AlertDialog - 自定义视图和标题/按钮差距 [英] AlertDialog - gap between custom view and title/buttons

问题描述

我用一个AlertDialog自定义视图。在仿真器中，有一些空间上方和customeView下方。如果我设置了AlertDialog一个标题和按钮，我可以看到标题面板/按键面板和customView之间的差距。如何删除的差距？

I use a custom view for an AlertDialog. In the emulator, there is some space above and below the customeView. If I set a title and buttons for the AlertDialog, I can see the gap between the title panel/button panel and the customView. How can I remove the gap?

我的code打开AlertDialog：

My code to open the AlertDialog:

        btnShowDialog.Click += (object sender, EventArgs e) => 
        { 
            var customView = LayoutInflater.Inflate(Resource.Layout.myDialog, null); 
            var builder = new AlertDialog.Builder(this); 
            builder.SetTitle("Title"); 
            builder.SetView(customView); 

            builder.Create().Show(); 
        }; 

该customView布局：

The customView layout:

<?xml version="1.0" encoding="utf-8"?> 
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
    android:orientation="vertical" 
    android:layout_width="fill_parent" 
    android:layout_height="wrap_content" 
    android:background="#FFFFFF">
    <TextView 
        android:id="@+id/DialogText" 
        android:text="This is my custom view. Blur Blur Blur" 
        android:layout_marginLeft="10dp" 
        android:layout_marginRight="10dp" 
        android:layout_height="wrap_content" 
        android:layout_width="wrap_content" />
    <EditText 
        android:id="@+id/EnterPhone" 
        android:inputType="phone" 
        android:layout_width="fill_parent" 
        android:layout_height="wrap_content" 
        android:layout_marginLeft="10dp" 
        android:layout_marginRight="10dp" 
        android:hint="enter your number" />
</LinearLayout>

我已经测试AlertDialog中Android的4.0.3和4.1.2模拟器，并得到了同样的问题。

I have tested the AlertDialog in android 4.0.3 and 4.1.2 emulator and get the same issue.

感谢您的帮助！

推荐答案

而不是使用 AlertDialog 尝试使用对话框而不是像这样：

Instead of using AlertDialog try using Dialog instead like so:

var dialog = new Dialog(this);
dialog.SetTitle("Hey there");

dialog.SetContentView(Resource.Layout.myDialog);
dialog.Show();

这让我在底部无缝隙的对话框。

This gives me the a dialog with no gap in the bottom.

您也可以离开标题出来和自定义视图填满整个对话框。

You could also leave the title out and fill the entire Dialog with your custom view.

var dialog = new Dialog(this);
dialog.RequestWindowFeature((int)WindowFeatures.NoTitle);

dialog.SetContentView(Resource.Layout.myDialog);
dialog.Show();

和使用此布局：

<?xml version="1.0" encoding="utf-8"?>
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
    android:orientation="vertical"
    android:layout_width="fill_parent"
    android:layout_height="wrap_content"
    android:background="#FFFFFF">
    <LinearLayout
        android:layout_width="fill_parent"
        android:layout_height="wrap_content"
        android:background="#000000">
        <TextView
            android:text="Hey there"
            android:layout_width="fill_parent"
            android:layout_height="wrap_content"
            android:layout_margin="10dp"
            style="@android:style/TextAppearance.DialogWindowTitle" />
    </LinearLayout>
    <TextView
        android:id="@+id/DialogText"
        android:text="This is my custom view. Blur Blur Blur"
        android:layout_marginLeft="10dp"
        android:layout_marginRight="10dp"
        android:layout_height="wrap_content"
        android:layout_width="wrap_content" />
    <EditText
        android:id="@+id/EnterPhone"
        android:inputType="phone"
        android:layout_width="fill_parent"
        android:layout_height="wrap_content"
        android:layout_marginLeft="10dp"
        android:layout_marginRight="10dp"
        android:hint="enter your number" />
</LinearLayout>
