在android中删除ListView顶部和底部的阴影？

Question

我创建了一个自定义listView,其行如下:

 <RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android"
  android:layout_width="fill_parent"  android:id="@+id/lay1" 
  android:layout_height="wrap_content" android:background="#ffffff">

  <TextView android:layout_width="fill_parent" android:textColor="#000000" android:id="@+id/text"
  android:layout_height="wrap_content" android:layout_toRightOf="@+id/check" 
  android:textSize="15dip" android:paddingBottom="5dip" android:paddingRight="10dip" android:paddingLeft="10dip"></TextView>

  <Button android:id="@+id/check"  android:layout_centerVertical="true"
          android:background="@drawable/uncheck" android:layout_width="wrap_content"
          android:layout_height="wrap_content" android:visibility="gone"></Button>

  <EditText android:layout_width="fill_parent" android:textColor="#000000" android:id="@+id/edit"
  android:layout_height="wrap_content"  android:background="@null" android:layout_below="@+id/text"
  android:textSize="15dip" android:paddingTop="5dip" android:paddingRight="10dip" android:paddingLeft="10dip"
  android:layout_toRightOf="@+id/check" android:paddingBottom="5dip" ></EditText>

</RelativeLayout>

我的主xml中使用的listview代码是:

<ListView android:layout_width="450dip" android:background="#FFFFFF" android:layout_height="340dip" 
  android:layout_marginLeft="9dip" android:layout_marginTop="10dip"  android:id="@+id/mainlist1" 
  android:divider="@drawable/grayline" 
    android:cacheColorHint="#00000000" ></ListView>

使用的适配器如下:

public class Adapter extends BaseAdapter {


        ArrayList<Row> row;
        private Context context;


        public Adapter(Context context, ArrayList<SongRow> songrow) {

            this.context = context;
            this.row = row;

        }

        public int getCount() {

            return row.size();
        }

        public Object getItem(int position) {
            return position;
        }

        public long getItemId(int position) {
            return position;
        }

        public View getView(int position, View convertView, ViewGroup parent) {

            long sub_id = row.get(position).getSub_id();
            String sub_title = row.get(position).getSub_title();
            String sub_text = row.get(position).getSub_text();

            if (convertView == null) {
                LayoutInflater inflat = (LayoutInflater)context.getSystemService(Context.LAYOUT_INFLATER_SERVICE);
                convertView = inflat.inflate(R.layout.mainrow, null);

            } else {
                LayoutInflater inflat1 = (LayoutInflater) context.getSystemService(Context.LAYOUT_INFLATER_SERVICE);
                convertView = inflat1.inflate(R.layout.mainrow, null);
                            }
            final TextView name = (TextView) convertView.findViewById(R.id.text);
            final EditText et = (EditText) convertView.findViewById(R.id.edit);
            name.setText(sub_title);
            et.setText(sub_text);
            et.setFilters(new InputFilter[] { new InputFilter() {
                public CharSequence filter(CharSequence src, int start,
                        int end, Spanned dst, int dstart, int dend) {
                       InputMethodManager mgr = (InputMethodManager) getSystemService(Context.INPUT_METHOD_SERVICE);
                       mgr.hideSoftInputFromWindow(et.getWindowToken(),0);
                       et.setCursorVisible(false);
                       return dst.subSequence(dstart, dend);    

                }
            } });
            et.setOnFocusChangeListener(new OnFocusChangeListener() {

                @Override
                public void onFocusChange(View v, boolean hasFocus) {
                    // TODO Auto-generated method stub
                    if (hasFocus) {
                         InputMethodManager mgr = (InputMethodManager) getSystemService(Context.INPUT_METHOD_SERVICE);
                         mgr.hideSoftInputFromWindow(et.getWindowToken(),0);
                         et.setCursorVisible(false);
                    }
                }

            });
            et.setOnClickListener(new OnClickListener() {
                @Override
                public void onClick(View v) {
                     InputMethodManager mgr = (InputMethodManager) getSystemService(Context.INPUT_METHOD_SERVICE);
                     mgr.hideSoftInputFromWindow(et.getWindowToken(),0);
                     et.setCursorVisible(false);

                }
            });
            return convertView;
        }
    }

并通过代码在主活动中调用适配器,如下所示:

Adapter s = new Adapter(MainActivity.this, row);
            mainlist.setAdapter(s);
            mainlist.setSelection(length-1);

我的编码工作正常.我的问题是,虽然显示可滚动的listview是在listview的顶部和底部投下阴影,但我不想显示它.我该如何移除阴影？

提前致谢

Answer 1

我假设你在谈论渐弱的边缘.要禁用它们:

android:fadingEdge="none"

要么

listView.setVerticalFadingEdgeEnabled(false);

UPDATE

正如Pim Reijersen在评论中指出的那样,android:fadingEdge已被弃用,从API级别14开始将被忽略.请使用:

android:fadingEdgeLength="0dp"

Answer 2

android:fadingEdgeLength 我没有为我工作,我使用和工作得很好 android:overScrollMode="never"

添加android:overScrollMode="never"到ScrollView

Answer 3

这对我有用

android:fadeScrollbars="false"
android:fadingEdge="none"
android:fadingEdgeLength="0dp"
android:cacheColorHint="#00000000"
android:overScrollMode="never"

Answer 4

在XML ScrollView中使用它:

android:overScrollMode="never"

您可以设置为"always","never"或"ifContentScrolls".
