我使用下面的代碼:public class MyCount extends CountDownTimer
{
public MyCount(long millisInFuture, long countDownInterval)
{
super(millisInFuture, countDownInterval);
}
@Override
public void onFinish()
{
displayAlertForRestart();
}
@Override
public void onTick(long millisUntilFinished)
{
counter.setText("Time Left: " + millisUntilFinished/1000 + " sec");
}
}
public void displayAlertForRestart()
{
AlertDialog.Builder builder = new AlertDialog.Builder(this);
builder.setCancelable(true);
builder.setMessage("Do you want to Restart?");
builder.setTitle("Game Over");
builder.setInverseBackgroundForced(true);
builder.setPositiveButton("Yes", new DialogInterface.OnClickListener()
{
public void onClick(DialogInterface dialog, int which) {
Intent myIntent = new Intent(context,Level.class);
startActivity(myIntent);
dialog.dismiss();
finish();
}
});
builder.setNegativeButton("No", new DialogInterface.OnClickListener() {
public void onClick(DialogInterface dialog, int which) {
dialog.dismiss();
finish();
}
});
AlertDialog alert = builder.create();
alert.show();
}alert.show();處的 LogCat error：36: E/AndroidRuntime(9829): android.view.WindowManager$BadTokenException: Unable to add window -- token android.
os.BinderProxy@43cf1e38 is not valid; is your activity running?

AlertDialog.Builder builder = new AlertDialog.Builder(this);
