经过一些Android中EditText方面的折腾：
【已解决】android中的EditText控件没有获得焦点但是输入法却弹出显示->Activity中不要默认就显示输入法
【暂未去解决】Android中EditText如何在失去焦点后让输入法消失
【已解决】Android中EditText点击获得焦点后无法显示输入法键盘
【已解决】Android中代码出现警告提示：android:phoneNumber is deprecated: Use inputType instead
然后对于EditText（或TextView）中的InputType的值的含义和类型，以及如何定义，有了个更清晰点的认识。
现在整理如下：
EditText的InputType属性，可以在代码中设置，也可以预先在xml中定义
设置EditText的InputType属性，最简单省事的办法就是在定义EditText的xml中直接设置。
比如：
想要设置一个可编辑的文本框的输入内容为只能输入数字，则就可以：
（1）xml中定义InputType为number
|
1
2
3
4
|
<EditText android:id="@+id/variableValue"
......
android:inputType="number" />
|
（2）代码中设置InputType为TYPE_CLASS_NUMBER | TYPE_NUMBER_VARIATION_NORMAL
|
1
2
3
|
EditText variableValueView = (EditText) variableLayout.findViewById(R.id.variableValue);int inputType = InputType.TYPE_CLASS_NUMBER | InputType.TYPE_NUMBER_VARIATION_NORMAL;
variableValueView.setInputType(inputType); |
这样的话，之后界面中生成的EditText，当点击后要输入内容的时候，弹出的输入法，自动变成那种只能输入数字的小键盘类型的了：
另外，附上，正常的普通字符串，即：
xml中：
|
1
|
android:inputType="text" |
或代码中：
|
1
|
someEditText.setInputType(InputType.TYPE_CLASS_TEXT | InputType.TYPE_TEXT_VARIATION_NORMAL); |
时，显示出来的输入法键盘的效果：
EditText的InputType属性对应的xml定义有哪些，以及代码中设置的InputType类型有哪些
知道了设置EditText的InputType属性值，既可以通过xml中定义，也可以在代码中设置为InputType的某种值，但是到底这些值有哪些，以及分别对应的含义是啥，则可以参考官网：

如此，就可以自己去在xml或代码中，分别试试，每种不同的InputType对应的都是什么效果了。
注意：通过代码给InputType赋值时，不是设置TYPE_XXX_VARIATION_YYY，而是要设置TYPE_CLASS_XXX | TYPE_XXXX_VARAITION_YYY
之前在代码中给InputType设置值，错写成：
|
1
|
inputType = InputType.TYPE_DATETIME_VARIATION_TIME; |
导致，EditText点击后，不显示输入法键盘，改为正确的：
|
1
|
inputType = InputType.TYPE_CLASS_DATETIME | InputType.TYPE_DATETIME_VARIATION_TIME; |
就可以正常的显示键盘了。
而后，也注意到官网
InputType | Android Developers
的解释中的示例：
|
以及
TextView | Android Developers – android:inputType
中提示的：
“Must be one or more (separated by ‘|’) of the following constant values.”
即：
需要一个或多个值，中间通过竖杠"|"去抑或（按位或）的。
