make a textview width proportional to imageview above - android

my layout is very simple. i use a vertical relative layout which contains an imageview on top of 2 textviews (heading and text). In portrait it looks fine. However in landscape it happens, that the imageview will not fill out the whole width of the screen but the text below still does. that doesnt look good. is there a simply way i can make the text width as wide as the imageview above, so all views will have the same right boarder on any screen size?
<?xml version="1.0" encoding="utf-8"?>
<ScrollView xmlns:android="http://schemas.android.com/apk/res/android">
<RelativeLayout
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:orientation="vertical"
>
<ImageView
android:id="#+id/imageView1"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:layout_centerHorizontal="true"
android:scaleType="fitStart"
android:adjustViewBounds="true"
android:src="#drawable/picture" />
<TextView
style="#style/DescriptionTitle"
android:id="#+id/textView1"
android:layout_alignLeft="#id/imageView1"
android:layout_below="#id/imageView1"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:text="#string/heading" />
<TextView
style="#style/DescriptionText"
android:id="#+id/textView2"
android:layout_alignLeft="#id/imageView1"
android:layout_below="#id/textView1"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:text="#string/text" />
</RelativeLayout>
</ScrollView>

Add android:layout_alignRight="#id/imageView1" to your TextView. You may need to use android:layout_width="0dp"; also on the same TextView.

insted of using android:src="#drawable/picture"
use android:background="#drawable/picture" hope it will work for you

Get rid of whitespace between Image and text in a vertical LinearLayout

I've an ImageView and 2 TextViews in a vertical LinearLayout.
<?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:paddingLeft="16dp"
android:paddingRight="16dp"
android:orientation="vertical" >
<ImageView
android:id="#+id/logo"
android:layout_width="100dp"
android:layout_height="100dp"
android:layout_gravity="center" />
<TextView
android:id="#+id/players"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:layout_marginTop="88dp"
android:maxLines="15"
android:text="TextView"
android:textStyle="bold" />
<TextView
android:id="#+id/subs"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:text="Subs" />
</LinearLayout>
I'm getting too much whitespace between the image and the text underneath it. The image is being resized in to the ImageView. I've changed background colours: And the image looks fine: taking up the expected space for the image and no more. From other questions, I've tried android:adjustViewBounds attribute for the ImageView but this hasn't made a difference.
The reason you are seeing white space is following attribute in players TextView:
android:layout_marginTop="88dp"
Either remove it or reduce the space as per your need.

