将可绘制的Android矢量转换为启动器图标PNG [英] Convert Android vector drawable to launcher icon PNG

问题描述

我已将Android启动器图标设置为矢量，但发现应该使用PNG而不是vector(XML).如何将矢量图像转换为启动器图标的PNG.

I've made Android launcher icon as vector but I found out that I should use PNGs instead of vector(XML). How can I convert my vector image to PNGs for launcher icon.

如果有帮助，这是向量:

This is vector if it's of any help:

推荐答案

所有您需要做的是:

1. 在ImageView中渲染矢量
2. 从ImageView获取位图
3. 将位图保存到PNG文件

在ImageView中渲染矢量:

render the Vector in an ImageView:

//--------------------------------------------------------------------------------
    ImageView image = R.findViewById(R.id.imageView);//get ImageView
//--------------------------------------------------------------------------------

从ImageView获取位图:

get the Bitmap from the ImageView:

//--------------------------------------------------------------------------------
    Bitmap bitmap = ((BitmapDrawable)image.getDrawable()).getBitmap();//get Bitmap
    SaveImage(bitmap,"my_png_file");//save it
//--------------------------------------------------------------------------------

将位图保存到PNG文件:

Save the Bitmap to a PNG file:

//--------------------------------------------------------------------------------
    private void SaveImage(Bitmap finalBitmap, String filename)
    {
           String root = Environment.getExternalStorageDirectory().toString();
           File myDir = new File(root + "/saved_images");
           myDir.mkdirs();
           Random generator = new Random();
           int n = 10000;
           n = generator.nextInt(n);

           String fname = filename +".png";
           File file = new File (myDir, fname);
           if (file.exists ()) file.delete ();
           try {
               FileOutputStream out = new FileOutputStream(file);
               finalBitmap.compress(Bitmap.CompressFormat.PNG, 100, out);
               out.flush();
               out.close();
               sendBroadcast(new Intent(
                   Intent.ACTION_MEDIA_MOUNTED,
                   Uri.parse("file://" + Environment.getExternalStorageDirectory())));

           } catch (Exception e) {
               e.printStackTrace();
           }
    }//SaveImage
    //--------------------------------------------------------------------------------
