问题描述
我在我的应用程序中使用v7支持AppCompatDialogFragment
I am using v7 support AppCompatDialogFragment in my app
import android.support.v7.app.AppCompatDialogFragment;
public class LoginDialogFragment extends AppCompatDialogFragment {
}
在整个应用中，我正在使用默认的Fragment和FragmentManager和否 android.support.v4.app.Fragment或adroid.support.v4.app.FragmentManager
Throughout the app I am using default Fragment and FragmentManager and NOT android.support.v4.app.Fragment or adroid.support.v4.app.FragmentManager
import android.app.Fragment;
import android.app.FragmentManager;
现在的问题是我想通过调用方法
Now the problem is I want to show the dialog from an Activity by calling the method
public void show(@NotNull android.support.v4.app.FragmentManager manager,
java.lang.String tag)
不接受 android.app.FragmentManager作为参数.
所以我不能打电话
LoginDialogFragment loginDialogFragment = new LoginDialogFragment();
loginDialogFragment.show(getFragmentManager(), "tag");
现在如何显示对话?
推荐答案
您不能在 AppCompatDialogFragment .实际上，如果您仔细检查AppCompatDialogFragment的导入，您会发现它来自支持库.您必须使用getSupportFragmentManager()而不是getFragmentManager().喜欢
You can't use the native Fragment support with AppCompatDialogFragment. In fact, if you check closer the import of AppCompatDialogFragment, you will find out that it comes from the support library. You have to use getSupportFragmentManager() instead of getFragmentManager(). Like
loginDialogFragment.show(getSupportFragmentManager(), "tag");
AppCompat *中的所有内容都来自支持库
everything from AppCompat* is from the support library
