[英]Draw bubble programmatically with arrow
我正在从Stackoverflow实现以下类
https://stackoverflow.com/a/20811323/1936925
但我需要这样的泡沫
我正在尝试很多,但是不知道该怎么做。
为了获得上述可绘制对象,我需要进行哪些编辑。
尝试这个:
public Bitmap overlay(Bitmap image, String content) {
BitmapFactory.Options options = new BitmapFactory.Options();
options.inScaled = false;
options.inPreferredConfig = Bitmap.Config.ARGB_8888;
//My bg bitmap, use yours
Bitmap background = Bitmap.createScaledBitmap(BitmapFactory.decodeResource(MapActivity.context.getResources(), R.drawable.marker_base, options), marker_width, marker_height, true);
//your red bitmap here
Bitmap bmOverlay = Bitmap.createBitmap(background.getWidth(), background.getHeight(), background.getConfig());
Canvas canvas = new Canvas(bmOverlay);
Paint paint = new Paint();
paint.setFilterBitmap(true);
canvas.drawBitmap(background, new Matrix(), paint);
canvas.drawBitmap(image, 3, 3, paint);
if (content != null)
{
//Use your TextSize and Color and paddings
paint = new Paint();
paint.setColor(Color.BLACK);
if (content.length() < 11)
paint.setTextSize(13);
else
paint.setTextSize(10);
//30 / 28, 17 - my paddings
canvas.drawText(content, (content.length() < 11)?30:28, 17, paint);
}
return bmOverlay;
}
解决了
mPointer.rLineTo(80, 0);
mPointer.rLineTo(0, 60);
mPointer.rLineTo(-(80), -60);
mPointer.close();
