我想將漸變背景放到textView。但是，當我運行它，我得到一個錯誤說：如何設置漸變作爲textview的背景？

我做了一個XML文件，下面的代碼：

<?xml version="1.0" encoding="utf-8"?> 
<selector xmlns:android="http://schemas.android.com/apk/res/android"> 
<item> 
    <shape> 
    <gradient 
     android:startColor="@color/mainPinkStart" 
     android:endColor="@color/mainPinkEnd" 
     android:angle="125" /> 
    </shape> 
</item> 
</selector>

，我的主要活動代碼：

<?xml version="1.0" encoding="utf-8"?> 
<RelativeLayout 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:paddingBottom="@dimen/activity_vertical_margin" 
android:paddingTop="@dimen/activity_vertical_margin" 
tools:context="cresol.deal.MainActivity"> 
<LinearLayout 
    android:layout_width="match_parent" 
    android:layout_height="200dp" 
    android:orientation="vertical"> 
<HorizontalScrollView 
    android:layout_width="wrap_content" 
    android:layout_height="wrap_content" 
    android:overScrollMode="never" 
    android:scrollbars="none" 
    android:id="@+id/horizontalScrollView"> 

    <LinearLayout 
     android:layout_width="match_parent" 
     android:layout_height="wrap_content" 
     android:layout_marginLeft="15dp" 
     android:layout_marginRight="15dp" 
     android:orientation="horizontal" 

     android:layout_alignParentTop="true" 
     android:layout_alignParentStart="true"> 

     <ImageButton 
      android:layout_width="wrap_content" 
      android:layout_height="wrap_content" 
      android:src="@drawable/home_unpressed" 
      android:background="@null" 
      android:id="@+id/main_imageButton_home" 
      /> 

    </LinearLayout> 
</HorizontalScrollView> 
</LinearLayout> 
<TextView 
    android:layout_width="100dp" 
    android:layout_height="100dp" 
    android:background="@drawable/main_pink_gradient"/> 

<android.support.v7.widget.CardView 
    xmlns:card_view="http://schemas.android.com/apk/res-auto" 
    android:layout_width="match_parent" 
    android:layout_height="100dp" 
    card_view:cardCornerRadius="20dp" 
    card_view:cardElevation="8dp" 
    card_view:cardMaxElevation="10dp" 
    card_view:cardBackgroundColor="#fff" 
    android:background="#a9a9a9" 
    android:layout_marginLeft="20dp" 
    android:layout_marginRight="20dp" 
    android:layout_alignParentBottom="true" 
    android:layout_centerHorizontal="true" 
    android:layout_marginBottom="30dp"> 

</android.support.v7.widget.CardView> 
</RelativeLayout>

我的顏色文件：

<?xml version="1.0" encoding="utf-8"?> 
<resources> 
<color name="colorPrimary">#3F51B5</color> 
<color name="colorPrimaryDark">#303F9F</color> 
<color name="colorAccent">#FF4081</color> 
<color name="mainPinkStart">#F44195</color> 
<color name="mainPinkEnd">#EE82FA</color> 
</resources>

我找不到這個地方正在發生的任何問題.... 我使用這個XML文件也試過：

<shape 
xmlns:android="http://schemas.android.com/apk/res/android" 
android:shape="rectangle"> 
<gradient 
    android:startColor="@color/mainPinkStart" 
    android:endColor="@color/mainPinkEnd" 
    android:angle="125" /> 
</shape>

但是這也沒有工作，我得到了同樣的錯誤。

是的，它說inflaterexception ..該XML文件中的哪一部分是錯誤的這使得它成爲一個例外...我所採用的代碼只是在StackOverflow問題中工作並回答了問題。 –

android:angle="125"

125不是45多個，45

支持角度的使用多個45,90,135,180,225,270,315,360

梯度標籤需要 '角度' 屬性是的倍數45

<shape 
xmlns:android="http://schemas.android.com/apk/res/android" 
android:shape="rectangle"> 
<gradient 
android:startColor="@color/mainPinkStart" 
android:endColor="@color/mainPinkEnd" 
android:angle="90" /> 
</shape>
