How to put an ImageView inside a CardView with border radius top?

My xml is as follows:
<?xml version="1.0" encoding="utf-8"?>
<android.support.v7.widget.CardView xmlns:android="http://schemas.android.com/apk/res/android"
xmlns:app="http://schemas.android.com/apk/res-auto"
android:id="#+id/recyclerMainCardView"
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:layout_marginTop="18dp"
app:cardElevation="10dp">
<LinearLayout
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:orientation="vertical">
<ImageView
android:id="#+id/imgRecyclerMain"
android:layout_width="match_parent"
android:layout_height="100dp"
android:fitsSystemWindows="true"
android:scaleType="centerCrop" />
<LinearLayout
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:layout_margin="10dp"
android:orientation="vertical"
android:weightSum="5">
<TextView
android:id="#+id/txtRecyclerMainTheme"
android:layout_width="match_parent"
android:layout_height="0dp"
android:layout_weight="3"
android:textSize="20sp" />
<LinearLayout
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:layout_gravity="end"
android:layout_weight="2"
android:orientation="horizontal">
<TextView
android:id="#+id/txtRecyclerMainNumberCommunity"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:layout_marginEnd="8dp"
android:textSize="14sp" />
<TextView
android:id="#+id/txtRecyclerMainNumberArticles"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:textSize="14sp" />
</LinearLayout>
</LinearLayout>
</LinearLayout>
</android.support.v7.widget.CardView>
That is my recycler_main_themes.xml which in inside a recycler view to display themes. The behavior of the image I'm looking for is to have the card with both left and right borders with 8dp radius, so I've put inside the MainActivity this:
cardView.setBackgroundResource(R.drawable.card_view_border);
And this is the card_view_border.xml:
<?xml version="1.0" encoding="utf-8"?>
<shape xmlns:android="http://schemas.android.com/apk/res/android">
<solid android:color="#color/white" />
<corners android:topLeftRadius="10dp" android:topRightRadius="10dp" />
</shape>
But when the app runs, before the image is displayed, the cardView has both top borders with the radius then after the image is downloaded, the imageView overlaps the cardView and the card looks rectangular. Picture of how it is:
What am I missing to display it properly?
Edit: just to complement, I've tried many things such as changing the ImageView scaleType to fitXY, set setPreventCornerOverlap(false) on CardView, changing cardElevation on CardView and putting elevation on ImageView, but none succeeded.

How do I get a line to wrap around textview without passing through the text?

I am planning to achieve something like this:
---------------Text---------------
where "-----" is actually a line ,(view line perhaps? or a divider) .
more accurately, this is an example of what i am trying to achieve:
I was wondering how do I achieve that in my textview. here's my layout:
<RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:layout_width="wrap_content"
android:layout_height="wrap_content">
<TextView
android:id="#+id/mydate"
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:gravity="center"
android:textColor="#android:color/darker_gray"
android:textSize="18sp"/>
</RelativeLayout>

You can do this by creating a single, full-width line, and then putting the TextView on top of it. If you give the TextView the same background color as the parent's background, and give the TextView some left and right padding, it will look like you example.
You can use this for the line (line.xml in your res/drawable directory) :
<?xml version="1.0" encoding="utf-8"?>
<shape
xmlns:android="http://schemas.android.com/apk/res/android"
android:shape="line"
>
<stroke
android:color="#android:color/darker_gray"
android:width="1dp"
/>
</shape>
and then use this layout:
<FrameLayout
android:layout_width="match_parent"
android:layout_height="wrap_content"
>
<ImageView
android:layout_width="match_parent"
android:layout_height="10dp"
android:src="#drawable/line"
android:layout_gravity="center"
/>
<TextView
android:id="#+id/mydate"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:layout_gravity="center"
android:paddingLeft="10dp"
android:paddingRight="10dp"
android:background="#android:color/white"
android:textColor="#android:color/darker_gray"
/>
</FrameLayout>

Styling Linear Layout with multi edit text

I am trying to make a LinearLayout with several EditText for inputting fields like this:
I checked several answers here to make a custom drawable for the EditText but how can I make it for the whole linear layout?

You can't do this with a single LinearLayout.
You need minimum 2 LinearLayouts with horizontal orientation, and one LinearLayout with vertial orientation, that contains those two.
And you can set the borders for your EditTexts with shape Drawables.
See examples here: How to draw rounded rectangle in Android UI?

