卸下微胖在android的一个GridView [英] Removing the extra padding in a GridView in android

问题描述

我想删除出现在网格视图中的微胖。我有尺寸128×128，这将在网格被占用细胞的图像。但不知何故存在着被添加到网格的内容的额外的空间。

I want to remove the extra padding that appears in a grid view. I have images of the size 128*128 which will be occupying cells in the grid. But somehow there is an extra space that gets added to the contents of the grid.

经过一番研究，我能确定我有覆盖网格视图的listSelector财产。现在，这里是我的问题 - 我知道我必须在这里指定像一个XML绘制，但是以指定的？我试图用一个形状绘制与填充和中风设置为0dp无济于事。

After some research, I was able to determine that I have to override the listSelector property of the grid view. Now here's my question - I know I have to specify something like an xml drawable here, but what to specify in that?? I tried using a shape drawable with padding and stroke set to 0dp to no avail.

在此提出问题和回答<一href="http://stackoverflow.com/questions/5684543/how-to-avoid-space-between-imageview-and-gridview-in-linearlayout">here,但他们并没有给出什么可绘制必须包含。

The question is asked and answered here, but they haven't given what the drawable must contain.

可以有一个人帮助我。谢谢！

Can some one help me with this. Thanks!

编辑：好的 - 我有UI的这里 山副本。而对于同样的XML布局如下：

Ok - here's a copy of the UI that I have. And the XML layout for the same is as follows:

<GridView android:id="@+id/GV_A2ZMenu" android:layout_width="fill_parent"
    android:layout_height="wrap_content" android:numColumns="4"
            android:layout_gravity="top" android:stretchMode="columnWidth"
    android:gravity="center" android:listSelector="@null" />

和我使用的是BaseAdapter类来填充GridView控件。下面是它的code：

And I am using a BaseAdapter class to populate the gridView. Here's its code:

public class AtoZMenu extends BaseAdapter {

private static Context AppC;

private Integer[] MenuImg = { R.drawable.alphabet_a, R.drawable.alphabet_b,
        R.drawable.alphabet_c, R.drawable.alphabet_d,
        R.drawable.alphabet_e, R.drawable.alphabet_f,
        R.drawable.alphabet_g, R.drawable.alphabet_h,
        R.drawable.alphabet_i, R.drawable.alphabet_j,
        R.drawable.alphabet_k, R.drawable.alphabet_l,
        R.drawable.alphabet_m, R.drawable.alphabet_n,
        R.drawable.alphabet_o, R.drawable.alphabet_p,
        R.drawable.alphabet_q, R.drawable.alphabet_r,
        R.drawable.alphabet_s, R.drawable.alphabet_t,
        R.drawable.alphabet_u, R.drawable.alphabet_v,
        R.drawable.alphabet_w, R.drawable.alphabet_x,
        R.drawable.alphabet_y, R.drawable.alphabet_z };

public AtoZMenu(Context C) {
    AppC = C;
}

public int getCount() {
    return MenuImg.length;
}

public Object getItem(int position) {
    return null;
}

public long getItemId(int position) {
    return 0;
}

public View getView(int position, View convertView, ViewGroup parent) {
    ImageView IV;
    float density = AppC.getResources().getDisplayMetrics().density;

    if (convertView == null) {
        IV = new ImageView(AppC);
        IV.setMaxHeight((int) (1));
    } else {
        IV = (ImageView) convertView;
    }
    IV.setImageResource(MenuImg[position]);
    return IV;
}
 }

可以看出错误了？

注意：最后，我结束了在这使得更好的网格表布局实现类似的屏幕

Note: In the end I ended up implementing a similar screen in a table layout which renders much better grids.

推荐答案

是的，我有同样的问题。你想设置listSelector为@null：

Yep, I've had the same problem. You want to set the listSelector to @null:

<!-- Setting the listSelector to null removes the 5px border -->
<GridView
    android:id="@+id/view"
    android:layout_width="fill_parent"
    android:layout_height="wrap_content"
    android:listSelector="@null" />

另外，请尝试以下操作：

Also, try the following:

myGridView.setStretchMode(GridView.STRETCH_COLUMN_WIDTH);

我看你可以在XML做到这一点，但我没有，当我有这个同样的问题;不知道为什么。

I see you can do this in the XML, but I didn't when I had this same problem; not sure why.

我也硬codeD按键高度：

I also hard-coded the key height:

float density = getContext().getResources().getDisplayMetrics().density;
mKeyHeight = (int) (56 * density);
....
@Override
public View getView(int position, View convertView, ViewGroup parent) {
    ImageButton b = (ImageButton) convertView;
    if (b == null) {
        b = new ImageButton(getContext());
        b.setMinimumHeight(mKeyHeight);
        b.setBackgroundResource(R.drawable.btn_keyboard_key);
        b.setOnClickListener(this);
    }
}

抱歉没有给一个precise答案，所以让我知道，如果你之后还需要帮助。

Sorry about not giving a precise answer, so let me know if you still need help after that.
