Android 6.0 的权限处理

检测SDKAPI如果是大于或等于23的时候，则弹出自定义的对话框提示用户是否授权，确定的话跳转到设置，应用里面去打开权限，否则退出程序。

    // 判断当前系统版本，6.0以上执行权限处理
    if (Build.VERSION.SDK_INT >= 23) {
        manageSystemPermissions();
    } else {
        initView();
    }

处理权限的请求方法：

    /* 处理系统所需权限 */
    @TargetApi(23)
    public void manageSystemPermissions() {
        final List<String> permissionsNeeded = new ArrayList<String>();
        final List<String> permissionsList = new ArrayList<String>();

        checkPermission(permissionsList, permissionsNeeded, Manifest.permission.READ_PHONE_STATE, "电话");
        checkPermission(permissionsList, permissionsNeeded, Manifest.permission.ACCESS_COARSE_LOCATION, "定位");
        checkPermission(permissionsList, permissionsNeeded, Manifest.permission.CAMERA, "相机");
        checkPermission(permissionsList, permissionsNeeded, Manifest.permission.WRITE_EXTERNAL_STORAGE, "存储");
        checkPermission(permissionsList, permissionsNeeded, Manifest.permission.RECORD_AUDIO, "录音");

        if (permissionsList.size() > 0) {
            if (permissionsNeeded.size() > 0) {
                // Need Rationale
                String message = "请允许以下权限的申请以确保应用的正常运行：" + permissionsNeeded.get(0);
                for (int i = 1; i < permissionsNeeded.size(); i++)
                    message = message + ", " + permissionsNeeded.get(i);
                    message = message + "\n" + "请点击 '设置' --> '权限' 开启相关权限 ";
                showMessageOKCancel(message, new DialogInterface.OnClickListener() {
                    @Override
                    public void onClick(DialogInterface dialog, int which) {
                        switch (which) {
                        case DialogInterface.BUTTON_POSITIVE:
                            startActivity(new Intent()
                                    .setAction(android.provider.Settings.ACTION_APPLICATION_DETAILS_SETTINGS)
                                    .setData(Uri.fromParts("package", "com.zzsoft.mobile.office.sx", null)));
                            dialog.dismiss();
                            WelcomeActivity.this.finish();
                            break;
                        case DialogInterface.BUTTON_NEGATIVE:
                            dialog.dismiss();
                            Toast.makeText(WelcomeActivity.this, "权限获取失败，正在退出……", Toast.LENGTH_LONG).show();
                            WelcomeActivity.this.finish();
                            break;
                        default:
                            break;
                        }
                    }
                });
                return;
            }
            requestPermissions(permissionsList.toArray(new String[permissionsList.size()]),
                    REQUEST_CODE_ASK_PERMISSIONS);
        } else {
            initView();
        }
    }

检测某一权限是否被授权：

    /* 检查权限是否已授权 */
    @TargetApi(23)
    private void checkPermission(List<String> permissionsList, List<String> permissionsNeeded, String permission,
            String message) {
        if (checkSelfPermission(permission) != PackageManager.PERMISSION_GRANTED) {
            permissionsList.add(permission);
            // Check for Rationale Option
            if (!shouldShowRequestPermissionRationale(permission))
                permissionsNeeded.add(message);
        }
    }

请求权限的结果回调，只有需求的权限都被授权时，才能进入程序：

    /* 请求权限结果回调 */
    @TargetApi(23)
    @Override
    public void onRequestPermissionsResult(int requestCode, String[] permissions, int[] grantResults) {
        switch (requestCode) {
        case REQUEST_CODE_ASK_PERMISSIONS:
            Map<String, Integer> perms = new HashMap<String, Integer>();
            // Initial
            perms.put(Manifest.permission.READ_PHONE_STATE, PackageManager.PERMISSION_GRANTED);
            perms.put(Manifest.permission.ACCESS_COARSE_LOCATION, PackageManager.PERMISSION_GRANTED);
            perms.put(Manifest.permission.CAMERA, PackageManager.PERMISSION_GRANTED);
            perms.put(Manifest.permission.WRITE_EXTERNAL_STORAGE, PackageManager.PERMISSION_GRANTED);
            perms.put(Manifest.permission.RECORD_AUDIO, PackageManager.PERMISSION_GRANTED);
            // Fill with results
            for (int i = 0; i < permissions.length; i++)
                perms.put(permissions[i], grantResults[i]);
            // Check for ACCESS_FINE_LOCATION
            if (perms.get(Manifest.permission.READ_PHONE_STATE) == PackageManager.PERMISSION_GRANTED
                    && perms.get(Manifest.permission.ACCESS_COARSE_LOCATION) == PackageManager.PERMISSION_GRANTED
                    && perms.get(Manifest.permission.CAMERA) == PackageManager.PERMISSION_GRANTED
                    && perms.get(Manifest.permission.WRITE_EXTERNAL_STORAGE) == PackageManager.PERMISSION_GRANTED
                    && perms.get(Manifest.permission.RECORD_AUDIO) == PackageManager.PERMISSION_GRANTED) {
                // All Permissions Granted
                initView();
            } else {
                // Permission Denied
                Toast.makeText(WelcomeActivity.this, "权限获取失败，正在退出……", Toast.LENGTH_LONG).show();
                this.finish();
            }
            break;
        default:
            super.onRequestPermissionsResult(requestCode, permissions, grantResults);
        }
    }

当第一次进行权限申请时以及在进行授权时选中了“不再提示”并拒绝授权的，弹出对话框：

    /* 第一次申请权限或点击不再询问后再次申请权限对话框 */
    private void showMessageOKCancel(String message, DialogInterface.OnClickListener okListener) {
        new AlertDialog.Builder(WelcomeActivity.this).setMessage(message).setPositiveButton("设置", okListener)
                .setNegativeButton("取消", okListener).setCancelable(false).create().show();
    }
