Fragment动画切换效果

1.系统自带的动画切换效果

FragmentTransaction fragmentTransaction = mFragmentManager
                .beginTransaction();

fragmentTransaction.setTransition(int transit)；
// 通过setTransition(int transit)进行设置
// transit参数说明
// 1. FragmentTransaction.TRANSIT_NONE：无动画
// 2. FragmentTransaction.TRANSIT_FRAGMENT_OPEN：标准的打开动画效果
// 3. FragmentTransaction.TRANSIT_FRAGMENT_CLOSE：标准的关闭动画效果

// 标准动画设置好后，在Fragment添加和移除的时候都会有。

2. 自定义动画切换效果

// 采用`FragmentTransavtion`的 `setCustomAnimations（）`进行设置

FragmentTransaction fragmentTransaction = mFragmentManager
                .beginTransaction();

fragmentTransaction.setCustomAnimations(
                R.anim.in_from_right,
                R.anim.out_to_left);

// 此处的自定义动画效果同Activity，此处不再过多描述

public class Main2Activity extends AppCompatActivity implements View.OnClickListener{
    private TextView tv_home,tv_person;
    private FrameLayout fl;
    private FragmentManager mFragmentManager;
    private ItemFragment mItemFragment;
    private HomeFragment mHomeFragment;

    @Override
    protected void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.activity_main2);
        initView();
    }

    private void initView() {
        tv_home=findViewById(R.id.tv_home);
        tv_person=findViewById(R.id.tv_person);
        fl=findViewById(R.id.fl);
        tv_home.setOnClickListener(this);
        tv_person.setOnClickListener(this);
        mFragmentManager = getSupportFragmentManager();
        mHomeFragment=HomeFragment.newInstance();
        mItemFragment=ItemFragment.newInstance();
    }

    @Override
    public void onClick(View v) {
        switch (v.getId()){
            case R.id.tv_home:
                switchPage(mHomeFragment);
                break;
            case R.id.tv_person:
                switchPage(mItemFragment);
                break;
                default:
                    break;
        }
    }

    //切换页面 (自定义fragment切换动画)
    private void switchPage(Fragment fragment) {
        FragmentTransaction fragmentTransaction = mFragmentManager.beginTransaction();
        fragmentTransaction
                .setCustomAnimations(R.anim.right_in,R.anim.left_out)
                .replace(R.id.fl,fragment)
                .commit();

    }
