1.新建項目：

2.打開main.xml刪除TextView控件
? 如：

    <?xml version="1.0" encoding="utf-8"?>
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
    android:orientation="vertical"
    android:layout_width="fill_parent"
    android:layout_height="fill_parent"
    >

</LinearLayout>
  

3.編輯AndroidPhoneDialer.java

    package android_programmer_guide.androidphonedialer;

import android.app.Activity;
import android.os.Bundle;
import android.content.Intent;
import android.net.Uri;

public class AndroidPhoneDialer extends Activity {
    /** Called when the activity is first created. */
    @Override
    public void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.main);
        Intent DialIntent = new Intent(Intent.ACTION_DIAL,Uri.parse("tel:13632783420"));
       // DialIntent.setFlags(Intent.FLAG_ACTIVITY_NEW_TASK);
        DialIntent.setFlags(Intent.FLAG_ACTIVITY_NO_HISTORY);
        startActivity(DialIntent);
    }
}
  

使用Intent打開一個Dial界面
