我如何保存的ImageView作为图像？ [英] How do I save an ImageView as an image?

问题描述

我有一个共享意图的ImageView的（它的伟大工程，使所有的应用程序，我可以将影像分享的），但是，我不能共享的照片，因为它在我的手机没有路径。我该如何去拯救ImageView的我的手机上？下面是我的code。

I have an ImageView with a share intent( which works great, brings up all the apps I can share the image with), however, I can not share the photo because it has no path on my phone. How do I go about saving the ImageView on my phone? Below is my code.

 public void taptoshare(View v)
{  
    View content = findViewById(R.id.myimage);
    content.setDrawingCacheEnabled(true);
        Bitmap bitmap = content.getDrawingCache();
        File file = new File("/DCIM/Camera/image.jpg");
        try 
        {
            file.createNewFile();
            FileOutputStream ostream = new FileOutputStream(file);
            bitmap.compress(CompressFormat.JPEG, 100, ostream);
            ostream.close();
        } 
        catch (Exception e) 
        {
            e.printStackTrace();
        }


    Intent shareIntent = new Intent(Intent.ACTION_SEND);
    Uri phototUri = Uri.parse("/DCIM/Camera/image.jpg");
    shareIntent.setData(phototUri);
    shareIntent.setType("image/*");
    shareIntent.putExtra(Intent.EXTRA_STREAM, phototUri);
    startActivity(Intent.createChooser(shareIntent, "Share Via"));

}   
}

更新 好了，我理解了它。现在我有一个新的问题，我怎么会去拯救这个图片给新文件夹？

UPDATE Ok, so I figured it out. Now I have a new question, how would I go about saving this image to a new folder?

推荐答案

在保存和加载，你需要得到系统的根路径，第一个。这就是我想要做的。

When saving and loading, you need to get the root path of the system, first. This is how I'd do it.

File root = Environment.getExternalStorageDirectory();
File cachePath = new File(root.getAbsolutePath() + "/DCIM/Camera/image.jpg");
