Create an android project for the following problem.

You are tasked to create an Android project that will compute for the Semestral Grade for students. The following are the requirements of the said project; Student Id Number, Name of Student, Course, Year Level, Assignment (10%), Quizzes (40%), Recitation (10%) and Exam (40%). Compute the grade by adding the assignment, quizzes, recitation and exams.

As you can see the photo above, the user can input the first requirements such as ID Number, Name of student, Course, Year level. The second one is for Assignments, Quizzes, Recitation and Exams. The first EditText (left side) indicates the SCORE of the student which is divided by the TOTAL number of the said requirement. (right side).

Once you completed to filed up. Click the “Compute” button for the results which is separated/ in other XML file. See the photo below. 🙂

PS: you can design your own XML if you want. But I’ll post the java code for this.. 😀

For JAVA

import android.app.Activity;
import android.os.Bundle;
import android.text.Html;
import android.view.View;
import android.widget.Button;
import android.widget.EditText;
import android.widget.TextView;

public class LabExam extends Activity {
    /** Called when the activity is first created. */
    @Override
    public void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.main);
        
        /*
        Button backButton = (Button) findViewById(R.id.backButton);
        backButton.setOnClickListener(new View.OnClickListener() {
			
			public void onClick(View arg0) {

				setContentView(R.layout.main);

		});*/
        
        
        final Button button = (Button) findViewById(R.id.button1);
        button.setOnClickListener(new View.OnClickListener() {

float scoreAssign = Integer.parseInt(scoreAssignText.getText().toString());
float totalAssign = Integer.parseInt(totalAssignText.getText().toString());

				resultText.setText(
						Html.fromHtml(

    }
}

 

Hope you have a beautiful day~
