環信聊天消息提示音的實現 仿微信新消息提示音設置。

思路：用RingtoneManager查詢出title，Ringtone，uri信息，title用來展示，Ringtone用來播放，uri設置提示音時保存到本地，消息到來時，從本地獲取存儲的Uri，然后根據uri獲取Ringtone對象，播放提示音。

效果圖：

布局文件用ListView

實體類，用來存儲提示音信息：

/** *@author 強 *@time 2017-03-01 10:49 * @類描述：用於存儲ringtone對象和uri * @變更記錄: */

public class RingtoneBean {

private String title;//提示音標題

private String uriPath;//提示音Uri路徑

private Ringtone ringtone;

public RingtoneBean(String title, String uriPath, Ringtone ringtone) {

this.title = title;

this.uriPath = uriPath;

this.ringtone = ringtone;

}

public String getTitle() {

return title;

}

public void setTitle(String title) {

this.title = title;

}

public String getUriPath() {

return uriPath;

}

public void setUriPath(String uriPath) {

this.uriPath = uriPath;

}

public Ringtone getRingtone() {

return ringtone;

}

public void setRingtone(Ringtone ringtone) {

this.ringtone = ringtone;

}

}

工具類核心方法，獲取提示音列表

public List getRingtoneBeanList(int type) { List resArr = new ArrayList<>(); RingtoneManager manager = new RingtoneManager(mContext); manager.setType(type); Cursor cursor = manager.getCursor(); RingtoneBean bean = null; if (cursor.moveToFirst()) { do { //獲取uri廢了一番功夫，api用的23，好多方法沒有了，這句還是查看RingtoneManager源碼找到的。以后還是要多看系統源碼。 Uri uri = ContentUris.withAppendedId(Uri.parse(cursor.getString(RingtoneManager.URI_COLUMN_INDEX)), cursor .getLong(RingtoneManager.ID_COLUMN_INDEX)); Log.e("uri",uri.toString()); String title = cursor.getString(RingtoneManager.TITLE_COLUMN_INDEX); Ringtone ringtone = getRingtoneByUriPath(type, uri.toString()); bean = new RingtoneBean(title,uri.toString(),ringtone); resArr.add(bean); } while (cursor.moveToNext());

}

return resArr;

}

有了數據，接下來就是適配adapter了

/** *@author 丁建強 *@time 2017-03-01 13:00 * @類描述：提示音適配器 * @變更記錄: */

public class SoundAdapter extends BaseAdapter {

private Context mContext;

private int index;//當前選中的index

private List list;

public SoundAdapter(Context mContext, List list) {

this.mContext = mContext;

this.list = list;

}

public void setCurrentIndex(int index) {

this.index = index;

notifyDataSetChanged();

}

@Override

public int getCount() {

return list == null ? 0 : list.size();

}

@Override

public Object getItem(int i) {

return list.get(i);

}

@Override

public long getItemId(int i) {

return i;

}

@Override

public View getView(int i, View view, ViewGroup viewGroup) {

ViewHolder holder = null;

if (view == null) {

view = View.inflate(mContext, R.layout.activity_sound_item, null);

holder = new ViewHolder(view);

view.setTag(holder);

} else {

holder = (ViewHolder) view.getTag();

}

holder.tvName.setText(list.get(i).getTitle());

if (index == i) {

holder.iv_sound.setImageResource(R.mipmap.checked);

} else {

holder.iv_sound.setImageResource(R.mipmap.unckecked);

}

return view;

}

static class ViewHolder {

public TextView tvName;

public ImageView iv_sound;

public ViewHolder(View view) {

tvName = (TextView) view.findViewById(R.id.tv_sound_name);

iv_sound = (ImageView) view.findViewById(R.id.iv_sound);

}

}

}

listview點擊時，選中當前項，並播放選中的提示音

listView.setOnItemClickListener(new AdapterView.OnItemClickListener() {

@Override

public void onItemClick(AdapterView> adapterView, View view, int i, long l) {

adapter.setCurrentIndex(i);//選中當前項

//停止播放之前的

if (tempRingtone != null && tempRingtone.isPlaying()) {

tempRingtone.stop();

}

tempRingtone = ringtoneBeanList.get(i).getRingtone();

tempRingtone.play();

saveIndex = i;

}

});

點保存按鈕時，把選擇的提示音的uri保存到本地

tvSave.setOnClickListener(new View.OnClickListener() {

@Override

public void onClick(View view) {

String uriPath = ringtoneBeanList.get(saveIndex).getUriPath();

String title = ringtoneBeanList.get(saveIndex).getTitle();

SharedPreferences.Editor editor = preferences.edit();

if (type == 0) {

editor.putString("private_soundTitle", title);

editor.putString("private_soundUriPath", uriPath);

} else {

editor.putString("group_soundTitle", title);

editor.putString("group_soundUriPath", uriPath);

}

editor.commit();

finish();

}

});

這個功能就差不多了，等環信聊天消息到來時調用環信的EaseNotifier，修改此方法，環信默認的提示音是系統的提示音，可以更改去播放自己設置保存到本地的提示音，自定義提示音就實現了。
