我有疑问。

如何从使用ImageView功能的数组共享图像？

How can I share images from an Array that uses ImageView feature?

我的数组有超过100张图片，例如：

My array has more than 100 images, an example:

Final int [] photos = {
                R.drawable.abrir_a_boca,
                R.drawable.rooms,
                R.drawable.firmly,
                R.drawable.agradeca,
                R.drawable.alfaiate,
                R.drawable.ancora,
}

要分享我正在尝试使用Intent.ACTION_SEND

To share I'm trying to use Intent.ACTION_SEND

Set.setOnClickListener (new View.OnClickListener () {
            @Override
            Public void onClick (View v)
            {
                Intent sharingIntent = new Intent (Intent.ACTION_SEND);
                Uri screenshotUri = Uri.parse (photos???);

                SharingIntent.setType ("image / *");
                SharingIntent.putExtra (Intent.EXTRA_STREAM, screenshotUri);
                StartActivity (Intent.createChooser (sharingIntent, "Share image using"));

            }
        });

我如何分享图像？

非常感谢你!!!

推荐答案

在分享你的形象之前你必须做一些操作，所以在你的 Manifest.xml ：

You have to do some operations before you share your image, so add the permission in your Manifest.xml:

<uses-permission android:name="android.permission.WRITE_EXTERNAL_STORAGE"/>

拳头，从你的创建位图对象可绘制资源：

Fist, create a Bitmap object from your drawable resource:

Bitmap bitmap= BitmapFactory.decodeResource(getResources(),R.drawable.xxxx);

然后，获取您分享图片的路径

Then, get the path for you share your image

String path = Environment.getExternalStoragePublicDirectory(Environment.DIRECTORY_PICTURES)+"/yourImage.jpg";
OutputStream out = null;
File file=new File(path);
try {
    out = new FileOutputStream(file);
    bitmap.compress(Bitmap.CompressFormat.JPEG, 100, out);
    out.flush();
    out.close();
} catch (Exception e) {
    e.printStackTrace();
}
path=file.getPath();
Uri uri = Uri.parse("file://"+path);

最后，创建你的意图：

Intent intent = new Intent();
intent = new Intent(android.content.Intent.ACTION_SEND);
intent.setFlags(Intent.FLAG_ACTIVITY_NEW_TASK);
intent.putExtra(Intent.EXTRA_STREAM, uri);
intent.setType("image/jpg");
startActivity(Intent.createChooser(intent,"Share with..."));
