Auto-shrink TextView according to screensize - android

I'm trying to get TextView to wrap according to the device screensize so that the 3 button at the bottom will always be visible at the bottom of screen.
The layout I'm trying to get
I've tried the solution from here but the ScrollView doesn't seem to work. The 3 buttons is not visible.
The bad layout I'm getting :(
Here are my code. Thanks for reading.
<?xml version="1.0" encoding="utf-8"?>
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:orientation="vertical"
android:layout_width="fill_parent"
android:layout_height="fill_parent">

android:layout_height="wrap_content"
android:scrollbars="vertical"
android:fillViewport="true">

</LinearLayout>

this is what you need , just copy and paste
<RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:orientation="vertical"
android:layout_width="fill_parent"
android:layout_height="wrap_content">
<ScrollView
android:id="#+id/scroll_view"
android:layout_width="fill_parent"
android:layout_height="wrap_content"

android:layout_weight=".8">
<TextView
android:text="#string/temp_txt"
android:textColor="#android:color/black"
android:background="#android:color/white"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:textSize="30dp"
/>
</ScrollView>

android:layout_height="wrap_content"
android:layout_weight="1"
android:textSize="20dp"
android:text="Button 3"/>
</LinearLayout>
</RelativeLayout>

Add android:layout_weight="1" to your ScrollView and change height of ScrollView to 0
Remove android:layout_weight="1" from your TextView
<ScrollView
android:layout_width="fill_parent"
android:layout_height="0dp"
android:scrollbars="vertical"
android:layout_weight="1.0"
android:fillViewport="true">
<TextView
android:text="#string/default_tnc"
android:layout_width="fill_parent"
android:layout_height="fill_parent" // or wrap_content
/>
</ScrollView>
Hope this help

You can RelativeLayout
<?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"
tools:context=".lActivity">
<ScrollView
android:id="#+id/web_view"
android:layout_width="match_parent"
android:layout_height="match_parent">
<TextView
// enter code here
/>
</CrollView>
<RelativeLayout
android:layout_width="match_parent"
android:layout_height="100dp"
android:layout_alignParentBottom="true"
android:background="#FFFFFF">
<Button>
<Button>
<Button>
</RelativeLayout>
</RelativeLayout>

Instead of using a LinearLayout as the main parent, Just use a RelativeLayout. Then just use the layout_above attribute in the ScrollView to have it set to be above the .
ativeLayout 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="wrap_content"
android:layout_above="#+id/id_rl_below"
android:layout_alignParentTop="true"
android:scrollbars="vertical">
<TextView
android:layout_width="match_parent"
android:layout_height="match_parent"
android:layout_weight="1.0"

</ScrollView>
<LinearLayout

android:layout_width="match_parent"
android:layout_height="wrap_content"
android:layout_alignParentBottom="true"
android:orientation="vertical">

</RelativeLayout>

Organizing layouts with edit text at bottom?

