title: How to use AutoFitTextView
body: <p>Somedays ago, I found this code to resize text inside TextView. But, how can I use it and call it into my project. Im a newbie :)</p>
  
  <pre><code>public class AutoFitTextView extends TextView {
  
  public AutoFitTextView(Context context) {
      super(context);
      init();
  }
  
  public AutoFitTextView(Context context, AttributeSet attrs) {
      super(context, attrs);
      init();
  }
  
  private void init() {
  
      maxTextSize = this.getTextSize();
      if (maxTextSize &lt; 35) {
          maxTextSize = 30;
      }
      minTextSize = 20;
  }
  
  private void refitText(String text, int textWidth) {
     if (textWidth 0) {
         int availableWidth = textWidth - this.getPaddingLeft()
                 - this.getPaddingRight();
         float trySize = maxTextSize;
  
         this.setTextSize(TypedValue.COMPLEX_UNIT_PX, trySize);
         while ((trySize minTextSize)
                 &amp;&amp; (this.getPaint().measureText(text) availableWidth)) {
             trySize -= 1;
             if (trySize &lt;= minTextSize) {
                 trySize = minTextSize;
                 break;
             }
             this.setTextSize(TypedValue.COMPLEX_UNIT_PX, trySize);
         }
         this.setTextSize(TypedValue.COMPLEX_UNIT_PX, trySize);
     } }
  
  @Override
  protected void onTextChanged(final CharSequence text, final int start, final int before,
          final int after) {
      refitText(text.toString(), this.getWidth());
  }
  
  @Override
  protected void onSizeChanged(int w, int h, int oldw, int oldh) {
      if (w != oldw) {
          refitText(this.getText().toString(), w);
      }
  }
  
  @Override
  protected void onMeasure(int widthMeasureSpec, int heightMeasureSpec) {
      super.onMeasure(widthMeasureSpec, heightMeasureSpec);
      int parentWidth = MeasureSpec.getSize(widthMeasureSpec);
      refitText(this.getText().toString(), parentWidth);
  }
  
  public float getMinTextSize() {
      return minTextSize;
  }
  
  public void setMinTextSize(int minTextSize) {
      this.minTextSize = minTextSize;
  }
  
  public float getMaxTextSize() {
      return maxTextSize;
  }
  
  public void setMaxTextSize(int minTextSize) {
      this.maxTextSize = minTextSize;
  }
  
  private float minTextSize;
  
  private float maxTextSize;
  
  }
