请告诉我。感谢

是的,你只需添加颜色即可。
<?xml version="1.0" encoding="utf-8"?>
<shape xmlns:android="http://schemas.android.com/apk/res/android"
android:shape="rectangle">
<gradient
android:startColor="#83a4d4"
android:endColor="#b6fbff"
android:angle="45"/>
<corners
android:bottomRightRadius="10dp"
android:bottomLeftRadius="10dp"
android:topLeftRadius="10dp"
android:topRightRadius="10dp"/>
</shape>

是的,你可以做到! 您可以使用Shape Drawable来实现渐变效果。 可以在此处找到Shape Drawable XML文件的语法: http://developer.android.com/guide/topics/resources/drawable-resource.html#Shape
假设您使用以下内容制作了grad_bg.xml:
NSMutableArray
在应用程序的res / drawables /文件夹中准备好XML后,可以使用视图标记中的以下属性将其设置为背景,并将布局中的元素(如LinearLayout)设置为按钮和TextView等窗口小部件:
(
{
Realimg = "<UIImage: 0x13951b130>, {800, 600}";
"bid_accepted" = 1;
"bid_amount" = 100;
"bid_amount_num" = 100;
"bid_cur_name" = USD;
"bid_cur_symb" = $;
"bid_currencycode" = 4;
"bid_date" = "05 Nov 2015";
"bid_msg" = testing;
"bid_user_id" = 2;
"nego_id" = 612;
"pas_count" = 5;
"ride_address" = "Sample Address";
"ride_cover_img" = "uploadfiles/UploadUserImages/2/mobile/21426739600s-end-horton-plains.jpg";
"ride_id" = 149;
"ride_name" = "Ride to the World's End";
"ride_type_id" = 0;
"ride_type_name" = Travel;
"ride_user_fname" = Nik;
"ride_user_id" = 2;
"ride_user_lname" = Mike;
}
)
或像这样的代码:
<?xml version="1.0" encoding="utf-8"?>
<shape xmlns:android="http://schemas.android.com/apk/res/android">
<gradient android:angle="270" android:startColor="#00A4FF" android:endColor="#FFFFFF"/>
</shape>
一切顺利:)

正如仅供参考,也可以通过编程方式创建渐变。以下是可用于返回线性渐变的方法示例:
public static GradientDrawable createGradient(int startColor, int endColor, GradientDrawable.Orientation orientation) {
GradientDrawable returnGradient;
returnGradient =
new GradientDrawable(
orientation,
new int[] {startColor, endColor}
);
return returnGradient;
}
并称之为:
int startColor = getResources().getColor(R.color.accent);
int endColor = getResources().getColor(R.color.primary);
GradientDrawable.Orientation orientation = GradientDrawable.Orientation.TOP_BOTTOM;
GradientDrawable gradient = createGradient(startColor, endColor, orientation);
myView.setBackground(gradient);
