这是我的xml布局文件:
<layout xmlns:android="http://schemas.android.com/apk/res/android"
xmlns:app="http://schemas.android.com/apk/res-auto"
xmlns:tools="http://schemas.android.com/tools">
<data>
<import type="android.view.View" />
<variable
name="handler"
type="com.myproject.AdSettingsFragment" />
</data>
<android.support.constraint.ConstraintLayout
android:layout_width="match_parent"
android:layout_height="match_parent">
<android.support.v7.widget.SwitchCompat
android:id="@+id/pushSwitchCompat"
android:layout_width="0dp"
android:layout_height="wrap_content"
android:checked="true"
android:onCheckedChanged="@{(switch, checked) -> handler.onCheckedChanged(checked)}"
android:theme="@style/SwitchCompatTheme"/>
</android.support.constraint.ConstraintLayout>
</layout>
这里我要处理的java代码点击SwitchCompat组件:
public class AdSettingsFragment extends Fragment {
@Nullable
@Override
public View onCreateView(LayoutInflater inflater, @Nullable ViewGroup container, @Nullable Bundle savedInstanceState) {
AdvertisingSettingsBinding binding = DataBindingUtil.inflate(inflater, R.layout.advertising_settings, container, false);
return binding.getRoot();
}
public void onCheckedChanged(boolean isChecked) {
}
}
但是当我点击组件SwitchCompat
时,我的片段onCheckedChanged
中的方法AdSettingsFragment.java
不会被调用。
为什么不工作?
