是否可以使用 android:DrawableRight 在按钮和 TextView 中使用 VectorDrawable？

Question

当我在文本视图或图像视图中使用 VectorDrawable 资源时，在使用 "android:DrawableRight" / "android:DrawableEnd" / "android:DrawableStart" / "android:DrawableLeft".[=17= 时出现运行时崩溃]

应用程序可以正常编译，没有任何警告。

我正在使用

Gradle 1.5
支持库 23.2 ('com.android.support:appcompat-v7:23.2.0')

不过我发现我可以在 Java 中以编程方式分配 SVG 而不会像这样崩溃。

TextView tv = (TextView) findViewById(R.id.textView);
tv.setCompoundDrawablesWithIntrinsicBounds(null,null, getResources().getDrawable(R.drawable.ic_accessible_white_36px),null);

（我怀疑这是 23.2 的支持库错误。）

但是是否可以将 drawableRight 等用于 SVG 资源？

这是我的布局

<?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:background="@color/colorPrimary"
    android:textColor="#FFFFFF"

        super.onCreate(savedInstanceState);
        setContentView(R.layout.activity_main);

        }
    }

这是来自 Google 的 material 设计网站的未修改的 VectorDrawable 资源。

Answer 1

这个解决方案不再正确。从 23.3.0 版本开始，矢量绘图只能通过 app:srcCompat 或 setImageResource()

加载

尝试将矢量可绘制对象包装到图层列表或选择器中：

<TextView
    android:id="@+id/textView"
    android:layout_width="match_parent"
    android:layout_height="wrap_content"
    android:drawableRight="@drawable/ic_accessible_white_wrapped"
    android:background="@color/colorPrimary"
    android:textColor="#FFFFFF"
    android:textSize="22sp"
    android:text="Hello World!"/>

ic_accessible_white_wrapped.xml:

<layer-list xmlns:android="http://schemas.android.com/apk/res/android">
    <item android:drawable="@drawable/ic_accessible_white_36px"/>
</layer-list>

Answer 2

From Google: As of Android Support Library 23.3.0, support vector drawables can only be loaded via app:srcCompat or setImageResource()..

http://android-developers.blogspot.ru/2016/02/android-support-library-232.html

Answer 3

可以在 xml 中直接设置矢量绘图，但您已经包含了数据绑定框架。

随便写

<TextView
...
android:drawableRight="@{@drawable/ic_accessible_white_36px}"/>

并将您的整个布局包裹在 <layout> 标记中，所以基本上您的 xml 看起来像：

<?xml version="1.0" encoding="utf-8"?>
<layout>

    <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:paddingLeft="@dimen/activity_horizontal_margin"
        android:paddingRight="@dimen/activity_horizontal_margin"
        android:paddingTop="@dimen/activity_vertical_margin"
        tools:context="au.com.angryitguy.testsvg.MainActivity">


        <TextView
            android:id="@+id/textView"
            android:layout_width="match_parent"
            android:layout_height="wrap_content"
            android:background="@color/colorPrimary"
            android:drawableRight="@{@drawable/ic_accessible_white_36px}"
            android:text="Hello World!"
            android:textColor="#FFFFFF"
            android:textSize="22sp"/>
    </RelativeLayout>
</layout>

要激活数据绑定框架，只需添加

android {
    ....
    defaultConfig {
        dataBinding {
            enabled = true
        }
    }
}

您不必使用绑定库的任何其他功能

编辑：

当然，如果您想使用 Lollipop 之前的矢量绘图，您必须启用支持矢量绘图使用

vectorDrawables.useSupportLibrary = true

所以您的 build.gradle 需要 2 个新命令：

android {
    ....
    defaultConfig {
        vectorDrawables.useSupportLibrary = true
        dataBinding {
            enabled = true
        }
    }
}

感谢的评论

Answer 4

it possible to use drawableRight etc for SVG assets ?

是

AppCompatTextView now 支持 app:drawableLeftCompat, app:drawableTopCompat, app:drawableRightCompat, app:drawableBottomCompat, app:drawableStartCompat 和 app:drawableEndCompat 复合绘图，支持向后移植的绘图类型，例如 VectorDrawableCompat.

