I don't exactly know what the issue is but just to clarify on a few things:
I'm using LinearLayout
My goal is to make a text string "example" go below an EditText view and it seems that whenever I try using margins to move the views and try to center them they always end up going the opposite way from each other, do you guys have any suggestions to fix this?
you can use Relativelayout as parent Layout and position your widgets relative to each other using their id
you can put this code in your textview xml definition
layout_below:#id/the one above it
LinearLayout
Defined android:orientation:vertical, allows you to position in list form each view that you add
<LinearLayout
android:layout_width="match_parent"
android:layout_height="match_parent"
android:orientation="vertical">
<EditText
android:id="#+id/edit_text"
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:inputType="textAutoComplete"/>
<TextView
android:id="#+id/text_view"
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:text="Message"/>
</LinearLayout>
RelativeLayout
Defined android:layout_below="id_view" where id_view is the id of the view that would go first
<RelativeLayout
android:layout_width="match_parent"
android:layout_height="match_parent">
<EditText
android:id="#+id/edit_text"
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:inputType="textAutoComplete"/>
<TextView
android:layout_below="#id/edit_text"
android:id="#+id/text_view"
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:text="Message"/>
</RelativeLayout>

I have a TextView within a ScrollView all wrapped in a LinearLayout and the end of the TextView is getting cutoff (multiple lines).
This is the XML:
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:orientation="vertical"
android:layout_width="match_parent"
android:layout_height="match_parent"
android:baselineAligned="false">
<ScrollView
android:layout_width="match_parent"
android:layout_height="wrap_content">
<TextView
android:id="#+id/tv_description"
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:padding="8dp"
android:text=""
android:textSize="10dp"
android:layout_weight="1"
android:layout_gravity="fill_vertical" />
</ScrollView>
</LinearLayout>
The TextView is cutting off regardless of whether the pane scrolls or not and it's driving me mad! Any help?!
<ScrollView
android:layout_width="match_parent"
android:layout_height="match_parent">//try this
if this doesnt solve the problem then:-
also you can try using ScrollView as a parent view.No need of that Linear layout if it just contains a single child(TextView)
Update. I 'fixed' the issue by changing the type of the fragment to work as a RecyclerFragment. Which when the fragment is added to the rest of the structure stops the cut-off!
I've inherited this app mid-development and the hand-over was...finish this app and fix the bugs, so I am finding my way through wearing a blindfold!
Thanks anyway!
I have a dialog fragment that contains linear layout that involves a titleText above a RecyclerView, and at the very bottom, there's a button below the recyclerView.
Since a recyclerView expands or collapses based on the number of items the adapter sets, the button sometimes gets truncated and no longer appears to be on screen, since the recyclerView just covers the entire screen.
My question is, is there a way to set the maximum height of the recyclerView without ever hiding the button underneath. I also don't want to just give the view a random height just in case the recyclerView contains no items, and it would just be a blank section.
Please let me know if you've ever run into this issue, and how you resolved this. Thanks!
UPDATED
You can achieve this easily using layout weights. Here's an example:
<?xml version="1.0" encoding="utf-8"?>
<FrameLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:layout_width="match_parent"
android:layout_height="match_parent">
<LinearLayout
android:layout_width="match_parent"
android:layout_height="match_parent"
android:orientation="vertical">
<TextView
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:gravity="center"
android:text="Title"
android:textSize="21sp"/>
<android.support.v7.widget.RecyclerView
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:paddingBottom="30dp">
</android.support.v7.widget.RecyclerView>
</LinearLayout>
<Button
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:layout_gravity="bottom"
android:text="Submit"/>
</FrameLayout>
The Title and RecyclerView will wrap content according to contents and button will always take up bottom place.
I suggest using RelativeLayout as it handles the positioning of views for cases like yours, so that you can actually focus on main design.
<?xml version="1.0" encoding="utf-8"?>
<RelativeLayout 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">
<TextView
android:id="#+id/title"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:layout_alignParentTop="true"
android:text="Some title" />
<android.support.v7.widget.RecyclerView
android:id="#+id/recyclerView"
android:layout_width="match_parent"
android:layout_height="match_parent"
android:layout_below="#+id/title"
android:layout_above="#+id/button"/>
<Button
android:id="#+id/button"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:layout_alignParentBottom="true"
android:layout_centerHorizontal="true"
android:gravity="center"/>
</RelativeLayout>
Above XML code is the skeleton code for what you need. you can add margins and dimensions to control the spacing. But in any case (until you provide negative margins) your views will never overlap each other.
Main trick of using RelativeLayout is the ability to use XML tags like
android:layout_below or android:layout_above or android:layout_start
or android:layout_end which perfectly aligns your view the way you
want.
Hi guys while I was designing an app, I got to wonder why in ScrollView you cannot go layout_centerHorizontal = "true" in android. So below is my simple code I wrote for this purpose. The first button does not feature layout_centerHorizontal = "true" although I wrote it there manually, it doesn't align in the center.
However, the second button which is outside ScrollView it aligns perfectly in the middle of the width of the parent.
Why is this?
