你不能在android应用程序之间共享GIF,因为没有相应的协议。 对不起,朋友
如果您想在为您构建的应用程序之间共享,您可以序列化图像和标志标题或其他参数,以知道它是gif 如果您的GIF图像在web上
whatsapp.setOnClickListener(new View.OnClickListener() {
@Override
public void onClick(View v) {
Intent whatsappIntent = new Intent(Intent.ACTION_SEND);
whatsappIntent.setFlags(FLAG_ACTIVITY_NEW_TASK);
whatsappIntent.setType("image/*");
whatsappIntent.setPackage("com.whatsapp");
new Download_GIF(image).execute();
Uri imageUri = Uri.parse("file:///storage/emulated/0/downloadedFile.gif");
whatsappIntent.putExtra(Intent.EXTRA_STREAM, imageUri);
try {
startActivity(whatsappIntent);
} catch (android.content.ActivityNotFoundException ex) {
try {
Intent intent = new Intent(Intent.ACTION_VIEW);
intent.setData(Uri.parse("market://details?id=com.whatsapp"));
startActivity(intent);
} catch (Exception e) {
Intent intent = new Intent(Intent.ACTION_VIEW);
intent.setData(Uri.parse("https://play.google.com/store/apps/details?id=com.whatsapp"));
intent.setFlags(FLAG_ACTIVITY_NEW_TASK);
startActivity(intent);
}
}
}
});
这里whatsapp是imageButton
下载

@Tomm发生了什么事???你能帮我吗?你打开我发送的链接了吗here@Tomm那是什么意思???你想说什么?你尝试使用内容提供商了吗?没有@MaximTsybanov,但我如何使用它???你知道吗?需要先保存图像然后再共享吗???现在我从网络上的一些apiyou图像获取gif图像的url?或者在本地存储中?如果您的gif在网上,您需要先下载,然后才能共享,但我不知道如何保存gif图像,如果是jpeg或png等,我们可以通过位图进行保存,但我不知道如何保存gif??我已经回答了如何保存和共享gif
