How do I get the dialer to open with phone number displayed?
提问by Nik
I don't need to call the phone number, I just need the dialer to open with the phone number already displayed. What Intentshould I use to achieve this?
我不需要拨打电话号码，我只需要拨号器打开，电话号码已经显示。我Intent应该用什么来实现这一目标？
回答by AAnkit
Two ways to achieve it.
有两种方法可以实现。
1) Need to start the dialer via code, without user interaction.
1) 需要通过代码启动拨号器，无需用户交互。
You need Action_Dial,
你需要Action_Dial，
use below code it will open Dialer with number specified
使用下面的代码，它将打开指定号码的拨号器
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.
'tel:' 前缀是必需的，否则将抛出以下异常： java.lang.IllegalStateException: 无法执行活动的方法。
Action_Dial doesn't require any permission.
Action_Dial 不需要任何权限。
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:
如果您想直接发起呼叫而无需用户交互，您可以使用 action Intent.ACTION_CALL。在这种情况下，您必须在 AndroidManifest.xml 中添加以下权限：
<uses-permission android:name="android.permission.CALL_PHONE" />
2) Need user to click on Phone_Number string and start the call.
2) 需要用户点击 Phone_Number 字符串并开始通话。
android:autoLink="phone"
You need to use TextView with below property.
您需要使用具有以下属性的 TextView。
android:autoLink="phone" android:linksClickable="true" a textView property
android:autoLink="phone" android:linksClickable="true" 一个 textView 属性
You don't need to use intent or to get permission via this way.
您不需要使用意图或通过这种方式获得许可。

Pretty late on the answer, but if you have a TextViewthat you're showing the phone number in, then you don't need to deal with intents at all, you can just use the XML attribute android:autoLink="phone"and the OS will automatically initiate an ACTION_DIALIntent.
答案很晚了，但是如果你有一个TextView你正在显示电话号码的，那么你根本不需要处理意图，你可以只使用 XML 属性android:autoLink="phone"，操作系统将自动启动一个ACTION_DIAL意图。

Okay, it is going to be extremely late answer to this question. But here is just one sample if you want to do it in Kotlin.
好的，这个问题的答案会非常晚。但如果您想在Kotlin 中进行，这里只是一个示例。
val intent = Intent(Intent.ACTION_DIAL)
intent.data = Uri.parse("tel:<number>")
startActivity(intent)
Thought it might help someone.
认为它可能会帮助某人。

As @ashishduh mentioned above, using android:autoLink="phoneis also a good solution. But this option comes with one drawback, it doesn't work with all phone number lengths. For instance, a phone number of 11 numbers won't work with this option. The solution is to prefix your phone numbers with the country code.
正如上面提到的@ashishduh，使用android:autoLink="phone也是一个很好的解决方案。但此选项有一个缺点，它不适用于所有电话号码长度。例如，包含 11 个号码的电话号码不适用于此选项。解决方案是在您的电话号码前加上国家/地区代码。
Example:
例子：
08034448845won't work
08034448845不会工作
but +2348034448845will
但+2348034448845会

<TextView
android:id="@+id/phoneNumber"
android:autoLink="phone"
android:linksClickable="true"
android:text="+91 22 2222 2222"
/>
This is how you can open EditText label assigned number on dialer directly.
这就是如何直接在拨号器上打开 EditText 标签分配的号码。

Add permission in manifest :
在清单中添加权限：
<uses-permission android:name="android.permission.CALL_PHONE" />
Make button or any widget example : btnCall
制作按钮或任何小部件示例： btnCall
btnCall.setOnClickListener(new View.OnClickListener() {
@Override
public void onClick(View v) {
Intent callIntent = new Intent(Intent.ACTION_DIAL);
callIntent.setData(Uri.parse("tel: +98990*******");
startActivity(callIntent);
}
});
