Use the input tool to send button events

Key events are sometimes used during Android development and testing. However, for other reasons, it is not very convenient to use the keyboard or mouse to click each time. Here is an adb tool-input tool.

Using the input tool is actually very simple. first enter the adb shell, and then enter:
[Plain]
# Input keyevent <keycode>
Or enter the following directly at the terminal:
[Plain]
$ Adb shell input keyevent <keycode>
<Keycode> indicates the key code, which is defined in the header file $ ANDOIRD/frameworks/base/include/ui/KeycodeLabels. h, as follows:
[Cpp]
Static const KeycodeLabel KEYCODES [] = {
{"SOFT_LEFT", 1 },
{"SOFT_RIGHT", 2 },
{"HOME", 3 },
{"BACK", 4 },
{"CALL", 5 },
{"ENDCALL", 6 },

// NOTE: If you add a new keycode here you must also add it to several other files.
// Refer to frameworks/base/core/java/android/view/KeyEvent. java for the full list.
 
{NULL, 0}
};
The input tool is not only used in adb shell, but can also be used in C/C ++ code:
[Cpp]
Sprintf (s_keyArray, "input keyevent % d", keycode );
System (s_keyArray );
In this way, you can directly send a button event to the system.
