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();
...
