本文实例为大家分享了Android实现文字下方加横线的具体代码，供大家参考，具体内容如下
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;
}
}
}
布局文件：
<?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="测试" 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>
如果想改变文字、线的颜色这些，直接修改布局文件中的内容。
