How to Use

You can import this library to your project by adding following dependency to your build.gradle :

repositories {
    jcenter()
}

dependencies {
    compile 'com.fenlisproject.elf:core:0.2.5'
}

Basic Setup

Extends BaseApplication

First step to use this library is to Make your Application class extend BaseApplication.

public class SampleApplication extends BaseApplication {

    @Override
    public void onCreate() {
        super.onCreate();
    }
}

Don't forget change application name in your manifest

<?xml version="1.0" encoding="utf-8"?>
<manifest ...>
...
    <application
        android:name="your.package.name.SampleApplication">
    </application>
</manifest>

Extends BaseActivity

In you want to utilize Binding feature, you must extends your Activity with BaseActivity. BaseActivity itself extends from AppCompatActivity which use Android Support Fragment (appcompatv7). Define content view by @ContentView annotation. It will call setContentView for you at Runtime. Method onContentViewCreated is called right before onCreate finish. You you can treat this method same as onCreate method. Do what you usually do in onCreate in this method.

@ContentView(R.layout.activity_main)
public class MainActivity extends BaseActivity {

    @ViewId(R.id.textview1)
    private TextView textView1;

    @Override
    protected void onContentViewCreated() {
        // Yo can safely access to textView1 in this method without call findViewById(). That's the magic
        textView1.setText("Hello Elf");
    }
}

Extends BaseFragment

If you use Fragment, then you can extend your fragment with BaseFragment. And the other steps are same as when you use Activity.

@ContentView(R.layout.fragment_home)
public class HomeFragment extends BaseFragment {

    @Override
    protected void onContentViewCreated() {
        // Treat this method as onCreateView() without inflate the layout
    }
    
    @OnClick(R.id.button1)
    public void onButton1Clicked() {
        // You can even bind button click listener without store it as variable.
    }
}
