感謝Chris在這個google groups answer,我使用GridLayoutManager而不是StaggeredGridLayoutManager解決了這個問題。
這裏是解決方案
public static final int ITEMS_PER_AD = 8;
private GridLayoutManager mLayoutManager;
// The Native Express ad height.
private static final int NATIVE_EXPRESS_AD_HEIGHT = 150;
// The Native Express ad unit ID.
private static final String AD_UNIT_ID = "ca-app-pub-3940256099942544/1072772517";
// The RecyclerView that holds and displays Native Express ads and menu items.
private RecyclerView mRecyclerView;
// List of Native Express ads and MenuItems that populate the RecyclerView.
private List<Object> mRecyclerViewItems = new ArrayList<>();
@Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);
mLayoutManager = new GridLayoutManager(this, 2);
mLayoutManager.setSpanSizeLookup(new
GridLayoutManager.SpanSizeLookup() {
@Override
public int getSpanSize(int position) {
if (position % MainActivity.ITEMS_PER_AD == 0) {
return 2;
}
return 1;
}
});
mRecyclerView = (RecyclerView) findViewById(R.id.recycler_view);
// Use this setting to improve performance if you know that changes
// in content do not change the layout size of the RecyclerView.
mRecyclerView.setHasFixedSize(true);
// Specify a linear layout manager.
mRecyclerView.setLayoutManager(mLayoutManager);
// Update the RecyclerView item's list with menu items and Native Express ads.
addMenuItemsFromJson();
addNativeExpressAds();
setUpAndLoadNativeExpressAds();
// Specify an adapter.
RecyclerView.Adapter adapter = new RecyclerViewAdapter(this, mRecyclerViewItems);
mRecyclerView.setAdapter(adapter);
}
如果你能按照this sample project,你可以找到其他類和佈局。因爲這是這個項目的修改版本。 我希望這個解決方案能夠像我這樣的人工作。
