**首先展示下布局頁面
**
下面展示一些 主要代碼，
RecyclerView recyclerView=(RecyclerView) findViewById(R.id.recycler_view);
//這里可以設定 頁面是垂直or水平滾動 調節最后的引數 HORIZONTAL 或 Veritcal
StaggeredGridLayoutManager layoutManager = new StaggeredGridLayoutManager(5, StaggeredGridLayoutManager.HORIZONTAL);
// GridLayoutManager layoutManager =new GridLayoutManager(this,GridLayoutManager.HORIZONTAL,30, android.R.color.black);
recyclerView.setLayoutManager(layoutManager);
FruitAdapter adapter = new FruitAdapter(fruitList);
recyclerView.setAdapter(adapter);
這里的代碼主要是創建StaggeredGridLayoutManage 實體并設參，第一個引數是設定有顯示的有幾行，把6和上面展示圖片對比，可以發現一個頁面剛好可以放6行，有興趣也可以自己試試改幾天數字，第二個引數 這里設定了水平滾動， 還有豎直滾動可以設定
new Fruit(getRandomLengthName("Grape"), R.drawable.grape_pic);
fruitList.add(grape);
Fruit pineapple = new Fruit(getRandomLengthName("Pineapple"), R.drawable.pineapple_pic);
fruitList.add(pineapple);
Fruit strawberry = new Fruit(getRandomLengthName("Strawberry"), R.drawable.strawberry_pic);
fruitList.add(strawberry);
Fruit cherry = new Fruit(getRandomLengthName("Cherry"), R.drawable.cherry_pic);
fruitList.add(cherry);
Fruit mango = new Fruit(getRandomLengthName("Mango"), R.drawable.mango_pic);
fruitList.add(mango);
}
}
private String getRandomLengthName(String name) {
Random random = new Random();
// int length = random.nextInt(20) + 1;
StringBuilder builder = new StringBuilder();
// for (int i = 0; i < length; i++) {
for (int i = 0; i < 1; i++) {
builder.append(name);
}
return builder.toString();
}
