问题描述

我试图让一个弹出窗口行为! =)



问题是弹出窗口填充整个屏幕的宽度,即使布局清楚地表示它应该是wrap_content。如果我使用Dialog或PopupWindow,这并不重要。



首先,弹出窗口的XML布局,popup_message.xml:

 <?xml version =1.0encoding =utf-8?> 
< LinearLayout xmlns:android =http://schemas.android.com/apk/res/android
android:layout_width =wrap_content
android:layout_height =match_parent
android:layout_margin =20dp
android:background =@ android:color / transparent
android:orientation =vertical>

< LinearLayout
android:layout_width =match_parent
android:layout_height =40dp
android:orientation =horizo​​ntal
android: layout_gravity =center>

< TextView
android:layout_width =match_parent
android:layout_height =fill_parent
android:layout_gravity =center
android: background =@ android:color / transparent
android:gravity =center_vertical | center_horizo​​ntal
android:orientation =horizo​​ntal
android:paddingLeft =10dp
android :text =@ string / new_message
android:textColor =#000000
android:textAllCaps =true>

< / TextView>
< / LinearLayout>

< RelativeLayout
android:layout_width =wrap_content
android:layout_height =wrap_content
android:padding =15dp
android: background =#ffffff
android:gravity =center_horizo​​ntal
android:orientation =vertical>

< TextView
android:id =@ + id / popup_message_textView
android:layout_width =wrap_content
android:layout_height =wrap_content
android:textAppearance =?android:attr / textAppearanceMedium
android:textCursorDrawable =@ null>
< / TextView>

< Button
android:id =@ + id / jobview_pickup_start_submit
android:layout_width =fill_parent
android:layout_height =35dp
android:layout_below =@ + id / popup_message_textView
android:layout_gravity =center_vertical | center_horizo​​ntal
android:layout_marginBottom =15dp
android:layout_marginTop =15dp
android:gravity =center_horizo​​ntal
android:text =Confirm
android:textColor =#000000/>
< / RelativeLayout>
< / LinearLayout>

我正在使用的代码:

  LayoutInflater inflater =(LayoutInflater)getSystemService(Context.LAYOUT_INFLATER_SERVICE); 
查看输入= inflater.inflate(R.layout.popup_message,null);
PopupWindow pw = new PopupWindow(input,LayoutParams.WRAP_CONTENT,LayoutParams.WRAP_CONTENT,true);
查看v = findViewById(R.id.main_deviceInfoBar);
pw.showAtLocation(v,Gravity.CENTER,0,0);

我也尝试过:



对话框dialogManualStart = new Dialog(MainActivity.this);
dialogManualStart.getWindow()。setBackgroundDrawableResource(R.color.transparent);
dialogManualStart.requestWindowFeature(MainActivity.this.getWindow()。FEATURE_NO_TITLE);
dialogManualStart.setContentView(input);
dialogManualStart.show();



总是,无论我使用什么代码,看起来像这样:





您可以看到,它总是填补屏幕的宽度。



问题:有谁可以告诉我为什么?



========编辑1 =============



我更改了按钮到wrap_content(根据Boogers的建议),然后看起来像这样:





这是非常奇怪的行为,而不是我的预期。



如果我将其更改为match_parent,则返回full width,即从左到右扩展。

解决方案

这是您的问题:

 < Button 
android:id =@ + id / jobview_pickup_start_submit
更改为fill_parent到wrap_content或match_parent


I am trying to get a popup to behave! =)

The problem is that the popup "fills the width" of the entire screen, even though the layout clearly says that it should "wrap_content". It doesnt matter if I use Dialog or PopupWindow.

First, the XML layout of the popup, popup_message.xml:

<?xml version="1.0" encoding="utf-8"?>
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
    android:layout_width="wrap_content"
    android:layout_height="match_parent"
    android:layout_margin="20dp"
    android:background="@android:color/transparent"
    android:orientation="vertical" >

    <LinearLayout
        android:layout_width="match_parent"
        android:layout_height="40dp"
        android:orientation="horizontal"
        android:layout_gravity="center" >

        <TextView
            android:layout_width="match_parent"
            android:layout_height="fill_parent"
            android:layout_gravity="center"
            android:background="@android:color/transparent"
            android:gravity="center_vertical|center_horizontal"
            android:orientation="horizontal"
            android:paddingLeft="10dp"
            android:text="@string/new_message"
            android:textColor="#000000"
            android:textAllCaps="true" >

        </TextView>
    </LinearLayout>

    <RelativeLayout
        android:layout_width="wrap_content"
        android:layout_height="wrap_content"
        android:padding="15dp"
        android:background="#ffffff"
        android:gravity="center_horizontal"
        android:orientation="vertical" >

        <TextView
            android:id="@+id/popup_message_textView"
            android:layout_width="wrap_content"
            android:layout_height="wrap_content"
            android:textAppearance="?android:attr/textAppearanceMedium"
            android:textCursorDrawable="@null" >
        </TextView>

        <Button
            android:id="@+id/jobview_pickup_start_submit"
            android:layout_width="fill_parent"
            android:layout_height="35dp"
            android:layout_below="@+id/popup_message_textView"
            android:layout_gravity="center_vertical|center_horizontal"
            android:layout_marginBottom="15dp"
            android:layout_marginTop="15dp"
            android:gravity="center_horizontal"
            android:text="Confirm"
            android:textColor="#000000" />
    </RelativeLayout>
</LinearLayout>

And the code I am using:

LayoutInflater inflater = (LayoutInflater)getSystemService(Context.LAYOUT_INFLATER_SERVICE);
View input = inflater.inflate(R.layout.popup_message, null);
PopupWindow pw = new PopupWindow(input, LayoutParams.WRAP_CONTENT, LayoutParams.WRAP_CONTENT, true);
View v = findViewById(R.id.main_deviceInfoBar);
pw.showAtLocation(v, Gravity.CENTER, 0, 0);

I have also tried this:

Dialog dialogManualStart = new Dialog(MainActivity.this);dialogManualStart.getWindow().setBackgroundDrawableResource(R.color.transparent);dialogManualStart.requestWindowFeature(MainActivity.this.getWindow().FEATURE_NO_TITLE);dialogManualStart.setContentView(input);dialogManualStart.show();

And it always, no matter what code I use, looks like this:

As you can see, its always filling the width of the screen.

Question: Can anyone tell me why?

======== EDIT 1 =============

I changed the Button to "wrap_content" (according to Boogers suggestion), and then it looks like this:

This is very strange behaviour, not what I expected.

If I change it to "match_parent", its back to "full width", ie it extends all the way from left to right.

解决方案

This is your problem:

<Button
            android:id="@+id/jobview_pickup_start_submit"
            android:layout_width="fill_parent"
...

Change that from "fill_parent" to "wrap_content" or "match_parent"
