Android Realizes Horizontal Line Below Text

In this paper, we share the specific code of adding horizontal lines below Android for your reference. The specific contents are as follows

public class WhiteTextviewWithWhiteBottomLine extends LinearLayout {
 
 private Context mContext;
 
 public WhiteTextviewWithWhiteBottomLine(Context context) {
  this(context, null);
 }
 
 public WhiteTextviewWithWhiteBottomLine(Context context, @Nullable AttributeSet attrs) {
  this(context, attrs, 0);
 }
 
 public WhiteTextviewWithWhiteBottomLine(Context context, @Nullable AttributeSet attrs, int defStyleAttr) {
  super(context, attrs, defStyleAttr);
  mContext = context;
  initViews();
 }
 
 private TextView textView;
 private View viewLine;
 
 private void initViews() {
  View view = View.inflate(mContext, R.layout.view_textview_with_bottom_line, null);
 
  textView = view.findViewById(R.id.tv_view_textview_with_line);
  viewLine = view.findViewById(R.id.view_view_textview_with_line);
 
  this.addView(view);
 
  setSelected(false);
 }
 
 public void setTextViewText(String s) {
  textView.setText(s);
 }
 
 public void setLineColor(@ColorInt int color) {
  viewLine.setBackgroundColor(color);
 }
 
 public void setSelected(boolean isSelected) {
 
  if (isSelected) {
   viewLine.setVisibility(VISIBLE);
  } else {
   viewLine.setVisibility(GONE);
  }
 }
 
 public boolean isSelected() {
  if (viewLine.getVisibility() == View.VISIBLE) {
   return true;
  }else {
   return false;
  }
 }
}

Layout file:

<?xml version="1.0" encoding="utf-8"?>
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
 android:layout_width="match_parent"
 android:layout_height="match_parent"
 android:orientation="vertical">
 
 <LinearLayout
  android:layout_width="wrap_content"
  android:layout_height="wrap_content"
  android:gravity="center"
  android:orientation="vertical">
 
  <TextView
   android:id="@+id/tv_view_textview_with_line"
   android:layout_width="wrap_content"
   android:layout_height="wrap_content"
   android:gravity="center"
   android:padding="10dp"
   android:text=" Test "
   android:textColor="@color/white"
   android:textSize="12sp" />
 
  <View
   android:id="@+id/view_view_textview_with_line"
   android:layout_width="30dp"
   android:layout_height="1dp"
   android:layout_gravity="center_horizontal"
   android:background="@color/white" />
 
 </LinearLayout>
 
</LinearLayout>

If you want to change the color of text and lines, modify the contents of the layout file directly.
