HarmonyOS原子化服务开发实战-地图导航

最近尝试了在开发的项目上添加打开三方应用的地图导航功能，下面是体验的详细代码。

package com.jltf.jltf_navigation.slice;
import com.jltf.jltf_navigation.ResourceTable;
import ohos.aafwk.ability.AbilitySlice;
import ohos.aafwk.content.Intent;
import ohos.agp.components.Component;
import ohos.agp.components.TextField;
import ohos.bundle.IBundleManager;
import ohos.hiviewdfx.HiLog;
import ohos.hiviewdfx.HiLogLabel;
import ohos.utils.net.Uri;
public class MainAbilitySlice extends AbilitySlice {
private static final HiLogLabel TAG = new HiLogLabel(HiLog.LOG_APP,0x0,"地图导航");
String address="北京市";
Uri uri;
@Override
public void onStart(Intent intent) {
super.onStart(intent);
super.setUIContent(ResourceTable.Layout_ability_main);
findComponentById(ResourceTable.Id_Nabtn).setClickedListener(new Component.ClickedListener() {
@Override
public void onClick(Component component) {
TextField textField = findComponentById(ResourceTable.Id_text);
address=textField.getText();
HiLog.info(TAG,"输入地址："+address);
if (isAppExist("com.tencent.map")){
// 腾讯地图
uri=Uri.parse( "qqmap://map/search?keyword=" + address);
}else if (isAppExist("com.autonavi.minimap")){
// 高德地图
uri=Uri.parse("androidamap://keywordNavi?sourceApplication="+getBundleName()+"&keyword="+address+"&style=2");
}else if (isAppExist("com.baidu.BaiduMap")){
uri=Uri.parse("baidumap://map/geocoder?src="+getBundleName()+"&address="+address); // 百度地图
}
Intent intent1=new Intent();
intent1.setUri(uri);
startAbility(intent1);
}
});
}
boolean isAppExist(String appPkg) {
try {
IBundleManager manager = this.getBundleManager();
return manager.isApplicationEnabled(appPkg);
} catch (IllegalArgumentException e) {
return false;
}
}
@Override
public void onActive() {
super.onActive();
}
@Override
public void onForeground(Intent intent) {
super.onForeground(intent);
}
}
