安卓开发之使用Acache类对数据进行二级缓存(内存+文件)

public class MainActivity extends Activity {
private ImageView img;
Acache acache;
 
@Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);
acache = Acache.get(this, "main");
img = (ImageView) findViewById(R.id.img);
 
if (acache.getAsBitmap("pic") != null) {
Log.e("acache","正在使用缓存!");
img.setImageBitmap(acache.getAsBitmap("pic"));
} else {
Picasso.with(this).load("http://www.b.hsgjxt.com/image/cache/data/0-100x100.jpg").into(new Target() {
@Override
public void onBitmapLoaded(Bitmap bitmap, Picasso.LoadedFrom from) {
Log.e("Picasso","正在使用Picasso!");
img.setImageBitmap(bitmap);
acache.put("pic", bitmap, 10);
}
 
@Override
public void onBitmapFailed(Drawable errorDrawable) {
 
}
 
@Override
public void onPrepareLoad(Drawable placeHolderDrawable) {
 
}
});
}
 
}
}
