弹出窗口（使用PopupWindow或Dialog）填满屏幕的宽度无缘无故 [英] Popup (using PopupWindow or Dialog) fills the width of the screen for no apparent reason

问题描述

我想，弹出的行为！ =）

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

问题是，在弹出的填充宽度整个屏幕，即使布局清楚地说，它应该WRAP_CONTENT。如果我使用对话框或PopupWindow这并不重要。

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.

首先，在弹出的XML布局，popup_message.xml：

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>

而code我使用的：

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);

我也试过这样的：

I have also tried this:

对话框dialogManualStart =新的对话框（MainActivity.this）;
。dialogManualStart.getWindow（）setBackgroundDrawableResource（R.color.transparent）;
dialogManualStart.requestWindowFeature（MainActivity.this.getWindow（）FEATURE_NO_TITLE）;
dialogManualStart.setContentView（输入）;
dialogManualStart.show（）;

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();

和它总是，无论什么code我用，看起来是这样的：

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

正如你所看到的，它总是填充屏幕的宽度。

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

问：谁能告诉我，为什么

我改成WRAP_CONTENT（据鼻屎建议）按钮，然后它看起来像这样：

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

这是很奇怪的行为，不出我所料。

This is very strange behaviour, not what I expected.

如果我把它改为match_parent，将其带回全宽，由左到右，即它扩展的所有道路。

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

推荐答案

这是你的问题：

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

更改，从FILL_PARENT到WRAP_CONTENT或match_parent

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