Question

我只是创建一个带有循环视图的对话框。然后，如何从选定的循环视图中获取值并将其设置为相同的活动

上的editext

this is the dialog and the value from recycle view

我调用对话框的代码，并为回收视图设置addOnItemTouchListener。当我运行它时，我的应用程序会强行关闭

@SuppressLint("ResourceType")
@OnClick(R.id.button_choose)
void chooseLOV() {

    AlertDialog.Builder dialogBuilder = new AlertDialog.Builder(this);
    LayoutInflater inflater = this.getLayoutInflater();
    View dialogView = inflater.inflate(R.layout.lov_kodepos, null);
    dialogBuilder.setView(dialogView);

    final RecyclerView recyclerView = (RecyclerView) dialogView.findViewById(R.id.rv_lov_kodepos);


    API.getKodePos().enqueue(new Callback<ArrayList<KodePos>>() {
        @Override
        public void onResponse(Call<ArrayList<KodePos>> call, Response<ArrayList<KodePos>> response) {
            if (response.code()== 200){
                Log.i("bella", "onResponse: "+response);

                data = response.body();
                recyclerView.setHasFixedSize(true);
                recyclerView.addItemDecoration(new DividerItemDecoration(AddCustomerActivity.this, DividerItemDecoration.VERTICAL));
                recyclerView.setLayoutManager(new LinearLayoutManager(AddCustomerActivity.this));
                recyclerView.setAdapter(new KodePosAdapter(data));
            }
        }

        @Override
        public void onFailure(Call<ArrayList<KodePos>> call, Throwable t) {
            Toast.makeText(AddCustomerActivity.this, "Failed", Toast.LENGTH_SHORT).show();

        }
    });

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

    recyclerView.addOnItemTouchListener(new RecyclerItemClickListener(AddCustomerActivity.this, new RecyclerItemClickListener.OnItemClickListener() {
        @Override
        public void onItemClick(View view, int position) {
            Intent intent = new Intent(AddCustomerActivity.this,AddCustomerActivity.class);
            intent.putExtra(DATA_KODEPOS, tempDatas.get(position).getPoscodeId());
            startActivity(intent);

            if(dataKodePos.getPoscodeId()==DATA_KODEPOS){
                API.setKodePos(getIntent().getStringExtra(DATA_KODEPOS)).enqueue(new Callback<KodePos>() {
                    @Override
                    public void onResponse(Call<KodePos> call, Response<KodePos> response) {
                        KodePos hehe = response.body();
                        et_provinsi.setText(hehe.getPosProp());
                        et_kota.setText(hehe.getPosKota());
                        et_kecamatan.setText(hehe.getPosCamat());
                        et_kelurahan.setText(hehe.getPosLurah());
                        et_kodepos.setText(hehe.getPosKode());
                    }

                    @Override
                    public void onFailure(Call<KodePos> call, Throwable t) {

                    }
                });
            }else {

            }

        }

    }));

我的适配器

 public class KodePosAdapter extends 
 RecyclerView.Adapter<KodePosAdapter.KodePosViewHolder> {

ArrayList<KodePos> datasSet;

public KodePosAdapter(ArrayList<KodePos> data) {
    this.datasSet = data;
}

@Override
public KodePosViewHolder onCreateViewHolder(ViewGroup parent, int viewType) {
    View itemView = LayoutInflater.from(parent.getContext())
            .inflate(R.layout.lov_recyclerview, parent, false);

    return new KodePosViewHolder(itemView);
}

@Override
public void onBindViewHolder(KodePosViewHolder holder, int position) {
    KodePos kdModel = datasSet.get(position);

    holder.kodePos.setText(kdModel.getPosKode());
    holder.kecamatan.setText(kdModel.getPosCamat().toLowerCase());
    holder.kelurahan.setText(kdModel.getPosLurah().toLowerCase());
}

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

public class KodePosViewHolder extends RecyclerView.ViewHolder {

    public TextView kodePos, kecamatan, kelurahan;

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

        kodePos = (TextView)itemView.findViewById(R.id.tv_lov_kodepos);
        kecamatan = (TextView)itemView.findViewById(R.id.tv_lov_kecamatan);
        kelurahan = (TextView)itemView.findViewById(R.id.tv_lov_kelurahan);

    }
}

}

Answer 1

首先，您需要创建 OnItemClickListener 并将其设置为您的recyclerView适配器，以获取所点击的项目数据。

其次，在对话框中创建一个类似的 OnRecyclerItemClickListener 。在这种情况下，您需要创建一个扩展AlertDiaglog的 CustomAlertDialog 类。

Answer 2

首先，使用OnClickListener

实现KodePosViewHolder

public class KodePosViewHolder extends RecyclerView.ViewHolder implements View.OnClickListener {

覆盖onClick并获取项目的位置

@Override
        public void onClick(View v) {
            int adapterPosition = getAdapterPosition();
        }

从此adapterPosition获取kdModel然后获取文本并在“警告”对话框中显示。

KodePos kdModel = datasSet.get(adapterPosition);

Answer 3

我刚刚解决了我的问题。这比我想象的要简单得多。点击项目后，我只需要用这种方式在编辑文本中显示值

 recyclerView.addOnItemTouchListener(new RecyclerItemClickListener(AddCustomerActivity.this, new RecyclerItemClickListener.OnItemClickListener() {
        @Override
        public void onItemClick(View view, int position) {
            et_kodepos.setText(data.get(position).getPosKode());
            et_kota.setText(data.get(position).getPosKota());
            et_provinsi.setText(data.get(position).getPosProp());
            et_kecamatan.setText(data.get(position).getPosCamat());
            et_kelurahan.setText(data.get(position).getPosLurah());
        }
    }));

从警告对话框中的recyclerview获取所选项目，并将其显示在edittext中
