具有以下代码来运行 mp3 播客
public void playPodcast( final Uri data){
new Thread (new Runnable(){
public void run() {
if(!mediaPlayer.isPlaying()){
try {
mediaPlayer.setDataSource(getApplicationContext(), data);
} catch (IllegalArgumentException e) {
// TODO Auto-generated catch block
e.printStackTrace();
} catch (SecurityException e) {
// TODO Auto-generated catch block
e.printStackTrace();
} catch (IllegalStateException e) {
// TODO Auto-generated catch block
e.printStackTrace();
} catch (IOException e) {
// TODO Auto-generated catch block
e.printStackTrace();
}
try {
mediaPlayer.prepare();
} catch (IllegalStateException e) {
// TODO Auto-generated catch block
e.printStackTrace();
} catch (IOException e) {
// TODO Auto-generated catch block
e.printStackTrace();
}
mediaFileLengthInMilliseconds = mediaPlayer.getDuration();
duracaoPodcast = mediaPlayer.getDuration();
mediaPlayer.start();
if(!(controlTimer >= 1)){
timer();
controlTimer++;
}
primarySeekBarProgressUpdater();
}
}
}).start();
}
并关闭用户意图有:
voltar.setOnClickListener(new View.OnClickListener() {
public void onClick(View v) {
finish();
mediaPlayer.stop();
}
});
当用户关闭所有带有android的返回按钮手机的意图时会出现问题,因为它没有:
finish();
mediaPlayer.stop();
只做:
finish();
所以音频仍在播放,即使我回到那个意图暂停:
stop.setOnClickListener(new View.OnClickListener() {
public void onClick(View v) {
if(mediaPlayer.isPlaying()){
mediaPlayer.stop();
frame.setVisibility(View.INVISIBLE);
}
}
});
按钮不起作用,如果我按下播放,他会在空播放的顶部开始一个新的音频,
知道如何解决吗?
