Hi !
The problem is I don't success to take the variable from other classes. I
did like this :
In Cau_1_grammar.java :
private RadioButton a;
private RadioButton b;
private RadioButton c;
private RadioButton d;
static char Cau_1_Answer;
public static char getCau_1_Answer() {
return Cau_1_Answer;
}
public static void setCau_1_Answer(char cau_1_Answer) {
Cau_1_Answer = cau_1_Answer;
}
@Override
protected void onCreate(Bundle icicle)
{
super.onCreate(icicle);
setContentView(R.layout.cau_1_grammar);
a = (RadioButton)this.findViewById(R.id.cau_1_a_grammar);
b = (RadioButton)this.findViewById(R.id.cau_1_b_grammar);
c = (RadioButton)this.findViewById(R.id.cau_1_c_grammar);
d = (RadioButton)this.findViewById(R.id.cau_1_d_grammar);
if (a.isChecked()) {this.setCau_1_Answer('a');}
if (b.isChecked()) {this.setCau_1_Answer('b');}
if (c.isChecked()) {this.setCau_1_Answer('c');}
if (d.isChecked()) {this.setCau_1_Answer('d');}
......
In Resume_grammar.java :
char[] AnswerList = new char[10];
....
AnswerList[0] = Cau_1_grammar.getCau_1_Answer();
The AnswerList[0] doesn't take a,b,c or d but nothing if I use
AnswerTextView[1].setText(Character.toString(AnswerList[1]));
and 0 if I use AnswerTextView[1].setText(Integer.toString(AnswerList[1]));
I am ok with Android part but not java, please help. Thank you !
Dan, Megha.., could you help me ?
Tung.
