如何创建100％自定义对话框片段

Question

我想要使用完全自定义片段的Android对话框：没有包含平台对话框主题片段。例如，像这样：

我该怎么办呢？

Answer 1

以下用于Android C＃代码的Mono可以做到这一点（但应该很容易移植到Java）。我测试了Android 2.2（Galaxy S）和Android 4.1（Nexus 7）。唯一需要更改的是用于父视图和对话视图的布局ID。

[Activity (MainLauncher = true)]    
public class TestCustomDialogActivity : FragmentActivity 
{ 
    public class MyDialogFragment : Android.Support.V4.App.DialogFragment 
    { 
     public override Android.Views.View OnCreateView(Android.Views.LayoutInflater inflater, ViewGroup container, Bundle savedInstanceState) 
     { 
      // Android 3.x+ still wants to show title: disable 
      Dialog.Window.RequestFeature(WindowFeatures.NoTitle); 

      // CHANGE TO YOUR DIALOG LAYOUT or VIEW CREATION CODE 
      return inflater.Inflate(Resource.Layout.MyLayout, container, true); 
     } 

     public override void OnResume() 
     { 
      // Auto size the dialog based on it's contents 
      Dialog.Window.SetLayout(LinearLayout.LayoutParams.WrapContent, LinearLayout.LayoutParams.WrapContent); 

      // Make sure there is no background behind our view 
      Dialog.Window.SetBackgroundDrawable(new ColorDrawable(Color.Transparent)); 

      // Disable standard dialog styling/frame/theme: our custom view should create full UI 
      SetStyle(Android.Support.V4.App.DialogFragment.StyleNoFrame, Android.Resource.Style.Theme); 

      base.OnResume(); 
     } 
    } 

    protected override void OnCreate(Bundle bundle) 
    { 
     base.OnCreate(bundle); 

     // CHANGE TO YOUR MAIN SCREEN 
     SetContentView(Resource.Layout.MyDialog); 

     var dialog = new MyDialogFragment(); 
     dialog.Show(SupportFragmentManager, "dialog"); 
    }   
}

代码将帮助你全屏显示对话框，它还设置透明色

Dialog dialog = new Dialog(this); 
dialog.getWindow().requestFeature(Window.FEATURE_NO_TITLE); 
dialog.getWindow().setFlags(WindowManager.LayoutParams.FLAG_FULLSCREEN, WindowManager.LayoutParams.FLAG_FULLSCREEN); 
// layout to display 
dialog.setContentView(R.layout.about_program_dialog_layout); 

// set color transpartent 
dialog.getWindow().setBackgroundDrawable(new ColorDrawable(Color.TRANSPARENT)); 

dialog.show(); 

about_program_dialog_layout.xml

<?xml version="1.0" encoding="utf-8"?> 
<RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android" 
    android:layout_width="match_parent" 
    android:layout_height="match_parent" 
    android:orientation="vertical" 
    android:background="#55000000" > 

    <Button 
     android:id="@+id/button1" 
     android:layout_width="wrap_content"

     android:layout_alignParentBottom="true" 
     android:layout_centerHorizontal="true" 
     android:layout_marginBottom="227dp" 
     android:text="Dismiss" /> 

    <TextView

     android:layout_width="wrap_content" 
     android:layout_height="wrap_content"

     android:layout_alignParentRight="true" 
     android:layout_marginBottom="16dp"

</RelativeLayout>
