select android 警报对话框中的多复选框下拉复选框

Question

我正在尝试在像微调器这样的警报对话框中提醒多选下拉复选框，但我的 android 应用程序中有复选框，有人可以帮忙吗？

Answer 1

它可能无法正常处理触摸事件。我想您将不得不克隆它并开发类似 MultiSelectSpinner 的东西。您可能想咨询 this 答案以获取更多详细信息。

Answer 2

使用 api、dialog.setconteView() 方法在 AlertDialog class 中使用自定义布局。您可以在自定义布局中添加任何您想要的小部件

Answer 3

使用下面的代码：-

AlertDialog.Builder builder = new AlertDialog.Builder(
                context);
        builder.setTitle("Title");
        builder.setMultiChoiceItems(list, null,
                new DialogInterface.OnMultiChoiceClickListener() {
                    @Override
                    public void onClick(DialogInterface dialog,
                            int indexSelected, boolean isChecked)
                    {


                    }
                })
                .setPositiveButton("OK",
                        new DialogInterface.OnClickListener() 
                {
                            @Override
                            public void onClick(DialogInterface dialog,
                                    int id) 
                            {

                            }
                        })
                .setNegativeButton("Cancel",
                        new DialogInterface.OnClickListener() {
                            @Override
                            public void onClick(DialogInterface dialog,
                                    int id) 
                            {
                            }
                        });
        dialog = builder.create();
        dialog.show();

Answer 4

按照您的看法，无法获取AlertDialog中的点击事件。

您问题的最佳解决方案。只需包含自定义布局并在 activity.

中获取 Alertdialog Click 事件

创建您要设计的 XML 布局
通过 SetContentView()
通过你的activity获取点击事件。

快乐编码:)

for Custom checkbox dropdown Dialogbox first we need to create MultiCheckAdaptar

public class MultiCheckAdaptar extends RecyclerView.Adapter<MultiCheckAdaptar.MyViewHolder>  {
    protected Context context;
    private LayoutInflater inflater;
    private ArrayList<ModelSpacialization> joblist   ;
    private String TYPE = "";
    private int count = 0 ;
    MultiCheckAdaptar.OnItemClickListener listener;

    public interface OnItemClickListener {
        void onClick(ModelSpacialization jobs, int pos , boolean type);
    }

    public MultiCheckAdaptar(Context context, ArrayList<ModelSpacialization> list, MultiCheckAdaptar.OnItemClickListener listener) {
        this.context = context;
        this.listener = listener;
        if (context != null) {
            inflater = LayoutInflater.from(context);
            this.joblist= new ArrayList<>();
            this.joblist.addAll(list);

         }
    }

    public MultiCheckAdaptar.MyViewHolder onCreateViewHolder(@NonNull ViewGroup parent, int viewType) {
        View view = inflater.inflate(R.layout.layout_ckeck_item , parent, false);
        MultiCheckAdaptar.MyViewHolder holder = new MultiCheckAdaptar.MyViewHolder(view);
        return holder;
    }

    @Override
    public int getItemViewType(int position) {
        return position;
    }


    @Override
    public void onBindViewHolder(@NonNull final MultiCheckAdaptar.MyViewHolder holder, final int position) {
        ModelSpacialization item = joblist.get(position);
        holder.txt_item.setText(item.getName());

        if(item.isCheck())
           holder.txt_item.setChecked(true) ;
         else
            holder.txt_item.setChecked(false) ;

        holder.txt_item.setOnCheckedChangeListener(new CompoundButton.OnCheckedChangeListener() {
            @Override
            public void onCheckedChanged(CompoundButton buttonView, boolean isChecked) {
                   listener.onClick(item, position, false);
                }
        });
    }

    @Override
    public int getItemCount() {
        return joblist.size();
    }

    class MyViewHolder extends RecyclerView.ViewHolder {
       CheckBox txt_item ;
          public MyViewHolder(View itemView) {
            super(itemView);
              txt_item = itemView.findViewById(R.id.txt_item);

        }

    }
