当我删除 onResume() 方法时，程序运行良好，但是当我将其留在程序中时，程序正常启动，音乐播放，但屏幕上没有显示任何内容，然后当我尝试退出时，它冻结并需要一分钟电话从被冻结中走出来。这个 onResume() 方法有什么问题？您需要查看我的所有代码吗？为什么会发生这种情况？
@Override
protected void onResume() {
// TODO Auto-generated method stub
super.onResume();
int spot = settings.getInt("point", 0);
try {
music.get(track).prepare();
} catch (IllegalStateException e) {
// TODO Auto-generated catch block
e.printStackTrace();
} catch (IOException e) {
// TODO Auto-generated catch block
e.printStackTrace();
}
music.get(track).seekTo(spot);
music.get(track).start();
}
这是 onCreate()
@Override
public void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.main);
song0 = MediaPlayer
.create(TheParty0Activity.this, R.raw.blacksunempire);
song1 = MediaPlayer.create(TheParty0Activity.this, R.raw.blueskies);
song2 = MediaPlayer.create(TheParty0Activity.this, R.raw.fuckingnoise);
music.add(song0);
music.add(song1);
music.add(song2);
music.get(track).start();
// box = (TextView) findViewById(R.id.editText1);
// play = (Button) findViewById(R.id.button0);
next = (Button) findViewById(R.id.button1);
// extra = (Button) findViewById(R.id.button2);
next.setOnClickListener(new View.OnClickListener() {
public void onClick(View v) {
// TODO Auto-generated method stub
music.get(track).stop();
track++;
if (track == 3) {
for (int i = 0; i < 3; i++) {
try {
music.get(i).prepare();
} catch (IllegalStateException e) {
// TODO Auto-generated catch block
e.printStackTrace();
} catch (IOException e) {
// TODO Auto-generated catch block
e.printStackTrace();
}
music.get(i).seekTo(0);
}
track = 0;
}
music.get(track).start();
}
});
extra.setOnClickListener(new View.OnClickListener() {
public void onClick(View v) {
// TODO Auto-generated method stub
Intent ourIntent = new Intent(TheParty0Activity.this, Sam.class);
startActivity(ourIntent);
}
});
}
