Android 对话框宽度

问题描述

我似乎无法控制对话框宽度.我有一个像这样的简单布局`

I can't seem to control the dialog width. I have a simple layout like so`

<?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="fill_parent"
    android:theme="@android:style/Theme.Dialog"> 

    <ScrollView 
        android:orientation="vertical"
        android:layout_width="fill_parent"
        android:layout_height="fill_parent">
        <LinearLayout     android:orientation="vertical"
        android:layout_width="fill_parent"
        android:layout_height="fill_parent">

        <TextView 
            android:id="@+id/name_prompt_view"
            android:layout_width="fill_parent"
            android:layout_height="wrap_content"
            android:text="@string/name_prompt"
            android:padding="10dip"/>

        <EditText 
            android:id="@+id/name_inp" 
            android:layout_width="fill_parent" 
            android:layout_height="wrap_content" 
            android:lines="1"
            android:maxLines="1"
            android:maxLength="48"
            android:inputType="text" />

        <TextView 
            android:id="@+id/t1_prompt_view"
            android:layout_width="fill_parent"
            android:layout_height="wrap_content"
            android:text="@string/t1_prompt"
            android:padding="10dip"/>

        <Spinner 
            android:id="@+id/t1_inp" 
            android:layout_width="fill_parent" 
            android:layout_height="wrap_content" 
            android:lines="1"
            android:maxLines="1"
            android:maxLength="48"
            android:inputType="text"
            android:singleLine="true"
            android:layout_weight="1"
            android:entries= "@array/t1_allowed_values" />

         </LinearLayout>

    </ScrollView>

</LinearLayout>

由于某种原因，对话框的宽度仅足以容纳大约 11 个字符宽的文本输入字段.如何让对话框的宽度填满屏幕?

for some reason the dialog is only wide enough for the text input field about 11 chars wide. How do I make the dialog width fill the screen?

推荐答案

我也遇到了同样的问题.

I had the same problem.

我使用以下代码制作了对话框 fill_parent 并且效果很好.

I used following code to make dialog fill_parent and it worked fine.

public class SharePost extends Dialog
{
    @Override
    public void onCreate(Bundle savedInstanceState)
    {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.adaptor_contentsharepost);

        LayoutParams params = getWindow().getAttributes();
        params.height = LayoutParams.FILL_PARENT;
        getWindow().setAttributes((android.view.WindowManager.LayoutParams) params);
    }
}

布局

<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
    android:orientation="vertical"
    android:id="@+id/dialogWidth"
    android:layout_width="match_parent"
    android:layout_height="match_parent">
