我的Android应用程序中有一个GridView。当我点击BACK按钮时,我想重新录制所有图像。我不知道怎么弄这个?
gridview.setAdapter(adapter);
这是我在适配器中的getView():
public View getView(int position, View convertView, ViewGroup parent) {
ViewHolder holder = null;
if (convertView == null) {
convertView = inflater.inflate(R.layout.item_addimage_grid,
parent, false);
holder = new ViewHolder();
holder.image = (ImageView) convertView
.findViewById(R.id.item_grida_image);
convertView.setTag(holder);
} else {
holder = (ViewHolder) convertView.getTag();
}
if (position == Bimp.SelectBitmap.size()) {
holder.image.setImageBitmap(BitmapFactory.decodeResource(
getResources(), R.drawable.pic_add));
if (position == 3) {
holder.image.setVisibility(View.GONE);
}
} else {
holder.image.setImageBitmap(Bimp.SelectBitmap.get(position)
.getBitmap());
}
return convertView;
}
public class ViewHolder {
public ImageView image;
}
当我点击此按钮时,我会转到另一个片段:
case R.id.title_btn_left:
Bimp.SelectBitmap.clear();
FragmentTransaction ft = getFragmentManager().beginTransaction();
SearchFragment searchFragment = new SearchFragment();
ft.replace(R.id.fl_content, searchFragment);
ft.commit();
break;
现在,当我点击后退按钮时,我设置了 Bimp.SelectBitmap.clear();
。但是,当我进入选择图像的片段时,它太慢并且无法响应 gridview.setOnItemClickListener()。我认为,因为当我去另一个片段时图像不是回忆。
答案 0 :(得分:1)
将setRecyclerListener(...)
设置为GridView
:
gridview.setRecyclerListener(new RecyclerListener() {
@Override
public void onMovedToScrapHeap(View view) {
//get Bitmap by 'view' and release it here
}
});
希望这有帮助!
