开发中常见坑

1.点击跳转到另一个页面时，为防止因为系统或网络响应慢而出现连续出现多个对象窗口，在点击一次之后 设置其clickble为false

2.在调用某个功能之前 先检查有没有权限 类似下面

PackageManager pkm = getPackageManager();

boolean has_permission = (PackageManager.PERMISSION_GRANTED == pkm.checkPermission("android.permission.RECORD_AUDIO", "packageName"));

if (has_permission) {

这里才开始真的干活的

}else {

showToast("没有权限");

}
