如何在Android中使用意图打电话?

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

你也可以用这个:

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

更优雅的选择:

String phone = "+34666777888";
Intent intent = new Intent(Intent.ACTION_DIAL, Uri.fromParts("tel", phone, null));
startActivity(intent);

你也可以用这个:

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

只是一个简单的联机程序，不需要任何额外的权限:

private void dialContactPhone(final String phoneNumber) {
    startActivity(new Intent(Intent.ACTION_DIAL, Uri.fromParts("tel", phoneNumber, null)));
}

对于使用intent进行调用活动，您应该请求适当的权限。

为此，在AndroidManifest.xml文件中包含使用权限。

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

然后在您的活动中包含以下代码

if (ActivityCompat.checkSelfPermission(mActivity,
        Manifest.permission.CALL_PHONE) == PackageManager.PERMISSION_GRANTED) {
    //Creating intents for making a call
    Intent callIntent = new Intent(Intent.ACTION_CALL);
    callIntent.setData(Uri.parse("tel:123456789"));
    mActivity.startActivity(callIntent);

}else{
    Toast.makeText(mActivity, "You don't assign permission.", Toast.LENGTH_SHORT).show();
}

11-25 14:47:01.681: ERROR/AndroidRuntime(302): blah blah...requires android.permission.CALL_PHONE

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