- 权限申请监听设置
this.setListener(new PermissionListener() { // 申请到所需全部权限 @Override public void onGranted(int permissionRequestCode) { if (mPermissionRequestCode == permissionRequestCode){ UIUtil.toast("已获取到相关权限！进行后续操作！"); } } // 未申请到所需全部权限 @Override public void onDenied(List deniedPermission, int permissionRequestCode) { if (mPermissionRequestCode == permissionRequestCode){ UIUtil.toast("未获取到相关权限！不能进行后续操作！"); } } // 未申请到所需全部权限，并存在部分权限勾选了不再提示选项。 @Override public void onShouldShowRationale(List deniedPermission, int permissionRequestCode) { if (mPermissionRequestCode == permissionRequestCode){ // 跳转到应用详情，进行权限设置 startActivity(getAppDetailSettingIntent()); } } }); - 申请权限
// 没有权限，去申请 requestPermissions(mPermissionRequestCode,perms);更多相关文章
