Question

我的代码看起来像这样：

    case 2:
            final TextView scoretext = new TextView (this);
            return new AlertDialog.Builder(this)
            .setIcon(R.drawable.ic_launcher)
            .setTitle("How cold or hot do you feel today?")
            .setView(qolscorelayout)
            .setPositiveButton("Confirm",
                new DialogInterface.OnClickListener() {
                    public void onClick(DialogInterface dialog, int whichButton)
                    {
                        SeekBar qolDialogSeekbar = (SeekBar)qolscorelayout.findViewById(R.id.qolscore_seekbar);
                        todayScore = qolDialogSeekbar.getProgress();
                        showDialog(3);
                    }
                }
            ).create();

qolscorelayout在前面定义为：

    qolscorelayout = inflater.inflate(R.layout.qolscore_dialog, (ViewGroup)findViewById(R.id.qolscore_dialog_root_element)); //Layout for getting Seekbar in Dialog

我想在对话框中找到一个TextView，就在滑块上方。

我正在考虑做类似的事情：

    case 2:
            final TextView scoretext = new TextView (this); //NEW
            return new AlertDialog.Builder(this)
            .setIcon(R.drawable.ic_launcher)
            .setTitle("How cold or hot do you feel today?")
            .setView(qolscorelayout)
            .setPositiveButton("Confirm",
                new DialogInterface.OnClickListener() {
                    public void onClick(DialogInterface dialog, int whichButton)
                    {
                        SeekBar qolDialogSeekbar = (SeekBar)qolscorelayout.findViewById(R.id.qolscore_seekbar);
                        todayScore = qolDialogSeekbar.getProgress();
                        scoretext.setText("" + todayScore); //NEW
                        showDialog(3);
                    }
                }
            ).create();

但是如何让它将TextView放在对话框中呢？

Answer 1

只是添加已经说过的内容。

将textview放在qolscore_layout中。然后你可以像这样修改它的内容：

qolscorelayout = inflater.inflate(R.layout.qolscore_dialog, (ViewGroup)findViewById(R.id.qolscore_dialog_root_element));
final TextView scoretext = (TextView) qolscorelayout.findViewById(R.id.scoretext);
scoretext.setText("" + todayScore); //NEW

Android textview在'返回新'alertdialog中
