代碼的實現(xiàn):
第一個布局文件
<?xml version=“1.0“ encoding=“utf-8“?>
<Directionallayout
xmlns:ohos=“http://schemas.huawei.com/res/ohos“
ohos:height=“match_parent“
ohos:width=“match_parent“
ohos:orientation=“vertical“>
<Button
ohos:id=“$+id:text_01“
ohos:width=“match_content“
ohos:height=“match_content“
ohos:text_size=“30fp“
ohos:text=“Dialog顯示“
ohos:top_margin=“0vp“
ohos:text_color=“red“/>
</DirectionalLayout>
第二個布局文件
<?xml version=“1.0“ encoding=“utf-8“?>
<DirectionalLayout
xmlns:ohos=“http://schemas.huawei.com/res/ohos“
ohos:width=“match_parent“
ohos:height=“match_content“
ohos:padding=“10vp“
ohos:background_element=“grey“
ohos:orientation=“vertical“>
<Text
ohos:width=“match_parent“
ohos:height=“match_content“
ohos:text=“Dialog標題“
ohos:text_color=“Black“
ohos:text_style=“bold“
ohos:text_size=“40fp“/>
<Text
ohos:width=“match_parent“
ohos:height=“match_parent“
ohos:text=“自定義Dialog內(nèi)容“
ohos:text_color=“Black“
ohos:text_style=“bold“
ohos:weight=“1“
ohos:text_alignment=“vertical_center“
ohos:top_margin=“30vp“
ohos:bottom_margin=“30vp“
ohos:left_margin=“10vp“
ohos:right_margin=“10vp“
ohos:text_size=“30fp“/>
<DirectionalLayout
ohos:height=“match_content“
ohos:width=“match_parent“
ohos:orientation=“horizontal“>
<Button
ohos:width=“match_parent“
ohos:text=“取消“
ohos:text_size=“30fp“
ohos:padding=“10vp“
ohos:text_color=“White“
ohos:weight=“1“
ohos:margin=“10vp“
ohos:background_element=“yellow“
ohos:height=“match_content“/>
<Button
ohos:width=“match_parent“
ohos:text=“確定“
ohos:text_size=“30fp“
ohos:weight=“1“
ohos:padding=“10vp“
ohos:text_color=“White“
ohos:margin=“10vp“
ohos:background_element=“green“
ohos:height=“match_content“/>
</DirectionalLayout>
</DirectionalLayout>
然后進行綁定
package com.example.jltfdialog.slice;
import com.example.jltfdialog.ResourceTable;
import ohos.aafwk.ability.AbilitySlice;
import ohos.aafwk.content.Intent;
import ohos.agp.components.Button;
import ohos.agp.components.Component;
import ohos.agp.components.LayoutScatter;
import ohos.agp.window.dialog.CommonDialog;
public class MainAbilitySlice extends AbilitySlice {
@Override
public void onStart(Intent intent) {
super.onStart(intent);
CommonDialog commonDialog = new CommonDialog(this);
super.setUIContent(ResourceTable.
Layout_layout1);
Button button= (Button) findComponentById(ResourceTable.
Id_text_01);
button.setClickedListener(new Component.ClickedListener() {
@Override
public void onClick(Component component) {
Component component1 = LayoutScatter.
getInstance(getContext())
.parse(ResourceTable.
Layout_ability_main, null, true);
commonDialog.setSize(800, 500);
commonDialog.setContentCustomComponent(component1);
commonDialog.show();
}
});
}
@Override
public void onActive() {
super.onActive();
}
@Override
public void onForeground(Intent intent) {
super.onForeground(intent);
}
