EditText使用小结

一：新建HelloEditText工程

<wbr><wbr></wbr></wbr>

新建一个Helloworld详细步骤可以参见

Android教程之三：第一个Android应用，HelloWorld

创建设置如下：

  1. Projectname:<wbr><wbr><span style="font-size:12px"><span style="font-size:12px">HelloEditText</span></span></wbr></wbr>
  2. Build Target :android2.2
  3. Applicationname:HelloEditText
  4. Packagename:com.flysnow
  5. createActivity:<wbr><wbr><span style="font-size:12px"><span style="font-size:12px">HelloEditText</span></span></wbr></wbr>
  6. min SDK8

<wbr><wbr>这时候运行还看不到EditText，因为我们还没有加上,修改main.xml如下：</wbr></wbr>

Xml代码<wbr><wbr> "quality="high" allowscriptaccess="always"type="application/x-shockwave-flash"pluginspage="http://www.macromedia.com/go/getflashplayer"&gt;</wbr></wbr>

  12. </LinearLayout><wbr><wbr><wbr><wbr></wbr></wbr></wbr></wbr>

<wbr><wbr>这里添加了一个id为"edit_text"的EditText，设置默认显示为本为“这是一个EditText”。</wbr></wbr>

二：EditText简介

EditText是一个非常重要的组件，可以说它是用户和Android应用进行数据传输窗户，有了它就等于有了一扇和Android应用传输的门，通过它用户可以把数据传给Android应用，然后得到我们想要的数据。

EditText是TextView的子类，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Android系列教程之六：TextView小组件的使用--附带超链接和跑马灯效果

<wbr><wbr></wbr></wbr>

三：长度和空白提示文字,提示文字颜色,是否可编辑等

EditText有一些属性可以设置EditText的特性，比如最大长度，空白提示文字等。

  1. 有时候我们有一些特属的需要，要求只能在EditText中输入特定个数的字符，比如身份证号、手机号吗等。这时候就可以通过android:maxLength属性来设置最大输入字符个数，比如android:maxLength=“4”就表示最多能输入4个字符，再多了就输入不进去了。
  2. 空白提示文字。有时候我们需要说明你定义的这个EditText是做什么用的，比如让输入“用户名”，或者输入“电话号码”等，但是你又不想在EditText前面加一个TextView来说明这是输入“用户名”的，因为这会使用一个TextView，那么怎么办呢？EditText为我们提供了android:hint来设置当EditText内容为空时显示的文本，这个文本只在EditText为空时显示，你输入字符的时候就消失了，不影响你的EditText的文本。。修改main.xml如下：<wbr><wbr><br><div style="padding-right:1px;

  3. 上面列出了空白时的提示文字，有的人说了，我不想要这个灰色的提示文字，和我的应用整体风格不协调，那也行啊，我们可以换颜色，怎么换呢，就是通过android:textColorHint属性设置你想要的颜色。修改main.xml如下:
    Xml代码<wbr><wbr> "quality="high" allowscriptaccess="always"type="application/x-shockwave-flash"pluginspage="http://www.macromedia.com/go/getflashplayer"&gt;</wbr></wbr>
    1. <?xml<wbr><wbr></wbr></wbr>version="1.0"<wbr><wbr></wbr></wbr>encoding="utf-8"?><wbr><wbr><wbr><wbr></wbr></wbr></wbr></wbr>
    2. <LinearLayout<wbr><wbr></wbr></wbr>xmlns:android="http://schemas.android.com/apk/res/android"<wbr><wbr><wbr><wbr></wbr></wbr></wbr></wbr>
    3. <wbr><wbr><wbr><wbr><wbr><wbr><wbr><wbr><span style="color:red">android:orientation</span><span style="color:black">=</span><span style="color:blue">"vertical"</span><span style="color:black"><wbr><wbr><wbr><wbr></wbr></wbr></wbr></wbr></span></wbr></wbr></wbr></wbr></wbr></wbr></wbr></wbr>
    4. <wbr><wbr><wbr><wbr><wbr><wbr><wbr><wbr><span style="color:red">android:layout_width</span><span style="color:black">=</span><span style="color:blue">"fill_parent"</span><span style="color:black"><wbr><wbr><wbr><wbr></wbr></wbr></wbr></wbr></span></wbr></wbr></wbr></wbr></wbr></wbr></wbr></wbr>
    5. <wbr><wbr><wbr><wbr><wbr><wbr><wbr><wbr><span style="color:red">android:layout_height</span><span style="color:black">=</span><span style="color:blue">"fill_parent"</span><span style="color:black"><wbr><wbr><wbr><wbr></wbr></wbr></wbr></wbr></span></wbr></wbr></wbr></wbr></wbr></wbr></wbr></wbr>
    6. <wbr><wbr><wbr><wbr><wbr><wbr><wbr><wbr><span style="color:#06699; font-weight:bold">&gt;</span><span style="color:black"><wbr><wbr><wbr><wbr></wbr></wbr></wbr></wbr></span></wbr></wbr></wbr></wbr></wbr></wbr></wbr></wbr>
    7. <EditText<wbr><wbr><wbr><wbr></wbr></wbr></wbr></wbr>
    8. <wbr><wbr><wbr><wbr><wbr><wbr><wbr><wbr><span style="color:red">android:id</span><span style="color:black">=</span><span style="color:blue">"@+id/edit_text"</span><span style="color:black"><wbr><wbr><wbr><wbr><wbr><wbr><wbr><wbr></wbr></wbr></wbr></wbr></wbr></wbr></wbr></wbr></span></wbr></wbr></wbr></wbr></wbr></wbr></wbr></wbr>
    9. <wbr><wbr><wbr><wbr><wbr><wbr><wbr><wbr><span style="color:red">android:layout_width</span><span style="color:black">=</span><span style="color:blue">"fill_parent"</span><span style="color:black"><wbr><wbr><wbr><wbr><wbr><wbr></wbr></wbr></wbr></wbr></wbr></wbr></span></wbr></wbr></wbr></wbr></wbr></wbr></wbr></wbr>
    10. <wbr><wbr><wbr><wbr><wbr><wbr><wbr><wbr><span style="color:red">android:layout_height</span><span style="color:black">=</span><span style="color:blue">"wrap_content"</span><span style="color:black"><wbr><wbr><wbr><wbr></wbr></wbr></wbr></wbr></span></wbr></wbr></wbr></wbr></wbr></wbr></wbr></wbr>
    11. <wbr><wbr><wbr><wbr><wbr><wbr><wbr><wbr><span style="color:red">android:maxLength</span><span style="color:black">=</span><span style="color:blue">"40"</span><span style="color:black"><wbr><wbr><wbr><wbr></wbr></wbr></wbr></wbr></span></wbr></wbr></wbr></wbr></wbr></wbr></wbr></wbr>
    12. <wbr><wbr><wbr><wbr><wbr><wbr><wbr><wbr><span style="color:red">android:hint</span><span style="color:black">=</span><span style="color:blue">"请输入用户名..."</span><span style="color:black"><wbr><wbr><wbr><wbr></wbr></wbr></wbr></wbr></span></wbr></wbr></wbr></wbr></wbr></wbr></wbr></wbr>
    13. <wbr><wbr><wbr><wbr><wbr><wbr><wbr><wbr><span style="color:red">android:textColorHint</span><span style="color:black">=</span><span style="color:blue">"#238745"</span><span style="color:#06699; font-weight:bold">/&gt;</span><span style="color:black"><wbr><wbr><wbr><wbr></wbr></wbr></wbr></wbr></span></wbr></wbr></wbr></wbr></wbr></wbr></wbr></wbr>
    14. </LinearLayout><wbr><wbr><wbr><wbr></wbr></wbr></wbr></wbr>


