こんにちは私はダイアログフラグメントを書いていて、getArgumentsとsetArgumentsを使用していくつかのデータを渡そうとしていますが、getArgumentsを使用してデータを取得しているときにNPEを取得します。
public class EditNameDialog extends DialogFragment{
public static EditNameDialog newInstance(int type){
EditNameDialog thedialog=new EditNameDialog();
Bundle bundle=new Bundle();
Log.v("typ",type+"");//-->logs fine here
bundle.putInt("mytype", type);
thedialog.setArguments(bundle);
return thedialog;
}
public Dialog onCreateDialog(Bundle icic){
String ok="Play";
//I get a NPE here in the below line
switch(getArguments().getInt("mytype")){
case 1:
case 2:
ok="Play";
break;
case 3:
ok="Show";
break;
case 4:
ok="Show";
break;
}
//show alert dialog etc etc here
}
}
誰かがこれを見て、私がここで何が欠けているのか教えてもらえますか？
編集：-これは私がdialogfragmentを呼び出す方法です：-
DialogFragment newFragment = EditNameDialog.newInstance(1);
newFragment.show(getSupportFragmentManager(), "mydialog");
