Android/Java如何将线性布局添加到片段？

Question

我目前正在一个应用程序，但我需要帮助。我怎样才能把它放在你有清单的地方，当你按下一个项目时，它就会进入它的描述。一个例子可以在这个应用程序 https://play.google.com/store/apps/details?id=com.actionbarsherlock.sample.fragments&feature=more_from_developer#?t=W251bGwsMSwxLDEwMiwiY29tLmFjdGlvbmJhcnNoZXJsb2NrLnNhbXBsZS5mcmFnbWVudHMiXQ ..

我怎样才能得到你什么时候你按布局。

我有标签，但我无法获得列表。这是主要的活动代码。

public class MainActivity extends FragmentActivity implements ActionBar.TabListener { 

/** 
* The {@link android.support.v4.view.PagerAdapter} that will provide fragments for each of the 
* sections. We use a {@link android.support.v4.app.FragmentPagerAdapter} derivative, which will 
* keep every loaded fragment in memory. If this becomes too memory intensive, it may be best 
* to switch to a {@link android.support.v4.app.FragmentStatePagerAdapter}. 
*/ 
SectionsPagerAdapter mSectionsPagerAdapter; 

/** 
* The {@link ViewPager} that will host the section contents. 
*/ 
ViewPager mViewPager; 

@Override 
public void onCreate(Bundle savedInstanceState) { 
    super.onCreate(savedInstanceState); 
    setContentView(R.layout.activity_main); 
    // Create the adapter that will return a fragment for each of the three primary sections 
    // of the app. 
    mSectionsPagerAdapter = new SectionsPagerAdapter(getSupportFragmentManager()); 

    // Set up the action bar. 
    final ActionBar actionBar = getActionBar(); 
    actionBar.setNavigationMode(ActionBar.NAVIGATION_MODE_TABS); 

    // Set up the ViewPager with the sections adapter. 
    mViewPager = (ViewPager) findViewById(R.id.pager); 
    mViewPager.setAdapter(mSectionsPagerAdapter); 

    // When swiping between different sections, select the corresponding tab. 
    // We can also use ActionBar.Tab#select() to do this if we have a reference to the 
    // Tab. 
    mViewPager.setOnPageChangeListener(new ViewPager.SimpleOnPageChangeListener() { 
     @Override 
     public void onPageSelected(int position) { 
      actionBar.setSelectedNavigationItem(position); 
     } 
    }); 

    // For each of the sections in the app, add a tab to the action bar. 
    for (int i = 0; i < mSectionsPagerAdapter.getCount(); i++) { 
     // Create a tab with text corresponding to the page title defined by the adapter. 
     // Also specify this Activity object, which implements the TabListener interface, as the 
     // listener for when this tab is selected. 
     actionBar.addTab(
       actionBar.newTab() 
         .setText(mSectionsPagerAdapter.getPageTitle(i)) 
         .setTabListener(this)); 
    }

我认为你正在寻找一个开箱即用的解决方案。最近我不得不做同样的事情，我没有找到一个开箱即用的解决方案。我做了什么？我创建了一个带有alpha动画的不可见视图，当用户点击我的listview时，我开始动画并显示带有内容的填充视图。

还有其他方法可以通过创建自定义对话框并从xml文件中放大视图来实现此目的。

更简单的是，如果您不需要与描述视图进行交互，那么您可以使用带有修改视图的Toast并为用户设置时间来阅读。
