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。我使用作为 viewpagerindicator 的一部分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，每个位置都会调用 getPageTitle 几乎 10 到 15 次。记录器语句附有输出。
有没有办法避免这种情况？
@Override
public CharSequence getPageTitle(int position) {
Log.d("SAMPLE","Title Getting called for "+position);
return TestFragmentAdapter.CONTENT[position % CONTENT.length];
}
