CustomViewAnnotations

Generate a custom Factory2 class to speed inflate custom views without defaulting to reflection.

How to Get It

project build.gradle

allprojects {
    repositories {
    	...
	maven { url 'https://jitpack.io' }
    }
}

module build.gradle

dependencies {
    implementation 'com.github.kevinwang5658.CustomViewAnnotations:cva-annotations:1.0'
    
    //For java
    annotationProcessor 'com.github.kevinwang5658.CustomViewAnnotations:cva-compiler:1.0'
    
    //For kotlin
    kapt 'com.github.kevinwang5658.CustomViewAnnontations:cva-compiler:1.0'
}

How to Use

CustomView.java

//Annotate custom view classes with @CustomView
@CustomView
public class CustomView extends View

Activity.java

// Set the custom factory before setContentView within your activity.
@Override
protected void onCreate(Bundle savedInstanceState) {
    super.onCreate(savedInstanceState);
    inflater = LayoutInflater.from(this).cloneInContext(this);
    inflater.setFactory2(new CustomInflaterFactory());
    setContentView(R.layout.activity_main);
}

@NonNull
@Override
public LayoutInflater getLayoutInflater() {
    return inflater;
}

// You only need this if you get LayoutInflater using getSystemService(LAYOUT_INFLATER_SERVICE)
@Override
public Object getSystemService(String name) {
    if (name.equals(LAYOUT_INFLATER_SERVICE)) {
        if (inflater== null) {
            inflater = (LayoutInflater) super.getSystemService(name);
        }
        return inflater;
    }
    return super.getSystemService(name);
}

And that's all!
