问题描述
我有，我想一些图片在一排与水平滚动选项显示的要求。
我试图把一个gridview一个水平滚动视图里面，设置GridView控件对图像的数量列数。但是，这也是没有办法。
请提出好的建议？

解决方案
我有没有使用任何图书馆终于实现了，看看这个：
我收到了JSON的反响是这样的：
<$p$p><$c$c>{"searchInfo":{"status":"1","message":"Success","clist":[{"id":"1de57434-795e-49ac-0ca3-5614dacecbd4","name":"Theater","image_url":"http://52.25.198.71/miisecretory/category_images/movie.png"},{"id":"62fe1c92-2192-2ebb-7e92-5614dacad69b","name":"CNG","image_url":"http://52.25.198.71/miisecretory/category_images/cng.png"},{"id":"8060094c-df4f-5290-7983-5614dad31677","name":"Wine-shop","image_url":"http://52.25.198.71/miisecretory/category_images/beer.png"},{"id":"888a90c4-a6b0-c2e2-6b3c-561788e973f6","name":"Chemist","image_url":"http://52.25.198.71/miisecretory/category_images/chemist.png"},{"id":"a39b4ec1-943f-b800-a671-561789a57871","name":"Food","image_url":"http://52.25.198.71/miisecretory/category_images/food.png"},{"id":"c644cc53-2fce-8cbe-0715-5614da9c765f","name":"College","image_url":"http://52.25.198.71/miisecretory/category_images/college.png"},{"id":"c71e8757-072b-1bf4-5b25-5614d980ef15","name":"Hospital","image_url":"http://52.25.198.71/miisecretory/category_images/hospital.png"},{"id":"db835491-d1d2-5467-a1a1-5614d9963c94","name":"Petrol-Pumps","image_url":"http://52.25.198.71/miisecretory/category_images/petrol.png"},{"id":"f13100ca-4052-c0f4-863a-5614d9631afb","name":"ATM","image_url":"http://52.25.198.71/miisecretory/category_images/atm.png"}]}}所以我想创造一个水平滚动视图与合作点击事件，因为我也有借鉴谷歌地图路线的话，首先我画一个布局，作为这样的：
＆LT; XML版本=1.0编码=UTF-8＆GT？;
＆LT; LinearLayout中的xmlns：机器人=http://schemas.android.com/apk/res/android
机器人：layout_width =match_parent
机器人：layout_height =match_parent
机器人：方向=垂直
机器人：weightSum =5＆GT;
＆LT;片段
机器人：ID =@ + ID /图
机器人：名称=com.google.android.gms.maps.SupportMapFragment
机器人：layout_width =match_parent
机器人：layout_height =0dp
机器人：layout_weight =4/＆GT;
＆LT; HorizontalScrollView
机器人：ID =@ + ID / horizontalScroll
机器人：layout_width =match_parent
机器人：layout_height =0dp
机器人：layout_weight =1＆GT;
＆LT;的LinearLayout
机器人：ID =@ + ID / LL
机器人：layout_width =match_parent
机器人：layout_height =match_parent
机器人：重力=中心
机器人：方向=横向＆GT;
＆LT; / LinearLayout中＆GT;
＆LT; / HorizontalScrollView＆GT;
＆LT; / LinearLayout中＆GT;
现在根据JSON响应它由JSON数组我做到了这一点
的（INT V = 0; V＆LT; collectionInfo.size（）; v ++）{
/ * ---------------创建框架布局---------------------- * /
的FrameLayout的FrameLayout =新的FrameLayout（ActivityMap.this）;
LinearLayout.LayoutParams的LayoutParams =新LinearLayout.LayoutParams（FrameLayout.LayoutParams.WRAP_CONTENT，getPixelsToDP（90））;
layoutParams.rightMargin = getPixelsToDP（10）;
frameLayout.setLayoutParams（的LayoutParams）;
/ * --------------的框架布局年底---------------------------- * /
/ * ---------------创建图像视图---------------------- * /
最后ImageView的imgView =新ImageView的（ActivityMap.this）; //动态创建的ImageView
LinearLayout.LayoutParams lpImage =新LinearLayout.LayoutParams（LinearLayout.LayoutParams.WRAP_CONTENT，LinearLayout.LayoutParams.WRAP_CONTENT）;
imgView.setImageBitmap（collectionInfo.get（ⅴ）.getCatImage（））;
imgView.setLayoutParams（lpImage）;
//设置ID检索在稍后的时间（同它的位置）
imgView.setId（五）;
imgView.setOnClickListener（新View.OnClickListener（）{
@覆盖
公共无效的onClick（视图v）{
//长ID = imgView.getId（）;
//获取ID，这是与它的位置
Log.i（TAG，点击+ collectionInfo.get（v.getId（））getCatName（））;
//获得所选类别的数据表
新GetSelectedCategoryData（）执行（collectionInfo.get（v.getId（））getCatID（））;
}
}）;
/ * --------------图像视图结束---------------------------- * /
/ * ---------------创建文本视图---------------------- * /
