android viewpagerindicator多次调用getPageTitle（）
[英]android viewpagerindicator calling getPageTitle() too many times
问题描述
我正在使用viewpagerindicator作为我的android应用程序的一部分。 fragmentAdapter的getPageTitle在页面的每张幻灯片上被调用太多次。 我使用viewpagerindicator提供的示例应用程序对其进行了验证。
作为viewpagerindicator的一部分提供的示例应用程序只有4个片段/页面。 但是在每张幻灯片之后，每个位置的getPageTitle都会被调用近10到15次。 Logger语句随输出附在一起。
有什么办法可以避免这种情况？
@Override
public CharSequence getPageTitle(int position) {
Log.d("SAMPLE","Title Getting called for "+position);
return TestFragmentAdapter.CONTENT[position % CONTENT.length];
}

它按预期工作。 适配器始终总是提前两页加载（因此，它需要当前，上一页和下一页的标题）。 如果要避免这种行为，可以尝试在viewpager实例上调用setOffscreenPageLimit(0)
