Setting View Height In Relative Layout - android

I have a layout like this in which I want to display a label above a view and then repeat it below.
Here is my code...
<RelativeLayout
android:layout_width="0dp"
android:layout_height="match_parent"
android:layout_weight="1"
android:orientation="vertical" >
<TextView
android:id="#+id/speedLbl"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:layout_marginLeft="20dp"
android:text="#string/speed"
android:textAppearance="?android:attr/textAppearanceLarge" />
<View
android:id="#+id/speedGraph"
android:layout_width="fill_parent"
android:layout_height="match_parent"
android:layout_marginBottom="4dp"
android:layout_below="#+id/speedLbl"
android:layout_marginLeft="20dp"
android:layout_marginRight="20dp"
android:background="#color/blueColour" />
<TextView
android:id="#+id/distanceLbl"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:layout_marginLeft="20dp"
android:layout_below="#+id/speedGraph"
android:text="#string/distance"
android:textAppearance="?android:attr/textAppearanceLarge" />
<View
android:id="#+id/distanceGraph"
android:layout_width="fill_parent"
android:layout_height="match_parent"
android:layout_below="#+id/distanceLbl"
android:layout_marginBottom="4dp"
android:layout_marginLeft="20dp"
android:layout_marginRight="20dp"
android:background="#color/blueColour" />
</RelativeLayout>
The problem is I don't want to set a height for the two views as I want them to dynamically change depending on the screen size. I tried using layout_weight but it doesn't like the fact that its nested inside another.
Can anyone see another solution for this problem??

You could avoid the double weights issue with a small trick. You could set an empty View at the vertical center of the parent RelativeLayout and position the two groups above and below that View, something like this:
<RelativeLayout
android:layout_width="0dp"
android:layout_height="match_parent"
android:layout_weight="1"
android:orientation="vertical" >
<View android:id="#+id/anchor"
android:layout_width="fill_parent"
android:layout_height="0dp"
android:layout_centerVertical="true/>
<TextView
android:id="#+id/speedLbl"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:layout_marginLeft="20dp"
android:text="#string/speed"
android:textAppearance="?android:attr/textAppearanceLarge" />
<View
android:id="#+id/speedGraph"
android:layout_width="fill_parent"
android:layout_height="match_parent"
android:layout_marginBottom="4dp"
android:layout_below="#id/speedLbl"
android:layout_above="#id/anchor"
android:layout_marginLeft="20dp"
android:layout_marginRight="20dp"
android:background="#color/blueColour" />
<TextView
android:id="#+id/distanceLbl"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:layout_marginLeft="20dp"
android:layout_below="#id/anchor"
android:text="#string/distance"
android:textAppearance="?android:attr/textAppearanceLarge" />
<View
android:id="#+id/distanceGraph"
android:layout_width="fill_parent"
android:layout_height="match_parent"
android:layout_below="#id/distanceLbl"
android:layout_alignParentBottom="true"
android:layout_marginBottom="4dp"
android:layout_marginLeft="20dp"
android:layout_marginRight="20dp"
android:background="#color/blueColour" />
</RelativeLayout>
Also you should use the #+id/... notation only when you first declare that id, on the next id occurrence you should use #id/....

You can achieve the dynamic screen size through layout_weight . But before that you just try layout_weight to the Linear Layout and provide the appropriate weights to the view and textview. It almost solve your problem. Dont use Relative Layout with Weight. weight is not working in Relative layout.

How to create a paragraph in android studio?

I want to create a layout of the list item as shown in the image.I divided it into three parts taking whole layout as Linear(orientation-horizontal).Three parts are
1) Image
2) Paragraph
3) three edit text in a linear layout.
I have problem in the second part as the length of paragraph (Text View) it disturbs the next part.I also try by putting weight in relative layout but it does not work.What is the solution for this problem?
How to do something like this.
Code:
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:orientation="horizontal"
android:layout_width="match_parent"
android:layout_height="match_parent">
<ImageView
android:id="#+id/item_icon"
android:src="#drawable/hammer"
android:layout_weight="1"
android:layout_width="100dp"
android:layout_height="wrap_content" />
<TextView
android:id="#+id/item_name"
android:layout_toRightOf="#id/item_icon"
android:layout_weight="1"
android:text="skvnksjdjbkjbkjb"
android:layout_width="wrap_content"
android:layout_height="wrap_content" />
<LinearLayout
android:id="#+id/item_detail"
android:layout_toRightOf="#id/item_name"
android:layout_weight="1"

