        e.printStackTrace();  
      }  
    }  
  }   
}  </pre> 



 
  二、activity使用  
   

import android.app.Activity;

import android.os.Bundle;

import android.view.Menu;

import android.view.View;

import android.view.View.OnClickListener;

import android.widget.Button;

import android.widget.EditText;

import android.widget.TextView;
public class MainActivity extends Activity implements OnClickListener {
private TextView teleStartTime, teleEndTime;

  private Button teleButton;

  private TeleInterface teleInterface;

  private TeleHandler teleHandler;

  private EditText telNo;
@Override

  protected void onCreate(Bundle savedInstanceState) {

    super.onCreate(savedInstanceState);

    setContentView(R.layout.activity_main);

    initView();

    teleHandler = new TeleHandler(this, teleStartTime, teleEndTime);

    teleInterface = new TeleInterface(this, teleHandler);

    teleInterface.teleListen();

  }
private void initView() {

    teleStartTime = (TextView) findViewById(R.id.teleStartTime);

    teleEndTime = (TextView) findViewById(R.id.teleEndTime);

    teleButton = (Button) findViewById(R.id.teleButton);

    telNo = (EditText) findViewById(R.id.telno);

    teleButton.setOnClickListener(this);

  }
@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;

  }
@Override

  public void onClick(View v) {

    switch (v.getId()) {

      case R.id.teleButton:

            if(!telNo.getText().toString().trim().equals("")){

                 teleInterface.Call(telNo.getText().toString().trim());

            }else{

                 teleInterface.Call("10010");

            }

        try {  

//              Thread.sleep(5000);

//              teleInterface.sendDTMF("1".toCharArray()[0]);

              teleInterface.endCall();

            } catch (Exception e) {

              // TODO Auto-generated catch block

              e.printStackTrace();

            }

            break;

  default:  
    break;  
}  

}
}  </pre> 

 三、布局配置文件
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android&quot;

    xmlns:tools="http://schemas.android.com/tools&quot;

    android:layout_width="fill_parent"

    android:layout_height="wrap_content"

    android:orientation="vertical"

    tools:context=".MainActivity" >

<EditText   
    android:layout_width="fill_parent"  
    android:layout_height="wrap_content"  
    android:id="@+id/telno"  
    android:numeric="integer"  
    android:hint="電話號碼"/>  

<Button  
    android:id="@+id/teleButton"  
    android:layout_width="wrap_content"  
    android:layout_height="wrap_content"  
    android:text="撥號" />  

<TextView  
    android:layout_width="wrap_content"  
    android:layout_height="wrap_content"  
    android:text="通話時間：" />  

<TextView  
    android:id="@+id/teleStartTime"  
    android:layout_width="wrap_content"  
    android:layout_height="wrap_content" />  

<TextView  
    android:layout_width="wrap_content"  
    android:layout_height="wrap_content"  
    android:text="結束時間：" />  

<TextView  
    android:id="@+id/teleEndTime"  
    android:layout_width="wrap_content"  
    android:layout_height="wrap_content" />  


</LinearLayout></pre>
