问题描述
我有我已经保存在外部存储的位图。我已经有负载和返回位图的方法。我的问题是,我怎么这个图像附加到电子邮件的意图。
注:我知道如何启动电子邮件的意图,我只需要知道如何安装位图。谢谢你。
这是怎么了保存图:
私人无效savePicture(字符串文件名,位图B,上下文CTX){
尝试{
FileOutputStream中出;
OUT = ctx.openFileOutput(文件名,Context.MODE_WORLD_READABLE); b.com preSS(Bitmap.Com pressFormat.JPEG,40出);
如果(b.com preSS(Bitmap.Com pressFormat.JPEG,40出)==真)
out.close();
}赶上(例外五){
e.printStackTrace();
}
}
解决方案
尝试一下本作将电缆带有电子邮件图像
获取图像从SD卡
字符串路径= Environment.getExternalStorageDirectory()的toString()。
档案文件=新的文件(路径,YourImageName.JPEG);
乌里pngUri = Uri.fromFile(文件);
电子邮件意图
意图emailIntent =新意图(android.content.Intent.ACTION_SEND);
emailIntent.setType(text / html的);
emailIntent.putExtra(android.content.Intent.EXTRA_STREAM,pngUri);
I have a bitmap that I have saved in the external storage. I already have a method that loads and returns the bitmap. My question is, how do I attach this image to an email Intent.
Note: I know how to start the email intent, I simply need to know how to attach the bitmap. Thanks.
This is how I am saving the pic:
private void savePicture(String filename, Bitmap b, Context ctx) {
try {
FileOutputStream out;
out = ctx.openFileOutput(filename, Context.MODE_WORLD_READABLE);
b.compress(Bitmap.CompressFormat.JPEG, 40, out);
if (b.compress(Bitmap.CompressFormat.JPEG, 40, out) == true)
out.close();
} catch (Exception e) {
e.printStackTrace();
}
}
解决方案
try this for Attach Image with Email
Fetch Image From SdCard
String path = Environment.getExternalStorageDirectory().toString();
File file = new File(path,"YourImageName.JPEG");
Uri pngUri = Uri.fromFile(file);
Email Intent

emailIntent.setType("text/html");
emailIntent.putExtra(android.content.Intent.EXTRA_STREAM, pngUri);
