如何修复`类型不匹配:无法从android.app.FragmentManager转换为android.support.v4.app.FragmentManager`错误在android？

Question

我收到以下错误

Type mismatch: cannot convert from android.app.FragmentManager to android.support.v4.app.FragmentManager

对于以下行

FragmentManager frgManager = getFragmentManager();
frgManager.beginTransaction().replace(R.id.content_frame, fragment).commit()

我班上有以下导入

 import android.support.v4.app.Fragment;
 import android.support.v4.app.FragmentManager;
 import android.support.v4.app.FragmentTransaction;

如何修复错误？

Answer 1

替换getFragmentManager()为getSupportFragmentManager(),并确保您的类是其子类FragmentActivity.
