Utilisez declare styleable pour définir le type d'entrée de composant personnalisé
J'ai un CompositeComponent (EditText + ImageButton) En cliquant sur le bouton, le contenu d'edittext sera effacé . Il fonctionne bien Mon problème est de définir des attributs pour mon composant. J'utilise declare-styleable pour définir les attributs de mon composant.
Je réussis à définir minLines, maxLines et textColor.
Comment définir le type d'entrée sur mon composant via XML?.
mes attributs.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>
Et utilisation de mycomponent dans main_layout.xml:
<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>
Utilisation ordinaire d'Edittext:
<EditText
Android:id="@+id/editText1"
Android:layout_width="match_parent"
Android:layout_height="wrap_content"
Android:inputType="numberSigned" <--------I want to use this property--------> >
Je ne peux pas utiliser ENUM dans mon attribut.xml . Comment faire référence à Android:inputType="numberSigned" dans mon cet:InputType?
MODIFIER:
C’est ainsi que j’assigne des propriétés dans mon fichier ClearableEditText.Java.
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);
Vous pouvez constater qu'il n'y a pas de problème d'affectation de la propriété inputType à editText.
Disons que vous avez une vue personnalisée appelée InputView, qui n'est pas une vue TextView (disons que c'est un RelativeLayout).
Dans votre attrs.xml:
<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>
Dans une mise en page XML où vous souhaitez inclure InputView:
<!-- 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>
Dans votre classe personnalisée, vous pouvez extraire les attributs comme d'habitude:
...
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();
...
utilisez ceci dans votre attr.xml pour les suggestions. l'utilisation d'indicateurs donne les suggestions au format xml lors de l'utilisation de edittext . custom: inputType = "text" et il vous proposera les types d'addition . pour ajouter d'autres indicateurs utilisez ce lien. https://Android.googlesource.com/platform/frameworks/base/+/refs/heads/master/core/res/res/values/attrs.xml

J'ai réussi à le faire avec une valeur int brute: Je pense que ce n'est pas une bonne pratique . Je peux attribuer des valeurs brutes comme ceci: cet:InputType="2"
2 pour numéro (référencé pour les valeurs: http://developer.Android.com/reference/Android/text/InputType.html#TYPE_CLASS_NUMBER et http://developer.Android.com/reference/Android/ R.styleable.html # TextView_inputType )
Je crois que <attr name="InputType" format="reference" /> peut aider mais je ne sais pas comment l'utiliser.
Bon, alors je sais que cette question est assez ancienne mais j’ai trouvé la vraie réponse.
J'ai trouvé le fichier attrs.xml dans ici qu'Android utilise et que chaque declare_styleable est présent. Vous pouvez donc trouver l'attribut inputType défini ci-dessous à partir des attributs standard.
<!-- 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. -->

Donc vous avez 2 choix, si vous devez changer le nom de inputType en un autre nom (i.e title_inputType), alors vous devez copier tout cela, mais si vous devez conserver le même nom, utilisez/ Réponse d'Alexey