将其包含在您的 gradle 文件中

implementation 'androidx.appcompat:appcompat:1.1.0-alpha01'

在您的文本视图中，您可以使用

app:drawableLeftCompat
app:drawableStartCompat

如果在按钮中使用 app:drawableLeftCompat、app:drawableStartCompat 时遇到问题，您需要将库更新为

androidx.appcompat:appcompat:1.2.0-alpha01

他们在

上有一个错误

androidx.appcompat:appcompat:1.1.0-alpha01

你可以看到 docs

或者如果您还不想更新，那么：

因为看起来 Google 短期内不会对这个问题做任何事情，所以我不得不为我的所有应用程序想出一个更可靠的可重用解决方案：

首先在您的应用 attrs.xml 文件中添加自定义 TextView 属性 "res/values/attrs.xml" :

<resources>
    <declare-styleable name="CustomTextView">
        <attr name="drawableStartCompat" format="reference"/>
        <attr name="drawableEndCompat" format="reference"/>
        <attr name="drawableTopCompat" format="reference"/>
        <attr name="drawableBottomCompat" format="reference"/>
    </declare-styleable>
</resources>

然后像这样创建自定义 TextView class：

import android.content.Context;
import android.content.res.TypedArray;
import android.graphics.drawable.Drawable;
import android.os.Build;
import android.support.v7.content.res.AppCompatResources;
import android.support.v7.widget.AppCompatTextView;
import android.util.AttributeSet;

public class CustomTextView extends AppCompatTextView {
    public CustomTextView(Context context) {
        super(context);
    }    
    public CustomTextView(Context context, AttributeSet attrs) {
        super(context, attrs);
        initAttrs(context, attrs);
    }
    public CustomTextView(Context context, AttributeSet attrs, int defStyleAttr) {
        super(context, attrs, defStyleAttr);
        initAttrs(context, attrs);
    }

    void initAttrs(Context context, AttributeSet attrs) {
        if (attrs != null) {
            TypedArray attributeArray = context.obtainStyledAttributes(
                    attrs,
                    R.styleable.CustomTextView);

            Drawable drawableStart = null;
            Drawable drawableEnd = null;
            Drawable drawableBottom = null;
            Drawable drawableTop = null;
            if (Build.VERSION.SDK_INT >= Build.VERSION_CODES.LOLLIPOP) {
                drawableStart = attributeArray.getDrawable(R.styleable.CustomTextView_drawableStartCompat);
                drawableEnd = attributeArray.getDrawable(R.styleable.CustomTextView_drawableEndCompat);
                drawableBottom = attributeArray.getDrawable(R.styleable.CustomTextView_drawableBottomCompat);
                drawableTop = attributeArray.getDrawable(R.styleable.CustomTextView_drawableTopCompat);
            } else {
                final int drawableStartId = attributeArray.getResourceId(R.styleable.CustomTextView_drawableStartCompat, -1);
                final int drawableEndId = attributeArray.getResourceId(R.styleable.CustomTextView_drawableEndCompat, -1);
                final int drawableBottomId = attributeArray.getResourceId(R.styleable.CustomTextView_drawableBottomCompat, -1);
                final int drawableTopId = attributeArray.getResourceId(R.styleable.CustomTextView_drawableTopCompat, -1);

                if (drawableStartId != -1)
                    drawableStart = AppCompatResources.getDrawable(context, drawableStartId);
                if (drawableEndId != -1)
                    drawableEnd = AppCompatResources.getDrawable(context, drawableEndId);
                if (drawableBottomId != -1)
                    drawableBottom = AppCompatResources.getDrawable(context, drawableBottomId);
                if (drawableTopId != -1)
                    drawableTop = AppCompatResources.getDrawable(context, drawableTopId);
            }

            // to support rtl
            setCompoundDrawablesRelativeWithIntrinsicBounds(drawableStart, drawableTop, drawableEnd, drawableBottom);
            attributeArray.recycle();
        }
    }
}

现在您可以通过自定义属性在任何布局中轻松使用它：

<YOUR_VIEW_PACKAGE.CustomTextView
    android:id="@+id/edt_my_edit_text"
    android:layout_width="wrap_content"
    android:layout_height="wrap_content"
    app:drawableStartCompat="@drawable/your_vector_drawable" <!-- vector drawable -->
    app:drawableEndCompat="@drawable/your_vector_drawable" <!-- vector drawable -->
    app:drawableTopCompat="@drawable/your_vector_drawable" <!-- vector drawable -->
    app:drawableBottomCompat="@drawable/your_vector_drawable" <!-- vector drawable -->
    />

