Android之实现手机号码拦截

1.布局

<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"    xmlns:tools="http://schemas.android.com/tools"    android:id="@+id/activity_main"    android:layout_width="match_parent"    android:layout_height="match_parent"    android:orientation="vertical">    <EditText        android:layout_width="match_parent"        android:layout_height="wrap_content"        android:id="@+id/ma_itc_et"         />    <Button        android:layout_width="match_parent"        android:layout_height="wrap_content"        android:text="确认"        android:onClick="yes"/>LinearLayout>

2.java代码

public class MainActivity extends AppCompatActivity {    private EditText ma_itc_et;    private String number;    @Override    protected void onCreate(Bundle savedInstanceState) {        super.onCreate(savedInstanceState);        setContentView(R.layout.activity_main);        ma_itc_et = (EditText) findViewById(R.id.ma_itc_et);        //从SharedPreferences获取保存号码的路径        SharedPreferences spe = this.getSharedPreferences("yyy", this.MODE_PRIVATE);        //根据路径来得到取出保存的号码        String data =spe.getString("code", "");        ma_itc_et.setText(data);    }    public void yes(View view) {        number = ma_itc_et.getText().toString();        //把输入框里面的值通过SharedPreferences保存,第一个参数是取个文件名        SharedPreferences.Editor editor = getSharedPreferences("yyy", MODE_WORLD_WRITEABLE).edit();        //第一个参数是键，第二个是电话号码        editor.putString("code", number);        editor.commit();    }}

3.注册一个广播

public class MyphoneState extends BroadcastReceiver {    @Override    public void onReceive(Context context, Intent intent) {        if ("android.intent.action.PHONE_STATE".equals(intent.getAction())) {            String phone = intent.getStringExtra("incoming_number");            //从SharedPreferences获取保存号码的路径            SharedPreferences spe = context.getSharedPreferences("yyy", context.MODE_PRIVATE);            //根据路径来得到取出保存的号码            String data =spe.getString("code", "");            //把来电的号码跟你输入的号码判断            //其实可以不用判断也不用页面那样的话任何来电都会挂断            if (phone.equals(data)) {                TelephonyManager telephonyManager = (TelephonyManager) context.getSystemService(context.TELEPHONY_SERVICE);                int state = telephonyManager.getCallState();                switch (state) {                    //来电状态                    case TelephonyManager.CALL_STATE_RINGING:                        //得到TelephonyManager的Class对象                        Class telephonyManagerClass = TelephonyManager.class;                        try {                            //得到TelephonyManager.getITelephony方法的Method对象                            Method method = telephonyManagerClass.getDeclaredMethod("getITelephony", null);                            //允许访问私有方法                            method.setAccessible(true);                            //调用getITelephony方法发挥ITelephony对象                            ITelephony telephony = (ITelephony) method.invoke(telephonyManager, null);                            //挂断电话                            telephony.endCall();                        } catch (Exception e) {                            e.printStackTrace();                        }                        break;                    //通话状态                    case TelephonyManager.CALL_STATE_OFFHOOK:                        break;                    //挂断状态                    case TelephonyManager.CALL_STATE_IDLE:                        break;                }            }        }    }}

4.在AndroidManifest文件添加权限和配置广播

    <uses-permission android:name="android.permission.READ_PHONE_STATE">uses-permission>        <uses-permission android:name="android.permission.CALL_PHONE">uses-permission><receiver android:name=".MyphoneState">            <intent-filter>                <action android:name="android.intent.action.PHONE_STATE">action>            intent-filter>        receiver>

5.在项目下建个aidl文件夹，把这两个文件夹复制进去
