当我尝试切换到我的应用程序中的某个活动时，它崩溃。这是我在手机上运行时的logcat。当试图运行新活动时意外崩溃的Android应用程序
下面是我从开始的活动：
package com.epicodus.parkr;
import android.app.ProgressDialog;
import android.content.Intent;
import android.graphics.Typeface;
import android.support.annotation.NonNull;
import android.support.v7.app.AppCompatActivity;
import android.os.Bundle;
import android.util.Log;
import android.view.View;
import android.widget.Button;

import android.widget.TextView;
import android.widget.Toast;
import com.google.android.gms.tasks.OnCompleteListener;
import com.google.android.gms.tasks.Task;
import com.google.firebase.auth.AuthResult;
import com.google.firebase.auth.FirebaseAuth;
import com.google.firebase.auth.FirebaseUser;
import butterknife.Bind;
import butterknife.ButterKnife;
public class MainActivity extends AppCompatActivity implements V View.OnClickListener {
private FirebaseAuth mAuth;
private ProgressDialog mSignInProgressDialog;
@Bind(R.id.headline)TextView mHeadline;
@Bind(R.id.headline2) TextView mHeadline2;
@Bind(R.id.signUpButton)Button mSignUpButton;
@Bind(R.id.loginButton) Button mLoginButton;
@Bind(R.id.emailInput) EditText mEmailInput;
@Bind(R.id.passwordInput) EditText mPasswordInput;
@Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);
// createSignInProgressDialog();
mAuth = FirebaseAuth.getInstance();
ButterKnife.bind(this);
Typeface newFont = Typeface.createFromAsset(getAssets(), "fonts/Lobster-Regular.ttf");
mHeadline.setTypeface(newFont);
mHeadline2.setTypeface(newFont);
mSignUpButton.setOnClickListener(this);
mLoginButton.setOnClickListener(this);
}
@Override
public void onClick(View v){
if(v == mSignUpButton){
Intent signUpIntent = new Intent (MainActivity.this, SignUpActivity.class);
startActivity(signUpIntent);
}else if(v == mLoginButton){
// mSignInProgressDialog.show();
login();
finish();
}
}
private void login(){
final String email = mEmailInput.getText().toString();
final String pass = mPasswordInput.getText().toString();
if(!isNotEmpty(email) || !isNotEmpty(pass)) return;
mAuth.signInWithEmailAndPassword(email, mPasswordInput.getText().toString())
.addOnCompleteListener(this, new OnCompleteListener<AuthResult>() {
@Override
public void onComplete(@NonNull Task<AuthResult> task) {
if (task.isSuccessful()) {
// mSignInProgressDialog.dismiss();
Intent loginIntent = new Intent (MainActivity.this, AccountActivity.class);
startActivity(loginIntent);
finish();
} else if (!task.isSuccessful()){
Toast.makeText(MainActivity.this, "Please Try Again", Toast.LENGTH_SHORT).show();
finish();
}
}
});
}
private void createSignInProgressDialog() {
mSignInProgressDialog = new ProgressDialog(this);
mSignInProgressDialog.setTitle("Loading...");
mSignInProgressDialog.setMessage("Signing In...");
mSignInProgressDialog.setCancelable(false);
}
private Boolean isNotEmpty(String email){
if(email.equals("")){
mEmailInput.setError("Blank Field");
return false;
}
return true;
}
}
这里是我想移动到活动：

@Override

mAuth = FirebaseAuth.getInstance();
uid = mAuth.getCurrentUser().getUid();
mSpecificUserReference = FirebaseDatabase.getInstance().getReference().child(Constants.FIREBASE_CHILD_USER).child(uid);
mSpecificUserReference.addValueEventListener(new ValueEventListener() {
@Override
public void onDataChange(DataSnapshot dataSnapshot) {
String userName = dataSnapshot.child("fullName").getValue().toString();
mUserNameDisplay.setText(userName);
}
@Override
public void onCancelled(DatabaseError databaseError) {
}
});
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_account);
ButterKnife.bind(this);
Typeface newFont = Typeface.createFromAsset(getAssets(), "fonts/Lobster-Regular.ttf");
mHeadline.setTypeface(newFont);
Intent infoIntent = getIntent();
String userName = infoIntent.getStringExtra("user");
mUserNameDisplay.setText(userName);
mFindSpotsButton.setOnClickListener(this);
mLogOutButton.setOnClickListener(this);
}
private void logout() {
FirebaseAuth.getInstance().signOut();
Intent intent = new Intent(AccountActivity.this, MainActivity.class);
intent.setFlags(Intent.FLAG_ACTIVITY_NEW_TASK | Intent.FLAG_ACTIVITY_CLEAR_TASK);
startActivity(intent);
finish();
}
@Override
public void onClick(View view) {
if(view == mLogOutButton){
logout();
} else if (view == mFindSpotsButton){
Intent findSpotIntent = new Intent (AccountActivity.this, MapsActivity.class);
startActivity(findSpotIntent);
}
}
}
