1. 创建类 PayWayDialog 继承自 Dialog

@Override
    protected void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.pay_dialog);
        Window dialogWindow = getWindow();  //得到弹框
        dialogWindow.setGravity(Gravity.BOTTOM); //设为在底部
        WindowManager.LayoutParams lp = dialogWindow.getAttributes();
        lp.width = AbsListView.LayoutParams.MATCH_PARENT;  //宽度设置
        lp.y = 0;  //离底部距离为0
        dialogWindow.setAttributes(lp);
    }

2. 自定义 dialog 布局

 

3. 调用

PayWayDialog payWayDialog = new PayWayDialog(OrderActivity.this);
            payWayDialog.show();

点击事件在类 PayWayDialog 中设置
