I have created my own custom spinner which I can access from "Custom and library views" as it implements View . But, the problem is that when drag my custom spinner from palette to use it in my main.xml , it throws "unhandled event loop exception". I don't know where is my mistake. main.xml <?xml version="1.0" encoding="utf-8"?> <LinearLayout xmlns:android="http://schemas.android.com/apk/res/android" xmlns:pref="http://schemas.android.com/apk/res/com.myspinner" android:layout_width="fill_parent" android:layout_height="fill_parent" android:orientation="vertical" > <com.myspinner.Myspinner android:id="@+id/myspinner1" android:layout_width="match_parent" android:layout_height="wrap_content" pref:MyEntries="@array/testarray" /> MySpinnerattributes.xml <?xml version="1.0" encoding="utf-8"?> <resources> <declare-styleable name="MySpinner"> <attr name="MyEntries" format="reference"/> </declare-styleable> </resources> spinnerlayout.xml <?xml version="1.0" encoding="utf-8"?> <TextView xmlns:android="http://schemas.android.com/apk/res/android" android:id="@+id/textView1" android:layout_width="match_parent" android:layout_height="match_parent" android:layout_gravity="center" android:text="@string/large_text" android:gravity="center"/> Myspinner.java public class Myspinner extends Spinner{ LayoutInflater inflater; CharSequence cs[]={"MySpinner"}; String s[]={"MySpinner"}; View row; TextView txt; public Myspinner(Context context, AttributeSet attrs, int defStyle) { super(context, attrs, defStyle); setAttributes(attrs); this.setAdapter(new MyAdapter(this.getContext(), R.layout.spinnerlayout,s)); } publ
