在Android Studio中改变矢量资产的颜色。

Android Studio now supports vector assets on 21+ and will generate pngs for lower versions at compile time. I have a vector asset (from the Material Icons) that I want to change the fill color. This works on 21+, but the generated pngs do not change color. Is there a way to do this?

Android Studio现在支持21+上的向量资产，并将在编译时为较低的版本生成png。我有一个矢量资产(来自材质图标)，我想要改变填充颜色。这适用于21+，但是生成的pngs不会改变颜色。有办法吗?

<vector android:height="48dp" android:viewportHeight="24.0"
android:viewportWidth="24.0" android:width="48dp" xmlns:android="http://schemas.android.com/apk/res/android">
<path android:fillColor="@color/primary" android:pathData="M9,16.17L4.83,12l-1.42,1.41L9,19 21,7l-1.41,-1.41z"/>

#1

Don't edit the vector assets directly. If you using a vector drawable in an ImageButton, just choose your color in android:tint.

不要直接编辑矢量资产。如果在ImageButton中使用矢量绘制，只需在android中选择颜色:tint。

<ImageButton
        android:layout_width="48dp"
        android:layout_height="48dp"
        android:id="@+id/button"
        android:src="@drawable/ic_more_vert_24dp"
        android:tint="@color/primary" />

#2

You can do it.

你能做到。

BUT you cannot use @color references for colors (..lame), otherwise it will work only for L+

但是不能对颜色(.. .lame)使用@color引用，否则只能用于L+

<vector xmlns:android="http://schemas.android.com/apk/res/android"
    android:width="24dp"
    android:height="24dp"
    android:viewportWidth="24.0"
    android:viewportHeight="24.0">
<path
    android:fillColor="#FFAABB"
    android:pathData="M15.5,14h-0.79l-0.28,-0.27C15.41,12.59 16,11.11 16,9.5 16,5.91 13.09,3 9.5,3S3,5.91 3,9.5 5.91,16 9.5,16c1.61,0 3.09,-0.59 4.23,-1.57l0.27,0.28v0.79l5,4.99L20.49,19l-4.99,-5zm-6,0C7.01,14 5,11.99 5,9.5S7.01,5 9.5,5 14,7.01 14,9.5 11.99,14 9.5,14z"/>

As said in other answers, don't edit the vector drawable directly, instead you can tint in java code, like that:

如其他答案所述，不要直接编辑矢量绘图，而是可以在java代码中着色，如下所示:

    mWrappedDrawable = mDrawable.mutate();
    mWrappedDrawable = DrawableCompat.wrap(mWrappedDrawable);
    DrawableCompat.setTint(mWrappedDrawable, mColor);
    DrawableCompat.setTintMode(mWrappedDrawable, PorterDuff.Mode.SRC_IN);

And for the sake of simplicity, I have created a helper class:

为了简单起见，我创建了一个助手类:

import android.content.Context;
import android.graphics.PorterDuff;
import android.graphics.drawable.Drawable;
import android.os.Build;
import android.support.annotation.ColorRes;
import android.support.annotation.DrawableRes;
import android.support.annotation.NonNull;
import android.support.v4.content.ContextCompat;
import android.support.v4.graphics.drawable.DrawableCompat;
import android.view.MenuItem;
import android.view.View;
import android.widget.ImageView;

/**
 * {@link Drawable} helper class.

 * @author Filipe Bezerra
 * @version 18/01/2016
 * @since 18/01/2016
 */
public class DrawableHelper {
    @NonNull Context mContext;
    @ColorRes private int mColor;
    private Drawable mDrawable;
    private Drawable mWrappedDrawable;

    public DrawableHelper(@NonNull Context context) {
        mContext = context;
    }

    public static DrawableHelper withContext(@NonNull Context context) {
        return new DrawableHelper(context);
    }

    public DrawableHelper withDrawable(@DrawableRes int drawableRes) {
        mDrawable = ContextCompat.getDrawable(mContext, drawableRes);
        return this;
    }

    public DrawableHelper withDrawable(@NonNull Drawable drawable) {
        mDrawable = drawable;
        return this;
    }

