使用volley读取压缩文件的内容（zip、gz）

volley无法直接读取gzip文件，最后通过重写了Request实现了对gzip文件读取

package com.partjob.commonjar.okhttp;import com.android.volley.NetworkResponse;import com.android.volley.ParseError;import com.android.volley.Request;import com.android.volley.Response;import com.android.volley.toolbox.HttpHeaderParser;import com.android.volley.Response.Listener;import java.io.BufferedReader;import java.io.ByteArrayInputStream;import java.io.IOException;import java.io.InputStreamReader;import java.util.zip.GZIPInputStream;/** * 读取压缩文件 */public class GZipRequest extends Request<String> {    private final Listener<String> mListener;    public GZipRequest(int method, String url, Response.Listener<String> listener,                       Response.ErrorListener errorListener) {        super(method, url, errorListener);        mListener = listener;    }    /**     * Creates a new GET request.     *     * @param url           URL to fetch the string at     * @param listener      Listener to receive the String response     * @param errorListener Error listener, or null to ignore errors     */    public GZipRequest(String url, Response.Listener<String> listener, Response.ErrorListener errorListener) {        this(Method.GET, url, listener, errorListener);    }    @Override    protected void deliverResponse(String response) {        mListener.onResponse(response);    }    @Override    protected Response<String> parseNetworkResponse(NetworkResponse paramNetworkResponse) {        String str1 = "";        try {            GZIPInputStream gzipInputStream = new GZIPInputStream(                    new ByteArrayInputStream(paramNetworkResponse.data));            InputStreamReader inputStreamReader = new InputStreamReader(                    gzipInputStream);            BufferedReader bufferedReader = new BufferedReader(                    inputStreamReader);            while (true) {                String str2 = bufferedReader.readLine();                if (str2 == null)                    break;                str1 = str1 + str2;            }            inputStreamReader.close();            bufferedReader.close();            gzipInputStream.close();            return Response.success(str1, HttpHeaderParser.parseCacheHeaders(paramNetworkResponse));        } catch (IOException e) {            return Response.error(new ParseError(e));        }    }}

重写parseNetworkResponse方法就可以实现对gzip文件的读取
