我正在构建仅用于自用的应用程序-根据日出和日落设置了不同的警报（穆斯林纳马兹时间）
对于警报，我使用了计时器，该计时器不断检查设备时间和警报时间。如果两者相同，警报会播放。
但是在点击通知后我无法停止闹钟。
onResume我已经尝试过mediaplayer.stop()，但是它多次播放媒体。

答案 0 :(得分：1)
void playSounds( int i ){
String message = "Stop";
//1=Azzan; 0 = Alarm
if(i == 0)
{
if( mediaPlayer != null )
{
mediaPlayer.reset();
mediaPlayer.release();
}
....

继续您的东西
您可以使用
mediaPlayer.reset();
