Question

我有一个全屏网格布局，包含8行7 ImageView。我需要所有行都居中，行之间没有空格（现在，我已经上传了图像）。空格只能在顶部和底部。我已经尝试在Internet上找到一种解决方案，但没有找到。

XML：

}}

我尝试将所有ImageViews的高度设置为与宽度相同的解决方案，但是我的代码无法正常工作

<?xml version="1.0" encoding="utf-8"?>
<RelativeLayout 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=".MainActivity">

    <GridLayout
        android:id="@+id/gameGrid"
        android:layout_width="match_parent"
        android:layout_height="match_parent"
        android:layout_centerVertical="true"
        android:rowCount="8"
        android:columnCount="7"
        >
        <!-- ROW 1-1 -->
        <ImageView
            android:layout_width="0dp"
            android:layout_height="0dp"
            android:id="@+id/cellR1-1"
            android:layout_rowWeight="1"
            android:layout_columnWeight="1"
            app:srcCompat="@drawable/dl"
            />
        <!-- ROW 1-2 -->
        <ImageView
            android:layout_width="0dp"
            android:layout_height="0dp"
            android:id="@+id/cellR1-2"
            android:layout_rowWeight="1"
            android:layout_columnWeight="1"
            app:srcCompat="@drawable/dl"
            />
        <!-- ROW ... -->
    </GridLayout>
</RelativeLayout>

Answer 1

使用RecyclerView代替GridLayout可能对您有所帮助

RecyclerView.LayoutManager recyclerViewLayoutManager = new GridLayoutManager(getApplicationContext(), 7); // 7 means how many column you want you can change according to your requirement.
recyclerView.setLayoutManager(recyclerViewLayoutManager);

Answer 2

尝试将RecyclerView与GridLayoutManager一起使用，如下所示：

GridLayoutManager layoutManager = new GridLayoutManager(getContext(), 7);
            YourAdapter adapter = new YourAdapter();
            recyclerView.setLayoutManager(layoutManager);
            recyclerView.setAdapter(adapter);

            int spacing = (int) TypedValue.applyDimension(TypedValue.COMPLEX_UNIT_DIP, 16,
                    Objects.requireNonNull(getContext()).getResources().getDisplayMetrics());
            recyclerView.addItemDecoration(new RecyclerView.ItemDecoration() {
                @Override
                public void getItemOffsets(@NotNull Rect outRect, @NotNull View view, @NotNull RecyclerView parent, @NotNull RecyclerView.State state) {

                    if (parent.getChildAdapterPosition(view) == Objects.requireNonNull(parent.getAdapter()).getItemCount() - 1) {
                        outRect.bottom = spacing;
                    }
                    if (parent.getChildAdapterPosition(view) == 0) {
                        outRect.top = spacing;
                    }
                }
            });

其他解决方案是： 只需将填充添加到RecyclerView的顶部和底部，然后将clipToPadding属性设置为false，就不必在顶部和底部都添加填充。

<android.support.v7.widget.RecyclerView
    android:layout_width="match_parent"
    android:layout_height="match_parent"
    android:clipToPadding="false"
    android:paddingTop="8dp"
    android:paddingBottom="8dp" />

如何在GridLayout中居中放置ImageView？
