Question

I have this code

void drawText2(Canvas c)
    {       

        DisplayMetrics metrics = new DisplayMetrics();
        Display display = ((WindowManager) getSystemService(WINDOW_SERVICE)).getDefaultDisplay();
        display.getMetrics(metrics);

        int screenwidth = metrics.widthPixels;
        int screenheight = metrics.heightPixels;



            Paint paint = new Paint();
            paint.setStyle(Paint.Style.FILL);
            paint.setColor(Color.BLACK);
            paint.setTextSize(150);
            paint.setAntiAlias(true);
            paint.setTypeface(Typeface.DEFAULT_BOLD);

            Bitmap.createBitmap(100, 100, Bitmap.Config.RGB_565);
            float x = screenwidth/2;
            float y = screenheight/2;
            c.drawText("32", x, y, paint);

    }

Which works fine, but if I add in the following line

Typeface GC=Typeface.createFromAsset(getAssets(),"fonts/ADarling.ttf");

as well as change the line

paint.setTypeface(Typeface.DEFAULT_BOLD);

to

paint.setTypeface(Typeface.create(GC, 0));

It will use the font and everything seems to be working fine, but randomly the wallpaper will go black, and stay that way for a few minutes then it will appear again, and will continue to do this. Am I using the code wrong?

Answer 1

Try to initialize the font once only(do not load it everytime drawText2() called)

private Typeface myFont;


public myConstructor() {  
    /* ... */  
    Typeface GC = Typeface.createFromAsset(getAssets(),"fonts/ADarling.ttf");  
    myFont = Typeface.create(GC, Typeface.NORMAL);
    /* ... */  
}

void drawText2(Canvas c)
    /* ... */  
    paint.setTypeface(myFont);
    /* ... */
}

Also the following line is not needed:

Bitmap.createBitmap(100, 100, Bitmap.Config.RGB_565);
