文字超链接—布局实现和代码实现

1：布局实现
//主类中的实现代码

import android.app.Activity;
import android.os.Bundle;
import android.text.SpannableString;
import android.text.method.LinkMovementMethod;
import android.widget.TextView;

public class MainActivity extends Activity {
    private TextView text;
    @Override
    protected void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.activity_main);
        text=(TextView) findViewById(R.id.chaolianjie);
        text.setMovementMethod(LinkMovementMethod.getInstance());
    }
}

//布局中实现代码

<RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android" xmlns:tools="http://schemas.android.com/tools" android:layout_width="match_parent" android:layout_height="match_parent" tools:context="com.example.test.MainActivity" >

    <TextView  android:id="@+id/chaolianjie" android:layout_width="wrap_content" android:layout_height="wrap_content" android:layout_alignParentLeft="true" android:layout_alignParentTop="true" android:layout_marginTop="20dp" android:text="@string/chaolianjie android:textAppearance="?android:attr/textAppearanceMedium" android:textSize="22sp" android:textColor="#ccc" /> 
</RelativeLayout>

自定义一个@String 在xml中调用

2：代码实现
//主类中的实现代码

import android.app.Activity;
import android.os.Bundle;
import android.text.SpannableString;
import android.text.Spanned;
import android.text.method.LinkMovementMethod;
import android.text.style.URLSpan;
import android.widget.TextView;

public class MainActivity extends Activity {
    private TextView text;
    private SpannableString  ssp=null;
    @Override
    protected void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.activity_main);
        //使用代码实现超链接
        text=(TextView) findViewById(R.id.text);
        ssp=new SpannableString("字体测试字体大小一半两倍前景色背景色正常粗体斜体粗斜体下划线删除线x1x2电话邮件网站短信彩信地图X轴综合/bot");
        ssp.setSpan(new URLSpan("http://www.baidu.com"),0, 10, Spanned.SPAN_EXCLUSIVE_EXCLUSIVE);
        text.setText(ssp);
        text.setMovementMethod(LinkMovementMethod.getInstance());
    }
}

//布局中的实现代码

<RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android" xmlns:tools="http://schemas.android.com/tools" android:layout_width="match_parent" android:layout_height="match_parent" tools:context="com.example.test.MainActivity" >

        <TextView android:id="@+id/text" android:layout_width="wrap_content" android:layout_height="wrap_content" />
</RelativeLayout>
