Android 6.0权限封装整合

拨打电话权限

以拨打电话为例，首先在Manifest文件中定义好拨打电话权限：  <uses-permission android:name="android.permission.CALL_PHONE"/>第一步（当用户点击拨打电话按钮时执行如下代码）：MPermissionUtils.requestPermissionsResult(this, 1, new String[]{Manifest.permission.CALL_PHONE}                , new MPermissionUtils.OnPermissionListener() {                    @Override                    public void onPermissionGranted() {                        Toast.makeText(MainActivity.this, "授权成功,执行拨打电话操作!", Toast.LENGTH_SHORT).show();                    }                    @Override                    public void onPermissionDenied() {                        MPermissionUtils.showTipsDialog(MainActivity.this);                    }                });第二步（重写onRequestPermissionsResult()方法，使用MPermissionUtils类中的方法进行接管）：@Override    public void onRequestPermissionsResult(int requestCode, @NonNull String[] permissions, @NonNull int[] grantResults) {        MPermissionUtils.onRequestPermissionsResult(requestCode, permissions, grantResults);        super.onRequestPermissionsResult(requestCode, permissions, grantResults);    }

另外韩国人也封装了权限框架PermissionGen需要的点击查看使用方法不再赘述！