Try below code ,You can also inclue textview inside it,
<?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:layout_width="match_parent"
android:layout_height="wrap_content"
android:orientation="horizontal" >
<EditText
android:layout_width="0dp"
android:layout_height="wrap_content"
android:layout_weight="0.55"
android:background="#drawable/selector"/>
<EditText
android:layout_width="0dp"
android:layout_height="wrap_content"
android:layout_weight="0.15"
android:background="#drawable/selector"/>
<EditText
android:layout_width="0dp"
android:layout_height="wrap_content"
android:layout_weight="0.30"
android:background="#drawable/selector"/>
</LinearLayout>
<LinearLayout
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:orientation="horizontal"
>
<EditText
android:layout_width="0dp"
android:layout_height="wrap_content"
android:layout_weight="0.20"
android:background="#drawable/selector"/>
<EditText
android:layout_width="0dp"
android:layout_height="wrap_content"
android:layout_weight="0.20"
android:background="#drawable/selector"/>
<EditText
android:layout_width="0dp"
android:layout_height="wrap_content"
android:layout_weight="0.60"
android:background="#drawable/selector" />
</LinearLayout>
</LinearLayout>
where selector drawable is xml file inside xml folder
selector.xml
<?xml version="1.0" encoding="utf-8"?>
<shape
xmlns:android="http://schemas.android.com/apk/res/android"
android:shape="rectangle">
<solid android:color="#android:color/white" />
<stroke
android:width="1dp"
android:color="#android:color/black"
/>
<padding
android:left="5dp"
android:right="5dp"
android:top="5dp"
android:bottom="5dp" />
</shape>

why there is some space in this layout?

I use this code for making 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="match_parent"
android:layout_margin="20dp"
android:background="#android:color/transparent">
<LinearLayout
android:layout_height="wrap_content"
android:layout_width="match_parent"
android:orientation="vertical"
android:layout_centerInParent="true"
android:background="#drawable/rounded_white_bg">
<EditText
android:id="#+id/login"
android:layout_height="wrap_content"
android:layout_width="match_parent"
android:background="#drawable/dialog_edittex"
android:layout_margin="10dp"/>
<EditText
android:id="#+id/password"
android:layout_height="wrap_content"
android:layout_width="match_parent"
android:layout_margin="10dp"
android:background="#drawable/dialog_edittex"/>
<TextView
android:layout_height="wrap_content"
android:layout_width="wrap_content"
android:textColor="#android:color/black"
android:text="AAAAAAAAAAAA"
android:layout_gravity="center"
android:textSize="20sp"
/>
<ImageView
android:layout_height="wrap_content"
android:layout_width="match_parent"
android:src="#drawable/dialog_button_bg"/>
</LinearLayout>
</RelativeLayout>
rouded_whiite.bg.xml
<shape xmlns:android="http://schemas.android.com/apk/res/android">
<solid android:color="#ffffff" />
<corners
android:radius="20dp"/>
</shape>
But when I do this I have see this result. As you can see there is some margin below of red button. I didn't set any margin or something but there is some space there. What should I do here for getting exact result as in fist image.

Remove the margin from your RelativeLayout and make your LinearLayout gravity android:layout_centerHorizontal="true"
<RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:layout_width="match_parent"
android:layout_height="match_parent"
android:background="#android:color/transparent">
<LinearLayout
android:layout_height="wrap_content"
android:layout_width="match_parent"
android:orientation="vertical"
android:layout_centerHorizontal="true"
android:background="#drawable/rounded_white_bg">

Use :
android:layout_centerHorizontal="true"
instead of
android:layout_centerInParent="true"
and remove margin from bottom...

<LinearLayout
android:layout_height="wrap_content"
it is because of this. remove the imageview from the linear layout and set in the relative layout and give property as alignparent bottom and for the linear layout give alignparent top and above the image view property,

Try This
<RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:layout_width="match_parent"
android:layout_height="match_parent"
android:layout_marginTop="20dp"
android:background="#android:color/transparent">
<LinearLayout
android:layout_height="wrap_content"
android:layout_width="match_parent"
android:orientation="vertical"
android:background="#drawable/rounded_white_bg">
<EditText
android:id="#+id/login"
android:layout_height="wrap_content"
android:layout_width="match_parent"
android:background="#drawable/dialog_edittex"
android:layout_margin="10dp"/>
<EditText
android:id="#+id/password"
android:layout_height="wrap_content"
android:layout_width="match_parent"
android:layout_margin="10dp"
android:background="#drawable/dialog_edittex"/>
<TextView
android:layout_height="wrap_content"
android:layout_width="wrap_content"
android:textColor="#android:color/black"
android:text="AAAAAAAAAAAA"
android:layout_gravity="center"
android:textSize="20sp"
/>
<ImageView
android:layout_height="wrap_content"
android:layout_width="match_parent"
android:src="#drawable/dialog_button_bg"/>
</LinearLayout>
</RelativeLayout>

If your using drawable for imageview as .png or .jpg use the following drawable for your image may be it would help. save this as backgroung_bg.xml or anything else as you wish
<selector xmlns:android="http://schemas.android.com/apk/res/android" >
<item >
<shape >
<corners android:bottomLeftRadius="20dp"
android:bottomRightRadius="20dp"
android:topLeftRadius="0dp"
android:topRightRadius="0dp"/>
<solid android:color="#CF4647"/>
<padding android:left="5dp"
android:top="5dp"
android:right="5dp"
android:bottom="5dp"/>
</shape>
</item>
when you apply this you would get following warning just ignore and run it. if you need gradient type of color ask me
The graphics preview in the layout editor may not be accurate:
Different corner sizes are not supported in Path.addRoundRect. (Ignore for this session)

