删除空间或更改android中视图之间的颜色
如下图所示，按钮和文本视图之间存在间隙。我需要删除此空间或我需要将其颜色更改为原色。这是我的代码和快照

由于使用了public class ProductAdapter extends ArrayAdapter<Product> {
ArrayList<Boolean> positionArray;
public ProductAdapter(Context context, ArrayList<Product> products){
super(context,0,products);
positionArray = new ArrayList<Boolean>(products.size());
for(int i =0;i<products.size();i++){
positionArray.add(false);
}
}
public static class ViewHolder{
TextView tv_price,tv_prodName, tv_details, tv_location, quantity;
ImageView imgView_productImage;
CheckBox checkBox;
Button bntUp,btnDown;
}
//When a listview recycles views , it recycles its present state as well as listeners attached to it.if the checkbox was checked and has a
// onCheckedChangeListener set, both will remain a part of recycled view based on position.
// So it is our responsibility to reset all states and remove previous listeners.
@NonNull
@Override
public View getView(final int position, View convertView, ViewGroup parent) {
final ViewHolder viewHolder;
Product product = getItem(position);
if(convertView==null){
convertView = LayoutInflater.from(getContext()).inflate(R.layout.list_product_item,parent, false);
viewHolder = new ViewHolder();
viewHolder.imgView_productImage = (ImageView)convertView.findViewById(R.id.list_item_imgView_productImage);
viewHolder.tv_price = (TextView)convertView.findViewById(R.id.listItem_tv_price);
viewHolder.tv_prodName = (TextView)convertView.findViewById(R.id.listItem_tv_productName);
viewHolder.tv_location = (TextView)convertView.findViewById(R.id.listItem_tv_location);
viewHolder.tv_details = (TextView)convertView.findViewById(R.id.listItem_tv_productDetail);
viewHolder.checkBox = (CheckBox)convertView.findViewById(R.id.listProd_checkbox);
viewHolder.bntUp = (Button)convertView.findViewById(R.id.listProd_up);
viewHolder.btnDown = (Button)convertView.findViewById(R.id.listProd_down);
viewHolder.quantity = (TextView)convertView.findViewById(R.id.listItem_quantity);
convertView.setTag(viewHolder);
}else{
viewHolder = (ViewHolder)convertView.getTag();
viewHolder.checkBox.setOnCheckedChangeListener(null); //
}
viewHolder.tv_price.setText("$" + String.valueOf(product.getPrice()));
viewHolder.tv_prodName.setText(product.getProductName());
viewHolder.tv_location.setText(product.getLocation());
viewHolder.tv_details.setText(product.getProductDetail());
viewHolder.imgView_productImage.setImageBitmap(MifareUtilities.getDecodeImage(product.getProductImage()));
viewHolder.checkBox.setChecked(positionArray.get(position));
int visible = positionArray.get(position) == true ? View.VISIBLE : View.GONE;
viewHolder.checkBox.setVisibility(visible);
viewHolder.bntUp.setVisibility(visible);
viewHolder.btnDown.setVisibility(visible);
viewHolder.quantity.setVisibility(visible);
viewHolder.quantity.setText(String.valueOf(product.getQuantity()));
viewHolder.checkBox.setOnCheckedChangeListener(new CompoundButton.OnCheckedChangeListener() {
@Override
public void onCheckedChanged(CompoundButton buttonView, boolean isChecked) {
if(isChecked){
positionArray.set(position,true);
//show buttons
changeVisibility(viewHolder,View.VISIBLE);
}else {
positionArray.set(position,false);
changeVisibility(viewHolder,View.GONE);
}
}
});
return convertView;
}
public void changeVisibility(ViewHolder viewHolder, int visibility){
viewHolder.bntUp.setVisibility(visibility);
viewHolder.btnDown.setVisibility(visibility);
viewHolder.quantity.setVisibility(visibility);
viewHolder.checkBox.setVisibility(visibility);
}
}
，这种情况正在发生。使用Button代替TextView。
＃。我修改了您的XML并删除了一些冗余属性，并使用正确的Button和ImageView更新了TextView和weight。
＃。我已将属性height添加到android:background="?attr/selectableItemBackground"，以便在点击时显示LinearLayout效果。
