how to move (up/down) code lines in android studio?

问题

In eclipse we use Alt + ↑/↓ to move line up or down.

Is there any shortcut in android studio do the same? Or any quick way to avoid copy & paste?

回答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.

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"

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. ;-)