Android: Align Parent Bottom + Bottom margin

I've used a relative layout and I want to set the button at bottom of the screen, However this puts it all the down to the bottom and I would like to have some margin so it there's some space between the end of the screen/view and the button. However whatever I do the button margin just doesn't do anything on 2.1+ for some reason. The relative layout contains a background so I cant but the margin on that.
Anyone know a fix for this?
<?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_marginBottom="0dp"
android:background="#drawable/background" >
<Button
android:id="#+id/confirm_mobile_button_next"
android:layout_width="fill_parent"
android:layout_height="40dip"
android:layout_alignParentBottom="true"
android:layout_alignParentLeft="false"
android:layout_centerHorizontal="false"
android:layout_centerInParent="false"
android:layout_margin="15dp"
android:background="#drawable/button_shape_selector"
android:paddingLeft="10dip"
android:paddingRight="10dip"
android:text="#string/confirm_mobile_no_continue"
android:textColor="#color/white"
android:textStyle="bold" />
</RelativeLayout>
You can simply add a padding to the RelativeLayout instead of a margin to the Button, e.g. android:paddingBottom="15dp".
In general I'm always testing my layout in the Exclipse preview using API Level 8 setting. This gives quite accurate results for most devices, including ICS and JB.
The other thing you can do is put a View that's aligned to the bottom of the RelativeLayout, and set its height to the bottom margin you would want to use (or simply specify a value for layout_marginBottom) like so:
<RelativeLayout
android:layout_width="wrap_content"
android:layout_height="wrap_content"
>
<ImageView
android:layout_width="match_parent"
android:layout_height="match_parent"
android:src="#drawable/some_image"
android:adjustViewBounds="true"
/>
<TextView
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:text="Some Overlay"
android:padding="3dip"
android:gravity="center_vertical|center_horizontal"
android:layout_above="#+id/empty_view"
android:layout_marginBottom="35dip"
/>
<View
android:id = "#+id/empty_view"
android:layout_height = "30dip"
android:layout_width = "match_parent"
android:visibility="invisible"
android:layout_alignParentBottom="true"
/>
</RelativeLayout>
This example fills the RelativeLayout with the ImageView, and positions a TextView over the ImageView.
Yu can use translateY attribute
translateY="-16dp"
Final code
<?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_marginBottom="0dp"
android:background="#drawable/background">
<Button
android:id="#+id/confirm_mobile_button_next"
android:layout_width="fill_parent"
android:layout_height="40dip"
android:layout_alignParentBottom="true"
android:layout_alignParentLeft="false"
android:layout_centerHorizontal="false"
android:layout_centerInParent="false"
android:layout_margin="15dp"
android:background="#drawable/button_shape_selector"
android:paddingLeft="10dip"
android:paddingRight="10dip"
android:text="#string/confirm_mobile_no_continue"
android:textColor="#color/white"
android:textStyle="bold"
android:translateY="-16dp" />
</RelativeLayout>
only working solution suggested by #franny zhao is below.
<?xml version="1.0" encoding="utf-8"?>
<RelativeLayout
android:layout_width="match_parent"
android:layout_height="wrap_content">
<FrameLayout
android:id="#+id/fl_layout"
android:layout_alignParentBottom="true"
android:layout_width="wrap_content"
android:layout_height="wrap_content">
<TextView
android:id="#+id/tv_layout"
android:text="hello world"
android:layout_marginBottom="50dp"
android:layout_width="wrap_content"
android:layout_height="wrap_content" />
</FrameLayout>
</RelativeLayout>
If you add padding to the bottom aligned view as suggested by others, the view background will also extend. If you have colored background then the view will look like it is glued to the bottom. Padding and margin are entirely different, padding is part of view, but margin leaves space between views.
I think the best way is to set android:layout_alignParentBottom in XML
then in java code behind:
Button confirm_mobile_button_next = (Button)findViewById(R.id.confirm_mobile_button_next)
and
confirm_mobile_button_next.setTransitionY(-THE_VALUE) or setTransitionX(-THE_VALUE)
I think the best way is to set:
<...
android:layout_alignParentBottom="true" />
then in java code behind:
Button confirm_mobile_button_next = (Button)findViewById(R.id.confirm_mobile_button_next)
confirm_mobile_button_next.setTransitionY(-THE_VALUE) or setTransitionX(-THE_VALUE)
You can use a ViewGroup(for example, FrameLayout or LinearLayout) to wrap the view. Set alignParentBottom in the outside ViewGroup, then marginBottom can work in the inside View.
<?xml version="1.0" encoding="utf-8"?>
<RelativeLayout
android:layout_width="match_parent"
android:layout_height="wrap_content">
<FrameLayout
android:id="#+id/fl_layout"
android:layout_alignParentBottom="true"
android:layout_width="wrap_content"
android:layout_height="wrap_content">
<TextView
android:id="#+id/tv_layout"
android:text="hello world"
android:layout_marginBottom="50dp"
android:layout_width="wrap_content"
android:layout_height="wrap_content" />
</FrameLayout>
</RelativeLayout>
Since I stumbled upon this issue, and saw no answers fit to my situation I started thinking for half a second and resolved it by setting a negative margin on the view inside the RelativeLayout sample:
<RelativeLayout
android:layout_width="match_parent"
android:layout_height="match_parent">
<ImageView
android:layout_width="48dp"
android:layout_height="48dp"
android:layout_marginTop="-8dp"
android:layout_marginStart="-8dp">
</RelativeLayout>
This should prove useful to some people.
Well this is 2022, but if you still are not using ConstraintLayout for some reason, like the one legacy project code I am fixing, use this property for a Bottom margin type visual.
android:translationY="-8dp"
and your code should look like this (in my case this a FAB in Relative Layout)
<com.google.android.material.floatingactionbutton.ExtendedFloatingActionButton
android:id="#+id/cart_check_out_btn"
style="#style/FABThemeDark"
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:layout_alignParentBottom="true"
android:layout_marginHorizontal="16dp"
android:layout_marginVertical="16dp"
android:text="#string/cart_check_out_btn"
android:textAllCaps="false"
android:translationY="-8dp" />
And it will work like this
Try in this way :
<RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android"
xmlns:tools="http://schemas.android.com/tools"
android:layout_width="fill_parent"
android:layout_height="fill_parent" >
<Button
android:id="#+id/button1"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:layout_alignParentBottom="true"
android:layout_centerHorizontal="true"
android:layout_marginBottom="17dp"
android:text="Button" />
Here is another alternative. If you want to set the child's margin instead of parent's padding, you should set the value of android:layout_marginTop to double of the desired margin and then set the android:layout_centerVertical to true. Top margin is given double the desired value to compensate the bottom margin. That way you will have an equal top and bottom margin around the child view.
<Button
android:id="#+id/confirm_mobile_button_next"
android:layout_width="fill_parent"
android:layout_height="40dip"
android:layout_alignParentBottom="true"
android:layout_alignParentLeft="false"
android:layout_centerVertical="true"
android:layout_centerInParent="false"
android:layout_marginLeft="15dp"
android:layout_marginRight="15dp"
android:layout_marginTop="30dp"
android:background="#drawable/button_shape_selector"
android:paddingLeft="10dip"
android:paddingRight="10dip"
android:text="#string/confirm_mobile_no_continue"
android:textColor="#color/white"
android:textStyle="bold" />
It will give you the same result.

