TextView

动态设置字体大小：textView.setTextSize(TypedValue.COMPLEX_UNIT_SP, 20);//设置字体为sp格式

 

 

public class BaselineTextView extends TextView {

    public BaselineTextView(Context context, AttributeSet attrs) {
        super(context, attrs);
    }

    @Override
    protected void onDraw(Canvas canvas) {
        int yOffset = getHeight() - getBaseline();
        canvas.translate(0, yOffset);
        super.onDraw(canvas);
    }

}
