Android 谷歌游戏服务

我对Google Play游戏服务有一个问题，在启动和恢复游戏时，从切换应用程序到选择主页，排行榜会随机启动。我怎样才能改变这种行为

if (isSignedIn()) {
        startActivityForResult(getGamesClient().getAllLeaderboardsIntent(),
                RC_UNUSED);
public int gameMode;

public static void showLeaderboard(int mode) {
    me.gameMode = mode;
    me.runOnUiThread(new Runnable() {
        public void run() {
            if (me.isSignedIn())
                me.onShowLeaderboard();
            else
                me.SignIn();
        }
    });
}

public static void submitScore(final int score) {
    me.gameMode = score / 1000000;
    me.runOnUiThread(new Runnable() {
        public void run() {
            me.onSubmitScore(score % 1000000);
        }
    });

}


   public void onShowLeaderboard() {
    if (isSignedIn()) {
        startActivityForResult(getGamesClient().getAllLeaderboardsIntent(),
                RC_UNUSED);
    } else {
        showAlert(getString(R.string.signing_in));
        this.SignIn();
    }
}

public void onSubmitScore(int score) {
    if (isSignedIn()) {
        switch (gameMode) {
        case 1:
            getGamesClient().submitScore(getString(R.string.leaderboard1),
                    score);
            break;
        case 2:
            getGamesClient().submitScore(getString(R.string.leaderboard2),
                    score);
            break;
        case 3:
            getGamesClient().submitScore(getString(R.string.leaderboard3),
                    score);
            break;
        }
    } else {
        showAlert(getString(R.string.signing_in));
        this.SignIn();
    }
}

boolean verifyPlaceholderIdsReplaced() {
    final boolean CHECK_PKGNAME = true; // set to false to disable check
                                        // (not recommended!)

    // Did the developer forget to change the package name?
    if (CHECK_PKGNAME && getPackageName().startsWith("com.google.example.")) {
        Log.e(TAG,
                "*** Sample setup problem: "
                        + "package name cannot be com.google.example.*. Use your own "
                        + "package name.");
        return false;
    }

    return true;
}

public void SignIn() {
    if (!verifyPlaceholderIdsReplaced()) {
        showAlert("Sample not set up correctly. See README.");
        return;
    }

    // start the sign-in flow
    beginUserInitiatedSignIn();
}

@Override
public void onSignInFailed() {
    System.out.println("SignIn Failed!");
}

@Override
public void onSignInSucceeded() {
    System.out.println("SignIn Successed!");
    onShowLeaderboard();
}

我认为这是因为在您的方法“OnSignensAccepted”中，您调用了“OnSowleadboard（）；”因此，每次启动（第一次或恢复）应用程序时，它都将登录，如果登录过程成功，则它将启动方法“onshowleadboard（）；”

对于特定的引导板，您应该使用：

startActivityForResult(Games.Leaderboards.getLeaderboardIntent(getApiClient(),
                YOUR_LEADERBOARD_ID), REQUEST_LEADERBOARD);

而不是使用：

startActivityForResult(getGamesClient().getAllLeaderboardsIntent(),
            RC_UNUSED);

有人能帮忙吗？
