スタイル可能な宣言を使用して、カスタムコンポーネントの入力タイプを設定します
CompositeComponent（EditText + ImageButton）があります。ボタンをクリックすると、edittextコンテンツがクリアされます。正常に動作しています。私の問題は、コンポーネントに属性を設定することです。私はdeclare-styleableを使用してコンポーネントに属性を設定しています。
MinLines、maxLines、textColorの設定に成功しています。
Xmlを使用してコンポーネントにinputtypeを設定するにはどうすればよいですか。
私の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>
Main_layout.xmlでのmycomponentの使用法：
<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>
通常のEdittextの使用法：
<EditText
Android:id="@+id/editText1"
Android:layout_width="match_parent"
Android:layout_height="wrap_content"
Android:inputType="numberSigned" <--------I want to use this property--------> >
Attribute.xmlでENUMを使用できません。参照方法Android:inputType="numberSigned"私のcet:InputType？
編集：
これは、ClearableEditText.Javaでプロパティを割り当てる方法です。
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);
InputTypeプロパティをeditTextに割り当てても問題はありません。
TextViewではないInputViewという名前のカスタムビューがあるとします（RelativeLayoutとしましょう）。
Attrs.xmlで：
<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>
InputViewを含めるxmlレイアウトで：
<!-- 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>
カスタムクラス内では、通常どおり属性を抽出できます。
...
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();
...
提案のためにattr.xmlでこれを使用してください。 edittextの使用中にフラグを使用すると、xmlで提案が提供されます。 custom：inputType = "text"を使用すると、追加タイプが提案されます。フラグを追加するには、このリンクを使用してください 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" />
<!--

私は生のint値でなんとかすることができました。それは良い習慣ではないと思います。このような生の値を割り当てることができます：cet:InputType="2"
数値の場合は2（値について参照： http://developer.Android.com/reference/Android/text/InputType.html#TYPE_CLASS_NUMBER および http://developer.Android.com /reference/Android/R.styleable.html#TextView_inputType ）
私は信じている <attr name="InputType" format="reference" />は役立ちますが、使用方法がわかりません。
さて、この質問はかなり古いことは知っていますが、本当の正解は見つかりました。
Attrs.xmlファイルは here that Androidが使用し、declare_styleableがすべて存在するため、以下のように定義されているinputType属性を見つけることができます。
<!-- 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. -->

したがって、2つの選択肢があります。inputTypeの名前を別の名前（つまりtitle_inputType）に変更する必要がある場合は、これをすべてコピーする必要がありますが、同じ名前を保持する必要がある場合は Alexeyの答え
