我想在警报对话框中添加两个编辑文本字段。就像解决方案听起来一样简单，我还没有能够收集到一个有效的解决方案。我无法同时设置两个（编辑文本）视图。

如果您想查看更多代码，请发表评论。

                alertDialog.setTitle("Values");
                final EditText quantity = new EditText(SecondScan.this);
                final EditText lot = new EditText(SecondScan.this);

                quantity.setInputType(InputType.TYPE_CLASS_NUMBER | InputType.TYPE_NUMBER_FLAG_DECIMAL);
                lot.setInputType(InputType.TYPE_CLASS_NUMBER | InputType.TYPE_NUMBER_FLAG_DECIMAL);

                Project=arr[0].toString();
                Item=arr[1].toString();


                alertDialog.setMessage( "Employee No. : " + (Login.user).trim()+
                        "\nWarehouse      : " + (FirstScan.Warehouse).trim()+ 
                        "\nLocation           : " + (FirstScan.Location).trim()+ 
                        "\nProject              : " + Project.trim() + 
                        "\nItem                   : " + Item.trim() + 
                        "\nLot                      : " + Lot.trim()+  
                        "\n\nQuantity   :" );
                alertDialog.setView(quantity);
                    alertDialog.setView(lot);
 // the bit of code that doesn't seem to be working.


                alertDialog.setCancelable(false);
                alertDialog.setPositiveButton("Update",  new DialogInterface.OnClickListener() { 

                    public void onClick(DialogInterface dialog, int id) {
                        //ACTION
                    }
                });

                AlertDialog alert = alertDialog.create();
                alert.show();

我希望第一个编辑文本出现在批次之后，第二个编辑文本出现在数量之后，而当我尝试推送两个视图时，似乎只有一个在工作。

更新：事实证明，实际上没有任何方法可以将多个视图单独添加到警报对话框而无需为其创建布局。

请参阅在 android 中创建自定义布局。

alertDialog.setTitle("Values");
final EditText quantity = new EditText(SecondScan.this);
final EditText lot = new EditText(SecondScan.this);

quantity.setInputType(InputType.TYPE_CLASS_NUMBER | InputType.TYPE_NUMBER_FLAG_DECIMAL);
lot.setInputType(InputType.TYPE_CLASS_NUMBER | InputType.TYPE_NUMBER_FLAG_DECIMAL);

Project=arr[0].toString();
Item=arr[1].toString();

LinearLayout ll=new LinearLayout(this);
ll.setOrientation(LinearLayout.VERTICAL);
ll.addView(quantity);
ll.addView(lot);
alertDialog.setView(ll);

alertDialog.setCancelable(false);
alertDialog.setPositiveButton("Update",  new DialogInterface.OnClickListener() {
    public void onClick(DialogInterface dialog, int id) {
        //ACTION
    }
});

AlertDialog alert = alertDialog.create();
alert.show();

我使用 LinearLayout 作为登录弹出窗口：

public final String POPUP_LOGIN_TITLE="Sign In";
public final String POPUP_LOGIN_TEXT="Please fill in your credentials";
public final String EMAIL_HINT="--Email--";
public final String PASSWORD_HINT="--Password--";

AlertDialog.Builder alert = new AlertDialog.Builder(this);

        alert.setTitle(POPUP_LOGIN_TITLE);
        alert.setMessage(POPUP_LOGIN_TEXT);

        // Set an EditText view to get user input 
        final EditText email = new EditText(this);
        email.setHint(EMAIL_HINT);
        final EditText password = new EditText(this);
        password.setHint(PASSWORD_HINT);
        LinearLayout layout = new LinearLayout(getApplicationContext());
        layout.setOrientation(LinearLayout.VERTICAL);
        layout.addView(email);
        layout.addView(password);
        alert.setView(layout);

        alert.setPositiveButton("Ok", new DialogInterface.OnClickListener() {
        public void onClick(DialogInterface dialog, int whichButton) {

          // Do something with value!
          }
        });

        alert.setNegativeButton("Cancel", new DialogInterface.OnClickListener() {
          public void onClick(DialogInterface dialog, int whichButton) {
            // Canceled.
          }
        });

        alert.show();

您应该创建一个可以添加 EditTexts 的垂直 LinearLayout。然后将 alertDialog.setView() 与 LinearLayout 一起使用。

为什么不为它制作一个完全自定义的布局？

这是一个自定义弹出窗口，用于显示类别列表并让用户选择一个。

public class CategoryPickerFragment extends DialogFragment implements OnItemClickListener{
private CategoryReceiver receiver;
@Override
public Dialog onCreateDialog(Bundle savedInstanceState) {
    AlertDialog.Builder builder = new AlertDialog.Builder(getActivity());
    // Get the layout inflater
    LayoutInflater inflater = getActivity().getLayoutInflater();

    // Inflate and set the layout for the dialog
    // Pass null as the parent view because its going in the dialog layout
    View view = inflater.inflate(R.layout.category_picker_fragment, null);

    builder.setView(view);
    AlertDialog ad = builder.create();

    CategoryList categoryList = (CategoryList) view.findViewById(R.id.clCategories);
    categoryList.setOnItemClickListener(this);

    return ad;
}
public void setCategoryReceiver(CategoryReceiver receiver){
    this.receiver = receiver;
}

@Override
public void onItemClick(AdapterView<?> parent, View view, int position, long id) {
    Category category = ((CategoryListChild)view).getCategory();
    receiver.setCategory(category);
    this.dismiss();
}

请注意，我扩展了一个 DialogFragment，使用自定义布局覆盖 OnCreateDialog 一个 alertDialog，然后将其显示给用户。
