I am was making a DEL button which would delete 1 char at a time. I recently added cursor movement to delete in between bud don't know how
I used substrings for deleting normally. It would crash if the number of chars was 0 or 1 before pressing it. I added if statement to fix it.
Here is my delete method
public void delete(View view){
if(textArea.length()==0){
return;
}else if(textArea.length()==1){
if(textArea.getSelectionStart()==textArea.length()){
textArea.setText("");
}else{
return;
}
}else {
int selection = textArea.getSelectionStart();
textArea.setText(textArea.getText().delete(Math.max(0, selection - 1), selection));
}
}
Please Tell How I could Do This To Delete the Char immediately left to the cursor.
I edited the code for the answerer
You can use delete
method of Editable
class like this
public void delete(View view){
int selection = textArea.getSelectionStart();
textArea.setText(textArea.getText().delete(Math.max(0, selection - 1), selection));
}
