im trying to build a form, with a textview and a datepicker,something like:
|Date: |
|datePickerHere|
the problem is i think i have the "same" code as the developer guide but it isnt working. it always ends up like:
|Date: datePickerHere|
Heres the code:
<?xml version="1.0" encoding="utf-8"?>
<ScrollView xmlns:android="http://schemas.android.com/apk/res/android"
android:id="#+id/scrollView1"
android:layout_width="fill_parent"
android:layout_height="fill_parent" >
<LinearLayout android:layout_width="fill_parent"
android:layout_height="wrap_content">
<TextView android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:textSize="15sp"
android:text="#string/data_label"/>
<DatePicker
android:id="#+id/data"
android:layout_width="fill_parent"
android:layout_height="wrap_content" />
</LinearLayout>
</ScrollView>
Change
<LinearLayout android:layout_width="fill_parent"
android:layout_height="wrap_content">
to
<LinearLayout android:layout_width="fill_parent"
android:layout_height="wrap_content"
android:orientation="vertical">
Linear Layouts will default to horizontal orientation if you don't specify the "android:orientation" tag. You must specify it as vertical to achieve what you want

I am trying to make a layout where there are a LinearLayout and inside it I want a FrameLayout and a button.
I want the button to use the bottom of the linearlayout and to use the maximum width and the enough height for the button, using wrap content.
The other component, the FrameLayout I want to use it the remaining part of the screen.
How can I do it?
Here it the layout so far..
<?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="match_parent"
android:orientation="vertical" >
<FrameLayout
android:id="#+id/camera_preview"
android:layout_width="fill_parent"
android:layout_height="fill_parent" />
<Button
android:id="#+id/button_capture"
android:layout_width="fill_parent"
android:layout_height="fill_parent"
android:onClick="snapIt"
android:text="#string/Capture" />
</LinearLayout>
Is not showing the button :s
Thanks alot in advance ;)
Better to work out with relative layout with button aligned to parent bottom and your frame layout above it occupying the rest space of the screen.Like this
<?xml version="1.0" encoding="utf-8"?>
<RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:layout_width="wrap_content"
android:layout_height="match_parent" >
<FrameLayout
android:id="#+id/camera_preview"
android:layout_width="fill_parent"
android:layout_height="fill_parent"
android:layout_above="#+id/button_capture"/>
<Button
android:id="#+id/button_capture"
android:layout_width="fill_parent"
android:layout_height="wrap_content"
android:onClick="snapIt"
android:layout_alignParentBottom="true"/>
</RelativeLayout>
use the following xml
<?xml version="1.0" encoding="utf-8"?>
<RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:layout_width="wrap_content"
android:layout_height="match_parent"
android:orientation="vertical" >
<Button
android:id="#+id/button_capture"
android:layout_width="fill_parent"
android:layout_height="wrap_content"
android:onClick="snapIt"
android:layout_alignParentBottom="true"
android:text="capture" />
<FrameLayout
android:id="#+id/camera_preview"
android:layout_width="fill_parent"
android:layout_height="match_parent"
android:layout_above="#+id/button_capture"
/>
</RelativeLayout>
i am just trying to make these layout, after compare my layout code and your layout code, i find a different code, there is in my code. Did you missing it or just move it away cause it useless from the layout code ?
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:layout_width="fill_parent"
android:layout_height="fill_parent"
android:orientation="vertical" >
<Button
android:id="#+id/button1"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:text="Button" />
<FrameLayout
android:id="#id/flayout"
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:text="#string/hello_world">
</FrameLayout>
</LinearLayout>
I have two edittext views. One of them has only one line, its the title. But the other one should fill the linearlayout to the end, but it doesn't.
I updated the code so this is my whole xml for this app. I hope someone can find what's wrong. The part that i want to form like this is the part inside the LinearLayout named addView.
<?xml version="1.0" encoding="utf-8"?>
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:id="#+id/mainLayout"
android:layout_width="fill_parent"
android:layout_height="fill_parent"
android:orientation="vertical"
android:background="#ffffff">
<LinearLayout
xmlns:android="http://schemas.android.com/apk/res/android"
android:orientation="horizontal"
android:layout_width="fill_parent"
android:layout_height="wrap_content"
>
<Button
android:id="#+id/addButton"
android:layout_height="wrap_content"
android:layout_width="wrap_content"
android:background="#drawable/addbuttonstyle"
android:layout_weight="20"/>
<ImageView
android:id="#+id/titleView"
android:layout_height="wrap_content"
android:layout_width="wrap_content"
android:background="#drawable/titleview"
android:layout_weight="60"/>
<Button
android:id="#+id/orderButton"
android:layout_height="wrap_content"
android:layout_width="wrap_content"
android:background="#drawable/orderbuttonstyle"
android:layout_weight="20"/>
</LinearLayout>
<FrameLayout
xmlns:android="http://schemas.android.com/apk/res/android"
android:layout_width="fill_parent"
android:layout_height="wrap_content"
>
<LinearLayout
xmlns:android="http://schemas.android.com/apk/res/android"
android:id="#+id/addView"
android:orientation="vertical"
android:layout_width="fill_parent"
android:layout_height="fill_parent"
>
<EditText
android:id="#+id/textBoxTitle"
android:layout_width="fill_parent"
android:layout_height="wrap_content"
android:hint="note title"
android:singleLine="true"
/>
<EditText
android:id="#+id/textBoxContent"
android:layout_width="fill_parent"
android:layout_height="fill_parent"
android:hint="content"
/>
</LinearLayout>
<LinearLayout
xmlns:android="http://schemas.android.com/apk/res/android"
android:id="#+id/backgroundLayout"
android:orientation="horizontal"
android:layout_width="fill_parent"
android:layout_height="wrap_content"
android:background="#drawable/background"
/>
</FrameLayout>
I changed textBoxTitle's height to wrap_content and I see this:
Is this what you were hoping for? Also if you want content to appear in the upper-left corner use this attribute:
<EditText
...
