Recyclerview 通话联系人 Android studio

Question

我有一个 Android 应用程序，我在其中使用了显示联系人列表的 RecyclerView。现在我想要的是，在选择联系人时，拨打指定的号码。

现在它所做的只是显示联系人，但是当我单击它时它会调用它，它不会执行任何操作。我不知道如何让它标记

我尝试使用onClick() 和按钮项。但不成功

我的代码：

public class RecyclerViewAdapter extends RecyclerView.Adapter<RecyclerViewAdapter.MyViewHolder> {

    private static final String TAG = "RecyclerViewAdapter";

    Context mContext;
    List<Contact> mData;
    Dialog myDialog;
    Button button;



    public RecyclerViewAdapter(Context mContext, List<Contact> mData) {
        this.mContext = mContext;
        this.mData = mData;
    }



    @Override
    public MyViewHolder onCreateViewHolder(ViewGroup parent, int viewType) {

        View v ;
        v = LayoutInflater.from(mContext).inflate(R.layout.single_item_contact,parent,false);
        final MyViewHolder vHolder = new MyViewHolder(v);

        // Dialog ini

        myDialog = new Dialog(mContext);
        myDialog.setContentView(R.layout.dialog_contact);
        myDialog.getWindow().setBackgroundDrawable(new ColorDrawable(Color.TRANSPARENT));





        vHolder.item_contact.setOnClickListener(new View.OnClickListener() {
            @Override
            public void onClick(View v) {
               // Toast.makeText(mContext,"Text Click item : "+String.valueOf(vHolder.getAdapterPosition()),Toast.LENGTH_SHORT).show();


                TextView dialog_name_tv = (TextView) myDialog.findViewById(R.id.dialog_name_id);
                TextView dialog_phone_tv = (TextView) myDialog.findViewById(R.id.dialog_phone_id);
                ImageView dialog_contact_img = (ImageView)myDialog.findViewById(R.id.dialog_img);
                dialog_name_tv.setText(mData.get(vHolder.getAdapterPosition()).getName());
                dialog_phone_tv.setText(mData.get(vHolder.getAdapterPosition()).getPhone());
                dialog_contact_img.setImageResource(mData.get(vHolder.getAdapterPosition()).getPhoto());


                myDialog.show();
            }
        });


        return vHolder;
    }

    @Override
    public void onBindViewHolder(MyViewHolder holder, final int position) {

        holder.tv_name.setText(mData.get(position).getName());
        holder.tv_phone.setText(mData.get(position).getPhone());
        holder.img.setImageResource(mData.get(position).getPhoto());



    }

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

    public static class MyViewHolder extends RecyclerView.ViewHolder {

        private LinearLayout item_contact;
        private TextView tv_name;
        private TextView tv_phone;
        private ImageView img;

        public MyViewHolder(View itemView) {
            super(itemView);

            item_contact = (LinearLayout) itemView.findViewById(R.id.contact_item_id);
            tv_name = (TextView) itemView.findViewById(R.id.name_contact);
            tv_phone = (TextView) itemView.findViewById(R.id.phone_contact);
            img = (ImageView) itemView.findViewById(R.id.img_contact);

        }
    }
}

您需要将 setOnClickListener() 放入 OnBindViewHolder()。到目前为止，我的理解是您有 Recycler View，您希望在其中单击项目时打开一个对话框 dialog_contact，此对话框包含联系信息。打开此对话框后，您想通过单击对话框中的呼叫按钮呼叫该人。

@Override
    public void onBindViewHolder(MyViewHolder holder, final int position) {

        holder.tv_name.setText(mData.get(position).getName());
        holder.tv_phone.setText(mData.get(position).getPhone());
        holder.img.setImageResource(mData.get(position).getPhoto());

        holder.item_contact.setOnClickListener(new View.OnClickListener() {
            @Override
            public void onClick(View v) {

             myDialog = new Dialog(mContext);
             myDialog.setContentView(R.layout.dialog_contact);
             myDialog.getWindow().setBackgroundDrawable(new ColorDrawable(Color.TRANSPARENT));    

             myDialog.show();

             TextView dialog_name_tv = (TextView)myDialog.findViewById(R.id.dialog_name_id);
             Button dialog_btn_call= (Button )myDialog.findViewById(R.id.dialog_btn_call);
             TextView dialog_phone_tv = (TextView) myDialog.findViewById(R.id.dialog_phone_id);
             ImageView dialog_contact_img = (ImageView)myDialog.findViewById(R.id.dialog_img);
             dialog_name_tv.setText(mData.get(vHolder.getAdapterPosition()).getName());
             dialog_phone_tv.setText(mData.get(vHolder.getAdapterPosition()).getPhone());
             dialog_contact_img.setImageResource(mData.get(vHolder.getAdapterPosition()).getPhoto());

            dialog_btn_call.setOnClickListener(new View.OnClickListener() {
            @Override
            public void onClick(View view) {
             //Do your code here
                myDialog.dismiss();
                Intent intent = new Intent(Intent.ACTION_DIAL);
                intent.setData(Uri.parse("tel:" +mData.get(holder.getAdapterPosition()).getPhone()));
                mContext.startActivity(intent);
             }
             }); 


            }
        });


    }
