获取android可绘制图像的绝对路径 [英] Get absolute path of android drawable image

问题描述

我需要在 android 应用程序中获取我的可绘制图像的绝对路径或 File 对象.有没有办法做到这一点?

I need to get the absolute path or the File object of my drawable image in android application. Is there any way to do this?

Drawable 如下

Drawable is as following

context.getResources().getDrawable(R.drawable.back_button)

context.getResources().getDrawable(R.drawable.back_button)

推荐答案

如果您的应用安装在 sdcard 上，请尝试以下代码:

If you app is insalled on sdcard try this code :

Bitmap bitMap = BitmapFactory.decodeResource(getResources(),R.id.img1);

File mFile1 = Environment.getExternalStorageDirectory();

String fileName ="img1.jpg";

File mFile2 = new File(mFile1,fileName);
try {
       FileOutputStream outStream;

       outStream = new FileOutputStream(mFile2);

       bitmap.compress(Bitmap.CompressFormat.JPEG, 100, outStream);

       outStream.flush();

       outStream.close();

} catch (FileNotFoundException e) {
       // TODO Auto-generated catch block
       e.printStackTrace();
} catch (IOException e) {
       // TODO Auto-generated catch block
       e.printStackTrace();
}

String sdPath = mFile1.getAbsolutePath().toString()+"/"+fileName;

Log.i("hiya", "Your IMAGE ABSOLUTE PATH:-"+sdPath); 

File temp=new File(sdPath);

if(!temp.exists()){
       Log.e("file","no image file at location :"+sdPath);
}
