MainActivity.java:

import android.app.Activity;
import android.content.Intent;
import android.net.Uri;
import android.os.Bundle;
import android.view.Menu;
import android.view.MenuItem;
import android.view.View;
import android.view.View.OnClickListener;
import android.widget.Button;
import android.widget.EditText;

public class MainActivity extends Activity implements OnClickListener {

	private EditText numText;
	private Button button;

	@Override
	protected void onCreate(Bundle savedInstanceState) {
		super.onCreate(savedInstanceState);
		setContentView(R.layout.activity_main);
		numText = (EditText) findViewById(R.id.number);
		button = (Button) findViewById(R.id.button);
		button.setOnClickListener(this);
	}

	@Override
	public void onClick(View v) {
		// TODO Auto-generated method stub
		String number = numText.getText().toString();
		Intent intent = new Intent();
		intent.setAction(intent.ACTION_CALL);
		intent.setData(Uri.parse("tel:"+number));
		startActivity(intent);
	}
}

activity_main.xml:

<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
    xmlns:tools="http://schemas.android.com/tools"
    android:layout_width="fill_parent"
    android:layout_height="fill_parent"
    android:orientation="vertical"
    android:paddingBottom="@dimen/activity_vertical_margin"
    android:paddingLeft="@dimen/activity_horizontal_margin"
    android:paddingRight="@dimen/activity_horizontal_margin"
    android:paddingTop="@dimen/activity_vertical_margin"
    tools:context="com.example.calldemo.MainActivity" >

    <TextView
        android:layout_width="wrap_content"
        android:layout_height="wrap_content"
        android:text="输入电话号码" />

    <EditText
        android:id="@+id/number"
        android:layout_width="fill_parent"
        android:layout_height="wrap_content" />
    <Button 
        android:id="@+id/button"
        android:layout_width="wrap_content"
        android:layout_height="wrap_content"
        android:text="拨打"/>

</LinearLayout>

需要添加权限：

  <uses-permission android:name="android.permission.CALL_PHONE"/>

OK。。。
