不常用

在PositionLayout中，子组件通过指定准确的x/y坐标值在屏幕上显示。(0, 0)为左上角；当向下或向右移动时，坐标值变大；允许组件之间互相重叠

布局方式

PositionLayout以坐标的形式控制组件的显示位置，允许组件相互重叠。

• 在layout目录下的XML文件中创建PositionLayout并添加多个组件，并通过position_x和position_y属性设置子组件的坐标

<?xml version="1.0" encoding="utf-8"?>
<PositionLayout
    xmlns:ohos="http://schemas.huawei.com/res/ohos"
    ohos:height="match_parent"
    ohos:width="match_parent"
    >

    <Text
        ohos:id="$+id:text_1"
        ohos:height="match_content"
        ohos:width="match_content"
        ohos:background_element="#FF485DEC"
        ohos:layout_alignment="horizontal_center"
        ohos:text="科技"
        ohos:text_size="40vp"
        />

</PositionLayout>

Text text = (Text) findComponentById(ResourceTable.Id_text_1);

设置显示位置

text.setContentPosition(200,300);

package com.example.myapplication.slice;

import com.example.myapplication.ResourceTable;
import ohos.aafwk.ability.AbilitySlice;
import ohos.aafwk.content.Intent;
import ohos.agp.components.Text;

public class MainAbilitySlice extends AbilitySlice {
    @Override
    public void onStart(Intent intent) {
        super.onStart(intent);
        super.setUIContent(ResourceTable.Layout_ability_main);
        Text text = (Text) findComponentById(ResourceTable.Id_text_1);
        text.setContentPosition(200,300);
    }

    @Override
    public void onActive() {
        super.onActive();
    }

    @Override
    public void onForeground(Intent intent) {
        super.onForeground(intent);
    }
}
