解决方案
URL =新的URL（https://ajax.googleapis.com/ajax/services/search/images？ +
V = 1.0＆安培; Q =+ strSearch +与＆amp; RSZ = 8＆安培;开始= 0）;
在这里，你可以得到64图像效果只能使用此API。
现在在这里会发生什么，如果你设置启动变量= 9 ，它会增加一个图像的输出，但第一个图像将消失（因为我们只能得到每页8图像）。
现在，当您设置启动变量= 8 ，你会得到一个8影像（第数字2与接下来的8个图像）。
另外，如果设置启动变量= 16 ，你会得到一个8影像（第number3的与未来的8图像）。
另外，如果设置启动变量= 24 ，你会得到一个8影像（第号码4与接下来的8图像）等。
您将获得的图像到这个网址。
URL =新的URL（https://ajax.googleapis.com/ajax/services/search/images？+
V = 1.0＆安培; Q =+ strSearch +与＆amp; RSZ = 8＆安培;开始= 56）;
（第8页）
现在从这里，如果你开始增加变量，如开始= 57 ，就没有输出。
I'm using Google image search API in my Android app to search images. It is working fine, but I'm getting only 8 results of query.
How can I get more than 8 images? (Or is there any better way to search images?)
Below is my code:
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();
}
}
}

url = new URL("https://ajax.googleapis.com/ajax/services/search/images?" +
"v=1.0&q="+strSearch+"&rsz=8&start=0" );
Here you can get 64 image results only using this API.
Now here what happens, if you set start variable=9, it will add one more image in output, but the first image will gone (as we can get only 8 images per page).
Now when you set start variable=8, you will get next 8 images (page number2 with next 8 images).
Again, if you set start variable=16, you will get next 8 images (page number3 with next 8 images).
Again, if you set start variable=24, you will get next 8 images (page number4 with next 8 images) and so on.
You will get images till this URL.
url = new URL("https://ajax.googleapis.com/ajax/services/search/images?" +
"v=1.0&q="+strSearch+"&rsz=8&start=56" );
(8th page)
Now from here if you increment start variable such as start=57, there will be no output.
