问题：当点击viewpager中的一个fragment时，进入另一个不相关的fragment，按返回键返回原来的fragment？

回答：判断初始化动画位置

例子：

传值

@Overridepublic void onItemClick(AdapterView<?> parent, View view, int position,long id) {// 获取商品位置Themes themes = (Themes) parent.getItemAtPosition(position);// 创建GoodsInfoFragment对象ThemeFragment fragment = new ThemeFragment();// 传值Bundle bundle = new Bundle();bundle.putString("title", themes.getTitle());bundle.putString("content", themes.getContent());bundle.putInt("tag", 1);fragment.setArguments(bundle);Fragment yfragment = getParentFragment().getFragmentManager().findFragmentByTag("theme");// 判断是否为nullif (yfragment != null) {// 移除getParentFragment().getFragmentManager().beginTransaction().remove(yfragment).commit();}// 添加getParentFragment().getFragmentManager().beginTransaction().setTransition(FragmentTransaction.TRANSIT_FRAGMENT_FADE).add(R.id.main_content, fragment, "theme").commit();// 显示MainActivity activity = (MainActivity) getActivity();activity.replaceMain("theme");}

接受值

iv_return.setOnClickListener(new OnClickListener() {@Overridepublic void onClick(View v) {int tag = getArguments().getInt("tag");// 创建GoodsInfoFragment对象HomeFragment fragment = new HomeFragment(tag);Fragment yfragment = getFragmentManager().findFragmentByTag("home");// 判断是否为nullif (yfragment != null) {// 移除getFragmentManager().beginTransaction().remove(yfragment).commit();}// 添加getFragmentManager().beginTransaction().setTransition(FragmentTransaction.TRANSIT_FRAGMENT_FADE).add(R.id.main_content, fragment, "home").commit();// 显示mainActivity.replaceMain("home");}});

重写方法

private int id;public HomeFragment() {}public HomeFragment(int id) {this.id = id;}

判断初始化

//判断 初始化动画位置if (this.id == 1) {animation = new TranslateAnimation(offset, position_one, 0, 0);} else {animation = new TranslateAnimation(position_one, offset, 0, 0);}currIndex = this.id;mPager.setCurrentItem(currIndex);
