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?

This is the fragment:

import android.content.Context;
import android.os.Bundle;
import android.util.Log;
import android.view.LayoutInflater;
import android.view.View;
import android.view.ViewGroup;
import android.widget.ArrayAdapter;
import android.widget.ImageView;
import android.widget.ListView;
import android.widget.SearchView;
import android.widget.Toast;
import com.parse.FindCallback;
import com.parse.ParseException;
import com.parse.ParseFile;
import com.parse.ParseObject;
import com.parse.ParseQuery;
import java.net.URL;
import java.util.ArrayList;
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());
        }
    }
}

This is the adapter:

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.

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>

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 :)
