gradle – How to import RecyclerView for Android L-preview

Posted by: admin March 11, 2020 Leave a comment

Questions:

Trying to use the new RecyclerView from the support library. I downloaded the 20 update for the support library using the SDK manager.

I’ve added the jar file to the libs folder – and added to build path – no luck using the RecyclerView.

Tried to use also the gradle dependency according to Android Developer’s API – not sure if this is the right place to look – this page is related more to AndroidTV :

 com.android.support:recyclerview-v7:20.0.+

Cannot gradle sync the project.

Any ideas?

How to&Answers:

I have created using following lines and this works for me.

implementation 'com.android.support:appcompat-v7:28.0.0'
implementation 'com.android.support:recyclerview-v7:28.0.0'

For AndroidX

implementation 'androidx.recyclerview:recyclerview:1.1.0'
implementation 'androidx.cardview:cardview:1.0.0'

For complete tutorial please see here

Answer:

Figured it out.

You’ll have to add the following gradle dependency :

compile 'com.android.support:recyclerview-v7:+'

another issue I had compiling was the compileSdkVersion. Apparently you’ll have to compile it against android-L

Your build.gradle file should look something like this:

apply plugin: 'android'
android {
    compileSdkVersion 'android-L'
    buildToolsVersion '19.1.0'
    [...]
}
dependencies {
    compile fileTree(dir: 'libs', include: ['*.jar'])
    compile 'com.android.support:recyclerview-v7:+'
}

Answer:

This works for me:

compile 'com.android.support:recyclerview-v7:21.0.0-rc1'

Answer:

RecyclerView can now be added by compiling design dependency in app gradle:

dependencies {
...
compile 'com.android.support:design:24.0.0'
}

Answer:

If You have Compiled SDK Version 22.2.0 then add below dependency for recycler view and cardview additional for support of cardView

// for including all the libarary in the directory lib
compile fileTree(include: ['*.jar'], dir: 'libs')
// for support appcompat
compile 'com.android.support:appcompat-v7:22.2.0'
//for including google support design (it makes possible of implementing material design theme from 2.3 and higher)
`compile ‘com.android.support:design:22.2.0’

for adding the recycler view use following dependency


compile 'com.android.support:recyclerview-v7:22.2.0'

After that click on Build->rebuild project and you are done.

Answer:

compile 'com.android.support:recyclerview-v7:24.2.1'

This works for me.
Try it.

Answer:

The steps before me are just missing one step.

After altering the build.gradle (Module:app) and adding the following dependencies:

compile ‘com.android.support:cardview-v7:21.0.+’
compile ‘com.android.support:recyclerview-v7:21.0.+’

(Add cardview if necessary)

You must then must go to Build > Clean Project to get rid of any errors

Answer:

dependencies {
compile fileTree(dir: 'libs', include: ['*.jar'])
compile 'com.android.support:appcompat-v7:21.0.3'
compile 'com.android.support:recyclerview-v7:21.0.0'
}

Just make your dependencies like above in build.gradle file, worked for me.

Answer:

in my case I fixed it by putting compile 'com.android.support:recyclerview-v7:22.0.0' as a dependency into my gradle build

(with Android studio v. 1.2.1.1 and all sdk’s updated.)

It’s really annoying when codes are updated so fast and the IDE can’t keep track of them, and you have to manually fix for them, wasting time and resources.

But well, at last it works.

Answer:

include the dependency in the build.gradle, and sync the project with gradle files

dependencies {
    implementation fileTree(dir: 'libs', include: ['*.jar'])
    implementation 'com.android.support:appcompat-v7:25.1.0'

    //include the revision no, i.e 25.1.1
    implementation 'com.android.support:recyclerview-v7:25.1.1'
}

Include the revision(here its 25.1.1) to avoid unpredictable builds, check library revisions

Answer:

implementation 'com.android.support:appcompat-v7:28.0.0'
implementation 'com.android.support:recyclerview-v7:28.0.0'

Above works for me in build.gradle file

Answer:

I used a small hack to use the RecyclerView on older devices. I just went into my local m2 repository and picked up the RecyclerView source files and put them into my project.

