分类 Android 基础入门教程

本节引言:


1.获得TelephonyManager的服务对象

TelephonyManager tManager = (TelephonyManager)getSystemService(Context.TELEPHONY_SERVICE);


2.用法示例


1)调用拨号器拨打电话号码

Uri uri=Uri.parse("tel:"+电话号码);    
Intent intent=new Intent(Intent.ACTION_DIAL,uri);    
startActivity(intent);  

2)获取Sim卡信息与网络信息

        android:textSize="20sp" />

</LinearLayout>

MainActivity.java:

public class MainActivity extends AppCompatActivity {

    private TextView tv_phone1;
    private TextView tv_phone2;
    private TextView tv_phone3;
    private TextView tv_phone4;
    private TextView tv_phone5;
    private TextView tv_phone6;
    private TextView tv_phone7;
    private TextView tv_phone8;
    private TextView tv_phone9;
    private TelephonyManager tManager;
    private String[] phoneType = {"未知","2G","3G","4G"};
    private String[] simState = {"状态未知","无SIM卡","被PIN加锁","被PUK加锁",
            "被NetWork PIN加锁","已准备好"};

    @Override
    protected void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.activity_main);
        //①获得系统提供的TelphonyManager对象的实例
        tManager = (TelephonyManager) getSystemService(Context.TELEPHONY_SERVICE);
        bindViews();
    }

    private void bindViews() {
        tv_phone1 = (TextView) findViewById(R.id.tv_phone1);
        tv_phone2 = (TextView) findViewById(R.id.tv_phone2);
        tv_phone3 = (TextView) findViewById(R.id.tv_phone3);
        tv_phone4 = (TextView) findViewById(R.id.tv_phone4);
        tv_phone5 = (TextView) findViewById(R.id.tv_phone5);
        tv_phone6 = (TextView) findViewById(R.id.tv_phone6);
        tv_phone7 = (TextView) findViewById(R.id.tv_phone7);
        tv_phone8 = (TextView) findViewById(R.id.tv_phone8);
        tv_phone9 = (TextView) findViewById(R.id.tv_phone9);

        tv_phone1.setText("设备编号:" + tManager.getDeviceId());
        tv_phone2.setText("软件版本:" + (tManager.getDeviceSoftwareVersion()!= null?
                tManager.getDeviceSoftwareVersion():"未知"));
        tv_phone3.setText("运营商代号:" + tManager.getNetworkOperator());
        tv_phone4.setText("运营商名称:" + tManager.getNetworkOperatorName());
        tv_phone5.setText("网络类型:" + phoneType[tManager.getPhoneType()]);
        tv_phone6.setText("设备当前位置:" + (tManager.getCellLocation() != null ? tManager
                .getCellLocation().toString() : "未知位置"));
        tv_phone7.setText("SIM卡的国别:" + tManager.getSimCountryIso());
        tv_phone8.setText("SIM卡序列号:" + tManager.getSimSerialNumber());
        tv_phone9.setText("SIM卡状态:" + simState[tManager.getSimState()]);
    }
}

对了,别忘了在AndroidManifest.xml中加上权限哦!

<!-- 添加访问手机位置的权限 -->
<uses-permission android:name="android.permission.ACCESS_COARSE_LOCATION"/>
<!-- 添加访问手机状态的权限 -->
<uses-permission android:name="android.permission.READ_PHONE_STATE"/>

对了可能你想获取网络制式,而非普通的2G,3G,4G这样,其实我们可以到TelephonyManager类的源码里:

10.1 TelephonyManager(电话管理器)

我们可以根据这个networkType的值,判断不同的网络制式,比如,如果networkType == 1 那个是GPRS这种制式的~而这个networkType的值可以通过

10.1 TelephonyManager(电话管理器)

即这个getNetworkType()方法获得!好了,就这么简单,可以像上面列好一个数组然后根据 不同的下标显示不同的值! 对了,还有Sim卡状态的,字符串数组中的值,都可以到源码中看:

10.1 TelephonyManager(电话管理器)

其他的可自行探索~


3)获取手机的信号强度

手机获取信号强度代码示例

dBm =-113+2*asu这是一个固定公式,asu(独立信号单元)

运行效果图

10.1 TelephonyManager(电话管理器)

实现代码

MainActivity.java

public class MainActivity extends AppCompatActivity {

    private TextView tv_rssi;
    private MyPhoneStateListener mpsListener;
    private TelephonyManager tManager;


    @Override
    protected void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.activity_main);
        tManager = ((TelephonyManager)getSystemService(Context.TELEPHONY_SERVICE));
        tv_rssi = (TextView) findViewById(R.id.tv_rssi);
        mpsListener  = new MyPhoneStateListener();
        tManager.listen(mpsListener,290);
    }

    private class MyPhoneStateListener extends PhoneStateListener {
        private int asu = 0,lastSignal = 0;
        @Override
        public void onSignalStrengthsChanged(SignalStrength signalStrength) {
            asu = signalStrength.getGsmSignalStrength();
            lastSignal = -113 + 2 * asu;
            tv_rssi.setText("当前手机的信号强度:" + lastSignal + " dBm" );
            super.onSignalStrengthsChanged(signalStrength);
        }
    }
}

另外因为笔者的卡都是移动卡,联通和电信的不知道,但是从源码里看到这样几个API:

  • getEvdoDbm():电信3G
  • getCdmaDbm():联通3G
  • getLteDbm():4G

这些应该是可以直接获得dBm信号强度的,有条件的可以试试~

还有,别忘记加上权限了哦!

