yoga是facebook打造的一个跨IOS、Android、Window平台在内的布局引擎，兼容Flexbox布局方式，让界面更加简单。
Yoga官网：https://facebook.github.io/yoga/
官网上描述的特性包括：
目前在已开源的鸿蒙组件（https://gitee.com/openharmony-tpc/yoga）的功能现状如下：
首先我们在MainAbility中定义界面路由
public class MainAbility extends Ability {
@Override
public void onStart(Intent intent) {
super.onStart(intent);
super.setMainRoute(MainAbilitySlice.class.getName());
addActionRoute("action.dydrawnode.slice", DynamicsDrawNodeSlice.class.getName());
addActionRoute("action.showrow.slice", ShowRowAbilitySlice.class.getName());
addActionRoute("action.inflate.slice", BenchmarkInflateAbilitySlice.class.getName());
}
}
然后我们来到MainAbilitySlice,其实就是做了一个向其他界面跳转的动作，并提前加载yoga的so库
public class MainAbilitySlice extends AbilitySlice {
static {
System.loadLibrary("yoga");
System.loadLibrary("yogacore");
System.loadLibrary("fb");
}
@Override
public void onStart(Intent intent) {
super.onStart(intent);
setUIContent(ResourceTable.Layout_main_layout);
Button btn0= (Button) findComponentById(ResourceTable.Id_btn_1);
btn0.setClickedListener(component -> {
Intent intent1 = new Intent();
Operation operation = new Intent.OperationBuilder()
.withAction("action.dydrawnode.slice")
.build();
intent1.setOperation(operation);
startAbilityForResult(intent1, 1);
});
Button btn2= (Button) findComponentById(ResourceTable.Id_btn_2);
btn2.setClickedListener(component -> {
Intent intent1 = new Intent();
Operation operation = new Intent.OperationBuilder()
.withAction("action.showrow.slice")
.build();
intent1.setOperation(operation);
startAbilityForResult(intent1, 1);
});
Button btn1= (Button) findComponentById(ResourceTable.Id_btn_3);
btn1.setClickedListener(component -> {
Intent intent1 = new Intent();
Operation operation = new Intent.OperationBuilder()
.withAction("action.inflate.slice")
.build();
intent1.setOperation(operation);
startAbilityForResult(intent1, 1);
});
}
@Override
public void onActive() {
super.onActive();
}
@Override
public void onForeground(Intent intent) {
super.onForeground(intent);
}
