我的弹出式imageview中的问题 [英] problem in my popup imageview
问题描述
嗨
在我的项目中，如果用户点击一个图标，它将显示一个带滚动功能的弹出式图像视图。
我的问题是的，流行的图像应该是高分辨率，它应该可以调整所有类型的Android屏幕分辨率。
当用户点击图标时，图像应该是可调整的根据他们的模型或屏幕尺寸来推荐..
我的xml代码 -

android：layout_height =wrap_content

亲切指南我...
在此先感谢..
Hi
In my project if the user clicks an icon , it will display a popup imageview with scrolling function.
my problem is, the pop image should be high resolution, and it should be adjustable for all type of android screen resolution.
when user clicks the icon , the image shoud be adjustable depond upon their fone models or screen size..
my xml code-
<linearlayout xmlns:android="http://schemas.android.com/apk/res/android"> android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:removed="@drawable/pop_up_people"
android:orientation="vertical" >
<linearlayout> android:id="@+id/lin_scroll"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:layout_marginBottom="30dp"
android:layout_marginTop="40dp"
android:orientation="vertical" >
<scrollview>
android:id="@+id/scroller"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:layout_marginTop="16dip"
android:fadingEdgeLength="5dip" >
<linearlayout> android:id="@+id/tracks"
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:layout_weight="1"
android:orientation="horizontal"
android:paddingBottom="4dip"
android:paddingTop="4dip" />
<ImageView
android:id="@+id/arrow_up"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:src="@drawable/arrow_up"
android:visibility="gone" />
<ImageView

推荐答案
这是太长的代码来帮助你。总是尝试在你的imageview中使用
Thats too long code to help you. Always try to use
android:scaltype="fitXY"并注意你的imageview布局的高度和宽度。创建不同的图像（尤其是xhdpi，hdpi，mdpi和ldpi），支持各种设备，并始终使用9补丁图像。
请仔细遵循这些说明：
图像大小适合所有设备 [ ^ ]
inside your imageview and keep attention of your imageview layout's height and width.Create different images(especially xhdpi, hdpi, mdpi and ldpi) that supports wide range of devices and always use 9-patch images.
Follow these instructions carefully:
Image sizes to fit all devices[^]
