我正在尝试将我的应用程序与社交网络（Facebook和Twitter）集成。
我希望能够对用户墙或公共墙进行例证并将其发布到我的布局中，例如滚动视图或项目视图（或任何sugestions !!!），这是针对twitter解决的，但是我不能把这项工作交给facebook。
我使用的是图谱API。
要在我的墙上发帖，我创建方法 postTextOnMyWall ：
public String postTextOnMyWall(String message) {
Log.d("Tests", "Testing graph API wall post");
try {
Bundle parameters = new Bundle();
parameters.putString("message", message);// key/value
this.mAsyncRunner.request("me/feed", parameters, "POST",
new WallPostTextRequestListener(), null);
} catch (Exception e) {
e.printStackTrace();
}
return message;
}
public AsyncFacebookRunner getmAsyncRunner() {
return this.mAsyncRunner;
}
public void setmAsyncRunner(AsyncFacebookRunner mAsyncRunner) {
this.mAsyncRunner = mAsyncRunner;
}
}
此方法作为发布短信的侦听器 WallPostTextRequestListener
public class WallPostTextRequestListener implements RequestListener {
public void showToast(String message) {
Toast.makeText(getApplicationContext(), message, Toast.LENGTH_SHORT)
.show();
}
// called on successful completion of the Request
@Override
public void onComplete(String response, Object state) {
Log.d("WallPostTextRequestListener", "Got response: " + response);
String message = "<empty>";
try {
JSONObject json = Util.parseJson(response);
message = json.getString("message");
showToast("Mensagem escrita no teu mural facebook!: " + message);
} catch (JSONException e) {
Log.e("WallPostTextRequestListener", "JSON Error in response");
} catch (FacebookError e) {
Log.e("WallPostTextRequestListener",
"Facebook Error: " + e.getMessage());
}
final String text = "Mensagem: " + message;
}
@Override
public void onIOException(IOException e, Object state) {
// TODO Auto-generated method stub
}
@Override
public void onFileNotFoundException(FileNotFoundException e,
Object state) {
// TODO Auto-generated method stub
}
@Override
public void onMalformedURLException(MalformedURLException e,
Object state) {
// TODO Auto-generated method stub
}
// called if there is an error
@Override
public void onFacebookError(FacebookError e, Object state) {
// TODO Auto-generated method stub
}
}
他们只是使用facebook登录的对象在onClick按钮上发帖子
// this is the editext where i write my post
String messageFace = ((EditText) findViewById(R.id.message))
.getText().toString();
lf.postTextOnMyWall(messageFace);
如何从墙上或公共页面获取Feed？ 提前致谢！
答案 0 :(得分：1)
经过一段时间来解决这个问题，我在同事的帮助下找到了解决方案。
我们将创建一个HashMap传递它2两个字符串，例如，一个用于评论，另一个用于帖子的作者。在我们将在上面的onComplete方法的末尾创建另一个活动的意图之后，所以这必须看起来像这样：
public void onComplete(String response, Object state) {
Log.d("getFeedfromWallRequestListener", "Got response: "
+ response);
try {
JSONObject json = Util.parseJson(response);
Log.d("TESTE", "MY FEED EM JSON: " + json);
String comments;
String names;
//Show all the comments and names
JSONArray jArray=(JSONArray)json.get("data");
for(int i=0;i<(jArray.length());i++)
{
//jArray.getJSONObject(i).getJSONObject("from").get("name");
//jArray.getJSONObject(i).get("message");
HashMap<String, String> map = new HashMap<String, String>();
comments = jArray.getJSONObject(i).get("message").toString();
names = jArray.getJSONObject(i).getJSONObject("from").get("name").toString();
map.put("comments", comments);
map.put("names", names);
mylist.add(map);
Log.d("NAMES","Names: " + names);
Log.d("Comments","Comments: " + comments);
}
//showToast("Json com resposta do teu mural facebook!: " + json);
} catch (JSONException e) {
Log.w("getFeedfromWallRequestListener",
"JSON Error in response");
} catch (FacebookError e) {
Log.w("getFeedfromWallRequestListener", "Facebook Error: "
+ e.getMessage());
}
Intent intent = new Intent("android.intent.action.FacebookList");
intent.putExtra("arraylist", mylist);
try {
Log.i("TAG", "starting activity(android.intent.action.FacebookList)");
/*
*
*/
startActivity(intent);
} catch (Exception e) {
Log.e("TAG", "error when trying to start activity: " + e.getMessage());
for (int n = 0; n < e.getStackTrace().length; n++) {
Log.e("TAG", "stack: " + e.getStackTrace()[n].toString());
}
}
}
对于新活动，例如FacebookList，我们将创建以下ItemList布局：
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:orientation="vertical"
android:layout_width="fill_parent"
android:layout_height="fill_parent">
<ListView
android:id="@id/android:list"
android:layout_width="fill_parent"
android:layout_height="wrap_content"
android:layout_weight="1"
android:drawSelectorOnTop="false" />
<TextView
android:id="@id/android:empty"
android:layout_width="fill_parent"
android:layout_height="wrap_content"
android:text="No data"/>
之后，我们将创建FacebookList Activity，创建一个HashMap数组和一个适配器：
import java.util.ArrayList;
import java.util.HashMap;
import android.app.ListActivity;
import android.os.Bundle;
import android.view.View;
import android.widget.AdapterView;
import android.widget.ListAdapter;
import android.widget.ListView;
import android.widget.SimpleAdapter;
import android.widget.TextView;
import android.widget.Toast;
import android.widget.AdapterView.OnItemClickListener;
public class FacebookList extends ListActivity{
/** Called when the activity is first created. */
@Override
public void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.listplaceholder);
ArrayList<HashMap<String, String>> arl =(ArrayList<HashMap<String, String>>) getIntent().getSerializableExtra("arraylist");
System.out.println("...serialized data.."+arl);
ListAdapter adapter = new SimpleAdapter(this, arl , R.layout.list_main,
new String[] { "comments", "names" },
new int[] { R.id.item_title, R.id.item_subtitle });
ListView listView = getListView();
listView.setAdapter(adapter);
listView.setTextFilterEnabled(true);
listView.setOnItemClickListener(new OnItemClickListener() {
public void onItemClick(AdapterView<?> parent, View view,
int position, long id) {
// When clicked, show a toast with the TextView text
Toast.makeText(getApplicationContext(),
((TextView) view).getText(), Toast.LENGTH_SHORT).show();
}
});
}
}
我不知道这是否是最好的方法，但它对我有用，我希望我帮助别人！
最好的问候
