Question

我只需通过Tweet分享图片。

这是我的代码

- (UITableViewCell *)tableView:(UITableView *)tableView cellForRowAtIndexPath:(NSIndexPath *)indexPath
{
     UILabel *inTime = [[UILabel alloc] initWithFrame:CGRectMake(70.0, 12.0, 50.0, 20.0)];
     [inTime setTag:1];
     [inTime setBackgroundColor:[UIColor lightGrayColor]]; // transparent label background
     [inTime setFont:[UIFont boldSystemFontOfSize:11.0]];
     // custom views should be added as subviews of the cell's contentView:
     [cell.contentView addSubview:inTime];

     UILabel *outTime = [[UILabel alloc] initWithFrame:CGRectMake(140.0, 12.0, 50.0, 20.0)];
     [outTime setTag:2];
     [outTime setBackgroundColor:[UIColor lightGrayColor]]; // transparent label background
     [outTime setFont:[UIFont boldSystemFontOfSize:11.0]];
     // custom views should be added as subviews of the cell's contentView:
     [cell.contentView addSubview:outTime];[(UILabel *)[cell.contentView viewWithTag:1] setText:[SlotsAvailable objectAtIndex:indexPath.row]];
     [(UILabel *)[cell.contentView viewWithTag:2] setText:[slot_time_out objectAtIndex:indexPath.row]];
}

我得到了结果：

点击“Android系统”时，Twitter分享弹出窗口：

我想要的是什么：

如何通过Twitter或直接消息通过Twitter分享？
如何更改标题＆amp;共享项目的图标。 Ex Twitter分享项目从“Android系统”到“推特”？

Answer 1

我无法将Tweet和Direct Message都放到前面，但是下面的代码会让你在那里找到一个。实际上你可以把两者都放在前面，但两者都出现了同名“Tweet”所以它的种类无法使用。我还包括facebook，insta和tumblr。要使用com.twitter.android.composer.ComposerActivity替换com.twitter.android.DMActivity，请使用直接消息代替推文。为两者添加另一个'if'用于DMActivity。

不能肯定地说，但我认为您不能更改应用程序包的图标。

List<Intent> targetedShareIntents = new ArrayList<Intent>();
        Intent shareIntent = new Intent(android.content.Intent.ACTION_SEND);
        shareIntent.setType("image/jpeg");//("text/plain");
        Uri uri = Uri.fromFile(outFile);
        shareIntent.putExtra(Intent.EXTRA_STREAM, uri);
        List<ResolveInfo> resInfo = getPackageManager().queryIntentActivities(shareIntent, 0);
        for (ResolveInfo resolveInfo : resInfo) {
            String packageName = resolveInfo.activityInfo.packageName;
            Intent targetedShareIntent = new Intent(android.content.Intent.ACTION_SEND);
            targetedShareIntent.setType("image/jpeg");
            targetedShareIntent.putExtra(Intent.EXTRA_STREAM, uri);
            if(TextUtils.equals(packageName,"com.facebook.katana")|TextUtils.equals(packageName,"com.instagram.android")
                    |TextUtils.equals(packageName,"com.tumblr")) {
                targetedShareIntent.setPackage(packageName);
                targetedShareIntents.add(targetedShareIntent);
            }
            if(TextUtils.equals(resolveInfo.activityInfo.name,"com.twitter.android.composer.ComposerActivity")) {
                targetedShareIntent.setPackage(packageName);
                targetedShareIntent.setClassName(
                        resolveInfo.activityInfo.packageName,
                        resolveInfo.activityInfo.name);
                targetedShareIntents.add(targetedShareIntent);
            }
        }
        Intent chooserIntent = Intent.createChooser(targetedShareIntents.remove(0), "Select app to share");
        chooserIntent.putExtra(Intent.EXTRA_INITIAL_INTENTS, targetedShareIntents.toArray(new Parcelable[]{}));
        startActivity(chooserIntent);

Answer 2

撰写新推文：

public static Intent getTwitterShareIntent(Context context) {
    Intent shareIntent = new Intent(Intent.ACTION_SEND);
    shareIntent.setType("text/plain");
    shareIntent.setFlags(Intent.FLAG_ACTIVITY_NEW_TASK);
    shareIntent.setClassName("com.twitter.android",
            "com.twitter.composer.ComposerShareActivity");
    return shareIntent;
}

Android分享意图Twitter：如何仅通过推文或直接消息分享？
