android-如何通过java给gridview之间的空间

我如何在gridView项之间实现完美对齐,我已经使用Java添加了gridview,并且设置了基本适配器,在其中添加了图像和textview.

Xml代码：

    <android.support.v7.widget.CardView 
        android:layout_width="180dp"
        android:layout_height="200dp"
        android:layout_margin="5dp"
        android:orientation="vertical"
        app:cardCornerRadius="5dp"
        app:cardElevation="5dp">

 <LinearLayout
            android:layout_width="match_parent"
            android:layout_height="match_parent"
            android:orientation="vertical">

            <LinearLayout
                android:layout_width="match_parent"
                android:layout_height="match_parent"
                android:layout_weight="1"
                android:orientation="vertical">

                <ImageView
                    android:id="@+id/ImageWomenItem"
                    android:layout_width="match_parent"
                    android:layout_height="match_parent"
                    android:clickable="true"
                    android:scaleType="fitXY"
                    android:src="@drawable/womenone" />
            </LinearLayout>


                <TextView
                    android:id="@+id/itemName"
                    android:layout_width="wrap_content"
                    android:layout_height="wrap_content"
                    android:text="Red Top"
                    android:textColor="#8e8d8d"
                    android:textSize="15dp" />

        </LinearLayout>

    </android.support.v7.widget.CardView>

这是活动代码,在其中我声明了recylerview并将其设置为适配器

Java代码：

recyclerView = (RecyclerView) view.findViewById(R.id.recyclerViewClothes);
        recyclerView.setHasFixedSize(true);
             mLayoutManager = new GridLayoutManager(getActivity(), 2);
        recyclerView.setLayoutManager(mLayoutManager);

        mAdapter = new GridAdapter();
        recyclerView.setAdapter(mAdapter);

解决方法:

将填充添加到适配器xml的根布局中.

<LinearLayout     
android:layout_width="match_parent"
android:layout_height="match_parent"
android:orientation="vertical"
android:padding="8dp">

<android.support.v7.widget.CardView
    app:cardCornerRadius="5dp"
    app:cardElevation="5dp"
    android:layout_width="180dp"
    android:layout_height="200dp"
    android:layout_margin="5dp"
    android:orientation="vertical">.......
</android.support.v7.widget.CardView>

 </LinearLayout>
