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

字符串电话= "9553290143";

意图意图=新的意图(意图。ACTION_DIAL, Uri.fromParts("tel"， phone, null));

startActivity(意图);

这个演示对你有帮助…

在呼叫按钮上单击:

Intent intent = new Intent(Intent.ACTION_CALL, Uri.parse("tel:" + "Your Phone_number"));
startActivity(intent);

舱单许可:

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

你应该把它写在你的清单文件，但同时你应该在运行时问。像这样的代码:

if (ContextCompat.checkSelfPermission(this,android.Manifest.permission.CALL_PHONE) != PackageManager.PERMISSION_GRANTED) {
            ActivityCompat.requestPermissions(this, arrayOf(android.Manifest.permission.CALL_PHONE),
                REQUEST_CODE)

        } else {

// else block means user has already accepted.And make your phone call here.

}

如果你想，你可以覆盖onRequestPermissionsResult给用户更好的体验，如果你写相同的代码与else块在这里，你的用户将不需要再次点击你的按钮，在你给予权限后，它将直接调用。

你也可以用这个:

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

 if(ContextCompat.checkSelfPermission(
        mContext,android.Manifest.permission.CALL_PHONE) != 
              PackageManager.PERMISSION_GRANTED) {
                    ActivityCompat.requestPermissions((Activity) mContext, new 
                  String[]{android.Manifest.permission.CALL_PHONE}, 0);
                } else {
                    startActivity(new Intent(Intent.ACTION_CALL, Uri.parse("tel:" + "Your Number")));
                }

// 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)

你可以使用Intent。ACTION_DIAL代替Intent.ACTION_CALL。这将显示已输入号码的拨号器，但允许用户决定是否实际拨打电话。ACTION_DIAL不需要CALL_PHONE权限。
