我正在代码中动态创建一个TextView，那么如何通过代码将其宽度设置为wrap_content呢?

I am dynamically creating a TextView in code ,so is there anyway to how to set its width to wrap_content through code?

推荐答案

TextView pf = new TextView(context);
pf.setLayoutParams(new LayoutParams(LayoutParams.WRAP_CONTENT, LayoutParams.WRAP_CONTENT));

对于ConstraintLayout等其他布局，它们具有自己的LayoutParams，例如:

For different layouts like ConstraintLayout and others, they have their own LayoutParams, like so:

pf.setLayoutParams(new ConstraintLayout.LayoutParams(ViewGroup.LayoutParams.WRAP_CONTENT, ViewGroup.LayoutParams.WRAP_CONTENT)); 

或

parentView.addView(pf, new LayoutParams(LayoutParams.WRAP_CONTENT, LayoutParams.WRAP_CONTENT));
