Android 拦截修改电话号码

第一步：把要添加的号码存储到config.xml文件

public class IPActivity extends Activity {    @Override    protected void onCreate(Bundle savedInstanceState) {        super.onCreate(savedInstanceState);        setContentView(R.layout.activity_main);        Button button = new Button(this);        final EditText editText = new EditText(this);        button.setOnClickListener(new OnClickListener() {            @Override            public void onClick(View v) {                SharedPreferences sp = getSharedPreferences("config" ,Context.MODE_PRIVATE);                sp.edit().putString("ip", editText.getText().toString().trim()).commit();            }        });    }}

第二步：使用广播拦截电话号码，并修改

public class IPBrocastReceiver extends BroadcastReceiver {    @Override    public void onReceive(Context context, Intent intent) {        String resultData = getResultData();        SharedPreferences sp = context.getSharedPreferences("config", Context.MODE_PRIVATE);        String ip = sp.getString("ip", null);        setResultData(ip + resultData);    }}
