Is there a shortcut in Android Studio for automatically generating the getters and setters in a given class?
Using Alt+ Insert for Windows or Command+ N for Mac in the editor, you may easily generate getter and setter methods for any fields of your class. This has the same effect as using the Menu Bar -> Code -> Generate...
and then using shift or control button, select all the variables you need to add getters and setters
for macOS, ⌘+N by default.
Right-click and choose "Generate..." to see current mapping. You can select multiple fields for which to generate getters/setters with one step.
See http://www.jetbrains.com/idea/webhelp/generating-getters-and-setters.html
Android Studio & OSx :
Press cmd+n > Generate > Getter and Setter
Android Studio & Windows :
Press Alt + Insert > Generate > Getter and Setter
create the variable
right click
select "Generate" and then select "Getter and Setter" option
Android Studio & Windows :
fn + alt + insert
You can generate getter and setter by following steps:
Declare variables first.
click on ALT+Insert on keyboard placing cursor down to variable declaration part
now select constructor and press Ctrl+A on keyboard and click on Enter to create constructor.
Now again placing cursor at next line of constructor closing brace , click ALT+INSERT and select getter and setter and again press CTRL+A to select all variables and hit Enter.
That's it. Happy coding!!
Position the cursor under the variables -> right-click -> Generate -> Getter and Setter -> Choose the variables to make the get and set
or
Alt + Insert -> Getter and Setter -> Choose the variables
As noted here, you can also customise the getter/setter generation to take prefixes and suffixes (e.g. m for instance variables) into account. Go to File->Settings and expand Code Style, select Java, and add your prefixes/suffixes under the Code Generation tab.
Using Alt+ Insert or Right-click and choose "Generate..."
You may easily generate getter and setter or Override methods in Android Studio.
This has the same effect as using the Menu Bar Code -> Generate...
This answer deals with your question but is not exactly an answer to it. =) It's an interesting library I found out recently and I want to share with you.
Project Lombok can generate common methods, such as getters, setters, equals() and hashCode(), toString(), for your classes automatically. It replaces them with annotations reducing boilerplate code. To see a good example of code written using Lombok watch a video on the main page or read this article.
Android development with Lombok is easy and won't make your android application any 'heavier' because Lombok is a compile-time only library. It is important to configure your Android project properly.
Another example:
import lombok.Getter;
import lombok.Setter;
public class Profile {
#Getter #Setter
private String username;
#Getter #Setter
private String password;
}
Android development with Lombok is possible. Lombok should be a compile-time only dependency, as otherwise the entirety of Lombok will end up in your DEX files, wasting precious space. Gradle snippet:
dependencies {
compileOnly "org.projectlombok:lombok:1.16.18"
}
In addition you may want to add the Lombok IntelliJ plugin to support Lombok features in your IDE at development time. Also there is Hrisey library which is based on Lombok. Simply put, it's Lombok + Parcellable support.
You can use AndroidAccessors Plugin of Android Studio to generate getter and setter without m as prefix to methods
Ex: mId;
Will generate getId() and setId() instead of getmId() and setmId()
Use Ctrl+Enter on Mac to get list of options to generate setter, getter, constructor etc
use code=>generate=>getter() and setter() dialog ,select all the variables ,generate all the getter(),setter() methods at one time.
Another funny way
Type the parameter name anywhere in the object after definition, you will see setter and getter, Just select and click enter :)
I tried with Android Studio 2.3
Right click on Editor then Select Source -> Generate Getters and Setters or press Alt + Shift + S
Just in case someone is working with Eclipse
Windows 8.1 OS | Eclipse Idle Luna
Declare top level variable private String username Eclipse kindly generate a warning on the left of your screen click that warning and couple of suggestions show up, then select generate.

I'm using this NetResource class to send files to a network drive and it looks like this:
[StructLayout(LayoutKind.Sequential)]
public class NetResource
{
public ResourceScope Scope;
public ResourceType ResourceType;
public ResourceDisplayType DisplayType;
public int Usage;
public string LocalName;
public string RemoteName;
public string Comment;
public string Provider;
}
Now it's very important that the order of these fields stay the same, as hinted on by the StructLayout attribute.
However, when someone would run a resharper cleanup, resharper decides to move the fields around and that would break the code.
