android打电话

   拨打电话的关键有两个方面，首先看，要在AndroidManifest中添加user-permission,并声明Android.permission.CALL_PHONE权限。由于拨打电话属于手机底层的服务，和用户隐私，通话费用等信息都息息相关，因此，程序必须取得相关权限。

      代码：

package org.hwq.ex5_phone;

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

public class Main extends Activity {
	Button b;
    /** Called when the activity is first created. */
    @Override
    public void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.main);
        b = (Button) findViewById(R.id.button1);
        b.setOnClickListener(new Button.OnClickListener(){

			@Override
			public void onClick(View arg0) {
				// TODO Auto-generated method stub
				Intent intent = new Intent(Intent.ACTION_CALL,Uri.parse("tel:10086"));
				startActivity(intent);
			}
        	
        });
    }
}

      AndroidManifest中添加打电话权限

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

<?xml version="1.0" encoding="utf-8"?>
<manifest xmlns:android="http://schemas.android.com/apk/res/android"
    package="org.hwq.ex5_phone"
    android:versionCode="1"
    android:versionName="1.0" >

    <uses-sdk android:minSdkVersion="10" />
    <uses-permission android:name="android.permission.CALL_PHONE"/>

    <application
        android:icon="@drawable/ic_launcher"
        android:label="@string/app_name" >
        <activity
            android:name=".Main"
            android:label="@string/app_name" >
            <intent-filter>
                <action android:name="android.intent.action.MAIN" />

                <category android:name="android.intent.category.LAUNCHER" />
            </intent-filter>
        </activity>
    </application>

</manifest>
