TextView in RelativeLayout improper alignment

I need to implement the following UI:
For this, I am using the following layout:
<RelativeLayout
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:background="#android:color/white">
<ImageView
android:id="#+id/news_image0"
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:minHeight="#dimen/news_cell0_imageview_min_height"
android:adjustViewBounds="true"
android:scaleType="fitXY" />
<RelativeLayout
android:id="#+id/news0_cell_image_overlay_layout"
android:layout_width="match_parent"
android:layout_height="match_parent"
android:layout_alignBottom="#+id/news_image0"
android:layout_alignTop="#+id/news_image0"
android:layout_alignLeft="#+id/news_image0"
android:layout_alignStart="#+id/news_image0"
android:layout_alignEnd="#+id/news_image0"
android:layout_alignRight="#+id/news_image0"
android:background="#drawable/news_cell0_overlay_gradient">
<TextView
android:id="#+id/news_title0"
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:layout_centerHorizontal="true"
android:gravity="center_vertical|start"
android:layout_alignParentBottom="true"
android:maxLines="3"
android:ellipsize="end"
android:textColor="#color/colorNewsCellType0TitleText"
android:layout_margin="#dimen/news_cell0_textview_margin"
android:textSize="#dimen/news_cell0_title_text_size"
android:typeface="monospace" />
</RelativeLayout>
</RelativeLayout>
Into the ImageView I am loading image using Picasso from a URL. I am getting output correctly in most of the devices, but in some of the devices running android less than Lollipop, this shows up like the screenshot below. The text shows up at the top, instead of bottom. But I have set android:layout_alignParentBottom="true" for the TextView. The RelativeLayout is rendered correctly, and it fits the image(it has a background gradient, which can clearly be seen at the bottom of the image).
What is causing this problem and how can I solve this?

You can try with FRAMELAYOUT
FrameLayout is designed to block out an area on the screen to display
a single item. Generally, FrameLayout should be used to hold a single
child view, because it can be difficult to organize child views in a
way that's scalable to different screen sizes without the children
overlapping each other.
<FrameLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:layout_width="fill_parent"
android:layout_height="fill_parent">
<ImageView
android:src="#drawable/ic_launcher"
android:scaleType="fitCenter"
android:layout_height="fill_parent"
android:layout_width="fill_parent"/>
<TextView
android:text="Hi.."
android:textSize="17sp"
android:textStyle="bold"
android:layout_height="fill_parent"
android:layout_width="fill_parent"
android:gravity="center|bottom"/>
</FrameLayout>

You can try this layout,
<?xml version="1.0" encoding="utf-8"?>
<RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:background="#android:color/white">
<ImageView
android:id="#+id/news_image0"
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:adjustViewBounds="true"
android:minHeight="100dp"
android:scaleType="fitXY"/>
<TextView
android:id="#+id/news_title0"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:layout_alignBottom="#+id/news_image0"
android:layout_centerHorizontal="true"
android:ellipsize="end"
android:maxLines="3"
android:padding="12dp"
android:text="fsdsdfdsdsfsdfsdf"
android:textColor="#f00"
android:typeface="monospace"/>
</RelativeLayout>

