如何从适配器在底部工作表片段中设置TextView占位符

Question

我有一个类似的BottomSheetDialogFragment类

重命名钱包对话框

public class RenameWalletDialog extends com.google.android.material.bottomsheet.BottomSheetDialogFragment  {
EditText editTextWalletName;
@Nullable
@Override
public View onCreateView(@NonNull LayoutInflater inflater, @Nullable ViewGroup container, @Nullable Bundle savedInstanceState) {
View view = inflater.inflate(R.layout.rename_wallet_sheet, container, false);
editTextWalletName = (EditText) view.findViewById(R.id.custom_input_et);
view.findViewById(R.id.btn_confirm).setOnClickListener(new View.OnClickListener() {
@Override
public void onClick(View view) {
Toast.makeText(getContext(), "Confirm button clicked", Toast.LENGTH_SHORT).show();
}
});
view.findViewById(R.id.btn_cancel).setOnClickListener(new View.OnClickListener() {
@Override
public void onClick(View view) {
dismiss();
}
});
view.findViewById(R.id.clear_field).setOnClickListener(new View.OnClickListener() {
@Override
public void onClick(View view) {
editTextWalletName.getText().clear();
}
});
return view;
}
}

我在适配器类中创建了一个函数，就像这个

钱包适配器

@Override
public DataObjectHolder onCreateViewHolder(ViewGroup parent, int viewType) {
View view = LayoutInflater.from(mCtx).inflate(R.layout.wallet_item, parent, false);
final DataObjectHolder dataObjectHolder = new DataObjectHolder(view);
dataObjectHolder.walletoptions.setOnClickListener(new View.OnClickListener() {
@Override
public void onClick(View v) {
//                Toast.makeText(v.getContext(), "Option Click " + dataObjectHolder.getAdapterPosition(), Toast.LENGTH_SHORT).show();
//                Log.d(TAG, "position = " + dataObjectHolder.getAdapterPosition());
Context wrapper = new ContextThemeWrapper(mCtx, R.style.popupMenuStyle);
final PopupMenu popup = new PopupMenu(wrapper, v, Gravity.END);
popup.inflate(R.menu.poupup_menu);
popup.show();
popup.setOnMenuItemClickListener(new PopupMenu.OnMenuItemClickListener() {
@Override
public boolean onMenuItemClick(MenuItem item) {
switch (item.getItemId()) {
case R.id.one:
showFragmentRenameWallet();
break;
case R.id.two:
//Do operation if menu_item_two
Toast.makeText(mCtx,"You Clicked : " + item.getTitle(),Toast.LENGTH_SHORT).show();
break;
}
return false;
}
});
}
});
return dataObjectHolder;
}

@Override
public void onBindViewHolder(DataObjectHolder holder, final int position) {
DecimalFormat formatter = new DecimalFormat("#,###,###");
Double doubleBalance = (double) userWalletList.get(position).getBalance();
String numberFormatBalance = formatter.format(doubleBalance);
holder.walletname.setText(userWalletList.get(position).getWalletName());
holder.walletbalance.setText(String.valueOf( "₦ " +numberFormatBalance));
//        holder.walletid.setText(String.valueOf(userWalletList.get(position).getWalletid()));
RenameWalletDialog renameWalletFragment = new RenameWalletDialog();
renameWalletFragment.show(((FragmentActivity)mCtx).getSupportFragmentManager(), renameWalletFragment.getTag());
Bundle bundle = new Bundle();
String walletN = userWalletList.get(position).getWalletName();
bundle.putString("walletname", walletN);
renameWalletFragment.setArguments(bundle);
}

@Override
public int getItemCount() {
return userWalletList.size();
}
public interface MyClickListener {
public void onItemClick(int position, View v);
}
private void showFragmentRenameWallet(){
RenameWalletDialog renameWalletFragment = new RenameWalletDialog();
renameWalletFragment.show(((FragmentActivity)mCtx).getSupportFragmentManager(), renameWalletFragment.getTag());
}

并使用类似的功能

showFragmentRenameWallet();

我想每个人现在都对我的代码逻辑如何工作有了基本的想法

我正在努力实现；

1. 我想将底部表单的编辑文本视图设置为用户单击重命名选项的钱包名称

但我看不出通过适配器实现这一点的任何可行方法，因为它实际上不是适配器视图的一部分

有人知道怎么做吗？

注意：在我的适配器的绑定视图支架中，我得到了像这样的钱包名称

holder.walletname.setText(userWalletList.get(position).getWalletName());

Answer 1

如果您想通过捆绑包传递数据，请执行此操作

适配器内：

Bundle bundle = new Bundle()
bundle.putString(SomeKey, value you want to send)
walletFragmentObject.setArguments(bundle)

然后在片段中

String text = getArguments.getString(SomeKey)

更新：

更改您的方法，如下所示：

private void showFragmentRenameWallet(ViewHolder dataObjectHolder) {
RenameWalletDialog renameWalletFragment = new RenameWalletDialog();
Bundle bundle = new Bundle();
String walletN = userWalletList
.get(dataObjectHolder.getAdapterPosition())
.getWalletName();
bundle.putString("walletname", walletN);
renameWalletFragment.show(
((FragmentActivity) mCtx).getSupportFragmentManager(),
renameWalletFragment.getTag()
);
}

从onBindViewHolder中删除与bundle和RenameWalletDialog相关的代码。
