copied!<p>I already tried these set of codes:</p> <pre><code>radioButton.setEnabled(false); radioButton.setClickable(false); </code></pre> <p>but it didn't work for me because when I tried to go back again to the activity with radio buttons, it will be clickable again.</p> <p>What I want is that when I click it once , it will not be clickable again even if I tried to go back to the activity.</p> <p>These were the codes of my activity</p> <pre><code>public class TeacherSideQuestion extends Activity { @Override protected void onCreate(Bundle savedInstanceState) { // TODO Auto-generated method stub super.onCreate(savedInstanceState); setContentView(R.layout.question1); Button btnNext = (Button) findViewById(R.id.btnNext); Button btnCheck = (Button) findViewById(R.id.btnCheckTeacher1); btnNext.setOnClickListener(new OnClickListener() { @Override public void onClick(View v) { // TODO Auto-generated method stub Intent intent = new Intent(v.getContext(), TeacherSideQuestion2.class); startActivityForResult(intent, 0); } }); btnCheck.setOnClickListener(new OnClickListener() { @Override public void onClick(View v) { // TODO Auto-generated method stub SharedPreferences my_preferences = PreferenceManager .getDefaultSharedPreferences(getApplication()); SharedPreferences.Editor editor = my_preferences.edit(); RadioButton rbtnTeacher1_1 = (RadioButton) findViewById(R.id.rbtnTeacher1_1); RadioButton rbtnTeacher1_2 = (RadioButton) findViewById(R.id.rbtnTeacher1_2); RadioButton rbtnTeacher1_3 = (RadioButton) findViewById(R.id.rbtnTeacher1_3); if (rbtnTeacher1_1.isChecked()) { Toast.makeText(TeacherSideQuestion.this, "Correct", Toast.LENGTH_SHORT).show(); rbtnTeacher1_1.setClickable(false); rbtnTeacher1_2.setClickable(false); rbtnTeacher1_3.setClickable(false); if (rbtnTeacher1_1.isChecked()) { editor.putInt("key1", 1); } else { editor.putInt("key1", 0); } editor.commit(); } else if (rbtnTeacher1_2.isChecked()) { Toast.makeText(TeacherSideQuestion.this, "Incorrect", Toast.LENGTH_SHORT).show(); rbtnTeacher1_1.setTextColor(Color.RED); rbtnTeacher1_1.setClickable(false); rbtnTeacher1_2.setClickable(false); rbtnTeacher1_3.setClickable(false); if (rbtnTeacher1_2.isChecked()) { editor.putInt("key1", 0); } editor.commit(); } else if (rbtnTeacher1_3.isChecked()) { Toast.makeText(TeacherSideQuestion.this, "Incorrect", Toast.LENGTH_SHORT).show(); rbtnTeacher1_1.setTextColor(Color.RED); rbtnTeacher1_1.setClickable(false); rbtnTeacher1_2.setClickable(false); rbtnTeacher1_3.setClickable(false); if (rbtnTeacher1_3.isChecked()) { editor.putInt("key1", 0); } editor.commit(); } else { return; } } }); } } </code></pre>
