Error with the if and else statement

Error with the if and else statement - android

I am getting 3 different errors: identifier expected, unexpected token, unknown class: 'score'. These error's are in line 57-69.
The point of this code is to check if a checklist is checked and, if so, add 1 to score. It than changes the output text to a different string depending on score.

You have the closing curly bracket } in the wrong place. The function was ending before the if.

Checklist log error

There is an error in my code, that I don't understand, where when a checkbox is ticked the application closes.
A brief summary of what I'm trying to do. When the check button is pressed, it tries to see what checklists have been checked and than add 1 to score if it is checked. I than to output text depending on the score received.
If there are any other mistakes I've made please point them out. Also include code example(Makes it easier to understand).

^^ pop up xml code^^

You should set your launcher in your manifest as check_Button instead of the default, which is probably Pop_sallian.
<activity
android:name=".check_Button"
<!--stuff -->
<intent-filter>
<action android:name="android.intent.action.MAIN" />
<category android:name="android.intent.category.LAUNCHER" />
</intent-filter>
</activity>

Setting an event for a button

I've asked a question similar to this. The point of this code is to check if a checklist is checked, if it is than it adds 1 to the score.
I've been told that the problem is that I haven't set an event. Please explain what I need to do to make it work, I'm new to android development and have been stuck on this for a few days. Please give a code example with your answer.

^^ xml code the code takes for^^

You are defining a checked listener, but doing nothing with it. You need to set it to your checkbox or checkboxes.
mCheckBox = (CheckBox) findViewById(R.id.concern);
mCheckBox.setOnCheckedChangedListener(checkedListener);
Just like you do on your buttons.

Button is being disabled after clicking once.I want to reuse it

In a part of my program There is a button named "imageButton_sound"in xml file "activity_exam_class_1".I want to play a sound clicking this button.First when i click it, it play sound but from the second time it doesn't work.
I initialize this xml file in"Exam_class_1.java" file .
The sequence of my program is -first I will press the"imageButton_sound" then press any other button of the same file like "imageButton_a","imageButton_b""imageButton_c"...........etc.
Then after fulfilling some condition the program will go to either "success_exam.xml" or "fail_exam.xml"
file both of which contain a button .After pressing the button it will go back to the "activity_exam_class_1",and then I will press"imageButton_sound"again and the process will be continued .
here are my code :
Exam_class_1.java:

slm;I think you should RE-Initialise the counter "int Ks=0;"at the end of your first part of game. try to "RE-Initialise" like this:
else{
if((opt == R.id.imageButton_a && ks==1)||(opt == R.id.imageButton_b && ks==2)||
(opt == R.id.imageButton_c && ks==3)||(opt == R.id.imageButton_d && ks==4)||
(opt == R.id.imageButton_e && ks==5)||(opt == R.id.imageButton_f && ks==6)){
Ks=0;
setContentView(R.layout.success_exam1);
joy_sound = MediaPlayer.create(this,R.raw.joy);
joy_sound.start();
}
else{ Ks=0;
setContentView(R.layout.fail_exam1);
wrong_sound = MediaPlayer.create(this,R.raw.wrong);
wrong_sound.start();
}

Your Bksp method is not implemented in your xml file.

Your code is horrible (one method per number?), looking your insert method you should do some edits.
private void insert(int j) {
//Insert the values by clicking button
str = str+Integer.toString(j);
num = Integer.valueOf(str).intValue();
showResult.setText(str);
}
First:
You should use Double.* methods because Integer cannot have float values.
I don't see any code which do the math so you should do the edits.
Then, to make the dot method you could just do it
private void insert() {
//Insert the values by clicking button
str = str+".0";
num = Double.valueOf(str);
showResult.setText(str);
}
It's what you should do to support dot.
Anyway, you can get remove .intValue() from Integer.valueOf(str).intValue()
