处理网格视图中的项目可见性[重复]

Question

我正在从 firebase firestore 集合中检索图像到网格图像视图中。但我只想显示具有当前用户 ID 的图像，并通过将可见性设置为消失来隐藏其余图像，但这会通过在图像之间留下空白（白色）空间来混淆视图。

这是我试图在我的适配器中隐藏视图

if (convertView == null)
        convertView = inflater.inflate(R.layout.image_grid_view, null);

    ImageView postImage =  convertView.findViewById(R.id.my_store_posts);

    Posts e = new Posts();
    e = postList.get(position);

    //final String title = e.getTitle();
    final String image = e.getImage_url();

    String uid = FirebaseAuth.getInstance().getCurrentUser().getUid();

    if (e.getUser_id().equals(uid)) {

        Picasso.with(context).load(image).into(postImage);
    }else {
        postImage.setVisibility(View.GONE);
    }

    return convertView;
}
}

这是我的布局

<?xml version="1.0" encoding="utf-8"?>
<android.support.constraint.ConstraintLayout xmlns:android="http://schemas.android.com/apk/res/android"
xmlns:app="http://schemas.android.com/apk/res-auto"
xmlns:tools="http://schemas.android.com/tools"
android:layout_width="match_parent"
android:layout_height="match_parent"
tools:context=".MyStoreActivity">

<GridView
    android:id="@+id/my_store_grid"
    android:layout_width="0dp"
    android:layout_height="0dp"
    android:layout_marginTop="8dp"
    android:numColumns="3"
    app:layout_constraintBottom_toBottomOf="parent"
    app:layout_constraintEnd_toEndOf="parent"
    app:layout_constraintStart_toStartOf="parent"
    app:layout_constraintTop_toBottomOf="parent"
     />

适配器布局

<?xml version="1.0" encoding="utf-8"?>
<android.support.constraint.ConstraintLayout
xmlns:android="http://schemas.android.com/apk/res/android"
xmlns:app="http://schemas.android.com/apk/res-auto"
xmlns:tools="http://schemas.android.com/tools"
android:layout_width="match_parent"
android:layout_height="match_parent">

<ImageView
    android:id="@+id/my_store_posts"
    android:layout_width="150dp"
    android:layout_height="150dp"
    android:scaleType="centerCrop"
    app:layout_constraintStart_toStartOf="parent"
    app:layout_constraintTop_toTopOf="parent"
    app:srcCompat="@drawable/default_avatar" />

尝试隐藏整个视图：

if (e.getUser_id().equals(uid)) {

    convertView.setVisibility(View.VISIBLE);
    Picasso.with(context).load(image).into(postImage);

}else {
    convertView.setVisibility(View.GONE);
}
