google官方權限申請庫EasyPermissions使用方法

1. 去github上引入最新的庫 地址

2. 重寫onRequestPermissionsResult，將請求結果轉發到EasyPermisson庫

   @Override
   public void onRequestPermissionsResult(int requestCode, @NonNull String[] permissions, @NonNull int[] grantResults) {
       super.onRequestPermissionsResult(requestCode, permissions, grantResults);
       EasyPermissions.onRequestPermissionsResult(requestCode,permissions,grantResults,this);
   

3. 定義唯一的RequestCode

    private static final int RC_LOCATION_GPS_PREM =124;
   

4. 定義要請求的權限字符串(組)

   private static final String[] LOCATION_AND_GPS ={Manifest.permission.ACCESS_FINE_LOCATION,Manifest.permission.ACCESS_COARSE_LOCATION};
   

5. 請求權限

   if (EasyPermissions.hasPermissions(this,LOCATION_AND_GPS)){              
                   // 應用已經擁有了權限     
               }else {
       			// 應用沒有擁有權限
                   EasyPermissions.requestPermissions(
                           this,
                           getResources().getString(R.string.request_loacation),//使用官方提供的彈窗(`AppSettingsDialog`)的時候會用到這個字符串,作爲用戶拒絕之後彈窗的內容
                           RC_LOCATION_GPS_PREM,
                           LOCATION_AND_GPS
                   );
   

6. 實現回調接口EasyPermissions.PermissionCallbacks，定義在用戶同意或者拒絕權限申請之後的行爲

   //回調方法
    @Override
    public void onPermissionsGranted(int requestCode, @NonNull List<String> perms) {
    }
    @Override
    public void onPermissionsDenied(int requestCode, @NonNull List<String> perms) {
    }
