setTextSize(++size) increases font size a lot not just a little
android, font-size, increment
Solution
getTextSize()
the size (in pixels) of the default text size in this TextView.
use
setTextSize(TypedValue.COMPLEX_UNIT_PX, ++tempSize);
`setTextSize` uses `scaled pixel` by default (`setTextSize(int)`), with `setTextSize(int, int)` you say the unit to use.
Problem
I am trying to implement a button that will increase the font size of text in `TextView` I have came up with the following : ``` Button biggerFont; TextView centerTextView; @Override protected void onCreate(Bundle savedInstanceState) { super.onCreate(savedInstanceState); setContentView(R.layout.activity_main); biggerFont = (Button) findViewById(R.id.btn_bigger_font); centerTextView = (TextView) findViewById(R.id.textView_center); biggerFont.setOnClickListener(new OnClickListener() { @Override public void onClick(View v) { float tempSize = centerTextView.getTextSize(); Log.d(USER_SERVICE, Float.toString(tempSize)); centerTextView.setTextSize(++tempSize); } }); // ... } ``` But this will increase the font size a lot! each time I click the button. On logging I have check and `tempSize` increases not by 1 but irregularly (44->90->182). I have also tried using ``` float tempSize = centerTextView.getTextSize() + 1; ``` but the same thing.
