I put three buttons on my form, the focus is on the first one.
There's no response to the navigation buttons and i can't get to the other two buttons.
There's also no response to the main button (the first button isn't clicked).
I added action listeners and used setNextFocusRight() and nothing works.
What else do I need to do to enable navigation between components?
I believe your problem is that you haven't loaded any theme and all your buttons look the same (white or something). Navigation is working fine, but you can't see the result of pushing DOWN button.
addMnemonic is what you need i guess. Read this I think it will help you ))

I'm writing an Android application in Android Studio on Java.
I know that there is android:focusable="false", but I have too many files for doing this with every tag in XML.
How can I prevent all of them from being focused? Or maybe there is some ways that I can do it easier?
The only way I could think of is creating BaseActivity and BaseFragment classes and in onCreate and onViewCreated recursively go through all the views and call setFocusable(false).
Here is an answer how to do it recursively:
Loop through all subviews of an Android view?
Also here I handled a case with a recursion myself. I have posted an answer:
Toolbar is hidden in nested PreferenceScreen

I want to crate an dropdown menu which opens form down to top when I click an icon on an circle fixed in the left-bottom corner.
Which Elements should I combine (no code answers necessary)
Example draft
Creating a Spinner near the bottom of an activity should force it to open upwards, given there isn't enough space to list downwards. A way of forcing using this would be to add a margin to the top of your spinner to force it down so it will list upwards.

I would like to create a picture/button that is displayed over the content of an activity and I can move it anywhere on the screen. Example of functionality: If I move it close to the left side of the screen I would like the image to move to the edge when the user drops the object.
You can either use a draggable view library like DraggableView or you can implement your own onTouch handling to handle touch events for dragging image view. Here's an article for reference.

When I close to "Gelir Ekleme Alanı" then the main page close too. What am I doing for avoid this problem. It is my school homework and I must solve the problem.
enter image description here
I guess that you are in your JFrame saying something like
GelirEklemeAlanıFrame.setDefaultCloseOperation(JFrame.EXIT_ON_CLOSE);
which makes the JFrame execute
System.exit(0);
when you press the red X which closes your whole application. But as you just want to close the window you have to change it to
GelirEklemeAlanıFrame.setDefaultCloseOperation(JFrame.DISPOSE_ON_CLOSE);
which just closes this frame or create a custom exitListener. If you want to make a custom exitListener to add some extra behaviors on exit, just look up on the internet for "exitListener in java swing" or JFrame.
Hope I helped you :) Good luck in school!

I'm currently making a mortgage calculator, but I need some help. I have a reset button on my GUI that makes all of the forms blank again after typing something into them. The IDE already helped me make the button, so here is where I'm at:
private void resetActionPerformed(java.awt.event.ActionEvent evt) {
// TODO add your handling code here:
}
What do I need to put in here?
You either recreate your complete GUI (probably not an option), or painstakingly use .setText("") against each and every input field you have, and similar logic for radio buttons, etc. There's no royal way to it, unfortunately.
