我正在研究音乐播放器 - 窗口窗口小部件。.它只需要播放1首歌曲(最好是Mediaplayer Class)。但是我不确定如何实施它。我对Android的开发有所缺乏经验,因此提到了这一点。
到目前为止,我的课程扩展了 AppWidgetProvider
, ,我想让本班处理音乐播放部分不是一个好主意,而是一个好主意 Service
. 。如果是这样,怎么样?
此外,我有3个按钮:播放,暂停和停止,我可以区分哪个按钮 onReceive(...)
.
提前致谢!
这是班级。
public class MusicManager extends AppWidgetProvider {
private final String ACTION_WIDGET_PLAY = "PlaySong";
private final String ACTION_WIDGET_PAUSE = "PauseSong";
private final String ACTION_WIDGET_STOP = "StopSong";
private final int INTENT_FLAGS = 0;
private final int REQUEST_CODE = 0;
@Override
public void onUpdate(Context context, AppWidgetManager appWidgetManager,
int[] appWidgetIds) {
RemoteViews controlButtons = new RemoteViews(context.getPackageName(),
R.layout.main);
Intent playIntent = new Intent(context, MusicService.class);
Intent pauseIntent = new Intent(context, MusicService.class);
Intent stopIntent = new Intent(context, MusicService.class);
PendingIntent playPendingIntent = PendingIntent.getService(
context, REQUEST_CODE, playIntent, INTENT_FLAGS);
PendingIntent pausePendingIntent = PendingIntent.getService(
context, REQUEST_CODE, pauseIntent, INTENT_FLAGS);
PendingIntent stopPendingIntent = PendingIntent.getService(
context, REQUEST_CODE, stopIntent, INTENT_FLAGS);
controlButtons.setOnClickPendingIntent(
R.id.btnPlay, playPendingIntent);
controlButtons.setOnClickPendingIntent(
R.id.btnPause, pausePendingIntent);
controlButtons.setOnClickPendingIntent(
R.id.btnStop, stopPendingIntent);
appWidgetManager.updateAppWidget(appWidgetIds, controlButtons);
}
}
解决方案
添加 <service android:name=".MusicService" android:enabled="true" />
表现出来!
其他提示
在里面 onUpdate(...)
您的方法 AppWidgetProvider
, ,使用类似的内容来启动服务(此示例将服务与按钮单击事件相关联):
Intent intent = new Intent(context, MusicService.class);
PendingIntent pendingIntent = PendingIntent.getService(context, 0, intent, 0);
// Get the layout for the App Widget and attach an on-click listener to the button
RemoteViews views = new RemoteViews(context.getPackageName(), R.layout.appwidget_provider_layout);
views.setOnClickPendingIntent(R.id.button, pendingIntent);
