First Sprint stage time: 11.17~11.27

This procedure is to solve the problem of last judgment, but there is a new problem page can not be adjusted, need to be improved

This improvement code is:

Import Java.util.random;import android.os.bundle;import Android.app.activity;import Android.view.menu;import Android.view.view;import Android.view.view.onclicklistener;import Android.widget.button;import Android.widget.edittext;import Android.widget.textview;import Android.widget.toast;public class CalculatorActivity Extends Activity {Private final random num1=new random ();p rivate final random num2=new random ();p rivate final random r = N EW Random ();p rivate char[] ch = {' + ', '-', ' * ', '/'}; Character array private int index = R.nextint (ch.length); Random number, less than the length of the array, 0~3private Char A=ch[index];p rivate TextView text1,text2,text3;private EditText answer;private Button surebutton;//OK button private string c;private string e;private string b;private int i1,i2,i3; @Overrideprotected void OnCreate (Bundle savedinstancestate) {super.oncreate (savedinstancestate); Setcontentview (r.layout.activity_ Calculator); text1= (TextView) Findviewbyid (R.ID.TEXTVIEW1);//random number text2= (TextView) Findviewbyid (R.ID.TEXTVIEW2);// Op symbol text3= (TexTView) Findviewbyid (R.ID.TEXTVIEW3);//random number answer= (EditText) Findviewbyid (R.ID.EDITTEXT1);//Results B=answer.gettext ( ). toString ();//Gets the input value i1=integer.valueof (b); c=string.valueof (Num1.nextint); i1=integer.valueof (c); String d=string.valueof (a); e=string.valueof (Num2.nextint); i3=integer.valueof (e); Text1.settext (c);// Random number 1-100text2.settext (d);//random operator +,-, *,/text3.settext (e);//random number 1-100surebutton= (Button) Findviewbyid ( R.id.surebutton);//OK button Surebutton.setonclicklistener (new Onclicklistener () {@Overridepublic void OnClick (View arg0) {//TODO auto-generated Method Stubswitch (Index) {case 0:{if (I1==I2+I3) toast.maketext (calculatoractivity.this, "correct" +b , Toast.length_short).

Show (); Break;}}});} @Overridepublic boolean Oncreateoptionsmenu (Menu menu) {//Inflate the menu; This adds items to the action bar if it is PR Esent.getmenuinflater (). Inflate (R.menu.calculator, menu); return true;}}

Failure, is trying to improve in!