Android ListView with CardView: Last Card not fully displayed when scrolling

I have created a ListView to which I've added CardView.
As you can see in the image, when I start scrolling, the last Card in the ListView is not completely displayed. It scrolls up but it does not come above Android's navigation bar at the bottom. I've been testing on a HTC One M8.
Here is the ListView:
<?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="fill_parent"
android:orientation="vertical">
<ListView
android:id="#+id/wanna_list"
android:layout_width="match_parent"
android:layout_height="fill_parent"
android:divider="#null"/>
</LinearLayout>
And here is the CardView that I inflate and set into the adapter of the listview:
<?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="wrap_content" >
<android.support.v7.widget.CardView
xmlns:android="http://schemas.android.com/apk/res/android"
xmlns:card_view="http://schemas.android.com/apk/res-auto"
android:layout_width="match_parent"
android:layout_height="200dp"
android:id="#+id/cv"
android:foreground="?android:attr/selectableItemBackground"
android:clickable="true"
card_view:cardCornerRadius="6dp"
card_view:cardUseCompatPadding="true"
card_view:cardElevation="2dp">
<!-- compat padding is required if using AppCompat -->
<RelativeLayout
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:padding="16dp" >
<ImageView
android:layout_width="100dp"
android:layout_height="100dp"
android:id="#+id/thumbnail"
android:layout_alignParentLeft="true"
android:layout_alignParentTop="true"
android:layout_marginRight="16dp"
android:src="#drawable/india"
android:scaleType="centerCrop" />
<TextView
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:id="#+id/firstLine"
android:layout_toRightOf="#+id/thumbnail"
android:layout_alignParentTop="false"
android:textSize="20sp"
android:text="Tennis with Peter"
android:layout_alignTop="#+id/thumbnail" />
<TextView
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:id="#+id/secondLine"
android:layout_below="#+id/firstLine"
android:text="10 Oct at 7pm"
android:layout_alignLeft="#+id/firstLine" />
<Button
android:layout_width="180dp"
android:layout_height="wrap_content"
android:text="YES"
android:id="#+id/button3"
android:layout_alignParentBottom="true"
android:layout_alignParentLeft="true"
android:layout_alignLeft="#+id/thumbnail" />
<Button
android:layout_width="60dp"
android:layout_height="wrap_content"
android:text="NO"
android:id="#+id/button4"
android:layout_toRightOf="#+id/button3"
android:layout_alignBottom="#+id/button3"
android:layout_alignParentRight="true"
android:layout_alignParentEnd="false" />
</RelativeLayout>
</android.support.v7.widget.CardView>
</LinearLayout>
I have also tried my card view layout without wrapping it in a LinearLayout and it still does not work.
Is there a setting in the layout xml that will take care of this?
Thanks in advance.

android:layout_marginBotton=" "
add margin bottom should try once.

So adding a margin to the bottom of listView worked, as below:
<ListView
android:id="#+id/wanna_list"
android:layout_width="match_parent"
android:layout_height="match_parent"
android:divider="#null"
android:layout_marginBottom="80dp" />
Am surprised this is the only way to get it to work though. I would have assumed the Android framework took care of these things.

Is the ListView in a Fragment ? As far as I know, this is possible when you have used a Toolbar such as :
<android.support.v7.widget.Toolbar
...
app:layout_scrollFlags="scroll"
...
>
</android.support.v7.widget.Toolbar>
then change the attribute to:
app:layout_scrollFlags="enterAlwaysCollapsed"
Adding margin at the bottom of ListView is sort of a hack. I have given a probable cause for this. If this is the case, then you won't need to add the margin in ListView. There is always a reason behind the UI behavior. I hope this helps.

Android relative layout bottom margin not working correctly

I'm creating a dynamic layout application for the first time. I'm fetching the data from an online database and using an XML layout to present it to the user.
I'm having an issue with the bottom margin. It's being covered up by another layout that it inside the main relative layout and I have tried everything to make it show and got no results.
So after nearly two hours of playing with the setting I have decided to ask you guys, to point me out on what I am doing wrong.
This is how it looks on the screen
You can notice the bottom gray border part is missing. I'm using a relative layout inside of a relative layout. So the main layout is gray and serves as background for the border, while the second relative layout actually contains all other views.
This is my XML file
<?xml version="1.0" encoding="utf-8"?>
<RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:layout_width="match_parent" android:layout_height="wrap_content"

android:layout_gravity="center_vertical"
android:layout_marginLeft="8dp"
android:layout_marginRight="30dp"
android:textAppearance="#android:style/TextAppearance.Small"
android:gravity="fill" />
<ImageView
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:id="#+id/item_icon"
android:layout_gravity="center_vertical|right"
android:background="#android:color/transparent"

</RelativeLayout>
</RelativeLayout>
I have added an image of the structure so it's easier to understand what I am doing here.
I apologize of this questions sounds noobish or something, this is my third app for Android and I'm still learning, I'm trying to learn on how to create dynamic views/layouts with this one. I appreciate the time you guys are taking to read and assist me with this.
Thanks in advance.

