am an upcoming android developer. I have my app in eclipse running on 2.2 android platform and the only thing remaining is adding fancy buttons to it. I have designed some buttons using photoshop but my main problem is to get the right dimensions (width, height and pixels) for my button so that they can fit properly on the screen. Please help! Thank you.
lucky for you, android sdk comes with a tool that allows you to adjust which parts of your image can be stretched, and which shouldn't be (as i'm thinking that's what you're worrying about). it's called 9-patch, and you can read about it here
What you have to do is play with your .xml file. You have to adjust your Buttons's properties like width and height and that will do.
Start playing with this for example:
<?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" >
<Button
android:id="#+id/button1"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:height="50sp"
android:width="100sp"
android:background="#drawable/my_image"
android:text="I'm a button"
/>
</LinearLayout>

Recently, while working on some projects, I've had a rather annoying problem when coding the user interface of my application. The problem is, some controls (usually a floating action button or a regular button) render strangely. It's hard for me to explain exactly how it looks - but here's an example of how it shows the floating action button to look like in the designer:
Code:
<?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:layout_width="match_parent"
android:layout_height="match_parent"
android:baselineAligned="false"
xmlns:app="http://schemas.android.com/apk/res-auto"
android:orientation="vertical"
tools:context=".MainActivity">
<com.google.android.material.floatingactionbutton.FloatingActionButton
android:layout_width="wrap_content"
android:src="#drawable/ic_baseline_add_24"
android:layout_height="wrap_content"/>
</LinearLayout>
Now, the thing is, I don't have any weird or special code added, the XML code is as pure as it gets, so I have no idea why I am having these strange rendering problems.
Here is how it rendered the following button:
Code:
<com.google.android.material.button.MaterialButton
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:text="Submit"
android:layout_gravity="bottom"
android:textAllCaps="false"
android:layout_margin="30dp"
app:cornerRadius="30dp"
android:id="#+id/submitButton"
android:backgroundTint="#color/turquoise"
/>

A solution would be greatly appreciated!
Cheers,

Solution is simple u just need to restart your android rendering engine. I provided Image for your context . In android studio top right corner above layout display there is Toggle issue panel click on that and u will see one box in the bottom showing rendering issue restart rendering engine and that will restart your android studio. and u good to go. try this solution and let me know your issue is solved or not.
note: In my Image I already restarted so there is no option for restart rendering engine .but in yours's U may be find hope so.

app description :-
simple app with listView (orientation : horizontal)
the problem is :-
when i run the app on a real device , i found that all views direction get reversed
this is an item on android studio:-
app preview on android studio
but when it run on a real device it look like this
app on a real device
this is my layout (item.xml) code
<?xml version="1.0" encoding="utf-8"?>
<LinearLayout

