input type 有哪些. 分别是什么意思
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
<EditText
android:id="@+id/variableValue"
......
android:inputType="number" />
（2）代码中设置InputType为TYPE_CLASS_NUMBER | TYPE_NUMBER_VARIATION_NORMAL
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：
android:inputType="text"
或代码中：
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：
TextView | Android Developers – android:inputType
中的完整的列表：

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：
A password field with with the password visible to the user:
inputType = TYPE_CLASS_TEXT | TYPE_TEXT_VARIATION_VISIBLE_PASSWORD
A multi-line postal address with automatic capitalization:
inputType = TYPE_CLASS_TEXT | TYPE_TEXT_VARIATION_POSTAL_ADDRESS | TYPE_TEXT_FLAG_MULTI_LINE
A time field:
inputType = TYPE_CLASS_DATETIME | TYPE_DATETIME_VARIATION_TIME
以及

HTML标准的RFC
type
Used to set the type of input field:
type=text (the default)
A single line text field whose visible size can be set using the size attribute, e.g. size=40 for a 40 character wide field. Users should be able to type more than this limit though with the text scrolling through the field to keep the input cursor in view. You can enforce an upper limit on the number of characters that can be entered with the maxlength attribute. The name attribute is used to name the field, while the value attribute can be used to initialize the text string shown in the field when the document is first loaded.
<input type=text size=40 name=user value="your name">
type=password
This is like type=text, but echoes characters using a character like * to hide the text from prying eyes when entering passwords. You can use size and maxlength attributes to control the visible and maximum length exactly as per regular text fields.
<input type=password size=12 name=pw>
type=checkbox
Used for simple Boolean attributes, or for attributes that can take multiple values at the same time. The latter is represented by several checkbox fields with the same name and a different value attribute. Each checked checkbox generates a separate name/value pair in the submitted data, even if this results in duplicate names. Use the checked attribute to initialize the checkbox to its checked state.
<input type=checkbox checked name=uscitizen value=yes>
type=radio
Used for attributes which can take a single value from a set of alternatives. Each radio button field in the group should be given the same name. Radio buttons require an explicit value attribute. Only the checked radio button in the group generates a name/value pair in the submitted data. One radio button in each group should be initially checked using the checked attribute.
<input type=radio name=age value="0-12">
<input type=radio name=age value="13-17">
<input type=radio name=age value="18-25">
<input type=radio name=age value="26-35" checked>
<input type=radio name=age value="36-">
type=submit
This defines a button that users can click to submit the form's contents to the server. The button's label is set from the value attribute. If the name attribute is given then the submit button's name/value pair will be included in the submitted data. You can include several submit buttons in the form. See type=image for graphical submit buttons.
<input type=submit value="Party on ...">
type=image
This is used for graphical submit buttons rendered by an image rather than a text string. The URL for the image is specified with the src attribute. The image alignment can be specified with the align attribute. In this respect, graphical submit buttons are treated identically to IMG elements, so you can set align to left, right, top, middle or bottom. The x and y values of the location clicked are passed to the server: In the submitted data, image fields are included as two name/value pairs. The names are derived by taking the name of the field and appending ".x" for the x value, and ".y" for the y value.
<p>Now choose a point on the map:
<input type=image name=point src="map.gif">
Note: image fields typically cause problems for text-only and speech-based user agents!
type=reset
This defines a button that users can click to reset form fields to their initial state when the document was first loaded. You can set the label by providing a value attribute. Reset buttons are never sent as part of the form's contents.
<input type=reset value="Start over ...">
type=file
This provides a means for users to attach a file to the form's contents. It is generally rendered by text field and an associated button which when clicked invokes a file browser to select a file name. The file name can also be entered directly in the text field. Just like type=text you can use the size attribute to set the visible width of this field in average character widths. You can set an upper limit to the length of file names using the maxlength attribute. Some user agents support the ability to restrict the kinds of files to those matching a comma separated list of MIME content types given with the ACCEPT attribute e.g. accept="image/*" restricts files to images. Further information can be found in RFC 1867.
<input type=file name=photo size=20 accept="image/*">
type=hidden
These fields should not be rendered and provide a means for servers to store state information with a form. This will be passed back to the server when the form is submitted, using the name/value pair defined by the corresponding attributes. This is a work around for the statelessness of HTTP. Another approach is to use HTTP "Cookies".
<input type=hidden name=customerid value="c2415-345-8563">

舒建美格： 你没学过HTML么 input标签里面的两个唯一可以(正常情况)提交的二个type属性值就是submit和image,效果是一样的,只是书上说image说成是图片形按钮提交而已.如果method=get, image提交的时候地址栏会出现一个x=?&y=? 这样的东西,?表示数字,其它就是你点出按钮的位置.button正常是不能提交的,没有任何反应. 当然通过javascript可以使button也能实现提交.
鄂托克旗19764591281： form里的input有多少类型? - ？
舒建美格： input属性有: text radio checkbox file button image submit reset hidden submit是button的一个特例,也是button的一种,它把提交这个动作自动集成了. 如果表单在点击提交按钮后需要用JS进行处理(包括输入验证)后再提交的话,通常都必须把submit改成button, 即取消其自动提交的行为,否则,将会造成提交两次的效果,对于动态网页来说,也就是对数据库操作两次.麻烦采纳,谢谢!
