I want to show transparent blurred tabs, so that listactivity screen behind it shows blurred images
And tabs without divider.
I found a solution by removing item selector background from deselect event and the image you want to set in background of tab group just use that image by using set background resource.
In selector make change
<selector xmlns:android="http://schemas.android.com/apk/res/android">
<item android:drawable="#drawable/selected_tab" android:state_selected="true" />
<item android:drawable="#android:color/transparent" />
</selector>
in tab host make following change
<TabHost xmlns:android="http://schemas.android.com/apk/res/android"
android:id="#android:id/tabhost"
android:layout_width="fill_parent"
android:layout_height="fill_parent"
android:background="#000000" >
<RelativeLayout
android:id="#+id/linearLayoutTab"
android:layout_width="fill_parent"
android:layout_height="fill_parent"
android:orientation="vertical" >
<FrameLayout
android:id="#android:id/tabcontent"
android:layout_width="fill_parent"
android:layout_height="fill_parent" />
<TabWidget
android:id="#android:id/tabs"
android:layout_width="fill_parent"
android:layout_height="wrap_content"
android:layout_alignParentBottom="true"
android:layout_marginBottom="-10dp"
android:tabStripEnabled="true"
android:background="#drawable/unselected_tab"/>
</RelativeLayout>
</TabHost>

I am trying to make a transparent background header for close button. The background header is working as expected, however the background layout can see the visible and button is also not clear.
Am trying to build like this below picture

My code is as follows:
Activity Code
final BottomSheetDialog dialog = new BottomSheetDialog(this, R.style.BottomSheetMainStyle);
`dialog.getWindow().setBackgroundDrawable(new ColorDrawable(Color.TRANSPARENT));
`dialog.show();
Layout Code
<RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android"

Tara, from what i understand from your question, (maybe i am wrong) that you want all edit text's in your layout to scroll up and be in focus whenever u receive a click on any of the EditText's?
Lets say you have 10 EditText's in your layout, and user clicks the 1st one, if all the EditText's scroll up, the item on which the user clicked also moves from focus. This would not be good for the user, as they wont be able to edit on the actual field on which they clicked.
As for the problem, i would say to put all your EditText's inside a ScrollView and put a attribute, android:fillViewport="true" on the scroll view. This will not solve the problem, but you will be able to see the full length and items inside the scroll view on the preview pane.
The soft keyword will cover some area of the screen once it pop's up, but you should be make sure that the user can scroll across each view in your layout.
I want to style the action bar and footer using the background image of header and footer respectively. When it comes to the execution by modifying the layout, it seems there are white spaces which is not pleasant for the appearance. All of my images uses png files with transparent background. Are there any methods for modifying the transparency of the header and footer background ? The below os my relative layout structure :
<?xml version="1.0" encoding="utf-8"?>
<RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android"
xmlns:tools="http://schemas.android.com/tools"
android:layout_width="match_parent"
android:layout_height="match_parent"
android:background="#android:color/transparent" >
<!-- Header aligned to top -->
<RelativeLayout
android:id="#+id/header"
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:layout_alignParentTop="true"
android:background="#drawable/heading"
android:gravity="center" >
<TextView
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:layout_margin="5dp"
android:text="Fixed Header"
android:textColor="#000"
android:textSize="20sp" />
</RelativeLayout>
<!-- Footer aligned to bottom -->
<RelativeLayout
android:id="#+id/footer"
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:layout_alignParentBottom="true"
android:background="#drawable/footer"
android:gravity="center" >
<TextView
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:layout_margin="5dp"
android:text="Fixed Footer"
android:textColor="#000"
android:textSize="20sp" />
</RelativeLayout>
<!-- Scrollable Item below header and above footer -->
<ScrollView
android:id="#+id/scrollableContents"
android:layout_width="fill_parent"
android:layout_height="fill_parent"
android:layout_above="#id/footer"
android:layout_below="#id/header"
android:background="#ff5" >
<!-- Inflate the contents of the ScrollView dynamicaly -->
</ScrollView>
</RelativeLayout>
The white part of your header & footer comes from activity background (because listview is below header and above footer) which could be changed by using styles :
Define custom color in res/values/colors.xml
<color name="custom_theme_color">#b0b0ff</color>
Create a style in res/values/styles.xml
<style name="CustomTheme" parent="android:Theme.Light">
<item name="android:windowBackground">#color/custom_theme_color</item>
<item name="android:colorBackground">#color/custom_theme_color</item>
</style>
(windowBackground can be a drawable reference too)
Set this style to your activity in Manifest.xml :
<activity
android:name="myActivity"
android:theme="#style/CustomTheme">

