android studio calling button
提问by Drew Bennett
I am trying to make an on click button which makes phone calls when pressed. Here is my code for java:
我正在尝试制作一个点击按钮，该按钮在按下时拨打电话。这是我的Java代码：
public void CampusSafClick(View view){
Intent callIntent =new Intent(Intent.ACTION_CALL);
callIntent.setData(Uri.parse("tel:6038994210"));
startActivity(callIntent);
}
I understand how to make onclick buttons, so that is not the issue.
我了解如何制作 onclick 按钮，所以这不是问题。
I have this code in the manifest:
我在清单中有这个代码：
<uses-permission android:name="android.permision.CALL_PHONE"></uses-permission>

final AlertDialog.Builder alertDialog = new AlertDialog.Builder(mContext);
alertDialog.setTitle("NKA SERVICE");
alertDialog.setMessage("Do you want to Call ?");
alertDialog.setIcon(R.drawable.call_icon);

You need Action_Dial,
你需要Action_Dial，
use below code it will open Dealer with number specified.
使用下面的代码，它将打开指定编号的经销商。
Intent intent = new Intent(Intent.ACTION_DIAL);
intent.setData(Uri.parse("tel:0123456789"));
startActivity(intent);
The tel:prefix is required, otherwhise the following exception will be thrown: java.lang.IllegalStateException: Could not execute method of the activity.
该tel:前缀是必需的，otherwhise以下将引发异常：java.lang.IllegalStateException: Could not execute method of the activity.
Action_Dialdoesn't require any permission.
Action_Dial不需要任何许可。
If you want to initiate the call directly without user's interaction, you can use action Intent.ACTION_CALL. In this case, you must add the following permission in your AndroidManifest.xml:
如果您想在没有用户交互的情况下直接发起呼叫，您可以使用 action Intent.ACTION_CALL。在这种情况下，您必须在您的 中添加以下权限AndroidManifest.xml：
<uses-permission android:name="android.permission.CALL_PHONE" />

For make a call using android, It can be implement using Intents.
对于使用android拨打电话，可以使用Intents来实现。
public void MakePhoneCall(View view){
Intent callIntent =new Intent(Intent.ACTION_CALL);
callIntent.setData(Uri.parse("tel:9961907453"));
if (ActivityCompat.checkSelfPermission(MainActivity.this,
Manifest.permission.CALL_PHONE) != PackageManager.PERMISSION_GRANTED) {
return;
}
startActivity(callIntent);
}
I have this code in the manifest:
我在清单中有这个代码：
<uses-permission android:name="android.permision.CALL_PHONE"></uses-permission>
If you are using SDK version greater than Lolipop then you should include request permission.
如果您使用的 SDK 版本高于 Lolipop，那么您应该包括请求权限。
