在edittext中为setText值引发错误。 Id给定是正确的,如果我给set尝试在空对象引用上调用虚拟方法'void android.widget.EditText.setText(java.lang.CharSequence)'导致空指针异常
下面给出的代码我不能setText Otp代码“ otpcode.setText( “12345”);”在创造它完美的作品。 当我给它的方法“recivedSms”,它没有工作。
public class Change_Password_Activity extends AppCompatActivity {
EditText user_name,pass_wd;
public EditText otpcode;
private Button btn_submit;
private String username,otp,password;
private ProgressDialog prgDialog;
private Typeface typeface;
@Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_change__password_);
typeface = GlobalVariables.getTypeface(Change_Password_Activity.this);
prgDialog = new ProgressDialog(this);
// Set Progress Dialog Text
prgDialog.setMessage("Please wait...");
// Set Cancelable as False
prgDialog.setCancelable(false);
otpcode = (EditText)findViewById(R.id.otpedittext);
user_name = (EditText) findViewById(R.id.edittext_ch_user);
pass_wd = (EditText) findViewById(R.id.edittext_ch_passwd);
btn_submit = (Button) findViewById(R.id.button_changepswd);
otpcode.setTypeface(typeface);
user_name.setTypeface(typeface);
pass_wd.setTypeface(typeface);
btn_submit.setTypeface(typeface);
}
public void recivedSms(String message)
{
try
{
int smsnumbr= Integer.parseInt(message);
otpcode.setText(smsnumbr);
}
catch (Exception e)
{
Log.e("error", String.valueOf(e));
}
是否onCreate总是在receivedSms之前调用? –
何时何地receivedSms叫? – zgc7009
收到短信方法onCreate后调用 – susaine
