layout中很普通,就是两个button和一个ImageView
android:layout_width="match_parent"
android:layout_height="match_parent"
android:orientation="vertical"
>
android:id="@+id/test"
android:layout_width="368dp"
android:layout_height="wrap_content"
android:text="button1"
android:textAllCaps="false" />
android:id="@+id/test2"
android:layout_width="368dp"
android:layout_height="wrap_content"
android:text="button2"
android:textAllCaps="false"
/>
android:id="@+id/image"
android:layout_width="0dp"
android:layout_height="495dp"
/>
在主页面中给按钮添加事件:

import android.os.Message;

public class MainActivity extends AppCompatActivity {

}
};

super.onCreate(savedInstanceState);
setContentView(R.layout.layout);
button1 = (Button)findViewById(R.id.test);
button2 = (Button)findViewById(R.id.test2);
imageView = (ImageView)findViewById(R.id.image);
button1.setOnClickListener(new View.OnClickListener() {//将服务器的图片读取到本地
public void onClick(View view) {
OkHttpClient okHttpClient = new OkHttpClient();
Request request = new Request.Builder()
.url("https://cache.yisu.com/upload/information/20200623/125/127052.png")
.build();
okHttpClient.newCall(request).enqueue(new Callback() {

public void onResponse(Call call, Response response) throws IOException {
InputStream inputStream = response.body().byteStream();
Bitmap bitmap = BitmapFactory.decodeStream(inputStream);
Message msg = new Message();

handler.sendMessage(msg);
}
});
}
});
button2.setOnClickListener(new View.OnClickListener() {
@Override
public void onClick(View view) {
uploadMultiFile();
}
});
}
private void uploadMultiFile() {//将图片发送到服务器
final String url = "https://cache.yisu.com/upload/information/20200623/125/127064.jpg");
RequestBody fileBody = RequestBody.create(MediaType.parse("application/octet-stream"), file);

RequestBody fileBody2 = RequestBody.create(MediaType.parse("application/octet-stream"), file2);
RequestBody requestBody = new MultipartBody.Builder()
.setType(MultipartBody.FORM)
.addFormDataPart("image1", "xy.jpg", fileBody)
.addFormDataPart("image2", "yyw.jpg", fileBody2)
.build();
Request request = new Request.Builder()
.url(url)
.post(requestBody)
.build();
final okhttp3.OkHttpClient.Builder httpBuilder = new OkHttpClient.Builder();
OkHttpClient okHttpClient = httpBuilder
//设置超时
.connectTimeout(10, TimeUnit.SECONDS)
.writeTimeout(15, TimeUnit.SECONDS)
.build();
okHttpClient.newCall(request).enqueue(new Callback() {
@Override
public void onFailure(Call call, IOException e) {
Log.e("aa", "uploadMultiFile() e=" + e);
}
@Override
public void onResponse(Call call, Response response) throws IOException {
Log.i("bb", "uploadMultiFile() response=" + response.body().string());
}
});
}
}
服务器端代码:
header('Content-type: application/json;charset=utf-8');
if(empty($_FILES)) die('{"status":0,"msg":"错误提交"}');
$dirPath = './img/';//设置文件保存的目录
if(!is_dir($dirPath)){
//目录不存在则创建目录
@mkdir($dirPath);
}
$count = count($_FILES);//所有文件数
if($count<1) die('{"status":0,"msg":"错误提交"}');//没有提交的文件
$success = $failure = 0;
foreach($_FILES as $key => $value){
//循环遍历数据
$tmp = $value['name'];//获取上传文件名
$tmpName = $value['tmp_name'];//临时文件路径
//上传的文件会被保存到php临时目录,调用函数将文件复制到指定目录
if(move_uploaded_file($tmpName,$dirPath.date('YmdHis').'_'.$tmp)){
$success++;
}else{
$failure++;
}
}
$arr['status'] = 1;
$arr['msg'] = '提交成功';
$arr['success'] = $success;
$arr['failure'] = $failure;
echo json_encode($arr);
?>
