我的SD卡中有多个vcf文件.我想将这些vcf文件导入我的联系人.

我使用以下代码:

File file = new File(storage_path);
        Intent intent = new Intent(Intent.ACTION_VIEW);
        intent.setDataAndType(Uri.fromFile(file), "text/x-vcard");
        startActivity(intent);

通过使用上面的代码,我无法一次导入一个vcf文件.我想一次导入多个vcf文件.通过使用上面的代码我也得到重复的联系人.

除了意图之外,还有其他有效的方法来导入联系人吗？谢谢.

如何删除或更改edittext中的搜索视图图标？我正在使用Appcompat库.

我使用下面的代码来修改和删除但它不起作用:

SearchManager searchManager = (SearchManager) getSystemService(Context.SEARCH_SERVICE);
        searchView.setSearchableInfo(searchManager.getSearchableInfo(getComponentName()));
    View search_mag_icon = (View)searchView.findViewById(android.support.v7.appcompat.R.id.search_mag_icon);
        search_mag_icon.setBackgroundResource(R.drawable.ic_stub);
        //search_mag_icon.setVisibility(View.GONE);
