Android Studio现在在21+上支持矢量资产,并将在编译时为低版本生成png。我有一个矢量资产(来自材质图标),我想改变填充颜色。这适用于21+,但生成的png不改变颜色。有办法做到这一点吗?

<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"/>

更新:AppCompat支持

其他答案怀疑android:tint将只在21+设备上工作,AppCompat(v23.2.0及以上)现在提供了向后兼容的tint属性处理。

因此,行动的过程将是使用AppCompatImageView和app:srcCompat(在AppCompat命名空间)而不是android:src(android命名空间)。

下面是一个例子(AndroidX: This is 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" />

别忘了在gradle中启用向量可绘制支持:

vectorDrawables.useSupportLibrary = true

不要直接编辑矢量资产。如果你在ImageButton中使用矢量绘图,只需在android:tint中选择你的颜色。

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

别忘了在gradle中启用向量可绘制支持:

vectorDrawables.useSupportLibrary = true 

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默认的小部件参数。

尝试在activity_main.xml中添加app:itemIconTint="@color/lime"来为小部件图标设置默认颜色类型。

<?xml version="1.0" encoding="utf-8"?>
<android.support.v4.widget.DrawerLayout xmlns:android="http://schemas.android.com/apk/res/android"
    xmlns:app="http://schemas.android.com/apk/res-auto"
    xmlns:tools="http://schemas.android.com/tools"
    android:id="@+id/drawer_layout"
    android:layout_width="match_parent"
    android:layout_height="match_parent"
    android:fitsSystemWindows="true"
    tools:openDrawer="start">

    <include
        layout="@layout/app_bar_main"
        android:layout_width="match_parent"
        android:layout_height="match_parent" />

    <android.support.design.widget.NavigationView
        android:id="@+id/nav_view"
        android:layout_width="wrap_content"
        android:layout_height="match_parent"
        android:layout_gravity="start"
        android:fitsSystemWindows="true"
        app:headerLayout="@layout/nav_header_main"
        app:itemIconTint="@color/lime"
        app:menu="@menu/activity_main_drawer" />

</android.support.v4.widget.DrawerLayout>

可记录的

对于那些不使用ImageView的人,下面的工作为我在一个普通的视图(因此行为应该复制在任何类型的视图)

<View
    android:background="@drawable/ic_reset"
    android:backgroundTint="@color/colorLightText" />

正如在其他回答中所说,不要直接编辑可绘制的向量,相反,你可以在java代码中着色,像这样:

    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helper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,只需执行以下步骤:

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

Or:

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

    actionBar.setHomeAsUpIndicator(drawable);
