所以我一直试图将两个div并排排列而不重叠.我有一个div将固定为侧边栏,右边div作为内容.希望有人可以帮助我.

body {
  background-color: #444;
  margin-top: 0;
  margin-bottom: 0;
}

#wrapper {
  width: 1005px;
  margin: 0 auto;
  padding: 0;
  overflow: auto;
}

#leftcolumn {
  width: 250px;
  background-color: #111;
  padding: 0;
  margin: 0;
  display: block;
  border: 1px solid white;
  position: fixed;
}

#rightcolumn {
  width: 750px;
  background-color: #777;
  display: block;
  float: left;
  border: 1px solid white;
}

<div id="wrapper">
  <div id="leftcolumn">
  </div>
  <div id="rightcolumn">
  </div>
</div>

我试图从我当前的片段添加一个意图到另一个片段.为此我在卡片中的ImageButton上添加了一个OnclickListener.

但它不能正常工作,我在代码中找不到错误.

import com.example.kgb.components.UpdatedTextView;

import java.util.ArrayList;


public class MyAccountsCardAdapter extends RecyclerView.Adapter<MyAccountsCardAdapter.ViewHolder> {

    private static Context context;

    public MyAccountsCardAdapter(Context context) {
        this.context=context;
    }

    private ArrayList<MyAccountsCard>cardArrayList;
    public MyAccountsCardAdapter(ArrayList<MyAccountsCard> cardData) {
        this.cardArrayList=cardData;
    }

    @Override
    public ViewHolder onCreateViewHolder(ViewGroup parent, int viewType) {
        View itemView= LayoutInflater.from(parent.getContext()).inflate(R.layout.accounts_card_layout, parent, false);
        ImageButton imButton = (ImageButton) itemView.findViewById(R.id.shareButton);
        return new ViewHolder(itemView,imButton);
    }

    @Override
    public void onBindViewHolder(MyAccountsCardAdapter.ViewHolder …
