如何切换意图功能取决于活动

Question

如何根据父活动切换函数?我有两种情况，我想在函数之间切换。我的功能与短信otp验证有关。

1。当用户注册时，功能是验证otp并激活用户。

case2:当用户忘记密码时，他们会生成一个新的otp来重置密码。

这是我的函数代码

@Override
protected void onHandleIntent(Intent intent) {
    // SqLite database handler
    db = new SQLiteHandler(getApplicationContext());
    // Fetching user details from sqlite
    HashMap<String, String> user = db.getUserDetails();

    if (intent != null) {
        String otp = intent.getStringExtra("otp");
        String phone = user.get("phone");
        verifyOtp(otp,phone);
    }
}

现在我想把它变成

    @Override
    protected void onHandleIntent(Intent intent) {
        // SqLite database handler
        db = new SQLiteHandler(getApplicationContext());
        // Fetching user details from sqlite
        HashMap<String, String> user = db.getUserDetails();

  if (intent != null) {
      String otp = intent.getStringExtra("otp"); //this coming from sms receiver 
    //from here i want to switch if parent activity is register activity below function should run

  String phone = user.get("phone");
  verifyOtp(otp,phone);

    // if parent activity  if forgot password activity the below function should run
    String phone = session.getmobileno();
    verifyfpass(otp,phone)
  }
}

Answer 1

如果你说的父activity是指启动intent的地方，那么你可以在intent中添加另一个参数来告诉intent是从哪里发送的

Intent intent = new Intent(this, NextActivity.class);
intent.putExtra("from", "RegisterActivity");
startActivity(intent);

然后在handleIntent函数中，你可以检查这个变量的值，并执行你的函数，如

if (intent.hasExtra("from")) {
     String from = intent.getStringExtra("from");
     if (from.equals("RegisterActivity")) {
           //verifyotp
     } else if (from.equals("ForgotParentActivity")) {
          //verifyfpass
     }
}

然而，如果你想检查你现在所处的活动，那么你可以使用instanceof属性。

if (this instanceof RegisterActivity) {
     //verifyotp
} else if (this instanceof ForgotParentActivity)) {
     //verifyfpass
}

Answer 2

在家长活动

Intent intent = new Intent(this, NextActivity.class);
intent.putExtra("from", "RegisterActivity");
startActivity(intent);

最终答案主要活动@OverrideonHandleIntent(Intent Intent) {

        pref = new SessionManager(getApplicationContext());
        // SqLite database handler
        db = new SQLiteHandler(getApplicationContext());
        // Fetching user details from sqlite
        HashMap<String, String> user = db.getUserDetails();
        if (intent != null) {
            if (intent.hasExtra("from")) {
                String from = intent.getStringExtra("from");
                if (from.equals("RegisterActivity")) {
                    String otp = intent.getStringExtra("otp");
                    String phone = user.get("phone");
                    verifyOtp(otp, phone);
                } else if (from.equals("Forgotpass")) {
                    String otp = intent.getStringExtra("otp");
                    String phone = pref.getMobileNumber();
                    verifyfpass(otp,phone);
                }

            }

        }
    }
