ImageView的（QUOT; headbar＆QUOT;）不同的屏幕等 [英] ImageView ("headbar") different screens etc

问题描述

我只想做一个ImageView的作为我headbar ...它应该只是填写他的父母线性布局..显然事实并非如此。

I just want to make an ImageView as my headbar ... it should just fill out his parent linear-layout.. apparently it does not.

有没有办法告诉scaleType只是为了满足其母公司布局？ （XML中的最佳解决方案）我看到的是一个程序，解决方案，设置scaleType补......但似乎没有匹配的XML属性，还是没有我看看吗？

is there any way to tell the scaleType just to fit its parent-layout? (best solution in XML) i saw the was a programming-solution which setting the scaleType to "fill" ... but there seems to be no matching xml-attribute, or didn't i see it?

<?xml version="1.0" encoding="utf-8"?>
<RelativeLayout
  xmlns:android="http://schemas.android.com/apk/res/android"
  android:layout_width="fill_parent"
  android:layout_height="wrap_content">
    <LinearLayout
        android:layout_height="wrap_content"
        android:layout_width="fill_parent"
        android:layout_weight="1"
        android:id="@+id/linearlayoutmain">
    <ImageView
         android:layout_marginTop="0dp" 
         android:src="@drawable/headbar" 
         android:id="@+id/mainheadbar" 
         android:scaleType="fitStart"
         android:paddingTop="0dp"
         android:layout_height="fill_parent" 
         android:layout_width="fill_parent" 
        />
    </LinearLayout>
    <LinearLayout 
        android:layout_height="fill_parent"
        android:layout_width="fill_parent"
        android:layout_weight="7"
        android:layout_below="@id/linearlayoutmain">
    </LinearLayout>
</RelativeLayout>

有关它的任何想法/解决方案？我想我不必介意宽高比，因为我9patched整个事情..所以应该不会介意。

any thoughts/solutions about it? I thought i don't need to mind about the aspect ratio because I 9patched the whole thing.. so it shouldn't mind.

编辑：这似乎更好地工作时，我使用的ImageButton代替的ImageView的...但是，我得到了较低-size屏幕的问题......他们似乎不介意我9patching ...笑

edit: it seems to work better when i use an ImageBUtton instead of an imageview... however, i got problems on lower -size screens... they seem to don't mind my 9patching... lol

推荐答案

您需要在一般使用三种类型的布局

You need to use three types of layouts in general

1. 布局华电国际

1. layout-hdpi

布局于mdpi

布局LDPI

此外，你需要使用一般三个值的布局

Also you need to use three values layouts in general

1. 值，华电国际

1. values-hdpi

价值观MDPI

价值观LDPI

下面我为LDPI设备标题说明你有做你的设备华电国际，MDPI等

Here i explain for LDPI Device Header you have to do for all you device HDPI,MDPI, etc

例如简单的XML有图片为头：布局LDPI - 标题

For example simple xml that has Image as Header : layout-ldpi - Header

<?xml version="1.0" encoding="UTF-8"?>
  <RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android" 
            android:layout_width="fill_parent"  android:layout_height="50px"
            android:orientation="horizontal" >

  <ImageView    android:id="@+id/header_main_title" android:layout_marginTop="10dip"
                android:layout_width="wrap_content" android:layout_height="50dip" 
                android:background="@drawable/header_image" 
                android:layout_centerHorizontal="true" android:layout_marginRight="10dip" 
                 />

同样价值观LDPI包含

Similarly values-ldpi contains

<?xml version="1.0" encoding="utf-8"?>

  <resources>
     <style name="MyTheme" parent="android:Theme">
        <item name="android:windowTitleSize">50px</item>
      <item name="android:windowTitleBackgroundStyle">@style/WindowTitleBackground
       </item>      
     </style>
   </resources>

同样，对于Styles.xml：

Similarly for Styles.xml :

<?xml version="1.0" encoding="UTF-8"?>
<resources>
<style name="WindowTitleBackground" parent="android:WindowTitleBackground">
    <item name="android:background">@android:color/transparent</item>
</style>

在您的Manifest.xml包括此行：

In your Manifest.xml include this Line :

<application android:icon="@drawable/vmi_icon" android:label="@string/app_name"  android:theme="@style/MyTheme" >

把Styles.xml和的themes.xml里面的价值观LDPI 文件夹

我标题所示为LDPI设备同样需要创建 MDPI 和华电国际设备

I shown Header for ldpi device similarly you need to create for MDPI and HDPI device

改变应该在这条线全部进行

changes should be made in this line of all

如果这是华电国际：

<item name="android:windowTitleSize">100px</item>

如果是MDPI：

<item name="android:windowTitleSize">70px</item>

同样，对于header.xml：

Similarly for header.xml :

如果这是华电国际：

android:layout_height="100px"

如果是MDPI：

android:layout_height="70px"

让我知道如果你需要进一步澄清。
