- Android Linkify示例
Android可点击链接可以通过两种不同方式创建：
1.使用布局（.xml）文件：它使用具有指定类型的autoLink属性。
<
TextView
android:id="@+id/url"
android:autoLink="web"/>2.使用Java类：它对指定类型的Linkify类使用addlLinks（）方法。
TextView webURL = new TextView(this);
webURL.setText("https://www.yoururl1.com/");
Linkify.addLinks(webURL , Linkify.WEB_URLS);
Android Linkify示例【android linkify的例子】在此示例中，我们将为Web URL，电子邮件地址和电话号码创建链接。在布局目录中创建一个activity_main.xml文件，并添加以下代码。
activity_main.xml
<
?xml version="1.0" encoding="utf-8"?>
<
RelativeLayout 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="example.srcmini.com.androidlinkify.MainActivity"><
ListView
android:id="@+id/list"
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:layout_marginBottom="50dp">
<
/ListView>
<
/RelativeLayout>创建一个自定义布局myList.xml文件，并添加以下代码。在此布局中，我们将autoLink属性与web，email和phone属性一起使用。
myList.xml
<
?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="horizontal" ><
ImageView
android:id="@+id/icon"
android:layout_width="60dp"
android:layout_height="60dp"
android:padding="5dp" /><
LinearLayout android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:orientation="vertical"><
TextView
android:id="@+id/url"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:text="Medium Text"
android:autoLink="web"
android:textStyle="bold"
android:textAppearance="?android:attr/textAppearanceMedium"
android:layout_marginLeft="10dp"
android:layout_marginTop="5dp"
android:padding="2dp"
android:textColor="#4d4d4d" />
<
TextView
android:id="@+id/email"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:text="TextView"
android:autoLink="email"
android:layout_marginLeft="10dp"/>
<
TextView
android:id="@+id/phonenumber"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:text="TextView"
android:autoLink="phone"
android:layout_marginLeft="10dp"/>
<
/LinearLayout>
<
/LinearLayout>创建一个适配器类MyListActivity.java并使用以下代码扩展ArrayAdapter < > 。
MyListActivity.java
package example.srcmini.com.androidlinkify;
import android.app.Activity;
import android.text.util.Linkify;
import android.view.LayoutInflater;
import android.view.View;
import android.view.ViewGroup;
import android.widget.ArrayAdapter;
import android.widget.ImageView;
import android.widget.TextView;
public class MyListAdapter extends ArrayAdapter<
String> {private final Activity context;
private final String[] url;
private final String[] email;
private final String[] phonenumber;
private final Integer[] imgid;
public MyListAdapter(Activity context, String[] url, String[] email, String[] phonenumber, Integer[] imgid) {
super(context, R.layout.mylist, url);
// TODO Auto-generated constructor stub
this.context=context;
this.url=url;
this.email=email;
this.phonenumber=phonenumber;
this.imgid=imgid;
}public View getView(int position, View view, ViewGroup parent) {
LayoutInflater inflater=context.getLayoutInflater();
View rowView=inflater.inflate(R.layout.mylist, null, true);
TextView titleText = (TextView) rowView.findViewById(R.id.url);
TextView subtitleText = (TextView) rowView.findViewById(R.id.email);
TextView phonenumberText = (TextView) rowView.findViewById(R.id.phonenumber);
ImageView imageView = (ImageView) rowView.findViewById(R.id.icon);
imageView.setImageResource(imgid[position]);
titleText.setText(url[position]);
subtitleText.setText(email[position]);
phonenumberText.setText(phonenumber[position]);
Linkify.addLinks(phonenumberText, Linkify.PHONE_NUMBERS);
return rowView;
};
}最后，在MainActivity.java类中，将适配器实例设置为ListView。
MianActivity.java
package example.srcmini.com.androidlinkify;
import android.support.v7.app.AppCompatActivity;
import android.os.Bundle;
import android.widget.ListView;
public class MainActivity extends AppCompatActivity {
ListView list;
String[] urls ={
"https://www.yoururl1.com/", "https://www.yoururl2.com/", "https://www.yoururl3.com/", "https://www.yoururl4.com/", "https://www.yoururl5.com/", "https://www.yoururl6.com/", "https://www.yoururl7.com/", "https://www.yoururl8.com/", "https://www.yoururl9.com/", "https://www.yoururl19.com/", };
String[] emails ={
"email_1@mail.com", "email_2@mail.com", "email_3@mail.com", "email_4@gmail.com", "email_5@mail.com", "email_6@mail.com", "email_7@mail.com", "email_8@mail.com", "email_9@gmail.com", "email_10@mail.com"
};
String[] phoneNumber ={
"+(1234)-567", "+(1234)-567", "7563654321", "9475000000", "8575000000", "+1 (919) 555-1212", "+91 (919) 555-1212", "6463654321", "5475000000", "8575000000", };
Integer[] imgid={
R.drawable.image_1, R.drawable.image_2, R.drawable.image_3, R.drawable.image_4, R.drawable.image_5, R.drawable.image_6, R.drawable.image_7, R.drawable.image_8, R.drawable.image_9, R.drawable.image_10, };
@Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);
MyListAdapter adapter=new MyListAdapter(this, urls, emails, phoneNumber, imgid);
list= findViewById(R.id.list);
list.setAdapter(adapter);
}
