I saw this question and also this one and some others, but nothing really helped me.

我建立一个快速的行动 DialogFragment 我的列表视图，并试图根据的 Android开发人员指南。

I'm building a quick action DialogFragment for my list view and trying to set a custom view to it according to the android dev guide.

<?xml version="1.0" encoding="utf-8"?>
<RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android"
    android:layout_width="wrap_content"
    android:layout_height="wrap_content"
    android:background="@android:color/white" >

    <ImageView
        android:id="@+id/quick_action_image"
        android:layout_width="50dp"
        android:layout_height="50dp"
        android:layout_margin="20dp"
        android:scaleType="fitXY"
        android:src="@drawable/windows1" />

    <TextView
        android:id="@+id/quick_action_name"
        android:layout_width="wrap_content"
        android:layout_height="wrap_content"
        android:layout_alignTop="@+id/quick_action_image"
        android:layout_toRightOf="@+id/quick_action_image"
        android:ellipsize="end"
        android:singleLine="true"
        android:text="Lilly"
        android:textColor="#585858"
        android:textSize="16sp" />

    <TextView
        android:id="@+id/quick_action_activity"
        android:layout_width="wrap_content"
        android:layout_height="wrap_content"
        android:layout_alignBottom="@+id/quick_action_image"
        android:layout_toRightOf="@+id/quick_action_image"
        android:text="Updated 4 minutes ago"
        android:textColor="#a3a3a3"
        android:textSize="15sp" />

    <ImageButton
        android:id="@+id/popup_grid_leave"
        android:layout_width="50dp"
        android:layout_height="50dp"
        android:layout_alignParentLeft="true"
        android:layout_below="@+id/quick_action_activity"
        android:layout_margin="20dp"
        android:layout_marginTop="30dp"
        android:background="@color/transperent"
        android:src="@drawable/ic_action_leave" />

    <ImageButton
        android:id="@+id/popup_grid_silence"
        android:layout_width="50dp"
        android:layout_height="50dp"
        android:layout_alignBottom="@+id/popup_grid_leave"
        android:layout_alignTop="@+id/popup_grid_leave"
        android:layout_centerHorizontal="true"
        android:background="@color/transperent"
        android:src="@drawable/ic_action_silence" />

    <ImageButton
        android:id="@+id/popup_grid_mark_as_read"
        android:layout_width="50dp"
        android:layout_height="50dp"
        android:layout_alignBottom="@+id/popup_grid_leave"
        android:layout_alignParentRight="true"
        android:layout_alignTop="@+id/popup_grid_leave"
        android:layout_marginRight="15dp"
        android:background="@color/transperent"
        android:src="@drawable/ic_action_mark_as_read" />

</RelativeLayout>

QuickActionFragment.java

public class QuickActionFragment extends DialogFragment {

    @Override
    public Dialog onCreateDialog(Bundle savedInstanceState) {
    AlertDialog.Builder builder = new AlertDialog.Builder(mContext);

        View v = LayoutInflater.from(mContext).inflate(
        R.layout.view_quick_action, null, false);

        // SET ALL THE VIEWS

        builder.setTitle(null);

        AlertDialog dialog = builder.create();
        dialog.setView(v, 0, 0, 0, 0);
        // this line didn't change anything
        // dialog.getWindow().setBackgroundDrawable(new ColorDrawable(0));

        return dialog;
    }
}

这一切后，当我运行 dialogFragment.show（getSupportedFragmentManager（））我仍然得到的图像中显示的黑色边框：

after all this, when I run dialogFragment.show(getSupportedFragmentManager()) I still get the black border as shown in the image:

这是如何解决这一问题的任何想法？

any thoughts on how to fix this?

推荐答案

尝试下面code：

public class QuickActionFragment extends DialogFragment {

    @Override
    public Dialog onCreateDialog(Bundle savedInstanceState) {
        Dialog m_dialog = new Dialog(QuickActionFragment.this, R.style.Dialog_No_Border);
        LayoutInflater m_inflater = LayoutInflater.from(CustomDialogActivity.this);
        View v = LayoutInflater.from(mContext).inflate(R.layout.view_quick_action, null, false);
        // SET ALL THE VIEWS
        m_dialog.setTitle(null);
        m_dialog.setContentView(m_view);
        m_dialog.show();
        return dialog;
    }
}

添加 Dialog_No_Border 的风格在你的 RES /价值/ style.xml 文件。

<style name="Dialog_No_Border">
    <item name="android:windowIsFloating">true</item>
    <item name="android:windowBackground">@android:color/transparent</item>
</style>

此风格的原因研究来干净后删除

This style causes R to be deleted after a clean
