[英]How can I tweet texts and images from an Android App in Kotlin?
I would like to tweet text and image from an Android App.我想从 Android 应用程序中发送文本和图像。
I was able to put an image to tweet on a screen of app and the app can open tweet form via a button.我能够在应用程序的屏幕上放置要推文的图像,该应用程序可以通过按钮打开推文表单。
As a reference, I checked the following former question.作为参考,我检查了以下前一个问题。
How to Share Image + Text together using ACTION_SEND in android? 如何在android中使用ACTION_SEND一起共享图像+文本?
Problem is set text and image data on the program are not appeared to the twitter.问题是程序上设置的文本和图像数据没有出现在推特上。
It only show blank tweet form.它只显示空白的推文表格。
How can I move these text and image from the Android app to the tweet form?如何将这些文本和图像从 Android 应用程序移动到推文表单?

I tried to use share compat
instead of intent
, but it didn't work neither.我尝试使用
share compat
而不是intent
,但它也不起作用。
In addition to that, share compat
is only available for user who have downloaded Twitter app on the phones, so I prefer to use intent
to tweet text and image from the Android app.除此之外,
share compat
仅适用于在手机上下载了 Twitter 应用程序的用户,因此我更喜欢使用intent
从 Android 应用程序中发送文本和图像。
The image is located on app/assets/sample.jpg
.该图像位于
app/assets/sample.jpg
。
