<RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:layout_width="match_parent"
android:layout_height="match_parent"
>

android:layout_weight="3"
android:text="Send" />
</LinearLayout>
</RelativeLayout>
How to do this as am new for android development someone please help me!
You should change the android:height in layout that u use in your RecyclerViewAdapter to wrap_content
And also in your manifest
<activity
...
android:windowSoftInputMode="adjustPan"
...
></activity>
Their are many libraries out there.This library is a sample Android App which can be used as a starter application for a chat application.You can take reference or implemented this library in your project
check your row item(layout xml file) which is used in your viewholder. I think you have used match_parent in your parent view. Make it as wrap_content.
For that scrolling issue, check your code for smoothScrollToPosition(int). may be you have used this method in your code.

I don't understand this issue. I'm pretty sure I used to do this, yet in this case, the zindex ordering is not followed, and the TextView below is hidden behind the button:
<?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="wrap_content">
<Button
android:text="Button"
android:layout_width="match_parent"
android:layout_height="50dp" />
<TextView
android:textColor="#color/black"
android:text="TextView"
android:layout_width="wrap_content"
android:layout_height="wrap_content" />
</RelativeLayout>
I have restarted Android Studio, but even worse, this is the same on my device too, so its not an Android Studio bug. What is the issue here exactly?
Please use the elevation
android:elevation="10dp"
here is you can see your solution
If you add any views to Relative Layout, It places your view above another view if you don't use layout alignment like layout_above/layout_below/layout_leftof or rightof etc
I am trying to make a layout simulating a Dialog.
I am inserting a ListFragment in my fragment container in this layout. I'm trying to accomplish two things:
Buttons always visible on the bottom of the layout
The layout does not take up the entire height of the screen.
But nothing I try seems to work.
<?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="400dp"
>
<FrameLayout
android:id="#+id/dialog_fragment_container"
android:orientation="vertical"
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:layout_above="#+id/dialog_button_container"/>
<LinearLayout
android:id="#+id/dialog_button_container"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:layout_alignParentBottom="true"
android:orientation="horizontal">
<Button
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:text="New Button"
android:id="#+id/button2"/>
<Button
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:text="New Button"
android:id="#+id/button3"/>
</LinearLayout>
</RelativeLayout>
It always wants to take up the entire height of my screen no matter what I do.
I dont exactly understand what you really want to do but I think the first thing to check out is PopupWindow. It pops up like a normal Dialog but you can completly customize its layout and of course the buttons too. You said you want to
"synthesize" it. Im sure it is not that hard to find the right dimens, fontsize and so on for the buttons. Mostly its all set to the default.
If you want your activity's layout to be look like dialog you can use following lines in your manifest file:
<activity
android:name="Your activity name"
android:theme="#android:style/Theme.Dialog" />
I need to set visible all these three items
1. ActionBar
2. ListView
3. EditText (at Bottom)
When i click on EditText, it pushed the background image and squeezed it. i saw some tutorials and used android:windowSoftInputMode="adjustPan" that solved the squeezing issue but created a new one. When the SoftKeyboard appears, it also hides the ActionBar. I have visited many questions , but none of them was actually helpfull. IS there any way to set ActionBar always visible whatever happening on screen etc...
EDITED
The xml of fragment used to display the ListView and EditText is :
<?xml version="1.0" encoding="utf-8"?>
<RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:id="#+id/RelativeLayout1"
android:layout_width="match_parent"
android:layout_height="match_parent" >
<ListView
android:id="#id/android:list"
style="#style/ContactListView"
android:layout_width="match_parent"
android:layout_height="389dp"
android:layout_alignParentLeft="true"
android:layout_alignParentTop="true"
android:isScrollContainer="false" />
<TextView
android:id="#id/android:empty"
android:layout_width="match_parent"
android:layout_height="80dp"
android:layout_above="#+id/editText1"
android:layout_alignParentLeft="true"
android:layout_alignParentTop="true"
android:fontFamily="sans-serif-light"
android:gravity="center"
android:text="#string/no_contacts"
android:textAppearance="?android:attr/textAppearanceLarge" />
<EditText
android:id="#+id/editText1"
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:layout_alignParentLeft="true"
android:layout_alignParentBottom="true"
android:background="#android:color/holo_blue_dark"
android:ems="10"
android:imeOptions="flagNoExtractUi"/>
</RelativeLayout>

