我正在尝试使用intent共享图像。这是我创建的方法
public void shareImg(int fileNum) //Consider fileNum=R.drawable.img
{
Uri uri= Uri.parse("android.resource://"
+ context.getPackageName() + "/" + fileNum);
Intent share=new Intent();
share.setAction(Intent.ACTION_SEND);
share.setType("image/*");
share.putExtra(Intent.EXTRA_STREAM, uri);
share.putExtra(Intent.EXTRA_TEXT, "Sent Via ---");
Intent chooser= Intent.createChooser(share, "Share Via");
context.startActivity(chooser);
}
图片与带有标题的Whatsapp正确共享。但是,当我尝试与Gmail,Messenger等分享应用时,它会在Toast中显示错误。
例如。
Gmail说:无法附加空文件
Messenger说:无法转换为图片

您可以使用共享意图共享图像,但您必须将图像解码为本地化的位图
Intent intent = new Intent(Intent.ACTION_SEND);
intent.putExtra(Intent.EXTRA_TEXT, "Hey view/download this image");
String path = Images.Media.insertImage(getContentResolver(), loadedImage, "", null);
Uri screenshotUri = Uri.parse(path);
intent.putExtra(Intent.EXTRA_STREAM, screenshotUri);
intent.setType("image/*");
startActivity(Intent.createChooser(intent, "Share image via..."));
loadedImage是图像的路径

以下是您可以执行的步骤。
第1步。首先从drawable
创建位图Drawable d = ImagesArrayList.get(0);
Bitmap bitmap = ((BitmapDrawable)d).getBitmap();
第2步。将位图保存到文件
FileOutputStream out = null;
String filename = Environment.getExternalStorageDirectory() + File.separator + "temporary_file.jpg";
try {
out = new FileOutputStream(filename);
bitmap.compress(Bitmap.CompressFormat.PNG, 100, out); // bmp is your Bitmap instance
// PNG is a lossless format, the compression factor (100) is ignored
} catch (Exception e) {
e.printStackTrace();
} finally {
try {
if (out != null) {
out.close();
}
} catch (IOException e) {
e.printStackTrace();
}
}
第3步。与fileurl共享此图像文件。与共享图库图像共享图像。
完整答案
Bitmap bitmap= BitmapFactory.decodeResource(getResources(),R.drawable.xxxx); // your resource ID here
String path = Environment.getExternalStoragePublicDirectory(Environment.DIRECTORY_PICTURES)+"/LatestShare.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 bmpUri = Uri.parse("file://"+path);
Intent shareIntent = new Intent();
shareIntent = new Intent(android.content.Intent.ACTION_SEND);
shareIntent.setFlags(Intent.FLAG_ACTIVITY_NEW_TASK);
shareIntent.putExtra(Intent.EXTRA_STREAM, bmpUri);
shareIntent.setType("image/jpg");
startActivity(Intent.createChooser(shareIntent,"Share with"));
