android 显示listVIew按后退键闪动不退出当前activity问题

Android，我有一个activity中，主要就是有一个ListView布局，用来加载网络获取的数据，没有图片，都是文字。当listView加载完毕后，我按手机后退键，当前activity闪动一下回到了listView的顶部，也不是报错，后台log也不会报错。有时候会发生，又时候不会！哪位大神知道这个应该是哪一方面的问题！谢谢了。。。

可以把你的代码放出来让我们看下么？不然这样真的很束手

这需要看代码了，你是获取返回键做listview回到顶部处理了吗？

activity代码

public class OrganizationSelectActivity extends Activity {
private OrganizationAdapter adapter;
private List organizationList = new ArrayList<>();
private ListView listView;
private ImageView back;
private Intent intent;

@Override
protected void onCreate(Bundle savedInstanceState) {
    super.onCreate(savedInstanceState);
    this.requestWindowFeature(Window.FEATURE_NO_TITLE);
    setContentView(R.layout.activity_organization_select);
    initView();
    adapter = new OrganizationAdapter(OrganizationSelectActivity.this, organizationList, listView);
    listView.setAdapter(adapter);
}

private void initView() {
    intent = getIntent();
    // 接受传递过来的list
    Bundle bundle = new Bundle();
    bundle = intent.getExtras();
    organizationList = bundle.getParcelableArrayList("list");//这个是上层页面通过Intent传递过来的数据。获取数据没有问题
    listView = (ListView) findViewById(R.id.listView);
    listView.setOnItemClickListener(itemClickListener);
    back = (ImageView) findViewById(R.id.back);
    back.setOnClickListener(new OnClickListener() {
        @Override
        public void onClick(View v) {
            // 回退图标
            finish();
        }
    });
}

// item点击事件
OnItemClickListener itemClickListener = new OnItemClickListener() {

    @Override
    public void onItemClick(AdapterView<?> parent, View view, int position, long id) {
        Bundle bundle = new Bundle();
        bundle.putParcelable("bean", organizationList.get(position));
        intent.putExtras(bundle);
        setResult(RESULT_OK, intent);
        OrganizationSelectActivity.this.finish();
    }
};

}

注意规范，acitivty名.this.finish

重写OnKeyDown:

  @Override
public boolean onKeyDown(int keyCode, KeyEvent event) {
    if (keyCode == KeyEvent.KEYCODE_BACK
            && event.getAction() == KeyEvent.ACTION_DOWN) {
        finish();
    }
    return super.onKeyDown(keyCode, event);
}

    这样应该可以解决
