I am having an activity and a layout for it .I have included a view in this layout which is common in all activities for showing error message.This common view is working fine in all of the activities but in one activity findviewby id is giving null for this view.Have tried a lot but not able to track where the problem is.Please see the code if anyone can suggest me something.Here is the code
Activity:
public class VerificationCodeActivity extends Activity {
TextView resend_code,other_numbers;
EditText vc_code1,vc_code2,vc_code3,vc_code4;
Button verify_code;
RelativeLayout error_layout;
TextView error_textview;
Button close_error_button;
Context ctx =this;
String confirmCode;
Bundle bundle;
String usernumber,countrycode,tempid;
ArrayList<String>other_numebr_list;
String accessType;
@Override
protected void onCreate(Bundle arg0) {
// TODO Auto-generated method stub
setContentView(R.layout.verification_code_layout);
init();
super.onCreate(arg0);
}
void init()
{
resend_code = (TextView)findViewById(R.id.vc_resend_button);
resend_code.setPaintFlags(resend_code.getPaintFlags() | Paint.UNDERLINE_TEXT_FLAG);
error_textview = (TextView)findViewById(R.id.error_text);
//here is the layout
error_layout=(RelativeLayout)findViewById(R.id.error_layout);
close_error_button= (Button)findViewById(R.id.close_button);
}
}
void showErrorMessage(Boolean showm,String message )
{
if(showm)
{
error_textview.setText(message);
CommonUtility.expand(error_layout);
}
else{
CommonUtility.collapse(error_layout);
}
}
}
