How to move (up/down) code lines in Android Studio?

Solution 1:

To move a line:

Place the caret at the line to be moved.

Do one of the following:

On the main menu, choose Code | Move Line Up or Code | Move Line Down.

Press Shift+Alt+Up or Shift+Alt+Down.

Solution 2:

If you want the exact behavior of eclipse you can do this:

File --> Settings --> Keymap --> Code--> Folding--> assign Alt+↑/↓ to "Move Line Up/down" instead of "Move Statement up/down"

Solution 3:

There are (at least) two kinds of Moving line up/down in Android Studio: The "intelligent" one and the "dumb" one. Like IngoAlbers said, the dumb one (Shift+Alt+<Arrow>) just moves the line.

Using Ctrl+Shift+<Arrow> instead, makes the functionality more intelligent:

• It doesn't leave the current "context":

  public static void test() {
      int i = 5;
      Runnable theodor = new Runnable() {
          public void run() {
              System.out.println("Hi!");
          }
      };
  }
  

  Moving the int i = 5;line down one step, brings you this:

  public static void test() {
      Runnable theodor = new Runnable() {
          public void run() {
              System.out.println("Hi!");
          }
      };
      int i = 5;
  }
  

• It keeps methods together:

  public static void hello() {
      System.out.println("Hello!");
  }
  
  public static void dinner() {
      System.out.println("Dinner's ready!");
  }
  
  public static void sleep() {
      System.out.println("Good night.");
  }
  

  Moving the line public static void sleep() { up one step moves the complete sleep() method above dinner():

  public static void hello() {
      System.out.println("Hello!");
  }
  
  public static void sleep() {
      System.out.println("Good night.");
  }
  
  public static void dinner() {
      System.out.println("Dinner's ready!");
  }
  

• In most cases, it is just annoying. ;-)

Solution 4:

In windows, you can go to 'Keymap' settings(File --> Settings --> Keymap --> Editor Actions) to customize this action and more actions.

I think it's a better way.
