我要实现这种界面效果

可以左右滑动
我的方法是HorizontalScrollView包裹GridView左右滑动前面添加一个imageview来实现

<HorizontalScrollView

                android:id="@+id/hl_user_photo"

                android:layout_width="match_parent"

                android:layout_height="@dimen/height_348"

                android:layout_marginLeft="@dimen/margin_36"

                android:paddingBottom="@dimen/margin_32"

                android:scrollbars="none">



                <LinearLayout

                    android:layout_width="match_parent"

                    android:layout_height="match_parent"

                    android:orientation="horizontal"

                    >



                    <ImageView

                        android:id="@+id/first_image"

                        android:layout_width="167dp"

                        android:layout_height="match_parent"

                        android:layout_alignParentTop="true"

                        android:scaleType="centerCrop"

                        android:src="@drawable/picture_moren" />



                    <LinearLayout

                        android:id="@+id/id_gallery"

                        android:layout_marginLeft="7dp"

                        android:layout_width="match_parent"

                        android:layout_height="match_parent"

                        android:orientation="horizontal">



                        <GridView

                            android:id="@+id/gridview"

                            android:layout_width="fill_parent"

                            android:layout_height="wrap_content"

                            android:layout_gravity="center"

                            android:columnWidth="81dp"

                            android:horizontalSpacing="5dp"

                            android:verticalSpacing="5dp"></GridView>

                    </LinearLayout>

                </LinearLayout>

            </HorizontalScrollView>

可以实现滑动,但是效果不对....
实际效果是前面的 imageview 不会显示,必须向右拖动才能显示, 我想要的效果是刚出来就显示那个imageview的,但是实际上不会那样显示我的主要代码为:

mHlUserPhoto = (HorizontalScrollView) findViewById(R.id.hl_user_photo);

        gridView = (GridView) findViewById(R.id.gridview);

        mGallery = (LinearLayout) findViewById(R.id.id_gallery);

        mInflater = LayoutInflater.from(this);

adapter = new GridViewAdapter(mImgIds, mGallery, mInflater);

        gridView.setAdapter(adapter);



        int size = mImgIds.length;

        DisplayMetrics dm = new DisplayMetrics();

        getWindowManager().getDefaultDisplay().getMetrics(dm);

        float density = dm.density;



        int columnsNum = size % 2 == 0 ? size / 2 : size / 2 + 1;

        int allWidth = (int) (86 * columnsNum * density);

        //int itemWidth = (int) (85 * density);

        LinearLayout.LayoutParams params = new LinearLayout.LayoutParams(

                allWidth, LinearLayout.LayoutParams.MATCH_PARENT);





        gridView.setLayoutParams(params);

        //gridView.setColumnWidth(itemWidth);

        //gridView.setHorizontalSpacing(10);

        gridView.setStretchMode(GridView.NO_STRETCH);

        gridView.setNumColumns(columnsNum);

求助各位大神我该怎么改?

<LinearLayout android:layout_width="match_parent" android:orientation="horizontal" android:layout_height="wrap_content"> <ImageView android:layout_width="0dp" android:layout_height="wrap_content" android:layout_weight="1"/> <GridView android:layout_width="0dp" android:layout_height="wrap_content" android:layout_weight="3"> </GridView> </LinearLayout> 你这样写试试
