Question

我的主要布局看起来像这样。

<?xml version="1.0" encoding="UTF-8"?>
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
    xmlns:tools="http://schemas.android.com/tools"
    android:layout_width="match_parent"
    android:layout_height="match_parent"
    android:background="@android:color/transparent"
    android:orientation="vertical"
    android:padding="0dp"
    tools:context="com.send.apk.bluetoothappsend.MainActivity">

    <include
        android:id="@+id/tool_bar"
        layout="@layout/tool_bar" />

    <android.support.v7.widget.RecyclerView
        android:id="@+id/rv"
        android:layout_width="match_parent"
        android:layout_height="0dp"
        android:layout_weight="1"
        android:background="@drawable/background" />

    <RelativeLayout
        android:layout_width="match_parent"
        android:layout_height="@dimen/_80sdp"
        android:background="@drawable/ic_footer" />
</LinearLayout>

我使用以下载体

<vector xmlns:android="http://schemas.android.com/apk/res/android"
        android:width="1124dp"
        android:height="306dp"
         android:tint="@android:color/transparent"
        android:viewportWidth="11240.0"
        android:viewportHeight="3060.0">
    <path
        android:pathData="M179,3046c-111,-20 -146,-55 -166,-170 -17,-96 -18,-1749 -2,-1861 18,-122 69,-172 194,-194 41,-7 417,-11 1126,-11 585,0 1168,-5 1294,-10 330,-14 760,-47 905,-70 415,-63 789,-207 1132,-437 277,-184 448,-251 718,-278 183,-19 297,-19 480,0 270,27 441,94 718,279 370,247 789,400 1238,451 462,52 862,65 2088,65 713,0 1090,4 1131,11 125,22 176,72 194,194 16,112 15,1765 -2,1861 -21,117 -54,150 -171,171 -100,17 -10778,17 -10877,-1z"
        android:strokeColor="#00000000"
        android:fillColor="#090b17"/>
</vector>

但问题是，存在一些黑色背景作为图片，我需要透明背景

Answer 1

首先，如果您需要透明视图，您可能首先不应该使用矢量图像。但问题是您将填充颜色设置为#090b17，其应为#00000000。

或者，您可以将RelativeLayout的背景设置为：

android:background="@android:color/transparent"

Answer 2

试试这个

<?xml version="1.0" encoding="UTF-8"?>
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
    xmlns:tools="http://schemas.android.com/tools"
    android:layout_width="match_parent"
    android:layout_height="match_parent"
    android:background="@android:color/transparent"
    android:orientation="vertical"
    android:padding="0dp"
    tools:context="com.send.apk.bluetoothappsend.MainActivity">

    <include
        android:id="@+id/tool_bar"
        layout="@layout/tool_bar" />

    <LinearLayout
        android:layout_width="match_parent"
        android:layout_height="match_parent"
        android:background="@drawable/background"
        android:orientation="vertical">

        <android.support.v7.widget.RecyclerView
            android:id="@+id/rv"
            android:layout_width="match_parent"
            android:layout_height="0dp"
            android:layout_weight="1" />

        <RelativeLayout
            android:layout_width="match_parent"
            android:layout_height="@dimen/_80sdp"
            android:background="@drawable/ic_footer" />
    </LinearLayout>


</LinearLayout>