You can find the sourcecode here:

<Android-SDK>\extras\android\m2repository\com\android\support\recyclerview-v7\21.0.0-rc1\recyclerview-v7-21.0.0-rc1-sources.jar

Answer:

Other answers did not work for me. I had to add this line:

compile ‘com.android.support:recyclerview-v7:21.0.0’

Answer:

-Go to the DESIGN part in activity_main.xml
-In the drag drop pallet select appCompactivity
-In appCompactivity Select RecyclerView
-On Selection a dialog shall appear click OK
-Your project app:gradle will automatically get updated

Answer:

My dependencies;

dependencies {
    compile fileTree(include: ['*.jar'], dir: 'libs')
    compile 'com.android.support:appcompat-v7:25.1.0'

    //RecyclerView dependency
    compile 'com.android.support:recyclerview-v7:25.1.0'

    // Instrumentation dependencies use androidTestCompile
    // (as opposed to testCompile for local unit tests run in the JVM)
    androidTestCompile 'junit:junit:4.12'
    androidTestCompile 'com.android.support:support-annotations:25.1.0'
    androidTestCompile 'com.android.support.test:runner:0.5'
    androidTestCompile 'com.android.support.test:rules:0.5'
}

I added only compile ‘com.android.support:recyclerview-v7:25.1.0’. The important thing is to add RecycleView dependency which is as the same version as appcompat

Answer:

If you using the updated or 2018 Version for Android Studio…

compile 'com.android.support:recyclerview-v7:+'

will give you an error with following message
“Configuration ‘compile’ is obsolete and has been replaced with ‘implementation’ and ‘api’.
It will be removed at the end of 2018.”

Try using this

implementation 'com.android.support:recyclerview-v7:+'

Answer:

I used this one is working for me. One thing needs to be consider that what appcompat version you are using. I am using appcompat-v7:26.+ so this is working for me.

implementation 'com.android.support:recyclerview-v7:26.+'

Answer:

A great way to import the RecyclerView into your project is the RecyclerViewLib. This is an open source library which pulled out the RecyclerView to make it safe and easy implement. You can read the author’s blog post here.

Add the following line as a gradle dependency in your code:

dependencies {
    compile 'com.twotoasters.RecyclerViewLib:library:[email protected]'
}

More info for how to bring in gradle dependencies:

Bosnia you’re right about that being annoying. Gradle may seem complicated but it is extremely powerful and flexible. Everything is done in the language groovy and learning the gradle system is learning another language just so you can build your Android app. It hurts now, but in the long run you’ll love it.

Check out the build.gradle for the same app. https://github.com/twotoasters/RecyclerViewLib/blob/master/sample/build.gradle Where it does the following is where it brings the lib into the module (aka the sample app)

compile (project (':library')) {
    exclude group: 'com.android.support', module: 'support-v4' 
}

Pay attention to the location of this file. This is not the top level build.gradle

Because the lib source is in the same project it is able to do this with the simple ':library'. The exclude tells the lib to use the sample app’s support v4. That isn’t necessary but is a good idea. You don’t have or want to have the lib’s source in your project, so you have to point to the internet for it. In your module’s/app’s build.gradle you would put that line from the beginning of this answer in the same location. Or, if following the samples example, you could replace ':library' with ' com.twotoasters.RecyclerViewLib:library:[email protected] ' and use the excludes.

Answer:

import android.support.v7.widget.RecyclerView;

In Android Studio, importing is not as intuitive as one would hope. Try importing this bit and see how it helps!

Answer:

If anyone still has this issue – you don’t have to change compileSdkVersion, this just defeats the whole purpose of support libraries.

