如何显示全屏图像视图onlclick

Question

我相当新的xamarin.android，我有一个滚动视图中的图像视图，我想单击放大它。 （在手机脸书上显示完整图像onclick），当用户点击图像时，我希望它在全屏中打开。我该如何实现？

我做了一些研究，找不到一些有用的线程..任何帮助将appriciated谢谢你提前。

我的继承人detailactivity类

private ImageView mtimg0, mtimg1, mtimg2, mtimg3, mtimg4, mtimg5; 
protected override void OnCreate(Bundle savedInstanceState) 
{ 
     base.OnCreate(savedInstanceState); 
     SetContentView(Resource.Layout.detailLayout); 

     FindViews(); 


     Android.Content.Intent i = this.Intent; 
     string iname = i.Extras.GetString("MTNAME"); 
     int iimg0 = i.Extras.GetInt("IMG0"); 
     int iimg1 = i.Extras.GetInt("IMG1"); 
     int iimg2 = i.Extras.GetInt("IMG2"); 
     int iimg3 = i.Extras.GetInt("IMG3"); 
     int iimg4 = i.Extras.GetInt("IMG4"); 
     int iimg5 = i.Extras.GetInt("IMG5"); 

     mtimg0.SetImageResource(iimg0); 
     mtimg1.SetImageResource(iimg1); 
     mtimg2.SetImageResource(iimg2); 
     mtimg3.SetImageResource(iimg3); 
     mtimg4.SetImageResource(iimg4); 
     mtimg5.SetImageResource(iimg5); 
    } 

    private void FindViews() 
    { 
     tmtname = FindViewById<TextView>(Resource.Id.mtname); 
     mtimg0 = FindViewById<ImageView>(Resource.Id.mtimg00); 
     mtimg1 = FindViewById<ImageView>(Resource.Id.mtimg01); 
     mtimg2 = FindViewById<ImageView>(Resource.Id.mtimg02); 
     mtimg3 = FindViewById<ImageView>(Resource.Id.mtimg03); 
     mtimg4 = FindViewById<ImageView>(Resource.Id.mtimg04); 
     mtimg5 = FindViewById<ImageView>Resource.Id.mtimg05);    

    } 
} 

EDITED

这里是我的列表视图在那里我取得我的所有图片

class MountainsData 
    { 
    public static List<Mountain> MountainList = new List<Mountain>() 
     { 
     new Mountain() 
      { 
       MtName = "ALTO PEAK", 
       Masl = 1332, 
       Difficulty = 6, 
       Island = 2, 
       MtImg00 = Resource.Drawable.altopeak, 
       MtImg01 = Resource.Drawable.altopeak1, 
       MtImg02 = Resource.Drawable.altopeak2, 
       MtImg03 = Resource.Drawable.altopeak3, 
       MtImg04 = Resource.Drawable.altopeak4, 
       Location = "ORMOC, LEYTE", 
       JumpOff ="Lake Danao National Park, Ormoc", 
       Description ="LLA: 11.1061 N, 124.7097 E, 1332 
      } 

，并在项目的例子我列表视图活动..这里是我如何将每个项目传递给我的详细活动...并在我的详细活动中接收它我正在使用代码abo VE（在detailactivity类。在这个问题上面的第一个代码）

​​

什么，我想里面detailactivity发生的是，当我点击的ImageView ..在全屏幕显示，但我不能找到一种方法，正确地传递字符串..预先感谢您：d

这是一个DialogFragment解决方案：

你fragment_dialog.axml

<?xml version="1.0" encoding="utf-8"?> 
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android" 
    android:layout_width="match_parent" 
    android:layout_height="match_parent" 
    android:minWidth="2000dp" 
    android:minHeight="2000dp"> 
    <ImageView 
     android:layout_width="fill_parent" 
     android:layout_height="fill_parent" 
     android:id="@+id/img" 
     android:src="@drawable/aaa" 
     android:scaleType="fitCenter"/> 
</LinearLayout> 

个

你MyDialogFragment.cs

public class MyDialogFragment : DialogFragment 
{ 
    private ImageView imgView; 
    static public MyDialogFragment newInstance() 
    { 
     MyDialogFragment f = new MyDialogFragment(); 
     return f; 
    } 

    public override void OnCreate(Bundle savedInstanceState) 
    { 
     base.OnCreate(savedInstanceState); 
     SetStyle(DialogFragmentStyle.NoTitle, Android.Resource.Style.ThemeBlackNoTitleBarFullScreen); 
    } 

    public override View OnCreateView(LayoutInflater inflater, ViewGroup container, Bundle savedInstanceState) 
    { 
     base.OnCreateView(inflater, container, savedInstanceState); 
     View v = inflater.Inflate(Resource.Layout.fragment_dialog, container, false); 

     imgView = v.FindViewById<ImageView>(Resource.Id.img); 
     //Get int and set it to the ImageView 
     int imgPassed = Arguments.GetInt("imgId"); 
     imgView.SetImageResource(imgPassed); 

     return v; 
    } 
} 

从您的ItemSelected或点击事件

 FragmentTransaction ft = FragmentManager.BeginTransaction(); 
     DialogFragment newFragment = MyDialogFragment.newInstance(); 

     //Declare String and get the Id 
     string imgName = "bbb"; //Change with the name of the image you want to pass 
     int imgId = Resources.GetIdentifier(imgName, "drawable", PackageName); 

     //Pass it with the Bundle class 
     Bundle bundle = new Bundle(); 
     bundle.PutInt("imgId", imgId); 
     newFragment.Arguments = bundle; 

     //Show the Fragment 
     newFragment.Show(ft, "dialog"); 

编辑： 我用捆绑类为可能的方式，从通过一个数据活动的碎片。对我来说工作得很好。

另一种方法具有相同的结果只是被使用另一个活动和意图，你可以找到你需要的一切在这里：Passing Data Between Activities