android:layout_width="wrap_content"
android:layout_height="wrap_content">
<TextView
android:id="#+id/detail1"
android:layout_weight="1"
android:text="fkvjbfvkjbv"
android:textSize="20dp"
android:layout_width="wrap_content"
android:layout_height="wrap_content" />
<TextView
android:id="#+id/detail2"
android:layout_weight="1"
android:text="fkvjbfvkjbv"
android:textSize="20dp"
android:layout_width="wrap_content"
android:layout_height="wrap_content" />
<TextView
android:id="#+id/detail3"
android:layout_weight="1"
android:text="fkvjbfvkjbv"
android:textSize="20dp"
android:layout_width="wrap_content"
android:layout_height="wrap_content" />
</LinearLayout>
</LinearLayout>
if you use layout_weight, the layout_width (for horizontal LinearLayouts) should be set to 0dp

Put a textview over Imageview in LinearLayout

I have stuck in some xml code and i hope you can help me out.
So here is what I need/what I have done by now.
I have 3 images of 650px width and I need them one below another while keeping aspect ratio.
I did that with the following code and it looks as it should. No problem here.
<LinearLayout
xmlns:android="http://schemas.android.com/apk/res/android"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:id="#+id/ll"
android:orientation="vertical"
android:background="#3afa3f"
android:weightSum="3">
<ImageView
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:id="#+id/krk_history"
android:layout_weight="1"
android:background="#drawable/povjestkrka_vintage_yellow600" />
<ImageView
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:layout_weight="1"
android:id="#+id/krk_frankopan"
android:background="#drawable/frankopan2_vintage_sundown600" />
<ImageView
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:layout_weight="1"
android:id="#+id/krk_turizam"
android:background="#drawable/krk_turizam_vintage"/>
The problem is. I need to put three textviews in a left bottom corner of each image. Imagine it like image menu with text description on each image.
So, I can not use relative or frame layout because images won't play nicely with each other :) There is always a gap between or not aspect ration etc. I need weightsum.
Second, I can't hardcode the text on each image in photoshop because the app will be translated and text needs to change for each language.
I can have different images for each language but I am trying to avoid that.
Ah yea, one more last thing.
I tried to put entire linearlayout in relative layout and put the text between but the text appears beneath the image and I can't bring it upfront.
Any suggestions?
Thanks a lot,
Xsonz
just copy this :
<?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"

Take three FrameLayout inside your LinearLayout and inside FrameLayout keep the ImageView and TextView.
Or Else You can use RelativeLayout and give dependency to Views
You can use frame layout inside linear layout. create imageview inside the linear layout and create textview in another frame layout below it.
<FrameLayout
android:id="#+id/frameLayout_image"
android:layout_width="wrap_content"
android:layout_height="wrap_content">
<ImageView
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:id="#+id/krk_history"
android:layout_weight="1"
android:background="#drawable/povjestkrka_vintage_yellow600" />
</FrameLayout>
<FrameLayout
android:id="#+id/frameLayout_text"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:layout_marginTop="-5dp" >
<TextView
android:id="#+id/text"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:gravity="center"
android:text="string" />
</FrameLayout>
Something like this might work for you.
//your layout -> LinearLayout>
....
<RelativeLayout android:layout_width="wrap_content"
android:layout_height="wrap_content">
<ImageView android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:id="#+id/image1"
android:layout_weight="1"
android:background="#drawable/A1" />
<TextView android:id="#+id/textview1"
android:layout_margin="0dp"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:text="My Text"
android:layout_below="#id/image1"
android:layout_alignLeft="#id/image1" />
</RelativeLayout>
// end your LinearLayout
You can play with these parameters using Relative Layout Parameters android.com. The relative layout allows you to control the "relative" positioning between your elements.
You can lay your images out side by side, or in whatever fashion you wish.
Then you can adjust the text dynamically.

