此解决方案用于通过 TwitPic API 将图像上传到 Twitter。您需要在他们的开发者部分注册您的帐户

我采用的解决方案可以被认为是一个两步解决方案。

首先，当用户点击发布按钮时，我首先抓取图片并上传到 TwitPic。从那里，我获取了 TwitPic ( String url = upload.upload(finalFile);) 返回的 URL。

在此代码的第二步中，在一个 String 实例 ( String finalStatusWithURL) 中，我获取了 an 的内容，EditText然后将步骤 1 中的 URL 附加到它上面。完成此操作后，该帖子最终发布到 Twitter。

Configuration conf = new ConfigurationBuilder()
.setOAuthConsumerKey(TWITTER_CONSUMER_KEY)
.setOAuthConsumerSecret(TWITTER_CONSUMER_SECRET)
.setOAuthAccessToken(twit_access_token)
.setOAuthAccessTokenSecret(twit_access_token_secret)
.setMediaProviderAPIKey(TWIT_PIC_API)
.build();

// SET THE FILE PATH (THIS IS UPDATED! NOTICE THE CHANGES MADE!!)
Uri tempUri = getImageUri(getApplicationContext(), bmpFinal);
File finalFile = new File(getRealPathFromURI(tempUri));

// THIS IS IMPORTANT. TWITPIC NEEDS THE ACTUAL / ABSOLUTE PATH OF THE IMAGE. JUST THE URI DOES NOT WORK!!!!

ImageUpload upload = new ImageUploadFactory(conf).getInstance(MediaProvider.TWITPIC);

String url = upload.upload(finalFile);
Log.e("TWITTER URL RESPONSE", url);

// END OF FIRST STEP:

// SECOND STEP IS TO UPLOAD TO TWITTER

ConfigurationBuilder builder = new ConfigurationBuilder();

builder.setOAuthConsumerKey(YOUR_TWITTER_CONSUMER_KEY);
builder.setOAuthConsumerSecret(YOUR_TWITTER_CONSUMER_SECRET);

AccessToken accessToken = new AccessToken(your_twit_access_token, your_twit_access_token_secret);
Twitter twitter = new TwitterFactory(builder.build()).getInstance(accessToken);

String finalStatusWithURL = null;

if (finalStatusMessage.trim().length() > 0) {

    finalStatusMessage = editStatusUpdate.getText().toString();
    finalStatusWithURL = finalStatusMessage + ":\n " + url;

} else {
    finalStatusWithURL = url;
}

twitter4j.Status response = twitter.updateStatus(finalStatusWithURL);
Log.e("TWITTER RESPONSE", response.getText());

这是获取您要上传的图像的真实路径的方法：

// HELPER METHOD TO GET REAL PATH FOR THE SELECTED IMAGE
public String getRealPathFromURI(Uri uri) {
    Cursor cursor = getContentResolver().query(uri, null, null, null, null); 
    cursor.moveToFirst(); 
    int idx = cursor.getColumnIndex(MediaStore.Images.ImageColumns.DATA); 
    return cursor.getString(idx); 
}

public Uri getImageUri(Context inContext, Bitmap inImage) {
    ByteArrayOutputStream bytes = new ByteArrayOutputStream();
    inImage.compress(Bitmap.CompressFormat.JPEG, 100, bytes);
    String path = Images.Media.insertImage(inContext.getContentResolver(), inImage, "Title", null);
    return Uri.parse(path);
}

更新：

在尝试上传之前执行此操作：

Bitmap bmpFinal = getBitmapFromURL("http://www.cosmopolitanclublahore.com/wp-content/uploads/2011/06/mexicanfoodrestaurant.jpg");

以及返回位图的方法：

// THE METHOD TO DOWNLOAD THE IMAGE INTO A BITMAP
public Bitmap getBitmapFromURL(String strURL) {
    try {
        URL url = new URL(strURL);
        HttpURLConnection connection = (HttpURLConnection) url.openConnection();
        connection.setDoInput(true);
        connection.connect();
        InputStream input = connection.getInputStream();
        Bitmap myBitmap = BitmapFactory.decodeStream(input);
        return myBitmap;
    } catch (IOException e) {
        e.printStackTrace();
        return null;
    }
}

你可能需要调整一些东西。我的代码使用用户从图库中选择的图像或他用相机拍摄的图像。您需要上传从 Internet 上获取的图像。里程可能会有所不同，并且可能需要调整代码。
