从服务器返回的字符串，先转成byte[],然后保存到文件，listview根据uri获取显示

private String textPath;
private List<Map<String, Object>> getList() {
for (int i = 0; i < data.length; i++) {
Map<String, Object> map = new HashMap<String, Object>();

map.put("Rp_ContactName", data[i].getRp_ContactName());
map.put("Rp_ProductName", data[i].getRp_ProductName());

String Rp_AddTime = data[i].getRp_AddTime();
String s = Rp_AddTime.substring(Rp_AddTime.indexOf("(") + 1, Rp_AddTime.indexOf(")"));
map.put("Rp_AddTime", Rp_AddTime);


map.put("Rp_StateID", data[i].getRp_StateID());


boolean sdCardExist = Environment.getExternalStorageState().equals(android.os.Environment.MEDIA_MOUNTED); // 判断sd卡是否存在
if (sdCardExist) {
String packageName = getActivity().getPackageName();
File root = new File(
Environment.getExternalStorageDirectory() + "/Android/data/" + packageName + "/files");
if (!root.exists()) {
root.mkdirs();
}
int currentapiVersion = android.os.Build.VERSION.SDK_INT;
textPath = root.getAbsolutePath() + "/" + s;
File file = new File(textPath);
//从服务端返回的字符串
String str = data[i].getRp_Picture();
//转成byte[]
byte[] bitmapByte = Base64.decode(str, Base64.DEFAULT);
//保存文件
boolean success = FilesUtils.saveFile(textPath, bitmapByte);
if (success == true) {

map.put("textPath", textPath);
}
}
list.add(map);
}
return list;
}

/**

* @param data

*/

public static boolean saveFile(String path, byte[] data) {
boolean success = false;
try {
File file = new File(path);
if (file.exists()) {
file.delete();
}
FileOutputStream fileOutputStream = new FileOutputStream(file);
try {

return true;
} catch (Exception e) {
e.printStackTrace();
} finally {

} catch (Exception e) {

return success;
}

在Adapte中调用（导入glide-3.7.0-sources.jar  和glide-3.7.0.jar）

String s = data.get(position).get("textPath").toString();
String uri = Uri.parse(s).toString();
Glide.with(context).load(uri).error(R.drawable.imagsix).into(holder.tv_image);
