示例1: onDraw
import android.graphics.drawable.TransitionDrawable; //导入方法依赖的package包/类
@Override
public void onDraw(Canvas canvas) {
Drawable drawable = this.getDrawable();
if(drawable != null) {
if(drawable instanceof BitmapDrawable) {
if (isBitmapRecycled(drawable)) {
this.setImageDrawable(null);
setInvalidated(true);
}
} else if(drawable instanceof TransitionDrawable) {
TransitionDrawable transitionDrawable = (TransitionDrawable) drawable;
// If last bitmap in chain is recycled, just blank this out since it would be invalid anyways
Drawable lastDrawable = transitionDrawable.getDrawable(transitionDrawable.getNumberOfLayers() - 1);
if(isBitmapRecycled(lastDrawable)) {
this.setImageDrawable(null);
setInvalidated(true);
} else {
// Go through earlier bitmaps and make sure that they are not recycled
for (int i = 0; i < transitionDrawable.getNumberOfLayers(); i++) {
Drawable layerDrawable = transitionDrawable.getDrawable(i);
if (isBitmapRecycled(layerDrawable)) {
// If anything in the chain is broken, just get rid of transition and go to last drawable
this.setImageDrawable(lastDrawable);
break;
}
}
}
