问题描述
我在一个片段内创建了一个ListView，它具有一个搜索过滤器，问题是XML布局在android studio中显示良好，但是在模拟器或手机中运行时，其显示方式却有所不同(我对齐时显示不正确)，当我单击SearchView时，它也会在选项卡导航下.谁能告诉我如何解决这个问题?
I have a ListView created inside a fragment, and it has a search filter, the problem is XML layout showing fine in android studio but when running in the emulator or phone it's showing differently (not properly as I aligned) and also when I click the SearchView it goes under the tab navigation. Can anyone tell how to fix this?
这是片段:

import java.util.List;
public class Individuals extends android.support.v4.app.ListFragment
implements FindCallback<ParseObject> {
private List<ParseObject> mOrganization = new ArrayList<ParseObject>();
SearchView sv;
IndividualsAdaptor adaptor;
@Override
public View onCreateView(LayoutInflater inflater, ViewGroup container, Bundle savedInstanceState) {
return inflater.inflate(R.layout.individuals, container, false);
}
@Override
public void onViewCreated(View view, Bundle b) {
super.onViewCreated(view, b);
sv = (SearchView) view.findViewById(R.id.ser1);
adaptor = new IndividualsAdaptor(getActivity(), mOrganization);
setListAdapter(adaptor);
ParseQuery.getQuery("_User").findInBackground(this);
sv.setOnQueryTextListener(new SearchView.OnQueryTextListener() {
@Override
public boolean onQueryTextSubmit(String text) {
return false;
}
@Override
public boolean onQueryTextChange(String text) {
adaptor.getFilter().filter(text);
return true;
}
});
}
@Override
public void done(List<ParseObject> scoreList, ParseException e) {
if (e == null) {
Log.d("score", "Retrieved " + scoreList.size() + " _User");
mOrganization.clear();
mOrganization.addAll(scoreList);
((IndividualsAdaptor) getListAdapter()).updateBackupList(mOrganization);
((IndividualsAdaptor) getListAdapter()).notifyDataSetChanged();
} else {
Log.d("score", "Error: " + e.getMessage());
}
}
}

推荐答案
尝试您的ListView时出现错误(我认为它是personals.xml)，例如TextView android:id ="@ id/android:empty"具有android:layout_below ="@ + id/button3"属性，但在您的布局中找不到button3.
I get error when trying your ListView (I think that it is individuals.xml), e.g. TextView android:id="@id/android:empty" has an attribute android:layout_below="@+id/button3" but I can't find button3 in your layout.
这可能是您想要的布局，personal.xml:
This may be the layout that you want, individuals.xml:
<RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android"
xmlns:app="http://schemas.android.com/apk/res-auto"
android:layout_width="match_parent"
android:layout_height="match_parent" >
<ImageView
android:layout_width="wrap_content"
android:layout_height="wrap_content"
app:srcCompat="@drawable/individuals_img"
android:src="@drawable/individuals_img"
android:id="@+id/imageView3"
android:layout_alignParentRight="true"
android:layout_alignParentEnd="true"/>
<SearchView
android:id="@+id/ser1"
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:queryHint="Search.."
android:background="@android:color/holo_red_dark"
android:layout_alignParentTop="true"
android:layout_alignParentLeft="true"
android:layout_alignParentStart="true"
android:layout_toLeftOf="@+id/imageView3"
android:layout_toStartOf="@+id/imageView3" >
</SearchView>
<TextView android:id="@id/android:empty"
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:text="No data"
android:layout_alignParentLeft="true"
android:layout_alignParentStart="true"
android:layout_below="@+id/ser1" />
<ListView android:id="@id/android:list"
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:layout_below="@+id/ser1" />
</RelativeLayout>
如果这不是您想要的内容，请同时在Android Studio布局编辑器中显示您的布局.希望对您有所帮助:)
If this is not what you are looking for, please also show what your layout looks like in Android Studio layout editor. Hope it help :)
