我在我的应用程序中使用 facebook 登录并且它工作正常，但问题是当我单击登录按钮时，它会显示片刻的空白屏幕，我想使用我自己的 asynctask 而不是 facebook。

黑屏

这是我的代码。

ublic class SDLoginActivity extends Activity {

private static final String TAG = SDLoginActivity.class.getSimpleName();
private ImageButton imgbtnFacebookLogin;
private TextView tvUserDetails;
private int counter = 0;

private Session.StatusCallback statusCallback = new SessionStatusCallback();

// ---------------------------------------------------------------------
@Override
public void onActivityResult(int requestCode, int resultCode, Intent data) {
    super.onActivityResult(requestCode, resultCode, data);
    Utilities.showToast(SDLoginActivity.this, "Data == " + data);
    Session.getActiveSession().onActivityResult(this, requestCode, resultCode, data);
}

// ---------------------------------------------------------------------
@Override
protected void onCreate(Bundle savedInstanceState) {
    super.onCreate(savedInstanceState);
    Logger.logger("inside " + TAG);
    setContentView(R.layout.login_layout);
    imgbtnFacebookLogin = (ImageButton) findViewById(R.id.btn_fb_login);
    tvUserDetails = (TextView) findViewById(R.id.tv_user_details);
    Settings.addLoggingBehavior(LoggingBehavior.INCLUDE_ACCESS_TOKENS);
    Session session = Session.getActiveSession();
    if (session == null) {
        if (savedInstanceState != null) {
            session = Session.restoreSession(this, null, statusCallback, savedInstanceState);
        }
        if (session == null) {
            session = new Session(this);
        }
        Session.setActiveSession(session);
        if (session.getState().equals(SessionState.CREATED_TOKEN_LOADED)) {
            session.openForRead(new Session.OpenRequest(this).setCallback(statusCallback));
        }
    }

    imgbtnFacebookLogin.setOnClickListener(new OnClickListener() {
        public void onClick(View view) {
            tvUserDetails.setText("");
            onClickLogin();


        }
    });

    // updateView(session);

}

// ---------------------------------------------------------------------

private class SessionStatusCallback implements Session.StatusCallback {

您可以在 AndroidManifest.xml 中将主题设置为不显示 Facbook Login Activity，如下所示

<activity android:name="com.facebook.LoginActivity" 
          android:theme="@android:style/Theme.NoDisplay" />
