使用

引入

compile 'org.xutils:xutils:3.5.0'

增加MyApplication

public class Myapplication  extends Application {
    @Override
    public void onCreate() {
        super.onCreate();
        x.Ext.init(this);//初始化xutils控件
    }
}

AndroidManifest.xml

<application
        android:name=".Myapplication"
        ...... >
        ......
    </application>

1）Activity的注解的使用：

@ContentView(R.layout.activity_main)
public class MainActivity extends AppCompatActivity {
    @ViewInject(R.id.listView)
    private ListView listView;
    
    @Override
    protected void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        x.view().inject(this);
    }   
}

fragment中的注解

@ContentView(R.layout.fragment_home)
public class HomeFragment extends Fragment implements IHouseView {
    @Nullable
    @Override
    public View onCreateView(@NonNull LayoutInflater inflater, @Nullable ViewGroup container, @Nullable Bundle savedInstanceState) {
        return  x.view().inject(this,inflater,container);
    }
}

2）点击事件

方法必须私有限定

@Event(value = R.id.listView,type = AdapterView.OnItemClickListener.class)
    private void onItemClick(AdapterView<?> adapterView, View view, int i, long l) {
        Toast.makeText(MainActivity.this,i+"",Toast.LENGTH_SHORT).show();
    }

3）加载图片

AndroidManifest中增加权限

<uses-permission android:name="android.permission.INTERNET" />
<uses-permission android:name="android.permission.WRITE_EXTERNAL_STORAGE" />

class XutilsAdapter extends BaseAdapter {
        private ImageOptions options;
       ......

        public XutilsAdapter() {
            ......
            
            Animation animation = new ScaleAnimation(0,1,0,1);
            animation.setDuration(1000);
            animation.setRepeatCount(0);
            options = new ImageOptions.Builder()
                    .setAnimation(animation) //设置动画
                    .setLoadingDrawableId(R.mipmap.ic_launcher)
                    .setFailureDrawableId(R.mipmap.ic_launcher_round)
                    .setSize(200, 200) //设置大小
                    .setRadius(5)//设置拐角弧度
                    .build();
            //.setCircular(true) //设置图片显示为圆形
            //.setSquare(true) //设置图片显示为正方形
            //.setCrop(true)
            //.setFailureDrawable(Drawable failureDrawable) //设置加载失败的动画
            //.setLoadingDrawable(Drawable loadingDrawable) //设置加载中的动画
            //.setIgnoreGif(false) //忽略Gif图片
            //.setParamsBuilder(ParamsBuilder paramsBuilder) //在网络请求中添加一些参数
            //.setUseMemCache(true) //设置使用MemCache，默认true
        }

        ......

        @Override
        public View getView(int i, View view, ViewGroup viewGroup) {
            ......
            //批量加载图片
            x.image().bind(holder.ivPic, music.getPic_small(), options);
            return view;
        }
        ......
    }
