直接上代碼：

public class ToastUtil {

    public static void show(Context context, String message) {
        if (context == null) {
            return;
        }
        DirectionalLayout component = (DirectionalLayout) LayoutScatter.getInstance(context).parse(ResourceTable.Layout_layout_toast, null, false);
        Text text = (Text) component.findComponentById(ResourceTable.Id_tvMessage);
        text.setText(message);
        new ToastDialog(context)
                .setContentCustomComponent(component)
                .setAlignment(LayoutAlignment.BOTTOM)
                .setTransparent(true)
                .show();
    }
}

這里我是用了 XML 寫了一個(gè)布局，可以按需實(shí)現(xiàn)。
重要的一個(gè)屬性

setTransparent(true) 

如果沒有設(shè)置透明屬性，最終的 Toast 會(huì)有一個(gè)系統(tǒng)的背景，達(dá)不到你自己想要的效果.

• 貼上 xml

<?xml version="1.0" encoding="utf-8"?>
<DirectionalLayout
    xmlns:ohos="http://schemas.huawei.com/res/ohos"
    ohos:height="match_content"
    ohos:width="match_content"
    ohos:background_element="$graphic:bg_toast"
    ohos:bottom_margin="80vp"
    ohos:orientation="vertical"
    >

    <Text
        ohos:id="$+id:tvMessage"
        ohos:height="match_content"
        ohos:width="match_content"
        ohos:left_margin="5vp"
        ohos:padding="10vp"
        ohos:right_margin="5vp"
        ohos:text="我是測(cè)試內(nèi)容"
        ohos:text_alignment="center"
        ohos:text_color="$color:white_65"
        ohos:text_size="17fp"
        />

</DirectionalLayout>
