【android】android使用命令模拟按键

可以使用如下命令模拟android按键。

input keyevent keycode

keycode为具体的按键值，常用的如

HOME键为3，BACK键为4。

具体按键值在android中的定义如下：

    field public static final int ACTION_DOWN = 0; // 0x0    field public static final int ACTION_MULTIPLE = 2; // 0x2    field public static final int ACTION_UP = 1; // 0x1    field public static final android.os.Parcelable.Creator<android.view.KeyEvent> CREATOR;
