Xutils请求数据,加载图片基本使用方法

public class MyApplication extends Application {
@Override
public void onCreate() {
super.onCreate();
x.Ext.init(this);
}
}

@ContentView(R.layout.activity_main)//代替了setContentView(R.layout.activity_main)
public class MainActivity extends AppCompatActivity {

@ViewInject(R.id.img)//等同于findViewById(R.id.img);
ImageView img;

@Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
//        setContentView(R.layout.activity_main);
x.view().inject(this);
//设置图片
setImage();
}

//注册点击事件,方法类型必须是私有的private,不需要在布局中添加OnClick属性
@Event(type = View.OnClickListener.class, value = R.id.btn_text)
private void textOnClick(View view) {
Toast.makeText(this, "我通过Event注册了点击事件", Toast.LENGTH_SHORT).show();
}

//长按的点击事件注册,返回值必须是boolean
@Event(type = View.OnLongClickListener.class, value = R.id.text_get)
private boolean TestGet(View view) {
String path = "http://********************";
RequestParams params = new RequestParams(path);
params.addQueryStringParameter("key", "8888888888888888888888");
x.http().get(params, new Callback.CommonCallback<String>() {
@Override//请求成功
public void onSuccess(String result) {
Toast.makeText(MainActivity.this, "Get请求成功", Toast.LENGTH_SHORT).show();
System.out.println("get请求到的数据============" + result);
}

@Override
public void onError(Throwable ex, boolean isOnCallback) {
}

@Override
public void onCancelled(CancelledException cex) {
}

@Override
public void onFinished() {
}
});
return true;
}

//post请求数据,长按的点击事件,返回值必须是boolean
@Event(type = View.OnLongClickListener.class, value = R.id.text_post)
private boolean TestPost(View view) {
String path = "http://********************";
RequestParams params = new RequestParams(path);
params.addBodyParameter("key", "88888888888888888888888");
x.http().post(params, new Callback.CommonCallback<String>() {
@Override
public void onSuccess(String result) {
Toast.makeText(MainActivity.this, "Post请求成功", Toast.LENGTH_SHORT).show();
System.out.println("Post请求数据:====" + result);
}

@Override
public void onError(Throwable ex, boolean isOnCallback) {
}

@Override
public void onCancelled(CancelledException cex) {
}

@Override
public void onFinished() {
}
});
return true;
}

private void setImage() {
ImageOptions builder = new ImageOptions.Builder()
.setCrop(true)
.setFadeIn(true)
.setSize(50, 50)
.setUseMemCache(true)
.build();
x.image().bind(img, "http://zxpic.gtimg" +
".com/infonew/0/wechat_pics_-214279.jpg/168");