Fit imageView and textView in one small layout in Android

I have a tiny linearlayout that I have to fit an imageView and a textView in. I know this is a terrible way to make an app. I'm just trying to test to see if this would work. The code below only shows the imageview and not the textView. Any ideas?
<?xml version="1.0" encoding="utf-8"?>
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:layout_width="wrap_content"
android:layout_height="wrap_content" >
<LinearLayout
android:layout_width="90dp"
android:layout_height="90dp"
android:orientation="vertical" >
<TextView
android:id="#+id/textView1"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:layout_weight="1"
android:text="TextView" />
<ImageView
android:id="#+id/imageView1"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:layout_weight="0"
android:src="#drawable/my_icon" />
</LinearLayout>
</LinearLayout>
The answer ended up being to give the textView a weight of 0 and the imageView a weight of 1. That way, textView showed up perfectly but only took as much space as it needed, and the imageView took up the rest of the space. Perfect1
It depends what you want it to look like. If you want the LinearLayout to be split in half, then in your ImageView set
android:layout_weight="1"
The views inside the LinearLayout get space in proportion to their layout_weight so if your ImageView has layout_weight="0" it will get 0 proportion of the View.
You should use weight like that:
android:layout_weight="2" in LinearLayout
and layout_weight="1" in imageView and textView
so that both of your view will occupy half of space
Please try this
<TextView
android:id="#+id/textView1"
android:layout_width="wrap_content"
android:layout_height="0dp"
android:layout_weight="1"
android:text="TextView" />
<ImageView
android:id="#+id/imageView1"
android:layout_width="wrap_content"
android:layout_height="0dp"
android:layout_weight="1"
android:src="#drawable/my_icon" />

