Question

我建立了一个类似于图像的应用程序我想要点击播放器boutton只有medi女巫附加到seekbar开始玩像whatsapp信使。它的工作完美但我的listView在其他列表项上滚动了seekBar进度。我不知道为什么！我从5天开始尝试一切，但我尝试的一切都不起作用。你能帮帮我吗？谢谢大家的帮助。

如有必要，我会发布我的源代码。

我的自定义视图代码如下：

    public class VoiceItemView extends MessageBaseItemView<VoiceItemModel>
        {

    View view;
    private SeekBar audioSeekbar;
    private ImageButton audioControls;
    private TextView link;
    private VoiceRecord mVoiceRecord;
    private MediaPlayer mPlayer = null;
    private TalkActivity talkActivity = new TalkActivity();
    private Handler mHandler;
    private OnAudioFocusChangeListener focusChangeListener =
        new OnAudioFocusChangeListener() {
            public void onAudioFocusChange(int focusChange) {
                switch (focusChange) {
                case (AudioManager.AUDIOFOCUS_LOSS_TRANSIENT_CAN_DUCK) :
                    mPlayer.setVolume(0.2f, 0.2f);
                break;

                case (AudioManager.AUDIOFOCUS_LOSS_TRANSIENT) :
                    mPlayer.pause();
                break;

                case (AudioManager.AUDIOFOCUS_LOSS) :
                    mPlayer.pause();
                break;

                case (AudioManager.AUDIOFOCUS_GAIN) :

                    mPlayer.start();
                break;
                default: break;
            }
         }
    };

    public VoiceItemView(Context context, AttributeSet attrs, int defStyle){
        super(context, attrs, defStyle);
        init();
    }

    public VoiceItemView(Context context, AttributeSet attrs) {
        super(context, attrs);
        init();
    }

    public VoiceItemView(Context context) {
        super(context);
    }

    @Override

        super.bind(item);
        audioControls.setImageResource(R.drawable.ic_play_icon);

    }

    @Override

    public void init(){
        super.init();

        LayoutInflater inflater = (LayoutInflater) getContext().getSystemService(Context.LAYOUT_INFLATER_SERVICE); 
        view = (View) inflater.inflate(R.layout.talk_voice, null);

        link = new TextView(getContext());
        link.setVisibility(GONE);

        audioSeekbar = new SeekBar(getContext());
        audioControls = new ImageButton(getContext());  

        android.view.ViewGroup.LayoutParams params = new LayoutParams(370, android.view.ViewGroup.LayoutParams.WRAP_CONTENT);
        audioSeekbar.setProgressDrawable(CustomSeekBar.setProgress(12, 8, getResources().getColor(R.color.blue_soft), Color.WHITE)); 
        audioSeekbar.setThumb(CustomSeekBar.setThumb(getResources().getColor(R.color.blue_soft), 40));
        audioSeekbar.setLayoutParams(params);
        mVoiceRecord = new VoiceRecord();
        mVoiceRecord.setContext(getContext());


        audioControls.setOnClickListener(new OnClickListener() {

            @Override
            public void onClick(View v) {

                AudioManager am = (AudioManager)getContext().getSystemService(Context.AUDIO_SERVICE);
                final int result = am.requestAudioFocus(focusChangeListener,    AudioManager.STREAM_MUSIC, AudioManager.AUDIOFOCUS_GAIN);

                if(mPlayer == null){

                    mPlayer = new MediaPlayer();
                    mHandler = new Handler();
                    mPlayer.setAudioStreamType(AudioManager.STREAM_MUSIC);
                    try {

                        mPlayer.setDataSource(link.getText().toString());
                        mPlayer.prepare();
                    } catch (IllegalArgumentException e) {

                    if (result == AudioManager.AUDIOFOCUS_REQUEST_GRANTED) {
                        mPlayer.start();
                        mPlayer.seekTo(audioSeekbar.getProgress());
                    }
                    final int duration = mPlayer.getDuration();
                    audioSeekbar.setMax(duration);

                    final int amoungToupdate = duration/100;

                    TimerTask task = new TimerTask() {
                        @Override
                        public void run() {
                            talkActivity.runOnUiThread(new Runnable() {
                                @Override
                                public void run() {

                                    if(mPlayer != null){
                                        int mCurrentPosition = mPlayer.getCurrentPosition();

                                        audioSeekbar.setProgress(mCurrentPosition);
                                    }
                                    mHandler.postDelayed(this, 1000);
                                }
                            });
                        }
                    };

                    new Timer().schedule(task, amoungToupdate);

                }
            }
        });


        setViewToContainer(audioSeekbar);
        setViewToContainer(audioControls);
    }

}

和bellow源是由父类MessageBaseItemView

abstract public class MessageBaseItemView<T> extends LinearLayout implements ICustomModel<T>{

    private TextView timeStamp;
    private ImageView avatar;
    private RelativeLayout container;
    private View viewRight, viewLeft;
    LayoutInflater inflater = (LayoutInflater) getContext().getSystemService(Context.LAYOUT_INFLATER_SERVICE); 

    final float scale = getResources().getDisplayMetrics().density;

    public MessageBaseItemView(Context context, AttributeSet attrs, int defStyle){
        super(context, attrs, defStyle);
        init();
    }

    public MessageBaseItemView(Context context, AttributeSet attrs) {
        super(context, attrs);
        init();
    }

    public MessageBaseItemView(Context context) {
        super(context);
        init();
    }


    public void setViewToContainer(List<View> listView){
        for (View view : listView) {
            container.addView(view);
        }
    }

    public void setViewToContainer(View view){
        container.addView(view);
    }

    public RelativeLayout getContainer(){
        return this.container;
    }

    @Override
    public void init(){

        inflate(getContext(), R.layout.custom_talk_list_bubble_left, this);

        viewRight = inflater.inflate(R.layout.custom_talk_list_bubble_right, null);
        viewLeft = inflater.inflate(R.layout.custom_talk_list_bubble_left, null);

        timeStamp = (TextView) findViewById(R.id.timeStamp);
        avatar = (ImageView) findViewById(R.id.avatar);
        container = (RelativeLayout) findViewById(R.id.container);
    }
}

我在适配器中使用我的VoiceItemView，我在listFragment中使用此适配器，如bellow

public class ProfileFragment extends ListFragment {

    View view;

    @Override
    public View onCreateView(LayoutInflater inflater, ViewGroup viewGroup, Bundle bundleSavedInstance){

        view = inflater.inflate(R.layout.fragment_profile_profile, viewGroup, false);

        return view;
    }

    @Override
    public void onActivityCreated(Bundle savedInstanceState) {
        super.onActivityCreated(savedInstanceState);

DynamicMessageAdapter adapter = new DynamicMessageAdapter(getActivity());


        List<VoiceItemModel> listVoice = new ArrayList<VoiceItemModel>();

        listVoice.add(new VoiceItemModel(2, "18:00", "/storage/emulated/0/Flirt/Media/Talk/Voices Mates/2015-05-27/case.aac"));
        listVoice.add(new VoiceItemModel(2, "12:09 PM", "/storage/emulated/0/Flirt/Media/Talk/Voices Mates/2015-05-27/destin.aac"));
        listVoice.add(new VoiceItemModel(4, "18:00", "/storage/emulated/0/Flirt/Media/Talk/Voices Mates/2015-05-27/boo.aac"));


        adapter.bindVoice(listVoice);

        setListAdapter(adapter);
    }

}

Android mediaPlayer Seekbar在listview的其他项目上的进度
