嗨,天才!
有什么问题?
我试图在标记前绘制文本。我将获得清晰的位图并绘制文本,但位图仍然清晰 - 文本在哪里?
我试图将视图转换为位图,但这也不是一个好主意。
PS: scale >= 1
mMap.addMarker(new MarkerOptions()
.position(new LatLng(56.83789, 60.5986)) .icon(BitmapDescriptorFactory.fromBitmap(drawTextToBitmap(getApplicationContext(), R.drawable.ic_maps_marker,"19"))));
//here I'm trying to draw text bitmap
public static Bitmap drawTextToBitmap(Context gContext,int gResId,String gText) {
Resources resources = gContext.getResources();
float scale = resources.getDisplayMetrics().density;
Bitmap bitmap =
BitmapFactory.decodeResource(resources, gResId);
android.graphics.Bitmap.Config bitmapConfig =
bitmap.getConfig();
if(bitmapConfig == null) {
bitmapConfig = android.graphics.Bitmap.Config.ARGB_8888;
}
bitmap = bitmap.copy(bitmapConfig, true);
Canvas canvas = new Canvas(bitmap);
Paint paint = new Paint(Paint.ANTI_ALIAS_FLAG);
paint.setColor(Color.BLACK);
paint.setTextSize((int) (14 * scale));
paint.setShadowLayer(1f, 0f, 1f, Color.WHITE);
Rect bounds = new Rect();
paint.getTextBounds(gText, 0, gText.length(), bounds);
int x = (bitmap.getWidth() - bounds.width())/2;
int y = (bitmap.getHeight() + bounds.height())/2;
canvas.drawText(gText, x * scale, y * scale, paint);
return bitmap;
}
