您好我有一个网址，它给了我2个图片链接。我必须下载图像并设置图像。我正在使用水平滚动视图，直到获取图像URL并使用异步任务下载图像。有人可以让我知道如何将图像设置为水平滚动视图。
public void fetchImageUrl(){
String url="http://apps.aspelec.com/cms/api/UploadImageAndChangeComplaintStatus?companyid=1&callrecordid=13";
StringRequest request=new StringRequest(Request.Method.GET, url, new Response.Listener<String>() {
@Override
public void onResponse(String response) {
System.out.println(response);
getJsonUrl(response);
}
}, new Response.ErrorListener() {
@Override
public void onErrorResponse(VolleyError error) {
Log.e("ErrorListner=",error.getMessage());
}
});
RequestQueue requestQueue = Volley.newRequestQueue(this);
requestQueue.add(request);
}
public void getJsonUrl(String response){
try {
JSONArray jArray = new JSONArray(response);
ArrayList<String> imgurl=new ArrayList<>();
for(int i=0;i<1;i++){
String dummyurl=jArray.getJSONObject(i).getString("ImagePath");
System.out.println("dummy url=="+dummyurl);
imgurl.add(dummyurl);
setView(imgurl);
}
}catch (JSONException e){
}
}
public void setView(ArrayList<String> imgUrl){
for(int j=0;j<imgUrl.size();j++){
vi=(LayoutInflater)getApplicationContext().getSystemService(Context.LAYOUT_INFLATER_SERVICE);
v=vi.inflate(R.layout.custome_serverdownloadedimageview,null,false);
img=(ImageView)v.findViewById(R.id.customserverdownlodedimg);
new DownloadImage(img).execute(imgUrl.get(j));
//Picasso.with(this).load(imgUrl.get(j)).resize(100,100).into(img);
}
}

你可以做这样的事情
horizontalScrollView = (HorizontalScrollView)findViewById(R.id.horizontal_grid);
int[] images = new int[]{R.drawable.image1, R.drawable.image2, ....R.drawable.image10};
LinearLayout sv = (LinearLayout) findViewById (R.id.horizontal_container);
for (int i=0 ; i<images.length; i++){
ImageView iv = new ImageView (this);
LinearLayout.LayoutParams imageViewLayoutParams = new LinearLayout.LayoutParams(ViewGroup.LayoutParams.MATCH_PARENT, ViewGroup.LayoutParams.MATCH_PARENT);
iv.setPadding(4,0,0,0);
iv.setImageResource(images[i]);
iv.setLayoutParams(imageViewLayoutParams);
sv.addView(iv);
}
你的xml看起来应该是这样的
<HorizontalScrollView
android:id="@+id/horizontal_grid"
android:layout_width="wrap_content"
android:layout_height="0dp"
android:layout_weight="40">
<LinearLayout
android:id="@+id/horizontal_container"
android:layout_width="match_parent"
android:layout_height="match_parent"
android:orientation="horizontal" >
</LinearLayout>
</HorizontalScrollView>

public void setView(ArrayList<String> imgUrl){
serverDownloadedImageView = (LinearLayout)findViewById(R.id.serverDownloadedImageView);
serverDownloadedImageView.removeAllViews();
for(int j=0;j<imgUrl.size();j++){
ImageView img = new ImageView(this);
new DownloadImage(img).execute(imgUrl.get(j));
//Picasso.with(this).load(imgUrl.get(j)).resize(100,100).into(img);
serverDownloadedImageView.addView(img,j)
}
}
