使用Intent打开一个Dial界面

1.新建项目：

2.打开main.xml删除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.编辑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:[phone]"));
       // DialIntent.setFlags(Intent.FLAG_ACTIVITY_NEW_TASK);
        DialIntent.setFlags(Intent.FLAG_ACTIVITY_NO_HISTORY);
        startActivity(DialIntent);
    }
}
