我有一個GridView，以顯示與按鈕圖像，但我有一個問題，它只能顯示第一行，我把它的數據3行..GridView中只顯示第一行
這是我的佈局代碼：

在適配器我沒有任何掐死，但如果你需要我把它複製here..I與FILL_PARENT WRAP_CONTENT等，但沒有任何作品嚐試..
編輯：適配器代碼：
public class GridAdapter extends BaseAdapter {
private LayoutInflater inflater;
private Activity activity;
private List<String> images = new ArrayList<String>();
private OnDeleteItem mListener;
public interface OnDeleteItem {
public void onDeleteItemClick(String path);
}
public GridAdapter(Activity inyectActivity, List<String> listImages) {
activity = inyectActivity;
images = listImages;
inflater = LayoutInflater.from(activity);
mListener = (ReviewFilesActivity) activity;
}
public void notifyDataSetChanged(List<String> dataImages) {
images = dataImages;
super.notifyDataSetChanged();
}
public View getView(final int position, View convertView, ViewGroup parent) {
GridViewHolder vHolder;
if (convertView == null) {
convertView = inflater.inflate(R.layout.grid_view, null);
vHolder = new GridViewHolder(convertView, mListener);
vHolder.image.setImageBitmap(ImagesUtilities.decodeSampledBitmapFromResource(images.get(position), 400, 400));
vHolder.path = images.get(position);
vHolder.delete.setOnClickListener(new View.OnClickListener() {
@Override
public void onClick(View v) {
mListener.onDeleteItemClick(images.get(position));
}
});
} else {
vHolder = (GridViewHolder) convertView.getTag();
}
return convertView;
}
@Override
public int getCount() {
return images.size();
}
@Override
public Object getItem(int position) {
return null;
}
@Override
public long getItemId(int position) {
return 0;
}
static class GridViewHolder {
public GridViewHolder(View view, OnDeleteItem listener) {
ButterKnife.inject(this, view);
}
@InjectView(R.id.grid_item_image)
ImageView image;
@InjectView(R.id.deleteButton)
Button delete;
String path;
public String getPath() {
return path;
}
}
}
編輯2：
我做了更簡單的XML，但行不顯示。

適配器代碼將是有益的 – danijoo
好的我將它複製 – colymore
您的佈局是過於複雜，我懷疑你真的需要這麼多的嵌套的線性佈局和相對佈局。我的第一個暗示是你的gridview的高度與父對象相匹配，但沒有足夠的空間來顯示它，並且（遠）外部scollview的子對象也有匹配父對象的高度，所以滾動不起作用。 – rekaszeru
