在 android 中使用 Intent 将图像分享到另一个应用
Share image to another app using Intent in android
我想将图像和文本分享到另一个应用程序,但我在使用此代码时遇到文件格式不受支持的问题,请帮助...
Uri picUri = Uri.parse("http://www.planwallpaper.com/static/images/image-slider-2.jpg");
Intent shareIntent = new Intent();
shareIntent.setAction(android.content.Intent.ACTION_SEND);
shareIntent.putExtra(Intent.EXTRA_TEXT, "Hi There...");
shareIntent.putExtra(android.content.Intent.EXTRA_STREAM, picUri);
shareIntent.setType("*/*");
startActivity(Intent.createChooser(shareIntent, "Share Image...."));
The documentation for EXTRA_STREAM
说 Uri
需要有一个 content
方案。 file
通常也有效,至少在 Android 6.0 及更早版本上是这样。很少有应用会期望 http
URL.
试试这个
private class myTask extends AsyncTask<Void, Void, Bitmap> {
protected Bitmap doInBackground(Void... params) {
Bitmap myBitmap=null;
try {
URL url = new URL(src);
HttpURLConnection connection = (HttpURLConnection) url.openConnection();
connection.setDoInput(true);
connection.connect();
InputStream input = connection.getInputStream();
myBitmap = BitmapFactory.decodeStream(input);
} catch (IOException e) {
// Log exception
}
return myBitmap;
}
@Override
protected void onPostExecute(Bitmap result) {
//do stuff
}
}
Bitmap returned_bitmap = new myTask().execute().get()
Intent intent = new Intent(Intent.ACTION_SEND);
intent.putExtra(Intent.EXTRA_TEXT, "download this image");
String bitmapPath = Images.Media.insertImage(getContentResolver(), returned_bitmap,"title", null);
Uri bitmapUri = Uri.parse(bitmapPath);
intent.putExtra(Intent.EXTRA_STREAM, bitmapUri);
intent.setType("image/*");
startActivity(Intent.createChooser(intent, "Share image via..."));
