android - programacion - Utilice declarar styleable para establecer el tipo de entrada de componente personalizado
manual de programacion android pdf (4)
Tengo un CompositeComponent (EditText + ImageButton) Al hacer clic en el botón, se borrará el contenido del texto de edición. Está funcionando bien. Mi problema es establecer atributos en mi componente. Estoy usando declare-styleable para establecer atributos en mi componente.
Tengo éxito en establecer minLines, maxLines y textColor.
¿Cómo puedo configurar el tipo de entrada en mi componente a través de xml?
mis atributos.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>
Y el uso de mycomponent en 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>
Uso ordinario de 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--------> >
No puedo usar ENUM en mi attribute.xml. Cómo referir a android:inputType="numberSigned" en mi cet:InputType ?
EDITAR:
Así es como asigno propiedades en mi 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);
Puede ver que no hay problema con la asignación de la propiedad inputType a editText.
De acuerdo, entonces sé que esta pregunta es bastante antigua, pero encontré la VERDADERA respuesta correcta.
Encontré el archivo attrs.xml here que usa Android y cada declare_styleable está allí, así que a partir de los atributos estándar puedes encontrar el atributo inputType que se define a continuación.
<!-- 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

indicated. Setting this attribute to anything besides

Así que tienes 2 opciones, si necesitas cambiar el nombre de inputType por otro nombre (es decir, title_inputType), entonces debes copiar todo esto, pero si necesitas mantener el mismo nombre, entonces usa la respuesta de Alexey
Digamos que tiene una vista personalizada llamada InputView, que no es un TextView (digamos que es un RelativeLayout).
En su 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>
En un diseño xml donde quiera incluir 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>
Dentro de tu clase personalizada puedes extraer atributos como de costumbre:
...
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();
...
Logré hacerlo con valor int en bruto: creo que no es una buena práctica. Puedo asignar valores en bruto como este: cet:InputType="2"
2 para el número (Referido para los valores: http://developer.android.com/reference/android/text/InputType.html#TYPE_CLASS_NUMBER y http://developer.android.com/reference/android/R.styleable.html#TextView_inputType )
Creo que <attr name="InputType" format="reference" /> puede ayudar pero no sabe cómo usarlo.
usa esto en tu attr.xml para las sugerencias. el uso de banderas da las sugerencias en xml al usar edittext. la costumbre: inputType = "text" y le sugerirá los tipos de adición. para agregar más banderas use este enlace Visite https://android.googlesource.com/platform/frameworks/base/+/refs/heads/master/core/res/res/values/attrs.xml
