android - Activity 自动滚动到中间

Question

当我打开一个 Activity 时，它会自动滚动到中间。当我打开与 Activity 具有相同布局 xml 文件的 fragment 时，它无需滚动即可正常打开。我试着把

   View view=getWindow().getDecorView().findViewById(android.R.id.content);
            view.scrollTo(0,0);

但是没用..为什么我的 Activity 会自动滚动到中间，我该如何调整它以使其在不滚动的情况下打开？

public class TeamDetails extends FragmentActivity {
    ImageView iv1, iv2, iv3;

    @Override
    protected void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.team_details);
        getActionBar().hide();
View view=getWindow().getDecorView().findViewById(android.R.id.content);
        view.scrollTo(0,0);
        view.setVerticalScrollBarEnabled(false);
        Configuration config = getResources().getConfiguration();
        android.support.v4.app.Fragment fragment = null;
        FragmentManager fragmentManager = getFragmentManager();
        final FragmentTransaction fragmentTransaction =
                fragmentManager.beginTransaction();
        String[] web = {
                "     dfg",
                "     fs",
                "     sfdf",
                "     fsdf",
                "     sdfdsf",

        } ;
     int[] mThumbIds = {

        CustomGridSingle adapter = new CustomGridSingle(TeamDetails.this, web, mThumbIds);

        GridView grid = (GridView) findViewById(R.id.gridView);

        grid.setAdapter(adapter);



       iv1 = (ImageView)findViewById(R.id.imageView13);
        iv1.setOnClickListener(new View.OnClickListener() {
            @Override
            public void onClick(View v) {
              finish();
            }
        });
        iv2 = (ImageView) findViewById(R.id.imageView14);
        iv2.setOnClickListener(new View.OnClickListener() {
            @Override
            public void onClick(View v) {
                TeamDetails2 fragment = new TeamDetails2();

                        .add(android.R.id.content, fragment).commit();

            }

                        .add(android.R.id.content, fragment).commit();
            }
        });

    }

    public class ImageAdapter extends BaseAdapter {

Jemshit Iskenderov 的评论让我找到了适用于我的案例的解决方案，即添加

android:focusableInTouchMode="true"

到顶层父级，恰好是一个 RelativeLayout。
