xutils的http模块的简单使用

先导入xutils相关依赖：
compile 'org.xutils:xutils:3.5.0'

添加权限设置：
<uses-permission android:name="android.permission.INTERNET" />
<uses-permission android:name="android.permission.WRITE_EXTERNAL_STORAGE" />

在清单文件中加入application，在自己的Application中添加初始化设置：
@Override
    public void onCreate() {
        super.onCreate();
        x.Ext.init(this);
        x.Ext.setDebug(BuildConfig.DEBUG); // 是否输出debug日志, 开启debug会影响性能.
    }

Activity请求实现：

public class MainActivity extends AppCompatActivity implements View.OnClickListener {

    private WebView wvInfo;
    private Button btnRequest;

    public static final String url = "https://www.baidu.com/";

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

        findAndBind();

    }

    private void findAndBind(){
        wvInfo = (WebView) findViewById(R.id.wv_info);
        wvInfo.getSettings().setJavaScriptEnabled(true);
        wvInfo.setWebChromeClient(new WebChromeClient());
        btnRequest = (Button)findViewById(R.id.btn_request);
        btnRequest.setOnClickListener(this);
    }

    @Override
    public void onClick(View v) {
        switch (v.getId()){
            case R.id.btn_request:
                httpRequest();
                break ;
        }
    }

    private void httpRequest(){
        RequestParams params = new RequestParams(url);
//        params.setSslSocketFactory(); // 设置ssl
//        params.addQueryStringParameter("wd", "xUtils");

        x.http().get(params, new Callback.CommonCallback<String>() {
            @Override
            public void onSuccess(String result) {
                wvInfo.loadDataWithBaseURL(null,result, "text/html", "utf-8", null);
                Toast.makeText(x.app(), result, Toast.LENGTH_LONG).show();
            }

            @Override
            public void onError(Throwable ex, boolean isOnCallback) {
                Toast.makeText(x.app(), ex.getMessage(), Toast.LENGTH_LONG).show();
            }

            @Override
            public void onCancelled(CancelledException cex) {
                Toast.makeText(x.app(), "cancelled", Toast.LENGTH_LONG).show();
            }

            @Override
            public void onFinished() {

            }
        });
    }
}
