最近碰上需求Gridview子项目平分屏幕宽度，子项目为正方形。简单实现如下：

假设需要一行3个子item，显示为正方形：

<GridView    android:id="@+id/g1"    android:layout_width="match_parent"    android:layout_height="match_parent"    android:numColumns="3"    ></GridView>

private int a1 = 0;@Overridepublic void onWindowFocusChanged(boolean hasFocus) {    super.onWindowFocusChanged(hasFocus);    a1 = getWindowManager().getDefaultDisplay().getWidth() / 3;}

<LinearLayout    android:id="@+id/r1"    android:layout_width="match_parent"    android:layout_height="match_parent"    android:orientation="horizontal"    android:padding="5dp">    <ImageView        android:id="@+id/i1"        android:layout_width="match_parent"        android:layout_height="match_parent"        android:scaleType="centerCrop"        /></LinearLayout>

mViewHolder.mRelativeLayout = (LinearLayout) convertView.findViewById(R.id.r1);LinearLayout.LayoutParams layoutParams = new LinearLayout.LayoutParams(a1, a1);mViewHolder.mRelativeLayout.setLayoutParams(layoutParams);convertView.setTag(mViewHolder);