I've got a layout with a textview with some buttons at the bottom. The textview is set to expand to fill the space. This is fine. However, when I change the textview to a webview, the webview does not expand to fill the space. What's wrong?
This is working fine:
<?xml version="1.0" encoding="utf-8"?>
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:layout_width="match_parent"
android:layout_height="match_parent"
android:orientation="vertical" >
<ScrollView
android:layout_width="fill_parent"
android:layout_height="0dp"
android:layout_weight="1"
>
<!-- height set to fill because background is black and we want
the light background -->
<TextView
style="#style/subtopicView"
android:id="#+id/subtopic_content"
android:layout_width="fill_parent"
android:layout_height="fill_parent"
/>
</ScrollView>
<include layout="#layout/include_html_view_footer" />
</LinearLayout>
This is not, but the only change is the textview to a webview and all other values remain the same.
<?xml version="1.0" encoding="utf-8"?>
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:layout_width="match_parent"
android:layout_height="match_parent"
android:orientation="vertical" >
<ScrollView
android:layout_width="fill_parent"
android:layout_height="0dp"
android:layout_weight="1"
>
<!-- height set to fill because background is black and we want
the light background -->
<WebView
style="#style/subtopicView"
android:id="#+id/subtopic_content"
android:layout_width="fill_parent"
android:layout_height="fill_parent" />
</ScrollView>
<include layout="#layout/include_html_view_footer" />
</LinearLayout>
the include is simply this:
<?xml version="1.0" encoding="utf-8"?>
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:layout_width="fill_parent"
android:layout_height="wrap_content"
android:background="#color/tintedColour"
android:orientation="horizontal"
android:paddingBottom="#dimen/spacer"
android:paddingTop="#dimen/spacer" >
<Button
android:id="#+id/PrevPage"