Is there any way of telling rehsarper to not mess with it? I feel like if I can't do that, someone is going to eventually break the code and have no idea where to look.
But a mediocre solution to that I think would be to create a unittest that can check if there layout is as expected.
Edit: I've seen this answer, but it is outdated and requires resharper settings to be updated. I will also not be guaranteed that coworkers use this resharper setting. I'm looking for a way to add it in the code, just like you can do // ReSharper disable once InconsistentNaming
I see a couple of solutions here:
You might mark the class with NoReorderAttribute from the JetBrains.Annotations (there are several ways to add them to a project). Then ReSharper will stop reordering members inside the marked code entity.
It is mostly about already mentioned answer, I will show you how to get the same things in last ReSharper builds. All you need is to add "System.Runtime.InteropServices.StructLayoutAttribute" to "Non-reorderable types" pattern in ReSharper | Options | Code Editing | C# | File Layout.
Step 1:
Step 2:
Step 3:
Step 4:
Step 5:
To make sure your colleagues use the same settings in ReSharper, save this change to the Solution team shared layer (Save To at the bottom of the Options dialog). Then if any of your colleagues opens the solution, ReSharper will automatically use the setting from this layer with no additional actions required.
When I programmed with Android Studio, it seems to me that is a way to generate automatically the getter and the setter of my new java class.
Can anyone tell me how to do it?
Open the class you want, right click anywhere in the code and chose the Generate option:
Then chose what you are trying to generate: setters, getters or both:
Then select the fields you want, and you're done.
Resharper 2016.1 is notify unused public methods. Is there a way to disable this notifications global? I want only disable notification of unused public methods. Unused private methods should be notified nevertheless.
You'll need to turn off Solution Wide Analysis (ReSharper → Options → Code Inspection Settings). This will disable a number of inspections, but also disable marking public methods as being unused. Alternatively, you can use ReSharper's annotations, and add an attribute such as [PublicAPI] to the public methods that are used externally.
Private methods will remain marked as unused, because that only requires ReSharper to analyse a single class, rather than the whole solution.
I have resharper 2018.1. I don't know if this is version specific but in addition to #citizenmatt's answer you also need to make sure that "Show non-private type members when solution-wide analysis is off" is unchecked on the same options page. You could search for 'solution wide' in top left search of resharper options to quickly get on that page as per the image below.
I am new in Android app development and using Java language.
My problem is every time I make a TextView or Button there is a triangle with the exclamation mark below them.
and when I click it I saw a message saying:
hardcoded string “Button”, should use #string resource
I have two activities, in my main activity there is a Button that when you click it you will go in second activity.
But when I go to my main.java to make a code for the button. There's always the above shown error. I think the eclipse can't find the id of my button and same for my TextView they have same error message.
Here is the code I made:
Button b = FindViewById(R.id.button1);
I also add:
Button b = (Button) FindViewById(R.id.button1);
I am using the latest eclipse classic and ADT august issue. The platform is Android 4.1 API 16.
You shouldn't hardcode the "text" on the widgets use the strings resources ie., strings in the strings.xml to set the text. Declare the "text" you want to display as a string in strings.xml and access it using #string/your_string_name in the layout file.
Notice the id of the button, which is rounded in red. You have to use this id when you want to call it in a method, for an example
Button b = (Button) FindViewById(R.id.button1);
Furthermore, check whether your graphical layout matches with the image I have provided.
Just try your code again with these changes.
Your main.java would look like this.
I am a newbie too, but I believe I got this. So basically what's happening here, java wants you to put your hardcodes in string.xml. so that when accessing it, you will use the given methods below before:
.
But this is how it should be.
Let's start by string.xml
Then come back to your activity_main.xml
In xcode 3 there was a helpful feature in the data model builder where you could highlight some attributes/relationships in an entity, right-click, and choose to copy method and property declarations to the clipboard. (You could choose if you wanted objective-c 2.0 property declarations also). Then you could paste them into your NSManagedObject subclass.
I see how you can still generate the entire class file; but this isn't helpful if you are adding attributes to an existing entity. Have they removed this feature from xcode 4? I used it all the time!
See the Core Data Model Editor Help: Creating Objective-C Accessor Methods for a Managed Object
You may find MoGenerator useful.
Watch out for the fact that the special paste menu item only appears in the Edit menu not the contextual menu in the source editor.
