Android 动态权限获取

1. 获取位置、IMEI、存储信息

1. 初始化

初始化到一个数组中，然后去注册权限

    private void initPermission() {
        List permissionList = new ArrayList<>();
        if (ContextCompat.checkSelfPermission(this, Manifest.permission.WRITE_EXTERNAL_STORAGE) != PackageManager.PERMISSION_GRANTED) {
            permissionList.add(Manifest.permission.WRITE_EXTERNAL_STORAGE);
        }

        if (ActivityCompat.checkSelfPermission(this, Manifest.permission.READ_PHONE_STATE) != PackageManager.PERMISSION_GRANTED) {
            permissionList.add(Manifest.permission.READ_PHONE_STATE);
        }

        if (ActivityCompat.checkSelfPermission(this, Manifest.permission.ACCESS_COARSE_LOCATION) != PackageManager.PERMISSION_GRANTED
                || ActivityCompat.checkSelfPermission(this, Manifest.permission.ACCESS_FINE_LOCATION) != PackageManager.PERMISSION_GRANTED) {
            permissionList.add(Manifest.permission.ACCESS_COARSE_LOCATION);
            permissionList.add(Manifest.permission.ACCESS_FINE_LOCATION);
        }

        if (!permissionList.isEmpty()) {
            ActivityCompat.requestPermissions(mActivity, permissionList.toArray(new String[permissionList.size()]), 1);
        } else {}
    }

2. 接收回调

重写 onRequestPermissionsResult() 方法，监测注册的权限

    @Override
    public void onRequestPermissionsResult(int requestCode, @NonNull String[] permissions, @NonNull int[] grantResults) {
        super.onRequestPermissionsResult(requestCode, permissions, grantResults);
        int locationFlags = 0;
        if (requestCode == REQUEST_PERMISSION_LOCATION) {

            for (int i = 0; i < permissions.length; i++) {
                LUtil.i("onRequestPermissionsResult null : " + requestCode + ", str :" + permissions.length + ", con :" + permissions[i]);
                if (permissions[i].equals(Manifest.permission.READ_PHONE_STATE)) {
                    if (grantResults[i] != -1) {
                        initDeviceID();
                    }
                }
                if (permissions[i].equals(Manifest.permission.ACCESS_COARSE_LOCATION)) {
                    if (grantResults[i] != -1) {
                        locationFlags += 1;
                    }
                }
                if (permissions[i].equals(Manifest.permission.ACCESS_FINE_LOCATION)) {
                    if (grantResults[i] != -1) {
                        locationFlags += 1;
                    }
                }
            }

            if (locationFlags == 2) {
                getLocation(true);
            }
        }
    }

3. 具体实现

1. 获取位置信息

    private void initLocation() {
        if (ActivityCompat.checkSelfPermission(this, Manifest.permission.ACCESS_COARSE_LOCATION) != PackageManager.PERMISSION_GRANTED
                || ActivityCompat.checkSelfPermission(this, Manifest.permission.ACCESS_FINE_LOCATION) != PackageManager.PERMISSION_GRANTED) {
            initLocationPermission();
            Toast.makeText(mActivity, "无法获取位置信息", Toast.LENGTH_SHORT);
        } else  {
            locationManager = (LocationManager) getSystemService(Context.LOCATION_SERVICE);
            if (locationManager.getLastKnownLocation(LocationManager.GPS_PROVIDER) != null || locationManager.getLastKnownLocation(LocationManager.NETWORK_PROVIDER) != null) {
                getLocation(false);
            }
        }
    }

获取位置

    private void getLocation(boolean iLM) {
        if (iLM) {
            locationManager = (LocationManager) getSystemService(Context.LOCATION_SERVICE);
        }
        String provider = "";
        Location location = locationManager.getLastKnownLocation(LocationManager.GPS_PROVIDER);
        if (location != null) {
            latitude = location.getLatitude();
            longitude = location.getLongitude();
            provider = LocationManager.GPS_PROVIDER;
        } else {
            location = locationManager.getLastKnownLocation(LocationManager.NETWORK_PROVIDER);
            if (location != null) {
                latitude = location.getLatitude();
                longitude = location.getLongitude();
                provider = LocationManager.NETWORK_PROVIDER;
            }
        }
        DecimalFormat df = new DecimalFormat("#.000000");
        String lati_str = df.format(latitude);
        String long_str = df.format(longitude);
        LUtil.i("imei : " + mImei + ", lat : " + lati_str + ", lon :" + long_str);
        locationManager.requestLocationUpdates(provider, 2000, 0, locationListener);
    }

2. 获取设备信息

    private void initDeviceID() {
        if (ActivityCompat.checkSelfPermission(this, Manifest.permission.READ_PHONE_STATE) != PackageManager.PERMISSION_GRANTED) {
            initImeiPromession();
            Toast.makeText(mActivity, "无法获取设备信息", Toast.LENGTH_SHORT);
        }else {
            TelephonyManager telephonyManager = (TelephonyManager) mContext.getSystemService(mContext.TELEPHONY_SERVICE);
            String imei = telephonyManager.getDeviceId();
            mImei = imei;
            LUtil.i("imei : " + mImei);
        }
    }
