更改Chromecast投射圖標顏色

Question

我使用Google的方法將投射按鈕添加到我的應用，但默認爲白色圖標，這對我的白色菜單欄是不可見的。如何將Cast圖標的顏色更改爲黑色？

Answer 1

如果僅僅是由於風格（暗vs光）造成的，如果風格被正確定義（即延伸正確的主題，暗vs光），你應該沒問題。對於一般造型，請查看post，如果這樣不能解決您的問題，請回來告訴我們。

Answer 2

我自己也遇到過這個問題，並通過將android:theme和app:popuptheme的值更改爲@style/ThemeOverlay.AppCompat.Dark.ActionBar來解決此問題。

參見下面的示例代碼：

<android.support.v7.widget.Toolbar 
     android:id="@+id/my_toolbar" 
     android:layout_width="match_parent" 
     android:layout_height="?attr/actionBarSize" 
     android:background="#4dffffff" 
     android:elevation="4dp" 
     android:theme="@style/ThemeOverlay.AppCompat.Dark.ActionBar" 
     app:popupTheme="@style/ThemeOverlay.AppCompat.Dark.ActionBar"/> 

Answer 3

我擴展MediaRouteButton。見下面的代碼。然後，我可以叫applyTint（）和它的顏色應用到的RemoteIndicatorDrawable

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); 
    } 
}

所有國家我剛剛延長MediaRouteActionProvider這樣的：

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是什麼顏色我想了。

則只需更換actionProviderClass菜單從MediaRouteActionProvider你這樣的：

<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> 

Answer 5

絕對簡單答案在這裏：

所以只是複製mediaRouteTheme從鏈接到你的ap p的主題和接下來的兩個styles.xml樣式。
