如何将不同 api id 的数据显示到 recyclerview 的不同项目？
how to display data of different api ids to different items of recycle view?
我将简要地写下我真正想要的东西以及我的确切位置 stucked.I正在使用改造从 api 加载回收视图中的列表（我已成功加载）请参阅此图片- ->image description here.
此外，我有两个 api ID（例如：https//..id=1 和 https//..id=2 等等，具体取决于此列表 image description here。）
这是我的 2 apis:(第一个 https//..id=1)

正如您在 apis 中看到的那样，单击项目时应该将它们各自的描述从 apis 加载到下一个 activity像这样-->image description here
如果你想要我可以分享code.just告诉你你到底需要什么。我会编辑
这是我的下一个activity适配器代码：
public class NextAndroidAdapter extends RecyclerView.Adapter<NextAndroidAdapter.CustomViewHolder> {
DescriptionModel WAmdel;
Context context;
public NextAndroidAdapter(Context context,DescriptionModel employees) {
this.WAmdel = employees;
this.context=context;
}
@Override
public CustomViewHolder onCreateViewHolder(ViewGroup parent, int viewType) {
View itemView = LayoutInflater.from(parent.getContext())
.inflate(R.layout.nextwhatsandroid_item , parent, false);
return new CustomViewHolder(itemView);
}
@Override
public void onBindViewHolder(CustomViewHolder holder, final int position) {
// holder.textView.setText(String.valueOf(position+1)+". ");
holder.textView.setText(WAmdel.getDescription());
}
@Override
public int getItemCount() {
return 1;
}
public class CustomViewHolder extends RecyclerView.ViewHolder {
TextView textView;
public CustomViewHolder(View view) {
super(view);
// employeeName = (TextView) view.findViewById(R.id.WA2);
textView=view.findViewById(R.id.detailswhatsandroid);
}
});
}
}
}
这是我的回收视图项目适配器（image description here）：
public class WhatsAndroidAdapter extends RecyclerView.Adapter<WhatsAndroidAdapter.CustomViewHolder> {
List<WhatsAndroid.WhatsAndroidModel> WAmdel;
Context context;
public WhatsAndroidAdapter(Context context,List<WhatsAndroid.WhatsAndroidModel> employees) {
this.WAmdel = employees;
this.context=context;
}
@Override
public CustomViewHolder onCreateViewHolder(ViewGroup parent, int viewType) {
View itemView = LayoutInflater.from(parent.getContext())
.inflate(R.layout.whatsandroid_item , parent, false);
return new CustomViewHolder(itemView);
}
@Override
public void onBindViewHolder(CustomViewHolder holder, final int position) {
holder.textView.setText(String.valueOf(position+1)+". ");
holder.employeeName.setText(WAmdel.get(position).getTitle());
}
@Override
public int getItemCount() {
return WAmdel.size();
}
public class CustomViewHolder extends RecyclerView.ViewHolder {
public TextView employeeName;
TextView textView;
public CustomViewHolder(View view) {
super(view);
employeeName = (TextView) view.findViewById(R.id.WA2);
textView=view.findViewById(R.id.WA1);
view.setOnClickListener(new View.OnClickListener() {
@Override
public void onClick(View v) {
Intent intent = new Intent(context, NextActivity.class);
intent.setFlags(Intent.FLAG_ACTIVITY_NEW_TASK);
intent.putExtra("title", WAmdel.get(getAdapterPosition()).getTitle());
context.startActivity(intent);
}
});
}
}
}
下一个activity:
public class NextActivity extends AppCompatActivity {
private RecyclerView recyclerView;
private NextAndroidAdapter adapter;
private DescriptionModel DescriptList;
@Override
protected void onCreate(@Nullable Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.nextwhatsandroid_layout);
Toolbar toolbar = (Toolbar) findViewById(R.id. toolbar );
setSupportActionBar( toolbar );
if (getSupportActionBar() != null) {
getSupportActionBar().setDisplayHomeAsUpEnabled(true);
