我正在使用以下代码在Android中拨打电话,但它给了我安全例外,请帮助。

 posted_by = "111-333-222-4";

 String uri = "tel:" + posted_by.trim() ;
 Intent intent = new Intent(Intent.ACTION_CALL);
 intent.setData(Uri.parse(uri));
 startActivity(intent);

权限

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

异常

// Java
String mobileNumber = "99XXXXXXXX";
Intent intent = new Intent();
intent.setAction(Intent.ACTION_DIAL); // Action for what intent called for
intent.setData(Uri.parse("tel: " + mobileNumber)); // Data with intent respective action on intent
startActivity(intent);

// Kotlin
val mobileNumber = "99XXXXXXXX"
val intent = Intent()
intent.action = Intent.ACTION_DIAL // Action for what intent called for
intent.data = Uri.parse("tel: $mobileNumber") // Data with intent respective action on intent
startActivity(intent)

其他回答

你也可以用这个:

String uri = "tel:" + posted_by.replaceAll("[^0-9|\\+]", "");

为了避免这种情况,可以使用GUI来输入权限。Eclipse会考虑在哪里插入权限标记,通常情况下不这样做是正确的

在Android中,对于某些功能,您需要将权限添加到Manifest文件。

转到项目AndroidManifest.xml 单击Permissions选项卡 点击添加 选择使用权限 请看下面的快照

6.保存清单文件,然后运行项目。 您的项目现在应该按预期运行。

^答案在于异常输出“需要android.permission”。CALL_PHONE”:)

// Java
String mobileNumber = "99XXXXXXXX";
Intent intent = new Intent();
intent.setAction(Intent.ACTION_DIAL); // Action for what intent called for
intent.setData(Uri.parse("tel: " + mobileNumber)); // Data with intent respective action on intent
startActivity(intent);

// Kotlin
val mobileNumber = "99XXXXXXXX"
val intent = Intent()
intent.action = Intent.ACTION_DIAL // Action for what intent called for
intent.data = Uri.parse("tel: $mobileNumber") // Data with intent respective action on intent
startActivity(intent)