TextView中的TextView =新的TextView（ActivityMap.this）; //动态创建的TextView
textView.setText（collectionInfo.get（ⅴ）.getCatName（））;
FrameLayout.LayoutParams lpText =新FrameLayout.LayoutParams（FrameLayout.LayoutParams.WRAP_CONTENT，FrameLayout.LayoutParams.WRAP_CONTENT，Gravity.BOTTOM | Gravity.CENTER）;
//注：LinearLayout.LayoutParams的引力是行不通的，所以我推的FrameLayout为3 paramater是自身重力
//lpText.gravity = Gravity.BOTTOM | Gravity.CENTER;
textView.setTextColor（Color.parseColor（＃43A047））;
textView.setLayoutParams（lpText）;
/ * --------------的文字年底---------------------------- * /
//添加的意见在适当的地方
frameLayout.addView（imgView）;
frameLayout.addView（TextView的）;
linearLayout.addView（的FrameLayout）;
}
这是在这里工作的伎俩是，我分配到的ImageView id为imgView.setId（五），之后将onClickListener来，我再获取视图的ID ......
在这样，我已经成功地实现了解决方案...我已经开发了这个code几天就回来了，我想我应该和大家一起分享....快乐编码...
I have a requirement in which I want few images to be shown in one row with horizontal scroll option.
I tried putting a gridview inside a horizontal-scrollview, and setting the number for columns of gridview to number of images.But this approach does not help.
Please suggest something?
<?xml version="1.0" encoding="utf-8"?>
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:layout_width="match_parent" android:layout_height="match_parent"
android:orientation="vertical" android:background="@android:color/white" android:clickable="true"
>
<HorizontalScrollView
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:scrollbars="none"
android:layout_margin="1dp"
android:fillViewport="false"
android:layout_below="@+id/tvHis">
<LinearLayout
android:orientation="horizontal"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
>
<GridView
android:layout_width="fill_parent"
android:layout_height="wrap_content"
android:id="@+id/listViewHis"
android:layout_below="@+id/tvHisPosts"
/>
</LinearLayout>
</HorizontalScrollView>
</LinearLayout>
解决方案
I have finally achieved it without using any library, have a look at this:
I was receiving json responce as this:
{"searchInfo":{"status":"1","message":"Success","clist":[{"id":"1de57434-795e-49ac-0ca3-5614dacecbd4","name":"Theater","image_url":"http://52.25.198.71/miisecretory/category_images/movie.png"},{"id":"62fe1c92-2192-2ebb-7e92-5614dacad69b","name":"CNG","image_url":"http://52.25.198.71/miisecretory/category_images/cng.png"},{"id":"8060094c-df4f-5290-7983-5614dad31677","name":"Wine-shop","image_url":"http://52.25.198.71/miisecretory/category_images/beer.png"},{"id":"888a90c4-a6b0-c2e2-6b3c-561788e973f6","name":"Chemist","image_url":"http://52.25.198.71/miisecretory/category_images/chemist.png"},{"id":"a39b4ec1-943f-b800-a671-561789a57871","name":"Food","image_url":"http://52.25.198.71/miisecretory/category_images/food.png"},{"id":"c644cc53-2fce-8cbe-0715-5614da9c765f","name":"College","image_url":"http://52.25.198.71/miisecretory/category_images/college.png"},{"id":"c71e8757-072b-1bf4-5b25-5614d980ef15","name":"Hospital","image_url":"http://52.25.198.71/miisecretory/category_images/hospital.png"},{"id":"db835491-d1d2-5467-a1a1-5614d9963c94","name":"Petrol-Pumps","image_url":"http://52.25.198.71/miisecretory/category_images/petrol.png"},{"id":"f13100ca-4052-c0f4-863a-5614d9631afb","name":"ATM","image_url":"http://52.25.198.71/miisecretory/category_images/atm.png"}]}}
so I wanted to create a horizontal scrollview with working click events as I was also have to draw routes on google map so, first I draw a layout for that as like this :