I wanted to make a layout with 3 LinearLayouts. In the 2nd LinearLayout I would have a ListView and the 3rd LinearLayout I would have an EditText and Button at the bottom. This was my attempt:
<?xml version="1.0" encoding="utf-8"?>
<RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android"
xmlns:fresco="http://schemas.android.com/apk/res-auto"
android:orientation="vertical"
android:layout_width="match_parent"
android:layout_height="match_parent">
<LinearLayout
android:id="#+id/view_post"
android:layout_width="fill_parent"
android:layout_height="200dp"
android:background="#color/com_facebook_blue">
<TextView
android:layout_width="fill_parent"
android:layout_height="wrap_content"
android:id="#+id/view_status"/>
</LinearLayout>
<LinearLayout
android:id="#+id/view_comments"
android:layout_below="#+id/view_post"
android:layout_width="match_parent"
android:layout_height="250dp">
<ListView
android:id="#+id/lv_comments_feed"
android:layout_width="fill_parent"
android:layout_height="wrap_content">
</ListView>
</LinearLayout>
<LinearLayout
android:layout_below="#+id/view_comments"
android:id="#+id/send_message"
android:layout_width="match_parent"
android:layout_height="50dp"
android:layout_alignParentBottom="true"
android:orientation="horizontal" >
<EditText
android:id="#+id/write_comment"
android:layout_width="0dp"
android:layout_height="wrap_content"
android:layout_gravity="center_vertical|center_horizontal"
android:layout_weight="5"
android:gravity="top|left"
android:inputType="textMultiLine"
android:scrollHorizontally="false" />
<Button
android:id="#+id/send_comment"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:layout_gravity="center_vertical|center_horizontal"
android:gravity="center"
android:text="send"
android:textAppearance="?android:attr/textAppearanceMedium" />
</LinearLayout>
</RelativeLayout>
Now the design looks great but when I load the app on my phone, I have 2 problems:
I don't want to hardcode the LinearLayout heights. I have looked into layout_weight but I can't seem to have these layout_weights work without running into the 2nd problem below:
When I click the EditText, the EditText is hidden even though I have declared android:windowSoftInputMode="adjustResize|stateHidden" in my activity and I'm not sure why that's happening. Also, the EditText and Button are not directly at the bottom of the screen which is what I would want. Any help is appreciated, thanks!
you don't need to add listview as child of linear layout. and avoid fill_parent & use match_parent. if first linear layout is only for textview then don't use it inside of linearlayout. or only use wrap_content instead of a specific layout_height
Here i made some changes hope it will work

How to merge Linear Layout and Table Layout at android?

I'm new android. I have a little bit stack in designing layout for Android. In my scenario, I have two button with Linear Layout. Here my xml.
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:id="#+id/linearLayout2"
android:layout_width="fill_parent"
android:layout_height="fill_parent"
android:orientation="horizontal"
android:background="#color/isp_home_color"
>
<Button
android:layout_width="0dp"
android:layout_height="70dp"
android:layout_weight="1"
android:text="#string/sync_text"
android:background="#color/sync_text_color"
android:id="#+id/btn_syncpin"
android:layout_gravity="left"
android:textStyle="bold"
/>
<Button
android:layout_width="0dp"
android:layout_weight="1"
android:layout_height="70dp"
android:text="#string/topup_text"
android:background="#color/topup_text_color"
android:id="#+id/btn_topup"
android:layout_gravity="right"
android:textStyle="bold"/>
<!--Table Layout will come here -->
</LinearLayout>
Here image for this.
When I add new TableLayout inside Linear Layout. I got this.
