我使用Google的方法将Cast按钮添加到我的应用中,但它默认为白色图标,在我的白色菜单栏上看不见。如何将Cast图标的颜色更改为黑色?
答案 0 :(得分:6)
我刚才扩展了MediaRouteActionProvider:
public class ThemeableMediaRouteActionProvider extends MediaRouteActionProvider {
public ThemeableMediaRouteActionProvider(Context context) {
super(context);
}
@Override
public MediaRouteButton onCreateMediaRouteButton() {
MediaRouteButton button = super.onCreateMediaRouteButton();
colorWorkaroundForCastIcon(button);
return button;
}
@Nullable
@Override
public MediaRouteButton getMediaRouteButton() {
MediaRouteButton button = super.getMediaRouteButton();
colorWorkaroundForCastIcon(button);
return button;
}
private void colorWorkaroundForCastIcon(MediaRouteButton button) {
if (button == null) return;
Context castContext = new ContextThemeWrapper(getContext(), android.support.v7.mediarouter.R.style.Theme_MediaRouter);
TypedArray a = castContext.obtainStyledAttributes(null,
android.support.v7.mediarouter.R.styleable.MediaRouteButton, android.support.v7.mediarouter.R.attr.mediaRouteButtonStyle, 0);
Drawable drawable = a.getDrawable(android.support.v7.mediarouter.R.styleable.MediaRouteButton_externalRouteEnabledDrawable);
a.recycle();
DrawableCompat.setTint(drawable, getContext().getResources().getColor(R.color.primary));
drawable.setState(button.getDrawableState());
button.setRemoteIndicatorDrawable(drawable);
}
}
R.color.primary是我想要的颜色。
然后将菜单中的actionProviderClass从MediaRouteActionProvider替换为:
<item
android:id="@+id/media_route_menu_item"
android:title="@string/media_route_menu_title"
bwq:actionProviderClass="tv.test.playback.chromecast.ThemeableMediaRouteActionProvider"
bwq:showAsAction="always">
</item>

我扩展了MediaRouteButton。见下面的代码。然后我可以调用applyTint()并将颜色应用于RemoteIndicatorDrawable的所有状态
public class ColorableMediaRouteButton extends MediaRouteButton {
protected Drawable mRemoteIndicatorDrawable;
public ColorableMediaRouteButton(Context context) {
super(context);
}
public ColorableMediaRouteButton(Context context, AttributeSet attrs) {
super(context, attrs);
}
public ColorableMediaRouteButton(Context context, AttributeSet attrs, int defStyleAttr) {
super(context, attrs, defStyleAttr);
}
@Override
public void setRemoteIndicatorDrawable(Drawable d) {
mRemoteIndicatorDrawable = d;
super.setRemoteIndicatorDrawable(d);
}
public void applyTint(int color) {
Drawable wrapDrawable = DrawableCompat.wrap(mRemoteIndicatorDrawable);
DrawableCompat.setTint(wrapDrawable, color);
}
}

如果只是由于风格(黑暗与光线),如果风格被正确定义(即在暗与光的方面扩展右主题),你应该没问题。对于一般样式,请查看此post,如果这不能解决您的问题,请回来告诉我们。

我自己遇到过这个问题,并通过将pip --version
和android:theme
值更改为app:popuptheme
来解决此问题。
请参阅下面的示例代码:
@style/ThemeOverlay.AppCompat.Dark.ActionBar

如果视图的投射图标只有一种颜色,请为片段或活动使用主题。
<item name="mediaRouteButtonTint">@color/red</item>
如果要通过编程方式设置颜色,请使用以下代码。
<menu xmlns:android="http://schemas.android.com/apk/res/android"
xmlns:app="http://schemas.android.com/apk/res-auto">
<item
android:id="@+id/menu_item"
android:title="@string/media_route_menu_title"
app:actionProviderClass="androidx.mediarouter.app.MediaRouteActionProvider" />
</menu>
import androidx.core.content.ContextCompat
import androidx.appcompat.view.ContextThemeWrapper
import androidx.core.graphics.drawable.DrawableCompat
...
override fun onCreateOptionsMenu(menu: Menu, inflater: MenuInflater?) {
val tintColor = ContextCompat.getColor(context, R.color.my_color)
val item = menu.findItem(R.id.menu_item)
val button = item.actionView
val castContext = ContextThemeWrapper(context, androidx.mediarouter.R.style.Theme_MediaRouter)
val attrs = castContext.obtainStyledAttributes(null, androidx.mediarouter.R.styleable.MediaRouteButton, androidx.mediarouter.R.attr.mediaRouteButtonStyle, 0)
val drawable = attrs.getDrawable(androidx.mediarouter.R.styleable.MediaRouteButton_externalRouteEnabledDrawable)
attrs.recycle()
DrawableCompat.setTint(drawable, tintColor)
drawable.state = button.getDrawableState()
button.setRemoteIndicatorDrawable(drawable)

绝对简单回答:
https://developers.google.com/cast/docs/android_sender_advanced#customize_cast_button
只需将 mediaRouteTheme 从该链接复制到您应用的主题,然后将两个样式复制到styles.xml。

官方答案在这里:
https://developers.google.com/cast/docs/android_sender/customize_ui#customize_cast_button
自定义投射按钮
要将自定义
mediaRouteTheme
添加到您应用的主题中:<style name="Theme.CastVideosTheme" parent="Theme.AppCompat.Light.NoActionBar"> <!-- ... --> <item name="mediaRouteTheme">@style/CustomMediaRouterTheme</item> </style>
声明您的自定义媒体路由器主题并声明一个自定义
mediaRouteButtonStyle
:如果支持库版本,则应使用<style name="CustomMediaRouterTheme" parent="Theme.MediaRouter"> <item name="mediaRouteButtonStyle">@style/CustomMediaRouteButtonStyle</item> </style> <style name="CustomMediaRouteButtonStyle" parent="Widget.MediaRouter.Light.MediaRouteButton"> <item name="mediaRouteButtonTint">#EEFF41</item> </style>
mediaRouteButtonTint
比26.0.0更新。对于较早的支持库版本,请使用buttonTint
。

如果以上解决方案均无效,请尝试此处说明的内容。您可能需要使用colorFilter属性而不是色调。
public void onCreateOptionsMenu(@NonNull Menu menu, @NonNull MenuInflater inflater) {
super.onCreateOptionsMenu(menu, inflater);
inflater.inflate(R.menu.some_menu, menu);
setColorForCast(menu);
}
private void setColorForCast(@NonNull Menu menu) {
MediaRouteButton castButton = (MediaRouteButton) menu.findItem(R.id.cast_button).getActionView();
if (castButton != null) {
Drawable drawable = getResources().getDrawable(R.drawable.chromecast);
int color = ContextCompat.getColor(getContext(), R.color.colorPrimary);
drawable.setColorFilter(color, PorterDuff.Mode.SRC_ATOP);
drawable.setState(castButton.getDrawableState());
castButton.setRemoteIndicatorDrawable(drawable);
}
}
