Android鍵盤返回鍵報錯java.lang.IllegalStateException: focus search returned a view that wasn't ab

點擊鍵盤的回車鍵會通過EditableInputConnection來執行onEditorAction方法，異常的原因是查詢上一個或下一個view的焦點的時候失敗了 拋出了異常，這兩處拋出異常的代碼上方有個return，如果能保證
ict.onEditorActionListener.onEditorAction(this, actionCode, null)永遠爲true那麼異常代碼就永遠不會執行
即設置EditText的onEditorActionListener()

 //點擊鍵盤返回不報異常
        et_search.setOnEditorActionListener(new TextView.OnEditorActionListener() {
            @Override
            public boolean onEditorAction(TextView v, int actionId, KeyEvent event) {
                //可以根據需求獲取下一個焦點還是上一個
                View nextView = v.focusSearch(View.FOCUS_DOWN);
                if (nextView != null) {
                    nextView.requestFocus(View.FOCUS_DOWN);
                }
                //這裏一定要返回true
                return true;
            }
        });
