我在应用程序中使用了共享意图,但我无法共享图像和文本,我正在使用我的 json 响应中的图像和文本,但它不起作用.我没有收到任何错误,但是共享方法不起作用。

执行此操作以保存图像。将您的方法替换为此
public Uri getLocalBitmapUri(ImageView imageView) {
imageview.buildDrawingCache();
Bitmap bm = imageview.getDrawingCache();
OutputStream fOut = null;

outputFileUri = Uri.fromFile(imageFile);
fOut = new FileOutputStream(imageFile);
} catch (Exception e) {
e.printStackTrace();
}
try {
