网格布局（不GridView控件） - 细胞之间的空间网格、控件、布局、细胞

我使用在我的应用程序中显示的ImageView 取值网格布局（支持）。有3列和5行。问题是，这些细胞在它们之间的网格布局自动获得一些空间。我没有设置任何填充或保证金的细胞。请参考下面的图片。所有单元动态添加，这里是我如何添加这些细胞。

I am using GridLayout(support) for displaying ImageViews in my application. There are 3 columns and 5 rows. The problem is that the cells in the GridLayout automatically get some space between them. I am not setting any padding or margin for the cells. Please refer to the image below. All cells are added dynamically and here is how I add these cells.

获取屏幕宽度和高度：

Point size = new Point();
getWindowManager().getDefaultDisplay().getSize(size);
screenWidth = size.x;
screenHeight = size.y;
rowHeight = (int) (screenHeight * 0.2);

添加视图以网格布局：

Adding View to GridLayout:

    GridLayout.LayoutParams params = new GridLayout.LayoutParams(
            getSpec(rowColumn[0]), getSpec(rowColumn[1]));

    params.height = rowHeight;

    if (rowColumn[1].equalsIgnoreCase("col_full")) {
        params.width = (int) (screenWidth);
    } else if (rowColumn[1].equalsIgnoreCase("col_two_part")) {
        params.width = (int) (screenWidth * 0.6);
    } else {
        params.width = (int) (screenWidth * 0.3);
    }

    ImageButton image = (ImageButton) imageHashMap
            .get(reOrderedButtonsListCopy.get(i));
    image.setLayoutParams(params);

    gridLayout.addView(image, params);

XML布局：

XML Layout:

<ScrollView xmlns:android="http://schemas.android.com/apk/res/android"
    xmlns:app="http://schemas.android.com/apk/res/com.xx.xxx"
    android:id="@+id/scrollView1"
    android:layout_width="wrap_content"
    android:layout_height="wrap_content" >

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

        <android.support.v7.widget.GridLayout
            xmlns:app="http://schemas.android.com/apk/res/com.xx.xxx"
            android:id="@+id/gridlayout_main"
            android:layout_width="match_parent"
            android:layout_height="match_parent"
            android:layout_margin="2dp"
            app:columnCount="3"
            app:rowCount="5" >
        </android.support.v7.widget.GridLayout>

    </LinearLayout>

</ScrollView>

当前的结果：

Current result:

红色线显示在单元之间的空间。此外，有关于GridLayout的左侧一些空间。我只给 2DP 为 layout_margin 。任何原因，这个填充出现？

The red lines show the spaces in between the cells. Also, there is some space on the left side of GridLayout. I have only given 2dp as layout_margin. Any reasons why this padding occurs?

做以下修改删除的间距。

Making the following changes removed the spacings.

gridLayout = (GridLayout) findViewById(R.id.gridlayout_main);
gridLayout.setUseDefaultMargins(false);
gridLayout.setAlignmentMode(GridLayout.ALIGN_BOUNDS);
gridLayout.setRowOrderPreserved(false);
