以编程方式在底部定位元素

Question

RelativeLayout.LayoutParams lp = new RelativeLayout.LayoutParams(LinearLayout.LayoutParams.MATCH_PARENT,LinearLayout.LayoutParams.MATCH_PARENT);

lp.addRule(RelativeLayout.ALIGN_PARENT_BOTTOM);

layout.addView(this.adView,lp);

我正在尝试将adView放在屏幕底部。以上似乎只是它的中心。

我想知道我哪里出错了？

Answer 1

您将视图定位在底部，但填充整个屏幕，如FD_所述。因此内容以其视图为中心。

Answer 2

尝试更改：

RelativeLayout.LayoutParams lp = new RelativeLayout.LayoutParams(LinearLayout.LayoutParams.MATCH_PARENT,LinearLayout.LayoutParams.MATCH_PARENT);

为：

RelativeLayout.LayoutParams lp = new RelativeLayout.LayoutParams(RelativeLayout.LayoutParams.WRAP_CONTENT,RelativeLayout.LayoutParams.WRAP_CONTENT);

请注意，我还将LinearLayout更改为RelativeLayout
