取得Android绘制的图像的绝对路径 [英] Get absolute path of android drawable image

问题描述

我需要得到的绝对路径还是我绘制的图像的android应用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?

绘制对象是如下

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

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

推荐答案

如果您的应用程序是在SD卡insalled尝试这个code：

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);
}
