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

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>
    ArrayAdapter<String> countries = new ArrayAdapter<String>(this,android.R.layout.simple_dropdown_item_1line,getResources().getStringArray(R.array.countries_arry));
    AutoCompleteTextView autoText = (AutoCompleteTextView)findViewById(R.id.autoCompleteTextView1);
    autoText.setAdapter(countries);
    autoText.addTextChangedListener(new TextWatcher(){
    
    	@Override
    	public void afterTextChanged(Editable arg0) {
    	}
    
    	@Override
    	public void beforeTextChanged(CharSequence arg0, int arg1,
    					int arg2, int arg3) {
    	}
    
    	@Override
    	public void onTextChanged(CharSequence value, int arg1, int arg2,
    					int arg3) {
    		Log.d("AutoCompleteTextActivity", value.toString());
    	}
    });
        <AutoCompleteTextView
            android:id="@+id/autoCompleteTextView1"
            android:layout_width="match_parent"
            android:layout_height="wrap_content"
            android:ems="10"
            android:completionThreshold="2"
            android:text="AutoCompleteTextView">
    <?xml version="1.0" encoding="utf-8"?>
    <TextView xmlns:android="http://schemas.android.com/apk/res/android"

        android:layout_width="wrap_content"
        android:layout_height="wrap_content"
        android:padding="10dp"
        android:textColor="#0000aa"
        android:textSize="16sp" />
    ArrayAdapter<String> countries = new ArrayAdapter<String>(this,R.layout.listitem,getResources().getStringArray(R.array.countries_arry));
