关于dialog报错问题:Expected receiver of type android.app.AlertDialog, but got java.lang.ref.WeakReference
miskiyang opened this issue · comments
我的compileSdkVersion 30
MessageDialog里面的showEvent方法反射获取AlertController报错,这个对象已经被标为@UnsupportedAppUsage,
不允许反射拿了,博主更新处理下这个问题
报错信息:
java.lang.IllegalArgumentException: Expected receiver of type android.app.AlertDialog, but got java.lang.ref.WeakReference
W/System.err: at java.lang.reflect.Field.get(Native Method)
W/System.err: at com.kongzue.dialog.v3.MessageDialog.showEvent(MessageDialog.java:630)
问个问题,是compileSdkVersion == 30 才会报错
还是,android 11 的手机都会报错?
----------------更新--------------------
奇怪,我用
compileSdkVersion = 30
minSdkVersion = 21
targetSdkVersion = 30
这个配置是去编译,然后跑在android 11的模拟器上,并没有崩溃
想问下用的是AndroidX版本么?目前我这边的项目也在用但没遇到这个问题

我用的androidX版本但没有崩溃,等我的小米9更新android11后我再测试,但是考虑到android越来越严厉的策略,感觉确实应该减少反射的使用
我也存在这个问题

并不是崩溃,而是引用历史缓存的dailog由于拿不到导致dialog显示不出来,你可以做个简单的测试,在你测试的demo开启messagedialog,然后点击dialog关闭后跳转到其他app,然后在onresume将该dialog带出来,有时候就会带不出来,带不出来的时候就会有这个错误提示
MessageDialog不存在反射

我引用的版本不对嘛?我这边看代码是:630行,而且AlertDialog和androidx无关,这个属于android自身的
Field mAlert = AlertDialog.class.getDeclaredField("mAlert");
mAlert.setAccessible(true);
Object mAlertController = mAlert.get(dialog);

刚刚查了下,这段代码是用于设置AlertDialog的按钮文字样式的,因为Google并没有公开的设置方法不得不这么做。因历史原因,DialogV3框架依然是基于DialogFragment进行的实现,现在我更推荐更新到DialogX这个库( https://github.com/kongzue/DialogX )它的Material主题Dialog是纯粹自己做的实现,不存在这些问题。
你好,我在sdk30也遇到了这个问题