Instead, use these in your gradle.build file:

compile 'com.android.support:cardview-v7:+'
compile 'com.android.support:recyclerview-v7:+'
compile 'com.android.support:palette-v7:+'`

Answer:

This works for me

Define internet permission

 <uses-permission android:name="android.permission.INTERNET" >

Add dependency

compile 'com.squareup.retrofit2:retrofit:2.1.0'
    compile 'com.google.code.gson:gson:2.6.2'
    compile 'com.squareup.retrofit2:converter-gson:2.1.0'
    compile 'com.google.code.gson:gson:2.6.2'
    compile 'com.squareup.retrofit2:converter-gson:2.1.0'
    compile 'com.squareup.okhttp3:logging-interceptor:3.4.1'
    compile 'com.squareup.okhttp3:okhttp:3.4.1'
    compile 'com.squareup.retrofit2:retrofit:2.1.0'
    compile ('com.squareup.retrofit2:converter-simplexml:2.1.0'){
        exclude group: 'stax', module: 'stax-api'
        exclude group: 'stax', module: 'stax'
        exclude group: 'xpp3', module: 'xpp3'
    }

In Main Activity

import android.support.v7.app.AppCompatActivity;
import android.os.Bundle;
import android.util.Log;
import android.widget.TextView;
import android.widget.Toast;

import java.util.List;

import retrofit2.Call;
import retrofit2.Callback;
import retrofit2.Response;
import retrofit2.Retrofit;
import retrofit2.converter.simplexml.SimpleXmlConverterFactory;

public class MainActivity extends AppCompatActivity {
    private BreakfastMenu breakfastMenu;
    List<BreakfastMenu> list;
    TextView responseText;
    APIInterface apiInterface;
    String name;
    String price;
    @Override
    protected void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.activity_main);
        responseText=(TextView)findViewById(R.id.reponseText);
        apiInterface = APIClient.getClient().create(APIInterface.class);


        /**
         GET List Resources
         **/
        Call<BreakfastMenu> call = apiInterface.getBreakfastMenu();
        call.enqueue(new Callback<BreakfastMenu>() {
            @Override
            public void onResponse(Call<BreakfastMenu> call, Response<BreakfastMenu> response) {
               Log.d("TAG", response.code() + "");

                String displayResponse = "";
                BreakfastMenu resource = response.body();
                System.out.println(displayResponse+"display response   ");

                for (Food food : resource.getFoodList())
                {
                    name=food.getName();
                    price=food.getPrice();
                    System.out.println(name+price+"=========================================");
                    displayResponse += food.getName() + " " + food.getPrice()+"\n"+"\n";
                    Toast.makeText(MainActivity.this,name+price,Toast.LENGTH_LONG).show();
                }
                responseText.setText(displayResponse);

            }

            @Override
            public void onFailure(Call<BreakfastMenu> call, Throwable t) {
                call.cancel();
            }
        });

    }
}

Make APIClient.java class

import okhttp3.OkHttpClient;
import okhttp3.logging.HttpLoggingInterceptor;
import retrofit2.Retrofit;
import retrofit2.converter.gson.GsonConverterFactory;
import retrofit2.converter.simplexml.SimpleXmlConverterFactory;

class APIClient {

    private static Retrofit retrofit = null;

    static Retrofit getClient() {

        HttpLoggingInterceptor interceptor = new HttpLoggingInterceptor();
        interceptor.setLevel(HttpLoggingInterceptor.Level.BODY);
        OkHttpClient client = new OkHttpClient.Builder().addInterceptor(interceptor).build();


        retrofit = new Retrofit.Builder()
                .baseUrl("https://www.w3schools.com/")
                .addConverterFactory(SimpleXmlConverterFactory.create())
                .build();



        return retrofit;
    }

}

    @Headers({"Accept: application/xml",
            "User-Agent: Retrofit-Sample-App"})
    Call<BreakfastMenu> getBreakfastMenu();
}

In BreakfastMenu.java

    public BreakfastMenu()
    {
    }

    public List<Food> getFoodList()
    {
        return foodList;
    }

    public void setFoodList(List<Food> foodList)
    {
        this.foodList = foodList;
    }
}

Make Food.java

import org.simpleframework.xml.Element;

Answer:

Just an update:

‘compile’ is obsolete now; it has been replaced with ‘implementation’ and ‘api’.
It will be removed at the end of 2018 I believe. For more information see: http://d.android.com/r/tools/update-dependency-configurations.html

Also all com.android.support libraries must use the exact same version specification; in addition, support libraries such as appcompat-v7 and recyclerview-v7 should not use a different version than the compileSdkVersion.
