Import .activity_main.*Ĭlass MainActivity : AppCompatActivity(), View.
When I drag a button object into the activitymain.xml,it does not show me the 'onclick' option under the 'Declare Attributes'. In this class, we also create a Button programmatically (button4), define its properties and set it on the layout. Im currently learning to make apps in android studio. e OnClick handler causes the animation to start and run. In this class, we implement the setOnClickListener listener on the button, implements the OnClickListener of View class ( View.OnClickListener) and override its function onClick.

Public class MainActivity extends AppCompatActivity implements View.Add the following code in the MainActivity.kt class. However I can't then seem to access this updated difficulty outside that method.Īlso, as a side question, I can't run the Log command (as shown above), but when I run it inside my method it's fine. Then when someone clicks the easy button, it sets difficulty = "easy". Initialize the difficulty variable as a string. Public void easyButtonFunction(View view) Log.i("Difficulty", difficulty) To do this, within my main class, I coded this: String difficulty Here is minimalist android application to connect to either superuser or stackoverflow with 2 buttons. Here is the official link event handler snippet. I can then pass this to my next activity and use it there. If you are talking about an RCP app, then what you need is the SWT link widget. (Didnt know that.) Still, extracting it into a separate method seems cleaner.
Edit: As per st0les comment, you can do what you want by calling clr.performClick(). Lately android added a xml attribute to views called android:onclick, that can be used to. Step 1 Create a new project in Android Studio, go to File New. OnClickListener is what waits for someone to actually click, onclick determines what happens when someone clicks. Based on the View passed into onClick (), you will know which ImageView was clicked. Quickly bring your app to life with less code, using a modern declarative approach to UI, and the simplicity of Kotlin.

My thinking was that in my java file, I can then set an onClick method per button, such that clicking the button will update a "difficulty" variable. You want to call the first onClick from the second Just extract the contents of your first onClick in a separate method and call that method from each onClick. In Android, the OnClickListener() interface has an onClick(View v) method that is called when the view (component) is clicked. Difference Between OnClickListener vs OnClick: OnClickListener is the interface you need to implement and can be set to a view in java code. What I have done is create an activity with three buttons.
I want my button, when it's clicked on the phone to switch the layout view from main.xml to xx. I am making a difficulty screen (select easy/medium/hard).
