ChatApp Recycler is Lagging

Question

Hello everyone I am Creating a ChatApp and in which i am getting message of Different type

• Text
• Image
• Audio
• Video I am checking that whether the message is of me or the other user in getItemViewType method of my recyler Adapter and than checking the message type in OnCreateViewholder and passing the particular Binding at runtime so that My App works smoothly but the problem is that The app is lagging when the I click on previous activity item to open my chat activity it takes its sweet time of 1 - 2 seconds and when i am in my Chat Activity the Screen Lags when i scroll the total amount of views which are used in recyler view are 10 5 for sending side and 5 for receiving side

Following is my MessageAdapter Which also contains Viewholder
