代码：

preferences = getSharedPreferences("count",MODE_WORLD_READABLE);  int count = preferences.getInt("count", 0);    //判断程序与第几次运行，如果是第一次运行则跳转到引导页面  if (count == 0) {  Intent intent = new Intent();  intent.setClass(getApplicationContext(),LaunchGuideViewActivity.class);  startActivity(intent);  this.finish();  }  Editor editor = preferences.edit();  //存入数据  editor.putInt("count", ++count);  //提交修改  editor.commit();
