第二次冲刺

在第二个冲刺完成了主界面的设计，包括导航轮播图，我的界面的完善，干的活有点少。

源代码：

我的界面：

package com.example.myapplication;

import android.os.Bundle;
import android.view.LayoutInflater;
import android.view.View;
import android.view.ViewGroup;
import android.widget.Button;

import androidx.annotation.NonNull;
import androidx.annotation.Nullable;
import androidx.fragment.app.Fragment;
import androidx.lifecycle.ViewModelProvider;
import androidx.navigation.NavController;
import androidx.navigation.Navigation;

public class ThirdFragment extends Fragment {

    private ThirdViewModel mViewModel;
    private Button personaldata;
    private Button mycollection;
    private Button myachievement;
    private Button about;

    public static ThirdFragment newInstance() {
        return new ThirdFragment();
    }

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

        return inflater.inflate(R.layout.third_fragment, container, false);
    }

    @Override
    public void onViewCreated(@NonNull View view, @Nullable Bundle savedInstanceState) {
        super.onViewCreated(view, savedInstanceState);
        mViewModel = new ViewModelProvider(this).get(ThirdViewModel.class);

        personaldata = view.findViewById(R.id.personaldata);
        mycollection = view.findViewById(R.id.mycollection);
        myachievement = view.findViewById(R.id.myachievement1);
        about = view.findViewById(R.id.about);

        personaldata.setOnClickListener(new View.OnClickListener() {
            @Override
            public void onClick(View view) {
                NavController navController= Navigation.findNavController(view);
                navController.navigate(R.id.action_thirdFragment_to_personalshowFragment);

            }
        });

        mycollection.setOnClickListener(new View.OnClickListener() {
            @Override
            public void onClick(View view) {

            }
        });

        myachievement.setOnClickListener(new View.OnClickListener() {
            @Override
            public void onClick(View view) {

            }
        });

        about.setOnClickListener(new View.OnClickListener() {
            @Override
            public void onClick(View view) {

            }
        });
    }
}
