Here is my layout:
<RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android"
xmlns:tools="http://schemas.android.com/tools"
android:id="#+id/outerBox"
android:layout_width="wrap_content"
android:layout_height="fill_parent" >
<GridLayout
android:id="#+id/checksHere"
android:layout_width="fill_parent"
android:layout_height="wrap_content"
android:columnCount="5"
android:columnWidth="100dp" />
<GridLayout
android:id="#+id/textHere"
android:layout_width="fill_parent"
android:layout_height="wrap_content"
android:layout_below="#id/checksHere"
android:columnCount="4" />
<Button
android:id="#+id/submitButton"
android:layout_width="185dip"
android:layout_height="wrap_content"
android:layout_alignLeft="#id/outerBox"
android:layout_below="#id/textHere"
android:layout_margin="3dip"
android:onClick="submit"
android:text="#string/submit" />
<Button
android:id="#+id/cancelButton"
android:layout_width="185dip"
android:layout_height="wrap_content"
android:layout_below="#id/textHere"
android:layout_margin="3dip"
android:layout_toRightOf="#id/submitButton"
android:onClick="next"
android:text="#string/cancel" />
<Button
android:id="#+id/backButton"
android:layout_width="185dip"
android:layout_height="wrap_content"
android:layout_below="#id/textHere"
android:layout_margin="3dip"
android:layout_toRightOf="#id/cancelButton"
android:onClick="next"
android:text="test" />
</RelativeLayout>
I have a relative layout. The layout has two grid layouts at the top, which can be populated in my java code with text or checks. They can be blank. Then I have three buttons. The first two buttons display on the screen just fine. The third button just sits on top of the first button:
I changed the third button (backButton) to be toRightOf submitButton just to see what would happen. It goes on top of the cancelButton, as expected. I feel like I'm missing a simple fundamental, but I have not been able to figure it out.
Well this doesn't necessarily fix the problem with RelativeLayout, but you could always group the three buttons together in a single LinearLayout. This should prevent the buttons from overlapping.
I am not sure but when testing in eclipse changing all the android:layout_width="185dip" to android:layout_width="wrap_content" for buttons worked for me.

i'm looking for an option to scroll through multiple lists (horizontally) like in the Picture in the attachment. You have the possibility to swipe left or Right to get to the next listview. On top there should be some buttons to click or to scroll
I tried putting ListViews in something like this Code but it doesn't work properly.
<HorizontalScrollView
android:id="#+id/horizontalScroll"
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:scrollbarFadeDuration="250">
<LinearLayout
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:orientation="horizontal"
android:layout_marginBottom="0px">
<Button
android:id="#+id/buttonOne"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:background="#color/Black"
android:text="hallo"
android:textColor="#color/White">
</Button>
<Button
android:id="#+id/buttonTwo"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:background="#color/Black"
android:text="hallo"
android:textColor="#color/White">
</Button>
</LinearLayout>
</HorizontalScrollView>
I got it. The Tool I was looking for is a ViewPager.
i am beginner to android programming and trying to build a simple app program.
whenever i try to make more than one views they stack on each other.
I am trying to make a text field and a button, but when i run it, the text field and button overlap each other however, i want them to be separated by some distance.
i am using the following code.
<RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android"
xmlns:tools="http://schemas.android.com/tools"
xmlns:android1="http://schemas.android.com/apk/res/android"
android:layout_width="match_parent"
android:layout_height="match_parent"
android:orientation="horizontal"
tools:context="com.example.new1.MainActivity" >
<EditText android:id="#+id/edit_message"
android:layout_weight= "1"
android:layout_width="0dp"
android:layout_height="wrap_content"
android:hint="#string/edit_message" />
<Button
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:text="#string/button_send" />
</RelativeLayout>
i am checking this code on Samsung Galaxy S2.
does anybody knows the solution to this problem and can guide me where i am doing it wrong.
Either use LinearLayout so that elements stack horizontally or vertically, or use attributes such as android:layout_toRightOf="#id/edit_message" to control placement within a RelativeLayout.
Find out more about LinearLayout here: http://developer.android.com/guide/topics/ui/layout/linear.html and RelativeLayout here: http://developer.android.com/guide/topics/ui/layout/relative.html
RelativeLayout positions views relative to each other. So if you do not specify the relationship between view, all the views will be put one above the other. You can either use LinearLayout with orientation attribute or define relationship between views. Following can be your working code
<?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="fill_parent" >
<EditText
android:id="#+id/edit_message"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:gravity="center_vertical"
android:hint="#string/edit_message"
/>
<Button
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:layout_toRightOf="#id/edit_message"
android:text="#string/button_send" />
</RelativeLayout>
Here android:layout_toRightOf="#id/edit_message" lets your button to be positioned to right of your edittext
Depending on what you want, a horizontal layout or vertical, you need a fitting layout xml.
