Ich habe versucht: https://www.learn2crack.com/2016/02/recyclerview-json-parsing.htmlAndroid Nachrüst-2-Parsing imagview mit Textview
Sein Arbeits, nehme ich an imageview zusammen mit textview zeigen müssen. Wie die Bildansicht laden:
package com.retro;
public class Android{
public String getFirstname() {
return firstname;
}
public void setFirstname(String firstname) {
this.firstname = firstname;
}
public String getLastname() {
return lastname;
}
public void setLastname(String lastname) {
this.lastname = lastname;
}
private String firstname;
private String lastname;
public String getImage() {
return image;
}
public void setImage(String image) {
image = image;
}
private String image;
}
Hier ist meine Adapter Klasse:
public class DataAdapter extends RecyclerView.Adapter<DataAdapter.ViewHolder> {
private ArrayList<Android> names;
public DataAdapter(ArrayList<Android> first) {
this.names = first;
}
@Override
public DataAdapter.ViewHolder onCreateViewHolder(ViewGroup viewGroup, int i) {
View view = LayoutInflater.from(viewGroup.getContext()).inflate(R.layout.list_item, viewGroup, false);
return new ViewHolder(view);
}
@Override
public void onBindViewHolder(DataAdapter.ViewHolder viewHolder, int i) {
viewHolder.song_title.setText(names.get(i).getFirstname());
viewHolder.song_year.setText(names.get(i).getLastname());
}
@Override
public int getItemCount() {
return names.size();
}
public class ViewHolder extends RecyclerView.ViewHolder{
public TextView song_title, song_year, song_author;
public ImageView Image;
public ViewHolder(View view) {
super(view);
song_title = (TextView) view.findViewById(R.id.first_name);
song_year = (TextView) view.findViewById(R.id.last_name);
Image=(ImageView) view.findViewById(R.id.img_android);
}
}
}
Json Antwort:
public class JSONResponse {
private Android[] users;
public Android[] getNames() {
return users;
}
}
Anfrage Schnittstelle:
public interface RequestInterface {
@GET("sampleJson.php")
Call<JSONResponse> getJSON();
}
Hier ist mein HauptAktivität:
public class MainActivity extends AppCompatActivity {
private RecyclerView recyclerView;
private ArrayList<Android> data;
private DataAdapter adapter;
@Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);
initViews();
}
private void initViews(){
recyclerView = (RecyclerView)findViewById(R.id.card_recycler_view);
recyclerView.setHasFixedSize(true);
RecyclerView.LayoutManager layoutManager = new LinearLayoutManager(getApplicationContext());
recyclerView.setLayoutManager(layoutManager);
loadJSON();
}
private void loadJSON(){
Retrofit retrofit = new Retrofit.Builder()
.baseUrl("URRRRRRRRRRRLLLLL")
.addConverterFactory(GsonConverterFactory.create())
.build();
RequestInterface request = retrofit.create(RequestInterface.class);
Call<JSONResponse> call = request.getJSON();
call.enqueue(new Callback<JSONResponse>() {
@Override
public void onResponse(Call<JSONResponse> call, Response<JSONResponse> response) {
JSONResponse jsonResponse = response.body();
data = new ArrayList<>(Arrays.asList(jsonResponse.getNames()));
adapter = new DataAdapter(data);
recyclerView.setAdapter(adapter);
}
@Override
public void onFailure(Call<JSONResponse> call, Throwable t) {
Log.d("Error",t.getMessage());
}
});
}
}
Hier ist meine row_layout:

Ich habe versucht, picasso mit: Nicht sicher aber nichtImageview LadenPicasso.mit (Kontext) .load (android_versions.get (i) .getAndroid_image_url()). Resize (120, 60) .into (viewHolder.img_android);
