android - DialogFragment去除黑边

Question

我看到了this question还有this one和其他一些人，但没有任何真正帮助我。

我正在为我的 ListView 构建一个快速操作 DialogFragment 并尝试根据 android dev guide 为其设置自定义 View .

view_quick_action.xml

<?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;
    }
}

在所有这一切之后，当我运行 dialogFragment.show(getSupportedFragmentManager()) 时，我仍然得到如图所示的黑色边框:

关于如何解决这个问题有什么想法吗？

Answer 1

试试下面的代码:

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;
    }
}

在 res/value/style.xml 文件中添加 Dialog_No_Border 样式。

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

此样式导致 R 在清理后被删除