Here my xml for Table Layout.
<TableLayout
android:layout_width="fill_parent"
android:layout_height="wrap_content"
android:orientation="vertical" >
</TableLayout>
Actually, I don't want like this. I want two button as shown in first image. Then, next table layout will occur under this two button. Please help me how can I do this layout. Please pointing to me how to make this. Thanks with advanced.
Give orientation as vertical to the LinearLayout not the TableLayout.Put Two buttons in a LinearLayout with orizontal orientation and give orientation "vertical" for the parent LinearLayout
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:id="#+id/linearLayout2"
android:layout_width="fill_parent"
android:layout_height="fill_parent"
android:background="#456789"
android:orientation="vertical" >
<LinearLayout
android:layout_width="fill_parent"
android:layout_height="wrap_content"
android:background="#FFFFFF"
android:orientation="horizontal">
<Button
android:id="#+id/btn_syncpin"
android:layout_width="wrap_content"
android:layout_height="70dp"
android:layout_gravity="left"
android:layout_weight="1"
android:background="#123456"
android:text="tring/"
android:textStyle="bold" />
<Button
android:id="#+id/btn_topup"
android:layout_width="wrap_content"
android:layout_height="70dp"
android:layout_gravity="right"
android:layout_weight="1"
android:background="#978969"
android:text="topup_text"
android:textStyle="bold" />
</LinearLayout>
<TableLayout
android:layout_width="fill_parent"
android:layout_height="wrap_content"
android:background="#FFFFFF" >
</TableLayout>
</LinearLayout>
Check this out, I just checked it on my Machine and it works as desired, although the background preference and the display strings have been removed.
<RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:layout_width="fill_parent"
android:layout_height="fill_parent" >
<LinearLayout
android:id="#+id/linearLayout2"
android:layout_width="fill_parent"
android:layout_height="wrap_content"
android:orientation="horizontal" >
<Button
android:id="#+id/btn_syncpin"
android:layout_width="0dp"
android:layout_height="70dp"
android:layout_gravity="left"
android:layout_weight="1"
android:textStyle="bold" />
<Button
android:id="#+id/btn_topup"
android:layout_width="0dp"
android:layout_height="70dp"
android:layout_gravity="right"
android:layout_weight="1"
android:textStyle="bold" />
</LinearLayout>
<TableLayout
android:layout_width="fill_parent"
android:layout_height="wrap_content"
android:orientation="vertical"
android:layout_below="#+id/linearLayout2">
</TableLayout>
</RelativeLayout>
take Relative Layout as a parent layout.
Following is an example. it will display your buttons and table layout too
<RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:id="#+id/linearLayout1"
android:layout_width="fill_parent"
android:layout_height="fill_parent" >
<LinearLayout
android:id="#+id/linearLayout2"
android:layout_width="fill_parent"
android:layout_height="wrap_content"
android:background="#color/isp_home_color"
android:orientation="horizontal" >
<Button
android:id="#+id/btn_syncpin"
android:layout_width="0dp"
android:layout_height="70dp"
android:layout_gravity="left"
android:layout_weight="1"
android:background="#color/sync_text_color"
android:text="#string/sync_text"
android:textStyle="bold" />
<Button
android:id="#+id/btn_topup"
android:layout_width="0dp"
android:layout_height="70dp"
android:layout_gravity="right"
android:layout_weight="1"
android:background="#color/topup_text_color"
android:text="#string/topup_text"
android:textStyle="bold" />
</LinearLayout>
<TableLayout
android:id="#+id/table"
android:layout_width="fill_parent"
android:layout_height="fill_parent"
android:layout_below="#+id/linearLayout2" >
</TableLayout>
</RelativeLayout>

