我正在开发一个 android 应用程序,它连接到 omegle 服务器,收到来自陌生人的消息,因为有一个完整的 API,有一个方法 send(message) 可以向服务器发送消息,但它可以用作session.send(mesage),因为 session 是保存 omeglesession 值的变量,现在这是我的代码 -->
MainActivity.java
package com.example.com.omegle.test;
import org.nikki.omegle.Omegle;
import org.nikki.omegle.core.OmegleException;
import org.nikki.omegle.core.OmegleMode;
import org.nikki.omegle.core.OmegleSession;
import org.nikki.omegle.event.OmegleEventAdaptor;
import android.app.Activity;
import android.os.AsyncTask;
import android.os.Bundle;
import android.view.View;
import android.widget.Button;
import android.widget.EditText;
import android.widget.TextView;
public class MainActivity extends Activity {
TextView txt;
Button m_btn;
EditText m_edt;
OmegleSession session;
@Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);
m_btn = (Button)findViewById(R.id.button);
m_edt = (EditText)findViewById(R.id.type);
m_btn.setOnClickListener(new View.OnClickListener() {
@Override
public void onClick(View v) {
sendIt(v);
}
});
m_btn.setClickable(false);
OmegleChat om=new OmegleChat();
om.execute();
}
protected void sendIt(View v)
{
txt.append("You: "+m_edt.getText().toString());
m_edt.setText("");
try {
this.session.send(m_edt.getText().toString());
} catch (OmegleException e) {
// TODO Auto-generated catch block
e.printStackTrace();
}
}
private class OmegleChat extends AsyncTask<Void, Void, Void> {
@Override
protected void onPreExecute() {
txt=(TextView)findViewById(R.id.omegle);
txt.append("Omegele Connection Started... \n");
}
@Override
protected void onProgressUpdate(Void... values) {
}
@Override
protected Void doInBackground(Void... arg0) {
// TODO Auto-generated method stub
OmgeleChatOn();
return null;
}
@Override
protected void onPostExecute(Void result) {
}
}
public void OmgeleChatOn()
{
Omegle omegle = new Omegle();
try {
System.out.println("Opening session...");
this.session = omegle.openSession(OmegleMode.NORMAL, new OmegleEventAdaptor() {
@Override
public void chatWaiting(OmegleSession session) {
System.out.println("Waiting for chat...");
}
@Override
public void chatConnected(OmegleSession session) {
System.out.println("You are now talking to a random stranger!");
}
@Override
public void chatMessage(final OmegleSession session, final String message) {
System.out.println("Stranger: " + message);
runOnUiThread(new Runnable() {
@Override
public void run() {
txt.append("Stranger:"+message+"\n");
m_btn.setClickable(true);
}
});
}
@Override
public void messageSent(OmegleSession session, final String string) {
System.out.println("You: " + string);
}
@Override
public void strangerDisconnected(OmegleSession session) {
System.out.println("Stranger disconnected, goodbye!");
//System.exit(0);
}
@Override
public void omegleError(OmegleSession session, String string) {
System.out.println("ERROR! " + string);
System.exit(1);
}
});
//HERE I WANT TO USE session.send(msg_from_edit_text) HOW TO DO THAT AS I HAVE A FUNCTION sendIt(v) above this method
session.send("hi",true);
} catch (OmegleException e) {
e.printStackTrace();
}
}
}
现在在上面的第 156 行 catch 你可以看到一个 session.send("hi",true); 每当我连接到服务器时,它都会向服务器发送一条消息,但我想在 Sendit(v) 方法中使用它,当用户从屏幕上按下按钮时调用该方法,以便它可以将用户定义的消息发送到服务器,但我不能这样做,因为会话变量是在 OmgeleChatOn 函数中定义的,我不能在该方法之外使用它,如何做到这一点,我尝试了很多搜索,但找到了正确的答案,请帮忙?
