ChatView for Android


This is an Android library which can be used to add chat functionality to your android application with just a few lines of code.
This library is still in beta but will be improved over time.

Version

Installation

Add this to your root build.gradle at the end of repositories:

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

Then add dependency

dependencies {
	compile 'com.github.shrikanth7698:ChatView:v0.1.2'
}

Usage

Drop the ChatView in your XML layout as is shown below:

    <com.shrikanthravi.chatview.widget.ChatView
        android:layout_width="match_parent"
        android:layout_height="match_parent"
        app:showSenderLayout="false" 
        app:leftBubbleLayoutColor="#ff7b7b"
        app:rightBubbleLayoutColor="@color/colorAccent2"
        app:leftBubbleTextColor="@android:color/white"
        app:rightBubbleTextColor="@android:color/black"
        android:layout_above="@+id/sendLL"
        app:showSenderName="true"
        android:id="@+id/chatView">

    </com.shrikanthravi.chatview.widget.ChatView>

don't forget to add this attribute to your root layout.

xmlns:app="http://schemas.android.com/apk/res-auto"

And then in your Activity or Fragment

ChatView chatView = (ChatView) findViewById(R.id.chatview);

Sample code

//sample code to add message to right
Message message = new Message();
                    message.setBody(messageET.getText().toString().trim()); //message body
                    message.setType(Message.RightSimpleMessage); //message type
                    message.setTime(getTime()); //message time (String)
                    message.setUserName("Groot"); //sender name
		    //sender icon
                    message.setUserIcon(Uri.parse("android.resource://com.shrikanthravi.chatviewlibrary/drawable/groot")); 
                    chatView.addMessage(message);
		    
//sample code to add message to left
Message message1 = new Message();
                    message1.setBody(messageET.getText().toString().trim());
                    message1.setType(Message.LeftSimpleMessage);
                    message1.setTime(getTime());
                    message1.setUserName("Hodor");
                    message1.setUserIcon(Uri.parse("android.resource://com.shrikanthravi.chatviewlibrary/drawable/hodor"));
		    chatView.addMessage(message);

//to clear messages
chatview.clearMessages();

//to remove message
chatview.remove(position) //or  chatview.remove(message)

		    

Message types

//Message.LeftSimpleMessage
	Message message = new Message();
	message.setType(Message.LeftSimpleMessage);
	message.setBody(body); //string
	message.setTime(getTime());
	chatView.addMessage(message);
	
//Message.RightSimpleMessage
	Message message = new Message();
	message.setType(Message.RightSimpleMessage);
	message.setBody(body); //string
	message.setTime(getTime());
	chatView.addMessage(message);
	
//Message.LeftSingleImage  (when clicked it will go to fullscreen mode)
	Message message = new Message();
	List<Uri> mSelected  = new ArrayList<>();
	mselected.add(Uri.parse("Your image"))
	message.setTime(getTime());
	message.setType(Message.LeftSingleImage);
	message.setImageList(mSelected);
	chatView.addMessage(message);	
	
// Message.RightSingleImage (when clicked it will go to fullscreen mode)
	Message message = new Message();
	List<Uri> mSelected  = new ArrayList<>();
	mselected.add(Uri.parse("Your image"));
	message.setTime(getTime());
	message.setType(Message.RightSingleImage);
	message.setImageList(mSelected);	
	chatView.addMessage(message);
	
// Message.LeftMultipleImages (can hold upto 10 images in a single row as a collage view)
	Message message = new Message();
	List<Uri> mSelected  = new ArrayList<>();
	mselected.add(Uri.parse("Your image"));
	mselected.add(Uri.parse("Your image"));
	mselected.add(Uri.parse("Your image"));	
	message.setTime(getTime());
	message.setType(Message.LeftMultipleImages);
	message.setImageList(mSelected);
	chatView.addMessage(message);
	
// Message.RightMultipleImages (can hold upto 10 images in a single row as a collage view)
	Message message = new Message();
	List<Uri> mSelected  = new ArrayList<>();
	mselected.add(Uri.parse("Your image"));
	mselected.add(Uri.parse("Your image"));
	mselected.add(Uri.parse("Your image"));	
	message.setTime(getTime());
	message.setType(Message.RightMultipleImages);
	message.setImageList(mSelected);
	chatView.addMessage(message);
	
