Android的GridView控件调节屏幕尺寸 [英] Android gridview adjusting to screen size

问题描述

我的应用程序的网格视图中有3行3列。我想这填满屏幕，而不管设备的屏幕大小。

The grid view of my application has 3 rows and 3 columns. I want this to fill the screen ,irrespective of the screen size of the device.

我试图让窗口的大小，并相应设置的LayoutParams。但是，这是不是给一个精确对准，因为它的工作原理与weightsum在LinearLayout中。

I tried getting window size and setting the layoutparams accordingly. But this is not giving a perfect alignment as it works with weightsum in linearlayout.

所以，我们可以使用weightsum的GridView的或有可用于任何其他Android财产。 非常感谢您的时间和响应。

So can we use weightsum for gridview or is there any other android property that can be used. Thanks a lot for time and response.

<GridView
                xmlns:android="http://schemas.android.com/apk/res/android"
                android:id="@+id/gridview"
                android:layout_width="fill_parent"
                android:layout_height="fill_parent"
                android:layout_below="@+id/text1view"
                android:background="@drawable/home_bg"
                android:gravity="center"
                android:horizontalSpacing="10dip"
                android:numColumns="3"
                android:stretchMode="columnWidth" />

每个网格产品

each grid item is

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

<ImageView
    android:id="@+id/grid_item_image"
    android:layout_width="wrap_content"
    android:layout_height="75dip"
    android:layout_margin="0dip"
    android:padding="0dip" >
</ImageView>

<TextView
    android:id="@+id/grid_item_text"
    android:layout_width="wrap_content"
    android:layout_height="wrap_content"
    android:layout_alignParentBottom="true"
    android:layout_below="@+id/grid_item_image"
    android:gravity="center_horizontal"
    android:padding="0dip"
    android:textColor="#000000"
    android:textSize="10sp" >
</TextView>

$ C $适配器C：

code of the adapter :

    @Override
public View getView(final int position, View convertView, ViewGroup parent) {
    ViewHolder holder;

    if (convertView == null) {
        LayoutInflater mInflater = (LayoutInflater) mContext
                .getSystemService(Context.LAYOUT_INFLATER_SERVICE);
        convertView = mInflater.inflate(R.layout.griditems, null);
        holder = new ViewHolder();
        holder.text1 = (TextView) convertView
                .findViewById(R.id.grid_item_text);

        holder.image = (ImageView) convertView
                .findViewById(R.id.grid_item_image);

        // if it's not recycled, initialize some attributes
        holder.image.setImageResource(gridItemIds[position]);
        holder.text1.setText(gridTitles[position]);
        int h = mContext.getResources().getDisplayMetrics().densityDpi;

        // holder.image.setLayoutParams(new LayoutParams(h-50,h-50));
        convertView.setLayoutParams(new GridView.LayoutParams(h - 45,
                h - 39));
        // holder.image.setScaleType(ImageView.ScaleType.CENTER_CROP);
        // holder.image.setScaleType(ImageView.ScaleType.FIT_XY);
        // holder.image.setPadding(20, 20, 20, 20);

        // convertView.setLayoutParams(new GridView.LayoutParams(Utils
        // .getLayoutParameter(), Utils.getLayoutParameter()+50));

        holder.image.setOnClickListener(new View.OnClickListener() {

            @Override
            public void onClick(View view) {
                new ModuleManager().startModuleACtivity(position, mContext);
            }
        });
        convertView.setTag(holder);
    } else {

        holder = (ViewHolder) convertView.getTag();

    }

    return convertView;
}

static class ViewHolder {
    TextView text1;
    ImageView image;

}

请参见行

convertView.setLayoutParams(new GridView.LayoutParams(h-45, h-39));

我来到这个值对不同大小的仿真器的一些试验。 但我不认为它是一种正确的方式来定义的高度和宽度。

i arrived at this value with some trials on different size emulator. But i dont think its a right way to define height and width.

推荐答案

据我理解你的问题，因为你还没有发布任何code，你正在尝试做的是，你要GridView控件出现在全屏。

As far as i understood your question, as you have not posted any code, what you are trying to do is, you want gridview to appear on full screen.

首先，你必须使用一些布局，把你的GridView中执行以下操作：

Firstly you must be using some layout to put your gridview in. Do the following:

请高度和宽度的布局，以填补父：

Make height and width of the layout to fill parent:

android:layout_width="fill_parent"
android:layout_height="fill_parent"

然后，设置高度和宽度你的GridView来FILL_PARENT为好。

then, set height and width of your gridview to fill_parent as well.

好了，这是你可能会一直这样只是一个假设的解决方案。把一些code就会好很多。希望这对你的作品。

Well, this is just a supposed solution that you might have been working this way. putting some code would be much better. Hope this works for you.

更新：  那么问题可能在于这里：

Update: Well the problem may lie here:

 convertView.setLayoutParams(new GridView.LayoutParams(h-45, h-39));

更改为：

 LinearLayout.LayoutParams params = new LinearLayout.LayoutParams(LinearLayout.LayoutParams.FILL_PARENT, LinearLayout.LayoutParams.FILL_PARENT);
 convertView.setLayoutParams(new GridView.LayoutParams(params));

希望这对你的作品。

Hope this works for you.
