Java 删除所选项目列表视图

我试图删除ListView中的选定项，所以我编写了这段代码

@Override
protected void onActivityResult(int requestCode, int resultCode, Intent intent) {
    super.onActivityResult(requestCode, resultCode, intent);
    if(requestCode == 1) {
        try {
            for(int a=0; a<myAdapter.getCustomItemPositions().size(); a++) {
                applicationInfo = getPackageManager().getApplicationInfo(myAdapter.getArrayListPosition().get(a), a);
            }
        } catch(PackageManager.NameNotFoundException e) {
            applicationInfoArrayList.remove(myAdapter.getCustomItemPositions());
            Log.d("Example", "removed items at positions "+myAdapter.getCustomItemPositions());
            myAdapter.notifyDataSetChanged();
            }

    }
    else {

    }
}

@覆盖
ActivityResult上受保护的void（int-requestCode、int-resultCode、Intent-Intent）{
super.onActivityResult（请求代码、结果代码、意图）；
if（requestCode==1）{
试一试{
对于（int a=0；a请尝试直接从适配器中删除该项：

adapter.remove(adapter.getItem(position));
