JagarYousef / Mindo

• Create complicated items and connections easily
• Flexibility (Custom connections, distance, full control of shapes)
• Save the view directly as an image
• Zooming and Scrolling of the view (v2.x.x and above)

Installation:

Step 1. Add it in your root build.gradle at the end of repositories:

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

Step 2. Add the dependency

	dependencies {
	        implementation 'com.github.JagarYousef:Mindo:2.0.0'
	}

Quick Usage Guide:

1. Create a MindMappingView in your xml layout:

<me.jagar.mindmappingandroidlibrary.Views.MindMappingView
    android:id="@+id/mind_mapping_view"
    android:background="#C4B8B8"
    android:layout_width="match_parent"
    android:layout_height="match_parent" />
<!---You need to add background to display connections-->

2. After initialization in the activity you can use it to add the root (Central Item) and other items in parent/item pairs.

• Adding the central item:

Item item = new Item(MainActivity.this, "Root", "This is an root item", true);
mindMappingView.addCentralItem(item, false); //I didn't want to make the root drag able

• An example of adding an item where its parent is the root item:

Item child = new Item(MainActivity.this, "Child", "This is a child", true);
mindMappingView.addItem(child, item, 200, 10, ItemLocation.TOP, true, null); //It will be drag able but there will not be a text on the connection between the root and the child

• Adding ConnectionTextMessage (the text on the connection between the item and its root):

ConnectionTextMessage connectionTextMessage = new ConnectionTextMessage(MainActivity.this);
connectionTextMessage.setText("This message will be displayed on the connection between Child and Root");
mindMappingView.addItem(child, item, 200, 10, ItemLocation.TOP, true, connectionTextMessage); //It will be drag able and there will be a text on the connection between the root and the child

• Adding a CustomConnection in the case where there is no root and child:

mindMappingView.addCustomConnection(child1, ItemLocation.BOTTOM, child2, ItemLocation.RIGHT, connectionTextMessage,  5,"#000000", 10, 15);

• You can save the view easily as an image using this function:

//Do not forget the permissions
SaveAs.saveAsImage(MindMappingView, PATH_WHERE_IMAGE_WILL_BE_SAVED);

• If you set the item as drag able, you need a different way to add OnClikcListener for this item:

mindMappingView.setOnItemClicked(new OnItemClicked() {
    @Override
    public void OnClick(Item item) {
        item.setPressed(true);
        if (item == child){
            Toast.makeText(MainActivity.this, "child is clicked", Toast.LENGTH_LONG)
                    .show();
        }
        else if (item == root){
            Toast.makeText(MainActivity.this, "root is clicked", Toast.LENGTH_LONG)
                    .show();
        }
    }
});

Zooming:

From version 2.0.0 you are able to include the MindMappingView inside a ZoomLayout that comes with too many options of zooming and scrolling, BUT it is highly recommended to keep the MindMappingView in a fixed size when using this feature, like the example below:

<?xml version="1.0" encoding="utf-8"?>
<me.jagar.mindmappingandroidlibrary.Zoom.ZoomLayout xmlns:app="http://schemas.android.com/apk/res-auto"
    xmlns:tools="http://schemas.android.com/tools"
    xmlns:android="http://schemas.android.com/apk/res/android"
    android:layout_width="match_parent"
    tools:context=".MainActivity"
    android:layout_gravity="center"
    android:gravity="center"
    android:layout_height="match_parent"
    android:scrollbars="vertical|horizontal"
    app:transformation="centerInside"
    app:transformationGravity="auto"
    app:alignment="center"
    app:overScrollHorizontal="true"
    app:overScrollVertical="true"
    app:overPinchable="true"
    app:horizontalPanEnabled="true"
    app:verticalPanEnabled="true"
    app:zoomEnabled="true"
    app:flingEnabled="false"
    app:scrollEnabled="true"
    app:oneFingerScrollEnabled="false"
    app:twoFingersScrollEnabled="true"
    app:threeFingersScrollEnabled="true"
    app:minZoom="0.7"
    app:minZoomType="zoom"
    app:maxZoom="2.5"
    app:maxZoomType="zoom"
    app:animationDuration="280"
    app:hasClickableChildren="true">
        <me.jagar.mindmappingandroidlibrary.Views.MindMappingView
            android:layout_width="1000dp"
            android:background="#C4B8B8"
            android:id="@+id/mind_mapping_view"
            android:layout_height="1000dp" />
</me.jagar.mindmappingandroidlibrary.Zoom.ZoomLayout>

You can control the zoom layout programmatically like below:

zoomLayout.panTo(x, y, true); // Shorthand for zoomLayout.getEngine().panTo(x, y, true)
zoomLayout.panBy(deltaX, deltaY, true);
zoomLayout.zoomTo(zoom, true);
zoomLayout.zoomBy(factor, true);
zoomLayout.realZoomTo(realZoom, true);
zoomLayout.moveTo(zoom, x, y, true);

Customization:

The view, its items and the connection texts are extended from other views so all its features can be applied except OnClickListener in dragged items:
