在我的活動中,我必須展示一些圖片。我在我的活動中使用了gridview,每行應該顯示4個圖像(每個圖像的寬度是屏幕的25%)。我需要減小寬度相同的圖像的高度。Android,如何降低圖像適配器中圖像的高度?
所以,在我的UI中我有一個gridview和我的imageAdapter將圖片排列到屏幕上。這是適配器的代碼:
public class ContestantsPhotoAdapter extends BaseAdapter {
private LayoutInflater myInflater;
private Bitmap[] bitmapList;
public ContestantsPhotoAdapter(Context c) {
myInflater = LayoutInflater.from(c);
}
public void setData(Bitmap[] bmImages){
bitmapList = bmImages;
Log.i("ContestantsPhotoAdapter", "Images passed to the adapter.");
}
@Override
public int getCount() {
return bitmapList.length;
}
@Override
public Object getItem(int position) {
return position;
}
@Override
public long getItemId(int position) {
return position;
}
public View getView(int position, View convertView, ViewGroup parent){
ViewHolder holder;
if (convertView == null) {
convertView = myInflater.inflate(R.layout.grid_contestantsphoto, null);
holder = new ViewHolder();
holder.ivIcon = (ImageView) convertView.findViewById(R.id.imvContestantsPhoto_icon);
convertView.setTag(holder);
} else {
holder = (ViewHolder) convertView.getTag();
}
holder.ivIcon.setImageBitmap(bitmapList[position]);
return convertView;
}
static class ViewHolder {
ImageView ivIcon;
}
}
grid_contestantsphoto.xml是:
<?xml version="1.0" encoding="utf-8"?>
<ImageView
xmlns:android = "http://schemas.android.com/apk/res/android"
android:id = "@+id/imvContestantsPhoto_icon"
android:layout_width = "wrap_content"
android:layout_height = "100dip"
android:contentDescription = "@string/menu_contentdescription" />
我的問題是,當我改變android:layout_height = "100dip"
它不生效,始終高度和以前一樣。
請告訴我如何縮小尺寸。謝謝。
謝謝,但不幸沒有奏效。仍然高度與原來一樣。 – Hesam 2012-04-07 18:35:10
再次感謝,但我認爲這不是正確的方法,因爲沒有任何影響。 – Hesam 2012-04-07 18:53:27
