Programmatically set gravity to vertically center content of HorizontalScrollView
提问by Dynde
I have a HorizontalScrollView containing a LinearLayout. I can't seem to get the content to vertically center inside my scrollview, I can't set gravity on the horizontalscrollview, even though I tried with a LinearLayout.LayoutParams when setting the scrollview as contentview.
我有一个包含 LinearLayout 的 HorizontalScrollView。我似乎无法让内容在我的滚动视图中垂直居中，我无法在水平滚动视图上设置重力，即使我在将滚动视图设置为内容视图时尝试使用 LinearLayout.LayoutParams。
Can anyone help?
任何人都可以帮忙吗？
This is what I have:
这就是我所拥有的：
HorizontalScrollView sv = new HorizontalScrollView(c);
HorizontalScrollView sv = new HorizontalScrollView(c);
LinearLayout llh = new LinearLayout(c);llh.setOrientation(LinearLayout.HORIZONTAL);
LinearLayout llh = new LinearLayout(c);llh.setOrientation(LinearLayout.HORIZONTAL);
sv.addView(llh, llh_lp)
sv.addView(llh, llh_lp)
llh_lp is just simple wrap_content params.
llh_lp 只是简单的 wrap_content 参数。
setContentView(sv)
setContentView(sv)
And I tried adding linearlayout.layoutparams with gravity = gravity.center_vertical too, on the setContentView call.
我也尝试在 setContentView 调用中添加带有重力 = 重力.center_vertical 的 linearlayout.layoutparams。

Try this way..
试试这个方法。。
HorizontalScrollView sv = new HorizontalScrollView(this);
sv.setLayoutParams(new LayoutParams(LayoutParams.FILL_PARENT, LayoutParams.FILL_PARENT));
LinearLayout llh = new LinearLayout(this);
llh.setOrientation(LinearLayout.HORIZONTAL);
llh.setLayoutParams(new LayoutParams(LayoutParams.FILL_PARENT, LayoutParams.FILL_PARENT));
llh.setGravity(Gravity.CENTER_VERTICAL);
TextView tv = new TextView(this);
tv.setText("Policia Centeras");
tv.setBackgroundColor(-16776961);
llh.addView(tv);
sv.addView(llh);
setContentView(sv);
I hope it helps you.
我希望它能帮助你。
