在Android Studio中更改矢量资产的填充颜色

Question

Android Studio现在支持21岁以上的矢量资产,并将在编译时为较低版本生成png.我有一个矢量资源(来自材料图标)我想要更改填充颜色.这适用于21+,但生成的png不会改变颜色.有没有办法做到这一点？

<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"/>

Answer 1

不要直接编辑矢量资产.如果您在ImageButton中使用矢量drawable,只需选择您的颜色android: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" />

Answer 2

你能行的.

但是你不能使用@color参考颜色(..lame),否则它只适用于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"/>

Answer 3

正如在其他答案中所说,不要直接编辑矢量drawable,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);

为了简单起见,我创建了一个帮助类:

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;
    }
}

要使用,请执行以下操作:

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

要么:

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

    actionBar.setHomeAsUpIndicator(drawable);

Answer 4

要更改矢量图像颜色,您可以直接使用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" />

以编程方式更改颜色

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

Answer 5

目前工作解决方案是android:fillColor ="#FFFFFF"

除了向量中的硬编码之外,没有什么比我更有用了

<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"/>

但是,fillcolor和色调可能很快就会起作用.有关更多信息,请参阅此讨论:

此外,颜色仍然存在于缓存中,因此删除所有用户的应用程序可能会有所帮助.

Answer 6

更新：AppCompat支持

其他怀疑是否android:tint仅适用于 21+ 设备的答案，AppCompat（v23.2.0 及更高版本）现在提供向后兼容的 tint 属性处理。

因此，操作过程是使用AppCompatImageViewand app:srcCompat（在 AppCompat 命名空间中）而不是android:src（Android 命名空间）。

这是一个示例（AndroidX：这是androidx.appcompat.widget.AppCompatImageView ;））：

<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" />

并且不要忘记在 gradle 中启用矢量可绘制支持：

vectorDrawables.useSupportLibrary = true 

Answer 7

Android工作室现在支持矢量pre-lollipop.没有PNG转换.您仍然可以更改填充颜色,它将起作用.

在ImageView中,使用

 app:srcCompat="@drawable/ic_more_vert_24dp"

在您的gradle文件中,

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

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