Step 1 : create Rest Interface like below attached find it(watch only).
Step 2 : create MainActivity like below attached find it.
Step 3: create gradle add it and (Sync) it.
Step 4 : create pojo classes using json example as shown below.
Note: use jsonSchematopojo site to generae model , then name the first class is "Example".
over.
step:1:
Gson gson = new Gson();
Retrofit retrofit = new Retrofit.Builder()
.baseUrl("http://drapp.sciensdemos.in/index.php/")
.addConverterFactory(GsonConverterFactory.create(gson))
.build();
ServiceOperations serviceOperations = retrofit.create(ServiceOperations.class);
Call<Example> call = serviceOperations.all();
Step 2:
public class MainActivity extends AppCompatActivity{
private final String BASEURL = "http://drapp.------demos.in/index.php/";
Gson gson = new Gson();
Retrofit retrofit = new Retrofit.Builder()
.baseUrl("http://drapp.sciensdemos.in/index.php/")
.addConverterFactory(GsonConverterFactory.create(gson))
.build();
ServiceOperations serviceOperations = retrofit.create(ServiceOperations.class);
Call<Example> call = serviceOperations.all();
call.enqueue(new Callback<Example>() {
@Override
public void onResponse(Call<Example> call, Response<Example> response) {
Log.d("Lokesh",""+response.message());
Toast.makeText(MainActivity.this, response.isSuccessful()+"", Toast.LENGTH_SHORT).show();
Example examples =response.body();
if(examples == null){
Toast.makeText(MainActivity.this, "it is null", Toast.LENGTH_SHORT).show();
}else {
Toast.makeText(MainActivity.this, examples.getData().get(0).getSpecializationName(), Toast.LENGTH_SHORT).show();
}
}
@Override
public void onFailure(Call<Example> call, Throwable t) {
}
});
}
Step 3:
compile 'com.squareup.retrofit2:retrofit:2.1.0'
compile 'com.squareup.retrofit2:converter-gson:2.1.0'
Step 4 :
{
"status": "sucess",
"data": [
{
"specialization_id": "1",
"specialization_name": "Physical Medicine and Rehabilitation"
} ],
"statusCode": 200
}
out put :
true,
Physical Medicine and Rehabilitation shown toast.
