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"/>

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);
use
android:drawableTint="@color/primary"
在activity_main.xml
对于我的ImageButton，我使用app:tint="@color/green"而不是android:tint
<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>
将这个库添加到Gradle中，以启用旧android设备中的颜色向量可绘制。
compile 'com.android.support:palette-v7:26.0.0-alpha1'
和重新同步gradle。我认为这会解决问题。
