I'm working on an android app and am using a toolbar at the top of the screen and a navigation bar at the bottom of the screen. I'm using a single activity to create the top and bottom toolbars and fragments to change the content between the toolbars. However, when the contents in the fragment go beyond the size of the screen, the bottom bar disappears.
Here is my home activity xml:
<?xml version="1.0" encoding="utf-8"?>
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
xmlns:tools="http://schemas.android.com/tools"
android:id="#+id/activity_home"
android:orientation="vertical"
android:layout_width="match_parent"
android:layout_height="match_parent"
tools:context="com.rentables.testcenter.HomeActivity">
<include
android:id="#+id/toolbar_main"
layout="#layout/toolbar_main"
android:layout_width="match_parent"
android:layout_height="wrap_content" />
<fragment android:name="com.rentables.testcenter.HomeFragment"
android:id="#+id/fragment_place"
android:layout_weight="0"
android:layout_width="match_parent"
android:layout_height="wrap_content"
tools:layout="#layout/fragment_home" />
<LinearLayout
android:layout_width="match_parent"
android:layout_height="0dp"
android:layout_weight="1"
android:gravity="bottom">
<include
android:id="#+id/toolbar_navigate"
layout="#layout/toolbar_navigate"
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:layout_gravity="center|bottom"/>
</LinearLayout>
</LinearLayout>
Im guessing it's because of the inner linear layout I have, but I wasn't sure how else to get the nav bar to stay static at the bottom. Any help would be awesome. Thanks
Figured it out. I just changed the whole thing to a relative layout, got rid of the inner linear layout, and instead of gravity I used alignParentBottom="true".

I am creating a calculator app in android.Just like a modern calculator you see in your android device. I have created a TextViewand below that, all my buttons are present.I also want to include the trignometric functions so when buttons layout is swipped, i want to show trignometric function and when it is swiped back it show numeric buttons.The TextView should remain constant at the top.Can you somebody please guide me how to do that?
Yes u can do it.
here is an example how to do it
Layout Example
<?xml version="1.0" encoding="utf-8"?>
<RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android"
xmlns:app="http://schemas.android.com/apk/res-auto"
android:layout_width="match_parent"
android:layout_height="match_parent" >
<!-- Static content -->
<LinearLayout
android:id="#+id/ll_bottom"
android:layout_width="match_parent"
android:layout_height="100dp"
android:layout_alignParentBottom="true"
android:background="#color/holo_blue_light"
android:orientation="vertical" />
<!-- ViewPager Indicator -->
<com.viewpagerindicator.LinePageIndicator
android:id="#+id/view_pager_indicator"
android:layout_width="fill_parent"
android:layout_height="20dp"
android:layout_above="#id/ll_bottom"
android:background="#color/holo_orange_light"
app:lineWidth="10dp"
app:selectedColor="#fff"
app:strokeWidth="10dp"
app:unselectedColor="#888888" />
<!-- ViewPager containing fragments with different views -->
<android.support.v4.view.ViewPager
android:id="#+id/view_pager"
android:layout_width="match_parent"
android:layout_height="match_parent"
android:layout_above="#id/view_pager_indicator"
android:layout_alignParentTop="true"
android:background="#color/holo_red_light" />
</RelativeLayout>
In the blue region you place your static content which doesn't change like the
The orange region is used by the
ViewPagerIndicator and finally the red region is the one of the ViewPager. this area is swipeable.
I'm looking for a custom TabLayout. The icon of the Tab in the middle needs a margin to overlay the content. Please check out the image below.
What I've tried so far
Tab.setCustomView() with a margin. That doesn't overlay the content though.
Looked for TabLayout libraries that give such flexibility. Didn't find anything that fits my need.
Re-invent the wheel?
Since I don't need any complicated scrolling functionality, I could develop my own TabLayout with a couple ViewGroups,TextView and ImageView. Before I have to do that:
Do you know of any library that would do that?
How would you approach it?
Any help would be greatly appreciated!
I achieved that by the combination of a custom library and the floating action button.
The library: MagicIndicator on GitHub
I set the icon of the middle fragment to an empty icon and positioned the floating action button in the middle to overlay the TabLayout. It looks like this:

I have a problem with my layout. I use ViewPager tab layout in my app and I would like to use transparent action bar. I managed to prevent the elements from hiding behind action bar, but the problem is that elements sill hide behind the tabs bar. How to fix it?
xml file
<?xml version="1.0" encoding="utf-8"?>
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:paddingTop="?android:attr/actionBarSize"
android:layout_width="match_parent"
android:layout_height="match_parent"

