android Cannot resolve method 'getTabHost' in 'Tab'

这个问题可能是因为你在使用TabHost时没有正确地引用它。请确保你已经在你的布局文件中添加了TabHost，并且在你的Activity中正确地绑定了它。你可以尝试使用以下代码来获取TabHost：

TabHost tabHost = (TabHost) findViewById(android.R.id.tabhost);

如果你的布局文件中定义的TabHost的ID为"tabhost"，则可以使用以下代码：

TabHost tabHost = (TabHost) findViewById(R.id.tabhost);

如果以上方法仍然无法解决你的问题，请提供更多的上下文信息，以便我更好地帮助你解决这个问题。

问题:android cannot resolve method
回答:根据提供的代码和引用内容，问题出现在跳转部分的代码中。错误提示是"Cannot resolve method 'putExtra(android.os.Bundle)'"，这意味着在Intent的putExtra方法中传入的参数类型不正确。在你的代码中，你使用了putExtra方法来传递一个Bundle对象，但是putExtra方法的参数应该是一个String类型的键和对应的值。所以正确的写法应该是putExtras方法，而不是putExtra方法。所以你需要将代码修改为：
startActivity(new Intent(context, JumpWepPageActivity.class).putExtras(mBundle));
这样就能正确地传递Bundle对象了。希望这能解决你的问题。

Android Cannot resolve method 'checkSelfPermission' in 'ContextCompat'

This error occurs when you try to use the `checkSelfPermission` method from the `ContextCompat` class in an Android project and Android Studio is unable to resolve the method.

To resolve this error, you need to make sure that you have the latest version of the `support-v4` library in your project. You can do this by adding the following line to your app's build.gradle file:

implementation 'com.android.support:support-v4:28.0.0'

Once you have added this line, sync your project and try using the `checkSelfPermission` method again. It should now resolve correctly.
