#ViewBing的使用
android {
...
//根据版本自行选择
//3.6
viewBinding {
enabled = true
}
//4.0
buildFeatures {
viewBinding true
}
}
如果要在生成绑定类时忽略布局文件，则将tools:viewBindingIgnore="true"属性添加到该布局文件的根视图：
<androidx.constraintlayout.widget.ConstraintLayout
...
tools:viewBindingIgnore="true" >
...
</androidx.constraintlayout.widget.ConstraintLayout>
在activities中使用
private ActivityMainBinding binding;
@Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
binding = ActivityMainBinding.inflate(getLayoutInflater());
View view = binding.getRoot();
setContentView(view);
}
binding.name.setText("Hello World"));
binding.button.setOnClickListener(new View.OnClickListener() {
});
在fragment中使用
private FragmentBinding binding;
@Override
public View onCreateView (LayoutInflater inflater, ViewGroup container, Bundle savedInstanceState) {
binding = FragmentBinding.inflate(inflater, container, false);
View view = binding.getRoot();
return view;
}
@Override
public void onDestroyView() {
super.onDestroyView();
binding = null;
}
binding.name.setText("Hello World");
binding.button.setOnClickListener(new View.OnClickListener() {
});
