NineGridView

九宫格布局，普通View实现，可像使用GridView一样设置Adapter，类似于微博的网格图片布局。

gradle引入

    compile 'com.zhqchen:ninegridview:1.1.1'

配置项

    isHeightWrap: item高度是否自适应。true: 高度自适应， false: item的宽高一致
    maxItems: 最大item数量, 默认为9
    numColumns: 网格的列数，默认为3
    verticalSpacing: 垂直方向的网格间隔
    horizontalSpacing: 水平方向的网格间隔

使用

1. 在布局中加入组件:

    <com.zhqchen.ninegrid.NineGrideView
            xmlns:app="http://schemas.android.com/apk/res-auto"
            android:id="@+id/ngv_test"
            android:layout_width="match_parent"
            android:layout_height="wrap_content"
            app:verticalSpacing="4dp"
            app:horizontalSpacing="4dp"/>

2. 设置adapter:

ngvTest.setAdapter(mAdapter);

here is the sample code

public class MyGridAdapter extends NineGrideView.NineGridAdapter<Integer> {

        public MyGridAdapter(Context context, List<Integer> itemDatas) {
            super(context, itemDatas);
        }

        @Override
        protected View initViewHolder(View convertView) {
            if(convertView == null) {
                convertView = new ImageView(context);//自定义Layout
            }
            return convertView;
        }

        @Override
        protected void bindData(View convertView, int position) {
            ((ImageView)convertView).setImageResource(itemDatas.get(position));
        }

    }

3. 在界面销毁时做必要的释放:

    @Override
    protected void onDestroy() {
        ngvTest.recycle();
        super.onDestroy();
    }

说明

使用者需继承NineGridAdapter，在自己实现的adapter中自己控制Item的布局，包括各种点击事件的监听均可自由处理。
