将图像视图设置为水平滚动视图

Question

您好，我有一个 url，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。谁能告诉我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);
    }
}

自定义图像视图

 <?xml version="1.0" encoding="utf-8"?>
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
    android:orientation="vertical"
    android:layout_width="match_parent"
    android:layout_height="match_parent">

    <ImageView
        android:id="@+id/customserverdownlodedimg"
        android:layout_width="wrap_content"

        android:src="@mipmap/ic_launcher"/>
</LinearLayout>

Answer 1

你可以这样做

 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应该看起来像这样

    <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>

Answer 2

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)

    }
}
