方法一：按两次退出程序

        /**         * 按返回按钮 */@Overridepublic boolean onKeyDown(int keyCode, KeyEvent event) {if (keyCode == KeyEvent.KEYCODE_BACK) {long thisTime = System.currentTimeMillis();if(thisTime > mBackTime && (thisTime-mBackTime)<3000 && mBackTime!=0){tag = 1;tag_page = -1;if(null!=Constant.gongDanInfoArr){Constant.gongDanInfoArr.clear();Constant.gongDanInfoArr= null;}stopService(new Intent(this, GPSService.class));ReceiveGongDanService.myTag = 0;finish();}else{Toast.makeText(this, "再按一次退出系统!", Toast.LENGTH_SHORT).show();mBackTime = thisTime;}}return false;}

方法二：提示退出程序

/** * 按返回按钮 */@Overridepublic boolean onKeyDown(int keyCode, KeyEvent event) {// 创建退出对话框AlertDialog isExit = new AlertDialog.Builder(this).create();// 设置对话框标题                       isExit.setTitle("温馨提示");// 设置对话框消息isExit.setMessage("确定要退出吗？");// 添加选择按钮并注册监听isExit.setButton("确定", listener);isExit.setButton2("取消", listener);// 显示对话框isExit.show();}return false;}/** 监听对话框里面的button点击事件 */DialogInterface.OnClickListener listener = new DialogInterface.OnClickListener() {public void onClick(DialogInterface dialog, int which) {switch (which) {case AlertDialog.BUTTON_POSITIVE:// "确认"按钮退出程序tag = 1;tag_page = -1;if(null!=Constant.gongDanInfoArr){Constant.gongDanInfoArr.clear();Constant.gongDanInfoArr = null;}finish();break;case AlertDialog.BUTTON_NEGATIVE:// "取消"第二个按钮取消对话框break;default:break;}}};

方法三：模拟QQ，微信等退出sss

1.将程序退出到后台运行，只是假退出

@Override      public boolean onKeyDown(int keyCode, KeyEvent event) {          if (keyCode == KeyEvent.KEYCODE_BACK) {              moveTaskToBack(false);              return true;          }          return super.onKeyDown(keyCode, event);      }

2.将程序完全退出

/** * 退出程序 */public void quit(){stopService(new Intent(this, GPSService.class));stopService(new Intent(this, ReceiveGongDanService.class));finish();}
