问题描述
我正在从XML资源读取矢量图像,并将其显示在ImageView中。 没关系。 现在,我需要使用intent.putExtra将图像传递给Intent。 问题:如何将矢量XML转换为位图或从ImageView获取图像? 我尝试了.getDrawingCache()、. getDrawable,getImageMatrix等,但是它不起作用。
尝试过这种方式:
String path = MediaStore.Images.Media.insertImage(getApplicationContext().getContentResolver(),
imgPrevisao.getDrawingCache(),
"Minha previs?o",null);
Intent sharingIntent = new Intent(Intent.ACTION_SEND);
sharingIntent.setType("image/*");
sharingIntent.putExtra(Intent.EXTRA_STREAM, Uri.parse(path)) ;
getApplicationContext().startActivity(Intent.createChooser(sharingIntent, "Share with"));
这样:
Intent intent = new Intent( Intent.ACTION_SEND );
intent.addFlags(Intent.FLAG_GRANT_READ_URI_PERMISSION);
intent.putExtra( Intent.EXTRA_TEXT, textoPrevisao );
intent.putExtra( Intent.EXTRA_STREAM, imgPrevisao.getDrawingCache() );
intent.setType( "image/*" );
startActivity( intent );
TIA,

一种方法是使用 :
public static Uri getImageUri(Context context, Bitmap bmp) {
String path = MediaStore.Images.Media.insertImage(context.getContentResolver(), , "share_title",bmp ,null);
return Uri.parse(path);
}
然后:
public static void shareImageViewContent(ImageView view) {
Bitmap bitmap = ((BitmapDrawable)view.getDrawable()).getBitmap();
Intent sharingIntent = new Intent(Intent.ACTION_SEND);
sharingIntent.setType("image/jpeg");
sharingIntent.putExtra(Intent.EXTRA_STREAM, getImageUri(bitmap)) ;
context.startActivity(Intent.createChooser(sharingIntent, "Share with"));
}
更复杂的解决方案是使用信用: , ,

我知道那是很久以前的事了,但是如果有人最终有同样的疑问,我希望它能有所帮助。 我想共享图像和文本,因为我无法按照自己的方式进行操作,因此制作了屏幕截图并进行了共享。
private void shareScreenShot() {
try {
// image naming and path to include sd card appending name you choose for file
String mPath = Environment.getExternalStoragePublicDirectory(Environment.DIRECTORY_PICTURES)
.toString()+"/Zodiaco";
// create bitmap screen capture
View v1 = getWindow().getDecorView().getRootView();
v1.setDrawingCacheEnabled(true);
Bitmap bitmap = Bitmap.createBitmap(v1.getDrawingCache());
v1.setDrawingCacheEnabled(false);
//creates the directory
File pasta = new File(mPath);
if (!pasta.exists()) {
pasta.mkdir();
}
//creates the image
File imageFile = new File(mPath+ "/" + getDate() + ".jpg");
FileOutputStream outputStream = new FileOutputStream(imageFile);
if(!imageFile.exists()){
imageFile.createNewFile();
}
int quality = 100;
bitmap.compress(Bitmap.CompressFormat.JPEG, quality, outputStream);
outputStream.flush();
outputStream.close();
Uri uri = Uri.fromFile(imageFile);
// creates the intent and defines its action
Intent intent = new Intent( Intent.ACTION_SEND );
intent.setDataAndType(uri, "image/*");
intent.putExtra(Intent.EXTRA_STREAM, uri);
// inicia a intent
startActivity( intent );
} catch (Throwable e) {
Toast.makeText(this, "N?o foi possível compartilhar a previs?o.",
Toast.LENGTH_LONG).show();
e.printStackTrace();
}
}
