Android动态权限获取

1、检查权限

private boolean checkPremission(String[] needPermission) {
        if (needPermission==null||needPermission.length==0){
            return false;
        }
        boolean allGranted = true;
        for (String permission : needPermission) {
            allGranted &= ContextCompat.checkSelfPermission(this,permission)== PackageManager.PERMISSION_GRANTED;
        }
        return allGranted;
    }

2、获取权限

 if ( !checkPremission(NEED_PERMISSION)){
                    ActivityCompat.requestPermissions(MainActivity.this,NEED_PERMISSION,ACTION_REQUEST_PERMISSIONS);
                }

3、权限返回结果

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