You use relativeLayout, where you have to specify the parents to layout like:
android:layout_alignParentTop="true"
android:layout_alignParentLeft="true"
android:layout_alignParentStart="true"
If your beginner better take a look at a linear layout in vertical or horizontal mode.
You dont have to specify this then.
Like this:
<LinearLayout
android:layout_width="fill_parent"
android:layout_height="wrap_content"
android:orientation="horizontal"
android:weightSum="100"
>
<Button
android:layout_width="fill_parent"
android:layout_height="wrap_content"
android:id="#+id/bResults"
android:text="Try Command"
android:layout_weight="20" />
<ToggleButton
android:layout_width="fill_parent"
android:layout_height="wrap_content"
android:id="#+id/tbPassword"
android:layout_weight="80"
android:checked="true"
/>
</LinearLayout>
This will put your two buttons nexto each other
This is a strange issue I'm having with my Samsung GT-I9003L. I've a ScrollView containing a LinearLayout with different stuff inside (ImageView, Button, EditText, etc.) and it works perfectly when tested in the emulator, both in 2.3.3 and 4.2 versions.
<ScrollView xmlns:android="http://schemas.android.com/apk/res/android"
android:id="#+id/scroll_view"
android:layout_width="fill_parent"
android:layout_height="wrap_content" >
<LinearLayout
android:layout_width="fill_parent"
android:layout_height="wrap_content"
android:orientation="vertical"
android:padding="16dp" >
<ImageView
android:id="#+id/image"
android:layout_width="fill_parent"
android:layout_height="200dp"
android:contentDescription="#string/img_description"
android:src="#drawable/ic_launcher" />
<Button
android:id="#+id/btn_camera"
android:layout_width="fill_parent"
android:layout_height="wrap_content"
android:text="#string/add_new_btn_camera" />
<Button
android:id="#+id/btn_gallery"
android:layout_width="fill_parent"
android:layout_height="wrap_content"
android:text="#string/add_new_btn_gallery" />
<EditText
android:id="#+id/name"
android:layout_width="fill_parent"
android:layout_height="wrap_content"
android:ems="10"
android:hint="#string/add_new_name_hint"
android:inputType="text"
android:maxLength="80" />
[...]
</LinearLayout>
</ScrollView>
The thing is that when I test it on my phone, the overscroll indicators (the blue/orange glows) doesn't show at all. I've managed to get them working with this line:
ScrollView addNewScroll = (ScrollView)findViewById(R.id.scroll_view);
addNewScroll.setOverScrollMode(ScrollView.OVER_SCROLL_IF_CONTENT_SCROLLS);
But when I reach the top or the end, the glow just "appears", it doesn't animates or fades in.
Thanks in advance for your help!
We are having the exact same issue. Overscolling doesn't seem to work on Samsung Galaxy 2 (Touchwiz), but also on HTC One X phones (older HTC's seem to work).
Is suspect that they replaced the ScrollView implementation with their own, maybe for the stretchy scrollbars or something.
I want to add two buttons in a single linear layout with horizontal orientation, I want my buttons to be stretched if the screen is bigger and contracted if the screen is small, what should I do to keep those exactly the same size together?
Fill parent or match parent causes only one to be displayed on the screen, what should be done to make both of them visible at the same time on any screen size?
give both of them the following properties :
weight =1
layout_width=fill_parent
here is a working code
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:layout_width="fill_parent"
android:layout_height="wrap_content"
android:orientation="horizontal" >
<Button
android:layout_width="fill_parent"
android:layout_height="wrap_content"
android:layout_weight="1"
android:text="Button 1" >
</Button>
<Button
android:layout_width="fill_parent"
android:layout_height="wrap_content"
android:layout_weight="1"
android:text="Button 2" >
</Button>
</LinearLayout>
I have some problem with multiple screen support, I work with dp(dpi) for specify the layout_heigth and layout_width and I hope that is the better way to support multiple screen, but when I tried with two smartphone I meet two different result.
I give an example, this is a layout I use:
<?xml version="1.0" encoding="UTF-8"?>
<RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:id="#+id/cities_main_layout"
android:orientation="vertical"
android:layout_width="fill_parent"
android:layout_height="fill_parent">
<ListView
android:id="#+id/citieslist"
android:layout_width="wrap_content"
android:layout_height="320dip"
android:layout_gravity="center_vertical"
android:layout_below="#id/cities_main_layout"
/>
<LinearLayout
android:id="#+id/cities_button_layout"
android:orientation="horizontal"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:layout_below="#id/citieslist"
android:layout_gravity="center_vertical">
<Button
android:id="#+id/bycountry"
android:layout_height="50dip"
android:layout_width="105dip"
android:background="#drawable/buttonmarket"
android:text="#string/button_bycountry"
/>
<Button
android:id="#+id/top10"
android:layout_height="50dip"
android:layout_width="105dip"
android:background="#drawable/buttonmarket"
android:text="#string/button_top10"
/>
<Button
android:id="#+id/recommended"
android:layout_height="50dip"
android:layout_width="105dip"
android:background="#drawable/buttonmarket"
android:text="#string/button_recommended"
/>
</LinearLayout>
</RelativeLayout>
The button are at the bottom of the layout, and I see two different result:
http://img600.imageshack.us/img600/5513/htcmagicg2.png http://img600.imageshack.us/img600/5513/htcmagicg2.png
http://img441.imageshack.us/img441/6440/samsunggalaxys.png http://img441.imageshack.us/img441/6440/samsunggalaxys.png
In the last smartphone I can see the buttons, instead in the first I cannot...what's wrong?
