setContentView(R.layout.activity_main);
}
public void theFirst() {
String answer1 = "David Ben Gurion";
EditText text = (EditText) findViewById(R.id.answer_no_1);
text.getText().toString();
if (text.equals(answer1)) {
Context context = getApplicationContext();
CharSequence text1 = "Right";
int duration = Toast.LENGTH_SHORT;
Toast rightToast = Toast.makeText(context, text1, duration);
rightToast.show();
}else {
