Thank you,Geoffrey !
Exactly, I change to
AnswerTextView[0] = (TextView)findViewById(R.id.cau_1_answer_grammar);
it works well.
But all my AnswerList displays 0 while I set all *char*, please see brief
code, I think the last instruction has problem, but don't know how to fix :
char[] AnswerList = new char[10];
protected void onCreate(Bundle icicle){
super.onCreate(icicle);
setContentView(R.layout.result_grammar);
setAnswerList();
setAnswerListTextView();
}
private void setAnswerList() {
//assign AnswerList[10]
AnswerList[0] = Cau_1_grammar.getCau_1_Answer();
AnswerList[1] = Cau_2_grammar.getCau_2_Answer();
AnswerList[2] = Cau_3_grammar.getCau_3_Answer();
AnswerList[3] = Cau_4_grammar.getCau_4_Answer();
AnswerList[4] = Cau_5_grammar.getCau_5_Answer();
AnswerList[5] = Cau_6_grammar.getCau_6_Answer();
AnswerList[6] = Cau_7_grammar.getCau_7_Answer();
AnswerList[7] = Cau_8_grammar.getCau_8_Answer();
AnswerList[8] = Cau_9_grammar.getCau_9_Answer();
AnswerList[9] = Cau_10_grammar.getCau_10_Answer();
}
protected void setAnswerListTextView() {
// Identify TextView on "Your answer:" column
AnswerTextView[0]=(TextView)this.findViewById(R.id.cau_1_answer_grammar);
AnswerTextView[1]=(TextView)this.findViewById(R.id.cau_2_answer_grammar);
AnswerTextView[2]=(TextView)this.findViewById(R.id.cau_3_answer_grammar);
AnswerTextView[3]=(TextView)this.findViewById(R.id.cau_4_answer_grammar);
AnswerTextView[4]=(TextView)this.findViewById(R.id.cau_5_answer_grammar);
AnswerTextView[5]=(TextView)this.findViewById(R.id.cau_6_answer_grammar);
AnswerTextView[6]=(TextView)this.findViewById(R.id.cau_7_answer_grammar);
AnswerTextView[7]=(TextView)this.findViewById(R.id.cau_8_answer_grammar);
AnswerTextView[8]=(TextView)this.findViewById(R.id.cau_9_answer_grammar);
AnswerTextView[9]=(TextView)this.findViewById(R.id.cau_10_answer_grammar);
// Display answer in "Your answer:" column
for(int i=0;i<=9;i++){
AnswerTextView[i].setText(Integer.toString(AnswerList[i]));
// *Does
this drive all char to 0*
}
}
