Android如何画矩形图，结合selecter

在drawable里面创建button_boost.xml

xmlns:android="http://schemas.android.com/apk/res/android"

android:shape="rectangle">

android:color="@color/blue_boost"

android:width="1dp"/>

android:radius="20dp" />

button_boost_press.xml

xmlns:android="http://schemas.android.com/apk/res/android"

android:shape="rectangle">

android:color="@color/blue_boost"  //外圈为blue_boost

android:width="1dp"/>                                //空心外圈宽度为1dp

android:color="@color/blue_boost_press" /> //矩形框里实心颜色为blue_boost_press

android:radius="20dp" /> //矩形边角弧度半径

selecter器

在drawable中建立button_selector.xml

xmlns:android="http://schemas.android.com/apk/res/android">

android:drawable="@drawable/button_boost"android:state_pressed="false" /> //不点击时的显示图片

android:drawable="@drawable/button_boost_press"android:state_pressed="true" /> //点击时的显示图片

使用

android:id="@+id/clean"

style="?android:attr/borderlessButtonStyle"

android:layout_width="wrap_content"

android:layout_height="wrap_content"

android:layout_gravity="center"

android:background="@drawable/button_selector"

android:ellipsize="end"

android:gravity="center"

android:paddingEnd="25dp"

android:paddingStart="25dp"

android:singleLine="true"

android:textColor="#444444"

android:textAllCaps="false"

android:textSize="@dimen/main_tv_title_text_size" />
