android:layout_alignParentBottom代码

Question

如何android:layout_alignParentBottom="true"通过代码而不是从xml 设置视频视图？

Answer 1

我假设你正在尝试添加你VideoView的RelativeLayout？

RelativeLayout relativeLayout = findViewById(R.id.your_relative_layout);
mVideo = new VideoView(this); 
RelativeLayout.LayoutParams layoutParams = new RelativeLayout.LayoutParams(LayoutParams.MATCH_PARENT, LayoutParams.MATCH_PARENT); // or wrap_content
layoutParams.addRule(RelativeLayout.ALIGN_PARENT_BOTTOM);
relativeLayout.addView(mVideo , layoutParams);

Answer 2

RelativeLayout.LayoutParams params = new RelativeLayout.LayoutParams(RelativeLayout.LayoutParams.WRAP_CONTENT, RelativeLayout.LayoutParams.WRAP_CONTENT);
params.addRule(RelativeLayout.ALIGN_PARENT_BOTTOM, RelativeLayout.TRUE);
YourVideoView.setLayoutParams(params);
