我不明白为什么无论我做什么,我的网格视图中都只有一列......令人沮丧。
活动的xml
<?xml version="1.0" encoding="utf-8"?>
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:layout_width="match_parent"
android:layout_height="match_parent"
android:orientation="vertical">
<GridView
android:id="@+id/gridView_album"
android:layout_width="match_parent"
android:layout_height="match_parent"
android:numColumns="2"
android:verticalSpacing="10dp"
android:horizontalSpacing="10dp"
android:stretchMode="columnWidth"
android:gravity="center" />
</LinearLayout>
对于网格视图中的每个项目(这在我的适配器中被夸大了)
<?xml version="1.0" encoding="utf-8"?>
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:orientation="vertical" >
<LinearLayout
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:layout_marginLeft="5dp"
android:layout_marginRight="5dp"
android:orientation="vertical" >
<TextView
android:id="@+id/textView_albumTitle"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:text="album title" />
</LinearLayout>
<ImageView
android:id="@+id/imageView1"
android:layout_width="105dp"
android:layout_height="100dp"
android:src="@drawable/abs__ab_share_pack_holo_light" />
<LinearLayout
android:layout_width="wrap_content"
android:layout_height="wrap_content" >
<ImageView
android:id="@+id/imageView2"
android:layout_width="20dp"
android:layout_height="20dp"
android:layout_marginLeft="5dp"
android:layout_marginTop="5dp"
android:src="@drawable/abs__ab_solid_light_holo" />
<ImageView
android:id="@+id/imageView3"
android:layout_width="20dp"
android:layout_height="20dp"
android:layout_marginLeft="5dp"
android:layout_marginTop="5dp"
android:src="@drawable/abs__ab_solid_light_holo" />
<ImageView
android:id="@+id/imageView4"
android:layout_width="20dp"
android:layout_height="20dp"
android:layout_marginLeft="5dp"
android:layout_marginTop="5dp"
android:src="@drawable/abs__ab_solid_light_holo" />
<ImageView
android:id="@+id/imageView5"
android:layout_width="20dp"
android:layout_height="20dp"
android:layout_marginLeft="5dp"
android:layout_marginTop="5dp"
android:src="@drawable/abs__ab_solid_light_holo" />
</LinearLayout>
</LinearLayout>
和我的适配器的 getView
@Override
public View getView(int position, View convertView, ViewGroup parent) {
View v = convertView;
JsonAlbum jsonAlbum = (JsonAlbum) getItem(position);
ArrayList<JsonAlbumImage> jsonAlbumImageArray = jsonAlbum.album_image_list;
if (v == null) {
LayoutInflater vi = (LayoutInflater) getContext().getSystemService(
Context.LAYOUT_INFLATER_SERVICE);
v = vi.inflate(R.layout.album_list_row, null);
}
TextView textView_albumTitle = (TextView) v.findViewById(R.id.textView_albumTitle);
textView_albumTitle.setText(jsonAlbum.title);
ImageView imageView1 = (ImageView)v.findViewById(R.id.imageView1);
ImageView imageView2 = (ImageView)v.findViewById(R.id.imageView2);
ImageView imageView3 = (ImageView)v.findViewById(R.id.imageView3);
ImageView imageView4 = (ImageView)v.findViewById(R.id.imageView4);
ImageView imageView5 = (ImageView)v.findViewById(R.id.imageView5);
ArrayList<ImageView> imageViewList = new ArrayList<ImageView>();
imageViewList.add(imageView1);
imageViewList.add(imageView2);
imageViewList.add(imageView3);
imageViewList.add(imageView4);
imageViewList.add(imageView5);
int imageCount = Math.min( imageViewList.size(), jsonAlbumImageArray.size());
for(int i=0; i < imageCount; ++i)
{
ImageView imageView = imageViewList.get(i);
imageView.setScaleType(ImageView.ScaleType.CENTER_CROP);
JsonAlbumImage jsonAlbumImage = jsonAlbumImageArray.get(i);
imageLoader.displayImage(jsonAlbumImage.url_image, imageView, options);
}
Log.i("debug", "width: "+ Integer.toString(v.getWidth()));
return v;
}