android:textColor="#302f2f"
android:textSize="18sp"/>
</LinearLayout>
i want to display the same design from android studio preview on the real device
with the same view direction.
so what is the problem and how i can fix this.
This is due to difference between the screen size and display resolution, the layout that you're designing in the studio might look good on that exact screen size or resolution that you've selected in the layout editor, but that might not be the case for every device, your device in this case.
You can refer this thread for more detailed solution to your problem
you should check two or three things:
1- is your ListView parent layout has layoutDirection in XML?
2- have you called the method getWindow().setLayoutDirection(LayoutDirection.RTL) any where in your code?
3- if your list activity or fragment does not have number 2 then you should check your adapter class to see if there is any code written about ItemView direction.
4- if non of this is relevant for you please try changing preview android version and preview size.
hope this helps.
I am very new to this forum and really need help in something I got stuck in during developing the app.
This is the image I am using as my background (I named it SampleBG in xml):
https://i.gyazo.com/946507c2690c8170b54a1ace752906bd.png
Basically, this is what I want my design to look like:
https://i.gyazo.com/896e29846dfd9e4bc9ab15ca39f9a796.png
And for smaller devices, it automatically resizes and looks like this:
[i.gyazo.com/f4278339cc8f246187c011474796a12c.png]
And when I switch to a tablet device, it automatically looks like this:
[i.gyazo.com/1b0e233a0b1731148664e0ac78a05f08.png]
And the above is exactly what I want it to look like. The wooden signs are in the same position for all sizes...
But the problem is:
I want the wooden signs to be clickable, because they are meant to be buttons.
So, I tried to use a button widget and made it transparent and placed it over the wooden signs... it worked but it only worked for that particular size I designed it for (designed it for Nexus 5 to be specific).... However, when I switched to the Nexus One layout, or Nexus 9 layout, etc, the buttons weren't placed correctly over the wooden signs and thus didn't work.
I want a way to make the wooden signs clickable and and the buttons to be fixed with the signs for all device sizes/etc, and at the same time.
I would prefer an xml solution but a programmatic solution is nice too.
Here's the layout code right now, it just using the background image right now....
`<?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:background="#drawable/sampleBG">
</RelativeLayout>`
NOTE:
I have tried using the door image as the background only and then adding the wooden signs manually by using the ImageButton widgets, but the wooden signs were being placed differently for different screens and it looked odd, so therefore I fixed the wooden signs with the background (in Photoshop).. now I just want the signs to be clickable.
This is a sample code that you can use, in order to achieve this:
<?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"
android:background="#mipmap/ic_launcher"
android:paddingBottom="#dimen/activity_vertical_margin"
android:paddingLeft="#dimen/activity_horizontal_margin"
android:paddingRight="#dimen/activity_horizontal_margin"
android:paddingTop="#dimen/activity_vertical_margin"
tools:context="com.test.androidtestapp.MainActivity">
<ImageButton
android:id="#+id/equationsButton"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:layout_above="#+id/equationsOfTheWeekButton"
android:layout_centerInParent="true"
android:layout_margin="20dp"
android:background="#mipmap/ic_launcher"
android:contentDescription="Equations Button"
android:onClick="equationsButtonClick" />
<ImageButton
android:id="#+id/equationsOfTheWeekButton"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:layout_centerInParent="true"
android:layout_margin="20dp"
android:background="#mipmap/ic_launcher"
android:contentDescription="Equations Of The Week Button"
android:onClick="equationsOfTheWeekButtonClick" />
<ImageButton
android:id="#+id/settingsButton"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:layout_below="#+id/equationsOfTheWeekButton"
android:layout_centerInParent="true"
android:layout_margin="20dp"
android:background="#mipmap/ic_launcher"
android:contentDescription="Settings Button"
android:onClick="SettingsButtonClick" />
</RelativeLayout>
You need to slice your image and then just change the background attributes in the code above. When you achieve that, you can change the background to a selector where you can change the image depending on the different states -> when it's clicked, focused, normal; that would make it more user friendly.
The wooden signs should NOT be on the background image.
Instead, make a real background image (ie. with only the "door" background) and make separate images with the signs.
Then use these images to build your buttons.
Edit: I did read your note about the fact that you tried that, but you should definitively go this way. Another advantage is that you'll be able to easily make the buttons reacting to the user click, with "onPress" states, which would be impossible (or at least difficult and ugly) with a single background image.
You can separate wood pics that you want to be button and give them as a background for buttons. For example, you named the wooden pics as 'wood1.png' , 'wood2.png' and 'wood3.png' and by this sample code you can set them for background image for buttons :
<ImageButton
android:id="#+id/button1"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:background="#drawable/wood1"
/>
Or you can design your app by your own solution that described but you should create your app design by different layout for different size device :
layout-large
layout-small
layout-normal
layout-xlarge
layout-xxlarge
you can search about autoLayout design in android app and find your solution better..
I am developing my first Android app. Although I have 15 years of Java software development experience, Android is new to me. My desired look is a background image with other images on top of it, as well as labels and phone numbers. It seems like the best way to accomplish this is a Linear Layout for the background image, with a nested layout for the other fields on top of that. I have searched online and cannot find any sample code on how to accomplish this. Any recommendations would be greatly appreciated. Thanks in advance.
What are you using to develop? If you are you using Eclipse with the Android SDK this is super easy. Put the desired picture in the appropriate drawable folder, go to the graphical view of layout that corresponds to your activity, on the right side of the screen there is a list of all the properties, find background, then select your picture from drawables. You can also do this from the xml using android:background="#drawable/yourPic". This way you don't have to worry about having things layered on top of it.
I think you should go through followings:
1. http://phandroid.com/2011/05/11/10-tips-for-android-ui-design/
2. http://mobile.tutsplus.com/series/android-user-interface-design/

