小编Sel*_*pan的帖子

我已下载Android Studio并开始将其用于我的Android开发.

我需要知道,如何在像Eclipse这样的单一窗口中打开多个项目.期待一些帮助,谢谢.

我想在图像视图中共享图像.但我不想保存到SD卡.但是,当我使用Intent分享我使用过的代码时

Intent share = new Intent(Intent.ACTION_SEND);
                share.setType("image/jpeg");
                share.putExtra(Intent.EXTRA_STREAM,Uri.parse(path));
                startActivity(Intent.createChooser(share, "Share Image"));  

这里路径指定了SD卡中图像的位置

但我不想保存图像...有可能..

我想在数组列表选择位置删除项目

我的代码是

    List<String> historylist = Arrays.asList(history);
    if (historylist.size()>=3){
        System.out.print("*************************************************");
        Log.i(MyContants.StoredHistory_TAG,"StoredHistory size========="+ String.valueOf(historylist.size()));
        String removePosition=historylist.get(2);
        historylist.remove(removePosition);
    }

但是我得到了一个Exception UnsupportedOperationException

错误
