Android-Navigation(导航)切换Fragment&动画(Animations)

这种方式只能给自己设置,只适合静态传递

  @Override
    public View onCreateView(LayoutInflater inflater, ViewGroup container,
                             Bundle savedInstanceState) {
        // Inflate the layout for this fragment
        View viewFragment = inflater.inflate(R.layout.fragment_home, container, false);
        Button but3 = viewFragment.findViewById(R.id.button3);

        but3.setonClickListener(new View.onClickListener() {
            @Override
            public void onClick(View v) {
                //getView相当于 inflater.inflate(R.layout.fragment_home, container, false)
                EditText editText = getView().findViewById(R.id.editText01);
                if (editText.getText().toString().isEmpty()) {
                    return;
                }
                //传递值
                Bundle bundle = new Bundle();
                bundle.putString("my_name",editText.getText().toString());

                NavController navController = Navigation.findNavController(v);
                //从home跳转到detail
                navController.navigate(R.id.action_homeFragment_to_detailFragment,bundle);

            }
        });
        return viewFragment;
    }

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

        //获取对应的fragment
        View viewFragment = inflater.inflate(R.layout.fragment_detail, container, false);
        //获取静态中参数
        String name = getArguments().getString("name");
        //获取从home fragment 传递过来的参数
        String myName = getArguments().getString("my_name");
        //设置值
        TextView text2 = viewFragment.findViewById(R.id.textView2);
        text2.setText(myName);

        Button but = viewFragment.findViewById(R.id.button);
        but.setonClickListener(new View.onClickListener() {
            @Override
            public void onClick(View v) {
                NavController navController = Navigation.findNavController(v);
                //从detail跳转到home
                navController.navigate(R.id.action_detailFragment_to_homeFragment);

            }
        });
        return viewFragment;
    }

package com.example.navigationdemo;

import androidx.appcompat.app.AppCompatActivity;
import androidx.navigation.NavController;
import androidx.navigation.Navigation;
import androidx.navigation.ui.NavigationUI;

import android.os.Bundle;

public class MainActivity extends AppCompatActivity {
    NavController navController;

    @Override
    protected void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.activity_main);
        navController = Navigation.findNavController(this, R.id.fragment);
        //actionBar 左上角后退键
        NavigationUI.setupActionBarWithNavController(this, navController);

    }

    //    重写 onSupportNavigateUp 方法
    @Override
    public boolean onSupportNavigateUp() {
        return navController.navigateUp();

    }
}
