1、单个权限申请

   private void requestPermission() {

           if(ContextCompat.checkSelfPermission(this, permission.RECORD_AUDIO)!=PackageManager.PERMISSION_GRANTED){
               ActivityCompat.requestPermissions(this, new String[]{Manifest.permission.RECORD_AUDIO},1);
           }

           if(ContextCompat.checkSelfPermission(this, permission.CALL_PHONE)!=PackageManager.PERMISSION_GRANTED){
               ActivityCompat.requestPermissions(this, new String[]{Manifest.permission.CALL_PHONE},2);
           }


           if (ContextCompat.checkSelfPermission(this,Manifest.permission.WRITE_EXTERNAL_STORAGE)!= PackageManager.PERMISSION_GRANTED) {
   ActivityCompat.requestPermissions(this, new String[]{Manifest.permission.WRITE_EXTERNAL_STORAGE,Manifest.permission.READ_EXTERNAL_STORAGE}, 3);
   }

           if(ContextCompat.checkSelfPermission(this, permission.READ_CALL_LOG)!=PackageManager.PERMISSION_GRANTED){
               ActivityCompat.requestPermissions(this, new String[]{Manifest.permission.READ_CALL_LOG},4);
           }
       }

   @Override
       public void onRequestPermissionsResult(int requestCode, String[] permissions, int[] grantResults) {
           switch (requestCode) {
           case 1:
               if(grantResults.length>0&&grantResults[0]==PackageManager.PERMISSION_GRANTED){
               }else{
                   Toast.makeText(this, "没有录音权限", Toast.LENGTH_SHORT).show();
               }
               break;


               case 2:
                   if(grantResults.length>0&&grantResults[0]==PackageManager.PERMISSION_GRANTED){
                   }else{
                       Toast.makeText(this, "没有拨打电话权限", Toast.LENGTH_SHORT).show();
                   }
                   break;

               case 3:
                   if(grantResults.length>0&&grantResults[0]==PackageManager.PERMISSION_GRANTED){
                   }else{
                       Toast.makeText(this, "没有读写本地文件权限", Toast.LENGTH_SHORT).show();
                   }
                   break;

               case 4:
                   if(grantResults.length>0&&grantResults[0]==PackageManager.PERMISSION_GRANTED){
                   }else{
                       AlertDialog dialog=new AlertDialog.Builder(LoginActivity.this)
                               .setTitle("友情提示")
                               .setMessage("没有权限将影响使用，请开启权限！")
                               .setPositiveButton("开启", new DialogInterface.OnClickListener() {

                                   @Override
                                   public void onClick(DialogInterface dialog, int which) {
                                       dialog.cancel();
                                       ShowAppSetDetails.showInstalledAppDetails(LoginActivity.this, "com.ruibai.order");
                                   }
                               })
                               .setCancelable(false)
                               .create();
                       dialog.show();
                       Toast.makeText(this, "没有访问通话记录权限", Toast.LENGTH_LONG).show();
                   }
                   break;
           default:
               break;
           }
           super.onRequestPermissionsResult(requestCode, permissions, grantResults);
       }

2，一次申请多条权限

private static final int MY_PERMISSIONS_RECORD_AUDIO = 1;
   private static final int MY_PERMISSIONS_WRITE_EXTERNAL_STORAGE = 2;
   private static final int MY_PERMISSIONS_CALL_PHONE = 3;
   private static final int MY_PERMISSIONS_READ_CALL_LOG = 4;

   String[] permissions = new String[]{
           Manifest.permission.RECORD_AUDIO,
           Manifest.permission.WRITE_EXTERNAL_STORAGE,
           Manifest.permission.CALL_PHONE,
           Manifest.permission.READ_CALL_LOG
   };

//声明一个集合，存储用户拒绝授权的权限
List<String>mPermissionList=new ArrayList<String>();

最好写在onStart中：

@Override
protected void onStart() {
if (Build.VERSION.SDK_INT >= Build.VERSION_CODES.M) {

           for (int i = 0; i < permissions.length; i++) {
               if (ContextCompat.checkSelfPermission(LoginActivity.this, permissions[i]) != PackageManager.PERMISSION_GRANTED) {
                   mPermissionList.add(permissions[i]);
               }
           }
           if (mPermissionList.isEmpty()) {//未授予的权限为空，表示都授予了
               Toast.makeText(LoginActivity.this,"已经授权",Toast.LENGTH_LONG).show();
           } else {//请求权限方法
               String[] permissions = mPermissionList.toArray(new String[mPermissionList.size()]);//将List转为数组
               ActivityCompat.requestPermissions(LoginActivity.this, permissions, MY_PERMISSIONS_RECORD_AUDIO);
               ActivityCompat.requestPermissions(LoginActivity.this, permissions, MY_PERMISSIONS_WRITE_EXTERNAL_STORAGE);
               ActivityCompat.requestPermissions(LoginActivity.this, permissions, MY_PERMISSIONS_CALL_PHONE);
               ActivityCompat.requestPermissions(LoginActivity.this, permissions, MY_PERMISSIONS_READ_CALL_LOG);

           }
       }
       super.onStart();
   }

                       .setMessage("没有权限将影响使用，请开启权限！")
                       .setPositiveButton("开启", new DialogInterface.OnClickListener() {

                           @Override
                           public void onClick(DialogInterface dialog, int which) {
                               dialog.cancel();
                               ShowAppSetDetails.showInstalledAppDetails(LoginActivity.this, "com.ruibai.order");
                           }
                       })
                       .setCancelable(false)
                       .create();
               dialog.show();
           }
       }

super.onRequestPermissionsResult(requestCode, permissions, grantResults);
