通过android:inputType可以指定EditText 的输入类型,比如输入数字,日期,密码或者邮件地址等。
下面列出常用的类型值:
text 普通文本的输入
textEmailAddress 包含“@”字符的文本输入(邮件地址)
textUri 包含“/”字符的输入
number 基本数字输入
phone 电话格式的输入
android:inputType控制输入行为
textCapWords 单词首字母大写,一般用于标题或者人名
textCapSentences 句子首个单词首字母大写,一般用于段落的开始
textCapCharacters 所有字符的大写
textAutoCorrect 纠正单词的拼写错误
textPassword 密码输入
textMultiLine 允许多行输入
android:inputType允许输入类型和输入行为按位组合的方式指定,比如:
1. <EditText
2. android:id="@+id/postal_address"
3. android:layout_width="fill_parent"
4. android:layout_height="wrap_content"
5. android:hint="@string/postal_address_hint"
6. android:inputType="textPostalAddress|
7. textCapWords|
8. />
<EditText
android:id="@+id/postal_address"
android:layout_width="fill_parent"
android:layout_height="wrap_content"
android:hint="@string/postal_address_hint"
android:inputType="textPostalAddress|
textCapWords|
textNoSuggestions" />
这我们就指定了为邮政地址(textPostalAddress),且地址单词子首字母大写(textCapWords),且不显示输入单词的词典建议(textNoSuggestions)。
指定键盘操作
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。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,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:
actionNext 软键盘不关闭,光标跳到下一个输入焦点位置(发送EditorInfo.IME_ACTION_NEXT命令)
actionGo 软键盘不关闭,光标跳到下一个输入焦点位置,发送EditorInfo.IME_ACTION_GO命令
actionSearch 软键盘不关闭,发送EditorInfo.IME_ACTION_SEARCH命令
actionSend 软键盘关闭,发送EditorInfo.IME_ACTION_SEND命令
actionDone 软键盘关闭,光标保持在原来的输入框上,发送EditorInfo.IME_ACTION_DONE命令

}
return handled;
}
}
效果如图:
设置一个自定义操作按钮标签
上面设置的键盘操作,的按钮文字都是系统默认设置,我们可以通过android:imeActionLabel属性来设置我们自定义的标签文本,如下:
1. <EditText
2. android:id="@+id/action_next"
3. android:layout_width="fill_parent"
4. android:layout_height="wrap_content"
5. android:hint="@string/action_next"
6. android:imeOptions="actionNext"
7. android:imeActionLabel="@string/action_next_text"
8. android:inputType="text" />
<EditText
android:id="@+id/action_next"
android:layout_width="fill_parent"
android:layout_height="wrap_content"
android:hint="@string/action_next"
android:imeOptions="actionNext"
android:imeActionLabel="@string/action_next_text"
android:inputType="text" />
在string.xml中设置为:
<div ><div ><div ><strong>[html]</strong> <a target=_blank title="view plain" href="">view plain</a><span data-mod="popu_168"> <a target=_blank title="copy" href="">copy</a></span><div style="left: 0px; top: 0px; width: 0px; height: 0px; position: absolute; z-index: 99;"></div><span data-mod="popu_169"> <a target=_blank title="print" href="">print</a></span><a target=_blank title="?" href="">?</a><span data-mod="popu_167"><a target=_blank title="在CODE上查看代码片" href="" target="_blank"><img width="12" height="12" style="position:relative;top:1px;left:2px;" alt="在CODE上查看代码片" src="" /></a></span><span data-mod="popu_170"><a target=_blank title="派生到我的代码片" href="/fork" target="_blank"><img width="12" height="12" style="position:relative;top:2px;left:2px;" alt="派生到我的代码片" src="" /></a></span></div></div><ol ><li ><span ><</span><span >string</span> <span >name</span>=<span >"action_next_text"</span><span >></span>下一个<span ></</span><span >string</span><span >></span> </li></ol><div data-mod="popu_249"><a><img src="" alt="" /></a></div></div><string name="action_next_text">下一个</string>