Here's how your 2nd RelativeLayout and 1st FrameLayout should look. You aren't making use of the padding attribute.
<RelativeLayout
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:layout_marginBottom="5dp"
android:padding="2dp"
android:background="#e8e8e8"
android:id="#+id/item_body">
<FrameLayout
android:layout_width="fill_parent"
android:layout_height="fill_parent"
android:background="#android:color/white"
android:id="#+id/item_button"
android:clickable="true"
android:longClickable="true"
android:focusable="true"
android:focusableInTouchMode="false"
android:minHeight="55dp">

(Android - xml) Gridview and ImageView scale type centerCrop

I'm trying to show a list of images in a GridView, and I want to crop only the center of the images in this list. So below is the layout of each image item:
<?xml version="1.0" encoding="utf-8"?>
<ImageView xmlns:android="http://schemas.android.com/apk/res/android"
android:id="#+id/place_image"
android:src="#drawable/ic_res"
android:layout_width="100dp"
android:layout_height="100dp"
android:scaleType="centerCrop"/>
And here is the layout that contains the grid view:
<?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" >
<LinearLayout android:id="#+id/upload_view"
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:orientation="vertical"
android:background="#f6f6f6"
android:padding="10dp"
android:visibility="gone">
<LinearLayout android:layout_width="match_parent"
android:layout_height="wrap_content"
android:orientation="horizontal">
<ImageButton android:id="#+id/photo_select"
android:layout_width="50dp"
android:layout_height="40dp"
android:scaleType="fitXY"
android:src="#drawable/ic_photo"/>
<EditText android:id="#+id/photo_caption"
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:hint="#string/caption"
android:inputType="textMultiLine"/>
</LinearLayout>
<TextView android:id="#+id/photo_path"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:text="" />
<Button android:id="#+id/photo_upload"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:text="#string/upload_photo"
android:textStyle="bold"
android:textColor="#ffffff"
android:layout_gravity="right"/>
</LinearLayout>
<TextView android:id="#+id/no_photos"
android:layout_height="wrap_content"
android:layout_width="match_parent"
android:gravity="center"
android:textStyle="bold"
android:textSize="20dp"
android:text="#string/no_photos"
android:visibility="gone" />
<GridView android:id="#+id/grid_photos"
android:layout_width="match_parent"
android:layout_height="match_parent"
android:layout_margin="20dp"
android:columnWidth="120dp"
android:numColumns="auto_fit"
android:verticalSpacing="10dp"
android:horizontalSpacing="10dp"
android:stretchMode="columnWidth"
android:gravity="center" />
</LinearLayout>
And here is the result I got:
This is weird because the images are all cropped in a strange way like that. Below is one of my original images:
I've never encountered this problem so if any of you are familiar with this, please help me find the reason of this. Thank you!
P.s: I guess this can only be the problem of the xml layout so I don't think it is necessary to include my android source code here. But if it really is, please let me know where the problem may come from and I'll edit this question with my code.

The reason is GridView clears all the layout params set for the tiles and it set its own layout params so better you add your ImageView inside a RelativeLayout. This is the same with all the AdapterView like ListView,Gallery etc.

How to avoid space between imageview and gridview in linearlayout

I have a image view and grid view in my .xml file. When I am executing this file its getting some space between grid view and image view. How to avoid this space...can any one help me to solve this problem.
thanks in advance...
my xml code is:
android:layout_width="0px"
android:layout_height="0px">
</Button>
<LinearLayout
xmlns:android="http://schemas.android.com/apk/res/android"
android:orientation="horizontal"
android:layout_width="fill_parent"
android:layout_height="wrap_content">
<ImageView
android:id="#+id/prevMonth"
android:src="#drawable/cal_left_arrow_off2"
android:layout_width="wrap_content"
android:layout_height="wrap_content">
</ImageView>
<Button
android:id="#+id/currentMonth"
android:layout_weight="0.6"
android:textAppearance="?android:attr/textAppearanceMedium"
android:background="#drawable/calendar_bar2"
android:layout_width="wrap_content"
android:layout_height="wrap_content">
</Button>
<ImageView
android:id="#+id/nextMonth"
android:src="#drawable/cal_right_arrow_off2"
android:layout_width="wrap_content"
android:layout_height="wrap_content">
</ImageView>
</LinearLayout>
<LinearLayout
android:layout_gravity="bottom|center_horizontal"
android:layout_width="fill_parent"
android:layout_height="wrap_content">
<ImageView
android:id="#+id/calendarheader"
android:src="#drawable/blue_bg_with_text2"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
>
</ImageView>
</LinearLayout>
<GridView
android:id="#+id/calendar"
android:numColumns="7"
android:layout_gravity="top"
android:layout_width="fill_parent"
android:layout_height="wrap_content">
</GridView>

