layout中很普通,就是两个button和一个ImageView

在主页面中给按钮添加事件:

packagesuccess.xiaoyu.okhttp3;
importandroid.graphics.Bitmap;
importandroid.graphics.BitmapFactory;
importandroid.os.Environment;
importandroid.os.Handler;
importandroid.os.Message;
importandroid.support.v7.app.AppCompatActivity;
importandroid.os.Bundle;
importandroid.util.Log;
importandroid.view.View;
importandroid.widget.Button;
importandroid.widget.ImageView;
importjava.io.File;
importjava.io.IOException;
importjava.io.InputStream;
importjava.util.concurrent.TimeUnit;
importokhttp3.Call;
importokhttp3.Callback;
importokhttp3.MediaType;
importokhttp3.MultipartBody;
importokhttp3.OkHttpClient;
importokhttp3.Request;
importokhttp3.RequestBody;
importokhttp3.Response;
publicclassMainActivityextendsAppCompatActivity{
privateButtonbutton1,button2;
privateImageViewimageView;
privateHandlerhandler=newHandler(){
publicvoidhandleMessage(Messagemsg){
Bitmapbitmap=(Bitmap)msg.obj;
imageView.setImageBitmap(bitmap);
//Toast.makeText(MainActivity.this,Environment.getExternalStorageDirectory()+"",Toast.LENGTH_LONG).show();
}
};
protectedvoidonCreate(BundlesavedInstanceState){
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(newView.OnClickListener(){//将服务器的图片读取到本地
publicvoidonClick(Viewview){
OkHttpClientokHttpClient=newOkHttpClient();
Requestrequest=newRequest.Builder()
.url("http://115.159.217.226/xy.png")
.build();
okHttpClient.newCall(request).enqueue(newCallback(){
publicvoidonFailure(Callcall,IOExceptione){
}
publicvoidonResponse(Callcall,Responseresponse)throwsIOException{
InputStreaminputStream=response.body().byteStream();
Bitmapbitmap=BitmapFactory.decodeStream(inputStream);
Messagemsg=newMessage();
msg.obj=bitmap;
handler.sendMessage(msg);
}
});
}
});
button2.setOnClickListener(newView.OnClickListener(){
@Override
publicvoidonClick(Viewview){
uploadMultiFile();
}
});
}
privatevoiduploadMultiFile(){//将图片发送到服务器
finalStringurl="http://115.159.217.226/upload.php";
Filefile=newFile(Environment.getExternalStorageDirectory()+"/storage/emulated/0/","xy.jpg");
RequestBodyfileBody=RequestBody.create(MediaType.parse("application/octet-stream"),file);
Filefile2=newFile(Environment.getExternalStorageDirectory()+"/storage/emulated/0/","yyw.jpg");
RequestBodyfileBody2=RequestBody.create(MediaType.parse("application/octet-stream"),file2);
RequestBodyrequestBody=newMultipartBody.Builder()
.setType(MultipartBody.FORM)
.addFormDataPart("image1","xy.jpg",fileBody)
.addFormDataPart("image2","yyw.jpg",fileBody2)
.build();
Requestrequest=newRequest.Builder()
.url(url)
.post(requestBody)
.build();
finalokhttp3.OkHttpClient.BuilderhttpBuilder=newOkHttpClient.Builder();
OkHttpClientokHttpClient=httpBuilder
//设置超时
.connectTimeout(10,TimeUnit.SECONDS)
.writeTimeout(15,TimeUnit.SECONDS)
.build();
okHttpClient.newCall(request).enqueue(newCallback(){
@Override
publicvoidonFailure(Callcall,IOExceptione){
Log.e("aa","uploadMultiFile()e="+e);
}
@Override
publicvoidonResponse(Callcall,Responseresponse)throwsIOException{
Log.i("bb","uploadMultiFile()response="+response.body().string());
}
});
}
}

服务器端代码:

$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;
echojson_encode($arr);
?>
