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"/>

去mainactivity。java 和下面这段代码-> NavigationView NavigationView = findViewById(R.id.nav_view); 添加单行代码-> navigationView.setItemIconTintList(null); 也就是我代码的最后一行

我希望这能解决你的问题。

public class MainActivity extends AppCompatActivity {

    private AppBarConfiguration mAppBarConfiguration;
    @Override
    protected void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.activity_main);

        Toolbar toolbar = findViewById(R.id.toolbar);
        setSupportActionBar(toolbar);

        DrawerLayout drawer = findViewById(R.id.drawer_layout);
        NavigationView navigationView = findViewById(R.id.nav_view);
        navigationView.setItemIconTintList(null);

目前可行的解决方案是 android: fillColor = " # FFFFFF "

除了在向量中硬编码,什么都不管用

<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"/>

然而,填充色和色调可能很快就会起作用。请参阅此讨论以了解更多信息:

https://code.google.com/p/android/issues/detail?id=186431

此外,颜色可能会粘在缓存中,所以删除所有用户的应用程序可能会有所帮助。

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);

如果你想支持旧版前棒棒糖

使用相同的XML代码,只是做了一些更改

而不是普通的ImageView——> AppCompatImageView

而不是android:src——> app:srcCompat

这里有一个例子

<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" />

别忘了更新你的gradle @ Sayooj Valsan提到

// Gradle Plugin 2.0+ android { defaultConfig { vectorDrawables。useSupportLibrary = true } } 编译“com.android.support:设计:23.4.0”

注意:对于任何一个使用矢量,永远永远不要给你的矢量引用颜色,就像这个android:fillColor="@color/primary"给出它的十六进制值。

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>

这是由Filipe绘制的Kotlin版本的Helper

class DrawableHelper(var mContext: Context) {
    @ColorRes
    private var mColor = 0
    private lateinit var mDrawable: Drawable
    private lateinit var mWrappedDrawable: Drawable
    fun withDrawable(@DrawableRes drawableRes: Int): DrawableHelper {
        mDrawable = getDrawable(mContext, drawableRes)!!
        return this
    }

    fun withDrawable(drawable: Drawable): DrawableHelper {
        mDrawable = drawable
        return this
    }

    @SuppressLint("ResourceType")
    fun withColor(@ColorRes colorRes: Int): DrawableHelper {
        mColor = ContextCompat.getColor(mContext, colorRes)
        return this
    }

    @SuppressLint("ResourceAsColor")
    fun tint(): DrawableHelper {
        mWrappedDrawable = DrawableCompat.wrap(mWrappedDrawable)
        DrawableCompat.setTint(mWrappedDrawable, mColor)
        DrawableCompat.setTintMode(mWrappedDrawable, PorterDuff.Mode.SRC_IN)
        return this
    }

    fun applyToBackground(view: View) {
        view.background = mWrappedDrawable
    }

    fun applyTo(imageView: ImageView) {
        imageView.setImageDrawable(mWrappedDrawable)
    }

    fun applyTo(menuItem: MenuItem) {
        menuItem.icon = mWrappedDrawable
    }

    fun get(): Drawable {
        return mWrappedDrawable
    }

    companion object {
        fun withContext(context: Context): DrawableHelper {
            return DrawableHelper(context)
        }
    }
}