<?xml version="1.0" encoding="utf-8"?>
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:layout_width="match_parent"
android:layout_height="match_parent"
android:orientation="vertical"
android:weightSum="5">
<fragment
android:id="@+id/map"
android:name="com.google.android.gms.maps.SupportMapFragment"
android:layout_width="match_parent"
android:layout_height="0dp"
android:layout_weight="4" />
<HorizontalScrollView
android:id="@+id/horizontalScroll"
android:layout_width="match_parent"
android:layout_height="0dp"
android:layout_weight="1">
<LinearLayout
android:id="@+id/ll"
android:layout_width="match_parent"
android:layout_height="match_parent"
android:gravity="center"
android:orientation="horizontal">
</LinearLayout>
</HorizontalScrollView>
</LinearLayout>
now according to json response which consists of json array I done this:
for (int v = 0; v < collectionInfo.size(); v++) {
/*---------------Creating frame layout----------------------*/
FrameLayout frameLayout = new FrameLayout(ActivityMap.this);
LinearLayout.LayoutParams layoutParams = new LinearLayout.LayoutParams(FrameLayout.LayoutParams.WRAP_CONTENT, getPixelsToDP(90));
layoutParams.rightMargin = getPixelsToDP(10);
frameLayout.setLayoutParams(layoutParams);
/*--------------end of frame layout----------------------------*/
/*---------------Creating image view----------------------*/
final ImageView imgView = new ImageView(ActivityMap.this); //create imageview dynamically
LinearLayout.LayoutParams lpImage = new LinearLayout.LayoutParams(LinearLayout.LayoutParams.WRAP_CONTENT, LinearLayout.LayoutParams.WRAP_CONTENT);
imgView.setImageBitmap(collectionInfo.get(v).getCatImage());
imgView.setLayoutParams(lpImage);
// setting ID to retrieve at later time (same as its position)
imgView.setId(v);
imgView.setOnClickListener(new View.OnClickListener() {
@Override
public void onClick(View v) {
// long id = imgView.getId();
// getting id which is same as its position
Log.i(TAG, "Clicked on " + collectionInfo.get(v.getId()).getCatName());
// getting selected category's data list
new GetSelectedCategoryData().execute(collectionInfo.get(v.getId()).getCatID());
}
});
/*--------------end of image view----------------------------*/
/*---------------Creating Text view----------------------*/
TextView textView = new TextView(ActivityMap.this);//create textview dynamically
textView.setText(collectionInfo.get(v).getCatName());
FrameLayout.LayoutParams lpText = new FrameLayout.LayoutParams(FrameLayout.LayoutParams.WRAP_CONTENT, FrameLayout.LayoutParams.WRAP_CONTENT, Gravity.BOTTOM | Gravity.CENTER);
// Note: LinearLayout.LayoutParams 's gravity was not working so I putted Framelayout as 3 paramater is gravity itself
//lpText.gravity = Gravity.BOTTOM | Gravity.CENTER;
textView.setTextColor(Color.parseColor("#43A047"));
textView.setLayoutParams(lpText);
/*--------------end of Text view----------------------------*/
//Adding views at appropriate places
frameLayout.addView(imgView);
frameLayout.addView(textView);
linearLayout.addView(frameLayout);
}
the trick that is working here is the id that I have assigned to ImageView "imgView.setId(v)" and after that applying onClickListener to that I am again fetching the id of the view....
in this way I have successfully achieved the solution...I have developed this code few days back, I think I should share with everyone....Happy coding...