    public DrawableHelper withColor(@ColorRes int colorRes) {
        mColor = ContextCompat.getColor(mContext, colorRes);
        return this;
    }

    public DrawableHelper tint() {
        if (mDrawable == null) {
            throw new NullPointerException("É preciso informar o recurso drawable pelo método withDrawable()");
        }

        if (mColor == 0) {
            throw new IllegalStateException("É necessário informar a cor a ser definida pelo método withColor()");
        }

        mWrappedDrawable = mDrawable.mutate();
        mWrappedDrawable = DrawableCompat.wrap(mWrappedDrawable);
        DrawableCompat.setTint(mWrappedDrawable, mColor);
        DrawableCompat.setTintMode(mWrappedDrawable, PorterDuff.Mode.SRC_IN);

        return this;
    }

    @SuppressWarnings("deprecation")
    public void applyToBackground(@NonNull View view) {
        if (mWrappedDrawable == null) {
            throw new NullPointerException("É preciso chamar o método tint()");
        }

        if(Build.VERSION.SDK_INT >= Build.VERSION_CODES.JELLY_BEAN) {
            view.setBackground(mWrappedDrawable);
        } else {
            view.setBackgroundDrawable(mWrappedDrawable);
        }
    }

    public void applyTo(@NonNull ImageView imageView) {
        if (mWrappedDrawable == null) {
            throw new NullPointerException("É preciso chamar o método tint()");
        }

        imageView.setImageDrawable(mWrappedDrawable);
    }

    public void applyTo(@NonNull MenuItem menuItem) {
        if (mWrappedDrawable == null) {
            throw new NullPointerException("É preciso chamar o método tint()");
        }

        menuItem.setIcon(mWrappedDrawable);
    }

    public Drawable get() {
        if (mWrappedDrawable == null) {
            throw new NullPointerException("É preciso chamar o método tint()");
        }

        return mWrappedDrawable;
    }
}

To use just do the following:

要使用以下方法:

    DrawableHelper
            .withContext(this)
            .withColor(R.color.white)
            .withDrawable(R.drawable.ic_search_24dp)
            .tint()
            .applyTo(mSearchItem);

Or:

或者:

    final Drawable drawable = DrawableHelper
            .withContext(this)
            .withColor(R.color.white)
            .withDrawable(R.drawable.ic_search_24dp)
            .tint()
            .get();

    actionBar.setHomeAsUpIndicator(drawable);

To change vector image color you can directly use android:tint="@color/colorAccent"

要改变矢量图像的颜色，你可以直接使用android:tint="@color/colorAccent"

<ImageView
        android:id="@+id/ivVectorImage"
        android:layout_width="wrap_content"
        android:layout_height="wrap_content"
        android:src="@drawable/ic_account_circle_black_24dp"
        android:tint="@color/colorAccent" />

To change color programatically

语法上改变颜色

ImageView ivVectorImage = (ImageView) findViewById(R.id.ivVectorImage);
ivVectorImage.setColorFilter(getResources().getColor(R.color.colorPrimary));

#5

Currently the working soloution is android:fillColor="#FFFFFF"

目前的工作解决方案是android:fillColor="# ffff "

Nothing worked for me except hard coding in the vector

除了在向量中进行硬编码外，我什么都做不到

<vector xmlns:android="http://schemas.android.com/apk/res/android"
    android:width="24dp"
    android:height="24dp"
    android:viewportWidth="24.0"
      android:fillColor="#FFFFFF"
    android:viewportHeight="24.0">
<path
    android:fillColor="#FFFFFF"
    android:pathData="M15.5,14h-0.79l-0.28,-0.27C15.41,12.59 16,11.11 16,9.5 16,5.91 13.09,3 9.5,3S3,5.91 3,9.5 5.91,16 9.5,16c1.61,0 3.09,-0.59 4.23,-1.57l0.27,0.28v0.79l5,4.99L20.49,19l-4.99,-5zm-6,0C7.01,14 5,11.99 5,9.5S7.01,5 9.5,5 14,7.01 14,9.5 11.99,14 9.5,14z"/>

However, fillcolor and tint might work soon. Please see this discussion for more information:

不过，fillcolor和tint可能很快就会奏效。有关更多信息，请参阅本讨论:

Also the colors mighr stick in the cache so deleting app for all users might help.