<RelativeLayout
xmlns:android="http://schemas.android.com/apk/res/android"
android:layout_width="match_parent"
android:layout_height="match_parent">
<ScrollView
android:layout_width="match_parent"
android:layout_height="match_parent">
<Button
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:layout_centerHorizontal="true"/>
</ScrollView>
<Button
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:layout_centerHorizontal="true"/>
</RelativeLayout>
Please try this -
<ScrollView
android:layout_width="match_parent"
android:gravity="center_horizontal"
android:layout_height="match_parent">
<Button
android:layout_width="wrap_content"
android:layout_height="wrap_content"/>
</ScrollView>
A ScrollView is a FrameLayout, meaning you should place one child in it containing the entire contents to scroll; this child may itself be a layout manager with a complex hierarchy of objects.
Moreover, as a child of ScrollView means of FrameLayout, you cannot use
android:layout_centerHorizontal="true"
If you want to make button in center please use
android:layout_gravity="center_horizontal"
Recently picking up android development, I have hit a snag in the road. I'm having trouble positioning my layouts. Screenshots are as follows:
I'm trying to input either another layout type/list view in the upper section of the screen, without disrupting the button/text box at the bottom, though.. When extending this layout. I hit the following snag:
The entire contents of the original frame shift when the box of the new layout is extended, I've tried modifying:
android:layout_gravity="top">
and other layout attributes such as weight, margin, height/width.. This always hits the same problem.
My XML for this view is:
<LinearLayout 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"
android:orientation="horizontal" >
<FrameLayout
android:layout_width="wrap_content"
android:layout_height="483dp"
android:layout_weight="1.06"
android:layout_gravity="top">
</FrameLayout>
<EditText android:id="#+id/edit_message"
android:layout_width="0dp"
android:layout_height="wrap_content"
android:layout_weight="1"
android:hint="#string/edit_message"
android:layout_gravity="bottom" />
<Button
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:text="#string/button_send"
android:layout_gravity="bottom"
android:onClick="SendMessageButton"
/>
</LinearLayout>
Though, i'm some-what stuck on how to make the correct changes & any response to this question would be greatly appreciated!
At the moment, all your child views live inside a single horizontally-oriented LinearLayout. LinearLayouts always arrange views sequentially, as you are experiencing.
There are a couple different ways to achieve the layout you are looking for. I'm going to suggest one that uses nested LinearLayouts (an outer one to stack things vertically, and then a nested one to arrange the EditText and Button horizontally), but you could also consider using a RelativeLayout for this.
Updated layout:
<LinearLayout
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"
android:orientation="vertical">
<FrameLayout
android:layout_width="match_parent"
android:layout_height="0dp"
android:layout_weight="1" />
<LinearLayout
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:orientation="horizontal">
<EditText
android:id="#+id/edit_message"
android:layout_width="0dp"
android:layout_height="wrap_content"
android:layout_weight="1"
android:hint="#string/edit_message" />
<Button
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:text="#string/button_send"
android:onClick="SendMessageButton" />
</LinearLayout>
</LinearLayout>
Note that a LinearLayout is oriented horizontally by default; I have explicitly included the attribute here to make the structure more clear.
The reason, your button and editText is appearing far from the frame layout and not near the corner is the parent layout orientation is Horizontal.
Change it to Vertical.
Now, if you need your button and editText to be arranged in the same line, it should be mentioned as described in samgak answer.
However, i would like to suggest the following.
Using framelayout might create bad user experience across different screen sizes in android.
If the parent layout in Linear, if the screen size is x and all your components added if the height it takes is x-20, then the theme you set for parent layout would not cover the entire screen. Therefore, it is recommended to use RelativeLayout and for the button and editText, use the layout_alignParentBottom = true attribute.
If needed, i can share the code sample for this. Added Vertical Scroll to the 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:layout_width="match_parent"
android:layout_height="match_parent"
android:orientation="vertical" >
<FrameLayout
android:layout_width="fill_parent"
android:layout_height="483dp"
android:layout_gravity="top">
</FrameLayout>
<LinearLayout
android:orientation="horizontal"
android:layout_width="fill_parent"
android:layout_height="wrap_content">
<EditText android:id="#+id/edit_message"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:hint="Edit Message"
android:layout_gravity="bottom" />
<Button
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:text="Send"
android:layout_gravity="bottom"
android:onClick="SendMessageButton"
/>
</LinearLayout>
</LinearLayout>
</ScrollView>
I use this tut http://www.androidhive.info/2013/07/android-expandable-list-view-tutorial/ for know how to use expanablelistview in android but i have a problem, many childviews of my form take a long text then it auto down to 2nd row. I want only single row, so i add a HorizontalScrollView to list_item.xml like this:
<HorizontalScrollView
android:layout_width="match_parent"
android:layout_height="wrap_content">
<TextView
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:id="#+id/lblListItem"
android:textSize="17dp"/>
</HorizontalScrollView>
It work but each child get a scroll,..aww (i know it'll happen but got no idea)
Some solution for this issue?
Thanks
It is not cleared If u don't want to show scrollbar then try this
<HorizontalScrollView
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:scrollbars="none">
<TextView
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:id="#+id/lblListItem"
android:singleLine="true"
android:textSize="17dp"/>
</HorizontalScrollView>
