我正在使用GridLayout(支持)ImageView在我的应用程序中显示s.有3列5行.问题是细胞在GridLayout它们之间自动获得一些空间.我没有为细胞设置任何填充或边距.请参考下图.动态添加所有单元格,以下是添加这些单元格的方法.

获得屏幕宽度和高度:

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

将视图添加到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:

<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" …

这个GridLayout在我的应用程序中有很多级别.每个级别都有不同的行数和列数.我认为这个GridLayout是我用来满足我需求的最佳选择.此外,所有这些都需要在运行时以编程方式完成.

我无法理解如何使用GridLayout.spec().我试图遵循这个优秀的例子,但却无法完全掌握它.比方说,我想要一个包含3列和4行的GridLayout.

GridLayout.LayoutParms params1 = new GridLayout.Layout(rowSpec, columnSpec);  //what's parameters?

gameplayGridLayout.setColumnCount(3);
gameplayGridLayout.setRowCount(4);

puzzle.addView(gameplayGridLayout, params1);

在我上面的链接示例中,他使用下面的代码来设置"specs".

Spec row1 = GridLayout.spec(0, 2);
Spec row2 = GridLayout.spec(2);
Spec row3 = GridLayout.spec(3);
Spec row4 = GridLayout.spec(4, 2);

Spec col0 = GridLayout.spec(0);
Spec col1 = GridLayout.spec(1); 
Spec colspan2 = GridLayout.spec(0, 2);

我也不了解这些变量的参数.我试过阅读文档,但它没有给我任何清晰度.有人可以帮助我使用3x4 GridLayout的示例代码,这也有助于解释Specs是什么？

我使用 GridLayout。一切正常。但我需要在列之间和行之间设置空间（例如 10dp）。我怎么能做到这一点？

主文件：

            <GridLayout
                android:id="@+id/categoriesContainer"
                android:layout_width="0dp"
                android:layout_height="wrap_content"
                android:verticalSpacing="10dp"
                app:layout_constraintEnd_toEndOf="@+id/birthDateContainer"
                app:layout_constraintStart_toStartOf="@+id/birthDateContainer"
                app:layout_constraintTop_toBottomOf="@+id/birthDateContainer">


            </GridLayout>

profile_category_active.xml

<?xml version="1.0" encoding="utf-8"?>
<layout 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.support.constraint.ConstraintLayout
        android:id="@+id/profileCategoryContainer"
        android:layout_width="wrap_content"
        android:layout_height="wrap_content">       


        <TextView
            android:id="@+id/categoryNameTextView"
            android:layout_width="wrap_content"
            android:layout_height="wrap_content"
            android:layout_marginBottom="5dp"
            android:layout_marginEnd="30dp"
            android:layout_marginLeft="5dp"
            android:layout_marginRight="30dp"
            android:layout_marginStart="5dp"
            android:layout_marginTop="5dp"
            android:ellipsize="end"
            android:maxLines="1"
            android:text="TextView"                />
    </android.support.constraint.ConstraintLayout>
</layout>

活动：我以编程方式添加行：

 GridLayout gridLayout = findViewById(R.id.categoriesContainer);
    gridLayout.setColumnCount(columnCount);
    LayoutInflater inflater = (LayoutInflater) getSystemService(Context.LAYOUT_INFLATER_SERVICE);
    for (int index = 0; index < 10; index++) {
     View profileCategoryActive = inflater.inflate(R.layout.profile_category_active, null, false);
            categoriesGridContainer.addView(profileCategoryActive);
            ConstraintLayout profileCategoryContainer = profileCategoryActive.findViewById(R.id.profileCategoryContainer); …
