我希望获得有关SetupDriver活动的登录用户的详细信息，并将其存储在firebase数据库中，任何人都可以告诉我该怎么做。我在SetupDriver活动中的当前代码是：
@Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_setup_driver);
mAuth = FirebaseAuth.getInstance();
mDatabase = FirebaseDatabase.getInstance().getReference();
onClickNextDriver();
onClickSignOut();
mAuthListener = new FirebaseAuth.AuthStateListener() {
@Override
public void onAuthStateChanged(@NonNull FirebaseAuth firebaseAuth) {
if(firebaseAuth.getCurrentUser() == null) {
Intent intent = new Intent(SetupDriver.this,Welcome.class);
startActivity(intent);
}
}
};
}
public void onClickNextDriver()
{
test_et = (EditText) findViewById(R.id.test);
driver_btn = (Button)findViewById(R.id.setup_driver_btn);
driver_btn.setOnClickListener(
new View.OnClickListener()
{
@Override
public void onClick(View v) {
getDetails();
setDetails();
if(validate() && validateReg() && validateLicense())
{
//test_et.setText(license_no);
mAuthListener = new FirebaseAuth.AuthStateListener() {
@Override
public void onAuthStateChanged(@NonNull FirebaseAuth firebaseAuth) {
FirebaseUser user = firebaseAuth.getCurrentUser();
if(user != null) {
String name = user.getDisplayName();
String email = user.getEmail();
String uid = user.getUid();
mDatabase.child("name").setValue(name);
}
}
};
Toast.makeText(SetupDriver.this, "success", Toast.LENGTH_SHORT).show();
}
else {
Toast.makeText(SetupDriver.this, "please fill all the details", Toast.LENGTH_SHORT).show();
}
}
}
);
}

您对“ mGoogleClient从未使用”的评论指出了我的解决方案。改变这个：
GoogleApiClient mGoogleApiClient = new GoogleApiClient.Builder(getApplicationContext())...
到这个
mGoogleApiClient = new GoogleApiClient.Builder(getApplicationContext())...
您正在创建GoogleApiClient的第二个实例，而不是定义signin()中使用的类成员。
