这是我的代码。在这段代码中，我试图在第一次单击按钮时更改四个文本的内容，在单击同一个按钮时，我试图更改仅三个文本视图的内容。但它不起作用。
public class Home_page_Activity extends Activity {
Button next;
int textids[]={R.id.text1,R.id.text2,R.id.text3,R.id.text4};
String Question[]={"1","2","3","4"};
String three[]={"7","27","37"};
TextView t1,t2,t3,t4,t5,t6,t7;
int count=0;
int check=0;
//int button_id[]={R.id.next};
//Button btn[];
int test=0;
@Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_home_page_);
t1=(TextView)findViewById(R.id.text1);
t2=(TextView)findViewById(R.id.text2);
t3=(TextView)findViewById(R.id.text3);
t4=(TextView)findViewById(R.id.text4);
t5=(TextView)findViewById(R.id.text5);
t6=(TextView)findViewById(R.id.text6);
t7=(TextView)findViewById(R.id.text7);
next=(Button)findViewById(R.id.next);
next.setOnClickListener(new OnClickListener() {
@Override
public void onClick(View v) {
// TODO Auto-generated method stub
if(test==1)
{
String get=(String) t1.getText();
//int inter=Integer.parseInt(get);
Log.i("t1", get);
t1.setText("");
t2.setText("");
t3.setText("");
t4.setText("");
threetext();
}
nextquestion();
}
});
}
public void nextquestion()
{
t1.setText(Question[count]);
t2.setText(Question[count+1]);
t3.setText(Question[count+2]);
t4.setText(Question[count+3]);
Log.i("count", "value" +count);
test++;
}
public void threetext()
{
Log.i("threetext", "working");
t1.setText(three[check]);
t2.setText(three[check+1]);
t3.setText(three[check+2]);
t4.setText("");
}
