如何找到在 Android Studio 中使用方法或变量的位置（快捷方式）

Question

I know how to find the source by using ctrl + left click on a method, for example, but what if I want to find where this method is used? I'm using Windows 7.

Let's suppose I have the following method:

class A {
    public int sum(int a, int b) {
        return a+b;
    }
}

and I am using this method in

class B {
    ...
    a.sum(c, d);
    ...
}

and I want to find where I used sum while I was in class A .

PS: I'm new to Android studio (started using it about a month ago).

Answer 1

In Android Studio, highlight the method and either right click > Find usages or use the Alt + F7 shortcut.

Edit: Ctrl + left click on a method is useful for finding where that method was initially declared

Answer 2

For Ubuntu users:

For me Alt + F7 has not worked, so I've solved the conflict by going to the

Ubuntu System settings-> keyboard -> shortcuts

and changing Alt + F7 in there with another combination.

And now it's working ))

Answer 3

只需单击方法或变量，任何用法都会突出显示，在代码右侧的滚动条上，您会看到灰色条出现，这些是当前突出显示（或单击）的变量或方法在您的代码中的用法代码。

Answer 4

To find all uses of a variable or method in Android Studio you can use

1. ctrl+shift+F7(window/Ubuntu)
2. after that for navigation purpose you can use F3

Answer 5

Here are different key shortcuts for displaying method or variable usage. The keymaps with F14 in them were added by me; the others are default. For Windows (and Linux?), replace the ⌘ key with Ctrl (I think). Find Usages shows them in a dedicated window in Android Studio (the solution in other answers), while Show Usages puts them in a popup (second image below).

Answer 6

使用 [Ctrl+b] 或 [Ctrl+Alt+b] 导航到方法的原点或变量的清除和实现

Answer 7

Ubuntu is Ctrl+Alt+7 or Ctrl+b to show the usage of the class. Ctrl+Alt+F7 is not work.