android:gravity="top"
/>
So i found what was wrong.
I needed to set layout_height (of the textBoxContent view) to 0dp and layout_weight (of the textBoxContent view) to 1.
The first view should have android:layout_width="wrap_content"
I can't understand why the following code places my TextView in the top left corner of my screen. Based on my understanding of layout_gravity, it seems that it should place my TextView at the bottom of my screen instead.
Can anyone please shed some light on this for me? This Linear Layout, despite seeming very simplistic, has caused me numerous headaches. How can something that seems so simple, be such a royal pain to grasp?
<?xml version="1.0" encoding="utf-8"?>
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:layout_width="fill_parent"
android:layout_height="fill_parent"
android:orientation="vertical"
android:background="#FF0000">
<TextView
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:text="#string/hello"
android:layout_gravity="bottom"
android:background="#FFF"
/>
</LinearLayout>
A LinearLayout set to vertical orientation will ignore all layout_gravity parameters that refers to vertical alignment. So for example "bottom" wont work but "center-horizontal" will work. (The vertical alignment is always done so that each view in the layout i placed under the other views in the layout.)
A relative layout might be the way to go or maybe you can use this code that probably is pretty close to what you want.
<?xml version="1.0" encoding="utf-8"?>
<LinearLayout
xmlns:android="http://schemas.android.com/apk/res/android"
android:layout_width="fill_parent"
android:layout_height="fill_parent"
android:orientation="vertical"
android:background="#FF0000"
>
<TextView
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:text="#string/hello"
android:gravity="bottom"
android:layout_weight="1.0"
android:background="#FFF" />
</LinearLayout>
Edit This blog explains things further.
<?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"
android:background="#FF0000">
<TextView
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:text="#string/hello"
android:layout_alignParentBottom="true"
android:background="#FFF"
/>
</RelativeLayout>
you can use relative layout were you can align bottom easily
If that is the simplicity of your layout, you shouldn't wrap it in a LinearLayout at all.
<?xml version="1.0" encoding="utf-8"?>
<TextView xmlns:android="http://schemas.android.com/apk/res/android"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:layout_gravity="bottom"
android:background="#FFF"
android:text="HELLO HELLO" />
If you need to wrap it though, remove the vertical orientation:
<?xml version="1.0" encoding="utf-8"?>
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:layout_width="fill_parent"
android:layout_height="fill_parent"
android:background="#FF0000" >
<TextView
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:layout_gravity="bottom"
android:background="#FFF"
android:text="HELLO HELLO" />
</LinearLayout>
I think this code do what you want:
<?xml version="1.0" encoding="utf-8"?>
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:layout_width="fill_parent"
android:layout_height="fill_parent"
android:orientation="vertical"
android:gravity="bottom"
android:background="#FF0000">
<TextView
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:text="#string/hello"
android:background="#FFF"
/>
</LinearLayout>
And if you want the textview on center, you can use:
<?xml version="1.0" encoding="utf-8"?>
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:layout_width="fill_parent"
android:layout_height="fill_parent"
android:orientation="vertical"
android:gravity="bottom"
android:background="#FF0000">
<TextView
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:text="#string/hello"
android:layout_gravity="center"
android:background="#FFF"
/>
</LinearLayout>
Hope this help you.
My layout was perfect until I decided to add a scrollview.
<?xml version="1.0" encoding="utf-8"?>
<TableLayout android:id="#+id/tableLayout1" android:layout_width="fill_parent" android:layout_height="fill_parent" xmlns:android="http://schemas.android.com/apk/res/android">
<ScrollView android:id="#+id/scrollView1" android:layout_width="wrap_content" android:layout_height="wrap_content" android:layout_weight="1" >
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android" android:layout_width="fill_parent" android:layout_height="fill_parent" android:orientation="vertical" android:id="#+id/linearLayout1">
<TableLayout android:layout_width="match_parent" android:layout_height="wrap_content" android:id="#+id/tableLayout1"/>
</LinearLayout>
</ScrollView>
<Button android:layout_width="match_parent" android:id="#+id/button1" android:text="Start" android:layout_height="50dip" android:onClick="getOutput"></Button>
</TableLayout>
I would like the button to stay at the bottom of the screen, I would actually like the scrollview to take up the entire screen. With just the inner table layout it works fine. In the Graphical Layout preview it looks how I want it, but not when I run it.
