有两种方法可以使更改值为MutableLiveData.但是101和102比MutableLiveData有什么不同呢？
我找不到同样的文件.
这是安卓MutableLiveData级.
package android.arch.lifecycle;
/**
* {@link LiveData} which publicly exposes {@link #setValue(T)} and {@link #postValue(T)} method.
*
* @param <T> The type of data hold by this instance
*/
@SuppressWarnings("WeakerAccess")
public class MutableLiveData<T> extends LiveData<T> {
@Override
public void postValue(T value) {
super.postValue(value);
}
@Override
public void setValue(T value) {
super.setValue(value);
}
}
