Android 在一个选项卡中替换片段
我有两个标签。在其中一个选项卡中,有一个片段(比如fragment1),带有项目的网格视图。如果用户单击网格项,则需要显示新片段(比如fragment2),将旧片段添加到后堆栈中。但我在替换碎片上绊倒了。单击后,相同的片段1再次出现 activity_home.xml:Android 在一个选项卡中替换片段,android,android-fragments,android-tabs,Android,Android Fragments,Android Tabs,我有两个标签。在其中一个选项卡中,有一个片段(比如fragment1),带有项目的网格视图。如果用户单击网格项,则需要显示新片段(比如fragment2),将旧片段添加到后堆栈中。但我在替换碎片上绊倒了。单击后,相同的片段1再次出现 activity_home.xml: <?xml version="1.0" encoding="utf-8"?> <android.support.design.widget.CoordinatorLayout xmlns:android="ht

CategoriesGridDataAdapter.class:
CategoriesItemsRowHolder.view.setOnClickListener(new View.OnClickListener() {
@Override
public void onClick(View view) {
Fragment newFragment = SingleCategoryFragment.newInstance(category);
FragmentTransaction transaction = ((Activity) mContext).getFragmentManager().beginTransaction();
transaction.replace(R.id.categories_recycler_view_layout, newFragment ); // give your fragment container id in first parameter
transaction.addToBackStack(null); // if written, this transaction will be added to backstack
transaction.commit();
}
});
我做错了什么?我如何纠正这个问题
CategoriesItemsRowHolder.view.setOnClickListener(new View.OnClickListener() {
@Override
public void onClick(View view) {
Fragment newFragment = SingleCategoryFragment.newInstance(category);
FragmentTransaction transaction = ((Activity) mContext).getFragmentManager().beginTransaction();
transaction.replace(R.id.categories_recycler_view_layout, newFragment ); // give your fragment container id in first parameter
transaction.addToBackStack(null); // if written, this transaction will be added to backstack
transaction.commit();
}
});
