图像

Question

我有一个包含所有文字和图片的布局文件。我想留下一些文本和图像的空白，但也删除它从布局文件中占用的空间。所以我使用setVisibility并使用TextUtils.isEmpty删除文本，如果它的空白（＆＃34;＆＃34;）

我不确定如何删除图像空间。每次我不想要图片时都可以使用ic_launcher，只要它匹配ic_launcher setVisibility（GONE）

public class BasicAdapter extends RecyclerView.Adapter<BasicAdapter.ViewHolder> {

List<AdapterData> mItems;

public BasicAdapter() {
    super();
    mItems = new ArrayList<>();
    AdapterData data = new AdapterData();
    data.setText("dummy text");
    data.setImage(R.drawable.image_one);
    mItems.add(data);

    data = new AdapterData();
    data.setText("");
    data.setImage(R.drawable.ic_launcher);
    mItems.add(data);

    data = new AdapterData();
    data.setText("");
    data.setImage(R.drawable.image_two);
    mItems.add(data);

    data = new AdapterData();
    data.setText("dummy text");
    data.setImage(R.drawable.ic_launcher);
    mItems.add(data);

    data = new AdapterData();
    data.setText("dummy text");
    data.setImage(R.drawable.image_three);
    mItems.add(data);




}

@Override
public ViewHolder onCreateViewHolder(ViewGroup viewGroup, int i) {
    View v = LayoutInflater.from(viewGroup.getContext())
            .inflate(R.layout.test2, viewGroup, false);
    return new ViewHolder(v);
}

@Override
public void onBindViewHolder(ViewHolder viewHolder, int i) {
    AdapterData data = mItems.get(i);
    viewHolder.text.setText(data.getText());
    viewHolder.image.setImageResource(data.getImage());




    if(TextUtils.isEmpty(data.getText())){
        viewHolder.text.setVisibility(View.GONE);
    }else{
        viewHolder.text.setVisibility(View.VISIBLE);
    }





}


@Override
public int getItemCount() {

    return mItems.size();
}

class ViewHolder extends RecyclerView.ViewHolder{


    public TextView text;
    public ImageView image;




    public ViewHolder(View itemView) {
        super(itemView);
        text = (TextView)itemView.findViewById(R.id.textView1);
        image = (ImageView)itemView.findViewById(R.id.imageView1);


    }
}
}
