Android防止按钮连续点击

public class Utils {
private static long lastClickTime;
public synchronized static boolean isFastClick() {
long time = System.currentTimeMillis();
if ( time - lastClickTime < 500) {
return true;
}
lastClickTime = time;
return false;
}
}

按钮点击时，增加判断就行了：@Override
public void onClick(View v) {
if (Utils.isFastClick()) {
return ;
}
}
