當設置計數器以減去並關閉應用程序時,出現錯誤。我收到一個錯誤「無法將值賦給最終變量計數器」。如果用戶登錄3次而沒有成功退出應用程序。如何在android studio中添加計數器以退出應用程序
final int counter = 3;
//Set the OKButton to accept onClick
OKButton.setOnClickListener(new View.OnClickListener() {
@Override
//once onClick is initalized it takes user to page menu
public void onClick(View v) {
//display text that was inputed for userText and passText
user = userText.getText().toString();
pass = passText.getText().toString();
//create if loop which checks if user and pass equals the credentials
if (user.equals("pshivam") && pass.equals("Bway.857661")) {
//display toast access welcome
String welcome = "Access Granted.";
//Create a Toast to display the welcome string in the MainActivity.
Toast.makeText(MainActivity.this, welcome, Toast.LENGTH_SHORT).show();
setContentView(R.layout.account_main);
}
//create else if loop which checks if user or pass does not equals the credentials
else if (!user.equals("pshivam") || !pass.equals("Bway.857661")){
//displays previous entry
userText.setText(user);
passText.setText(pass);
//allows user to re-enter credentials.
user = userText.getText().toString();
pass = passText.getText().toString();
//display toast access fail
String fail = "Access Denied! Please Try again.";
//Create a Toast to display the fail string in the MainActivity.
Toast.makeText(MainActivity.this, fail, Toast.LENGTH_SHORT).show();
counter--;
if(counter == 0){
finish();
}
}
}
});
}
}
你不能改變最終變量的值 – uptoNoGood
