1、界面效果图

2、AndroidManifest.xml

<?xml version="1.0" encoding="utf-8"?>
<manifest xmlns:android="http://schemas.android.com/apk/res/android"
      package="com.tjp"
      android:versionCode="1"
      android:versionName="1.0">
    <uses-sdk android:minSdkVersion="7" />

    <application android:icon="@drawable/congsmall" android:label="@string/app_name">
        <activity android:name=".PhoneActivity"
                  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>
    <uses-permission android:name="android.permission.CALL_PHONE"/>
</manifest>

3、界面代码

<?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"
    >
<TextView  
    android:layout_width="fill_parent" 
    android:layout_height="wrap_content" 
    android:text="@string/mobilelable" 
    />
<EditText
    android:layout_width="fill_parent"
    android:layout_height="wrap_content"
    android:id="@+id/mobile"
/>
<Button
    android:layout_width="wrap_content"
    android:layout_height="wrap_content"
    android:text="@string/buttonlabl"
    android:id="@+id/btncall"
/>
</LinearLayout>

4、界面值定义strings.xml

<?xml version="1.0" encoding="utf-8"?>
<resources>
    <string name="mobilelable">请输入手机号码</string>
    <string name="app_name">电话拨号器</string>
    <string name="buttonlabl">拨打</string>
</resources>

5、activity

package com.tjp;

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

public class PhoneActivity extends Activity {
   
    private EditText mobile;
    
    @Override
    public void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.main);
        Button btncall=(Button)this.findViewById(R.id.btncall);
        mobile=(EditText)this.findViewById(R.id.mobile);
        btncall.setOnClickListener(new  View.OnClickListener(){  //匿名内部类
            @Override
            public void onClick(View v) {
                String mobileText=mobile.getText().toString();
                Intent intent=new Intent(Intent.ACTION_CALL,Uri.parse("tel:"+mobileText));//拨打电话
                startActivity(intent);
            }
            
        });
    }
}
