Android : how to know if MediaPlayer is paused?
提问by Regis_AG
MediaPlayer.isPlaying()does not allow to know if the MediaPlayeris stopped or paused. How to know if it is paused and not stopped?
MediaPlayer.isPlaying()不允许知道MediaPlayer是停止还是暂停。如何知道它是暂停而不是停止？
Thanks !
谢谢 ！

There is no API to check if MediaPlayeris paused or not. So please use any Boolean variable to check and toggle it when you paused using any button.
没有 API 来检查是否MediaPlayer暂停。因此，当您暂停使用 any 时，请使用任何布尔变量来检查和切换它button。
onClick(){
if(isPaused)
{
//resume media player
isPaused = false;
}else{
// pause it
isPaused = true;
}
}

As Ankit answered there is no API to check whether Media Player is paused or not ,we have to check it programmatically like this
正如 Ankit 回答的那样，没有 API 来检查媒体播放器是否已暂停，我们必须像这样以编程方式检查它
private boolean pause=true; //A Boolean variable to check your state declare it true or false here depends upon your requirement
Now you can make a method here to check that whenever you want to check player is pause
现在您可以在此处创建一个方法来检查何时要检查播放器是否暂停
public void checkplayer(MediaPlayer player){
if(isPause=true) //check your declared state if you set false or true here
Player.pause();
else if(isPause=false){
Player.play();
or
Player.stop();
}

One way to do this is to check if the media player it not playing (paused) and check if it is at a position other than the starting position (1).
执行此操作的一种方法是检查媒体播放器是否未播放（暂停）并检查它是否位于起始位置 (1) 以外的位置。
MediaPlayer mediaPlayer = new MediaPlayer();
Boolean isPaused = !mediaPlayer.isPlaying() && mediaPlayer.getCurrentPosition() > 1;

Define a booleanvariable called playedAtLeastOnce(or whatever you want) then set it to trueif your MediaPlayerobject has been played at least for one time. A good place to assign it to true is in onPrepared(MediaPlayer mp)method from MediaPlayer.OnPreparedListenerimplemented interface.
定义一个boolean名为playedAtLeastOnce（或任何你想要的）的变量，然后将它设置为true如果你的MediaPlayer对象至少播放了一次。将它分配给 true 的一个好地方是在实现接口的onPrepared(MediaPlayer mp)方法中MediaPlayer.OnPreparedListener。
Then if MediaPlayeris not playing and playedAtLeastOnceis true, you can say that MedaiPlayeris paused.
那么如果MediaPlayer不是在播放，playedAtLeastOnce是true，你可以说MedaiPlayer是暂停。
boolean playedAtLeastOnce;
@Override
public void onPrepared(MediaPlayer mp) {
mp.start();
playedAtLeastOnce = true;
}
public boolean isPaused() {
if (!mMediaPlayer.isPlaying && playedAtLeastOnce)
return true;
else
return false;
// or you can do it like this
// return !mMediaPlayer.isPlaying && playedAtLeastOnce;
}
