android调用php接口,Android 4.0调用http接口php网站的api

(本人菜鸟刚学)看网上教程写了一个很简单的HttpGet测试一下，结果出了一堆的报错！ 代码： public static String getApi(String url){ String cont = null; HttpGet httpGet = new HttpGet(url); DefaultHttpClient httpClient = new DefaultHttpClient();

(本人菜鸟刚学)看网上教程写了一个很简单的 HttpGet测试一下，结果出了一堆的报错！

代码：

public static String getApi(String url){

String cont = null;

HttpGet httpGet = new HttpGet(url);

DefaultHttpClient httpClient = new DefaultHttpClient();

try {

HttpResponse httpResponse = httpClient.execute(httpGet);

int reCode = httpResponse.getStatusLine().getStatusCode();

if (reCode == HttpStatus.SC_OK) {

cont = EntityUtils.toString(httpResponse.getEntity());

return cont;

}

} catch (ClientProtocolException e) {

e.printStackTrace();

} catch (IOException e) {

e.printStackTrace();

}

return "";

}

报线程问题，看网上资料说从2.3以后就必须在线程里面运行，然后网上各种写法，看到头大坑爹的而且写进来还不行，接着报错...然后...擦还是不行....还是自己写一下.....希望可以帮助到新手

在onCreate里面先初始化

handler=new Handler(); //当然最上面还要定义private Handler handler;

然后在你的触发事件里面写

public void login_submit(View v){

new Thread(){

@Override

public void run() {

String url = "http://192.168.1.188/123.html";

rs = HttpApi.getApi(url);

handler.post(new Runnable() {

@Override

public void run() {

Toast.makeText(login.this,rs,Toast.LENGTH_SHORT).show();

}

});

}}.start();

}

好这样就差不多了。最后还要在

AndroidManifest.xml 里面加入一句 允许联网的权限

OK搞定。。。。
