Question

我使用updateCount但在其下面有EditText。在ListView中键入文本输入后按完成或单击返回以隐藏键盘。然后键盘后面的EditText部分消失了，取而代之的是白色区域（清除），为什么？

注意：此片段位于tablayout和viewpager下，包含编辑文本和列表视图的片段从主片段启动这是主要片段

ListView

}

这是xml的主片段

    public class FriendsFragment extends Fragment {

public FriendsFragment() {
    // Required empty public constructor
}
private FragmentActivity myContext;

private Toolbar toolbar;
private TabLayout tabLayout;
private ViewPager viewPager;

@Override
public void onCreate(Bundle savedInstanceState) {
    super.onCreate(savedInstanceState);
}
@Override
public void onAttach(Activity activity) {
    myContext=(FragmentActivity) activity;
    super.onAttach(activity);
}
@Override
public View onCreateView(LayoutInflater inflater, ViewGroup container, Bundle savedInstanceState) {
   View rootview=inflater.inflate(R.layout.friends_fragment, container, false);


    viewPager = (ViewPager) rootview.findViewById(R.id.viewpager);
    setupViewPager(viewPager);

    tabLayout = (TabLayout) rootview.findViewById(R.id.tabs);
    tabLayout.setupWithViewPager(viewPager);

    tabLayout.setupWithViewPager(viewPager);

    tabLayout.setOnTabSelectedListener(
            new TabLayout.ViewPagerOnTabSelectedListener(viewPager) {
                @Override
                public void onTabSelected(TabLayout.Tab tab) {
                    super.onTabSelected(tab);

                    if (tab.getPosition() == 1) {
                        FindFriendsFragment.myfriends_list.invalidate(FindFriendsFragment.myfriends_list.getLeft(), FindFriendsFragment.myfriends_list.getTop(), FindFriendsFragment.myfriends_list.getRight(), FindFriendsFragment.myfriends_list.getBottom());
                        FindFriendsFragment.adapter.notifyDataSetChanged();
                        FindFriendsFragment.myfriends_list.clearFocus();
                        FindFriendsFragment.myfriends_list.postInvalidate();
                    }


                }
            });





    TextView friends = (TextView) rootview.findViewById(R.id.search);
    Typeface Exo_thin = Typeface.createFromAsset(myContext.getAssets(), "fonts/Exo2.0-Thin.otf");
    friends.setTypeface(Exo_thin);
      return rootview;

 }
private void setupViewPager(ViewPager viewPager) {
    ViewPagerAdapter adapter = new ViewPagerAdapter(getChildFragmentManager());
     adapter.addFragment(new MyFriendsFragment(), "My Friends");
    adapter.addFragment(new FindFriendsFragment(), "Find Friends");
     adapter.addFragment(new TwoFragment(), "Friend Requests");
    viewPager.setAdapter(adapter);
}

class ViewPagerAdapter extends FragmentStatePagerAdapter {
    private final List<Fragment> mFragmentList = new ArrayList<>();
    private final List<String> mFragmentTitleList = new ArrayList<>();

    public ViewPagerAdapter(FragmentManager manager) {
        super(manager);
    }

    @Override
    public Fragment getItem(int position) {
        return mFragmentList.get(position);
    }

    @Override
    public int getCount() {
        return mFragmentList.size();
    }

    public void addFragment(Fragment fragment, String title) {
        mFragmentList.add(fragment);

        mFragmentTitleList.add(title);
    }

    @Override
    public CharSequence getPageTitle(int position) {
        return mFragmentTitleList.get(position);
    }
}

包含listview和编辑文本的片段

    <RelativeLayout

android:clickable="true"

>


<android.support.design.widget.AppBarLayout
    android:layout_width="match_parent"
    android:layout_height="wrap_content"
     android:textAllCaps="false"
    android:theme="@style/ThemeOverlay.AppCompat.Dark.ActionBar">
    <RelativeLayout
        android:layout_height="match_parent"
        android:layout_width="match_parent"
        android:orientation="vertical"
        android:id="@+id/rel"
        android:layout_alignParentTop="true"

        android:weightSum="1">

        <TextView
            android:layout_width="match_parent"
            android:layout_height="60dp"
            android:id="@+id/search"
            android:text="Friends"
            android:layout_marginLeft="10dp"
            android:gravity="center_vertical"
            android:textSize="25sp"
             android:textColor="@color/colorVeryDarkBlue"
            />

    </RelativeLayout>


    <android.support.design.widget.TabLayout
        android:id="@+id/tabs"
        android:layout_width="match_parent"
        android:layout_height="wrap_content"
        app:tabTextAppearance="@android:style/TextAppearance.Widget.TabWidget"
        app:tabSelectedTextColor="@color/colorLightGreen"
        app:tabTextColor="@color/colorDarkGreen"
         app:tabMode="scrollable"
         android:background="@color/colorDarkBlue"

        app:tabIndicatorColor="@color/colorDarkBlue"

        app:tabGravity="center"/>

    android:id="@+id/viewpager"
    android:layout_width="match_parent"

相关的xml文件是包含listview和edittext的片段：

    public class FindFriendsFragment extends Fragment {

    public FindFriendsFragment()
    {
        // Required empty public constructor
    }
    ListView myfriends_list;
    FindFriendsAdapter adapter;
    ArrayList<FindFriends> arraylist ;


    @Override
    public void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
    }

    @Override
    public View onCreateView(LayoutInflater inflater, ViewGroup container, Bundle savedInstanceState)
    {
        View rootview= inflater.inflate(R.layout.find_friends_fragment, container, false);

      EditText search=(EditText) rootview.findViewById(R.id.search);

        Typeface Exo_Regular =   

         Typeface.createFromAsset(getActivity().getAssets(), "fonts/Exo2.0-
          Regular.otf");
        search.setTypeface(Exo_Regular);
        arraylist = new ArrayList<FindFriends>();
        arraylist.add(new FindFriends("mina fared", "hello     
            guys",1,"sdsdsdsds",true )) ;

        adapter = new FindFriendsAdapter(getActivity(), arraylist);

        myfriends_list.setAdapter(adapter);
        adapter.notifyDataSetChanged();


        return rootview;
    }

  }

Answer 1

从manifest.xml

搜索您的活动标签

<activity
        android:name=".YourActivity"
        android:label="@string/title_activity"
        ...>
</activity>

然后像那样添加android：configChanges =“keyboard | keyboardHidden”

<activity
        android:name=".YourActivity"
        android:configChanges="keyboard|keyboardHidden"
        android:label="@string/title_activity"
        ...>
</activity>

修改

我发现我的答案不完全正确你可以添加

android:windowSoftInputMode="adjustNothing"

抱歉

在片段实现中，EditText下面的ListView在设置要隐藏的键盘元素（EditText视图）后消失