你可以用 Button、EditText 和 RadioButton 做类似的事情，因为它们来自文本视图

希望对您有所帮助:)

Answer 5

如果您正在使用绑定，还有另一种神奇的方法可以使用相同的方法在 TextView 中使用向量。像这样包装它们：

android:drawableLeft="@{@drawable/vector_ic_access_time_24px}"
android:drawableStart="@{@drawable/vector_ic_access_time_24px}"

这将神奇地起作用，我没有调查幕后发生的事情，但我猜 TextView 正在使用 AppCompatResources 或类似方法中的 getDrawable 方法。

Answer 6

我找到的最佳方法：

Drawable leftDrawable = AppCompatResources.getDrawable(this, R.drawable.ic_search);
search.setCompoundDrawablesWithIntrinsicBounds(leftDrawable, null, null, null);

Answer 7

为了补充此处的一些答案：您可以让 VectorDrawable 像 drawableLeft 一样工作（等等），但这取决于支持库的版本，并且需要付费。

在什么情况下有效？我已经 this diagram 提供帮助（对支持库 23.4.0 至 - 至少 - 25.1.0 有效）。

Answer 8

我很晚才回答这个问题，因为我迟迟没有解决这个问题。我对带有 TextView 的 svg/vector 可绘制对象有同样的问题。我可以使用以下两行代码解决我的问题，而不是制作您自己的自定义可绘制对象：

Drawable drawableTop = AppCompatResources.getDrawable(view.getContext(), iconId);
view.setCompoundDrawablesWithIntrinsicBounds(null, drawableTop, null, null);

希望对您有所帮助。

Answer 9

None 的其他答案有效，这是我将 VectorDrawable 添加到 TextView 的方法，您应该在处理 [=14] 时使用 VectorDrawableCompat.create() =] 下面 Android L:

TextView titleTextView = (TextView) viewHolder.getView(android.R.id.text1);
if (Build.VERSION.SDK_INT >= Build.VERSION_CODES.LOLLIPOP)
{
       Drawable leftDrawable = AppCompatResources
                            .getDrawable(context, R.drawable.ic_tickbox);
       titleTextView.setCompoundDrawablesWithIntrinsicBounds(leftDrawable, null, null, null);
}
else
{
      //Safely create our VectorDrawable on pre-L android versions. 
       Drawable leftDrawable = VectorDrawableCompat
                            .create(context.getResources(), R.drawable.ic_tickbox, null);
       titleTextView.setCompoundDrawablesWithIntrinsicBounds(leftDrawable, null, null, null);
}

简短、甜美、切中要点！

Answer 10

我为此设计了一个小型库 - textview-rich-drawable（它还支持定义复合绘图的大小和色调）。

<com.tolstykh.textviewrichdrawable.TextViewRichDrawable
    android:layout_width="wrap_content"
    android:layout_height="wrap_content"
    android:text="Some text"
    app:compoundDrawableHeight="24dp"
    app:compoundDrawableWidth="24dp"
    app:drawableTopVector="@drawable/some_vector_drawble"
    app:drawableEndVector="@drawable/another_vector_drawable"
    app:drawableTint="@color/colorAccent" />

和依赖关系

compile 'com.tolstykh.textviewrichdrawable:textview-rich-drawable:0.3.2'

Answer 11

我查看了所有答案并使用了最新的 Android studio 3.0.1 和 AppCompat Support Library 26.1.0 我可以保证这一切正常。

在build.gradle（应用程序）文件中

android {
    compileSdkVersion 26
    defaultConfig {
        vectorDrawables.useSupportLibrary = true
    }
}

dependencies {
    implementation 'com.android.support:appcompat-v7:26.1.0'
}

并在 Activity 中扩展 AppcompatActivity 将其包含在外部方法，即 static 块

static {
    AppCompatDelegate.setCompatVectorFromResourcesEnabled(true);
}

或者如果您希望将其应用于整个应用程序，只需在其中包含此行 class 扩展 Application class

override fun onCreate() {
    super.onCreate()
    AppCompatDelegate.setCompatVectorFromResourcesEnabled(true)
}

xml

中的文本视图

<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="wrap_content"
    android:gravity="center"
    android:orientation="vertical">

