Android TextView : “Do not concatenate text displayed with setText”

Question

I am setting text using setText() by following way.

prodNameView.setText(\"\" + name);

prodOriginalPriceView.setText(\"\" + String.format(g         


        

Answer 1

I ran into the same lint error message and solved it this way.

Initially my code was:

private void displayQuantity(int quantity) {
    TextView quantityTextView = (TextView) findViewById(R.id.quantity_text_view);
    quantityTextView.setText("" + quantity);
}

I got the following error

Do not concatenate text displayed with setText. Use resource string with placeholders.

So, I added this to strings.xml

%d

Which is my initial "" + a placeholder for my number(quantity).

Note: My quantity variable was previously defined and is what I wanted to append to the string. My code as a result was

private void displayQuantity(int quantity) {
    TextView quantityTextView = (TextView) findViewById(R.id.quantity_text_view);
    quantityTextView.setText(getString(R.string.blank, quantity));
}

After this, my error went away. The behavior in the app did not change and my quantity continued to display as I wanted it to now without a lint error.
