#024: 播放器播放和暂停功能实现
#首页
##1. 播放 ###1.1 在从上一个专辑页面切换到播放器页面时自动播放 TrackPlayerActivity.java:
protected void onCreate(Bundle savedInstanceState) {
startPlay();
}
private void startPlay() {
if (playerPresenter != null) {
playerPresenter.play();
}
}
PlayerPresenter.java:
public void play() {
if(isPlayListSet){
xmPlayerManager.play();
}
}
###1.2 播放图标设置点击事件 点击播放按钮时，如果目前没有播放就开始播放，当收到SDK的onPlayStart回调方法时，切换播放按钮成暂停按钮，如果目前当前正在播放，就停止播放，当收到SDK的onPlayPause回调方法时，切换暂停按钮成播放按钮
TrackPlayerActivity.java:
private void initEvent() {
if (playImageView != null) {
playImageView.setOnClickListener(this);
}
}
public void onClick(View view) {
if(view == playImageView){
if(playerPresenter.isPlaying()) {
pause();
return;
}else{
startPlay();
}
}
}
@Override
public void onPlayStart() {
if (playImageView!=null) {
playImageView.setImageResource(R.mipmap.stop);
}
}
@Override
public void onPlayPause() {
if (playImageView!=null) {
playImageView.setImageResource(R.mipmap.play);
}
}
PlayerPresenter.java:
public void play() {
if(isPlayListSet){
xmPlayerManager.play();
}
}
@Override
public void pause() {
xmPlayerManager.pause();
}
@Override
public void onPlayStart() {
for (IPlayerCallback playerCallback : playerCallbacks) {
playerCallback.onPlayStart();
}
}
@Override
public void onPlayPause() {
for (IPlayerCallback playerCallback : playerCallbacks) {
playerCallback.onPlayPause();
}
}
##2. SDK导入 TingPhoneOpenSDK_XXX.jar拷贝到libs目录下
##3.声明权限 在项目Manifest文件中声明以下权限（监听电话状态，当有来电或去电时，自动暂停，当电话结束后，自动恢复播放）
<uses-permission android:name="android.permission.READ_PHONE_STATE" />
<uses-permission android:name="android.permission.PROCESS_OUTGOING_CALLS" />
##4.注册播放器服务 在App的AndroidManifest.xml文件中注册播放器服务
<application
...
<service android:name="com.ximalaya.ting.android.opensdk.player.service.XmPlayerService"
android:process=":player"/>
</application>
##5. 初始化播放器 BaseApplication.java:
XmPlayerManager.getInstance(this).init();
##6. 播放器页面创建逻辑处理类 创建一个播放逻辑处理类和喜马拉雅播放器进行交互 PlayerPresenter.java
public class PlayerPresenter implements IPlayerPresenter {
private final String TAG = "PlayerPresenter";
private static PlayerPresenter sInstance = null;
private XmPlayerManager xmPlayerManager;
private boolean isPlayListSet = false;
private PlayerPresenter(){
xmPlayerManager = XmPlayerManager.getInstance(BaseApplication.getAppContext());
}
public static PlayerPresenter getsInstance() {
if(null == sInstance){
synchronized (PlayerPresenter.class){}
if(null == sInstance){
sInstance = new PlayerPresenter();
}
}
return sInstance;
}
public void setPlayList(List<Track> tracks, int currentIndex){
if (xmPlayerManager != null) {
xmPlayerManager.setPlayList(tracks,currentIndex);
isPlayListSet = true;
}else {
LogUtil.e(TAG, "xmPlayerManager is null");
}
}
@Override
public void play() {
if(isPlayListSet){
xmPlayerManager.play();
}
}
@Override
public void pause() {
}
@Override
public void stop() {
}
@Override
public void playPre() {
}
@Override
public void playNext() {
}
@Override
public void setPlayMode(XmPlayListControl.PlayMode playMode) {
}
@Override
public void getPlayList() {
}
@Override
public void playByIndex(int index) {
}
@Override
public void seekTo(int progress) {
}
@Override
public void registerCallback(IPlayerCallback iPlayerCallback) {
}
@Override
public void unRegisterCallback(IPlayerCallback iPlayerCallback) {
}
}
##7. 专辑页面点击时传递专辑列表到播放器 AlbumDetailActivity.java:
@Override
public void onItemClick(List<Track> tracks, int position) {
PlayerPresenter.getsInstance().setPlayList(tracks, position);
Intent intent = new Intent(this, TrackPlayerActivity.class);
startActivity(intent);
}
