imagview我想：https://www.learn2crack.com/2016/02/recyclerview-json-parsing.htmlAndroid的改造2解析用的TextView
它的工作，假設我需要證明與textview一起imageview。如何加載圖像視圖：
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;
}
這裏是我的適配器類別：
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響應：
public class JSONResponse {
private Android[] users;
public Android[] getNames() {
return users;
}
}
請求接口：
public interface RequestInterface {
@GET("sampleJson.php")
Call<JSONResponse> getJSON();
}
這裏是我的主活動：
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());
}
});
}
}
這裏是我的row_layout：
<android.support.v7.widget.CardView
xmlns:card_view="http://schemas.android.com/apk/res-auto"
xmlns:android="http://schemas.android.com/apk/res/android"
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:layout_marginTop="5dp"
android:layout_marginLeft="5dp"
android:layout_marginRight="5dp"
card_view:cardCornerRadius="5dp">
<LinearLayout
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:layout_gravity="center"
android:orientation="horizontal">
<ImageView
android:layout_width="60dp"
android:layout_height="60dp"
android:id="@+id/img_android"
android:src="@drawable/ic_launcher"
/>
<LinearLayout
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:layout_marginLeft="10dip"
android:layout_gravity="center"
android:orientation="vertical">
<TextView
android:id="@+id/first_name"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:text="New Text"
android:textColor="#000" />
<TextView
android:id="@+id/last_name"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:text="New Text"
android:textColor="#000" />
</LinearLayout>
主要佈局：
<RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android"
xmlns:tools="http://schemas.android.com/tools"
android:layout_width="match_parent"
android:layout_height="match_parent"
tools:context="com.retro.MainActivity">
<android.support.v7.widget.RecyclerView
android:id="@+id/card_recycler_view"
android:layout_width="match_parent"
android:layout_height="match_parent"
android:scrollbars="vertical" />
我試着用畢加索：不知道，但ImageView的不加載 Picasso.with（context）.load（android_versions.get（i）.getAndroid_image_url（））。resize（120，60）.into（viewHolder.img_android）;
任何想法傢伙...請讓我知道
