Android Xutils框架使用之ViewUtils

import com.lidroid.xutils.view.annotation.event.OnClick;

//要告诉当前的MainActivity布局

@ContentView(R.layout.activity_main)
public class MainActivity extends AppCompatActivity {

//    使用ViewUtils查找控件
@ViewInject(R.id.btnMoveImg)
private Button btnMoveImg;
//    使用注解接收的变量 必须在注解的下一行代码
@ViewInject(R.id.showImage)
private ImageView showImage;

//    查找资源文件
@ResInject(id=R.anim.move,type = ResType.Animation)
private Animation move;

@Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
//setContentView(R.layout.activity_main);

//        注册ViewUtils
ViewUtils.inject(this);

//        一行代码效率会高
Fragment viewFragment=new ViewFragment();
getSupportFragmentManager().beginTransaction().add(R.id.container,viewFragment).addToBackStack(null).commit();

//        btnMoveImg.setOnClickListener(new View.OnClickListener() {
//            @Override
//            public void onClick(View v) {
//                showImage.startAnimation(move);
//            }
//        });
}

//            使用注解 设置点击事件
@OnClick(R.id.btnMoveImg)
public void btnMove(View view){

showImage.startAnimation(move);
