android - Android の可視性とレイアウト GONE VISIBLE サイクルがレイアウトに重なる

Question

動画を見て気にならない方は

親を持つレイアウトがあります: 相対レイアウト、子として 3 つの線形レイアウト: タイトル、メニュー、およびコンテンツ。メニューは作成時に GONE になるように操作され、特定のイベントの後に Visible になり、イベントの反対の後に再び GONE になります。問題は、GONE VISIBLE GONE の最初のサイクルの後、GONE をもう一度実行すると UI が台無しになり、コンテンツがメニューと重なってしまうことです。誰が何が起こったのか教えてもらえますか?

これはレイアウトのコードです

</RelativeLayout>

これは可視性を処理するコードです

public void connectService(String ip, String hostType, String name) {
    server = new ConnectedServer(ip, hostType, "Presento");
    Toast.makeText(getApplicationContext(), "You have been connected to Presento Server with IP: " + ip, Toast.LENGTH_LONG).show();

    //RelativeLayout.LayoutParams params = (RelativeLayout.LayoutParams) fragmentContainer.getLayoutParams();
    //RelativeLayout.LayoutParams param2 = (RelativeLayout.LayoutParams) belowMenu.getLayoutParams();
    //param2.height = 65;
    //param2.addRule(RelativeLayout.ABOVE, R.id.fragment_container);
    //param2.addRule(RelativeLayout.BELOW, R.id.titleBar);
    belowMenu.setVisibility(View.VISIBLE);
        belowMenu.startAnimation(new MyScaler(1.0f, 1.0f, 0.0f, 1.0f, 500, belowMenu, false));

    //belowMenu.setLayoutParams(param2);
    //params.addRule(RelativeLayout.BELOW,R.id.menuBar);
    //fragmentContainer.setLayoutParams(params);
    //fragmentContainer.setVisibility(View.GONE);
    //fragmentContainer.setVisibility(View.VISIBLE);

}

そして、これはGONEのときに処理するコードです

connectButton.setOnClickListener(new View.OnClickListener() {

            @Override
            public void onClick(View v) {
                // TODO Auto-generated method stub
                //if not yet connected to a server, find a server through jmdns and get the ip
                if (server == null) {
                    //setting device's ip address
                    myIpAddress = getMyIpAddress();
                    InetAddress inet = intToInetAddress(ipStringToInt(myIpAddress));
                    if (myIpAddress.equals("")) alertMessage("You don't seem to be connected to a Wi-Fi Service, please make sure that you are connected and try to connect again.", "Something went wrong");
                    else {
                        new SeekServer(inet, MenuActivity.this).execute(jmdns);
                    }
                }
                //server already connected
                else {
                    FragmentManager FM = getSupportFragmentManager();
                    FragmentTransaction FT = FM.beginTransaction();
                    String sessionID = pref.getString("sessionID", "0");
                    FT.setCustomAnimations(R.anim.slide_in_right, R.anim.slide_out_left);
                    try {
                    RemoteControlFragment remote = (RemoteControlFragment)FM.findFragmentById(R.id.fragment_container);

                        status.setText(accountName);

                        TutorialFragment tutor = new TutorialFragment();
                        FT.replace(R.id.fragment_container, tutor);
                        FT.addToBackStack(null);
                        FT.commit();
                    }

                        } else {
                            String accountName = pref.getString("accountName", "");
                            status.setText(accountName);

                        catch (ClassCastException ex2) {

                        }

                        try {

                        } catch (IOException e) {

アニメーションクラス

public class MyScaler extends ScaleAnimation {

        private View mView;

        private LayoutParams mLayoutParams;

        private int mMarginBottomFromY, mMarginBottomToY;

        private boolean mVanishAfter = false;

        public MyScaler(float fromX, float toX, float fromY, float toY, int duration, View view,
                boolean vanishAfter) {
            super(fromX, toX, fromY, toY);
            setDuration(duration);
            mView = view;
            mVanishAfter = vanishAfter;
            mLayoutParams = (LayoutParams) view.getLayoutParams();
            int height = mView.getHeight();
            mMarginBottomFromY = (int) (height * fromY) + mLayoutParams.bottomMargin - height;
            mMarginBottomToY = (int) (0 - ((height * toY) + mLayoutParams.bottomMargin)) - height;
        }

        @Override
        protected void applyTransformation(float interpolatedTime, Transformation t) {
            super.applyTransformation(interpolatedTime, t);
            if (interpolatedTime < 1.0f) {
                int newMarginBottom = mMarginBottomFromY
                        + (int) ((mMarginBottomToY - mMarginBottomFromY) * interpolatedTime);
                mLayoutParams.setMargins(mLayoutParams.leftMargin, mLayoutParams.topMargin,
                    mLayoutParams.rightMargin, newMarginBottom);
                mView.getParent().requestLayout();
            } else if (mVanishAfter) {
                mView.setVisibility(View.GONE);
            }
        }

    }

最初はアニメーションが原因ではないかと疑っていましたが、ビデオと同じ結論に達したアニメーションなしで GONE と VISIBLE をはっきりと使用しました。
