#首页

点击播放器节目列表弹出窗口上切换模式图标能够改变播放模式，并同时修改播放器节目相应的播放模式图标

##1. 创建一个播放模式监听接口和注册接口

PlayListPopupWindow.java:

public interface PlayModeClickListener{
    void onClick();
}

public void setPlayModeClickListener(PlayModeClickListener playModeClickListener){
        this.playModeClickListener = playModeClickListener;
    }

##2. 播放器类注册播放器监听接口

TrackPlayerActivity.java:

playListPopupWindow.setPlayModeClickListener(new PlayListPopupWindow.PlayModeClickListener() {
    @Override
    public void onClick() {
        switchPlayMode();
    }
});

##3. 播放器列表弹出窗口播放模式图标添加点击事件，并回调注册方法

PlayListPopupWindow.java:

playModeIV.setOnClickListener(new View.OnClickListener() {
    @Override
    public void onClick(View view) {
        playModeClickListener.onClick();
    }
});

##4. 修改播放器列表弹出窗口播放模式图标和文字

TrackPlayerActivity.java:

public void onPlayModeChanged(XmPlayListControl.PlayMode playMode) {
    currentPlayMode = playMode;

    if (playListPopupWindow != null) {
        playListPopupWindow.updatePlayModeImage(playMode);
    }
    updatePlayModeImage();
}

PlayListPopupWindow.java:

public void updatePlayModeImage(XmPlayListControl.PlayMode playMode) {
    int resId = R.drawable.selector_player_mode_list;
    int tvResId = R.string.play_mode_order;

    switch (playMode){
        case PLAY_MODEL_LIST_LOOP:
            resId = R.drawable.selector_player_mode_list_loop;
            tvResId = R.string.play_mode_order_loop;
            break;
        case PLAY_MODEL_LIST:
            resId = R.drawable.selector_player_mode_list;
            tvResId = R.string.play_mode_order;
            break;
        case PLAY_MODEL_RANDOM:
            resId = R.drawable.selector_player_mode_random;
            tvResId = R.string.play_mode_random;
            break;
        case PLAY_MODEL_SINGLE_LOOP:
            resId = R.drawable.selector_player_mode_loop_one;
            tvResId = R.string.play_mode_single_loop;
            break;
    }
    playModeIV.setImageResource(resId);
    playModeTitle.setText(tvResId);
}
