如何在Android Studio中的相应Android设备中获取适当的图像

我正在设计音乐播放器的布局,但是当我使用虚拟设备Nexus 5渲染时,我根本不会遇到任何问题

但是当我用Nexus 7渲染时

它显示相同大小的图像.

发布我的照片的屏幕截图.

希望能得到你们的一些解决方案.

解决方法:

您必须遵循此操作才能支持多个设备：

屏幕密度的变化.

xlarge screens are at least 960dp x 720dp
large screens are at least 640dp x 480dp
normal screens are at least 470dp x 320dp
small screens are at least 426dp x 320dp

制作此布局文件,以便它对所有设备都相同.

res/layout/main_activity.xml           # For handsets (smaller than 600dp available width)
res/layout-sw600dp/main_activity.xml   # For 7” tablets (600dp wide and bigger)
res/layout-sw720dp/main_activity.xml   # For 10” tablets (720dp wide and bigger)

对于布局,

res/layout/my_layout.xml              // layout for normal screen size ("default")
res/layout-large/my_layout.xml        // layout for large screen size
res/layout-xlarge/my_layout.xml       // layout for extra-large screen size
res/layout-xlarge-land/my_layout.xml  // layout for extra-large in landscape orientation

对于图像

res/drawable-mdpi/graphic.png         // bitmap for medium-density
res/drawable-hdpi/graphic.png         // bitmap for high-density
res/drawable-xhdpi/graphic.png        // bitmap for extra-high-density
res/drawable-xxhdpi/graphic.png       // bitmap for extra-extra-high-density

对于图标

res/mipmap-mdpi/my_icon.png         // launcher icon for medium-density
res/mipmap-hdpi/my_icon.png         // launcher icon for high-density
res/mipmap-xhdpi/my_icon.png        // launcher icon for extra-high-density
res/mipmap-xxhdpi/my_icon.png       // launcher icon for extra-extra-high-density
res/mipmap-xxxhdpi/my_icon.png      // launcher icon for extra-extra-extra-high-density

对于Launcher图标

36x36 (0.75x) for low-density
48x48 (1.0x baseline) for medium-density
72x72 (1.5x) for high-density
96x96 (2.0x) for extra-high-density
180x180 (3.0x) for extra-extra-high-density
192x192 (4.0x) for extra-extra-extra-high-density (launcher icon only; see note above)

NOTE: Always try to use SP whenever you deal with textSize, like textsize=12sp

使用预定义的textAppearance：

It will set text size automatically as per device density.

    <TextView android:textAppearance="?android:attr/textAppearanceSmall"/>
    <TextView android:textAppearance="?android:attr/textAppearanceMedium"/>
    <TextView android:textAppearance="?android:attr/textAppearanceLarge" />
Sample usage:

    <TextView
        style="@android:style/TextAppearance.Small"
        android:text="Sample Text - Small" />
    <TextView
        style="@android:style/TextAppearance.Medium"
        android:text="Sample Text  - Medium" />
    <TextView
        style="@android:style/TextAppearance.Large"
        android:text="Sample Text  - Large" />
