示例1: doInBackground
import com.lidroid.xutils.bitmap.callback.BitmapLoadFrom; //导入依赖的package包/类
@Override
protected Bitmap doInBackground(Object... params) {
synchronized (pauseTaskLock) {
while (pauseTask && !this.isCancelled()) {
try {
pauseTaskLock.wait(); //将锁释放， 让其他Bitmap任务也进来。 当暂停且没有销毁的的时候就是一个死循环
if (cancelAllTask) {
return null;
}
} catch (Throwable e) {
}
}
}
Bitmap bitmap = null;
// get cache from disk cache
if (!this.isCancelled() && this.getTargetContainer() != null) {
this.publishProgress(PROGRESS_LOAD_STARTED);
//这里是优先从闪存内存中读取
bitmap = globalConfig.getBitmapCache().getBitmapFromDiskCache(uri, displayConfig);
//from 默认是BitmapLoadFrom.DISK_CACHE， 所以这里不需要设置
}
// download image
if (bitmap == null && !this.isCancelled() && this.getTargetContainer() != null) {
//开启下载任务
bitmap = globalConfig.getBitmapCache().downloadBitmap(uri, displayConfig, this);
from = BitmapLoadFrom.URI;
}
return bitmap;
