android - First activity won't run on AVD -

I made an application, my first, and I'm having trouble walking on Aveedi. Will not load the first activity, simply say "Unfortunately, FussyFestivalrV7 The main initial activity is stopped:

  Package com.example.fussyfestivalr; Import android App Import android.content.Intent; Importroid.os.Bundle; Import android.view.View; Import android.widget.Button; Public Square MainActivity Extension Activity {@Override Public Zero OnCreate (bundled savedInstanceState) {super.onCreate (savedInstanceState); SetContentView (R.layout.activity_main); Button switch button = (button) VVBIID (R.B. button 1); switchButton.setOnClickListener (New View.OnClickListener () {@Override see public void onClick (v) {Intent intent = new Intent (MainActivity.this, News.class); startActivity (intent);}}); }}  

and my layout

  & lt; RelativeLayout xmlns: android = "http://schemas.android.com/apk/res/android" xmlns: device = "http://schemas.android.com/tools" Android: layout_width = "match_parent" Android: layout_height = "Match_parent" Android: background = "@ string / title" tool: reference = "$ {} relativePackage. $ {Action class}" & gt; & Lt; TextView android: id = "@ + id / title" Android: Layout_width = "Wrap_content" Android: Layout_height = "Wrap_content" Android: layout_alignParentTop = "true" Android: layout_centerHorizontal = "true" android: text = "@ string / Title" Android: Text Appointment = "?
