學習Android從0開始之基礎篇（4）-TextView與EditText · 學習Android從0開始

##TextView與EditText詳解 TextView? 顧名思義：就是在界面上呈現文本信息，主要用于顯示，沒有特殊的事件響應。然而EditText與TexView非常相似，EditText就是多了一個可以讓用戶輸入內容的編輯框功能。???? 大家可以把EditText看作是編輯內容的那個框，TextView是用于顯示文本內容的框。? 其實就是這么簡單。然而EditText是TextView的子類。接下來就是TextView和EditText的全部XML屬性如下。不過在此之前，要先解釋一個屬性margin和padding ? margin和padding如下圖所示： ![](https://box.kancloud.cn/2016-04-26_571f42c854c94.jpg) margin是子容器相距父容器邊框的距離，而padding是子容器中的內容距離子容器邊框的距離。那么margin_left和margin_right、padding_left和padding_right之類的屬性就很好理解了。比如margin_left就是子容器距離父容器左邊這一邊的偏移距離，其他什么right、top、bottom都是這個意思。 1.? TextView和EditText的xml屬性。好了理解了這兩個屬性之后，我們來看看官網對TextView的屬性介紹：??經常用的用紅色顯示 <table class="jd-sumtable " id="lattrs"><tbody><tr><th colspan="12">XML Attributes</th></tr><tr><td><nobr><em>Attribute

![](https://box.kancloud.cn/2016-04-26_571f42c88d34a.jpg) 2.EditText。的重要方法如下；通過官網，我們可以看到，官網給出了EditText的一些方法。如下： ![](https://box.kancloud.cn/2016-04-26_571f42c8a653e.jpg) 其中最重要的就是? getText() 這個方法。通過這個方法，可以獲得EditText中的文本信息。這樣就能提取信息，一般都是在登陸界面和評論的地方，通過getText（）方法來獲取用戶輸入的內容。然后，把這些內容發送到服務器，然后提交服務器成功后。然后就把最新的評論數據從網絡中返回到手機上。然后手機上面呈現出最新的評論結果。好了TetxtView和Edittext的方法和xml屬性就介紹完了，然后如果不記得textview和EditText的xml屬性是什么屬性的話就查看上面的xml屬性表。
