Dialog代码,使用Builder模式构建

public class XxDialog extends Dialog {
    private Context mContext;
    private String mTitle;
    private String mContent;

    protected XxDialog(Context context) {
        super(context, R.style.marketdialog);
        this.mContext = context;
    }

    public void setmTitle(String mTitle) {
        this.mTitle = mTitle;
    }


    public void setmContent(String mContent) {
        this.mContent = mContent;
    }

    @Override
    protected void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.dialog_layout);
        getWindow().setGravity(Gravity.CENTER);   //设置dialog位置
        WindowManager.LayoutParams layoutParams = getWindow().getAttributes();
        layoutParams.width = WindowManager.LayoutParams.WRAP_CONTENT;
        layoutParams.height = WindowManager.LayoutParams.WRAP_CONTENT;
        getWindow().setAttributes(layoutParams);
        setupView();
    }
    public static class Build {
            private Context mContext;
            private String mTitle;
            private String mContent;
            public Build(final Context mContext) {
            this.mContext = mContext;
        }

        public Build setmContent(String mContent) {
            this.mContent = mContent;
            return this;
        }

        public Build setmTitle(String mTitle) {
            this.mTitle = mTitle;
            return this;
        }

        public void setImgId(@DrawableRes int imgId) {
            this.imgId = imgId;
        }

        private XxDialog create() {
            XxDialog dialog = new XxDialog(mContext);
            dialog.setmTitle(mTitle != null ? mTitle : mContext.getResources().getString(R.string.dialog_title));
            dialog.setImgId(imgId != 0 ? imgId : R.drawable.dialog_icon);
            dialog.setmContent(mContent != null ? mContent : mContext.getResources().getString(R.string.dialog_content));
            return dialog;
        }

        public XxDialog show() {
            final XxDialog dialog = create();
            dialog.show();
            return dialog;
        }
    }
}
