[英]Android Studio - Get tweet image from twitter - Fabric
I have found what looks like an array of bytes, but when I attempt to decode it using bitmaps decodeByteArray, it returns null我发现了一个看起来像字节数组的东西,但是当我尝试使用位图 decodeByteArray 对其进行解码时,它返回 null
String mediaString = t.entities.media.toString();
String[] mediaArray = mediaString.split("(?=@)");
byte[] mediaBytes = mediaArray[1].getBytes();
can anybody help me find a way to retrieve the image so I can display it?谁能帮我找到一种方法来检索图像,以便我可以显示它?
Image url图片网址
String mediaImageUrl = tweet.entities.media.get(0).url;
Bitmap mediaImage = getBitmapFromURL(mediaImageUrl);
Bitmap mImage = null;
Decode the image解码图像
private Bitmap getBitmapFromURL(final String mediaImageUrl) {
try {
Thread t = new Thread() {
public void run() {
try {
URL url = new URL(mediaImageUrl);
HttpURLConnection connection = (HttpURLConnection) url.openConnection();
connection.setDoInput(true);
connection.connect();
InputStream input = connection.getInputStream();
BitmapFactory.Options options = new BitmapFactory.Options();
options.inScaled = false;
mImage = BitmapFactory.decodeStream(input, null, options);
} catch (Exception e) {
e.printStackTrace();
}
}
};
t.start();
} catch (Exception e) {
e.printStackTrace();
}
return mImage;
}
i am getting image only if it is available like:我只在图像可用时获取图像,例如:
String mediaImageUrl = null;
if (tweet.entities.media != null) {
String type = tweet.entities.media.get(0).type;
if (type.equals("photo")) {
mediaImageUrl = tweet.entities.media.get(0).mediaUrl;
}
else {
mediaImageUrl = "'";
}
System.out.println("mediaImageUrl" + mediaImageUrl);
}
If u using type attributes u can easily differentiates image/video from userTimeLine如果您使用类型属性,您可以轻松地将图像/视频与 userTimeLine 区分开来
