Android中带有EditText问题的Popup中的ListView

我遇到了在Popup中滚动ListView的问题。我有一个具有对话框主题的活动，以便它可以作为弹出窗口打开。 Popup应在底部包含EditText，其上方的剩余区域应为ListView。当活动开始时，它应该从键盘打开＆amp;专注于EditText。

问题：当键盘打开时，ListView不会滚动。

以下是我的活动代码：

public class CommentsActivity extends Activity{
private InputMethodManager imm;
private String commentCount;
private ShopPirateDatabase db;
private ArrayList<CommentsBean> commentsList = new ArrayList<CommentsBean>();
@Override

protected void onCreate(Bundle savedInstanceState) {
 super.onCreate(savedInstanceState);
 setContentView(R.layout.comments_layout);
 imm = (InputMethodManager) this
            .getSystemService(Context.INPUT_METHOD_SERVICE);
 db=new ShopPirateDatabase(this);
 if(getIntent().hasExtra("count")){
        commentCount=getIntent().getExtras().getString("count");
    }
 ListView lvMyComments=(ListView)findViewById(R.id.lvMyComments);
 lvMyComments.setVisibility(View.GONE);
 final Button btnPost=(Button)findViewById(R.id.btnPost);
 btnPost.setVisibility(View.GONE);
 etAddComment=(EditText)findViewById(R.id.etAddComment);
 RelativeLayout progressLayout=(RelativeLayout)findViewById(R.id.progressLayout);
 progressLayout.setVisibility(View.VISIBLE);
 TextView tvNoComments=(TextView)findViewById(R.id.tvNoComments);
 tvNoComments.setVisibility(View.GONE);
 imm.showSoftInput(etAddComment, InputMethodManager.SHOW_IMPLICIT);
 if(Integer.parseInt(commentCount) > 0){
        getCommentsFromDb();
        if(commentsList!=null && commentsList.size() > 0){
            progressLayout.setVisibility(View.GONE);
            tvNoComments.setVisibility(View.GONE);
            lvMyComments.setVisibility(View.VISIBLE);
            CommentsAdapter commentsAdapter = new CommentsAdapter(
                    CommentsActivity.this, commentsList);
            lvMyComments.setAdapter(commentsAdapter);
        }
    } else{
        progressLayout.setVisibility(View.GONE);
        tvNoComments.setVisibility(View.VISIBLE);
        lvMyComments.setVisibility(View.GONE);
    }
}
private void getCommentsFromDb() {
    db.openDatabase();
    Cursor c = db.getComments();
    if (c != null) {
        commentsList = null;
        commentsList = new ArrayList<CommentsBean>();

        if (c.moveToFirst()) {
            do {

                CommentsBean mBeanClass = new CommentsBean();
                mBeanClass
                        .setCommentText(c.getString(c
                                .getColumnIndex(db.KEY_COMMENT_TEXT)));
                mBeanClass
                        .setCommentedDate(c.getString(c
                                .getColumnIndex(db.KEY_COMMENT_DATE)));
                mBeanClass
                        .setCommentedBy(c.getString(c
                                .getColumnIndex(db.KEY_COMMENT_USER)));

                commentsList.add(mBeanClass);
            } while (c.moveToNext());
        }
    }
    c.close();
    db.closeDatabase();
   }
}
