【Harmony OS】【JAVA UI】abilitySlice和ability跳转方式

 Ability跳转方式

准备阶段

参考资料 AbilitySlice间导航，Intent，Ability

新建TwoAbility界面（如下图所示）

1、startAbility

mainAbilitySlice代码如下

 Intent intent=new Intent();  Operation operation=new Intent.OperationBuilder()   .withBundleName(getBundleName())   .withAbilityName(TwoAbility.class.getName())   .build();  intent.setOperation(operation);  startAbility(intent);

2、startAbilityForResult

mainAbilitySlice 写startAbilityForResult

 Intent intent = new Intent();  Operation operation = new Intent.OperationBuilder()   .withBundleName(getBundleName())   .withAbilityName(TwoAbility.class.getName())   .build();  intent.setOperation(operation);  startAbilityForResult(intent, 1001);

在mainAbilitySlice 重写onAbilityResult的方法，代码如下

@Override    protected void onAbilityResult(int requestCode, int resultCode, Intent resultData) { super.onAbilityResult(requestCode, resultCode, resultData); if (requestCode == 1001 && resultCode == 1002) {     IntentParams myIntentParams= resultData.getParams();    String value= (String) myIntentParams.getParam("key");     System.err.println("#####" + value); }    }

在TwoAbilitySlice调用setResult的方法

Intent intent=new Intent();  intent.setParam("key","value");  getAbility().setResult(1002,intent);  terminateAbility();//todo 关闭该Ability

AbilitySlice跳转方式

同一Page内导航

1、present

在mainAbilitySlice写代码如下

  present(new TwoAbilitySlice(),new Intent());

2、presentForResult

在mainability使用presentForResult的方法，代码如下

  presentForResult(new TwoAbilitySlice(),new Intent(),1003);

在mainabilitySlice重写onResult的方法，代码如下

    @Override    protected void onResult(int requestCode, Intent resultIntent) { if (requestCode == 1003) {     IntentParams intentParams=  resultIntent.getParams();     String value= (String) intentParams.getParam("key");     System.err.println("#####"+value); }    }

在TwoabilitySlice实现点击并关闭该界面

  Intent intent=new Intent();  intent.setParam("key","value"); setResult(intent);  terminate();//todo 关闭该AbilitySlice

不同Page间导航

1、准备工作

在MainAbility的onStart方法中调用addActionRoute的方法，代码如下

 @Override    public void onStart(Intent intent) { super.onStart(intent); super.setMainRoute(MainAbilitySlice.class.getName()); addActionRoute("com.pay", TwoAbilitySlice.class.getName());    }

2、在mainAbilitySlice调用 startAbility的方法，代码如下

  Intent intent=new Intent();  Operation operation=new Intent.OperationBuilder()   .withBundleName(getBundleName())   .withAction("com.pay")//todo action 要和TwoAbilitySlice的action相同   .withAbilityName(MainAbility.class.getName())   .build();  intent.setOperation(operation);  startAbility(intent);