另外，颜色可能会粘在缓存中，因此为所有用户删除应用程序可能会有所帮助。

Android studio now supports vectors pre-lollipop. No PNG conversion. You can still change your fill color and it will work.

Android studio现在支持向量机。没有PNG转换。你仍然可以改变你的填充颜色，它将会工作。

In you ImageView, use

在你ImageView,使用

 app:srcCompat="@drawable/ic_more_vert_24dp"

In your gradle file,

在你gradle文件,

 // Gradle Plugin 2.0+  
 android {  
   defaultConfig {  
     vectorDrawables.useSupportLibrary = true  
   }  
 }  

 compile 'com.android.support:design:23.4.0'

#7

if you look to support old version pre lolipop

如果您希望支持旧版本的pre lolipop

use the same xml code with some changes

使用相同的xml代码进行一些更改

instead of normal ImageView --> AppCompatImageView

而不是普通的ImageView——> AppCompatImageView。

instead of android:src --> app:srcCompat

而不是android:src——> app:srcCompat

here is example

下面是例子

<android.support.v7.widget.AppCompatImageView
        android:layout_width="48dp"
        android:layout_height="48dp"
        android:id="@+id/button"
        app:srcCompat="@drawable/ic_more_vert_24dp"
        android:tint="@color/primary" />

dont forget update your gradle as @ Sayooj Valsan mention

别忘了更新你的gradle，就像@ Sayooj Valsan提到的那样。

// Gradle Plugin 2.0+  
 android {  
   defaultConfig {  
     vectorDrawables.useSupportLibrary = true  
   }  
 }  

 compile 'com.android.support:design:23.4.0'

Notice To any one use vector dont ever ever never give your vector reference to color like this one android:fillColor="@color/primary" give its hex value .

注意，对于任何使用矢量的人，永远不要给你的矢量引用像这样的颜色:fillColor="@color/primary"给出十六进制值。

#8

Add this library to the Gradle to enable color vector drawable in old android Devices.

将这个库添加到Gradle中，可以在旧的android设备中绘制颜色向量。

compile 'com.android.support:palette-v7:26.0.0-alpha1'

and re sync gradle. I think it will solve the problem.

和再保险gradle同步。我认为这将解决问题。

#9

Update: AppCompat support

Other answers suspecting if android:tint will work on only 21+ devices only, AppCompat(v23.2.0 and above) now provides a backward compatible handling of tint attribute.

如果android:tint只能在21个以上的设备上运行，那么其他的答案可能会怀疑，AppCompat(v23.2.0及以上版本)现在提供了对tint属性的向后兼容处理。

So, the course of action would be to use AppCompatImageView and app:srcCompat(in AppCompat namespace) instead of android:src(Android namespace).

因此，我们将使用AppCompatImageView和app:srcCompat(在AppCompat名称空间中)而不是android:src(android名称空间)。

Here is an example:

这是一个例子:

<android.support.v7.widget.AppCompatImageView
        android:id="@+id/credits_material_icon"
        android:layout_width="20dp"
        android:layout_height="20dp"
        android:layout_marginBottom="8dp"
        android:layout_marginLeft="16dp"
        android:layout_marginStart="16dp"
        android:scaleType="fitCenter"
        android:tint="#ffd2ee"
        app:layout_constraintBottom_toBottomOf="parent"
        app:layout_constraintLeft_toLeftOf="parent"
        app:srcCompat="@drawable/ic_dollar_coin_stack" />

And don't forget to enable vector drawable support in gradle:

并且别忘了在gradle中启用矢量可拉支持:

vectorDrawables.useSupportLibrary = true 

#10

If the vectors are not showing individually set colors using fillColor then they may be being set to a default widget parameter.

如果向量没有使用fillColor显示单独设置的颜色，那么它们可能被设置为一个默认的小部件参数。

Try adding app:itemIconTint="@color/lime" to activity_main.xml to set a default color type for the widget icons.

尝试添加应用:itemIconTint="@color/lime"到activity_main。为小部件图标设置默认的颜色类型。
