小编Raj*_*aju的帖子

我正在使用谷歌的SlidingTabLayout.由于我只有3个标签要显示,我看到最后一个标签后的空格.请截图如下.

有人可以解释我如何使标签适合整个屏幕.谢谢你的时间.

Swift中Array的removeLast()和popLast()方法有什么区别？他们正在做同样的事情,删除并返回数组的最后一个元素.谁能告诉我什么时候使用什么？

我正试图用Volley打一场休息服务.

public class AuthFunctions {
    private static final String LOGIN_URL = "http://10.0.2.2:8080/stewayservices/user-management/users/10";
    boolean result;
    public boolean loginUser(String email,String password){

        JsonObjectRequest request = new JsonObjectRequest(Request.Method.GET,LOGIN_URL,null,new Response.Listener<JSONObject>() {
            @Override
            public void onResponse(JSONObject response) {
                Log.d("JsonObject Response",response.toString());
                try {
                    JSONObject user = response.getJSONObject("user");
                    String firstName = user.getString("firstName");
                    if (firstName.equals("Lokesh")){
                        result = true;
                    }
                    else{
                        result = false;
                    }
                } catch (JSONException e) {
                    Log.d("Web Service Error",e.getMessage());
                    e.printStackTrace();
                }
            }
        },new Response.ErrorListener() {
            @Override
            public void onErrorResponse(VolleyError volleyError) {
                Log.d("JsonObject Error Response",volleyError.toString());
            }
        }); …

我正在使用firebase文档来使用Facebook登录我的android应用程序.我已成功使用Google和Twitter登录用户.但是当我点击登录Facebook时,该按钮将变为退出按钮.实际上它应该重定向到登录成功活动,因为我配置了FirebaseAuth.AuthStateListener.

我在Activity这里张贴,如果我做错了,请告诉我.

public class MainActivity extends AppCompatActivity implements GoogleApiClient.OnConnectionFailedListener {

    private static final String TAG = "MainActivity";
    private static final int GOOGLE_RC_SIGN_IN = 9001;
    private static final int TWITTER_RC_SIGN_IN = 140;

    private FirebaseAuth mAuth;
    private FirebaseAuth.AuthStateListener mAuthStateListener;

    private GoogleApiClient mGoogleApiClient;
    CallbackManager callbackManager;
    @BindView(R.id.google_signin_button) SignInButton mGoogleSigninButton;
    @BindView(R.id.facebook_login_button) LoginButton mFacebookLoginButton;
    @BindView(R.id.twitter_login_button) TwitterLoginButton mTwitterLoginButton;

    @Override
    protected void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        TwitterAuthConfig authConfig = new TwitterAuthConfig(getString(R.string.twitter_consumer_key), getString(R.string.twitter_consumer_secret));
        Fabric.with(this, new Twitter(authConfig));
        FacebookSdk.sdkInitialize(this);
        setContentView(R.layout.activity_main);

        ButterKnife.bind(MainActivity.this);

        GoogleSignInOptions gso = new GoogleSignInOptions.Builder(GoogleSignInOptions.DEFAULT_SIGN_IN)
                .requestIdToken(getString(R.string.default_web_client_id)) …