Align multipile images evenly horizontaly

I have 2 image views in a linear layout like so:
<LinearLayout
style="#style/home_icon_row"
android:orientation="horizontal">
<ImageView
android:id="#+id/ibtn_home_bus"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:src="#drawable/ico_bus_selector" />
<ImageView
android:id="#+id/ibtn_home_butoday"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:src="#drawable/ico_butoday_selector" />
</LinearLayout>
How can i align the two images so that they are evenly placed within the linear layout. Something similar to "justified text" so that it has equal spacing on the left and right of the image from each other and the border of the screen.
it's not the best solution, but it should work:
<LinearLayout
style="#style/home_icon_row"
android:orientation="horizontal">
<View
android:layout_width="0dp"
android:layout_weight="1"
android:layout_height="0dp"
android:enable="false"
android:focussable="false"
android:clickable="false"
/>
<ImageView
android:id="#+id/ibtn_home_bus"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:src="#drawable/ico_bus_selector" />
<View
android:layout_width="0dp"
android:layout_weight="1"
android:layout_height="0dp"
android:enable="false"
android:focussable="false"
android:clickable="false" />
<ImageView
android:id="#+id/ibtn_home_butoday"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:src="#drawable/ico_butoday_selector" />
<View
android:layout_width="0dp"
android:layout_weight="1"
android:layout_height="0dp"
android:enable="false"
android:focussable="false"
android:clickable="false" />
</LinearLayout>
if this is for some kind of landing it's ok but if it's a hard used layout think about implementing it dinamically via javacode to make it faster.
EDIT: i added 3 attributes ( enable, focussable, clickable ) to disable the placehodler view so that they'll be considered only at measures/layout time, but not during events handling.
// try this way here is alternative to use two sub linear layout rather three View.
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
style="#style/home_icon_row"
android:layout_width="match_parent"
android:layout_height="wrap_content">
<LinearLayout
android:layout_width="0dp"
android:layout_height="wrap_content"
android:layout_weight="1"
android:gravity="center">
<ImageView
android:id="#+id/ibtn_home_bus"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:src="#drawable/ico_bus_selector" />
</LinearLayout>
<LinearLayout
android:layout_width="0dp"
android:layout_height="wrap_content"
android:layout_weight="1"
android:gravity="center">
<ImageView
android:id="#+id/ibtn_home_butoday"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:src="#drawable/ico_butoday_selector" />
</LinearLayout>
</LinearLayout>
You should be able to get similar effect by using layout_width="0dp", layout_weight="1" and scaleType="centerInside" for both ImageViews.
The only difference is that space between the images can be bigger.
<LinearLayout
style="#style/home_icon_row"
android:orientation="horizontal"
android:padding="#dimen/padding">
<ImageView
android:id="#+id/ibtn_home_bus"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:src="#drawable/ico_bus_selector"
android:layout_marginRight="#dimen/padding"/>
<ImageView
android:id="#+id/ibtn_home_butoday"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:src="#drawable/ico_butoday_selector" />
</LinearLayout>

android child layout not showing

I have a LinearLayout with three RelativeLayout inside. The first two children layouts show. The third one does not show. When I change the children from RelativeLayout to LinearLayouts, the third one still does not show. Any ideas on how to fix this? The one not showing contains the ImageView.
Here is the code:
<?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="60dp"

android:layout_alignParentRight="true"
android:src="#drawable/guess" />
</RelativeLayout>
</LinearLayout>
Your second Relative Layout's height is
android:layout_height="match_parent"
try putting:
android:layout_height="wrap_content"
--edit - try adding a weight attribute.
</RelativeLayout>
<RelativeLayout
android:weight=1
>
</RelativeLayout>
<RelativeLayout
android:weight=1>
</RelativeLayout>
android:layout_centerInParent="true" remove this from the view, if you want to add a view you can add separately out of the RelativeLayout with this your Layout is already in the center of the parent, For debug purpose set the width of each view to certain level so that you can see. Your two RelativeLayout already took the width of the Linear Layout, so no space left for the third Layout.
I decide to do it programmatically. I get the width of the device using context.getResources().getDisplayMetrics().widthPixels. Then from there I layout my pieces pixels by pixels, so to speak.