<TextView
        android:id="@+id/passName"
        android:layout_width="match_parent"
        android:layout_height="wrap_content"
        android:drawableLeft="@drawable/account_drawableleft_selector"
        android:drawablePadding="5dp"
        android:ellipsize="marquee"
        android:fontFamily="@font/montserrat_light_family"
        android:gravity="center_vertical"
        android:marqueeRepeatLimit="marquee_forever"
        android:paddingRight="10dp"
        android:scrollHorizontally="true"
        android:singleLine="true"
        android:textColor="@color/app_text_color"
        android:textSize="12sp"
        tools:text="Account Name" />
</LinearLayout>

account_drawableleft_selector.xml

<?xml version="1.0" encoding="utf-8"?>
<selector xmlns:android="http://schemas.android.com/apk/res/android">
    <item android:drawable="@drawable/ic_account_circle_24dp" /> <!-- checked -->
</selector>

Answer 12

在 build.gradle（应用程序）文件中

android {
    compileSdkVersion 26
    defaultConfig {
        vectorDrawables.useSupportLibrary = true
    }

    dataBinding {
        enabled = true
    }
}

...

public class BindingUtils {
    @BindingAdapter("android:drawableRight")
    public static void setDrawableStart(TextView textView, int resourceId) {
        Drawable drawable = AppCompatResources.getDrawable(textView.getContext(), resourceId);
        Drawable[] drawables = textView.getCompoundDrawables();
        textView.setCompoundDrawablesWithIntrinsicBounds(drawable,
                drawables[1], drawables[2], drawables[3]);
    } 
}

使用（数据绑定时）

android:drawableRight="@{viewModel.ResId}"

或（正常）

android:drawableRight="@{@drawable/ic_login_24dp}"

Answer 13

根据 Behzad Bahmanyar 的，我注意到我无法对普通 png 文件使用 android 的普通属性：

android:drawableTop
android:drawableBottom
etc

因为在

中会被null替换

Drawable drawableTop = null;
...
setCompoundDrawablesRelativeWithIntrinsicBounds(drawableStart, drawableTop, drawableEnd, drawableBottom);

如果未设置 app:drawableTopCompat，但设置了 android:drawableTop（例如）。

这是完整的解决方案：

public class CustomTextView extends AppCompatTextView {
    private static final int NOT_SET = -1;
    private static final int LEFT = 0;
    private static final int START = 0;
    private static final int TOP = 1;
    private static final int RIGHT = 2;
    private static final int END = 2;
    private static final int BOTTOM = 3;

    public CustomTextView(Context context) {
        super(context);
    }

    public CustomTextView(Context context, AttributeSet attrs) {
        super(context, attrs);
        initAttrs(context, attrs);

使用矢量绘图使用

科特林

 val drawable1 = VectorDrawableCompat.create(resources, R.drawable.ic_rb_username, theme)
        yourView.setCompoundDrawablesRelativeWithIntrinsicBounds( drawable1, null, null, null)

java

  Drawable drawable1 = VectorDrawableCompat.create(getResources(), R.drawable.ic_rb_username, getTheme());
        yourView.setCompoundDrawablesRelativeWithIntrinsicBounds( drawable1, null, null, null);

Answer 15

从 androidx.appcompat:appcompat:1.1.0 开始，您可以使用

app:drawableLeftCompat
app:drawableStartCompat
...

Answer 16

为了向后兼容使用：

TextViewCompat.setCompoundDrawablesRelativeWithIntrinsicBounds(textView, left, top, right, bottom)

Answer 17

我正在使用绑定适配器来解决这个问题

@JvmStatic
@BindingAdapter("drawableSvgLeft")
fun addDrawableSvgLeft(textView: TextView,drawable: Drawable){
    textView.setCompoundDrawablesWithIntrinsicBounds(drawable,null,null,null)
}

@JvmStatic
@BindingAdapter("drawableSvgRight")
fun addDrawableSvgRight(textView: TextView,drawable: Drawable){
    textView.setCompoundDrawablesWithIntrinsicBounds(null,null,drawable,null)
}

并且在我的布局中也以这种方式使用

<TextView
  drawableSvgRight="@{@drawable/svg_ic_battle_trophy}"
  .....

可能 vectorDrawables.useSupportLibrary = 正确默认配置是必需的

是否可以使用 android:DrawableRight 在按钮和 TextView 中使用 VectorDrawable？

Is it possible to use VectorDrawable in Buttons and TextViews using android:DrawableRight?

java

android

android-layout

android-vectordrawable

compound-drawables