<!-- 添加访问手机状态的权限 -->
 <uses-permission android:name="android.permission.READ_PHONE_STATE"/>
 

4)监听手机的所有来电

代码解析:

实现代码

MainActivity.java

public class MainActivity extends Activity  
{  
    TelephonyManager tManager;  
  
    @Override  
    public void onCreate(Bundle savedInstanceState)  
    {  
        super.onCreate(savedInstanceState);  
        setContentView(R.layout.main);  
        // 取得TelephonyManager对象  
        tManager = (TelephonyManager)   
            getSystemService(Context.TELEPHONY_SERVICE);  
        // 创建一个通话状态监听器  
        PhoneStateListener listener = new PhoneStateListener()  
        {  
            @Override  
            public void onCallStateChanged(int state, String number)  
            {  
                switch (state)  
                {  
                // 无任何状态  
                    case TelephonyManager.CALL_STATE_IDLE:  
                        break;  
                    case TelephonyManager.CALL_STATE_OFFHOOK:  
                        break;  
                    // 来电铃响时  
                    case TelephonyManager.CALL_STATE_RINGING:  
                        OutputStream os = null;  
                        try  
                        {  
                            os = openFileOutput("phoneList", MODE_APPEND);  
                        }  
                        catch (FileNotFoundException e)  
                        {  
                            e.printStackTrace();  
                        }  
                        PrintStream ps = new PrintStream(os);  
                        // 将来电号码记录到文件中  
                        ps.println(new Date() + " 来电:" + number);  
                        ps.close();  
                        break;  
                    default:  
                        break;  
                }  
                super.onCallStateChanged(state, number);  
            }  
        };  
        // 监听电话通话状态的改变  
        tManager.listen(listener, PhoneStateListener.LISTEN_CALL_STATE);  
    }  
}  

运行结果

注意!要让这个程序位于前台哦!用另一个电话拨打该电话,接着就可以在DDMS的file Explorer的应用 对应包名的files目录下看到phoneList的文件了,我们可以将他导出到电脑中打开,文件的大概内容如下:

THR Oct 30 12:05:48 GMT 2014 来电: 137xxxxxxx

对了,别忘了权限!

<!-- 授予该应用读取通话状态的权限 -->  
<uses-permission android:name="android.permission.READ_PHONE_STATE"/>  

5)黑名单来电自动挂断

这里给出的是简单的单个号码的拦截,输入号码,点击屏蔽按钮后,如果此时屏蔽的电话呼入的话; 直接会挂断,代码还是比较简单的,下面粘一下,因为用的模拟器是Genymotion,所以就不演示 程序运行后的截图了!

MainActivity.java

public class MainActivity extends Activity {  
  
    private TelephonyManager tManager;  
    private PhoneStateListener pListener;  
    private String number;  
    private EditText locknum;  
    private Button btnlock;  
      
    public class PhonecallListener extends PhoneStateListener  
    {  
        @Override  
        public void onCallStateChanged(int state, String incomingNumber) {  
            switch(state)  
            {  
            case TelephonyManager.CALL_STATE_IDLE:break;  
            case TelephonyManager.CALL_STATE_OFFHOOK:break;  
            //当有电话拨入时  
            case TelephonyManager.CALL_STATE_RINGING:  
                if(isBlock(incomingNumber))  
                {  
                    try  
                    {  
                        Method method = Class.forName("android.os.ServiceManager")  
                                .getMethod("getService", String.class);  
                        // 获取远程TELEPHONY_SERVICE的IBinder对象的代理  
                        IBinder binder = (IBinder) method.invoke(null,  
                            new Object[] { TELEPHONY_SERVICE });  
                        // 将IBinder对象的代理转换为ITelephony对象  
                        ITelephony telephony = ITelephony.Stub.asInterface(binder);  
                        // 挂断电话  
                        telephony.endCall();  
                    }catch(Exception e){e.printStackTrace();}  
                }  
                break;  
            }  
            super.onCallStateChanged(state, incomingNumber);  
        }  
    }  
      
      
    @Override  
    protected void onCreate(Bundle savedInstanceState) {  
        super.onCreate(savedInstanceState);  
        setContentView(R.layout.activity_main);  
          
        locknum = (EditText) findViewById(R.id.locknum);  
        btnlock = (Button) findViewById(R.id.btnlock);  
          
        //获取系统的TelephonyManager管理器  
        tManager = (TelephonyManager) getSystemService(TELEPHONY_SERVICE);  
        pListener = new PhoneStateListener();  
        tManager.listen(pListener, PhoneStateListener.LISTEN_CALL_STATE);  
          
        btnlock.setOnClickListener(new OnClickListener() {  
              
            @Override  
            public void onClick(View v) {  
                number = locknum.getText().toString();                
            }  
        });  
          
    }  
      
    public boolean isBlock(String phone)  
    {  
        if(phone.equals(number))return true;  
        return false;  
    }  
}
