我在布局中有一個卡片視圖，它有兩個文本視圖和一個圖像視圖，我有一個使用卡片視圖設置項目的回收器視圖。我想要實現的是在點擊 Card View 時啟動 Bottom Sheet這是主要活動中的代碼列表代碼List<Item> lstItem; lstItem = new ArrayList<>(); lstItem.add(new Item("Samsung","Smartphones","QualitlstItem = new ArrayList<>();y Samsung Smartphones",R.drawable.samsung,"21000")); lstItem.add(new Item("Lenovo","Smartphones","Quality Lenovo smartphones",R.drawable.lenovo,"15000"));將 Recycler View Adapter 附加到 Main Activity 的代碼 FragmentManager fragmentManager = getSupportFragmentManager(); RecyclerViewAdapter2 mainAdapter2 = new RecyclerViewAdapter2(lstItem,fragmentManager); mainRecyclerView.setLayoutManager(new GridLayoutManager(this,3)); mainRecyclerView.setAdapter(mainAdapter2);Recycler View Adapter 2代碼 import android.content.Context; import android.view.LayoutInflater; import android.view.View; import android.view.ViewGroup; import android.widget.ImageView; import android.widget.TextView; import androidx.cardview.widget.CardView; import androidx.fragment.app.FragmentManager; import androidx.recyclerview.widget.RecyclerView; import java.util.List; public class RecyclerViewAdapter2 extends RecyclerView.Adapter<RecyclerViewAdapter2.MyViewHolder> { private Context context; private List<Item> data; private FragmentManager fragmentManager; public RecyclerViewAdapter2(List<Item> data, FragmentManager fragmentManager) { this.data = data; this.fragmentManager = fragmentManager; } @Override public MyViewHolder onCreateViewHolder(ViewGroup parent, int viewType) { View view = LayoutInflater.from(parent.getContext()).inflate(R.layout.cardview_items, parent, false); return new MyViewHolder(view); }}

在您的 onClick 偵聽器中，您需要使用fragmentManager傳遞給適配器的 。相反，你使用getSupportFragmentManager(). 更改后它對我有用。
holder.cardView.setOnClickListener(new View.OnClickListener() {
@Override
public void onClick(View v) {
BottomSheetFragment bottomSheetFragment = new BottomSheetFragment();
// <-- Here change getSupportFragmentManager() to fragmentManager
bottomSheetFragment.show(fragmentManager, bottomSheetFragment.getTag());
}
});

從 RecyclerView.Adapter 調用 BottomSheetDialog 片段。試試這個對我來說效果很好。
DialogFragment bottomSheetDialogFragment = new BottomsheetDialog();
bottomSheetDialogFragment.show(((FragmentActivity)mContext).getSupportFragmentManager(), bottomSheetDialogFragment.getTag());

你不能這樣做：
AppCompatActivity appCompatActivity = new AppCompatActivity();
FragmentManager fragmentManager = appCompatActivity.getSupportFragmentManager();
BottomSheetFragment bottomSheetFragment = new BottomSheetFragment();
bottomSheetFragment.show(fragmentManager, bottomSheetFragment.getTag());
您應該創建一個包含您的 BottomSheetFragment 的新活動（一個新類），并使用意圖啟動該活動。
