示例1: display

public <T extends View> void display(T container, String uri, BitmapDisplayConfig displayConfig, BitmapLoadCallBack<T> callBack) {
if (container == null) {
return;
}

callBack = new DefaultBitmapLoadCallBack<T>(); //默认的回调
}
if (displayConfig == null || displayConfig == defaultDisplayConfig) {
displayConfig = defaultDisplayConfig.cloneNew();// 默认展示图片的设置
}
// Optimize Max Size
BitmapSize size = displayConfig.getBitmapMaxSize();
//配置显示控件的大小
displayConfig.setBitmapMaxSize(BitmapCommonUtils.optimizeMaxSizeByView(container, size.getWidth(), size.getHeight()));
container.clearAnimation();
if (TextUtils.isEmpty(uri)) {
callBack.onLoadFailed(container, uri, displayConfig.getLoadFailedDrawable());
return;
}
// start loading

// find bitmap from mem cache. 优先从运行内存的缓存中读取