    <wbr><wbr>看到了吧，颜色已经变了。。</wbr></wbr>
  4. 还有一个比较实用的功能，就是设置EditText的不可编辑。设置android:enabled="false"可以实现不可编辑，可以获得焦点。这时候我们看到EditText和一个TextView差不多：<wbr><wbr><br><br><wbr><wbr></wbr></wbr></wbr></wbr>
  5. 实现类似html中Textarea的文本域。在Android中没有专门的文本域组件，但是可以通过设置EditText的高来实现同样的文本域功能。修改main.xml如下:<wbr><wbr><br><div style="padding-right:1px; overflow-y:auto; padding-left:1px; font-size:12px; overflow-x:auto; padding-bottom:1px; margin-left:9px; width:646px; word-break:break-all; padding-top:1px; font-family:Monaco,'DejaVu sans Mono','Bitstream Vera sans Mono',Consolas,'Courier new',monospace; background-color:transparent; word-wrap:break-word"> <div> <div style="padding-right:3px; padding-left:3px; font-weight:bold; padding-bottom:3px; margin:0px; color:black; padding-top:3px; text-align:left"> Xml代码<wbr><wbr> "quality="high" allowscriptaccess="always"type="application/x-shockwave-flash"pluginspage="http://www.macromedia.com/go/getflashplayer"&gt;</wbr></wbr> </div> </div> <ol style="border-right:rgb(209,215,220) 1px solid;

四：输入特殊格式的字符

在我们开发程序的时候不免会输入一些特属个数的字符，比如密码（输入框的字符要加密显示），电话号码（比如数字和-）,数字等，这些都算是一些特属格式的字符，强大的EditText同样为我们提供了输入这些特属格式字符的设置。

  1. 密码文本框。密码输入也是Android应用常用的功能，通过配置EditText的android:password="true"就可以实现这一密码输入功能，修改main.xml如下：<wbr><wbr><br><div style="padding-right:1px; overflow-y:auto; padding-left:1px; font-size:12px; overflow-x:auto;

  2. 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<wbr><wbr>).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。修改main.xml如下：</wbr></wbr><wbr><wbr><br><div style="padding-right:1px;

  3. 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)。这里以signed类型的为例，修改main.xml如下：<wbr><wbr><br><div style="padding-right:1px; overflow-y:auto;

五：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，这里使用date类型来演示,修改main.xml如下：<wbr><wbr><strong style="font-weight:bold"><span style="color:#c000"><br></span></strong></wbr></wbr>

Xml代码<wbr><wbr> "quality="high" allowscriptaccess="always"type="application/x-shockwave-flash"pluginspage="http://www.macromedia.com/go/getflashplayer"&gt;</wbr></wbr>
  1. <?xml<wbr><wbr></wbr></wbr>version="1.0"<wbr><wbr></wbr></wbr>encoding="utf-8"?><wbr><wbr><wbr><wbr></wbr></wbr></wbr></wbr>

六：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：

  1. actionUnspecified<wbr><wbr>未指定，对应常量EditorInfo.IME_ACTION_UNSPECIFIED.效果：</wbr></wbr>
  2. actionNone没有动作,对应常量EditorInfo.IME_ACTION_NONE 效果：
  3. actionGo去往，对应常量EditorInfo.IME_ACTION_GO 效果：
