private ColorFilterDimmer(ColorFilterCache dimmer, float activeLevel, float dimmedLevel) mColorDimmer = dimmer; if (activeLevel > 1.0f) activeLevel = 1.0f; if (activeLevel < 0.0f) activeLevel = 0.0f; if (dimmedLevel > 1.0f) dimmedLevel = 1.0f; if (dimmedLevel < 0.0f) dimmedLevel = 0.0f; mActiveLevel = activeLevel; mDimmedLevel = dimmedLevel; mPaint = new Paint();

Methods Summary
public void	applyFilterToView(android.view.View view) Apply current the ColorFilter to a View. This method will set the hardware layer of the view when applying a filter, and remove it when not applying a filter. param view The View to apply the ColorFilter to. if (mFilter != null) { view.setLayerType(View.LAYER_TYPE_HARDWARE, mPaint); } else { view.setLayerType(View.LAYER_TYPE_NONE, null); } // FIXME: Current framework has bug that not triggering invalidate when change layer // paint. Will add conditional sdk version check once bug is fixed in released // framework. view.invalidate();
public static android.support.v17.leanback.graphics.ColorFilterDimmer	create(ColorFilterCache dimmer, float activeLevel, float dimmedLevel) Creates a ColorFilterDimmer for the given color and levels.. param dimmer The ColorFilterCache for dim color. param activeLevel The level of dimming when the View is in its active state. Must be a float value between 0.0 and 1.0. param dimmedLevel The level of dimming when the View is in its dimmed state. Must be a float value between 0.0 and 1.0. return new ColorFilterDimmer(dimmer, activeLevel, dimmedLevel);
public static android.support.v17.leanback.graphics.ColorFilterDimmer	createDefault(android.content.Context context) Creates a default ColorFilterDimmer. Uses the default color and level for the dimmer. param context A Context used to retrieve Resources. return A ColorFilterDimmer with the default dim color and levels. TypedArray a = context.obtainStyledAttributes(R.styleable.LeanbackTheme); int dimColor = a.getColor(R.styleable.LeanbackTheme_overlayDimMaskColor, context.getResources().getColor(R.color.lb_view_dim_mask_color)); float activeLevel = a.getFraction(R.styleable.LeanbackTheme_overlayDimActiveLevel, 1, 1, context.getResources().getFraction(R.fraction.lb_view_active_level, 1, 0)); float dimmedLevel = a.getFraction(R.styleable.LeanbackTheme_overlayDimDimmedLevel, 1, 1, context.getResources().getFraction(R.fraction.lb_view_dimmed_level, 1, 1)); a.recycle(); return new ColorFilterDimmer(ColorFilterCache.getColorFilterCache( dimColor), activeLevel, dimmedLevel);
public android.graphics.ColorFilter	getColorFilter() Gets the ColorFilter set to the current dim level. return The current ColorFilter. return mFilter;
public android.graphics.Paint	getPaint() Gets the Paint object set to the current dim level. return The current Paint object. return mPaint;
public void	setActiveLevel(float level) Sets the active level of the dimmer. Updates the ColorFilter based on the level. param level A float between 0 (fully dim) and 1 (fully active). if (level < 0.0f) level = 0.0f; if (level > 1.0f) level = 1.0f; mFilter = mColorDimmer.getFilterForLevel( mDimmedLevel + level * (mActiveLevel - mDimmedLevel)); mPaint.setColorFilter(mFilter);
