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 =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>
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。
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"
