Android: Intent不从mainactivity获取数据

Question

我有2个活动，从第二个Activity的OnCreate我这样做:

setPassButton.setOnClickListener(new View.OnClickListener() {
@Override
public void onClick(View v) {
            if(getPass1 == getPass2) {
                Intent gotoMain = new Intent(FirstRun.this, MainActivity.class);
                gotoMain.putExtra("getPass1", getPass1);
                startActivity(gotoMain);

在第一个Activity中，我试图获取这个getPass1，但它总是给我-1。我遗漏了什么?这也在MainActivity

的OnCreate中

Intent intent = getIntent();
iSelectedItem = intent.getIntExtra("getPass1", -1);
System.out.println("Password is " + iSelectedItem);

Answer 1

试试这个:

Intent intent = getIntent();
iSelectedItem = intent.getExtras().getInt("getPass1", -1);
System.out.println("Password is " + iSelectedItem);
