我有一个CompositeComponent（EditText + ImageButton） 单击按钮时，将清除edittext内容。 它工作正常。我的问题是为我的组件设置属性。我使用declare-styleable来设置我的组件的属性。
我成功设置了minLines，maxLines和textColor。
如何通过xml将inputtype设置为我的组件。
my attributes.xml
<?xml version="1.0" encoding="utf-8"?>
<resources>
<declare-styleable name="CET">
<attr name="MaxLines" format="integer"/>
<attr name="MinLines" format="integer"/>
<attr name="TextColor" format="color"/>
<attr name="InputType" format="integer" />
<attr name="Hint" format="string" />
</declare-styleable>
</resources>
在main_layout.xml中使用mycomponent：
<com.test.ui.ClearableEditText
xmlns:cet="http://schemas.android.com/apk/res/com.test.ui"
android:id="@+id/clearableEditText2"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
cet:MaxLines="2"
cet:MinLines="1"
cet:TextColor="#0000FF"
cet:InputType="" <---I cant set this property--------->
cet:Hint="Clearable EditText Hint">
</com.test.ui.ClearableEditText>
普通的Edittext用法：
<EditText
android:id="@+id/editText1"
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:inputType="numberSigned" <--------I want to use this property--------> >
我无法在我的attribute.xml中使用ENUM。
如何在android:inputType="numberSigned"中引用cet:InputType？
修改
这就是我在ClearableEditText.java
中指定属性的方法TypedArray a = getContext().obtainStyledAttributes(attrs,R.styleable.CET,0, 0);
int minLines = a.getInt(R.styleable.CET_MinLines, 1);
int maxLines = a.getInt(R.styleable.CET_MaxLines, 100);
String hint = a.getString(R.styleable.CET_Hint);
int textColor = a.getColor(R.styleable.CET_TextColor, Color.BLACK);
int inputType = a.getInt(R.styleable.CET_InputType, -108);
Log.i(TAG, "ClearableEditText: Min Line "+minLines +" Max Lines: "+maxLines+" Hint "+hint+" Color: "+textColor+" Input Type: "+inputType);
edit_text.setMaxLines(maxLines);
edit_text.setMinLines(minLines);
edit_text.setTextColor(textColor);
edit_text.setHint(hint);
if(inputType != -108)
edit_text.setInputType(inputType);
您可以看到将inputType属性分配给editText没有问题。

假设你有一个名为InputView的自定义视图，它不是TextView（比方说它是一个RelativeLayout）。
在你的attrs.xml中：
<declare-styleable name="InputView">
<!-- any custom attributes -->
<attr name="title" format="string" />
<!-- standart attributes, note android: prefix and no format attribute -->
<attr name="android:imeOptions"/>
<attr name="android:inputType"/>
</declare-styleable>
在要包含InputView的xml布局中：
<!-- note xmlns:custom and com.mycompany.myapp -->
<FrameLayout xmlns:android="http://schemas.android.com/apk/res/android"
xmlns:custom="http://schemas.android.com/apk/res-auto"
android:layout_width="fill_parent"
android:layout_height="fill_parent">
<!-- note that you will be using android: prefix for standart attributes, and not custom: prefix -->
<!-- also note that you can use standart values: actionNext or textEmailAddress -->
<com.mycompany.myapp.InputView
android:id="@+id/emailField"
android:layout_width="fill_parent"
android:layout_height="wrap_content"
custom:title="@string/my_title"
android:imeOptions="actionNext|flagNoExtractUi"
android:inputType="textEmailAddress" />
</FrameLayout>
在自定义类中，您可以照常提取属性：
...
private String title;
private int inputType;
private int imeOptions;
...
TypedArray a = getContext().obtainStyledAttributes(attrs, R.styleable.InputView);
int n = a.getIndexCount();
for (int i = 0; i < n; i++) {
int attr = a.getIndex(i);
switch (attr) {
case R.styleable.InputView_title:
title = a.getString(attr);
break;
//note that you are accessing standart attributes using your attrs identifier
case R.styleable.InputView_android_inputType:
inputType = a.getInt(attr, EditorInfo.TYPE_TEXT_VARIATION_NORMAL);
break;
case R.styleable.InputView_android_imeOptions:
imeOptions = a.getInt(attr, 0);
break;
default:
Log.d("TAG", "Unknown attribute for " + getClass().toString() + ": " + attr);
break;
}
}
a.recycle();
...

在attr.xml中使用它来获取建议。在使用edittext时，使用flags会在xml中给出建议。 自定义：inputType =“text” 它会建议你添加类型。 添加更多标志使用此链接 访问https://android.googlesource.com/platform/frameworks/base/+/refs/heads/master/core/res/res/values/attrs.xml
<resources>
<declare-styleable name="ClearableEditText">
<attr name="hintText" format="string" />
<attr name="inputType" format="integer">
<!-- There is no content type. The text is not editable. -->
<flag name="none" value="0x00000000" />
<!--
Just plain old text. Corresponds to
{@link android.text.InputType#TYPE_CLASS_TEXT} |
{@link android.text.InputType#TYPE_TEXT_VARIATION_NORMAL}.
-->
<flag name="text" value="0x00000001" />
<!--
Can be combined with <var>text</var> and its variations to
request capitalization of all characters. Corresponds to
{@link android.text.InputType#TYPE_TEXT_FLAG_CAP_CHARACTERS}.
-->
</attr>
</declare-styleable>
</resources>

我设法用raw int值做到了：
我认为这不是好习惯。
我可以像这样分配原始值：cet:InputType="2"
2代表数字（参考值：http://developer.android.com/reference/android/text/InputType.html#TYPE_CLASS_NUMBER和http://developer.android.com/reference/android/R.styleable.html#TextView_inputType）
我相信<attr name="InputType" format="reference" />可以提供帮助，但不知道如何使用它。

好的，所以我知道这个问题已经很老了，但是我找到了真正的正确答案。
我在here中找到了Android使用的attrs.xml文件，并且每个manifest_styleable都存在，因此从标准属性中可以找到定义如下的inputType属性
<!-- The type of data being placed in a text field used to help an
input method decide how to let the user enter text. The constants
here correspond to those defined by
{@link android.text.InputType}. Generally you can select
a single value, though some can be combined together as
indicated. Setting this attribute to anything besides
<var>none</var> also implies that the text is editable. -->
<attr name="inputType">
<!-- There is no content type. The text is not editable. -->
<flag name="none" value="0x00000000" />
<!-- Just plain old text. Corresponds to

</attr>
因此，您有2个选择，如果需要将inputType的名称更改为另一个名称（即title_inputType），则需要全部复制，但是如果需要保留相同的名称，请使用{{3 }}
