The Link for Support4Demos is changed or can be changed so posting the complete solution. Here it goes.
-
Create attrs.xml file in res/values folder. Or add the below content if file already exists.
<?xml version="1.0" encoding="utf-8"?> <resources> <declare-styleable name="MyFragment"> <attr name="my_string" format="string"/> <attr name="my_integer" format="integer"/> </declare-styleable>
-
Override the onInflate delegate of fragment and read attributes in it
/** * Parse attributes during inflation from a view hierarchy into the * arguments we handle. */ @Override public void onInflate(Activity activity, AttributeSet attrs, Bundle savedInstanceState) { super.onInflate(activity, attrs, savedInstanceState); Log.v(TAG,"onInflate called"); TypedArray a = activity.obtainStyledAttributes(attrs,R.styleable.MyFragment); CharSequence myString = a.getText(R.styleable.MyFragment_my_string); if(myString != null) { Log.v(TAG, "My String Received : " + myString.toString()); } int myInteger = a.getInt(R.styleable.AdFragment_my_integer, -1); if(myInteger != -1) { Log.v(TAG,"My Integer Received :" + myInteger); } a.recycle(); }
-
Pass these attributes in your layout file as following. Just an example
<?xml version="1.0" encoding="utf-8"?> <RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android" xmlns:app="http://schemas.android.com/apk/res-auto" android:layout_width="match_parent" android:layout_height="match_parent" > <TextView android:layout_width="wrap_content" android:layout_height="wrap_content" android:text="This is android activity" /> <fragment android:id="@+id/ad_fragment" android:name="com.yourapp.packagename.MyFragment" android:layout_width="fill_parent" android:layout_height="50dp" android:layout_alignParentBottom="true" app:my_string="Hello This is HardCoded String. Don't use me" app:my_integer="30" /> </RelativeLayout>
Thats all. Its a working solution.
While doing this if you see any namespace error in xml.
try project cleaning again and again.
This is pathetic but Eclipse and adt misbehaves sometimes.