4. http://android-developers.blogspot.in/2011/09/thinking-like-web-designer.html
If I got, something like this can work:
<RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:layout_width="fill_parent"
android:layout_height="fill_parent" >
<stuff>
<RelativeLayout
android:layout_width="fill_parent"
android:layout_height="fill_parent" >
<stuff>
</RelativeLayout>
<stuff>
</RelativeLayout>
I used it in an app, and made the trick.
First of all, RelativeLayout is the best layout to use. It depends on your design.
If your design says to keep all the views either vertically OR horizontally, you can use LinearLayouts in between.
My suggested way:
<RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:layout_width="match_parent"
android:layout_height="match_parent" >
<LinearLayout android:id="#+id/layout1"
android:layout_width="match_parent"
android:layout_height="wrap_parent"
android:orientation="Horizontal">
<View1 />
<View2 />
</LinearLayout>
</LinearLayout android:id="#+id/layout2"
android:layout_width="match_parent"
android:layout_height="wrap_parent"
android:orientation="Vertical"
android:layout_below="#id/layout1">
<View3 />
<View4 />
</LinearLayout>
</RelativeLayout>
Which will yield you something like this
Anyone know of any open source implementation of a slide toggle for android. The default android toggle(ToggleButton) is not pretty. I am looking for anything similar to iOS. I should be able to implement one from scratch. But if anything similar is already available, then i can build on it.
Thanks in advance to the wonderful stackoverflow community.
Edit1:
What I meant by iOS Slide Toggle is UISwitch
Edit2: Just want to summarize the answer. Commonsware provided the clue. I ended up back porting the Switch code from 4.0 to2.2.2. Thanks to the open-sourced code, back porting was not very difficult. The code is hosted on git hub. http://github.com/pellucide/Android-Switch-Demo-pre-4.0/tree/master/
A screenshot from that project
you can use the sliding drawer widget in android to have a sliding toggle switch. you just have to "slice" the ios toggle images into3 parts, one for the handle, one for the sliding drawer background and one for the content part. then put an image on top of it like a frame to give you the "round edges"
here's what i've come up with:
XML Layout
<?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" >
<FrameLayout
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:layout_gravity="center_horizontal"
android:layout_marginTop="100dp" >
<SlidingDrawer
android:id="#+id/slidingDrawer1"
android:layout_width="154dp"
android:layout_height="54dp"
android:background="#drawable/ios_retina_toggle_on_full"
android:content="#+id/content"
android:handle="#+id/handle"
android:orientation="horizontal" >
<ImageButton
android:id="#+id/handle"
android:layout_width="54dp"
android:layout_height="54dp"
android:background="#00000000"
android:src="#drawable/ios_retina_toggle_button" />
<ImageView
android:id="#+id/content"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:src="#drawable/ios_retina_toggle_off" />
</SlidingDrawer>
<ImageView
android:id="#+id/imageView2"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:src="#drawable/ios_retina_toggle_frame" />
</FrameLayout>
</LinearLayout>
ios_retina_toggle_on_full
ios_retina_toggle_button
ios_retina_toggle_off
ios_retina_toggle_frame
and finally a screenshot of how it looked on the emulator on a 3.7 WVGA screen running gingerbread:
iOS does not seem to have a "slide toggle", at least under that name, based on a Google search. And, you did not provide an image (or a link to an image) of what you want.
Android 4.0 added a Switch that you might be able to backport to earlier versions. You will see samples of it in the API Demos app on your emulator:
You can try using ToggleButton specifying your own drawables for its states.
We can try using seekbar with custom drawables and thumb, setting the max value to 1 and min to 0. we can add animations for sliding effect
