我在我的项目中使用 CollapsingToolbarLayout

CollapsingToolbarLayout 展开时,默认情况下它是白色的(即在 style.xml< 中的 android:textColorSecondary 中定义)。

我的问题:

I want to change my menu item icon color.

enter image description here这是我的代码:

xml文件:

<android.support.design.widget.AppBarLayout xmlns:android="http://schemas.android.com/apk/res/android"
xmlns:app="http://schemas.android.com/apk/res-auto"
android:id="@+id/appbar_layout"
android:layout_width="match_parent"
android:layout_height="200dp"
android:theme="@style/ThemeOverlay.AppCompat.Dark.ActionBar">

<android.support.design.widget.CollapsingToolbarLayout
android:layout_width="match_parent"
android:layout_height="match_parent"
app:contentScrim="?attr/colorPrimary"
app:layout_scrollFlags="scroll|exitUntilCollapsed"
app:titleEnabled="false">

<com.google.android.gms.maps.MapView
android:id="@+id/mapView"
android:layout_width="match_parent"
android:layout_height="match_parent"
android:scaleType="centerCrop"
app:layout_collapseMode="parallax" />

<android.support.v7.widget.Toolbar
android:id="@+id/toolbar"
android:layout_width="match_parent"
android:layout_height="?attr/actionBarSize"
app:layout_collapseMode="pin" />

</android.support.design.widget.CollapsingToolbarLayout>

主要 Activity 代码:

    AppBarLayout appBarLayout = findViewById(R.id.appbar_layout);
appBarLayout.addOnOffsetChangedListener(new AppBarLayout.OnOffsetChangedListener() {
boolean isShow;
int scrollRange = -1;

@Override
public void onOffsetChanged(AppBarLayout appBarLayout, int verticalOffset) {
if (scrollRange == -1) {
scrollRange = appBarLayout.getTotalScrollRange();
}
if (scrollRange + verticalOffset == 0) {
//collapse map
//TODO: change share icon color - set white share icon
isShow = true;
} else if (isShow) {
//expanded map
//TODO: change share icon color - set dark share icon
isShow = false;
}
}
});

到目前为止我尝试了什么:

  1. How to change toolbar icons color on collapsing

设置 toolbar.getNavigationIcon().setColorFilter(getResources().getColor(R.color.white), PorterDuff.Mode.SRC_ATOP); 但是它改变了后退按钮的颜色,而我想更改共享按钮图标颜色。

  1. Set Toolbar Icon Colour Programmatically

DrawableCompat.setTint 不适用于我的情况。

谢谢。

最佳答案

我会这样做:

private Drawable drawable;

public boolean onCreateOptionsMenu(Menu menu) {
getMenuInflater().inflate(R.menu.your_menu, menu);
drawable = menu.getItem(0).getIcon(); // set 0 if you have only one item in menu
//this also will work
//drawable = menu.findItem(your item id).getIcon();
//
if(drawable != null) {
drawable.mutate();
}
return true;
}

现在在onOffsetChanged

        @Override
public void onOffsetChanged(AppBarLayout appBarLayout, int verticalOffset) {
if (scrollRange == -1) {
scrollRange = appBarLayout.getTotalScrollRange();
}
if (scrollRange + verticalOffset == 0) {
//collapse map
//TODO: change share icon color - set white share icon
isShow = true;
drawable.setColorFilter(getResources().getColor(R.color.white), PorterDuff.Mode.SRC_ATOP);
} else if (isShow) {
//expanded map
//TODO: change share icon color - set dark share icon
isShow = false;
drawable.setColorFilter(getResources().getColor(R.color.shadow), PorterDuff.Mode.SRC_ATOP);
}
}