How to let the ImageView and the TextView the same height

My layout have ImageView(iv) and TextView(tv).
I want to let the tv right of iv.
And the tv's height is same as iv's.
The tv Gravity set as CENTER_VERTICAL.
<?xml version="1.0" encoding="utf-8"?>
<RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:id="#+id/RelativeLayout1"
android:layout_width="match_parent"
android:layout_height="match_parent"
android:orientation="vertical" >
<ImageView
android:id="#+id/iv"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:layout_alignParentLeft="true"
android:layout_alignParentTop="true"/>
<TextView
android:id="#+id/tv"
android:layout_width="fill_parent"
android:layout_height="wrap_content"
android:layout_alignParentTop="true"
android:layout_toRightOf="#+id/iv"
android:text="TextView" android:gravity="center_vertical"/>
</RelativeLayout>
How to arrive the goal?
hi try this .....
<?xml version="1.0" encoding="utf-8"?>
<RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:id="#+id/RelativeLayout1"
android:layout_width="match_parent"
android:layout_height="match_parent"
android:orientation="vertical" >
<ImageView
android:id="#+id/iv"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:layout_alignParentLeft="true"
android:layout_alignParentTop="true"
android:src="#drawable/ic_title_home_demo" />
<TextView
android:id="#+id/tv"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:layout_alignBottom="#+id/iv"
android:layout_alignTop="#+id/iv"
android:layout_toRightOf="#+id/iv"
android:gravity="center_vertical"
android:text="TextView" />
</RelativeLayout>
You have to set the textview property to android:layout_alignTop="#id/iv" and android:layout_alignBottom="#id/iv"
Well to get it to center vertically correct, you will need to remove the android:layout_alignParentTop="true" line from your TextView tag.
However, it sounds like you might be trying to make the text change its size to fit the entire height of the ImageView. This obviously won't solve that, but I wouldn't recommend doing that in the first place as it could result in some strange looking views.
You can use distinct sizes by using
android:layout_width="wrap_content"
and /or
android:height="300dp"
(same for height). Also check margins and paddings.
If you need to be more dynamic, you might consider android:layout_weight i.e. for letting 2 buttons have equal width and fill the horizontal space of the parent view you would set:
android:layout_height="wrap_content"
android_layout:weight="0.5".

Android RelativeLayout

I'm very new to Android development and I'm trying to figure out how to use the RelativeLayout tag to position my Views. My goal is to have a large TextView on the left, with two ButtonViews to the right of it, stacked on top of each other. Here's the XML code I'm using:
<?xml version="1.0" encoding="utf-8"?>
<RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:id="#+id/main_layout"
android:layout_width="fill_parent"
android:layout_height="fill_parent"
android:background="#drawable/wood_tile">
<TextView
android:id="#+id/life_counter"
android:layout_width="fill_parent"
android:layout_height="wrap_content"
android:text="00" />
<Button android:text="#string/button_up"
android:id="#+id/button_up"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:layout_toRightOf="#id/life_counter"/>
<Button android:text="#string/button_down"
android:id="#+id/button_down"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:layout_below="#id/button_up"/>
</RelativeLayout>
I feel that I must not be using the tag properly. Can someone explain how it works? Thanks in advance.
You have the left side TextView's width set to fill_parent, this will make it consume the entire screen. Anything placed to the right of it will be off screen. Use wrap_content or a specific width for the elements within the relative layout.
Your approach is also a bit off. If you want the two buttons aligned to the right of the screen, use this:
<RelativeLayout
android:id="#+id/main_layout"
android:layout_width="fill_parent"
android:layout_height="fill_parent">
<TextView
android:id="#+id/life_counter"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:text="00" />
<Button android:text="Button Up"
android:id="#+id/button_up"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:layout_alignParentRight="true"/>
<Button android:text="Button Down"
android:id="#+id/button_down"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:layout_alignParentRight="true"
android:layout_below="#+id/button_up"/>
</RelativeLayout>
