Use declare styleable to set custom component input type

Question

I have a CompositeComponent (EditText+ImageButton) When clicking on button the edittext content will be cleared. It is working fine. My problem is setting attributes to my component. I am using declare-styleable to set attributes to my component.

I am successful at setting minLines, maxLines and textColor.

How can I set inputtype to my component via xml.

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> 

And usage of mycomponent in 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> 

Ordinary Edittext usage:

<EditText         android:id="@+id/editText1"         android:layout_width="match_parent"         android:layout_height="wrap_content"         android:inputType="numberSigned" <--------I want to use this property--------> > 

I cant use ENUM in my attribute.xml. How to refer android:inputType="numberSigned" in my cet:InputType?

EDIT:

This is how I assign properties in my 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); 

You can see there is no problem with assigning the inputType property to editText.

Lets say you have a custom view named InputView, which is not a TextView (lets say its a RelativeLayout).

In your 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> 

In an xml layout where you want to include 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> 

Inside your custom class you can extract attributes as usual:

    ...      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();     ...
