GraphStream -- Android Viewer Test

This repository contains some usable examples of gs-ui-android viewer.

Install UI

gs-ui-android is a plugin to the gs-core main project.

The release comes with a pre-packaged aar file named gs-ui-android.aar that contains the GraphStream viewer classes. It depends on the root project gs-core.

For using Graphstream, your project must run with java 8

Add the .aar in your project following these instructions : https://developer.android.com/studio/projects/android-library.html#AddDependency

You can download GraphStream on the github releases pages:

• gs-core
• gs-ui-android

Gradle users, you may include gs-core and gs-ui-android as a dependency to your project using https://jitpack.io. Simply add the jitpack repository to the pom.xml:

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

then, add the gs-core and gs-ui-android to your dependencies:

dependencies {
    api 'com.github.graphstream:gs-ui-android:2.0'
    api 'com.github.graphstream:gs-core:2.0'
}

You can use any version of gs-core and gs-ui-android you need, provided they are the same. Simply specify the desired version in the <version> tag. The version can be a git tag name (e.g. 2.0), a commit number, or a branch name followed by -SNAPSHOT (e.g. dev-SNAPSHOT). More details on the possible versions on jitpack.

Configure UI

For the convenience of the users, a default Android Fragment (org.graphstream.ui.android_viewer.util.DefaultFragment) is provided. The Fragment can be used like so:

public void display(Bundle savedInstanceState, Graph graph, boolean autoLayout) {
    if (savedInstanceState == null) {
        FragmentManager fm = getSupportFragmentManager();

        // find fragment or create him
        fragment = (DefaultFragment) fm.findFragmentByTag("fragment_tag");
        if (null == fragment) {
            fragment = new DefaultFragment();
            fragment.init(graph, autoLayout);
        }

        // Add the fragment in the layout and commit
        FragmentTransaction ft = fm.beginTransaction() ;
        ft.add(CONTENT_VIEW_ID, fragment).commit();
    }
}
