如何實現點擊屏幕其他地方讓edittext失去焦點

方法就是：讓EditText所在的layout獲得焦點。
給layout注冊OnTouchListener監聽器
直接使用  .requestFocus()   無法獲取焦點，焦點依然在EditTtext上
先調用下面這兩個方法：
.setFocusable(true);
.setFocusableInTouchMode(true);
再調用  .requestFocus() 就可獲取焦點

relative.setOnTouchListener(new OnTouchListener() {
                       
                        public boolean onTouch(View v, MotionEvent event) {
                                // TODO Auto-generated method stub
                                relative.setFocusable(true);
                                relative.setFocusableInTouchMode(true);
                                relative.requestFocus();

                                return false;
                        }
                });
