        public void onClick(View v) {
            String uri = "sms to" + edit.getText().toString();
            Intent i = new Intent(android.content.Intent.ACTION_SENDTO, Uri.parse(uri));

请帮助我解决这个错误我无法解决它，因为我是安卓系统的新手我不明白这里面的确切错误。期待您最谨慎的回复提前感谢！：）

Answer 1

问题已排序在main activity.java中，我使用了这个：

 String uri = "sms to:" + edit.getText().toString();

而在清单中我声明它是

<data android:scheme="smsto" />

所以模式发生了变化

无论如何，感谢大家：）

可能是因为您没有获得互联网权限，请尝试添加以下权限。

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