切换到gradle后，android自定义视图属性不起作用 [英] android custom view attributes not working after switch to gradle

问题描述

所以我最近迁移到了gradle，现在我的自定义视图属性返回null

so I recently migrated to gradle now my custom view attributes return null

我的项目看起来像这样

-custom_icon_view//包含具有自定义属性的自定义视图的库 --my application//这是实际使用自定义视图的主应用程序

--custom_icon_view // library that holds the custom view with custom attributes --my application // this is the main app that actually uses the custom view

在我的布局中，我的命名空间定义如下:

in my layout I have the namespace defined like this :

        xmlns:iconview="http://schemas.android.com/lib/be.webelite.iconview"

因为使用apk/res-auto会重新调整一条错误，指出无法识别出服装

because using apk/res-auto retuns an error saying attibutes could not be identified

这是我尝试获取xml中定义的图标名称的方法，这曾经可以完美地工作 但现在没有.而我改变的只是迁移到gradle.

this is how I try to get the icon name defined in xml, this used to work perfectlly but now it doesnt. and all I changed was migrating to gradle.

        final TypedArray a              = context.obtainStyledAttributes(attrs,be.webelite.iconview.R.styleable.icon);
        icon_name = a.getString(be.webelite.iconview.R.styleable.icon_name);

所以我猜我的gradle.build文件引起了问题吗?

so I'm guessing my gradle.build files are causing a problem?

我将库设置为

  apply plugin: 'android-library'

以

  apply plugin: 'android'

这已经让我头痛了2天了:(任何帮助/提示都非常贴心.

this has been giving me headache for 2 days now :( any help/hints are very apperciated.

这是我的gradle文件

here are my gradle files

这是文件夹结构

http://pastie.org/private/nvbzomx2zeagdpzt8qqjsq

这就是我在xml中声明视图的方式

this is how I declare my view in the xml

<LinearLayout
    xmlns:android="http://schemas.android.com/apk/res/android"
    <!-- tried res-auto didn't work -->
    xmlns:iconview="http://schemas.android.com/apk/lib/be.webelite.iconview"
    android:orientation="vertical" android:layout_width="match_parent"
    android:layout_height="match_parent"
    android:background="@color/background_gray">

    <be.webelite.iconview.IconView
        android:layout_width="wrap_content"
        android:layout_height="wrap_content"
        iconview:icon_name="entypo_search"
        android:textSize="25dp"/>

IconView> res>值目录中的

attrs.xml

attrs.xml in IconView>res>values directory

        <?xml version="1.0" encoding="utf-8"?>
        <resources>
            <declare-styleable name="icon">
                <attr name="name" format="string" />
            </declare-styleable>

        </resources>

推荐答案

无法真正看到项目中的问题.这是我使用自定义视图&的方法我的attrs:

Can't really see what's wrong in your project. Here is how I use custom view & attrs in mine :

在我的图书馆项目中:

attrs.xml:

attrs.xml :

<declare-styleable name="CustomFontSize">
    <attr name="typeFace" format="string" />
</declare-styleable>

在我的自定义课程中:

 TypedArray a = context.obtainStyledAttributes(attrs, R.styleable.CustomFontSize);
 if (a == null) {
      return;
 }
 CharSequence s = a.getString(R.styleable.CustomFontSize_typeFace);
 if (s != null) {
    // do something
 }

在我的主项目中，我的一个布局示例:

In my Main Project here an example of one of my layout :

<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
              xmlns:custom="http://schemas.android.com/apk/res-auto"
              android:layout_width="match_parent"
              android:layout_height="wrap_content"
              android:orientation="vertical"
              android:paddingLeft="@dimen/border_margin_pulltorefresh"
              android:paddingRight="@dimen/border_margin_pulltorefresh"
              android:paddingBottom="@dimen/divider_height">


    <com.custom.view.TextViewFont
            style="@style/DateStyle"
            android:id="@+id/news_date"
            android:shadowColor="@color/white"
            android:layout_gravity="center_vertical"
            android:gravity="center_vertical"
            custom:typeFace="@string/font_roboto_condensed_bold"/>

</LinearLayout>

希望这会有所帮助...

Hope it will help ...

在我的主项目"的build.gradle中

in my build.gradle of my "main project"

dependencies {
    compile project(":MyLibraryProject")
}

这是我的库的build.gradle:

And here the build.gradle of my library :

buildscript {
    repositories {
        mavenCentral()
    }
    dependencies {
        classpath 'com.android.tools.build:gradle:0.7.+'
    }
}
apply plugin: 'android-library'

repositories {
    mavenCentral()
}

dependencies {
    compile fileTree(dir: 'libs', include: '*.jar')
    compile 'com.android.support:support-v4:19.0.0'
    compile 'com.actionbarsherlock:actionbarsherlock:4.4.0@aar'
    compile project(':WebediaCore:dependencies:DataDroid')
    compile project(':WebediaCore:dependencies:ViewPagerIndicator')
    compile project(':WebediaCore:dependencies:ActionBar-PullToRefresh')
    compile project(':WebediaCore:dependencies:Android-Universal-Image-Loader')
}

android {
    compileSdkVersion 19
    buildToolsVersion '19'

    defaultConfig {
        minSdkVersion 8
        targetSdkVersion 19
    }
}

尝试使用此命名空间:

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

并替换:

 iconview:icon_name="entypo_search"

作者:

 custom:name="entypo_search"
