我看到了this question以及this one和其他一些人,但没有任何帮助我。

我正在为列表视图构建快速操作DialogFragment,并尝试根据android dev guide设置自定义视图。

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;
    }
}

毕竟,当我运行dialogFragment.show(getSupportedFragmentManager())时,我仍然会看到图像中所示的黑色边框: quickActionImage

关于如何解决此问题的任何想法?

尝试以下代码:

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;
    }
}

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

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

此样式会导致在清除

在创建实例时尝试使用setStyle(style,theme)方法,如下所示:

public static YourDialog newInstance() {
    YourDialog frag = new YourDialog();
    // your code
    frag.setStyle(DialogFragment.STYLE_NO_FRAME, 0);
    // your code
    return frag;
}

我希望这有帮助。

答案 2 :(得分:0)

由于顶部和底部都被截断,我无法获得任何姜饼工作的答案,但我找到了一个解决方法:您可以在顶部和底部设置额外的填充以抵消切割 - 关闭。

if(Build.VERSION.SDK_INT < Build.VERSION_CODES.HONEYCOMB) {
    int padding = getResources().getDimensionPixelSize(R.dimen.your_padding);
    view.setPadding(0, padding, 0, padding);
}

然后按照其他答案的规定设置视图

demoDialog.setView(view, 0, 0, 0, 0);

答案 3 :(得分:0)

我无法在Xamarin上获得任何这些工作 - Android。也许这个解决方案可以为那里的人节省一些时间:

public override void OnCreate(Bundle savedInstanceState)
{
    base.OnCreate(savedInstanceState);
    SetStyle(DialogFragmentStyle.NoFrame, 0);
}

public override void OnResume()
{
    base.OnResume();
    Dialog.Window.SetBackgroundDrawableResource(Resource.Color.transparent);
}

如果资源中没有“透明”颜色,您可以创建它或使用Android中的默认颜色。我在定制MvvmCross Fingerprint Plugin的对话框片段时遇到了这个问题。
