Corresponding method handler not found - Android XML
I had made a mistake in declaring the context in the XML. I had used .activities.YearViewActivity
but the changeMonth
method was declared in a different activity, which was causing the error.
<android.support.design.widget.CoordinatorLayout
xmlns:android="http://schemas.android.com/apk/res/android"
xmlns:app="http://schemas.android.com/apk/res-auto"
xmlns:tools="http://schemas.android.com/tools"
android:layout_width="match_parent"
android:layout_height="match_parent"
tools:context=".activities.MonthViewActivity"> // Changed here
<ImageView
android:id="@+id/month_view_prev_month"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:src="@drawable/ic_keyboard_arrow_left_black_24dp"
android:onClick="changeMonth"/>
</android.support.design.widget.CoordinatorLayout>
Changing the tools:context
to the class of the calling activity fixed the error for me.
You can try this to solve the issue
XML in .MainActivity
<TextView
android:id="@+id/numbers"
style="@style/CategoryStyle"
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:background="@color/category_numbers"
android:text="@string/category_numbers"
android:onClick="openNumberList"/>
Java Code
public class MainActivity extends AppCompatActivity {
@Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);
}
public void openNumberList(View view) {
Intent i = new Intent(this, NumberActivity.class);
startActivity(i);
}
}
declare a method in MainActivity with the name of openNumberList
. You don't need to define it in NumberActitvity