This answer tells only implementation of button_bar_layout for all android versions with buttons at the bottom/top of an activity which look like AlertDialog with OK/Cancel buttons.

3 layouts - middle is flexible

I need the following thing:
3 layouts:
Header
Content
Footer
Header must be on the top footer must be sticked to the bottom (android:layout_alignParentBottom="true").
But how to make middle to occupy the whole other screen? Thanks.
Here is my solution (with android:layout_weight and ScrollView):
<LinearLayout 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"
android:orientation="vertical" >
<LinearLayout
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:layout_weight="1"
android:background="#DDDDDD"
android:gravity="center"
android:orientation="vertical" >
<TextView
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:text="Header"
tools:ignore="HardcodedText" />
</LinearLayout>
<ScrollView
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:layout_weight="3" >
<TextView
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:layout_gravity="center"
android:text="Content"
tools:ignore="HardcodedText" />
</ScrollView>
<LinearLayout
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:layout_weight="1"
android:background="#DDDDDD"
android:gravity="center"
android:orientation="vertical" >
<TextView
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:text="Footer"
tools:ignore="HardcodedText" />
</LinearLayout></LinearLayout>
And the result picture :
Hi Use the following lines
<?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:orientation="vertical" >
<LinearLayout
android:id="#+id/button1"
android:layout_width="fill_parent"
android:layout_height="wrap_content"
android:layout_alignParentTop="true"
android:text="Button" >
<Button
android:id="#+id/button2"
android:layout_width="fill_parent"
android:layout_height="wrap_content"
android:text="Header" />
</LinearLayout>
<LinearLayout
android:layout_width="fill_parent"
android:layout_height="fill_parent"
android:layout_above="#+id/linearfooter"
android:layout_below="#+id/button1"
android:background="#android:color/darker_gray"
>
</LinearLayout>
<LinearLayout
android:id="#+id/linearfooter"
android:layout_width="fill_parent"
android:layout_height="wrap_content"
android:layout_alignParentBottom="true"
android:text="Button" >
<Button
android:id="#+id/button2"
android:layout_width="fill_parent"
android:layout_height="wrap_content"
android:text="footer" />
</LinearLayout>
</RelativeLayout>
hope this helps you.
Use a height of 0dp and
android:layout_weight
set to 1
Finally I've got the next solution:
To the middle layout I added:
<LinearLayout
android:id="#+id/linearLayout1"
android:layout_width="match_parent"
android:layout_height="match_parent"
android:layout_above="#id/footer"
android:layout_below="#id/header"
android:layout_weight="1">
And it works!

