Android(安卓)动态获取权限(6.0 , 7.0)

在Android API23以上，需要动态获取网络权限。以API版本23 6.0手机获取电话权限为例

/**     * 请求打电话的权限码     */    private static final int REQUEST_CALL_PHONE = 100;    /**         * 点击按钮申请权限         */        findViewById(R.id.callButton).setOnClickListener(new View.OnClickListener() {            @Override            public void onClick(View view) {            //点击按钮调用申请权限的方法                requestPermission();            }        });private void requestPermission() {        //判断Android版本是否大于23        if (Build.VERSION.SDK_INT >= Build.VERSION_CODES.M) {            int checkCallPhonePermission = ContextCompat.checkSelfPermission(this, Manifest.permission.CALL_PHONE);            if (checkCallPhonePermission != PackageManager.PERMISSION_GRANTED) {                ActivityCompat.requestPermissions(this, new String[]{Manifest.permission.CALL_PHONE}, REQUEST_CALL_PHONE);                return;            } else {                //已有权限            }        } else {            //API 版本在23以下        }    }

在activity中有申请权限的回调

/**     * 注册权限申请回调     * @param requestCode 申请码     * @param permissions 申请的权限     * @param grantResults 结果     */    @Override    public void onRequestPermissionsResult(int requestCode, String[] permissions, int[] grantResults)    {        switch (requestCode) {            case REQUEST_CALL_PHONE:                if (grantResults[0] == PackageManager.PERMISSION_GRANTED) {                    callPhone();                }                else {                    // Permission Denied                    Toast.makeText(MainActivity.this, "CALL_PHONE Denied", Toast.LENGTH_SHORT).show();                }                break;            default:                super.onRequestPermissionsResult(requestCode, permissions, grantResults);        }    }

这样点击按钮时的弹框样式，为手机系统弹框
