Question

我有一个基于 GridView 的日历。我有以下的 XML 版式, 由选择器设置为空, 因此 < code> 和 mid: listSelector="@null" 。根据我从这个网站得到的建议。现在我要从 GridView 右侧获得一些宽的像素条。为什么? 我已尝试了所有可以使用的方法。以下是我的 XML 版式 :

        <LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
            android:layout_width="fill_parent"
            android:layout_height="match_parent"
            android:orientation="vertical" >

            <GridView
                android:id="@+id/calendar"
                android:layout_width="fill_parent"
                android:layout_height="match_parent"
                android:horizontalSpacing="-1px"
                android:numColumns="7"
                android:stretchMode="columnWidth" 
                android:gravity="center"
                android:verticalSpacing="-1px"
                android:listSelector="@null" >

            </GridView>

        </LinearLayout>

我得到的是这张照片:

Answer 1

This space is due to imperfect calculation for each row of your grid. For example your device width is 320 px and you have 7 rows, try any calculation that meets 320 px. If the width of each cell is 45.71428571428571 px, only then it can be reduced.

其他选项

apply android:gravity="center" property in you grid so that spaces will equally divided from left to right

Answer 2

以我的情况来看,我有一个水平间距 1DP

android:horizontalSpacing="1dp"

为了解决这个问题,我把正确的垫子放成 -1dp

android:paddingRight="-1dp"

虽然我原本希望左侧有位子,

Answer 3

尝试使用

android:layout_margin="0dp"
android:padding="0dp"

Also you might have that space allocated for the scroll bar.
And why do you have your vertical and horizontal spacing with negative values?

Answer 4

I had the same problem though in my case I didn t have control over the GridView instance so I couldn t read the column width. Nevertheless I could subclass its container.
This isn t very orthodox but you can override the onMeasure method and add a few pixels.
Something like this:

@Override
protected void onMeasure(int widthMeasureSpec, int heightMeasureSpec) {
    final int RIGHT_MARGIN_OVERSIZE_DIP = 6;
    super.onMeasure(widthMeasureSpec, heightMeasureSpec);
    int width = this.getMeasuredWidth()
    int overSize = (int)((getResources().getDisplayMetrics().density*RIGHT_MARGIN_OVERSIZE_DIP) + 0.5f);
    widthMeasureSpec = MeasureSpec.makeMeasureSpec(width + overSize, MeasureSpec.getMode(widthMeasureSpec));        
    super.onMeasure(widthMeasureSpec, heightMeasureSpec);
}

Answer 5

grid.setColumnWidth(grid.getColumnWidth()+1);

This will get the current ColumnWidth and add 1 pixel to it. Remember to use this after onCreateView,since the grid needs to be initialized before that.

另外,您的网格视图应该使用相匹配的( 高度和宽度) 。列中的图像/ 布置也应该与相匹配的相匹配。
