如何刪除對話框中的邊框

Question

此問題已被解答爲Dialog而我知道的不是DialogFrame。

我想刪除此圖片中顯示的邊框。 對不起，沒有圖片允許。

這是我的代碼：

public class SettingDialogFragment extends DialogFragment { 

    public SettingDialogFragment() { 
     // constructor 
    } 

    public Dialog onCreateDialog(Bundle savedInstanceState) { 
     ContextThemeWrapper context = new ContextThemeWrapper(getActivity(), 0); 

     context.setTheme(R.style.dialog); 

     AlertDialog.Builder alertDlgBldr = new AlertDialog.Builder(getActivity()); 

     LayoutInflater inflater = getActivity().getLayoutInflater(); 

     alertDlgBldr.setView(inflater.inflate(R.layout.dialog_theme, null)); 

     return alertDlgBldr.create(); 
    } 
} 

這是佈局：

<RelativeLayout 
    xmlns:android="http://schemas.android.com/apk/res/android" 
    android:layout_width="wrap_content" 
    android:layout_height="wrap_content"> 

    <TextView 
     android:id="@+id/dialog_title" 
     style="@style/title" 
     android:layout_width="wrap_content" 
     android:layout_height="wrap_content" 
     android:layout_alignParentLeft="true" 
     android:layout_alignParentTop="true" 
     android:layout_centerHorizontal="true" 
     android:text="@string/dialog_theme_title" 
     android:textAppearance="?android:attr/textAppearanceLarge" 
     android:textColor="@color/logo_color" 
     android:textStyle="bold" /> 

    <TextView 
     android:id="@+id/dialog_text" 
     style="@style/body" 
     android:layout_width="wrap_content" 
     android:layout_height="wrap_content" 
     android:layout_alignLeft="@id/dialog_text" 
     android:layout_below="@id/dialog_title" 
     android:text="Demonstation how to use vector drawables to style a dialog box" 
     android:textAppearance="?android:attr/textAppearanceSmall" 
     android:textColor="@color/logo_color" /> 

    <ImageView 
     android:id="@+id/dialog_image" 
     android:layout_width="150dp" 
     android:layout_height="150dp" 
     android:layout_below="@id/dialog_text" 
     android:layout_centerHorizontal="true" 
     android:src="@drawable/cats_dogs" /> 

</RelativeLayout> 

這是風格

<style 
    name="dialog"> 
    <!-- title encapsulating main part (backgroud) of custom alertdialog --> 
    <item 
     name="android:windowFrame">@null</item> 
     <!-- turn off any drawable used to draw a frame on the window --> 
    <item 
     name="android:windowBackground">@drawable/dialog_background</item> 
     <!-- turn off any drawable used to draw a frame on the window --> 
    <item 
     name="android:windowIsFloating">true</item> 
     <!-- float the window so it does not fill the screen --> 
    <item 
     name="android:windowNoTitle">true</item> 
     <!-- remove the title bar we make our own--> 
    <item 
     name="android:windowContentOverlay">@null</item> 
     <!-- remove the shadow from under the title bar --> 
</style> 

這個繪製

<shape 
    xmlns:android="http://schemas.android.com/apk/res/android" 
    android:shape="rectangle" > 
    <solid 
     android:color="#00000000"/> 
    <corners 
     android:radius="10dp"/> 
    <stroke 
     android:color="#FFF000" 
     android:width="3dp" /> 
</shape> 

我想我現在已經試過了這本書的每一招。搜索了三天的Stackoverflow現在，但大多數答案都與Dialog不是DialogFragment有關。 請幫我出來

這段代碼解決了這個問題，最後！

public class SettingDialogFragment extends DialogFragment { 

    public SettingDialogFragment() { 
     // this empty constructor without any parameter is required by Android 
     // to in order to instantiate the fragment when it needs to do so. 
    } 

    @Override 
    public void onCreate(Bundle savedInstanceState) { 
     super.onCreate(savedInstanceState); 
     setStyle(STYLE_NORMAL, android.R.style.Theme_Light_Panel); 
    } 

    @Override 
    public Dialog onCreateDialog(Bundle savedInstanceState) { 
     return super.onCreateDialog(savedInstanceState); 
    } 

    @Override 
    public View onCreateView(LayoutInflater inflater, ViewGroup container, 
      Bundle savedInstanceState) { 

     View view = inflater.inflate(R.layout.dialog_theme, container, false); 

     return view; 
    } 
}

這行代碼會幫助你

dialog.getWindow（）setBackgroundDrawable（新ColorDrawable（0））。

Answer 2

我用

public class EventAgeGateDialogFragment extends DialogFragment implements DatePicker.OnDateChangedListener { 

    @Override 
    public void onResume() 
    { 
     super.onResume();  
     getDialog().getWindow().setBackgroundDrawable(new ColorDrawable(Color.TRANSPARENT)); 
     setStyle(DialogFragment.STYLE_NO_FRAME, android.R.style.Theme); 
    } 

    @Override 
    public Dialog onCreateDialog(Bundle savedInstanceState) { 
     final Dialog dialog = super.onCreateDialog(savedInstanceState); 
     dialog.requestWindowFeature(DialogFragment.STYLE_NO_TITLE); 
     View view = View.inflate(getActivity(), R.layout.the_dialog_layout, null); 
     dialog.setContentView(view); 
     return dialog; 
    } 
}
