android中的wordpress json解析

我没有在我的Android应用程序中获得帖子。这是我的MainActivity源代码

我正在Android设备上直接运行此应用程序。并且在我的设备上启用了Internet连接。它仅显示加载柱和封存发生的情况..：

public class MainActivity extends Activity {
ListView postList;

ArrayList<String> postArrayList=new ArrayList<String>();
ArrayAdapter<String> postAdapter;
Context context;
String feedUrl="http://www.aurangabadhq.com/?json=get_recent_posts";

@Override
protected void onCreate(Bundle savedInstanceState) {
    super.onCreate(savedInstanceState);
    setContentView(R.layout.activity_main);
    context=this;
    postList = (ListView) findViewById(R.id.postList);
    postAdapter = new ArrayAdapter<String>(this,R.layout.post_list_item, postArrayList);
    postList.setAdapter(postAdapter);
    PostListTask loaderTask=new PostListTask();
    loaderTask.execute();
}


@Override
public boolean onCreateOptionsMenu(Menu menu) {
    // Inflate the menu; this adds items to the action bar if it is present.
    getMenuInflater().inflate(R.menu.main, menu);
    return true;
}
public class PostListTask extends AsyncTask<Void,Void,Void>{
    ProgressDialog dialog;

    @Override
    protected void onPreExecute() {
        dialog= new ProgressDialog(context);
        dialog.setTitle("Loading Posts...");
        dialog.show();
        super.onPreExecute();
    }



    @Override
    protected Void doInBackground(Void... params)
    {
        HttpClient client=new DefaultHttpClient();
        HttpGet getRequest=new HttpGet(feedUrl);
        try {
            HttpResponse response=client.execute(getRequest);
            StatusLine StatusLine= response.getStatusLine();
            int statusCode=StatusLine.getStatusCode();

            if(statusCode !=200 )
            {
                return null;
            }
            InputStream jsonStream=response.getEntity().getContent();
            BufferedReader reader=new BufferedReader(new InputStreamReader(jsonStream));
            StringBuilder builder=new StringBuilder();
            String line;
            while((line=reader.readLine())!=null)
            {
                builder.append(line);
            }
            String jsonData=builder.toString();
            JSONObject json=new JSONObject(jsonData);
            JSONObject object=new JSONObject("object");
            JSONArray posts=new JSONArray("posts");
            for(int i=0;i<posts.length();i++)
            {
                JSONObject post=posts.getJSONObject(i);

                postArrayList.add(post.getString("title"));
            }



        } catch (IOException e) {
            e.printStackTrace();
        } catch (JSONException e) {
            e.printStackTrace();
        }
        return null;
    }

    @Override
    protected void onPostExecute(Void aVoid) {
        dialog.dismiss();
        postAdapter.notifyDataSetChanged();
        super.onPostExecute(aVoid);
    }

}

@Override
public boolean onOptionsItemSelected(MenuItem item) {
    // Handle action bar item clicks here. The action bar will
    // automatically handle clicks on the Home/Up button, so long
    // as you specify a parent activity in AndroidManifest.xml.
    int id = item.getItemId();
    if (id == R.id.action_settings) {
        return true;
    }
    return super.onOptionsItemSelected(item);
}

您能够从web获取Json吗

试试这个：

JSONObject json=new JSONObject(jsonData);
JSONArray posts = json.getJSONArray("posts");
for(int i = 0; i < posts.length(); i++) {
     JSONObject post=posts.getJSONObject(i);
     postArrayList.add(post.getString("title"));
}

不确定这是否有效，因为我还没有检查您的json。我建议尝试记录jsonData字符串，看看您是否从网络中获取json

Thanx用于快速响应。。但是。。什么也看不出来。！请检查我的json。。我想代码中没有错误。。你可以在这里检查我的json，所以如果你把Log.dYourApp，jsonData；就在while声明之后，Logcat中是否显示任何内容？ddms:无法绑定到调试器的本地8600 ddmlib:已建立的连接被主机中的软件中止java.io.IOException:已建立的连接被主机中的软件中止，位于sun.nio.ch.SocketDispatcher.write0Native方法java:51在sun.nio.ch.IOUtil.writeFromNativeBufferIOUtil.java:93在sun.nio.ch.IOUtil.WriteOutil.java:65在sun.nio.ch.SocketChannelImpl.writeSocketChannelImpl.java:487com.android.ddmlib.jdPacket.WriteAndConsumejdPacket.java:213在com.andAndroid.ddmlib.Client.sendAndConsumeClient.java:675java:342在com.android.ddmlib.Client.requestAllocationStatusClient.java:521在com.android.ddmlib.DeviceMonitor.createClientDeviceMonitor.java:831在com.android.ddmlib.DeviceMonitor.openClientDeviceMonitor.java:799在com.android.ddmlib.DeviceMonitor.deviceClientMonitorLoopDeviceMonitor.java:617位于com.android.ddmlib.DeviceMonitor.access$100DeviceMonitor.java:44位于$3.runDeviceMonitor.java:576