// Message.LeftVideo (when clicked it will go to fullscreen mode)	
	Message message = new Message();
	message.setType(Message.LeftVideo);
        message.setTime(getTime());
	message.setUserName("Hodor");
	message.setVideoUri(Uri.parse(getPath(data.getData())));
	message.setUserIcon(Uri.parse("android.resource://com.shrikanthravi.chatviewlibrary/drawable/hodor"));
	hatView.addMessage(message);

// Message.RightVideo (when clicked it will go to fullscreen mode)
	Message message = new Message();
	message.setType(Message.RightVideo);
	message.setTime(getTime());
	message.setUserName("Groot");
	message.setVideoUri(Uri.parse(getPath(data.getData())));
	message.setUserIcon(Uri.parse("android.resource://com.shrikanthravi.chatviewlibrary/drawable/groot"));
	chatView.addMessage(message);	

Sender Layout

You should have a accent color in your colors.xml otherwise view will crash.

You can hide or show sender layout

app:showSenderLayout="true or false"

This is still in beta

Sender Layout has 4 buttons for now.

  • Send Button

  • Camera Button

  • Gallery Button

  • Video Button

and a Text box

You can change the color of buttons by changing the accent color you use in your app.

Note: You should use your own logic of picking images,videos and capturing images.

In this sample I used an external library to pick images from gallery.

	//Send button click listerer
        chatView.setOnClickSendButtonListener(new ChatView.OnClickSendButtonListener() {
            @Override
            public void onSendButtonClick(String body) {
                if(switchbool) {
                    Message message = new Message();
                    message.setBody(body);
                    message.setType(Message.RightSimpleMessage);
                    message.setTime(getTime());
                    message.setUserName("Groot");
                    message.setUserIcon(Uri.parse("android.resource://com.shrikanthravi.chatviewlibrary/drawable/groot"));
                    chatView.addMessage(message);

                    switchbool=false;
                }
                else{
                    Message message1 = new Message();
                    message1.setBody(body);
                    message1.setType(Message.LeftSimpleMessage);
                    message1.setTime(getTime());
                    message1.setUserName("Hodor");
                    message1.setUserIcon(Uri.parse("android.resource://com.shrikanthravi.chatviewlibrary/drawable/hodor"));
                    chatView.addMessage(message1);

                    switchbool=true;
                }
            }
        });

        //Gallery button click listener
        chatView.setOnClickGalleryButtonListener(new ChatView.OnClickGalleryButtonListener() {
            @Override
            public void onGalleryButtonClick() {
                Matisse.from(ChatViewTestActivity.this)
                        .choose(MimeType.allOf())
                        .countable(true)
                        .maxSelectable(9)
                        .restrictOrientation(ActivityInfo.SCREEN_ORIENTATION_UNSPECIFIED)
                        .thumbnailScale(0.85f)
                        .imageEngine(new PicassoEngine())
                        .forResult(imagePickerRequestCode);
            }
        });

        //Video button click listener
        chatView.setOnClickVideoButtonListener(new ChatView.OnClickVideoButtonListener() {
            @Override
            public void onVideoButtonClick() {
                Intent i = new Intent(Intent.ACTION_PICK, android.provider.MediaStore.Video.Media.EXTERNAL_CONTENT_URI);
                i.setType("video/*");
                startActivityForResult(i, SELECT_VIDEO);
            }
        });

        //Camera button click listener
        chatView.setOnClickCameraButtonListener(new ChatView.OnClickCameraButtonListener() {
            @Override
            public void onCameraButtonClicked() {
                Intent cameraIntent = new Intent(android.provider.MediaStore.ACTION_IMAGE_CAPTURE);
                File file = new File(Environment.getExternalStorageDirectory(), "MyPhoto.jpg");
                file.delete();
                File file1 = new File(Environment.getExternalStorageDirectory(), "MyPhoto.jpg");

                Uri uri = FileProvider.getUriForFile(ChatViewTestActivity.this, getApplicationContext().getPackageName() + ".provider", file1);
                cameraIntent.putExtra(android.provider.MediaStore.EXTRA_OUTPUT, uri);
                startActivityForResult(cameraIntent, CAMERA_REQUEST);
            }
        });
	
	
	@Override
    protected void onActivityResult(int requestCode, int resultCode, Intent data) {
        super.onActivityResult(requestCode, resultCode, data);

        //Image Selection result
        if (requestCode == imagePickerRequestCode && resultCode == RESULT_OK) {
            mSelected = Matisse.obtainResult(data);

Customization

Note: You can customize the chatview in both xml and java way.

//xml
