同一Page内导航
当发起导航的AbilitySlice和导航目标的AbilitySlice处于同一个Page时，您可以通过present()方法实现导航。如下代码片段展示通过点击按钮导航到其他AbilitySlice的方法：
public class MainAbilitySlice extends AbilitySlice {
//terminate
private Button btnNext;
@Override
public void onStart(Intent intent) {
super.onStart(intent);
super.setUIContent(ResourceTable.Layout_ability_main);
btnNext = (Button) findComponentById(ResourceTable.Id_btn_next);
btnNext.setClickedListener(listener ->{
SecondAbilitySlice abilitySlice = new SecondAbilitySlice();
Intent intent1 = new Intent();
intent1.setParam("params","来啦");
present(abilitySlice,intent1);
});
}
@Override
public void onActive() {
super.onActive();
}
@Override
public void onForeground(Intent intent) {
super.onForeground(intent);
}
}
在SecondAbilitySlice中进行接收数据
public class SecondAbilitySlice extends AbilitySlice {
private Button btnBack;
private Text text;
@Override
protected void onStart(Intent intent) {
super.onStart(intent);
super.setUIContent(ResourceTable.Layout_ability_second);
text = (Text)findComponentById(ResourceTable.Id_text_second);
if(intent!=null){
String params = intent.getStringParam("params");
if(!params.isEmpty()){
text.setText(params);
}
}
btnBack = (Button)findComponentById(ResourceTable.Id_btn_back) ;
btnBack.setClickedListener(listener->{
onBackPressed();
});
}
}
某些特定情况下 可能存在跳转即关闭跳转前PageAbilitySlice
跳转后代码添加：onBackPressed();