Custom dialog height to match content

This is my custom dialog, there are some textboxs and two buttons.
I'm using a RelativeLayout on it.
I'd like the dialog size to match the content, not all that blank space under there.
I don't want to use explicit pixel heights (it's not good practice).
Another thing, there's a way to have some space between every view?
This is my XML
<RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:layout_width="fill_parent"
android:layout_height="fill_parent">
<TextView
android:id="#+id/txt_desc"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:textSize="8pt"
android:textStyle="italic" />
<TextView
android:id="#+id/txt_date"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:layout_marginLeft="10dp"
android:layout_below="#+id/txt_desc"
android:textSize="8pt" />
<TextView
android:id="#+id/txt_place"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:layout_marginLeft="10dp"
android:layout_below="#+id/txt_date"
android:textSize="8pt" />
<Button
android:id="#+id/btn_close"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:layout_alignParentRight="true"
android:layout_below="#+id/txt_place"
android:layout_toRightOf="#+id/view"
android:text="#string/btn_close" />
<View
android:id="#+id/view"
android:layout_width="0dp"
android:layout_height="1dp"
android:layout_centerHorizontal="true" />
<Button
android:id="#+id/btn_edit"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:layout_alignParentLeft="true"
android:layout_below="#+id/txt_place"
android:layout_toLeftOf="#+id/view"
android:drawableLeft="#android:drawable/ic_menu_edit"
android:text="#string/btn_edit" />
</RelativeLayout>
First question
<RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:layout_width="wrap_content"
android:layout_height="wrap_content">
Second question
Plus use android:marginTop="5dp" if you want to separate a View from Top for 5 dp.
marginLeft|Right|Bottom are also available.
<TextView
android:id="#+id/txt_place"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:layout_marginLeft="10dp"
android:layout_marginTop="5dp" <-----------------
android:layout_below="#+id/txt_date"
android:textSize="8pt" />
By the way, if I were you, I'd nest some layouts to make order. You can have a general Relative Layout, then 2 linear layouts: one horizontal for TextViews and one vertical for Buttons. You can definely play with your editor and try to make the best appearance for your dialog.
EDIT
Try this one:
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:layout_width="match_parent"
android:layout_height="match_parent"
android:background="#0000"
android:orientation="vertical"
android:paddingBottom="50dp" >
<LinearLayout
android:orientation="vertical"
android:layout_width="wrap_content"
android:layout_height="wrap_content" >
<LinearLayout
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:orientation="vertical" >
<TextView
android:id="#+id/txt_desc"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:text="prova"
android:textSize="8pt"
android:textStyle="italic" />
<TextView
android:id="#+id/txt_date"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:layout_marginLeft="10dp"
android:text="prova"
android:textSize="8pt" />
<TextView
android:id="#+id/txt_place"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:layout_marginLeft="10dp"
android:text="prova"
android:textSize="8pt" />
</LinearLayout>
<LinearLayout
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:orientation="vertical" >
<Button
android:id="#+id/btn_edit"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:drawableLeft="#android:drawable/ic_menu_edit"
android:text="btn_edit" />
<Button
android:id="#+id/btn_close"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:text="btn_close" />
<View
android:id="#+id/view"
android:layout_width="0dp"
android:layout_height="1dp" />
</LinearLayout>
</LinearLayout>
</LinearLayout>
I've hard-coded the texts. The main idea is to use a big container layout in background, which is trasparent (background=#0000) and in top of that a layout in wrap_content containing your Views.
If this solution doesn't resolve your problem, I think you could edit height directly in your code. Try to relate to this question
Set your relative layout's height to wrap_content.
For example:
<RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:layout_width="match_parent"
android:layout_height="wrap_content">
<!-- More XML -->
</RelativeLayout>
Also be aware that fill_parent is deprecated for widths and heights.
You can add either margin (extra space outside a view) or padding (extra space inside a view) with android:layout_margin or android:padding respectively. There are also variants such as layout_marginTop that only apply to a specific side of the view.
