Android之監(jiān)聽來電，權(quán)限管理， 多語言方案，雙卡撥號

有關(guān)權(quán)限管理

Anroid6.0以下， 權(quán)限申明后即可獲?。▏a(chǎn)定制系統(tǒng)除外）
在manifest文件里聲明權(quán)限：

//電話相關(guān)權(quán)限
<uses-permission android:name="android.permission.READ_PHONE_STATE"/>
<uses-permission android:name="android.permission.PROCESS_OUTGOING_CALLS"/>
<uses-permission android:name="android.permission.CALL_PHONE"/>

6.0以上不僅要聲明，還需運(yùn)行時(shí)獲取。
步驟大概如下：

已打電話權(quán)限為例說明（一般情況）：

    private void checkAndRquestCallPermission() {
        if (ActivityCompat.checkSelfPermission(this, Manifest.permission.CALL_PHONE) != PackageManager.PERMISSION_GRANTED) {
            Log.d(TAG, "checkCallPermission: " + "沒有打電話權(quán)限");
            ActivityCompat.requestPermissions(this, new String[]{Manifest.permission.CALL_PHONE}, 1);// 1:code
        }
    }

    //重載activity的onRequestPermissionsResult方法
    @Override
    public void onRequestPermissionsResult(int requestCode, @NonNull String[] permissions, @NonNull int[] grantResults) {
        if (requestCode == 1) {
            if (1 == grantResults.length && PackageManager.PERMISSION_GRANTED == grantResults[0]) {
                Log.d(TAG, "onRequestPermissionsResult: " + "已獲?。? + permissions[0] + " 權(quán)限");
            }     
        } else {
            super.onRequestPermissionsResult(requestCode, permissions, grantResults);
        }
    }

對shouldShowRequestPermissionRationale方法的補(bǔ)充說明：
在請求權(quán)限時(shí)，這個(gè)函數(shù)用來可以用來給用戶提示為什么需要權(quán)限（用戶沒有勾選不再提示按鈕，第一次請求或是拒絕后返回ture）：

    private void checkAndRquestCallPermission() {
        if (ActivityCompat.checkSelfPermission(this, Manifest.permission.CALL_PHONE) != PackageManager.PERMISSION_GRANTED) {
            Log.d(TAG, "checkCallPermission: " + "沒有電話權(quán)限");
            if (ActivityCompat.shouldShowRequestPermissionRationale(this, Manifest.permission.CALL_PHONE)) {
                Log.d(TAG, "checkCallPermission: " + "need phone permission");
                //彈出對話框，提示用戶允許或者拒絕，允許則請求權(quán)限
            }
            //此處默認(rèn)允許
            ActivityCompat.requestPermissions(this, new String[]{Manifest.permission.CALL_PHONE}, 1);// 1:code
        }
    }

    @Override
    public void onRequestPermissionsResult(int requestCode, @NonNull String[] permissions, @NonNull int[] grantResults) {
        if (requestCode == 1) {
            if (1 == grantResults.length && PackageManager.PERMISSION_GRANTED == grantResults[0]) {
                Log.d(TAG, "onRequestPermissionsResult: " + "以獲?。? + permissions[0] + " 權(quán)限");
            }
            else {
                if (ActivityCompat.shouldShowRequestPermissionRationale(this, Manifest.permission.CALL_PHONE)) {
//                  //用戶沒有勾選不再提示，并拒絕
                    Log.d(TAG, "onRequestPermissionsResult: " + "refuse one time");
                } else {
//                    用戶勾選提示并拒絕
                    Log.d(TAG, "onRequestPermissionsResult: " + "refuse forever");
                    //跳轉(zhuǎn)權(quán)限設(shè)置頁
                }
            }
        } else {
            super.onRequestPermissionsResult(requestCode, permissions, grantResults);
        }
    }

根據(jù)測試，小米機(jī)型貌似沒有可勾選功能，一次拒絕默認(rèn)永遠(yuǎn)拒絕。下次申請到權(quán)限設(shè)置頁。
（國產(chǎn)機(jī)型區(qū)分對待）