Snapshots are:
Try using android:windowSoftInputMode="adjustResize|stateHidden" in your activity tag.
I have the same problem as yours with EditText inside a Relative layout before, after searching several thread all over internet I have failed, but I solve it by experimenting on it through adding bottom_padding to the EditText which fixed it.
try this code to manifest file and activity to change layout.
android:windowSoftInputMode="stateAlwaysVisible|stateHidden"
I'm trying to place a TextView at the bottom of every activity by using the include... My code is below... I don't know why, but it remains at top... Although it works fine for TextView.
<?xml version="1.0" encoding="utf-8"?>
<RelativeLayout xmlns:android="schemas.android.com/apk/res/android"
android:layout_width="fill_parent"
android:layout_height="match_parent"
android:background="#E0E0E0"
android:orientation="vertical" />
<include
android:layout_alignParentBottom="true"
android:id="#+id/footer"
layout="#layout/footer" />
<TextView
android:id="#+id/textView1"
android:layout_width="fill_parent"
android:layout_height="wrap_content"
android:gravity="center_horizontal"
android:layout_alignParentBottom="true"
android:text="Hello"
android:textColor="#000000"
android:textSize="15dp" />
¿Maybe you are using a LinearLayout instead of a RelativeLayout? The latter doesn't have android:orientation property. We don't see the parent XML node, so just a guess
Also, you'll need to place the include at the bottom and the TextView above it
<TextView
...
android:layout_above="#id/footer" />
Right now you are overlapping both views
Another suggestion is to use FragmentActivity and a Fragment to handle the Footer, but that's out of the scope of this question.
Use RelativeLayout in your same xml code as the parent layout.
Well i got the solution.... I had to add the include inside another child relative layout...This is what i did..
enter code here
RelativeLayout
android:layout_width="fill_parent"
android:layout_height="wrap_content" >
<include
android:id="#+id/footer"
android:layout_alignParentBottom="true"
layout="#layout/footer" />
</RelativeLayout>
but...for a textview it works directly without using another child layout...So why do you need to do this for an include.....????:|
I checked your code. It works fine as posted in 1st post.
Please note that when you use layout tag then Eclipse' Graphical Layout won't draw the child xml-layout you've included (in your case footer.xml).
At the same time, you'll get a footer like you want if you run same code on actual device or emulator.
NOTE: you might want to remove android:layout_alignParentBottom="true" from textView1 as currently textView1 and footer layouts overlaps.
I am trying to get three images to display on the "welcome screen" of my Android app. Only one of the images is being displayed, and I cant figure out why... any Help?
XML File:
<?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:gravity="center"
android:background="#drawable/main_bg"
>
<LinearLayout
android:orientation="horizontal"
android:layout_width="fill_parent"
android:paddingTop="30dip"
android:layout_height="wrap_content"
android:gravity="center"
>
<ImageButton
android:id="#+id/mnwvbutton"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:layout_marginRight="15dip"
android:background="#drawable/mnwvicon" />
<ImageButton
android:id="#+id/reportsbutton"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:background="#drawable/reportsicon" />
</LinearLayout>
<ImageButton
android:id="#+id/mnwvshowbutton"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:background="#drawable/showicon"
android:paddingTop="30dip" />
</LinearLayout>
I have the exact same set up in another app, so I dont know why it isnt working here??
I think its because the last image is outside the inner linearlayout so put it inside the inner linearlayout and you should be able to see all three images in a row.
Try scaling the images using the attribute android:ScaleType="centre" inside the ImageButton
or try a different layout like Tablayout for arranging the images in rows and columns with proper spacing.
Sorry guys. I didnt have the app support the different screen sizes. I am not sure why this mattered, but once I added support, then it worked perfectly!. Thanks for your input though! Anyone know why this mattered though?? I dont know why supporting screen sizes matters?
