EasyPermission是一个简易的权限请求库。

使用方法

在程序入口的Activity中的onCreate方法中初始化它:

    @Override
    protected void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        ....
        EasyPermission.initialize(this);
    }

初始化后可以在任意时候请求权限.

EasyPermission.checkPermissions(new PermissionListener() {
            @Override
            public void onAllGranted() {
                Log.d(TAG, "onAllGranted: ");
            }

            @Override
            public void atLeastOneDenied(List<String> deniedPermissions, List<String> grantedPermissions) {
                Log.d(TAG, "atLeastOneDenied: denied: ");
                Log.d(TAG, "atLeastOneDenied: ###########################");
                for (String denied : deniedPermissions) {
                    Log.d(TAG, "atLeastOneDenied: " + denied);
                }
                Log.d(TAG, "atLeastOneDenied: granted: ");
                Log.d(TAG, "atLeastOneDenied: ###########################");
                for (String granted : grantedPermissions) {
                    Log.d(TAG, "atLeastOneDenied: " + granted);
                }

                // Activity的onResume尚未回掉，不能直接弹出部分dialog
                // showPermissionDeniedDialog(deniedPermissions);
            }
        }, Manifest.permission.CALL_PHONE, Manifest.permission.WRITE_EXTERNAL_STORAGE);

如果有在被拒绝权限时显示自定义的DialogFragment的需求或者是希望onResume被回掉之后，权限的请求结果再被回调，可以使用以下方法:

    private EasyPermissionHelper permissionHelper;

    @Override
    protected void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        ....

        permissionHelper = new EasyPermissionHelper(this);
    }

    @Override
    protected void onResume() {
        super.onResume();
        permissionHelper.onResume();
    }

    @Override
    protected void onDestroy() {
        super.onDestroy();
        permissionHelper.onDestroy();
    }

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

    private void doRequest() {
        permissionHelper.checkPermissions(new PermissionListener() {
            @Override
            public void onAllGranted() {

            }

            @Override
            public void atLeastOneDenied(List<String> deniedPermissions, List<String> grantedPermissions) {
              // 此处回调是在onResume之后，可以直接显示DialogFragment  
              showPermissionDeniedDialog(deniedPermissions);
            }
        }, Manifest.permission.CALL_PHONE, Manifest.permission.WRITE_EXTERNAL_STORAGE);
    }

• EasyPermission.initialize 和EasyPermission.checkPermissions 方法不再适用于这种情况.
• 以上写法可以写在基类中方便调用

添加依赖到项目

1. 在项目根目录的build.gradle添加

allprojects {
       repositories {
           ...
           maven { url "https://jitpack.io" }
       }
   }

2. 添加依赖

dependencies {
       compile 'com.github.billy96322:EasyPermission:0.0.1'
   }
