Answer 1

JOptionPane.showMessageDialog 莫非是这种弹出框？我也才刚学的，不知道对不对，呵呵

Answer 2

要 android 中 自动弹出的 

Answer 3

if (mBluetoothAdapter.isEnabled()){
                    new Thread(new Runnable(){
                        public void run(){
                            showToast();
                        }
                    }).start();                    Handler handler = new Handler();
                    public void showToast(){
                        handler.post(new Runnable(){
                            @Override
                            public void run(){
                                Toast.makeText(PhoneWindowManager.this, "closing bluetooth", Toast.LENGTH_SHORT).show();
                                System.out.println("closing bluetooth");
                            }
                        });
                    }
                    mBluetoothAdapter.disable();
}
这样不行啊 public void showToast() 非法的表达式开始
