华为Pura80系列鸿蒙系统兼容性？第三方应用适配指南

// 使用鸿蒙原生SDK开发一个简单的应用
import ohos.ace.ability.AceAbility;
import ohos.ace.ability.AceAbilitySlice;
import ohos.agp.components.Text;
import ohos.agp.utils.TextAlignment;

public class MainAbility extends AceAbility {
    @Override
    public void onStart(Intent intent) {
        super.onStart(intent);
        MainAbilitySlice mainAbilitySlice = new MainAbilitySlice();

// 界面适配示例
import ohos.agp.components.ComponentContainer;
import ohos.agp.components.DirectionalLayout;
import ohos.agp.components.Text;
import ohos.agp.utils.LayoutAlignment;

        Text text = new Text(this);
        text.setText("Adapted UI for HarmonyOS");
        text.setLayoutAlignment(LayoutAlignment.CENTER);

        layout.addComponent(text);
        rootLayout.addComponent(layout);
    }
}

// 功能适配示例
import ohos.rpc.RemoteException;
import ohos.system.Parameters;

public class FunctionAdapterExample extends AceAbilitySlice {
    @Override
    public void onStart(Intent intent) {
        super.onStart(intent);
        try {
            String deviceName = Parameters.getDeviceName();
            Text text = new Text(this);
            text.setText("Device Name: " + deviceName);
            rootLayout.addComponent(text);
        } catch (RemoteException e) {
            e.printStackTrace();
        }
    }
}

// 性能优化示例
import ohos.distributedschedule.interwork.DeviceInfo;
import ohos.distributedschedule.interwork.DeviceManager;

public class PerformanceOptimizationExample extends AceAbilitySlice {
    @Override
    public void onStart(Intent intent) {
        super.onStart(intent);
        DeviceManager deviceManager = DeviceManager.getInstance();
        List<DeviceInfo> devices = deviceManager.getDeviceList(DeviceInfo.FLAG_GET_ONLINE_DEVICE);

        if (!devices.isEmpty()) {
            DeviceInfo device = devices.get(0);
            // 在其他设备上执行计算任务
            // 这里只是一个示例，实际操作需要根据具体需求实现
            Text text = new Text(this);
            text.setText("Using device: " + device.getDeviceName());
            rootLayout.addComponent(text);
        }
