It is very simple. Just place those 3 buttons in a layout and set the visibility of that layout to gone/visible on click of hide/unhide button.

EDIT :

It will be like put your spinners which you like to hide/unhide in a layout and provide an ID for it.

<ImageButton
        android:id="@+id/setting"
        android:layout_width="wrap_content"
        android:layout_height="45dip"
        android:layout_alignParentRight="true"
        android:layout_below="@+id/Editsearch"
        android:src="@drawable/button_setting" />

    <RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android"
    android:layout_width="fill_parent"
    android:layout_height="fill_parent" 
    **android:id="@+id/submenu_layout"**
    android:layout_below="@+id/Editsearch"
    >
    <Spinner
        android:id="@+id/category1"
        android:layout_width="135dp"
        android:layout_height="45dp"
        android:layout_alignParentLeft="true"
        android:background="@android:drawable/btn_default"
        android:text="Category" />
    <Spinner
        android:id="@+id/category2"
        android:layout_width="135dp"
        android:layout_height="45dp"
        android:layout_alignParentLeft="true"
        android:layout_below="@id/category1"
        android:background="@android:drawable/btn_default"
        android:text="Category" />
    <Spinner
        android:id="@+id/category3"
        android:layout_width="135dp"
        android:layout_height="45dp"
        android:layout_alignParentLeft="true"
        android:layout_below="@+id/category2"
        android:background="@android:drawable/btn_default"
        android:text="Category" />
    </RelativeLayout>

Then use this id to take the reference of this layout in your code.

RelativeLayout submenuLayout = (RelativeLayout) findViewById(R.id.submenu_layout);

EDIT 2:

After that OnClick of setting imageButton :

 if(submenuLayout .getVisibility() == View.VISIBLE)
    submenuLayout .setVisibility(View.GONE);
    else
        submenuLayout .setVisibility(View.VISIBLE);

回答2:

use this code

to make it visible on button click

themeUrlRow.setVisibility(View.VISIBLE);

to make it invisible

themeUrlRow.setVisibility(View.GONE);

and in xml put the button in a layout and also make it invisible and in on clicklistener add the above code.

xml code

            <LinearLayout
               android:id="@+id/themeUrlRow"
            android:layout_width="fill_parent"
            android:gravity="center"
            android:visibility="gone" > />

            <Button
                android:id="@+id/register"
                android:layout_width="wrap_content"
                android:layout_height="wrap_content"
                android:gravity="center"
                android:text="Register" />

            <Button
                android:id="@+id/register"
                android:layout_width="wrap_content"
                android:layout_height="wrap_content"
                android:gravity="center"
                android:text="Register" />
        </LinearLayout>
