Question

我正在尝试动态地实现Radio Group，但是我收到一条错误，说“孩子已经在父级上有一个父调用removeView（）”。以下是我的代码：

RadioGroup rg = new RadioGroup(getContext());
        RadioButton[] allSongsRadio = new RadioButton[countOfAllSongs];

        ArrayList<String> allSongsInMap = new ArrayList<>(countOfAllSongs);
        for(final String eachMood : allSongs.keySet()) {
            for(String eachSong : allSongs.get(eachMood)) {
                allSongsInMap.add(eachMood+" : "+eachSong);
            }
        }

        for(int i=0;i<allSongsInMap.size();i++){
            final String eachSong = allSongsInMap.get(i);
            LinearLayout playButtonAndSeekBar = new LinearLayout(getContext());
            final FloatingActionButton playButton = new FloatingActionButton(getContext());
            playButton.setBackgroundTintList(ColorStateList.valueOf(Color.WHITE));
            playButton.setImageResource(R.drawable.play);
            playButton.setSize(FloatingActionButton.SIZE_MINI);
            playButton.setId(++playButtonId);
            SeekBar seekBarForEachSong = new SeekBar(getContext());
            layoutDetails = new LinearLayout.LayoutParams(LinearLayout.LayoutParams.MATCH_PARENT, LinearLayout.LayoutParams.WRAP_CONTENT);
            layoutDetails.rightMargin = 50;
            seekBarForEachSong.setLayoutParams(layoutDetails);
            allSongsRadio[i] = new RadioButton(getContext());
            playButtonAndSeekBar.addView(allSongsRadio[i]);
            playButtonAndSeekBar.addView(playButton);
            playButtonAndSeekBar.addView(seekBarForEachSong);

            eachSongPanel.addView(playButtonAndSeekBar);
            rg.addView(allSongsRadio[i]);
            dialogContainer.addView(eachSongPanel);
        }
        dialogContainer.addView(rg);

    }

需要帮助的人。

您看到此错误导致您将相同的组件添加到ViewGroup中不允许的两个Android中（每个元素属于一个ViewGroup Parent），您正在这样做：

首先，您要在此处添加单选按钮：

playButtonAndSeekBar.addView(allSongsRadio[i]);

然后你将它添加到广播组：

rg.addView(allSongsRadio[i]);

此时allSongsRadio[i]属于playButtonAndSeekBar，您无法将其添加到另一个ViewGroup。

要纠正您的代码，只需将按钮添加到广播组，然后最后将整个广播组添加到playButtonAndSeekBar，以了解您所需的设计。
