android 实现模拟按键

android 实现模拟按键方法一

通过Runtime实现，代码如下：

try{String keyCommand = "input keyevent " + KeyEvent.KEYCODE_MENU;Runtime runtime = Runtime.getRuntime();Process proc = runtime.exec(keyCommand);}catch (IOException e){// TODO Auto-generated catch blocke.printStackTrace();}

这个代码是模拟菜单键，模拟其它按键只需将KeyEvent.KEYCODE_MENU替换成其它键值。

缺点：反应速度较慢

以下附带各KeyCode值：

KEYCODE_UNKNOWN=0; KEYCODE_SOFT_LEFT=1; KEYCODE_SOFT_RIGHT=2; KEYCODE_HOME=3; KEYCODE_BACK=4; KEYCODE_CALL=5; KEYCODE_ENDCALL=6; KEYCODE_0=7; KEYCODE_1=8; KEYCODE_2=9; KEYCODE_3=10; KEYCODE_4=11; KEYCODE_5=12; KEYCODE_6=13; KEYCODE_7=14; KEYCODE_8=15; KEYCODE_9=16; KEYCODE_STAR=17; KEYCODE_POUND=18; KEYCODE_DPAD_UP=19; KEYCODE_DPAD_DOWN=20; KEYCODE_DPAD_LEFT=21; KEYCODE_DPAD_RIGHT=22; KEYCODE_DPAD_CENTER=23; KEYCODE_VOLUME_UP=24; KEYCODE_VOLUME_DOWN=25; KEYCODE_POWER=26; KEYCODE_CAMERA=27; KEYCODE_CLEAR=28; KEYCODE_A=29; KEYCODE_B=30; KEYCODE_C=31; KEYCODE_D=32; KEYCODE_E=33; KEYCODE_F=34; KEYCODE_G=35; KEYCODE_H=36; KEYCODE_I=37; KEYCODE_J=38; KEYCODE_K=39; KEYCODE_L=40; KEYCODE_M=41; KEYCODE_N=42; KEYCODE_O=43; KEYCODE_P=44; KEYCODE_Q=45; KEYCODE_R=46; KEYCODE_S=47; KEYCODE_T=48; KEYCODE_U=49; KEYCODE_V=50; KEYCODE_W=51; KEYCODE_X=52; KEYCODE_Y=53; KEYCODE_Z=54; KEYCODE_COMMA=55; KEYCODE_PERIOD=56; KEYCODE_ALT_LEFT=57; KEYCODE_ALT_RIGHT=58; KEYCODE_SHIFT_LEFT=59; KEYCODE_SHIFT_RIGHT=60; KEYCODE_TAB=61; KEYCODE_SPACE=62; KEYCODE_SYM=63; KEYCODE_EXPLORER=64; KEYCODE_ENVELOPE=65; KEYCODE_ENTER=66; KEYCODE_DEL=67; KEYCODE_GRAVE=68; KEYCODE_MINUS=69; KEYCODE_EQUALS=70; KEYCODE_LEFT_BRACKET=71; KEYCODE_RIGHT_BRACKET=72; KEYCODE_BACKSLASH=73; KEYCODE_SEMICOLON=74; KEYCODE_APOSTROPHE=75; KEYCODE_SLASH=76; KEYCODE_AT=77; KEYCODE_NUM=78; KEYCODE_HEADSETHOOK=79; KEYCODE_FOCUS=80;//*Camera*focus KEYCODE_PLUS=81; KEYCODE_MENU=82; KEYCODE_NOTIFICATION=83; KEYCODE_SEARCH=84; KEYCODE_MEDIA_PLAY_PAUSE=85; KEYCODE_MEDIA_STOP=86; KEYCODE_MEDIA_NEXT=87; KEYCODE_MEDIA_PREVIOUS=88; KEYCODE_MEDIA_REWIND=89; KEYCODE_MEDIA_FAST_FORWARD=90; KEYCODE_MUTE=91;
