问题描述
限制 onQueryTextChange
的最佳方法是什么,以便我的 performSearch()
方法每次只调用一次第二次而不是每次用户输入?
What's the best way to "throttle" onQueryTextChange
so that my performSearch()
method is called only once every second instead of every time the user types?
public boolean onQueryTextChange(final String newText) {
if (newText.length() > 3) {
// throttle to call performSearch once every second
performSearch(nextText);
}
return false;
}
推荐答案
我最终得到了一个解决方案类似于下面。这样它应该每半秒触发一次。
I ended up with a solution similar to below. That way it should fire once every half second.
public boolean onQueryTextChange(final String newText) {
if (newText.length() > 3) {
if (canRun) {
canRun = false;
handler.postDelayed(new Runnable() {
@Override
public void run() {
canRun = true;
handleLocationSearch(newText);
}
}, 500);
}
}
return false;
}
