如何将我的孩子片段充气到活动中?

我想用view pager实现SlidingTabs。我按照指定的步骤in this link进行了操作。我的情况只有一个区别。我使用片段而不是活动。所以在这种情况下,我想在用户按下标签时给孩子片段充气。

这是我尝试这样做的方法:

//I am using navigation drawer in my activity and when user press one item it create a fragment which I want to show many child fragments using tabs
@Override
public void onItemClick(int position) {

    switch (position){
        case 3 :
            mFragmentManager = getSupportFragmentManager();
            mFragment = new MainFragment().newInstance(mHelpLiveo.get(position).getName());

            if (mFragment != null){
                mFragmentManager.beginTransaction().replace(R.id.container, mFragment).commit();
            }
            break;
    }
}

我的MainFragment.java中的onCreateView函数:

@Override
public View onCreateView(LayoutInflater inflater, ViewGroup container,
                         Bundle savedInstanceState) {
    // Inflate the layout for this fragment
    View rootView = inflater.inflate(R.layout.group_tabs, container, false);

    // Creating The ViewPagerAdapter and Passing Fragment Manager, Titles fot the Tabs and Number Of Tabs.

    //EDİT 3 :
    adapter =  new ViewPagerAdapter(this.getChildFragmentManager(),Titles,Numboftabs);

    // Assigning ViewPager View and setting the adapter
    pager = (ViewPager) rootView.findViewById(R.id.private_public_pager);
    pager.setAdapter(adapter);

    // Assiging the Sliding Tab Layout View
    tabs = (SlidingTabLayout) rootView.findViewById(R.id.tabs);
    tabs.setDistributeEvenly(true); // To make the Tabs Fixed set this true, This makes the tabs Space Evenly in Available width

    // Setting Custom Color for the Scroll bar indicator of the Tab View
    tabs.setCustomTabColorizer(new SlidingTabLayout.TabColorizer() {
        @Override
        public int getIndicatorColor(int position) {
            return getResources().getColor(R.color.blue_grey_900);
        }
    });

    // Setting the ViewPager For the SlidingTabsLayout
    tabs.setViewPager(pager);
    return rootView;
}

在我的ViewPagerAdapter类中:

//This method return the fragment for the every position in the View Pager
@Override
public Fragment getItem(int position) {

    if(position == 0) // if the position is 0 we are returning the First tab
    {
        Tab1 tab1 = new Tab1();
        return tab1;
    }
    else             // As we are having 2 tabs if the position is now 0 it must be 1 so we are returning second tab
    {
        Tab2 tab2 = new Tab2();
        return tab2;
    }

}

其他任何内容与the link I provided above相同。

</LinearLayout>

在mainfragment.xml文件中只出现SlidingTabLayout我无法看到Vİew寻呼机。

一些屏幕来解释我的申请。

my main activity with navigation drawer. when user press one item my main fragment is created 我的主要活动与导航抽屉。当用户按下一个项目时,我的主片段被创建

enter image description here 我的主要片段显示标签。但无法看到查看寻呼机。

答案 0 :(得分:1)

在mainfragment.xml布局中,LinearLayout方向设置为水平,因此项目水平位于同一行。 SlidingTabLayout的宽度是match_parent,因此ViewPager被压缩到右边,宽度为0.只需将方向更改为“vertical”

<LinearLayout
xmlns:android="http://schemas.android.com/apk/res/android"
xmlns:tools="http://schemas.android.com/tools"
android:orientation="vertical"
android:layout_width="fill_parent"
android:layout_height="fill_parent"
tools:context="com.melomg.example.ui.MainFragment">

...

</LinearLayout>
