可能是一个愚蠢的问题，但真的在谷歌寻找2小时。实际上我的应用程序在前棒棒糖中崩溃但在其他版本中运行良好。以下是崩溃报告。

我使用自定义背景作为按钮，如下所示：

<Button
    android:id="@+id/btnCompleted"
    android:layout_weight="1"
    android:layout_gravity="left"
    android:text="Completed"
    android:textColor="@android:color/white"
    android:background="@drawable/custom_button_selected"
    android:layout_width="wrap_content"
    android:layout_height="wrap_content" />

custom_button_selected.xml

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

            <stroke
                android:width="2dp"
                android:color="@color/transparent_color8" />

                android:top="10dp"

        </shape>
    </item>
    <item android:state_focused="true" >
        <shape>
            <gradient

                android:startColor="?attr/icon_color"

            <stroke
                android:width="2dp"

                android:right="10dp"
                android:bottom="10dp" />
        </shape>
    </item>

    <item>
        <shape>
            <gradient
                android:startColor="?attr/icon_color"
                android:endColor="?attr/icon_color"

            <padding

        </shape>
    </item>
</selector>

Answer 1

StateListDrawable可用于更改按钮的状态（按下，聚焦......），如果您打算使用custom_button_selected.xml作为背景来改变按钮的状态，那么您将失踪drawable内部selector内容item内<item android:state_pressed="true" android:drawable="@color/transparent_color8"> .... </item>。像这样：

Select * from ndc group by order_id; - 或者你想用的任何颜色

Answer 2

android {defaultConfig {vectorDrawables.useSupportLibrary = true}}
