封装了一个dialogfragment工具

dialogfragment 代替dilog的好处就不说了

/**
 * 基础DialogFragment
 * 主要是封装了一些基础的参数
 * 也可以根据自己的项目添加公有参数
 */

    }

    @Nullable
    @Override
    public View onCreateView(@NonNull LayoutInflater inflater, @Nullable ViewGroup container, @Nullable Bundle savedInstanceState) {
        //无标题
        getDialog().requestWindowFeature(Window.FEATURE_NO_TITLE);
        //设置背景透明
        getDialog().getWindow().setBackgroundDrawable(new ColorDrawable(Color.TRANSPARENT));

        normalDialog.addClickListener(mSetDialogListener);

    BaseDialogListener mSetDialogListener = new BaseDialogListener() {
        @Override
        public void onDialogStart(BaseDialog dialog, View view) {
            final NormalDialog mDialog = (NormalDialog) dialog;
            mDialog.mTitleTv.setText("text123");
            mDialog.mContentTv.setText("我是内容");
            mDialog.mOkBtn.setOnClickListener(new View.OnClickListener() {
                @Override
                public void onClick(View v) {
                    mDialog.mContentTv.setText("我是内容 text123");
                }
            });
        }
    };
}

最后除去 normalDialog还可以自定义其他dialog 比如waitDiaglog 只要集成baseDialog就可以了