來電監(jiān)聽和撥打監(jiān)聽

簡單介紹此功能的實(shí)現(xiàn)
在有電話權(quán)限的前提下
在有電話權(quán)限的前提下

功能比較簡單，看代碼就行：
繼承BroadcastReceiver類處理即可：

public class PhoneReceiver extends BroadcastReceiver {
    private static final String TAG = "PhoneReceiver";
    private boolean mInComingFlag = false;
    private static String ACTION_NEW_INCOMMING_CALL = "android.intent.action.PHONE_STATE";
    private PhoneStateListener listen = new PhoneStateListener(){
        @Override
        public void onCallStateChanged(int state, String incomingNumber) {
            super.onCallStateChanged(state, incomingNumber);
            switch (state) {
                case TelephonyManager.CALL_STATE_RINGING:
                    //電話打進(jìn)響鈴中，電話打出沒有此狀態(tài)
                    mInComingFlag = true;
                    Log.d(TAG, "onCallStateChanged: " + incomingNumber);
                    break;
                case TelephonyManager.CALL_STATE_IDLE:
                    //掛斷電話
                    if (mInComingFlag) {
                        Log.d(TAG, "onCallStateChanged: " + "call hang up");
                    }
                    break;
                case TelephonyManager.CALL_STATE_OFFHOOK:
                    //電話接聽
                    if (mInComingFlag) {
                        Log.d(TAG, "onCallStateChanged: " + "接聽電話：" + incomingNumber);
                    }
            }
        }
    };

    @Override
    public void onReceive(Context context, Intent intent) {
        if (intent.getAction().equals(Intent.ACTION_NEW_OUTGOING_CALL)) {
            //電話打出
            mInComingFlag = false;
            String phoneNumber = intent.getStringExtra(Intent.EXTRA_PHONE_NUMBER);
            Log.d(TAG, "onReceive: " + "call phoneNumber：" + phoneNumber);
        }
        if (intent.getAction().equals(ACTION_NEW_INCOMMING_CALL)) {
            //電話打進(jìn)
            TelephonyManager tm = (TelephonyManager) context.getSystemService(Context.TELEPHONY_SERVICE);
            tm.listen(listen, PhoneStateListener.LISTEN_CALL_STATE);

        }
    }
}

接著在manifest聲明該receiver和需要過濾的廣播

        <receiver android:name=".phone.PhoneReceiver"
                  android:exported="true">
            <intent-filter>
                <action android:name="android.intent.action.NEW_OUTGOING_CALL"/>
                <action android:name="android.intent.action.PHONE_STATE"/>
                <action android:name="android.intent.action.MY_SELF_RECEIVER"/>
            </intent-filter>
        </receiver>

自定義廣播發(fā)送并接收（同上）

                //發(fā)送自定義廣播，PhoneReceiver接收
                Intent intent = new Intent(ACTION);
                intent.putExtra("Msg", "helloReceiver");
                sendBroadcast(intent);

多語言方案實(shí)現(xiàn)

    //選擇語言并保存狀態(tài)
    private void changeLanguage() {
        //彈出對話框或者其他方式選擇語言，并持久化保存到本地
        AlertDialog.Builder builder = new AlertDialog.Builder(this);
        builder.setSingleChoiceItems(new String[]{"auto", "English", "簡體中文"},
                getSharedPreferences("language", Context.MODE_PRIVATE).getInt("language", 0),
                new DialogInterface.OnClickListener() {
                    @Override
                    public void onClick(DialogInterface dialog, int which) {
                        SharedPreferences preferences = getSharedPreferences("language", Context.MODE_PRIVATE);
                        SharedPreferences.Editor editor = preferences.edit();
                        Log.d(TAG, "onClick: " + which);
                        //保存設(shè)置
                        editor.putInt("language", which);
                        editor.apply();
                        dialog.dismiss();