android:layout_width="0dp"
android:layout_height="wrap_content"
android:layout_weight="1"
android:text="#string/previous" />
<Button
android:id="#+id/NextPage"
style="?android:attr/buttonStyleSmall"
android:layout_width="0dp"
android:layout_height="wrap_content"
android:layout_weight="1"
android:text="#string/next" />
<Button
android:id="#+id/Copy"
style="?android:attr/buttonStyleSmall"
android:layout_width="0dp"
android:layout_height="wrap_content"
android:layout_weight="1"
android:text="#string/copyclipboard" />
</LinearLayout>
Thanks for any help.
It's generally a bad idea to nest scrollable elements like you have done by including a WebView inside a ScrollView. Touch events will be unpredictable, and it would probably be a better idea to drop the ScrollView altogether.
That said, the height of your WebView is set to fill_parent. However, the ScrollView is simultaneously trying to minimize the size of its children. As Romain Guy writes in a blog post on this topic:
In attempt to achieve this effect, I have seen several Android developers try to set the height of the view inside the scroll view to fill_parent. Doing so does not work and leads to the following result:
To understand this result, you must remember that android:layout_height=”fill_parent” means “set the height to the height of the parent.” This is obviously not what you want when using a ScrollView. After all, the ScrollView would become useless if its content was always as tall as itself.
By setting android:fillViewport="true", the scroll view’s child expands to the height of the ScrollView. (When the child is taller than the ScrollView, the attribute has no effect.)
So android goes out of its way to build this nice UI guide for everyone to use. But I don't see anywhere where it shows code examples of how to build these elements.
The UI guidelines for tabs can be found here. http://developer.android.com/design/building-blocks/tabs.html.
Does anyone know how to create tabs likes the this one?
Any help would be appreciated, thanks.
SOLUTION POSTED
Ok, so here is what I ended up doing after probably wasting about 10 hours trying to make some good looking tabs.
First I scrapped the whole idea of using android's implementation of tabs. For one reason the tab host widget is suppose to deprecated for the action bar, but the action bar only works from android 3 on.
I finally figured out that if a used a linear layout and as the background for the linear layout i put the image I wanted to use (using a 9 patch image). Then create another linearlayout and textview in order to put text over top of that linearlayout. Then make your linear layout clickable. Then as you get more advanced you can make you linear layout background a xml selector and you are good to go. Incase you didn't get all that here is my code.
LinearLayout
<LinearLayout
xmlns:android="http://schemas.android.com/apk/res/android"
android:layout_width="fill_parent"
android:layout_height="50dp"
android:background="#color/main_screen_bg_color"
android:orientation="horizontal"
android:padding="2dp" >
<LinearLayout
android:layout_width="fill_parent"
android:layout_height="fill_parent"
android:layout_weight="1"
android:background="#drawable/selector_not_current"
android:clickable="true"
android:onClick="onClickSub"
android:orientation="horizontal" >
<LinearLayout
android:layout_width="fill_parent"
android:layout_height="fill_parent"
android:layout_weight="1"
android:gravity="center"
android:orientation="vertical" >
<TextView
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:singleLine="true"
android:text="Example 1"
android:textColor="#color/black"
android:textSize="18sp"
android:textStyle="bold" />
</LinearLayout>
</LinearLayout>
<LinearLayout
android:layout_width="fill_parent"
android:layout_height="fill_parent"
android:layout_weight="1"
android:background="#drawable/selector_current"
android:clickable="true"
android:onClick="onClickFoodDetails"
android:orientation="horizontal" >
<LinearLayout
android:layout_width="fill_parent"
android:layout_height="fill_parent"
android:layout_weight="1"
android:gravity="center"
android:orientation="vertical" >
<TextView
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:singleLine="true"
android:text="Example 2"
android:textColor="#color/black"
android:textSize="18sp"
android:textStyle="bold" />
</LinearLayout>
</LinearLayout>
</LinearLayout>
Example Selector
<selector xmlns:android="http://schemas.android.com/apk/res/android">
<item android:state_pressed="true"
android:drawable="#drawable/selected_pressed_tab" /> <!-- pressed -->
<item android:state_focused="true"
android:drawable="#drawable/selected_pressed_tab" /> <!-- focused -->
<item android:drawable="#drawable/selected_tab" /> <!-- default -->
Hope this helps everyone. Android tabs were just too difficult an annoying to work with that it was easier just to make my own from scratch. Good Luck!
do something like this.
this is a full working code. enjoy
somewhere in oncreate method of activity extending Tabactivity
tabHost = getTabHost();
Intent intent;
intent = new Intent().setClass(this, FirstActvity.class);
setupTab("NearBy", intent, R.drawable.firsttabdrawable);
intent = new Intent().setClass(this, SecondActivity.class);
setupTab("History", intent, R.drawable.secondtabdrawable);
intent = new Intent().setClass(this, ThirdActivity.class);
setupTab("Setting", intent, R.drawable.thirdtabdrawable);
define setupTab methods as
private void setupTab(String tag, Intent intent, int selectorId) {
View tabView = LayoutInflater.from(tabHost.getContext()).inflate(R.layout.view, null);
tabView.setBackgroundResource(selectorId);
TabSpec setContent = tabHost.newTabSpec(tag).setIndicator(tabView).setContent(intent);
tabHost.addTab(setContent);
}
view.xml as
<?xml version="1.0" encoding="utf-8"?>
<LinearLayout
xmlns:android="http://schemas.android.com/apk/res/android"
android:layout_width="fill_parent"
android:layout_height="fill_parent"
>
</LinearLayout>
and firsttabdrawable.xml in drawable folder as
<?xml version="1.0" encoding="utf-8"?>
<selector xmlns:android="http://schemas.android.com/apk/res/android">
<!-- When selected, use grey -->
<item android:drawable="#drawable/selectedfirsttabimage"
android:state_selected="true" />
<!-- When not selected, use white-->
<item android:drawable="#drawable/notselectedfirsttabimage" />
</selector>
define secondtabdrawable.xml and thirddrawable.xml in the same way
The tabs you need are part of the ActionBar. Specifically they are displayed when the ActionBar is in Navigation Tab mode.
http://developer.android.com/guide/topics/ui/actionbar.html
(see under "Adding Navigation Tabs")
You may want to use www.ActionbarSherlock.com which is a library that will give you the ActionBar on nearly all versions of Android. It works the same as the official one, and includes the tabs.
Do not use the TabActivity any more, it's old and being deprecated. ActionBar is the future.
