Question

我创建了4个按钮，但只有facebook登录按钮才会响应。

public class MainActivity extends AppCompatActivity implements GoogleApiClient.OnConnectionFailedListener, View.OnClickListener {

private Button buttonRegistrujSe, buttonPrijavaRegistrovaniKorisnik;
private LoginButton loginButton;
private CallbackManager callbackManager;
private TextView info;

@Override
protected void onCreate(Bundle savedInstanceState) {

    super.onCreate(savedInstanceState);
    FacebookSdk.sdkInitialize(getApplicationContext());
    setContentView(R.layout.activity_main);
    AppEventsLogger.activateApp(this);


    SignInButton signInButton = (SignInButton) findViewById(R.id.sign_in_button);
    findViewById(R.id.sign_in_button).setOnClickListener(this);

    GoogleSignInOptions gso = new GoogleSignInOptions.Builder(GoogleSignInOptions.DEFAULT_SIGN_IN)
            .requestEmail()
            .build();

    GoogleApiClient mGoogleApiClient;
    mGoogleApiClient = new GoogleApiClient.Builder(this)
            .enableAutoManage(this /* FragmentActivity */, this /* OnConnectionFailedListener */)
            .addApi(Auth.GOOGLE_SIGN_IN_API, gso)
            .build();

    buttonRegistrujSe = (Button) (findViewById(R.id.button_registruj_se));
    buttonRegistrujSe.setOnClickListener(new View.OnClickListener() {
        @Override
        public void onClick(View v) {
            Intent i = new Intent(MainActivity.this, RegistrationActivity.class);
            startActivity(i);
        }
    });

    buttonPrijavaRegistrovaniKorisnik = (Button) (findViewById(R.id.button_prijava_registrovani_korisnik));
    buttonPrijavaRegistrovaniKorisnik.setOnClickListener(new View.OnClickListener() {
        @Override
        public void onClick(View v) {
            Intent i3 = new Intent(MainActivity.this, LoginActivity.class);
            startActivity(i3);
        }
    });

    callbackManager = CallbackManager.Factory.create();
    setContentView(R.layout.activity_main);
    info = (TextView)findViewById(R.id.info);
    loginButton = (LoginButton)findViewById(R.id.connectWithFbButton);

    loginButton.registerCallback(callbackManager, new FacebookCallback<LoginResult>() {
        @Override
        public void onSuccess(LoginResult loginResult) {

            info.setText(
                    "User ID: "
                            + loginResult.getAccessToken().getUserId()
                            + "\n" +
                            "Auth Token: "
                            + loginResult.getAccessToken().getToken()
            );

        }

        @Override
        public void onCancel() {

            info.setText("Login attempt canceled.");

        }

        @Override
        public void onError(FacebookException e) {

            info.setText("Login attempt failed.");

        }
    });

}

@Override
protected void onActivityResult(int requestCode, int resultCode, Intent data) {
    callbackManager.onActivityResult(requestCode, resultCode, data);
}

@Override
protected void onDestroy() {
    super.onDestroy();
    System.exit(0);
}

@Override
public void onConnectionFailed(@NonNull ConnectionResult connectionResult) {

}

@Override
public void onClick(View view) {

}
}

告诉我你是否需要按下所有那些按下时没有响应的按钮的代码？

这是主要活动的xml文件

Answer 1

尝试在Override OnClick中实现方法。你正在课堂上实现时钟，所以你应该在那里实现这些方法。

@Override
public void onClick(View view) {
switch(view){
case buttonPrijavaRegistrovaniKorisnik: 
//Todo your o'clock code
break;

//todo fill all the buttons.

}

}

Answer 2

而不是编写这行代码：

findViewById(R.id.sign_in_button).setOnClickListener(this);

您应该编写以下代码行：

signInButton.setOnClickListener(new View.OnClickListener() {
    @Override
    public void onClick(View v) {
        Intent i = new Intent(MainActivity.this, your_activity_name.class);
        startActivity(i);
    }
});

或者实现你的覆盖onClick（）方法，如下所示：

@Override
public void onClick(View view) {
    switch (view.getId()) {
    case R.id.signInButton:
        Intent i = new Intent(MainActivity.this, your_activity_name.class);
        startActivity(i);
        break;
    }
}

创建按钮不会在点击时进入新活动
