LinearLayout.LayoutParam不再具有addRule函数或LinearLayout.Bottom吗? [英] LinearLayout.LayoutParam no longer have addRule function nor LinearLayout.Bottom?

问题描述

我正在动态创建一些视图并插入LinearLayout中.我计划将其从上到下按顺序插入. (默认情况下，它会插入到底部和顶部).

I'm creating some views dynamically and insert into a LinearLayout. I'm planning to insert it from the Top to Bottom orderly. (by default, it insert at Bottom and to the Top).

我在 https://stackoverflow.com/a/12290985/3286489 中找到了该指南.

I found the guide here https://stackoverflow.com/a/12290985/3286489.

LinearLayout linearLayout = (LinearLayout) findViewById(R.id.mylayout);
TextView txt1 = new TextView(MyClass.this);
LinearLayout.LayoutParams layoutParams =
            (RelativeLayout.LayoutParams) txt1.getLayoutParams();
layoutParams.addRule(LinearLayout.BOTTOM, 1);
txt1.setLayoutParams(layoutParams);
linearLayout.addView(txt1);

但是，当我尝试使用它时，显然找不到LinearLayout的addRule函数和LinearLayout.BOTTOM值.我有什么想念吗?

However, when I try it, apparently there's no more addRule function nor LinearLayout.BOTTOM value for LinearLayout found. Did I miss anything?

推荐答案

显然，没有LinearLayout.BOTTOM之类的东西，我们也无法为LinearLayout添加规则.

Apparently there is no such thing as LinearLayout.BOTTOM, nor can we add rule for LinearLayout.

但是好消息是将其插入LinearLayout中，可以确定顺序.只需使用addView函数和以下3个参数

But the good news is to insert into LinearLayout, one could decide the sequence.. Just use the addView function with 3 arguments as below

mLayout.addView(view, index, param);

index确定了顺序.
