    android:id="@+id/viewimage_slide_title">

<Button

titlebar = (RelativeLayout) findViewById(R.id.viewimage_slide_title);
requestWindowFeature(Window.FEATURE_CUSTOM_TITLE);

setContentView(R.layout.viewimage_slide);

I find the reason , because both the theme (title) and layout I set the backgroud, it is wrong,where I change my theme, so it work. thanks guys for these help me ~~ this is my first question in stackoverflow.

Add one ParentLayout in your XML:

<RelativeLayout
    android:orientation="horizontal"
    android:layout_heigth="fill_parent"
    android:layout_width="fill_parent">
<RelativeLayout
    android:background="@drawable/iphone_header_bg"
    android:orientation="horizontal"
    android:id="@+id/viewimage_slide_title">

<Button
    android:id="@+id/third_image_button_back"
    android:layout_width="wrap_content"
    android:layout_height="wrap_content" />
<TextView
    android:id="@+id/third_title_text"
    android:layout_width="wrap_content"
    android:layout_height="wrap_content"/>
</RelativeLayout>
</RelativeLayout>

If you want to remove your backgroundImage then use,

titlebar.setBackgroundDrawable(null);
titlebar.setVisibility(View.GONE);

First Of all , what do you mean by custom title bar? Second thing is what i have understood by your code is you want to hide a layout ( viewimage_slide_title.xml) .

For this you simple provide a id to the Relative layout and set visibility gone to the layout rather than the button or textview .

You are able to hide button and text view but failed to hide tilte's background image because background set to relative layout not to button or text.

here is code -

<RelativeLayout
android:background="@drawable/iphone_header_bg"
android:orientation="horizontal"
android:id="@+id/viewimage_slide_title">

<Button
android:id="@+id/third_image_button_back"
android:layout_width="wrap_content"
android:layout_height="wrap_content" />

<TextView
android:id="@+id/third_title_text"
android:layout_width="wrap_content"
android:layout_height="wrap_content"/>

</RelativeLayout>

Then your main Activity : -

titlebar = (RelativeLayout) findViewById(R.id.viewimage_slide_title);

MianActivity.titlebar.setVisibility(View.GONE);
