Android拨号键盘增加魔力爱心数字

目的：在拨号键盘输入 *#*#5201314#*#* 启动自定义的某个（隐藏）应用，大胆说出你的爱！

1. 修改Android源码dialer 相关代码，自定义android_secret_code并在afterTextchanged函数中发出处理广播：

vimpackages/apps/Dialer/src/com/android/dialer/dialpad/DialpadFragment.java

+ private final String LOVEU = "*#5201314#*";

@Override

public void afterTextChanged(Editable input) {

+ if(LOVEU.equals(input.toString())){

+ startLove();

+ mDigits.getText().clear();

+ }

+ // After user put the number do it

+ private void startLove(){

+ Intent intent = new Intent();

+ intent.setAction("com.ckt.cxuef.loveu");

+ intent.setFlags(Intent.FLAG_ACTIVITY_NEW_TASK);

+ try{

+ // Call theReceiver

+ startActivity(intent);

+ }catch(ActivityNotFoundException ane){

+ ane.printStackTrace();

+ }

2. 修改Android工程App的AndroidManifest.xml ,定义接收广播：

<receiver

android:name=".LoveUReceiver"

android:exported="true" >

<intent-filter>

<data

android:host="5201314"

android:scheme="android_secret_code" />

</intent-filter>

</receiver>

3. 增加Android工程App的XXXReceiver,继承并实现广播BroadcastReceiver：

public final classLoveUReceiverextends BroadcastReceiver {

private static final String TAG = "EIROT_SECRET_CODE";

private static final String SECRET_CODE_ACTION = "android.provider.Telephony.SECRET_CODE";

// process *#*#5201314#*#*

private final Uri mLoveUri = Uri.parse("android_secret_code://5201314");

@Override

public void onReceive(Context context, Intent intent) {

if (intent.getAction() == null) {

log.i(TAG, "Null action");

return;

}

if (intent.getAction().equals(SECRET_CODE_ACTION)) {

Uri uri = intent.getData();

log.i(TAG, "getIntent success in if");

if (uri.equals(mLoveUri)) {

Intent intentLoveU = new Intent(context, LoveUActivity.class);

intentLoveU.setFlags(Intent.FLAG_ACTIVITY_NEW_TASK);

log.i(TAG, "Before start LoveU activity");

context.startActivity(intentLoveU);

} else {

log.i(TAG, "No matched URI!");

}

} else {

log.i(TAG, "Not SECRET_CODE_ACTION!");

}

4. 定义Android工程App的XXXActivity，好戏从这里才刚刚开始哦！