I have to write a layout for any set of screen??!!!
Your ListView has
android:layout_height="320dip"
Now if the phone screen is smaller, it will not fit.
Try doing this instead: (Edited due to comments. This is displayed correcty in eclipse)
<?xml version="1.0" encoding="utf-8"?>
<RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:id="#+id/relative"
android:orientation="vertical"
android:layout_width="fill_parent"
android:layout_height="fill_parent">
<ListView
android:id="#+id/listview"
android:layout_width="fill_parent"
android:layout_height="fill_parent"
android:background="#FF0000"
android:layout_above="#+id/linlay">
</ListView>
<LinearLayout
android:id="#+id/linlay"
android:orientation="horizontal"
android:layout_width="fill_parent"
android:layout_height="30dip"
android:background="#00FF00"
android:layout_alignParentBottom="true">
</LinearLayout>
</RelativeLayout>
Thant should fix it I think.
Cheers
As others have indicated, your problem is that you hardwired in a size for the ListView. If you want a business rule of "have the buttons at the bottom and have the ListView fill up the rest", you actually need to write code that implements "have the buttons at the bottom and have the ListView fill up the rest".
There are two main approaches here:
Use a LinearLayout parent for the buttons and the ListView. Use
android:layout_height="0px" and android:layout_weight="1" for the
ListView. Use a regular android:layout_height for the buttons (presumably in their own LinearLayout) and no
android:layout_weight for for them
Use a RelativeLayout parent for the buttons and the ListView.
Define the buttons as having android:layout_alignParentBottom="true".
Define the ListView as having android:layout_alignParentTop="true"
and android:layout_above="...", where the ... is the ID of the buttons' LinearLayout.
I would say it's because you are specifically declaring a height for your ListView and then laying the LinearLayout that holds your buttons at the bottom. Try changing it instead of being at the bottom of the ListView to something like
<LinearLayout
android:id="#+id/cities_button_layout"
android:orientation="horizontal"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:alignparentbottom="true"
android:layout_gravity="center_vertical">
I'm not entirely sure if align_parent_bottom is the 100% correct spelling of that.
Well, others have beaten me to it while I was typing, haha, but yeah, you're hardwiring a lot of things that shouldn't be, both the ListView and the Buttons. Take a look at this:
<?xml version="1.0" encoding="UTF-8"?>
<RelativeLayout
xmlns:android="http://schemas.android.com/apk/res/android"
android:id="#+id/cities_main_layout"
android:layout_width="fill_parent"
android:layout_height="fill_parent"
>
<LinearLayout
android:id="#+id/cities_button_layout"
android:orientation="horizontal"
android:layout_width="fill_parent"
android:layout_height="wrap_content"
android:layout_alignParentBottom="true"
>
<Button
android:id="#+id/bycountry"
android:layout_height="50dip"
android:layout_width="fill_parent"
android:layout_weight="1"
android:background="#drawable/buttonmarket"
android:text="#string/button_bycountry"
/>
<Button
android:id="#+id/top10"
android:layout_height="50dip"
android:layout_width="fill_parent"
android:layout_weight="1"
android:background="#drawable/buttonmarket"
android:text="#string/button_top10"
/>
<Button
android:id="#+id/recommended"
android:layout_height="50dip"
android:layout_width="fill_parent"
android:layout_weight="1"
android:background="#drawable/buttonmarket"
android:text="#string/button_recommended"
/>
</LinearLayout>
<ListView
android:id="#+id/citieslist"
android:layout_width="fill_parent"
android:layout_height="fill_parent"
android:layout_above="#id/cities_button_layout"
/>
</RelativeLayout>
You have android:orientation on your RelativeLayout, which isn't actually an attribute that RelativeLayout contains.
You should use the layout_weight attribute rather than hardwiring sizes for the Buttons. In my example, all buttons have a width of fill_parent, and a weight of 1. This makes them distribute the space evenly.
List the fixed button layout first, setting it to alignParentBottom="true". Then set the ListView to fill_parent, and layout_above your button layout. This keeps the button layout at the bottom, and makes the ListView take all the space above your buttons.
Tada!