Android List Item: TextView on left, Image on right

I'm creating a custom list item in and android list view. it's very simple, it has a textview on the left and an image on the right. the image should align all the way right, and the text view should take up all the space on the left. problem is, i can get the image to show up, but it pushes left. if i set the textview width to fill_parent, the image disappears. here's my layout:
<?xml version="1.0" encoding="utf-8" ?>
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android" android:orientation="horizontal"
android:layout_width="fill_parent" android:layout_height="50px" android:layout_gravity="center_vertical">
<!-- item -->
<TextView android:id="#+id/txtItem" android:gravity="center_vertical" android:textSize="20px" android:layout_width="fill_parent"
android:layout_height="fill_parent"/>
<!-- disclosure image -->
<ImageView android:layout_gravity="right|center_vertical" android:src="#drawable/common_icon_arrow_disclosure"
android:layout_width="wrap_content" android:layout_height="wrap_content"/>
</LinearLayout>
i've also tried a relative layout, but the same thing happens. what am i doing wrong?
EDIT: for clarification, this is what i'm trying to accomplish:
i want the text field to take up the whole left area, and the image to be on the right, unscaled, vertically centered.

You can also just add the drawable to the textview directly like this.
<TextView
android:id="#+id/txtItem"
android:layout_width="fill_parent"
android:layout_height="fill_parent"
android:drawableRight="#drawable/common_icon_arrow_disclosure"
android:gravity="center_vertical"
android:textSize="20px" />

You can use bitmap drawable like this (this also adds rounded corners):
<layer-list xmlns:android="http://schemas.android.com/apk/res/android">
<item>
<shape>
<solid android:color="#android:color/white" />
<stroke
android:width="2dp"
android:color="#adadad"
/>
<corners android:radius="5dp" />
</shape>
</item>
<item android:right="5dp"
android:top="2dp"
android:bottom="2dp">
<bitmap
android:src="#drawable/image"
android:gravity="right"
/>
</item>
</layer-list>
and put this drawable in background property of your TextView:
<TextView
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:background="#drawable/right_image"
android:text="some text"
/>

Left-align your text with the parent, and set the gravity of the image to right:
<?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="48dp">
<TextView
android:id="#+id/team_member_name"
android:layout_width="wrap_content"
android:layout_height="fill_parent"
android:layout_alignParentLeft="true"
android:gravity="center_vertical"
android:singleLine="true"/>
<ImageView
android:id="#+id/team_member_icon"
android:layout_alignParentRight="true"
android:layout_width="wrap_content"
android:layout_height="fill_parent"
android:layout_gravity="right"
android:layout_marginLeft="8dp"
android:layout_marginRight="8dp"
android:src="#drawable/circle_green"/>
</RelativeLayout>

Relative layout is what you want. In your case the fill_parent attribute was causing the text view to push the image off of the screen. If you use Relative layout and set the text view to use the layout_toLeftOf it should work.
Here is a quick example that I think will work (I haven't tested it out and it's from memory but the idea is there)...
<RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:layout_width="fill_parent"
android:layout_height="50px"
android:layout_gravity="center_vertical">
<ImageView android:id="#+id/img"
android:layout_gravity="right|center_vertical"
android:src="#drawable/common_icon_arrow_disclosure"
android:layout_width="wrap_content"
android:layout_height="wrap_content"/>
<TextView android:id="#+id/txtItem"
android:gravity="center_vertical"
android:textSize="20px"
android:layout_width="wrap_content"
android:layout_height="fill_parent"
android:layout_toLeftOf="#id/img" />
</RelativeLayout>

This worked for me:
<RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:orientation="horizontal"
android:layout_width="fill_parent"
android:layout_height="fill_parent" >
<TextView android:id="#+id/date"
android:layout_width="wrap_content"
android:layout_height="fill_parent"
android:padding="10dp"
android:layout_marginRight="10dp"
android:textSize="16sp"
android:textColor="#color/text_color"
android:layout_alignParentLeft="true"
android:gravity="center_vertical"/>
<ImageView android:id="#+id/imageBtn"
android:layout_width="wrap_content"
android:layout_height="fill_parent"
android:padding="10dp"
android:contentDescription="#string/delete"
android:src="#drawable/delete_minus_png"
android:layout_alignParentRight="true" />
</RelativeLayout>
Line android:layout_marginRight="10dp" did the trick.
Hope it helps!

Looks like there is some layout bug or so. If the TextView has fill_parent flag, the ImageView will be pushed away from the layout, even if the TextView contents are small enough.
