如何共享图像+;android中使用共享意图的文本
我使用这个代码,但它不能正常工作如何共享图像+;android中使用共享意图的文本,android,Android,我使用这个代码,但它不能正常工作 String Body = "Deals Name: " + Bussinessname + "\n" + "Deals: " + deal + "\n" + "Address: " + city + " ," + country; Intent share = new Intent(android.content.Intent.ACTION_SEND); Uri screenshotUri = Uri.parse(Images.Media.
String Body = "Deals Name: " + Bussinessname + "\n"
+ "Deals: " + deal + "\n" + "Address: " + city
+ " ," + country;
Intent share = new Intent(android.content.Intent.ACTION_SEND);
Uri screenshotUri = Uri.parse(Images.Media.EXTERNAL_CONTENT_URI + "/" + image);
share.setType("image/*");
share.putExtra(Intent.EXTRA_SUBJECT, "The EssexPass");
share.putExtra(Intent.EXTRA_TEXT, Body);
share.putExtra(Intent.EXTRA_STREAM, screenshotUri);
startActivity(Intent.createChooser(share, "Share Deal"));
当我使用类型文本时,它会正常工作。但是我想共享一个文本和一个图像。
而且共享意图在FaceBook上不起作用。你可以在 示例代码
Intent shareIntent = new Intent();
shareIntent.setAction(Intent.ACTION_SEND);
shareIntent.putExtra(Intent.EXTRA_STREAM, uriToImage);
shareIntent.setType("image/jpeg");
startActivity(Intent.createChooser(shareIntent, getResources().getText(R.string.send_to)));
请尝试以下代码:
String fileName = "image-3116.jpg";//Name of an image
String externalStorageDirectory = Environment.getExternalStorageDirectory().toString();
String myDir = externalStorageDirectory + "/saved_images/"; // the file will be in saved_images
Uri uri = Uri.parse("file:///" + myDir + fileName);
Intent shareIntent = new Intent(android.content.Intent.ACTION_SEND);
shareIntent.setType("text/html");
shareIntent.putExtra(android.content.Intent.EXTRA_SUBJECT, "Test Mail");
shareIntent.putExtra(android.content.Intent.EXTRA_TEXT, "Launcher");
shareIntent.putExtra(Intent.EXTRA_STREAM, uri);
startActivity(Intent.createChooser(shareIntent, "Share Deal"));
您需要在意向中添加额外的内容:
intent.putExtra("extra_name_1", ”some value”);
intent.putExtra("extra_name_2", 123);
intent.putExtra("extra_name_3”, false);
您好,首先您需要在您的build gradle中添加
编译com.facebook.android:facebook android sdk:4.0.0
,然后按照此链接进行操作。
使用意向过滤器,我们无法在facebook上同时共享文本和图像。如果您想共享图像和文本,则必须创建图像+文本的位图 在此处下载源代码() MainActivity.java

是的,它将不适用于facebook,因为facebook的政策规定,
API不支持为用户预填充消息
您需要使用facebook SDK来完成可能的重复,您是否尝试过设置类型和操作@HardikParmari没有收到任何错误,但当我点击gmail时,gmail的时间是强制关闭的,在什么情况下,它不会像那样发送你的文本抱歉,它工作正常,但在gmail中不是正确的方式,它的图像没有加载。而且什么是不显示的,并且在只上传的hike图像中…当chooser启动时,我不认为Facebook是提供商。您没有注意到uriToImage
,它是您要发送的图像的路径。可绘制图像和图像url呢?我们如何共享它?解释一下可绘制图像
和图像url
