一、简介
自己对OKHttp的封装的对多文件上传、下载（带进度值）操作的小的框架，可实现如下功能：<ol>
<li>多文件上传（带进度值）、表单提交到服务器；</li>
<li>同时提交文件、表单数据到服务器</li>
<li>下载文件保存到到本地（带进度值）;</li>
<li>可以在文件上传/下载时，在开始、结束、进度回调3个方法中自定义内容。</li>
</ol>
二、使用步骤
1、Gradle添加如下2个依赖
allprojects {
repositories {
...
maven { url 'https://jitpack.io' }
}
}
dependencies {
compile 'com.github.zhouxu88:OkHttp3_MultiFile:v1.0'
}
2、多文件上传的调用
//多文件上传（带进度）
private void upload() {
//这个是非ui线程回调，不可直接操作UI
final ProgressListener progressListener = new ProgressListener() {
@Override
public void onProgress(long bytesWrite, long contentLength, boolean done) {
Log.i("TAG", "bytesWrite:" + bytesWrite);
Log.i("TAG", "contentLength" + contentLength);
Log.i("TAG", (100 * bytesWrite) / contentLength + " % done ");
Log.i("TAG", "done:" + done);
Log.i("TAG", "================================");
}
};
//这个是ui线程回调，可直接操作UI
UIProgressListener uiProgressRequestListener = new UIProgressListener() {
@Override
public void onUIProgress(long bytesWrite, long contentLength, boolean done) {
Log.i("TAG", "bytesWrite:" + bytesWrite);
Log.i("TAG", "contentLength" + contentLength);
Log.i("TAG", (100 * bytesWrite) / contentLength + " % done ");
Log.i("TAG", "done:" + done);
Log.i("TAG", "================================");
//ui层回调,设置当前上传的进度值
int progress = (int) ((100 * bytesWrite) / contentLength);
uploadProgress.setProgress(progress);
uploadTV.setText("上传进度值：" + progress + "%");
}
//上传开始
@Override
public void onUIStart(long bytesWrite, long contentLength, boolean done) {
super.onUIStart(bytesWrite, contentLength, done);
Toast.makeText(getApplicationContext(),"开始上传",Toast.LENGTH_SHORT).show();
}
//上传结束
@Override
public void onUIFinish(long bytesWrite, long contentLength, boolean done) {
super.onUIFinish(bytesWrite, contentLength, done);
//uploadProgress.setVisibility(View.GONE); //设置进度条不可见
Toast.makeText(getApplicationContext(),"上传成功",Toast.LENGTH_SHORT).show();
}
};
//开始Post请求,上传文件
OKHttpUtils.doPostRequest(POST_FILE_URL, initUploadFile(), uiProgressRequestListener, new Callback() {
@Override
public void onFailure(Call call, final IOException e) {
Log.i("TAG", "error------> "+e.getMessage());
runOnUiThread(new Runnable() {
@Override
public void run() {
Toast.makeText(MainActivity.this, "上传失败"+e.getMessage(), Toast.LENGTH_SHORT).show();
}
});
}
@Override
public void onResponse(Call call, Response response) throws IOException {
Log.i("TAG", "success---->"+response.body().string());
}
});
}
//初始化上传文件的数据
private List<String> initUploadFile(){
List<String> fileNames = new ArrayList<>();
fileNames.add(Environment.getExternalStoragePublicDirectory(Environment.DIRECTORY_DOWNLOADS)
+ File.separator + "test.txt"); //txt文件
fileNames.add(Environment.getExternalStoragePublicDirectory(Environment.DIRECTORY_DOWNLOADS)
+ File.separator + "bell.png"); //图片
fileNames.add(Environment.getExternalStoragePublicDirectory(Environment.DIRECTORY_MOVIES)
+ File.separator + "kobe.mp4"); //视频
fileNames.add(Environment.getExternalStoragePublicDirectory(Environment.DIRECTORY_MUSIC)
+ File.separator + "xinnian.mp3"); //音乐
return fileNames;
}
3、文件下载的调用
//文件下载
private void download() {
//这个是非ui线程回调，不可直接操作UI
final ProgressListener progressResponseListener = new ProgressListener() {
@Override
public void onProgress(long bytesRead, long contentLength, boolean done) {
Log.i("TAG", "bytesRead:" + bytesRead);
Log.i("TAG", "contentLength:" + contentLength);
Log.i("TAG", "done:" + done);
if (contentLength != -1) {
//长度未知的情况下回返回-1
Log.i("TAG", (100 * bytesRead) / contentLength + "% done");
}
Log.i("TAG", "================================");
}
};
//这个是ui线程回调，可直接操作UI
final UIProgressListener uiProgressResponseListener = new UIProgressListener() {
@Override
public void onUIProgress(long bytesRead, long contentLength, boolean done) {
Log.i("TAG", "bytesRead:" + bytesRead);
Log.i("TAG", "contentLength:" + contentLength);
Log.i("TAG", "done:" + done);
if (contentLength != -1) {
//长度未知的情况下回返回-1
Log.i("TAG", (100 * bytesRead) / contentLength + "% done");
}
Log.i("TAG", "================================");
//ui层回调,设置下载进度
int progress = (int) ((100 * bytesRead) / contentLength);
downloadProgress.setProgress(progress);
downloadTv.setText("下载进度：" + progress +"%");
}
@Override
public void onUIStart(long bytesRead, long contentLength, boolean done) {
super.onUIStart(bytesRead, contentLength, done);
Toast.makeText(getApplicationContext(),"开始下载",Toast.LENGTH_SHORT).show();
}
@Override
public void onUIFinish(long bytesRead, long contentLength, boolean done) {
super.onUIFinish(bytesRead, contentLength, done);
Toast.makeText(getApplicationContext(),"下载完成",Toast.LENGTH_SHORT).show();
}
};
//开启文件下载
OKHttpUtils.downloadAndSaveFile(this,DOWNLOAD_TEST_URL,STORE_DOWNLOAD_FILE_PATH,uiProgressResponseListener);
}
备注
文件上传、下载中的UIProgressListener 实现的3个方法onUIProgress()、onUIStart()、onUIFinish()的内容都可以根据项目需求自定义
