Android Dialog 的一些使用和优化心得（DialogFragment的使用和优化）

import com.android.angola.wenna.R;

public class ExitFragment extends DialogFragment

{

private View rootView;

private TextView tv_yes;

private TextView tv_no;

private OnYesClickListener onYesClickListener;

private onNoClickListener onNoClickListener;

public void setOnNoClickListener(ExitFragment.onNoClickListener onNoClickListener) {

this.onNoClickListener = onNoClickListener;

}

public void setOnYesClickListener(OnYesClickListener onYesClickListener) {

this.onYesClickListener = onYesClickListener;

}

@Nullable

@Override

public View onCreateView(@NonNull LayoutInflater inflater, @Nullable ViewGroup container, @Nullable Bundle savedInstanceState) {

if (rootView == null)

{

rootView = inflater.inflate(R.layout.fragment_exit,container,false);

this.tv_yes = rootView.findViewById(R.id.tv_dialog_yes);

this.tv_no = rootView.findViewById(R.id.tv_dialog_no);

}

return rootView;

}

public interface OnYesClickListener{

void onYesClickener();

}

public interface onNoClickListener{

void onNoClicked();

}

@Override

public void onResume() {

super.onResume();

this.tv_yes.setOnClickListener(v -> onYesClicked());

this.tv_no.setOnClickListener(v -> onNoClicked());

}

private void onNoClicked() {

if (onNoClickListener != null)

{

onNoClickListener.onNoClicked();

}

}

private void onYesClicked() {

if (onYesClickListener != null)

{

onYesClickListener.onYesClickener();

}

}

}
