我正在尝试将DialogFragment创建为
public class PlaceFragment extends DialogFragment {
public PlaceFragment() {
}
public static PlaceFragment newInstance() {
PlaceFragment placeFragment = new PlaceFragment();
Bundle args = new Bundle();
args.putDouble("Latitude", 12.3456);
placeFragment.setArguments(args);
return placeFragment;
}
@Override
public View onCreateView(LayoutInflater inflater, ViewGroup container,
Bundle savedInstanceState) {
View v = inflater.inflate(R.layout.fragment_place, container, false);
AlertDialog.Builder placePicker = new AlertDialog.Builder(getContext());
placePicker.setView(R.layout.fragment_place)
.setTitle("Enter Latitude and Longitude")
.setPositiveButton("Ok", null);
// return inflater.inflate(R.layout.fragment_place, container);
return v;
}
}
应称为：
case R.id.action_geolocate:
FragmentManager fm = getSupportFragmentManager();
PlaceFragment placeFragment = PlaceFragment.newInstance();
placeFragment.show(fm, "");
return true;
但是，正如您所看到的，这是行不通的，因为这显然只显示了已夸大的布局。但是我试图用两行EditText的Ok和Dissmiss按钮来打开对话框。
如果我使用完全手动的方式，那么我将获得editText，但不知道如何使用OkButton获得那些值，例如：
@Override
public View onCreateView(LayoutInflater inflater, ViewGroup container,
Bundle savedInstanceState) {
return inflater.inflate(R.layout.fragment_place, container);
}
您可以
希望这会有所帮助。
我认为您应该替换此
我希望为您工作。
如果我理解正确，类似这样的方法应该起作用：
public class DialogEnterExit extends DialogFragment {
public interface EnterExitDialogListener {
void onFinishEditDialog(String event, String place, Location location);
}
EnterExitDialogListener mListener;
private static final String TAG = DialogEnterExit.class.getSimpleName();
AppCompatDialog mDialog;
String mPlace;
Location mLocation;
public static DialogEnterExit newInstance(String place, Location location) {
DialogEnterExit f = new DialogEnterExit();
// Supply num input as an argument.
Bundle args = new Bundle();
args.putString("PLACE", place);
args.putParcelable("LOCATION", location);
f.setArguments(args);
return f;
}
@Override
public void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
mPlace = getArguments().getString("PLACE");
mLocation = getArguments().getParcelable("LOCATION");
}
@NonNull
@Override
public Dialog onCreateDialog(@Nullable Bundle savedInstanceState) {
AlertDialog.Builder builder = new AlertDialog.Builder(getActivity());
LayoutInflater layoutInflater = getActivity().getLayoutInflater();
View view = layoutInflater.inflate(R.layout.layout_enter_exit_dialog,null);
final RadioButton enter = view.findViewById(R.id.radio_enter);
final RadioButton exit = view.findViewById(R.id.radio_exit);
TextView place = view.findViewById(R.id.place_picked);
place.setText(mPlace);
enter.setOnClickListener(new View.OnClickListener() {
@Override
public void onClick(View v) {
if (mListener != null) {
mListener.onFinishEditDialog(getString(R.string.dialog_transition_entered), mPlace,
mLocation);
}
mDialog.dismiss();
}
});
exit.setOnClickListener(new View.OnClickListener() {
@Override
public void onClick(View v) {
if (mListener != null) {
mListener.onFinishEditDialog(getString(R.string.dialog_transition_exited), mPlace,
mLocation);
}
mDialog.dismiss();
}
});
builder
.setView(view)
.setTitle(getString(R.string.dialog_title_event))
.setCancelable(true);
mDialog = builder.create();
return mDialog;
}
@Override
public void onAttach(@NonNull Context context) {
super.onAttach(context);
// Verify that the host activity implements the callback interface
try {
// Instantiate the EditNameDialogListener so we can send events to the
host
mListener = (EnterExitDialogListener) context;
} catch (ClassCastException e) {
// The activity doesn't implement the interface, throw exception
throw new ClassCastException(context.toString()
+ " must implement EnterExitDialogListener" );
}
}
@Override
public void onDetach() {
super.onDetach();
mListener = null;
}
}
