在gridview的ImageView的高度

问题描述

我按照本指南使用网格视图中插入一个画廊图象：

I follow this guide to insert images in a gallery using grid view: http://developer.android.com/guide/topics/ui/layout/gridview.html

我编辑的imageadapter code如下：

I edited the imageadapter code as follow:

public class ImageAdapter extends BaseAdapter {
private Context mContext;

public ImageAdapter(Context c) {
    mContext = c;
}

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

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

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

@Override
public View getView(int position, View convertView, ViewGroup parent) {
    ImageView imageView;
    if (convertView == null) {  // if it's not recycled, initialize some attributes
        imageView = new ImageView(mContext);
        imageView.setId(R.id.img_gallery);

        imageView.setScaleType(ImageView.ScaleType.CENTER_CROP);
        imageView.setPadding(8, 8, 8, 8);
    } else {
        imageView = (ImageView) convertView;
    }

    imageView.setImageResource(mThumbIds[position]);
    return imageView;
}

// references to our images
private int[] mThumbIds = {R.drawable.itinerario1_1, R.drawable.itinerario1_1, R.drawable.itinerario1_1, R.drawable.itinerario1_1, R.drawable.itinerario1_1, R.drawable.itinerario1_1, R.drawable.itinerario1_1, R.drawable.itinerario1_1, R.drawable.itinerario1_1, R.drawable.itinerario1_1};

}

这是img_gallery XML

and this is img_gallery xml

<ImageView xmlns:android="http://schemas.android.com/apk/res/android" 
android:id="@+id/img_gallery"
android:layout_width="fill_parent"
android:layout_height="wrap_content"
android:background="#000000"
android:adjustViewBounds="true"/>

和这是主要的布局：

<LinearLayout  xmlns:android="http://schemas.android.com/apk/res/android" 
android:layout_width="fill_parent"
android:layout_height="fill_parent"
android:fillViewport="true" 
android:fadingEdge="none">
<GridView
    android:id="@+id/gridview"
    android:layout_width="fill_parent" 
    android:layout_height="fill_parent"
    android:verticalSpacing="0dp"
    android:horizontalSpacing="0dp"
    android:stretchMode="columnWidth"
    android:numColumns="2"
    android:gravity="center"
    android:padding="5dp"
/>

问题是，当我囤的应用程序，ImageView的有很多的顶部和底部填充的。我还试图将其设置为0在XML，但它不会改变。

the problem is that when i tun the app, imageview has a lot of top and bottom padding. I also tried to set it to 0 in the xml but it doesn't change.

推荐答案

您是在运行时设置填充 -

You are setting the padding on runtime-

删除此行 -

 imageView.setPadding(8, 8, 8, 8);
