我有一个 recyclerview，我将其设置为具有两列的 gridview。我为 recyclerview 适配器设置了一个 cardview 自定义。现在我的 gridview 不是 wrap_content，其值在 cardview 并且所有项目都具有相同的大小。
我怎样才能用 cardview 的内容包裹 gridview 的高度？
private void getuserposts() {
StringRequest request = new StringRequest(
Config.GET_POST_USER,
new Response.Listener<String>() {
@Override
public void onResponse(String s) {
posts = Config.Jsonparserpostuser(s);
if(posts.size() != 0){
adapter = new PostsAdapterProfile(posts,activity.getApplicationContext());
RecyclerView.LayoutManager layoutManager = new GridLayoutManager(activity.getApplicationContext(),2);
recyclerView.setLayoutManager(layoutManager);
recyclerView.setAdapter(adapter);
} else if(posts.size() == 0){
noresult.setVisibility(View.VISIBLE);
noresult.setImageResource(R.drawable.noresult);
}
}
}, new Response.ErrorListener() {
@Override
public void onErrorResponse(VolleyError volleyError) {
VolleyLog.d("Profile Error ", "Error is " + error.getMessage());
}
}){
@Override
protected Map<String, String> getParams() throws AuthFailureError {
Map<String,String> param = new HashMap<>();
param.put("email",email);
return param;
}
};
RequestQueue queue = Volley.newRequestQueue(activity.getApplicationContext());
queue.add(request);
}

最佳答案
只需使用 StaggeredGridLayoutManager 而不是 GridLayoutManager
StaggeredGridLayoutManager staggeredGridLayoutManager = new StaggeredGridLayoutManager(2, StaggeredGridLayoutManager.VERTICAL);
recyclerView.setLayoutManager(staggeredGridLayoutManager);
