android view databinding

如果需要使用安卓的 view databinding，首页需要在app目录下的build.gradle下设置

android {

// viewBinding
buildFeatures {
viewBinding true
}

}

然后再activity下面编写代码

public class GestureActivity extends AppCompatActivity {
private ActivityGestureBinding activityGestureBinding;
@Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
activityGestureBinding = ActivityGestureBinding.inflate(getLayoutInflater());
setContentView(activityGestureBinding.getRoot());
}