Align two-button layout left and right in Android

I want to align two buttons with a linear layout, one on the left, and one on the right, like the next and previous buttons on an image gallery. I tried to align them but it doesn't work.
XML layout code:
<?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="#android:color/white"
android:gravity="bottom" >
<LinearLayout
android:id="#+id/linearLayout1"
android:layout_width="fill_parent"
android:layout_height="wrap_content"
android:background="#android:color/black" >
<Button
android:id="#+id/button1"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:text="prev"
android:layout_alignParentRight="true" />
<Button
android:id="#+id/button2"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:text="next" />
</LinearLayout>
</LinearLayout>
Actual output:
Expected output:
How can I fix it?
Use a RelativeLayout. There you can set android:layout_alignParentLeft and android:layout_alignParentRight.
This should work for you:
<?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="#android:color/white"
android:gravity="bottom" >
<RelativeLayout
android:id="#+id/relativeLayout1"
android:layout_width="fill_parent"
android:layout_height="wrap_content"
android:background="#android:color/black" >
<Button
android:id="#+id/button1"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:text="prev"
android:layout_alignParentLeft="true" />
<Button
android:id="#+id/button2"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:text="next"
android:layout_alignParentRight="true"/>
</RelativeLayout>
</LinearLayout>
With Linear Layout
<LinearLayout
android:layout_width="match_parent"
android:layout_height="wrap_content">
<LinearLayout
android:layout_width="0dp"
android:layout_height="wrap_content"
android:layout_weight="1">
<Button
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:text="Prev"/>
</LinearLayout>
<Button
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:text="Next"/>
</LinearLayout>
With Relative Layout
<RelativeLayout
android:layout_width="match_parent"
android:layout_height="wrap_content">
<Button
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:text="Prev"
android:layout_alignParentLeft="true"/>
<Button
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:text="Next"
android:layout_alignParentRight="true"/>
</RelativeLayout>
Use Relative layout in your LinearLayout;
Also add android:layout_alignParentLeft="true" to "prev" Button
and android:layout_alignParentRight="true" to "next" Button
<?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="#android:color/white"
android:gravity="bottom"
android:orientation="vertical" >
<RelativeLayout
android:id="#+id/relativeLayout1"
android:layout_width="fill_parent"
android:layout_height="wrap_content"
android:background="#android:color/black" >
<Button
android:id="#+id/button1"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:layout_alignParentLeft="true" <---- ADD this prop
android:text="prev" />
<Button
android:id="#+id/button2"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:layout_alignParentRight="true" <----- ADD this prop
android:text="next" />
</RelativeLayout>
</LinearLayout>
I guess, the simplest solution is to use View in your inner LinearLayout.
<LinearLayout
android:layout_width="match_parent"
android:layout_height="wrap_content">
<Button
android:id="#+id/button1"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:text="prev"/>
<View
android:layout_width="0dp"
android:layout_height="0dp"
android:layout_weight="1"/>
<Button
android:id="#+id/button2"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:text="next"/>
</LinearLayout>
Something like 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"
android:orientation="vertical" >
<RelativeLayout
android:layout_width="wrap_content"
android:layout_height="match_parent"
android:gravity="right" >
<Button
android:id="#+id/button1"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:layout_alignParentRight="true"
android:text="Button" />
<LinearLayout
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:layout_toLeftOf="#+id/button1"
android:orientation="vertical" >
<Button
android:id="#+id/button2"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:text="Button" />
</LinearLayout>
</RelativeLayout>
</LinearLayout>
The idea is, to create a RelativeLayout as container and put first Button and then stick it to the right of parent view. After that, add Another button inside LinearLayout and set this LinearLayout into the left of first Button.
Here's the result.
ur layout xml should be as shown below
<?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:gravity="bottom"
android:background="#fff">
<RelativeLayout
android:id="#+id/relativeLayout1"
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:background="#000"
android:layout_gravity="bottom" >
<Button
android:id="#+id/button1"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:layout_alignParentLeft="true"
android:text="Pre" />
<Button
android:id="#+id/button2"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:layout_alignParentRight="true"
android:text="Next" />
</RelativeLayout>
</RelativeLayout>
Use a RelativeLayout instead of a LinearLayout you can add the tags android:layout_alignParentRight="true" and android:layout_alignParentLeft="true" on each button.
You can use RelativeLayout like this:
<?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="#android:color/white"
android:orientation="vertical" >
<RelativeLayout
android:layout_width="fill_parent"
android:layout_height="wrap_content"
android:background="#android:color/black"
android:gravity="bottom"
android:orientation="horizontal" >
<Button
android:id="#+id/button1"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:layout_alignParentLeft="true"
android:text="prev" />
<Button
android:id="#+id/button2"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:layout_alignParentRight="true"
android:text="next" />
</RelativeLayout>
</LinearLayout>
(I used grey instead of white for the screenshot)
Use a FrameLayout and add the layout_gravity attribute in each of the buttons
Do something like this it will surely help you out
<?xml version="1.0" encoding="utf-8"?>
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:orientation="vertical"
android:layout_width="match_parent"
android:layout_height="match_parent"
>
<TextView android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:text="#string/Linear"
android:textSize="35dp"
android:layout_margin="90dp"
/>
<LinearLayout
android:id="#+id/linearLayout1"
android:layout_width="fill_parent"
android:layout_height="wrap_content"
android:background="#android:color/black">
<Button
android:id="#+id/button1"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:text="Relative"
/>
<Button
android:id="#+id/button2"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:layout_marginStart="200dp"
android:text="Constraint" />
</LinearLayout>
</LinearLayout>
Use margin_Start and End to seprate the buttons in the layout
<?xml version="1.0" encoding="utf-8"?>
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
xmlns:tools="http://schemas.android.com/tools" android:orientation="vertical"
android:layout_width="match_parent"
android:layout_height="wrap_content"
>
<TextView android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:text="-:Linear Layout:-"
android:textSize="35sp"
android:layout_gravity="center"
android:layout_marginTop="250dp"
tools:ignore="HardcodedText"/>
<LinearLayout
android:id="#+id/linear2"
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:orientation="horizontal"
android:layout_marginTop="90dp">
<Button
android:id="#+id/button1"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:text="Relative"
tools:ignore="ButtonStyle,HardcodedText"/>
<Button
android:id="#+id/button2"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:layout_marginStart="200dp"
android:text="Constraint"
tools:ignore="ButtonStyle"
/>
</LinearLayout>
</LinearLayout>

