我已经使用 this 创建了我的项目 Material 设计示例。我已经修改了代码，现在我有 5 个标签。现在我已经创建了 5 个 fragment 类并将其加载到 View 寻呼机上。现在我想要的是，我想将选定的滑动菜单位置作为参数传递给我正在加载的 fragment 。这里的问题是，我可以将参数(使用 Bundle)传递给 FragmentPagerAdapter ，但它不会根据我传递的参数重新加载 fragment !问题是它甚至没有在 FragmentPagerAdapter 中执行页面加载部分!
我如何根据我传递的参数在 Taps 上重新加载我的 fragment ？ 仅供引用，根据我传递的参数值，我正在做一些处理，我想在选项卡上显示处理过的 fragment 页面。
请帮助这是我现在面临的系列问题! 提前致谢:)
这是我的适配器代码
public class ViewPagerAdapter1 extends FragmentPagerAdapter {
final int PAGE_COUNT =6;
private String titles[] ;
Bundle b2;
public ViewPagerAdapter1(FragmentManager fm, String[] titles2, Bundle b) {
super(fm);
titles=titles2;
this.b2=b;
}
@Override
public Fragment getItem(int position) {
switch (position) {
case 0:
return new GridTableActivity();
case 1:
Bundle selected1 = new Bundle();
selected1.putInt("selected",0);
GridTableActivity gridTableActivity = new GridTableActivity();
gridTableActivity.setArguments(selected1);
return gridTableActivity;
case 2:
Bundle selected2 = new Bundle();
selected2.putInt("selected",0);
DownTimeTable downTimeTable = new DownTimeTable();
downTimeTable.setArguments(selected2);
return downTimeTable;
case 3:
Bundle selected3 = new Bundle();
selected3.putInt("selected",0);
GraphActivity graphActivity = new GraphActivity();
graphActivity.setArguments(selected3);
return graphActivity;
case 4:
Bundle selected4 = new Bundle();
selected4.putInt("selected",0);
BarChartActivity barChartActivity = new BarChartActivity();
barChartActivity.setArguments(selected4);
return barChartActivity;
case 5:
Bundle selected5 = new Bundle();
selected5.putInt("selected",0);
PieChartActivity pieChartActivity = new PieChartActivity();
pieChartActivity.setArguments(selected5);
return pieChartActivity;
}
return null;
}
public CharSequence getPageTitle(int position) {
return titles[position];
}
@Override
public int getCount() {
return PAGE_COUNT;
}}
目前我正在这样做!我的抽屉里有 9 件元素，并创建了 9 个不同的适配器类!(这真让人难过!:|)

最佳答案
我想通了!一个简单的解决方案浪费了很多时间!我应该使用 FragmentStatePagerAdapter 而不是 FragmentPagerAdapter!!!呜呜呜! :/
关于android - FragmentPagerAdapter 根据参数值重新加载选项卡上处理过的 fragment ，我们在Stack Overflow上找到一个类似的问题： https://stackoverflow.com/questions/30885610/
