我在Android应用中使用Google图片搜索API搜索图片。它工作正常，但我只得到8个查询结果。
如何获得8张以上的图像？（或者有没有更好的方法来搜索图像？）
下面是我的代码：
public class getImagesTask extends AsyncTask<Void, Void, Void>
{
JSONObject json;
ProgressDialog dialog;
@Override
protected void onPreExecute() {
// TODO Auto-generated method stub
super.onPreExecute();
dialog = ProgressDialog.show(GoogleSearchAPIExampleActivity.this, "", "Please wait...");
}
@Override
protected Void doInBackground(Void... params) {
// TODO Auto-generated method stub
URL url;
try {
url = new URL("https://ajax.googleapis.com/ajax/services/search/images?" +
"v=1.0&q="+strSearch+"&rsz=8" ); //&key=ABQIAAAADxhJjHRvoeM2WF3nxP5rCBRcGWwHZ9XQzXD3SWg04vbBlJ3EWxR0b0NVPhZ4xmhQVm3uUBvvRF-VAA&userip=192.168.0.172");
URLConnection connection = url.openConnection();
connection.addRequestProperty("Referer", "http://technotalkative.com");
String line;
StringBuilder builder = new StringBuilder();
BufferedReader reader = new BufferedReader(new InputStreamReader(connection.getInputStream()));
while((line = reader.readLine()) != null) {
builder.append(line);
}
System.out.println("Builder string => "+builder.toString());
json = new JSONObject(builder.toString());
} catch (MalformedURLException e) {
// TODO Auto-generated catch block
e.printStackTrace();
} catch (IOException e) {
// TODO Auto-generated catch block
e.printStackTrace();
} catch (JSONException e) {
// TODO Auto-generated catch block
e.printStackTrace();
}
return null;
}
@Override
protected void onPostExecute(Void result) {
// TODO Auto-generated method stub
super.onPostExecute(result);
if(dialog.isShowing())
{
dialog.dismiss();
}
try {
JSONObject responseObject = json.getJSONObject("responseData");
JSONArray resultArray = responseObject.getJSONArray("results");
listImages = getImageList(resultArray);
SetListViewAdapter(listImages);
System.out.println("Result array length => "+resultArray.length());
} catch (JSONException e) {
// TODO Auto-generated catch block
e.printStackTrace();
}
}
}

在这里，仅使用此API即可获得64个图像结果。
现在在这里发生了什么，如果您设置start variable=9，它将在输出中再添加一个图像，但是第一个图像消失了（因为我们每页只能得到8张图像）。
现在，当您设置start时variable=8，您将获得接下来的8张图像（第2页和接下来的8张图像）。
同样，如果您设置start variable=16，则将获得接下来的8张图像（带有接下来的8张图像的第3页）。
同样，如果您设置start variable=24，则将获得接下来的8张图像（页面编号4和接下来的8张图像），依此类推。
您将获得直到该URL的图像。
url = new URL("https://ajax.googleapis.com/ajax/services/search/images?" +
"v=1.0&q="+strSearch+"&rsz=8&start=56" );
(8th page)
现在从这里开始，如果您递增起始变量（例如）start=57，将不会有输出。