                        Intent intent = new Intent(MultiLanguageActivity.this, MultiLanguageActivity.class);
                        //重新打開一個(gè)返回棧并清除前者
                        intent.setFlags(Intent.FLAG_ACTIVITY_NEW_TASK | Intent.FLAG_ACTIVITY_CLEAR_TASK);
                        startActivity(intent);
                    }
                });
        AlertDialog dialog = builder.create();
        dialog.show();
    }

    //加載所保存的語言
    private void setLanguage() {
        SharedPreferences preferences = getSharedPreferences("language", Context.MODE_PRIVATE);
        int language = preferences.getInt("language", 0);

        Resources resources  = getResources();
        DisplayMetrics dispalyMetRics = resources.getDisplayMetrics();
        Configuration configuration = resources.getConfiguration();
        switch (language) {
            case 0:
                configuration.setLocale(Locale.getDefault());
                break;
            case 1:
                configuration.setLocale(Locale.ENGLISH);
                break;
            case 2:
                configuration.setLocale(Locale.CHINESE);
                break;
        }
        // FIXME: 2017/6/5
        resources.updateConfiguration(configuration, dispalyMetRics);
    }

添加語言文件strings：

因?yàn)閷ctionBar不起作用，因此需要調(diào)用以下方法設(shè)置title顯示。

getSupportActionBar().setTitle(R.string.app_name);

雙卡雙待手機(jī)撥打電話（暫無監(jiān)聽雙卡雙待電話接聽情況）

判斷當(dāng)前sim使用情況：

    @RequiresApi(api = Build.VERSION_CODES.LOLLIPOP_MR1)
    private int checkDualSim() {
        int simNumber = 0;
        SubscriptionManager sm = SubscriptionManager.from(this);
        List<SubscriptionInfo> subs = sm.getActiveSubscriptionInfoList();
        if (subs == null) {
            d(TAG, "checkDualSim: " + "no sim");
            return simNumber;
        }
        if (subs.size() > 1) {
            simNumber = 2;
            d(TAG, "checkDualSim: " + "two sims");
        } else {
            d(TAG, "checkDualSim: " + "one sim");
            simNumber = 1;
        }
        for (SubscriptionInfo s: subs) {
            d(TAG, "checkDualSim: " + "simInfo:" + subs.toString());
        }
        return simNumber;
    }

//根據(jù)上述情況，初始化UI和撥打電話，尤其注意sim2的打電話情況
    @RequiresApi(api = Build.VERSION_CODES.M)
    private void callPhone(boolean isDualSim) {
        if (ActivityCompat.checkSelfPermission(this, Manifest.permission.CALL_PHONE) != PackageManager.PERMISSION_GRANTED) {
            Log.d(TAG, "callPhone: " + "no call phone permission");
            return;
        }
        String phoneNumber = mBinding.etPhoneNumber.getText().toString().trim();
        phoneNumber = TextUtils.isEmpty(phoneNumber) ? "13422284669" : phoneNumber;
        if (!isDualSim) {
            //單卡
            Intent intent = new Intent();
            intent.setAction(Intent.ACTION_CALL);
            intent.setData(Uri.parse("tel:" + phoneNumber));
            startActivity(intent);
            return;
        }
        TelecomManager telecomManager = (TelecomManager)getSystemService(Context.TELECOM_SERVICE);
        if(telecomManager != null) {
            List<PhoneAccountHandle> phoneAccountHandleList = telecomManager.getCallCapablePhoneAccounts();
            d(TAG, "callPhone: " + phoneAccountHandleList);
            d(TAG, "callPhone: " + phoneAccountHandleList.get(1).toString());
            Intent intent = new Intent();
            intent.setAction(Intent.ACTION_CALL);
            intent.setData(Uri.parse("tel:" + phoneNumber));
            intent.putExtra(TelecomManager.EXTRA_PHONE_ACCOUNT_HANDLE, phoneAccountHandleList.get(1));
            startActivity(intent);
        }
    }
