Question

我试图通过gridView进行过滤部分。在宽屏幕上它很好。但是当它的小屏幕无法正常工作时。（一个视图是两次或三次，一些是消失的）这是因为gridView项目的缩小和滚动正在出现。所以我试图删除gridView滚动。

我的活动是。

我以编程方式添加gridView项目：

                }
            }
        });

和过滤器按钮适配器

public class FilterButtonAdapter extends BaseAdapter {

    private Context context;
    private final String[] filterValues;
    private List<String> checkedFilterValues = new ArrayList<String>();


    public FilterButtonAdapter(Context context, String[] filterValues, List<String> checkedFilterValues){
        this.context = context;
        this.filterValues = filterValues;
        this.checkedFilterValues = checkedFilterValues;
    }
    @Override
    public int getCount() {
        return filterValues.length;
    }

    @Override
    public Object getItem(int i) {
        return null;
    }

    @Override
    public long getItemId(int i) {
        return 0;
    }

    @Override
    public View getView(int position, View convertView, ViewGroup viewGroup) {
        LayoutInflater inflater = (LayoutInflater)context.getSystemService(Context.LAYOUT_INFLATER_SERVICE);

        View gridView;
        if(convertView == null){

            gridView = new View(context);
            gridView = inflater.inflate(R.layout.layout_button, null);

            final TextView textView = (TextView)gridView.findViewById(R.id.filter_button);
            textView.setText(filterValues[position]);

            boolean contain = false;
            for(int i = 0; i < Filter.blocks_selected.size(); i++){
                if(filterValues[position].equals(checkedFilterValues.get(i)))
                {
                    gridView.setBackgroundResource(R.drawable.button_enabled);
                    contain = true;
                    break;
                }
            }
            if(!contain){
                gridView.setBackgroundResource(R.drawable.button_disabled);
            }
        } else gridView = (View)convertView;
        return gridView;
    }
}

过滤类：

public class Filter {

    public static String price = "any";
    public static long priceMax = 0;
    public static long priceMin = 0;
    public static final String[] filter_blocks = new String[]{
            "any", "A", "B", "C"
    };
    public static final String[] filter_floors = new String[]{
            "any", "1", "2", "3", "4", "5", "6",
            "7", "8", "9", "10", "11", "12+"
    };

    public static List<String> blocks_selected = new ArrayList<String>(){{
        add("any");
    }
    };

    public static List<String> floor_selected = new ArrayList<String>(){{
        add("any");
    }
    };

    public static int floor = 10;

}

Answer 1

试试这个

ViewCompat.setNestedScrollingEnabled(gridView, true);

Answer 2

请勿在{{1}}内使用GridView，因为两者都具有滚动功能，因此无法正常使用。

使用ScrollView代替NestedScrollView。

ScrollView就像NestedScrollView一样，但它支持表演作为ScrollView滚动nested和parent同时适用于新旧版本 Android版本。默认情况下启用嵌套滚动。

请参阅documentation。

更新您的布局结构，如下所示：

child

Android：gridView设置不可滚动？
