I am following this link : android spinner fire event when same item selection is made
I extended Spinner class as mentioned in the link. Below is my code:
public class SpinnerTrigger extends Spinner { public SpinnerTrigger(Context context) { super(context); // TODO Auto-generated constructor stub } @Override public void setSelection(int position, boolean animate) { ignoreOldSelectionByReflection(); super.setSelection(position, animate); } private void ignoreOldSelectionByReflection() { try { Class<?> c = this.getClass().getSuperclass().getSuperclass().getSuperclass(); Field reqField = c.getDeclaredField("mOldSelectedPosition"); reqField.setAccessible(true); reqField.setInt(this, -1); } catch (Exception e) { Log.d("Exception Private", "ex", e); // TODO: handle exception } } @Override public void setSelection(int position) { ignoreOldSelectionByReflection(); super.setSelection(position); } } I added the above class in my layout file with fully qualified name:
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android" xmlns:tools="http://schemas.android.com/tools" android:layout_width="match_parent" android:layout_height="match_parent" android:paddingBottom="@dimen/activity_vertical_margin" android:paddingLeft="@dimen/activity_horizontal_margin" android:paddingRight="@dimen/activity_horizontal_margin" android:paddingTop="@dimen/activity_vertical_margin" android:orientation="vertical" tools:context=".MainActivity" > <com.mypack.cc.SpinnerTrigger android:id="@+id/spinner1" android:layout_width="wrap_content" android:layout_height="wrap_content" android:entries="@array/options" android:prompt="@string/text_prompt" /> </LinearLayout> When I am trying run my application, I am getting error logs as mentioned below:
Caused by: android.view.InflateException: Binary XML file line #12:Error inflating class com.mypack.cc.SpinnerTrigger Please suggest me If I miss something here.