Use CoordinatorLayout to wrap all components and use this app:layout_behavior="#string/appbar_scrolling_view_behavior" in your RelativeLayout where xmlns:app="http://schemas.android.com/apk/res-auto"
I am currently working on an android project and I am trying to make use of fragments. I've got it mostly working, however, I can't get the layout right.
In the layout there should be a slide in navigation drawer from the left and a slide in navigation drawer from the right.
At the top of the activity there should be a fragment and underneath that another fragment. The top fragment being smaller than the below fragment.
Even though I have set the height for the fragment it is taking up the whole screen and both fragments are overlapping below. Below is an image which should hopefully highlight what I am trying to achieve.
Below is the XML for the FragmentActivity
<?xml version="1.0" encoding="utf-8"?>
<RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:layout_width="fill_parent"
android:layout_height="fill_parent">
<android.support.v4.widget.DrawerLayout
xmlns:android="http://schemas.android.com/apk/res/android"
android:id="#+id/drawer_layout"
android:layout_width="match_parent"
android:layout_height="match_parent">
<fragment android:name="com.BoardiesITSolutions.MysqlManager.QueryEditor"
android:id="#+id/fragment_query_editor"
android:layout_width="match_parent"
android:layout_height="10dp"/>
<fragment android:name="com.BoardiesITSolutions.MysqlManager.MainContentFragment"
android:layout_width="fill_parent"
android:layout_height="100dp" />
<ListView xmlns:android="http://schemas.android.com/apk/res/android"
android:id="#+id/left_drawer"
android:layout_width="280dp"

android:choiceMode="singleChoice"
android:divider="#4e4e4e"
android:dividerHeight="1dp"
android:background="#111" />
</android.support.v4.widget.DrawerLayout>
</RelativeLayout>
I've taken out the slide in nav menu from the right for the time being just while I get the basic layout correct
Below is the XML for the query editor fragment
<?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="100dp"

<TextView

android:text="QUERY EDITOR"/>
</LinearLayout>
Thanks for any help you can provide
Your drawer layout should be the outermost parent. You should then have a layout with matchparent height and width that you can use to contain your inner UI fragments. The 2nd and 3rd layouts should be your slide in drawers with the relevant left and right layout_gravity set.
In summary, an outer drawer that contains 3 inner layouts.
Sorry I am on a tablet so can't show this for you but it is all explained here.

When I put ScrollView into the content of a DrawerLayout, I am nolonger able to open the drawer by swiping from the side.
Activity layout:
<android.support.v4.widget.DrawerLayout
xmlns:android="http://schemas.android.com/apk/res/android"
xmlns:tools="http://schemas.android.com/tools"
android:id="#+id/drawer_layout"
android:layout_width="match_parent"
android:layout_height="match_parent">
<!-- The menu_main content view -->
<FrameLayout
android:id="#android:id/content"
android:layout_width="match_parent"
android:layout_height="match_parent"/>
<!-- The navigation drawer -->
<ListView
android:name="com.gumtree.androidapp.DrawerFragment"
android:id="#+id/drawer"
android:layout_width="240dp"
android:layout_height="match_parent"
android:layout_gravity="start" />
</android.support.v4.widget.DrawerLayout>
In Activity's onCreate I add a fragment which has following layout:
<ScrollView
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">
<LinearLayout
android:orientation="vertical"
android:layout_width="match_parent"
android:layout_height="match_parent">
<ImageView
android:layout_height="160dp"
android:layout_width="match_parent"/>
<TextView
android:id="#+id/headline"
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:textSize="#dimen/headline_text_size"
android:padding="#dimen/detail_text_padding"
android:textIsSelectable="false"/>
<TextView
android:id="#+id/description"
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:textSize="#dimen/description_text_size"
android:padding="#dimen/detail_text_padding"
android:textIsSelectable="false"/>
</LinearLayout>
</ScrollView>
Without the ScrollView everything works fine and I am able to open the drawer by swiping from the side. However when I add the ScrollView, it stops working.
The problem here was silly named ID of FrameLayout used as content container of DrawerLayout. I used system ID (android.R.id.content) which caused that the content fragment was put on the top of all other views - even the drawer.
It also caused fragment's layout to overlap the drawer and - related to this question - blocked the drawer from receiving touch events. The touch events were taken by fragment's ScrollView.
Conclusion: DO NOT USE SYSTEM IDs (android.R.*) WHERE IT IS NOT NEEDED.
I just wanted it to look nice and clean.. Silly me :)
