step1

public class ChoosePicDialog implements View.OnClickListener {
    Activity mActivity;
    /**
     * 下面都是弹出框选择图片的内容
     *
     */
    private Button btnPictureStorage;
    private Button btnTakePhoto;
    private Button btnCancel;
    private OnChoseListener mOnChoseListener;

    public interface OnChoseListener {
        void onTakePhoto(); //去拍照
        void onPicAlbum(); //去开启图库
    }

    public ChoosePicDialog(Activity activity,OnChoseListener onChoseListener) {
        this.mActivity = activity;
        this.mOnChoseListener = onChoseListener;
        showDialog();
    }

    private Dialog mDialog;  //更换头像弹出框

    /*弹出框，选择头像*/
    private void showDialog() {
        View view = View.inflate(mActivity, R.layout.photo_choose_dialog, null);
        btnPictureStorage = (Button) view.findViewById(R.id.btn_picture_storage);
        btnTakePhoto = (Button) view.findViewById(R.id.btn_take_photo);
        btnCancel = (Button) view.findViewById(R.id.btn_cancel);
        /**设置点击事件*/
        btnPictureStorage.setOnClickListener(this);
        btnTakePhoto.setOnClickListener(this);
        btnCancel.setOnClickListener(this);

        mDialog = new Dialog(mActivity, R.style.transparentFrameWindowStyle);
        mDialog.setContentView(view, new ViewGroup.LayoutParams(ViewGroup.LayoutParams.MATCH_PARENT,
                ViewGroup.LayoutParams.WRAP_CONTENT));
        Window window = mDialog.getWindow();
        // 设置显示动画
        window.setWindowAnimations(R.style.main_menu_animstyle);
        WindowManager.LayoutParams wl = window.getAttributes();
        wl.x = 0;
        wl.y = mActivity.getWindowManager().getDefaultDisplay().getHeight();
        // 以下这两句是为了保证按钮可以水平满屏
        wl.width = ViewGroup.LayoutParams.MATCH_PARENT;
        wl.height = ViewGroup.LayoutParams.WRAP_CONTENT;

        // 设置显示位置
        mDialog.onWindowAttributesChanged(wl);
        // 设置点击外围解散
        mDialog.setCanceledOnTouchOutside(true);
        mDialog.show();
    }
    /**
     * dialog点击事件，开启 相机，图库，取消
     */

    @Override
    public void onClick(View view) {
        switch (view.getId()) {
            case R.id.btn_picture_storage://图库
                mOnChoseListener.onPicAlbum();
                mDialog.dismiss();
                break;
            case R.id.btn_take_photo: //拍照
                mOnChoseListener.onTakePhoto();
                mDialog.dismiss();
                break;
            case R.id.btn_cancel://取消
                mDialog.dismiss();
                break;
        }
    }
}

        android:layout_height="wrap_content"
        android:background="@drawable/photo_gallery_selector"
        android:paddingBottom="10dip"
        android:paddingTop="10dip"
        android:id="@+id/btn_picture_storage"

</LinearLayout>

style
transparentFrameWindowStyle

    <!--选择头像动画-->
    <style name="transparentFrameWindowStyle" parent="android:style/Theme.Dialog">
        <item name="android:windowBackground">@drawable/photo_choose_bg</item>
    </style>

main_menu_animstyle

    <style name="main_menu_animstyle">
        <item name="android:windowEnterAnimation">@anim/photo_dialog_in_anim</item>
        <item name="android:windowExitAnimation">@anim/photo_dialog_out_anim</item>
    </style>

两个方向透明动画

<?xml version="1.0" encoding="utf-8"?>

    <translate
        android:duration="500"

具体使用

       new ChoosePicDialog(this, new ChoosePicDialog.OnChoseListener() {
            @Override
            public void onTakePhoto() { //去拍照

            }

            @Override
            public void onPicAlbum() {//去打开相册

            }
};
