Android Retrofit Tutorial
Android Retrofit Example
Add Below CompileLine in module level "app.gradle" file
compile 'com.squareup.retrofit2:retrofit:2.0.2'
compile 'com.squareup.retrofit2:converter-gson:2.1.0'
compile 'com.squareup.okhttp3:logging-interceptor:3.0.1'

AdapterClass.Java

Result result=text.get(position);

}
Creat Interface calss for handling Get and Post the data
create interface "APIInterface"
import okhttp3.MultipartBody;
import okhttp3.RequestBody;
import retrofit2.Call;
import retrofit2.http.Field;
import retrofit2.http.FormUrlEncoded;
import retrofit2.http.Multipart;
import retrofit2.http.POST;
import retrofit2.http.Part;
/**
* Created by Semwal on 1/24/2018.
*/
public interface APIService {
@FormUrlEncoded
@POST("/jason/driver_json.php/driverhistory")
Call<PojoClass> pojoClass(@Field("driver_id") String id);
}
Create Xml files
activity_recycle.xml
<?xml version="1.0" encoding="utf-8"?>
<RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:layout_width="match_parent"
android:layout_height="match_parent">
<ScrollView
android:layout_width="match_parent"
android:layout_height="match_parent">
<android.support.v7.widget.RecyclerView
android:id="@+id/recycler_view"
android:layout_width="match_parent"
android:layout_height="match_parent"
android:scrollbars="vertical" />
</ScrollView>
</RelativeLayout>
adapter_recyclerview.xml
<?xml version="1.0" encoding="utf-8"?>
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:orientation="vertical" android:layout_width="match_parent"
android:layout_height="wrap_content">
<TextView
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:id="@+id/textView"/>
</LinearLayout>
Post Image to Database Using Retrofit
First Convert image in File typeThen convert image file path in RequestBody
final RequestBody requestBody1 = RequestBody.create(MediaType.parse("*/*"), ImageFileFormet);
Then Convert requestBody in MultipartBody.Part
MultipartBody.Part Image = MultipartBody.Part.createFormData("databse_key", ImageFileFormet.getName(), requestBody1);
When you have to send text data with image in database then convert text into requestBody
RequestBody text = RequestBody.create(MediaType.parse("text/plain"), ""yourText);
Call webservice like this
new WebService().postData(Image,text);
getImage in WebService class like this/
public void postData(MultipartBody.Part Image,RequestBody text){....
Call<SignUpResponse> call = webInterface.pojoClass(Image,text);
}
In InterFace use below code to send data
@Multipart
@POST("url/")
Call<PojoClass> pojoClass((@Part MultipartBody.Part image,
@Part("text_key") RequestBody text
);