getSupportActionBar().setDisplayShowHomeEnabled(true);
}
Intent intent = getIntent();
String title = intent.getStringExtra("title");
String hello=intent.getStringExtra("hii");
getSupportActionBar().setTitle(title);
/*Create handle for the RetrofitInstance interface*/
DescriptService service = DescriptClientInstance.getRetrofitInstance().create(DescriptService.class);
Call<DescriptionModel> call = service.getAllPhotos();
call.enqueue(new Callback<DescriptionModel>() {
@Override
public void onResponse(Call<DescriptionModel> call, Response<DescriptionModel> response) {
// progressDialog.dismiss();
DescriptList=response.body();
generateDataList(DescriptList);
}
@Override
public void onFailure(Call<DescriptionModel> call, Throwable t) {
// progressDialog.dismiss();
Toast.makeText(getApplicationContext(), "Something went wrong...Please try later!", Toast.LENGTH_SHORT).show();
}
});
}
private void generateDataList(DescriptionModel photoList) {
recyclerView = findViewById(R.id.recyclenext);
LinearLayoutManager manager = new LinearLayoutManager(getApplicationContext());
recyclerView.setLayoutManager(manager);
recyclerView.setHasFixedSize(true);
adapter = new NextAndroidAdapter(getApplicationContext(),photoList);
recyclerView.setAdapter(adapter);
}
@Override
public boolean onOptionsItemSelected(@NonNull MenuItem item) {
if (item.getItemId() ==android.R.id.home) {
finish();
}
return super.onOptionsItemSelected(item);
}
@Override
public void onBackPressed() {
super.onBackPressed();
}
}
但现在我是这样出来的：
当我点击 item0 它进入下一个屏幕并显示 item1 的描述但是当我点击 item1 它进入下一个屏幕显示与之前相同的描述..我应该在改造界面方法中做什么？
需要帮助...提前致谢
在 Adapter 中，在 Binding 方法上添加 item click listener 并在 position base 上发送描述，并在 intent 中或通过参数传递描述，如下所示：
holder.itemView.setonClickListener(new OnItemClickListner{
override
onClick(View view){
intent i=new Intent(context,YOUR_ACTIVITY);
i.putString("description",you_data_list.get(postion)
.getString("description");
context.startActivity(i);
}
}
据我了解你想做什么，据此我假设你需要进行以下更改：
在WhatsAndroidAdapter
view.setOnClickListener(new View.OnClickListener() {
@Override
public void onClick(View v) {
Intent intent = new Intent(context, NextActivity.class);
intent.setFlags(Intent.FLAG_ACTIVITY_NEW_TASK);
intent.putExtra("title", WAmdel.get(getAdapterPosition()).getTitle());
intent.putExtra("id", WAmdel.get(getAdapterPosition()).getId());
context.startActivity(intent);
}
});
在NextActivity
Intent intent = getIntent();
String title = intent.getStringExtra("title");
String id = intent.getStringExtra("id");
String hello=intent.getStringExtra("hii");
getSupportActionBar().setTitle(title);
/*Create handle for the RetrofitInstance interface*/
DescriptService service = DescriptClientInstance.getRetrofitInstance().create(DescriptService.class);
Call<DescriptionModel> call = service.getAllPhotos(id);
call.enqueue(new Callback<DescriptionModel>() {
@Override
public void onResponse(Call<DescriptionModel> call, Response<DescriptionModel> response) {
// progressDialog.dismiss();
DescriptList=response.body();
generateDataList(DescriptList);
}
@Override
public void onFailure(Call<DescriptionModel> call, Throwable t) {
// progressDialog.dismiss();
Toast.makeText(getApplicationContext(), "Something went wrong...Please try later!", Toast.LENGTH_SHORT).show();
}
});
在DescriptService
@GET("/v1/android_tutorials/single_tutorial")
Call<DescriptionModel> getAllPhotos(@Query("tutorial_id") String id);
