How to check if a TextView contains a certain string

Question

Hi I want to add an if statement that checks to see if a text in a textview (called TextView1) contains a ".". I know I can check to see if the text equals ".". But I dont know how to check if the text contains a ".". Can anyone help me with this? Thanks

I dont know what to do to TextArea1 to check if it contains a decimal point

if (TextArea1      ){
    //Do Something
}

Answer 1

if(TextArea1.getText().toString().contains("."))
