更改颜色:xml中使用textColorLink属性
删除下划线:自定义一个继承UnderlineSpan 的子类,重写updateDrawState方法在其中处理
xml界面代码:
<androidx.constraintlayout.widget.ConstraintLayout xmlns:android="http://schemas.android.com/apk/res/android"
xmlns:app="http://schemas.android.com/apk/res-auto"
xmlns:tools="http://schemas.android.com/tools"
android:layout_width="match_parent"
android:layout_height="match_parent"
tools:context=".MainActivity">
<TextView
android:id="@+id/txt_link"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:text="https://www.baidu.com/"
android:autoLink="web"
android:textColorLink="@color/colorRed"
android:textIsSelectable="true"
app:layout_constraintBottom_toBottomOf="parent"
app:layout_constraintLeft_toLeftOf="parent"
app:layout_constraintRight_toRightOf="parent"
app:layout_constraintTop_toTopOf="parent" />
</androidx.constraintlayout.widget.ConstraintLayout>
Activity界面代码:
public class MainActivity extends AppCompatActivity {
TextView txt_link ;
@Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);
txt_link = findViewById(R.id.txt_link);
NoUnderlineSpan mNoUnderlineSpan = new NoUnderlineSpan();
if (txt_link.getText() instanceof Spannable) {
Spannable s = (Spannable) txt_link.getText();
s.setSpan(mNoUnderlineSpan, 0, s.length(), Spanned.SPAN_MARK_MARK);
}
}
public class NoUnderlineSpan extends UnderlineSpan {
@Override
public void updateDrawState(TextPaint ds) {
ds.setColor(ds.linkColor);
ds.setUnderlineText(false);
}
}
}
