8.TextView文字不居中 文本邊距取消留白
添加<TextView>標簽屬性android:includeFontPadding="false"設(shè)置TextView文本邊距取消留白
9.xml 去除<Button>自帶樣式
style="?android:attr/borderlessButtonStyle"
10.xml——虛線畫法
<?xml version="1.0" encoding="utf-8"?>
<shape xmlns:android="http://schemas.android.com/apk/res/android"
android:shape="line">
<stroke
android:width="2dp"
android:color="#E6F0F8"
android:dashWidth="3dp"
android:dashGap="3dp" />
<size android:height="2dp" />
</shape>
android:width 虛線的寬度
android:dashWidth 虛線一個點點的長度（我也不知道咋描述了）
android:dashGap 虛線點點之間的距離（就這么描述吧）
最后最重要的一步，要在使用改虛線資源的布局里寫一句
android:layerType="software"
要不顯示出來的效果是一條實心的直線
11.listview點擊item字體顏色selector
<?xml version="1.0" encoding="utf-8"?>
<selector xmlns:android="http://schemas.android.com/apk/res/android">
<item android:state_focused="true" android:color="@color/colorWhiteFour" /> <!-- focused -->
<item android:state_pressed="true" android:color="@color/colorOrangeTow" /> <!-- pressed -->
<item android:state_selected="true" android:color="@color/colorOrangeTow" /> <!-- pressed -->
<item android:color="@color/colorWhiteFour" /> <!-- default -->
</selector>
