Question

我是android的新手，并尝试编码来显示从API获取的海报，问题是在运行之后然后它只显示一张海报。请给我一些建议

1.poster_image.xml

<ImageView xmlns:android="http://schemas.android.com/apk/res/android"
android:id="@+id/poster"
android:layout_width="500dp"
android:layout_height="60dp" />

2.MainActivity.java

public class MainActivity extends AppCompatActivity {

ArrayList<String> moviesList = new ArrayList<>();
ImageView mImageView;
String url = "https://api.themoviedb.org/3/movie/popular?api_key=(MY API KEY)";
String image_url = "http://image.tmdb.org/t/p/w185";

@Override
protected void onCreate(Bundle savedInstanceState) {
    super.onCreate(savedInstanceState);
    setContentView(R.layout.poster_image);


   mImageView = (ImageView) findViewById(R.id.poster);

    // Fetch Data from API
    RequestQueue requestQueue = Volley.newRequestQueue(this);

    JsonObjectRequest jsonObjectRequest = new JsonObjectRequest(Request.Method.GET, url, null,
            new Response.Listener<JSONObject>() {

                @Override
                public void onResponse(JSONObject response) {
                    try {
                        JSONArray jsonArray = response.getJSONArray("results");

                        for (int i = 0; i < jsonArray.length(); i++) {
                            JSONObject movies = jsonArray.getJSONObject(i);

                            String poster = movies.getString("poster_path");


                            moviesList.add(poster);
                            Log.i("IS", String.valueOf(moviesList));
                        }


                        for (int j = 0; j < moviesList.size(); j++) {
                            Picasso.with(getApplicationContext())
                                    .load(image_url + moviesList.get(j))
                                    .into(mImageView);

                            Log.i("I", image_url + moviesList.get(j));
                        }

                    } catch (JSONException e) {
                        e.printStackTrace();
                    }
                }
            },
            new Response.ErrorListener() {

                @Override
                public void onErrorResponse(VolleyError error) {
                    Log.e("Error", "Wrong");
                }
            });

    requestQueue.add(jsonObjectRequest);
}
}
