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"/>

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" />
以编程方式改变颜色
ImageView ivVectorImage = (ImageView) findViewById(R.id.ivVectorImage);
ivVectorImage.setColorFilter(getResources().getColor(R.color.colorPrimary));

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);
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)
}
}
}
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:

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。
如果vector资产在CardView中，请尝试 card_view:tint="@color/secondary"在ImageView中。 注意:用你想要的颜色替换@color/secondary。
<vector xmlns:android="http://schemas.android.com/apk/res/android"
android:width="24dp"
android:height="24dp"
android:viewportWidth="24"
android:viewportHeight="24"
android:tint="//Your Color Code//">
<path
android:fillColor="@android:color/white"
android:pathData="M11,9.16V2c-5,0.5 -9,4.79 -9,10s4,9.5 9"/>
</vector>
