示PopupWindow

在我的demo中，显示PopupWindow的方法放在了ontouch里面，dowm的时候显示，up的时候PopupWindow消失

三、demo截图

> 1.![数字键盘](http://img.blog.csdn.net/20160627111339550)
> 2.![字母键盘](http://img.blog.csdn.net/20160627111403934)
> 3.![符号键盘](http://img.blog.csdn.net/20160627111426044)
> 4.![点击数字键盘显示pop](http://img.blog.csdn.net/20160627111453091)

四、demo说明

1.只有数据键盘界面添加了pop的显示，如果别的界面有需求，自己加上
2.在数字键盘上有一个问题，当触碰到键盘的时候，显示pop，但是ed上没有输入上数字，原因：showtext的方法在onclick里面调用
解决办法：showtext放到ontouch方法中的down事件中即可

至于为什么？自己去看onclick和ontouch的源码，搞清楚执行顺序，你就明白了，哈哈哈！！！！
