Android 页面跳转最简便的方法！

第一步：

    /**
     * 获取所有的Activtiy
     * 
     * @return
     */
    public static SparseArray<String> getCompanyPackageName() {
        String packbackName = "com.tiancheng.business.activity.";
        SparseArray<String> array = new SparseArray<String>();
        array.put(2, packbackName + "NoticeActivity");
        array.put(3, packbackName + "ManagerInfoFriendActivity");
        array.put(6, packbackName + "CompanyTogetherActivity");
        array.put(11, packbackName + "ServiceNeedApplyActivity");
        array.put(12, packbackName + "ServiceProgressSearchActivity");
        array.put(13, packbackName + "ServiceResultScoreActivity");
        array.put(14, packbackName + "ServiceProjectSearchActivity");
        array.put(32, packbackName + "ServiceProjectGroupSearchActivity");
        array.put(38, packbackName + "ComplaintListActivity");
        array.put(39, packbackName + "PublishMessageActivity");
        array.put(40, packbackName + "MyMessageActivity");
        return array;
    }

第二步：

/**
     * 设置权限
     */
    private void setCompanyAuthority(int position) {
        SparseArray<String> array = Utils.getCompanyPackageName();
        for (int i = 0; i < array.size(); i++) {
            if (position == array.keyAt(i)) {
                Intent intent = null;
                try {
                    intent = new Intent(this, Class.forName(array.valueAt(i)
                            .toString()));
                    intent.putExtra("Flag", 0);
                    intent.putExtra("ID", 0);
                    intent.putExtra("FWXMID", 0);
                } catch (ClassNotFoundException e) {
                    e.printStackTrace();
                }
                startActivity(intent);
            }
        }
    }

到此为止.....