For Better Performance:
Best to put two views left and right and one view between in linear layout rather than relative layout. Use the below code it will also remove the nesting of views .... It will be good in performance perpective :
<?xml version="1.0" encoding="utf-8"?>
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:id="#+id/linearLayout1"
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:gravity="center_vertical">
<Button
android:id="#+id/button1"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:layout_alignParentRight="true"
android:text="prev" />
<TextView android:text="Hi its working"
android:layout_width="0dp"
android:layout_height="wrap_content"
android:layout_weight="1" />
<Button
android:id="#+id/button2"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:text="next" />
</LinearLayout>

android layout: how to write this one?

I want an activity with below layout:
top button
middle(scroll view)
bottom button
I want the bottom button to attach to the bottom of the activity view, and the middle part occupies the rest of the space.
How I can write the layout xml file?
Below doesn't work:
<?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">
<LinearLayout android:focusable="true"
android:focusableInTouchMode="true" android:layout_width="0px"
android:layout_height="0px" />
<LinearLayout android:orientation="vertical"
android:layout_width="fill_parent" android:weightSum="1" android:layout_height="wrap_content">
<LinearLayout android:orientation="horizontal"
android:layout_width="fill_parent" android:layout_height="wrap_content"
android:weightSum="1">
<EditText android:id="#+id/edit_search"
android:layout_width="wrap_content" android:layout_height="wrap_content"
android:lines="1" android:hint="发微博内容" android:layout_weight="0.9" />
<Button android:layout_height="wrap_content" android:text="Search"
android:layout_width="wrap_content" android:id="#+id/search_btn"
android:layout_weight="0.1"></Button>
</LinearLayout>
<TextView android:layout_width="fill_parent"
android:layout_height="wrap_content" android:id="#+id/TextView01"
android:paddingTop="5dip" />
<ListView android:layout_width="fill_parent"
android:id="#+id/lv01" android:layout_height="390dp">
</ListView>
<Button android:id="#+id/create_new_btn"
android:layout_height="wrap_content" android:text="我要评论" android:layout_gravity="bottom"
android:layout_width="fill_parent"></Button>
</LinearLayout>
</LinearLayout>
For that case, just take a RelativeLayout, its better for this case and you don't need to take any sub-layout.
Just try this once and post your XML layout here for the further improvement.
From your xml layout code, i can assume, you just want to have:
EditText+Button=>Top,
TextView+ListView=>Middle,
Create New button=>Bottom,
is this the case?
Keep it simple, go with LinearLayout, and play with the weights:
<LinearLayout
android:orientation="vertical"
android:layout_width="match_parent"
android:layout_height="match_parent">
<Button
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:layout_weight="0">
</Button>
<ScrollView
android:layout_width="match_parent"
android:layout_height="match_parent"
android:layout_weight="1">
<!-- Stuff in scroll view -->
</ScrollView>
<Button
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:layout_weight="0">
</Button>
</LinearLayout>
#ParashMayani is right..
Here is the implementation :
<LinearLayout android:focusable="true"
android:focusableInTouchMode="true" android:layout_width="fill_parent"
android:layout_height="wrap_content" android:id="#+id/relLayout" android:orientation="horizontal" >
<EditText android:id="#+id/edit_search"
android:layout_width="wrap_content" android:layout_height="wrap_content"
android:lines="1" android:hint="Hello" android:layout_weight="0.7"/>
<Button android:layout_height="wrap_content" android:text="Search"
android:layout_weight="0.3" android:layout_width="wrap_content" android:id="#+id/search_btn" />
</LinearLayout>
<TextView android:layout_width="fill_parent"
android:layout_height="wrap_content" android:id="#+id/TextView01"
android:paddingTop="5dip" android:layout_below="#id/relLayout"/>
<Button android:id="#+id/create_new_btn"
android:layout_height="wrap_content" android:text="我要评论" android:layout_gravity="bottom"
android:layout_width="fill_parent" android:layout_alignParentBottom="true"/>
<ListView android:layout_width="fill_parent"
android:id="#+id/lv01" android:layout_height="0dp" android:layout_above="#id/create_new_btn" android:layout_below="#id/TextView01" />
<?xml version="1.0" encoding="utf-8"?>
<RelativeLayout
xmlns:android="http://schemas.android.com/apk/res/android"
android:orientation="vertical"
android:layout_width="match_parent"
android:layout_height="match_parent">
<Button android:id="#+id/button1" android:layout_height="wrap_content" android:layout_width="wrap_content" android:text="Button" android:layout_alignParentTop="true" android:layout_alignParentLeft="true"></Button>
<Button android:id="#+id/button2" android:layout_height="wrap_content" android:layout_width="wrap_content" android:text="Button" android:layout_alignParentBottom="true" android:layout_alignParentLeft="true"></Button>
<ScrollView android:id="#+id/scrollView1" android:layout_height="wrap_content" android:layout_width="match_parent" android:layout_below="#+id/button1" android:layout_above="#+id/button2">
<LinearLayout android:id="#+id/linearLayout1" android:layout_width="match_parent" android:layout_height="match_parent"></LinearLayout>
</ScrollView>
</RelativeLayout>
I think something like that would work. The important part in that layout is the android:layout_below and android:layout_above. You can replace the ScrollView with other layouts such as ListView and it will remain below the first button and above the second regardless of how big it gets. Likewise, the buttons have the attributes android:layout_alignParentTop="true" and android:layout_alignParentBottom="true" which will keep them to the top and the bottom of the RelativeView respectively.
