（1）代码创建布局

  1. package com.code.hmdemo.slice;
  2. import ohos.aafwk.ability.AbilitySlice;
  3. import ohos.aafwk.content.Intent;
  5. import ohos.agp.components.*;
  7. public class MainAbilitySlice extends AbilitySlice {
  9.     @Override
  10.     public void onStart(Intent intent) {
  11.         super.onStart(intent);
  13.         // 创建button
  14.         Button button1 = new Button(getContext());
  15.         button1.setWidth(ComponentContainer.LayoutConfig.MATCH_CONTENT);//包住内容
  16.         button1.setHeight(ComponentContainer.LayoutConfig.MATCH_CONTENT);//包住内容
  17.         button1.setText("btn111");
  18.         button1.setTextSize(25);
  20.         Button button2 = new Button(getContext());
  21.         button2.setWidth(ComponentContainer.LayoutConfig.MATCH_CONTENT);//
  22.         button2.setHeight(ComponentContainer.LayoutConfig.MATCH_CONTENT);
  23.         button2.setText("btn222");
  24.         button2.setTextSize(25);
  26.         // 布局容器
  27.         DirectionalLayout directionalLayout = new DirectionalLayout(getContext());
  28.         directionalLayout.setWidth(ComponentContainer.LayoutConfig.MATCH_PARENT);// 填充父容器
  29.         directionalLayout.setHeight(ComponentContainer.LayoutConfig.MATCH_PARENT);// 填充父容器
  30.         directionalLayout.setOrientation(Component.VERTICAL);
  32.         // 容器添加控件
  33.         directionalLayout.addComponent(button1);
  34.         directionalLayout.addComponent(button2);
  36.         // 设置页面布局
  37.         super.setUIContent(directionalLayout);
  38.     }
  40.     @Override
  41.     public void onActive() {
  42.         super.onActive();
  43.     }
  45.     @Override
  46.     public void onForeground(Intent intent) {
  47.         super.onForeground(intent);
  48.     }
  49. }

（2）XML创建布局

第一步

  • 创建 resources/base/layout 文件夹，并新建main_layout.xml文件

    1. <?xml version="1.0" encoding="utf-8"?>
    2. <DirectionalLayout xmlns:ohos="http://schemas.huawei.com/res/ohos"
    3.                  ohos:width="match_parent"
    4.                  ohos:height="match_parent"
    5.                  ohos:orientation="vertical">
    7.   <Button
    8.           ohos:width="match_parent"
    9.           ohos:height="50vp"
    10.           ohos:background_element="red"
    11.           ohos:text="11111"
    12.           />
    13.   <Button
    14.           ohos:width="match_parent"
    15.           ohos:height="50vp"
    16.           ohos:background_element="red"
    17.           ohos:text="222"
    18.           />
    19. </DirectionalLayout>

    第二步

  • 使用当前包名下的ResourceTable

  • 真正的资源id是 Layout_布局文件名 ``` package com.code.hmdemo.slice; import com.code.hmdemo.ResourceTable; import ohos.aafwk.ability.AbilitySlice; import ohos.aafwk.content.Intent;

public class MainAbilitySlice extends AbilitySlice {

  1. @Override
  2. public void onStart(Intent intent) {
  3.     super.onStart(intent);
  4.     super.setUIContent(ResourceTable.Layout_main_layout);
  5. }
  7. @Override
  8. public void onActive() {
  9.     super.onActive();
  10. }
  12. @Override
  13. public void onForeground(Intent intent) {
  14.     super.onForeground(intent);
  15. }

} ```
