我在我的Android应用中使用Google图片搜索API来搜索图片.它工作正常,但我只得到8个查询结果.
以下是我的代码：
public class getimagesTask extends AsyncTaskodo 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();
}
}
}
logcat的：

最佳答案
url = new URL("https://ajax.googleapis.com/ajax/services/search/images?" +
"v=1.0&q="+strSearch+"&rsz=8&start=0" );
在这里,您只能使用此API获得64个图像结果.
现在发生了什么,如果你设置start variable = 9,它将在输出中再添加一个图像,但第一个图像将消失(因为我们每页只能获得8个图像).
现在,当您设置start variable = 8时,您将获得接下来的8个图像(第2页图像的页面编号为2).
同样,如果您设置start variable = 16,您将获得接下来的8个图像(第3页,其中包含下8个图像).
同样,如果您设置start variable = 24,您将获得接下来的8个图像(第4页,其中包含接下来的8个图像),依此类推.
您将获得图像,直到此URL.
url = new URL("https://ajax.googleapis.com/ajax/services/search/images?" +
"v=1.0&q="+strSearch+"&rsz=8&start=56" );
(8th page)