I would like the scrollview to take up the whole screen except the button, which I'd like to be at the bottom.
you could use RelativeLayout or LinearLayout as Root view. Giving Button more weight. That way ScrollView won't take up the whole thing.
this should work
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:layout_width="fill_parent" android:layout_height="fill_parent"
android:orientation="vertical">
<ScrollView android:layout_width="fill_parent" android:layout_height="0dip"
android:layout_weight="1.0">
<LinearLayout android:layout_width="fill_parent"
android:layout_height="fill_parent" android:orientation="vertical"
android:id="#+id/linearLayout1">
<TableLayout android:layout_width="fill_parent"
android:layout_height="fill_parent"
android:id="#+id/tableLayout1"/>
</LinearLayout>
</ScrollView>
<Button android:layout_width="fill_parent" android:layout_height="wrap_content"
android:text="Bottom Button"/>
</LinearLayout>
Try setting ScrollView fillViewport attribute to true.
I am using this XML to show my one Button at the bottom and one TextView at the top with one TextView right in the middle. The middle textview covers the whole span in between the button and the top textview. The middle TextView is not being displayed at all. What is wrong?
<?xml version="1.0" encoding="utf-8"?>
<RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:orientation="vertical"
android:layout_width="fill_parent"
android:layout_height="fill_parent">
<TextView
android:id="#+id/task"
android:layout_width="fill_parent"
android:layout_height="wrap_content"
android:text="#string/tasks"
/>
<Button
android:id="#+id/btnAddTask"
android:layout_width="fill_parent"
android:layout_height="wrap_content"
android:text="#string/AddTasks"
android:layout_alignParentBottom="true"
/>
<TextView
android:id="#+id/TasksList"
android:layout_width="fill_parent"
android:layout_height="wrap_content"
android:text="#string/tasks"
android:layout_above="#id/task"
android:layout_below="#id/btnAddTask"
/>
</RelativeLayout>
Your problem is definitely that you have the TasksList TextView below your button. Swap your layout_above and layout_below values. This works for me:
<?xml version="1.0" encoding="utf-8"?>
<RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:orientation="vertical"
android:layout_width="fill_parent"
android:layout_height="fill_parent">
<TextView
android:id="#+id/task"
android:layout_width="fill_parent"
android:layout_height="wrap_content"
android:text="#string/tasks"
/>
<Button
android:id="#+id/btnAddTask"
android:layout_width="fill_parent"
android:layout_height="wrap_content"
android:text="#string/AddTasks"
android:layout_alignParentBottom="true"
/>
<TextView
android:id="#+id/TasksList"
android:layout_width="fill_parent"
android:layout_height="wrap_content"
android:text="#string/tasks"
android:layout_above="#id/btnAddTask"
android:layout_below="#id/task"
/>
</RelativeLayout>
The problem wsa that you reversed your layout above and the layout below:
try
android:layout_below="#id/task"
android:layout_above="#id/btnAddTask"
See screenshot.
And here is the complete layout.
<?xml version="1.0" encoding="utf-8"?>
<RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:orientation="vertical"
android:layout_width="fill_parent"
android:layout_height="fill_parent">
<TextView
android:id="#+id/task"
android:layout_width="fill_parent"
android:layout_height="wrap_content"
android:text="#string/tasks"
/>
<Button
android:id="#+id/btnAddTask"
android:layout_width="fill_parent"
android:layout_height="wrap_content"
android:text="#string/AddTasks"
android:layout_alignParentBottom="true"
/>
<TextView
android:id="#+id/TasksList"
android:layout_width="fill_parent"
android:layout_height="wrap_content"
android:text="#string/tasks"
android:layout_below="#id/task"
android:layout_above="#id/btnAddTask"
/>
</RelativeLayout>
There's definitely something wrong with how you have this laid out.
You have for the button, alignParentBottom="true"... then for the TasksList TextView it is set to be below the button... basically off the screen.
You can remove orientation from the RelativeLayout... Relative layout's do not have orientation like LinearLayout's do.
As you're describing... I'm not 100% you can do it with a Relative Layout. If you simply wanted one thing on top, one centered and the other on bottom, it would be best to use a single layout parameter for each one, centerInParent, alignParentTop and alignParentBottom.
If you reconsider LinearLayout (as I'm guessing you started with) you'd stick with a Vertical Orientation, then give them layout_weight of 0, 1, and 0 making sure the height was set to wrap_content.
