一、EditText简介

这里写图片描述 
EditText是一个非常重要的组件,常用来作为用户输入的文本框组件 
EditText是TextView的子类,可以看做是一个带有可编辑文本的TextView,所以TextView的方法和特性同样存在于EditText中,具体的TextView的介绍可以参考上一节“安卓开发学习之012 TextView高级应用”

二、基本使用

1. 限制最大输入字符个数

    android:maxLength="10"

2. 显示提示文字

    android:hint="hint!"

3. 文本颜色

    android:textColor="#0f0"

4. 提示文本颜色

    android:textColorHint="#f0f"        

5. 选中文本颜色

    android:textColorHighlight="#00f"   

这里写图片描述

6. 不可编辑 类似TextView

    android:enabled="false" 

7. 最大显示行数

    android:maxLines="3"    

三、输入特殊格式的字符

1.密码文本框

通过配置EditText的android:password=”true”就可以实现这一密码输入功能 
或者使用android:inputType=”textPassword”

2.电话号码文本框

手机中发短信打电话是必不可少的,所以用于专门输入电话号码的文本框也是大有用途,有了他我们对是否是电话号码的校验就容易的多了(因为字符是正确的,只要校验格式 ).通过设置android:phoneNumber=”true”就可以把EditText变成只接受电话号码输入的文本框,连软键盘都已经变成拨号专用软键盘了,所以不用再担心输入其他字符了

3.数字文本框

有时候我们只想输入数字,不想输入字母,EditText为我们提供了android:numeric来控制输入的数字类型,一共有三种分别为integer(正整数)、signed(带符号整数)和decimal(浮点数)

4.用户自定义输入

android:digits="1234567890xyzXYZ"这样用户只能输入上述指定的字符了

四、为文本指定特定的软键盘类型

前面我们通过指定为电话号码特定格式,然后键盘类型变成了拨号专用的键盘,这个是自动变的,其实我们也可以通 过android:inputType来设置文本的类型,让输入法选择合适的软键盘的 
android:inputType有很多类型 

none 
text 
textCapCharacters 
textCapWords 
textCapSentences 
textAutoCorrect 
textAutoComplete 
textMultiLine 
textImeMultiLine 
textNoSuggestions 
textUri 
textEmailAddress 
textEmailSubject 
textShortMessage 
textLongMessage 
textPersonName 
textPostalAddress 
textPassword 
textVisiblePassword 
textWebEditText 
textFilter 
textPhonetic 
textWebEmailAddress 
textWebPassword 
number 
numberSigned 
numberDecimal 
numberPassword 
phone 
datetime 
date 
time

五、Enter键图标的设置

软键盘的Enter键默认显示的是“完成”文本,我们知道按Enter建表示前置工作已经准备完毕了,要去什么什么啦。比如,在一个搜索中,我们输入要搜索的文本,然后按Enter表示要去搜索了,但是默认的Enter键显示的是“完成”文本,看着不太合适,不符合搜索的语义,如果能显示“搜索”两个字或者显示一个表示搜索的图标多好。事实证明我们的想法是合理的,Android也为我们提供的这样的功能。通过设置android:imeOptions来改变默认的“完成”文本。这里举几个常用的常量值: 
actionUnspecified 未指定,对应常量EditorInfo.IME_ACTION_UNSPECIFIED.效果:这里写图片描述 
actionNone 没有动作,对应常量EditorInfo.IME_ACTION_NONE 效果:这里写图片描述 
actionGo 去往,对应常量EditorInfo.IME_ACTION_GO 效果:这里写图片描述 
actionSearch 搜索,对应常量EditorInfo.IME_ACTION_SEARCH 效果:这里写图片描述 
actionSend 发送,对应常量EditorInfo.IME_ACTION_SEND 效果:这里写图片描述 
actionNext 下一个,对应常量EditorInfo.IME_ACTION_NEXT 效果:这里写图片描述 
actionDone 完成,对应常量EditorInfo.IME_ACTION_DONE 效果:这里写图片描述

<code class="hljs xml has-numbering" style="display: block; padding: 0px; color: inherit; box-sizing: border-box; font-family: 'Source Code Pro', monospace;font-size:undefined; white-space: pre; border-radius: 0px; word-wrap: normal; background: transparent;"> <span class="hljs-comment" style="color: rgb(136, 0, 0); box-sizing: border-box;"><!-- 改变enter键样式。要加android:singleLine="true" 否则样式不会变--></span>        <span class="hljs-tag" style="color: rgb(0, 102, 102); box-sizing: border-box;"><<span class="hljs-title" style="box-sizing: border-box; color: rgb(0, 0, 136);">EditText</span>            <span class="hljs-attribute" style="box-sizing: border-box; color: rgb(102, 0, 102);">android:layout_width</span>=<span class="hljs-value" style="box-sizing: border-box; color: rgb(0, 136, 0);">"wrap_content"</span>            <span class="hljs-attribute" style="box-sizing: border-box; color: rgb(102, 0, 102);">android:layout_height</span>=<span class="hljs-value" style="box-sizing: border-box; color: rgb(0, 136, 0);">"wrap_content"</span>            <span class="hljs-attribute" style="box-sizing: border-box; color: rgb(102, 0, 102);">android:text</span>=<span class="hljs-value" style="box-sizing: border-box; color: rgb(0, 136, 0);">"send"</span>            <span class="hljs-attribute" style="box-sizing: border-box; color: rgb(102, 0, 102);">android:singleLine</span>=<span class="hljs-value" style="box-sizing: border-box; color: rgb(0, 136, 0);">"true"</span>            <span class="hljs-attribute" style="box-sizing: border-box; color: rgb(102, 0, 102);">android:imeOptions</span>=<span class="hljs-value" style="box-sizing: border-box; color: rgb(0, 136, 0);">"actionSend"</span>            /></span></code><ul class="pre-numbering" style="box-sizing: border-box; position: absolute; width: 50px; top: 0px; left: 0px; margin: 0px; padding: 6px 0px 40px; border-right-width: 1px; border-right-style: solid; border-right-color: rgb(221, 221, 221); list-style: none; text-align: right; background-color: rgb(238, 238, 238);"><li style="box-sizing: border-box; padding: 0px 5px;">1</li><li style="box-sizing: border-box; padding: 0px 5px;">2</li><li style="box-sizing: border-box; padding: 0px 5px;">3</li><li style="box-sizing: border-box; padding: 0px 5px;">4</li><li style="box-sizing: border-box; padding: 0px 5px;">5</li><li style="box-sizing: border-box; padding: 0px 5px;">6</li><li style="box-sizing: border-box; padding: 0px 5px;">7</li><li style="box-sizing: border-box; padding: 0px 5px;">8</li></ul>

