Question

I am new to this Quiz Applications.

I am using radio buttons here. When I click on wrong options it will come on red color and it has to display correct answer also. Now here is my code. When i click on the next button it will appear like this. Thanks in advance. here total, correct and wrong are static variables to display the final score in another class.

            RadioButton uans = (RadioButton) findViewById(rg.getCheckedRadioButtonId());
            String ansText = uans.getText().toString();

            if (ansText.equalsIgnoreCase(answers[flag])) {


                correct++;
            } else {



                wrong++;
            }
            flag++;

            if (flag < question.length) {
                tv.setText(question[flag]);
                rb1.setText(options[flag * 3]);
                rb2.setText(options[flag * 3 + 1]);
                rb3.setText(options[flag * 3 + 2]);
                marks = correct - wrong;

            } else {
                marks = correct - wrong;
                Intent in = new Intent(getApplicationContext(),
                        ResultActivity.class);
                startActivity(in);

            }
            if (flag == question.length) {
                Intent in = new Intent(getApplicationContext(),
                        ResultActivity.class);
                startActivity(in);
                Level1Activity.this.finish();
            }
            total = question.length;

Answer 1

add these statement where you find a wrong ans, that is in else part, where you need to set a red color.

if your color.xml is like:

<color name="errorColor">#f00</color>

then

uans.setTextColor(getResources().getColor(R.color.red));

and also set the ans with another color
