( 转 ) Android自绘字体大小paint.settextsize随分辨率大小变化
- 1.获取当前设备的屏幕大小
-
- DisplayMetrics displayMetrics = new DisplayMetrics();
- this.getWindowManager().getDefaultDisplay().getMetrics(displayMetrics);
-
- 2.计算与你开发时设定的屏幕大小的纵横比(这里假设你开发时定的屏幕大小是480*800)
-
- int screenWidth = displayMetrics.widthPixels;
- int screenHeight = displayMetrics.heightPixels;
- float ratioWidth = (float)screenWidth / 480;
- float ratioHeight = (float)screenHeight / 800;
-
- RATIO = Math.min(ratioWidth, ratioHeight);
- if (ratioWidth != ratioHeight) {
- if (RATIO == ratioWidth) {
- OFFSET_LEFT = 0;
- OFFSET_TOP = Math.round((screenHeight - 800 * RATIO) / 2);
- }else {
- OFFSET_LEFT = Math.round((screenWidth - 480 * RATIO) / 2);
- OFFSET_TOP = 0;
- }
- }
-
- 3.根据上一步计算出来的最小纵横比来确定字体的大小(假定在480*800屏幕下字体大小设定为35)
-
- public static int TEXT_SIZE = Math.round(35 * RATIO);
-
- 4.根据上一步计算的字体大小来设定应用程序中字体的大小
-
- Paint paint = new Paint();
- paint.setTextSize(TEXT_SIZE);
- canvas.drawText("test", 0, 0, paint);
