如何将 ImageView 保存为图像?

问题描述

我有一个带有共享意图的 ImageView(效果很好，显示了我可以共享图像的所有应用程序)，但是，我无法共享照片，因为它在我的手机上没有路径.如何在手机上保存 ImageView?下面是我的代码.

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"));

}   
}

更新好的，所以我想通了.现在我有一个新问题，我将如何将此图像保存到新文件夹?

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

在保存和加载的时候，需要先获取系统的根路径.我就是这样做的.

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");
