Android 自定义按钮

1.编写一个按键up的shape和一个按键down时的shape。（区别在于实体部分颜色不同）

1）Up的shape

<?xml version="1.0"encoding="utf-8"?>
<shape xmlns:android="http://schemas.android.com/apk/res/android">

    <solid android:color="#00000000"/><!--实体透明-->

    <padding
            android:bottom="10dp"
            android:top="10dp"
            android:left="10dp"
            android:right="10dp"/>

    <corners
            android:bottomLeftRadius="10dp"
            android:bottomRightRadius="10dp"
            android:topLeftRadius="10dp"
            android:topRightRadius="10dp"/>


    <stroke
            android:width="@dimen/button_width"
            android:color="@color/button_font_blue"/>
</shape>

2）down时的shape

<?xml version="1.0" encoding="utf-8"?>
<shape xmlns:android="http://schemas.android.com/apk/res/android" >

    <solid android:color="#5dcfe8" />

    <padding
        android:bottom="10dp"
        android:top="10dp"
        android:left="10dp"
        android:right="10dp"/>

    <corners
        android:bottomLeftRadius="10dp"
        android:bottomRightRadius="10dp"
        android:topLeftRadius="10dp"
        android:topRightRadius="10dp" />


    <stroke
        android:width="@dimen/button_width"
        android:color="@color/button_font_blue" />
</shape>

2.编写selector,transparent_button

<?xml version="1.0" encoding="utf-8"?>
<selector xmlns:android="http://schemas.android.com/apk/res/android">
    <!--enable一定要写在前面-->
    <item android:state_enabled="false" android:drawable="@drawable/transparent_button_down"/>
    <item android:state_pressed="false" android:drawable="@drawable/transparent_button_up"/>
    <item android:state_pressed="true" android:drawable="@drawable/transparent_button_down"/>
</selector>

3.在布局里面添加button,background引用transparent_button

<Button
    android:id="@+id/btRight"
    android:layout_width="@dimen/udp_button_height"
    android:layout_height="@dimen/udp_button_height"
    android:layout_alignBottom="@+id/btOk"
    android:layout_marginLeft="@dimen/udp_button_spacing"
    android:layout_toRightOf="@+id/btOk"
    android:textColor="@color/button_font_blue"
    android:text="→"
    android:background="@drawable/transparent_button"/>
