EditText失去焦點時隱藏軟鍵盤

Fragment里寫在Activity中，好象這個最管用：

 //隱藏軟鍵盤
    //在activity里面重寫  dispatchTouchEvent
    @Override
    public boolean dispatchTouchEvent(MotionEvent ev) {
        if (ev.getAction() == MotionEvent.ACTION_DOWN) {
            View v = getCurrentFocus();
            if (isShouldHideInput(v, ev)) {
                InputMethodManager imm = (InputMethodManager) getSystemService(Context.INPUT_METHOD_SERVICE);
                if (imm != null) {
                    imm.hideSoftInputFromWindow(v.getWindowToken(), 0);
                }
            }
            return super.dispatchTouchEvent(ev);
        }
// 必不可少，否則所有的組件都不會有TouchEvent了
        if (getWindow().superDispatchTouchEvent(ev)) {
            return true;
        }
        return onTouchEvent(ev);
    }


    /**
     * 是否隱藏鍵盤
     */
    public static boolean isShouldHideInput(View v, MotionEvent event) {
        if ((v instanceof EditText)) {
            int[] leftTop = {0, 0};
//獲取輸入框當前的location位置
            v.getLocationInWindow(leftTop);
            int left = leftTop[0];
            int top = leftTop[1];
            int bottom = top + v.getHeight();
            int right = left + v.getWidth();
            // 點擊的是輸入框區域，保留點擊EditText的事件
            return !(event.getX() > left) || !(event.getX() < right)
                    || !(event.getY() > top) || !(event.getY() < bottom);
        }
        return false;
    }

 

 

重寫方法：

 @Override
    public boolean onTouchEvent(MotionEvent event) {
        InputMethodManager imm = (InputMethodManager) getSystemService(Context.INPUT_METHOD_SERVICE);
        imm.hideSoftInputFromWindow(editText_phone.getWindowToken(), 0);
        imm.hideSoftInputFromWindow(editText_phone.getWindowToken(), 0);
        return super.onTouchEvent(event);
    }

　這個更直接，好理解（rootLayout為根布局）：

  /*點擊鍵盤外隱藏軟鍵盤*/
        binding.rootLayout.setOnTouchListener(new View.OnTouchListener() {
            @SuppressLint("ClickableViewAccessibility")
            @Override
            public boolean onTouch(View v, MotionEvent event) {

                if(null!= requireActivity().getCurrentFocus()){

                    InputMethodManager manager= (InputMethodManager) requireActivity().getSystemService(Context.INPUT_METHOD_SERVICE);

                    if(manager!=null){
                        return manager.hideSoftInputFromWindow(requireActivity().getCurrentFocus().getWindowToken(),0);
                    }
                }
                return false;
            }
        });
