Android Studio sharedpreferences不工作另一个活动

Question

我已经创建了两个活动注册和登录。此外，我有SharedPreferences获得edittext值。当我调用SharedPreferences(getNomre))内部onCreate它工作，但不工作作为全局变量。我想声明一个名为mobileNomre的变量，以便对Constant.mobile使用put。如何将共享偏好值发送到Constant.mobile?

p。活动代码太大。我注意到了其中的一些部分。由于

SignUpActivity:

public void SignUpWithEmail(View view) {
if (!validateForm()) {
return;
}
showProgressDialog();
final String email = edtEmail.getText().toString();
final String password = edtPassword.getText().toString();
final String name = edtName.getText().toString();
final String mobile = edtMobile.getText().toString();

Session.setNomre(getApplicationContext(),"nomreler",mobile);

FirebaseUser user = FirebaseAuth.getInstance().getCurrentUser();
UserProfileChangeRequest profileUpdates = new UserProfileChangeRequest.Builder()
.setDisplayName(name).build();
assert user != null;
user.updateProfile(profileUpdates)
.addOnCompleteListener(new OnCompleteListener<Void>() {
@Override
public void onComplete(@NonNull Task<Void> task) {
if (task.isSuccessful()) {
}
}
});
sendEmailVerification();
} else {
hideProgressDialog();
try {
throw Objects.requireNonNull(task.getException());
} catch (FirebaseAuthInvalidCredentialsException | FirebaseAuthInvalidUserException | FirebaseAuthUserCollisionException invalidEmail) {
inputEmail.setError(invalidEmail.getMessage());
} catch (Exception e) {
e.printStackTrace();
inputEmail.setError(e.getMessage());
}
}
}
});
}

LoginActivity:

public class LoginActivity extends AppCompatActivity {
String TAG = "LoginActivity";
int RC_SIGN_IN = 9001;
CallbackManager mCallbackManager;
String token;

String mobileNomre = Session.getNomre(getApplicationContext(),"nomreler","");

public static FirebaseAuth mAuth;
GoogleSignInClient mGoogleSignInClient;
TextView tvPrivacy, tvTest;
ProgressDialog mProgressDialog;
public TextInputEditText edtEmail, edtPassword;
public TextInputLayout inputEmail, inputPass;

public void UserSignUpWithSocialMedia(   final String mobileNomre,
final String fCode,
final String referCode,
final String name,
final String email,
final String profile,
final String type) {

StringRequest strReq = new StringRequest(Request.Method.POST, Constant.QUIZ_URL, new Response.Listener<String>() {
@Override
public void onResponse(String response) {
try {

JSONObject obj = new JSONObject(response);
if (obj.getString("error").equals("false")) {
JSONObject jsonobj = obj.getJSONObject("data");
if (!jsonobj.getString(Constant.status).equals(Constant.DE_ACTIVE)) {
Session.saveUserDetail(getApplicationContext(),
jsonobj.getString(Constant.userId),
jsonobj.getString(Constant.name),
jsonobj.getString(Constant.email),
jsonobj.getString(Constant.mobile),
jsonobj.getString(Constant.PROFILE), referCode);

User user = new User(
jsonobj.getString(Constant.mobile),
jsonobj.getString(Constant.name),
jsonobj.getString(Constant.email),
"0",
false,
jsonobj.getString(Constant.PROFILE),
"0",
token,
jsonobj.getString(Constant.userId));

FirebaseDatabase.getInstance().getReference("user").child(FirebaseAuth.getInstance().
getCurrentUser().getUid()).setValue(user).
addOnCompleteListener(new OnCompleteListener<Void>() {
@Override
public void onComplete(@NonNull Task<Void> task1) {
Intent i = new Intent(getApplicationContext(), MainActivity.class);
i.putExtra("type", "default");
i.setFlags(Intent.FLAG_ACTIVITY_NEW_TASK | Intent.FLAG_ACTIVITY_CLEAR_TASK);
startActivity(i);
finish();
}
});
hideProgressDialog();
} else
setSnackBarStatus();
} else {
LoginManager.getInstance().logOut();
Toast.makeText(getApplicationContext(), obj.getString("message"), Toast.LENGTH_LONG).show();
}
} catch (JSONException e) {
e.printStackTrace();
}
}
}, new Response.ErrorListener() {
@Override
public void onErrorResponse(VolleyError error) {
}
}) {

@Override
protected Map<String, String> getParams() {
Map<String, String> params = new HashMap<String, String>();
params.put(Constant.accessKey, Constant.accessKeyValue);
params.put(Constant.userSignUp, "1");
params.put(Constant.email, email);
params.put(Constant.name, name);
params.put(Constant.PROFILE, profile);
params.put(Constant.fcmId, token);
params.put(Constant.type, type);
params.put(Constant.mobile, mobileNomre );
params.put(Constant.REFER_CODE, referCode);
params.put(Constant.FRIENDS_CODE, fCode);
WifiManager wm = (WifiManager) getApplicationContext().getSystemService(WIFI_SERVICE);
String ip = Formatter.formatIpAddress(wm.getConnectionInfo().getIpAddress());
params.put(Constant.ipAddress, ip);
System.out.println("---params social  " + params.toString());
return params;
}
};
// AppController.getInstance().getRequestQueue().getCache().clear();
AppController.getInstance().addToRequestQueue(strReq);
}

SharedPrereferences:

public class Session {
public static void setNomre(Context mContext, String key, String objString) {
SharedPreferences.Editor editor =
mContext.getSharedPreferences(mContext.getString(R.string.app_name),
Context.MODE_PRIVATE).edit();
editor.putString(key, objString);
editor.commit();
}
public static String getNomre(Context mContext, final String key, final String defaultStr) {
SharedPreferences pref = mContext.getSharedPreferences(mContext.getString(R.string.app_name),
Context.MODE_PRIVATE);
return pref.getString(key, defaultStr);
}}

Answer 1

让您的字符串public static全局访问;

public static String mobileNomre = Session.getNomre(getApplicationContext(),"nomreler","");

没有尝试过，但工作周围与下面的代码可以给你一个想法，如果我们想访问Activity2中Activity1的任何函数，我们使用这个方法。

AnotherActivity anotheractivity = (AnotherActivity) this.getActivity();