六、EditText的设置/获取选中文本

<code class="hljs avrasm has-numbering" style="display: block; padding: 0px; color: inherit; box-sizing: border-box; font-family: 'Source Code Pro', monospace;font-size:undefined; white-space: pre; border-radius: 0px; word-wrap: normal; background: transparent;"> EditText editText1= (EditText)findViewById(R<span class="hljs-preprocessor" style="color: rgb(68, 68, 68); box-sizing: border-box;">.id</span><span class="hljs-preprocessor" style="color: rgb(68, 68, 68); box-sizing: border-box;">.editText</span>01)<span class="hljs-comment" style="color: rgb(136, 0, 0); box-sizing: border-box;">;</span> Editable editable1= editText1<span class="hljs-preprocessor" style="color: rgb(68, 68, 68); box-sizing: border-box;">.getText</span>()<span class="hljs-comment" style="color: rgb(136, 0, 0); box-sizing: border-box;">;</span> //选中从第二个到末尾的文本 Selection<span class="hljs-preprocessor" style="color: rgb(68, 68, 68); box-sizing: border-box;">.setSelection</span>(editable1, <span class="hljs-number" style="color: rgb(0, 102, 102); box-sizing: border-box;">1</span>, editable1<span class="hljs-preprocessor" style="color: rgb(68, 68, 68); box-sizing: border-box;">.length</span>())<span class="hljs-comment" style="color: rgb(136, 0, 0); box-sizing: border-box;">;</span> int start= editText1<span class="hljs-preprocessor" style="color: rgb(68, 68, 68); box-sizing: border-box;">.getSelectionStart</span>()<span class="hljs-comment" style="color: rgb(136, 0, 0); box-sizing: border-box;">;</span> int end= editText1<span class="hljs-preprocessor" style="color: rgb(68, 68, 68); box-sizing: border-box;">.getSelectionEnd</span>()<span class="hljs-comment" style="color: rgb(136, 0, 0); box-sizing: border-box;">;</span> //获取选中文字System<span class="hljs-preprocessor" style="color: rgb(68, 68, 68); box-sizing: border-box;">.out</span><span class="hljs-preprocessor" style="color: rgb(68, 68, 68); box-sizing: border-box;">.println</span>(<span class="hljs-string" style="color: rgb(0, 136, 0); box-sizing: border-box;">"selected text = "</span> + editable1<span class="hljs-preprocessor" style="color: rgb(68, 68, 68); box-sizing: border-box;">.subSequence</span>(start, end))<span class="hljs-comment" style="color: rgb(136, 0, 0); box-sizing: border-box;">;</span></code><ul class="pre-numbering" style="box-sizing: border-box; position: absolute; width: 50px; top: 0px; left: 0px; margin: 0px; padding: 6px 0px 40px; border-right-width: 1px; border-right-style: solid; border-right-color: rgb(221, 221, 221); list-style: none; text-align: right; background-color: rgb(238, 238, 238);"><li style="box-sizing: border-box; padding: 0px 5px;">1</li><li style="box-sizing: border-box; padding: 0px 5px;">2</li><li style="box-sizing: border-box; padding: 0px 5px;">3</li><li style="box-sizing: border-box; padding: 0px 5px;">4</li><li style="box-sizing: border-box; padding: 0px 5px;">5</li><li style="box-sizing: border-box; padding: 0px 5px;">6</li><li style="box-sizing: border-box; padding: 0px 5px;">7</li><li style="box-sizing: border-box; padding: 0px 5px;">8</li></ul>

七、样式及背景设置

主要是设置android:background属性

<code class="hljs xml has-numbering" style="display: block; padding: 0px; color: inherit; box-sizing: border-box; font-family: 'Source Code Pro', monospace;font-size:undefined; white-space: pre; border-radius: 0px;

八、错误提示

用户输入信息错误时 使用 
EditText.setError(“”)设置错误信息 
代码如下:

<code class="hljs java has-numbering" style="display: block; padding: 0px; color: inherit; box-sizing: border-box; font-family: 'Source Code Pro', monospace;font-size:undefined; white-space: pre; border-radius: 0px;