You should try setting the android:gravity attribute correctly, and it has to work:
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:orientation="vertical" android:layout_width="fill_parent"
android:layout_height="fill_parent">
<LinearLayout android:gravity="bottom|center_horizontal"
android:layout_width="fill_parent" android:layout_height="wrap_content">
<ImageView android:id="#+id/calendarheader" android:src="#color/blue_start"
android:layout_width="wrap_content" android:layout_height="wrap_content"
android:minWidth="250dp" android:minHeight="30dp">
</ImageView>
</LinearLayout>
<GridView android:id="#+id/calendar" android:numColumns="7"
android:layout_gravity="top"
android:layout_width="fill_parent" android:layout_height="wrap_content"
android:background="#color/blue_start">
</GridView>
</LinearLayout>
i'm using here simple color background, and there is no gap:
If you still having the problem, then you should see your blue_bg_with_text2 image, whether it has any empty pixels at the bottom.
ps: ignore the android:minWidth="250dp" android:minHeight="30dp" part, it is there to imitate an image with that size.
Update
Here is the same view using RelativeLayout (it's a bit clearer at least for me):
<?xml version="1.0" encoding="utf-8"?>
<RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:orientation="vertical" android:layout_width="fill_parent"
android:layout_height="fill_parent">
<Button android:id="#+id/selectedDayMonthYear"
android:textColor="#000000" android:layout_gravity="center"
android:textAppearance="?android:attr/textAppearanceMedium"
android:layout_width="0px" android:layout_height="0px" />
<ImageView android:id="#+id/prevMonth" android:src="#drawable/cal_left_arrow_off2"
android:layout_width="wrap_content" android:layout_height="wrap_content" />
<ImageView android:id="#+id/nextMonth" android:src="#drawable/cal_right_arrow_off2"
android:layout_width="wrap_content" android:layout_height="wrap_content"
android:layout_alignParentRight="true" />
<Button android:id="#+id/currentMonth" android:layout_weight="0.6"
android:textAppearance="?android:attr/textAppearanceMedium"
android:background="#drawable/calendar_bar2" android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:layout_toRightOf="#id/prevMonth"
android:layout_toLeftOf="#id/nextMonth"
android:layout_alignBottom="#id/prevMonth"
android:layout_alignTop="#id/prevMonth" />
<ImageView android:id="#+id/calendarheader" android:src="#drawable/calendarheader"
android:layout_width="fill_parent"
android:layout_height="wrap_content"
android:minHeight="25dp"
android:layout_centerInParent="true"
android:layout_below="#id/currentMonth"
android:layout_margin="0dp"
android:scaleType="fitXY" />
<GridView android:id="#+id/calendar" android:numColumns="7"
android:layout_gravity="top" android:layout_width="fill_parent"
android:layout_height="wrap_content"
android:layout_below="#id/calendarheader"
android:layout_margin="0dp"
android:background="#color/white_fader_end">
</GridView>
</RelativeLayout>
I've added to it my resources as background (two of them are actually screenshots from yours).
What i observed is, you must
either use a static image for your
calendar header background, or,
if you use an xml drawable, you have
to drop the stroke element from it / set its android:width to 0
otherwise it will add an unnecessary gap around your view's drawable, that is as wide as the stroke width you've specified.
my output using static images as backgrounds looks this way:
Update 2
The problem is not between your calendar header and gridView, but inside your gridView.
It has a 'padding' of 5 px inside (not real padding, see how it gets there):
The default selector for the GridView is a 9x9 patch rectangle with a border of 5px.
That 5 px is visible all around your gridView.
You can specify a different listSelector for this grid either by xml:
android:listSelector="#drawable/grid_selector"
or from code (onCreate):
gridView.setSelector(R.drawable.grid_selector);
Now if your grid_selector is an image or is a drawable xml without any margins, then the gap that causes the problem is gone.
You can also hide that gap, by setting a background color to your gridView, that matches or grandients the calendar header's background color.
