android 电话拨号器

电话拨号器源码如下

权限配制文件 AndroidManifest.xml

<manifest xmlns:android=“http://schemas.android.com/apk/res/android”

package="com.example.phone"
android:versionCode="1"
android:versionName="1.0" >

<uses-sdk
    android:minSdkVersion="8"
    android:targetSdkVersion="15" />

<application
    android:icon="@drawable/ic_launcher"
    android:label="@string/app_name"
    android:theme="@style/AppTheme" >
    <activity
        android:name=".MainActivity"
        android:label="@string/title_activity_main" >
        <intent-filter>
            <action android:name="android.intent.action.MAIN" />

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

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

此文件也是布局管理用与下面文件配套使用string.xml

<string name="app_name">电话拨号器</string>
<string name="menu_settings">Settings</string>
<string name="title_activity_main">电话拨号器</string>
<string name="mobile">请输入电话号码</string>
<string name="button">拨号</string>

布局管理 activity_main.xml
<RelativeLayout 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" >

<TextView
    android:layout_width="fill_parent"
    android:layout_height="wrap_content"
    android:text="@string/mobile" />

<EditText

    android:layout_width="fill_parent"
    android:layout_height="wrap_content" 
    android:id="@+id/mobile"/>

<Button
    android:id="@+id/button"
    android:layout_width="wrap_content"
    android:layout_height="wrap_content"
    android:layout_alignParentLeft="true"
    android:layout_below="@+id/mobile"
    android:text="@string/button" />
