I don't have enough reputation so i can't comment your question, why don't you use a recyclerview with a gridLayoutManager? You can see a basic example here .

After that you can implement your recyclerview adapter this way:

public class StudentsAdapter extends RecyclerView.Adapter<StudentsAdapter.ViewHolder> {

private final OnStudentItemClickListener mListener;
private Context mContext;
private List<Student> mStudents;

public StudentsAdapter(Context context, List<Student> items, OnStudentItemClickListener listener) {
    mContext = context;
    mStudents =items;
    mListener = listener;
}

@Override
public ViewHolder onCreateViewHolder(ViewGroup parent, int viewType) {
    View view = LayoutInflater.from(parent.getContext())
            .inflate(R.layout.list_item_student, parent, false);
    return new ViewHolder(view);
}

@Override
public void onBindViewHolder(final ViewHolder holder, int position) {
    Student student = mStudents.get(position);

    holder.mTextName.setText(student.getName());
    holder.mTextPrice.setText(student.getID());

    if (student.getImage() != null && student.getImage().length > 0) {
        Glide.with(context)
                .load(student.getImage())
                .into(holder.imageView);
    } else {
        holder.imageView.setImageBitmap(null);
    }
}

@Override
public int getItemCount() {
    return mStudents.size();
}


public interface OnStudentItemClickListener {
    void onStudentItemClick(Student student);
    void onStudentButtonClick(Student student);
}

public class ViewHolder extends RecyclerView.ViewHolder
        implements View.OnClickListener {
    TextView mTextName;
    TextView mTextPrice;
    CircleImageView mImageView;
    Button mDit;

    public ViewHolder(View view) {
        super(view);

        mTextName = (TextView) view.findViewById(R.id.txtName);
        mTextPrice = (TextView) view.findViewById(R.id.studentid);
        mImageView = (CircleImageView) view.findViewById(R.id.imgFood);
        mDit = (Button) view.findViewById(R.id.editit);
        mDit.setOnClickListener(view1 -> {
            if (null != mListener) {
                mListener.onStudentButtonClick(mStudents.get(getAdapterPosition()));
            }
        });
        itemView.setOnClickListener(this);
    }

    @Override
    public void onClick(View view) {
        if (null != mListener) {
            mListener.onStudentItemClick(mStudents.get(getAdapterPosition()));
        }
    }
}

}

Change you XML, i have tested below xml its works fine with GridView

<android.support.v7.widget.CardView 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="wrap_content"
    android:foreground="?android:attr/selectableItemBackground"
    android:orientation="horizontal"
    app:cardCornerRadius="5dp"
    app:cardElevation="3dp"
    app:cardPreventCornerOverlap="false"
    app:cardUseCompatPadding="true">

    <LinearLayout
        android:layout_width="match_parent"
        android:layout_height="wrap_content"
        android:focusable="false"
        android:orientation="horizontal">


        <com.mikhaellopez.circularimageview.CircularImageView
            android:id="@+id/imgFood"
            android:layout_width="80dp"
            android:layout_height="80dp"
            android:layout_margin="10dp"
            app:civ_border_color="#ffffff"
            app:civ_border_width="2dp"
            app:civ_shadow="true"
            app:civ_shadow_color="#000000"
            app:civ_shadow_radius="10" />


        <LinearLayout

            android:layout_weight="1"
            android:gravity="center_horizontal|center_vertical"
            android:orientation="vertical">

            <TextView
                android:id="@+id/txtName"

                android:textAppearance="?android:attr/textAppearanceLarge"
                android:textSize="16sp" />

            <LinearLayout
                android:layout_width="match_parent"
                android:layout_height="wrap_content"
                android:orientation="horizontal">

                <TextView
                    android:id="@+id/currentid"

                    android:text="Current ID : "
                    android:visibility="visible" />

                <TextView
                    android:id="@+id/studentid"
                    android:layout_width="wrap_content"
                    android:layout_height="wrap_content"
                    android:layout_below="@+id/txtName"
                    android:layout_marginEnd="30dp"
                    android:layout_marginRight="30dp"
                    android:layout_toRightOf="@+id/currentid"

                android:layout_gravity="end"
                android:background="@android:drawable/btn_dialog"
                android:focusable="false" />


        </LinearLayout>

    </LinearLayout>


</android.support.v7.widget.CardView>

Your Grid View XML will be Like this.

<GridView
        android:id="@+id/grid"
        android:layout_width="match_parent"
        android:layout_height="match_parent"
        android:focusable="true">

    </GridView>
