Android 应用程序中的布局和可绘制问题

发布于 2024-11-30 04:15:08 字数 845 浏览 0 评论 0原文

我经常对 Android 应用程序使用的图像大小和按钮大小感到困惑。

我知道按钮和图像必须放在 drawable、drawable-ldpi、drawable-mdpi、drawable- 等文件夹中hdpi、drawable-xhdpi 但我不清楚用于该应用程序的那些文件夹中提到的尺寸。

请帮我解释一下。例如，如果我在应用程序中使用背景图像，则默认图像的大小必须是多少，以及每个文件夹中要放置的大小是什么。

对于布局，我知道我必须使用 layout、layout-large、layout-small、layout 等文件夹-xlarge。例如，在此文件夹中，我有以下 xml 代码

<?xml version="1.0" encoding="utf-8"?>
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
    android:orientation="vertical"
    android:layout_width="fill_parent"
    android:layout_height="fill_parent"
    android:background="@drawable/splash_screen"
    >
</LinearLayout>

对于每个布局的 android:background 图像，从哪个文件夹获取图像？

I am often getting confused with the image sizes and button sizes that I am using for the android app.

I know that the buttons and images must be placed in folders such as drawable, drawable-ldpi, drawable-mdpi, drawable-hdpi, drawable-xhdpi but i am not clear the about the sizes to be mentioned in those folders that used for the app.

Please help me in explaining this. For example, if I am using a background image for my app, then what must be the size of the image in default and in each folder what sizes to be placed.

In case of the layout I know that I have to use folders such as layout, layout-large, layout-small, layout-xlarge. For example in this folder I am having the following xml code

<?xml version="1.0" encoding="utf-8"?>
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
    android:orientation="vertical"
    android:layout_width="fill_parent"
    android:layout_height="fill_parent"
    android:background="@drawable/splash_screen"
    >
</LinearLayout>

For the android:background image for each layout, from which folder is the image fetched?
