我在一个活动中有一些数字,我希望能够使其可选,比如超链接。当按下该号码时,它应该拨打该号码。我已经检查了Android API,但没有成功。

有人有什么想法吗?

下面注释中按钮的代码为:

DialButton=(Button)findViewById( R.id.dialbutton );

DialButton.setOnClickListener(new View.OnClickListener()
        {
            public void onClick(View view)
            {
                if(number!=null){
                      try {
                        startActivity(new Intent(Intent.ACTION_CALL, Uri.parse("tel:" + number.getText())));
                      } catch (Exception e) {
                        e.printStackTrace();
                        }
                    }//if
                  }
        });

So what gives? Also in the "AndroidManifest.xml" file I specified the permissions like this:

  <uses-permission android:name="android.permission.CALL_PRIVILEGED" />

<application android:icon="@drawable/icon" android:label="@string/app_name">
    <activity android:name=".main"
              android:label="@string/app_name">
        <intent-filter>
            <action android:name="android.intent.action.MAIN" />
            <category android:name="android.intent.category.LAUNCHER" />
        </intent-filter>
    </activity>

</application>

这错了吗?许可证放错地方了吗?

问题回答
<TextView 
   android:text="+1........"
   android:autoLink="phone" />

另外,不要忘记向清单文件添加相应的权限

<uses-permission android:name="android.permission.CALL_PHONE" />
