Android 将布局高度设置为Wrapcontent以动态创建textview

我以编程方式创建了LinearLayout，如下所示

LinearLayout wrapper = new LinearLayout(this.getContext());

文本视图为

TextView et=newtextview（getContext（））

我希望TextView布局高度为wrapcontent，所以我这样做了

et.setLayoutParams(new LayoutParams(android.view.ViewGroup.LayoutParams.WRAP_CONTENT, android.view.ViewGroup.LayoutParams.WRAP_CONTENT));

然后我将Textview et添加到LinearLayout中，如下所示

wrapper.addView(et);

但当我将LayoutParams设置为上面的值时，我的textview将消失，并且不会显示在UI中。
如果我默认删除它，Textview将高度作为匹配父对象

如何将textviews layouthweight设置为
WRAP\u CONTENT
？
试试这个

LinearLayout first_lay = new LinearLayout(this);

LinearLayout.LayoutParams lp_icon = new LinearLayout.LayoutParams(LinearLayout.LayoutParams.MATCH_PARENT, LinearLayout.LayoutParams.MATCH_PARENT);

first_lay.setOrientation(LinearLayout.VERTICAL);
first_lay.setLayoutParams(lp_icon);

LinearLayout.LayoutParams tests = new LinearLayout.LayoutParams(LinearLayout.LayoutParams.WRAP_CONTENT, LinearLayout.LayoutParams.WRAP_CONTENT, Gravity.CENTER);

TextView text1 = new TextView(this);
text1.setLayoutParams(tests);
text1.setText("Text");
text1.setTextSize(18);

first_lay.addView(text1);

还必须将父线性布局添加到主contentlayout父级中，即它在侧活动视图中都可见

  LinearLayout child_insidenew_layout = new LinearLayout(getActivity());
                        child_insidenew_layout.setOrientation(LinearLayout.HORIZONTAL);
 LinearLayout.LayoutParams child_inside_paramsnew = new LinearLayout.LayoutParams(LinearLayout.LayoutParams.MATCH_PARENT, LinearLayout.LayoutParams.MATCH_PARENT);
                        child_insidenew_layout.setLayoutParams(child_inside_paramsnew);
  child_insidenew_layout.setGravity(Gravity.CENTER_VERTICAL);
                        child_insidenew_layout.setBackgroundResource(R.drawable.layout_selector);
TextView textrootname = new TextView(getActivity());
 LinearLayout.LayoutParams TextView_params = new LinearLayout.LayoutParams(LinearLayout.LayoutParams.WRAP_CONTENT, LinearLayout.LayoutParams.WRAP_CONTENT);
  textrootname.setText("here is ur text");
  textrootname.setSingleLine(true);
  textrootname.setGravity(Gravity.CENTER);
  textrootname.setTextColor(Color.BLACK);
  textrootname.setTextSize(15);
  child_insidenew_layout.addView(textrootname, TextView_params);

您是否尝试过在其中设置文本。我认为它会消失，因为它没有显示。我设置了文本，如果我没有为textview设置layoutparams，我的文本是可见的。您是否在活动中设置了任何setcontentview:）@Mario您是否使用了
setcontentview（first\u lay）
或将
first\u lay
添加到其他xml视图中
