FragmentPagerAdapter重装基于参数值选项卡上的处理片段 [英] FragmentPagerAdapter reload the processed fragment on the tabs based on the parameter value
本文介绍了FragmentPagerAdapter重装基于参数值选项卡上的处理片段的处理方法，对大家解决问题具有一定的参考价值，需要的朋友们下面随着小编来一起学习吧！
问题描述
我一直在使用这的材料设计实例创建我的项目。我已经修改了code，现在我现在有5个选项卡。现在我已经创建了5片段类和加载它在视图寻呼机。现在我想的是，我想通过所选择的滑动菜单位置作为参数传递给它我加载的片段。这里的问题是，我可以（用捆绑）到FragmentPagerAdapter传递参数，但基于即时传递参数它不重装碎片！事情是它甚至没有执行在FragmentPagerAdapter网页加载的一部分！
i have created my project using this material design example. i have modified the code and now i have 5 tabs now. And now i have created 5 fragment classes and loading it on the view pager. now what i want is, i want to pass the selected sliding menu position as a parameter to the fragment which i am loading. Here the problem is, i can pass the parameter(using Bundle) to the FragmentPagerAdapter , but it is not reloading the fragments based on the parameter i'm passing! the thing is it is not even executing the page loading part in FragmentPagerAdapter!
我怎样才能重新加载基于即时传递参数我对丝锥片段？
仅供参考，以我是路过的，我做了一些处理的参数值，我想显示选项卡上的处理片段页面。
How can i reload my fragments on the Taps based on the parameter i'm passing? FYI, based on the parameter value that i'm passing, i'm doing some processing and i want to show the processed fragment page on the tabs.
请大家帮忙，这是该系列的问题我面对它现在！
在此先感谢：）
please help this is the series problem i'm facing it right now! Thanks in advance :)
下面是我的适配器code
Here is my adapter code
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;
}}
目前我做这个样子！我在抽屉里放及9项;创建9种不同的适配器类！（这么伤心SRY生根粉这一点：|！）
currently i'm doing like this! i have 9 items on the drawer & created 9 different adapter classes!(so sad sry abt this! :|)

推荐答案
我想通了！浪费了很多时间，一个简单的解决方案！我应该使用FragmentStatePagerAdapter FragmentPagerAdapter的！ uufff！ ：/
i figured out! wasted a lot of time for a simple solution! I should use FragmentStatePagerAdapter instead of FragmentPagerAdapter!!! uufff! :/
