自定義dialog 加底部彈出動畫 加回調

step1

public class ChoosePicDialog implements View.OnClickListener {
    Activity mActivity;
    /**
     * 下面都是彈出框選擇圖片的內容
     *
     */
    private Button btnPictureStorage;
    private Button btnTakePhoto;
    private Button btnCancel;
    private OnChoseListener mOnChoseListener;

    public interface OnChoseListener {
        void onTakePhoto(); //去拍照
        void onPicAlbum(); //去開啓圖庫
    }

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

    private Dialog mDialog;  //更換頭像彈出框

    /*彈出框，選擇頭像*/
    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);
        /**設置點擊事件*/
        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();
        // 設置顯示動畫
        window.setWindowAnimations(R.style.main_menu_animstyle);
        WindowManager.LayoutParams wl = window.getAttributes();
        wl.x = 0;
        wl.y = mActivity.getWindowManager().getDefaultDisplay().getHeight();
        // 以下這兩句是爲了保證按鈕可以水平滿屏
        wl.width = ViewGroup.LayoutParams.MATCH_PARENT;
        wl.height = ViewGroup.LayoutParams.WRAP_CONTENT;

        // 設置顯示位置
        mDialog.onWindowAttributesChanged(wl);
        // 設置點擊外圍解散
        mDialog.setCanceledOnTouchOutside(true);
        mDialog.show();
    }
    /**
     * dialog點擊事件，開啓 相機，圖庫，取消
     */

    @Override
    public void onClick(View view) {
        switch (view.getId()) {
            case R.id.btn_picture_storage://圖庫
                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;
        }
    }
}

            @Override
            public void onTakePhoto() { //去拍照

            }
