我想在短時間內同時更改多個文字瀏覽(> 30)。但如果這些步驟很短(< 100毫秒),則變化非常緩慢。我想實現~10ms。即時通訊調試聯繫4.是行爲正常嗎? 繼承人我的代碼:Android更改多個UI元素
public class AsyncChangeUI extends AsyncTask<Void, Integer, Void> {
View view;
int oldPercentage;
int newPercentage;
AsyncChangeUI(View view, int oldPercentage, int newPercentage){
super();
this.view = view;
this.oldPercentage = oldPercentage;
this.newPercentage = newPercentage;
}
@Override
protected Void doInBackground(Void... params) {
Log.e("Kachel", view.getClass().getName());
for(Integer i=this.oldPercentage; i<=newPercentage; i++){
this.oldPercentage = i;
try {
Thread.sleep(10); //laggy if <100
publishProgress(i);
}catch(InterruptedException e) {
e.printStackTrace();
}
}
return null;
}
@Override
protected void onProgressUpdate(Integer... progress) {
List<TileGroupLayout> tileGroupList = ((MainLinearLayout) view).tileGroupList;
for (TileGroupLayout tileGroup: tileGroupList) {
List<TileLayout> tileList = tileGroup.tileList;
for (TileLayout tile: tileList) {
tile.changePercentageTo(progress[0]);
}
}
}
}
thx! 我注意到改變的最後步驟比第一步更遲緩:S

是的,沒有任何影響。你知道這個影響有多強大嗎? – user2304753 2013-04-21 16:23:52
