自动下载gradle

耗时3个小时完工

代码如下： ability_main.xml

MainAbility.java

package com.example.demo;import com.example.demo.slice.MainAbilitySlice;import ohos.aafwk.ability.Ability;import ohos.aafwk.content.intent;import ohos.agp.components.Button;import ohos.agp.components.Component;import ohos.agp.components.Text;import ohos.agp.components.TextField;public class MainAbility extends Ability { @Override public void onStart(Intent intent) { super.onStart(intent); super.setUIContent(ResourceTable.Layout_ability_main); super.setMainRoute(MainAbilitySlice.class.getName()); Button button_add = (Button) findComponentById(ResourceTable.Id_add); button_add.setClickedListener(new Component.ClickedListener(){ @Override public void onClick(Component component) { TextField text_x = (TextField) findComponentById(ResourceTable.Id_x); int x = Integer.parseInt(text_x.getText()); TextField text_y = (TextField) findComponentById(ResourceTable.Id_y); int y = Integer.parseInt(text_y.getText()); int result = x y; TextField text_result = (TextField) findComponentById(ResourceTable.Id_result); text_result.setText(String.valueOf(result)); System.out.println(result); } }); } @Override public void onActive() { super.onActive(); } @Override public void onForeground(Intent intent) { super.onForeground(intent); }}

明天做好签名准备打包hap
