How can I call a number from button press in Android?
提问by Nucleotide
I'm very much a beginner at this and I'm struggling to get this to work.
我是这方面的初学者，我正在努力让它发挥作用。
When button is pressed, I simply want the dialer to open with the specified number automatically inputted.
当按下按钮时，我只想打开拨号器并自动输入指定的号码。
So far I've tried the following:
到目前为止，我已经尝试了以下方法：
Button btn_call_us = (Button) findViewById(R.id.btn_call_us);
btn_call_us.setOnClickListener(new View.OnClickListener() {
public void onClick(View v) {
Intent callIntent = new Intent(Intent.ACTION_CALL);
callIntent.setData(Uri.parse("tel:00000000"));
startActivity(callIntent);
}
});
I've also tried:
我也试过：
Button btn_call_us = (Button) findViewById(R.id.btn_call_us);
btn_call_us.setOnClickListener(new View.OnClickListener() {
public void onClick(View v) {
String phoneno="00000000";
Intent i=new Intent(Intent.ACTION_CALL,Uri.parse(phoneno));
startActivity(i);
}
});
I've added the permission ACTION_CALL to the manifest.
我已将权限 ACTION_CALL 添加到清单中。
Whenever I click the Call button the app force closes.
每当我单击呼叫按钮时，应用程序强制关闭。
Any assistance would be greatly appreciated.
任何帮助将不胜感激。
Thank you!
谢谢！

String number = "12345678";
Intent intent = new Intent(Intent.ACTION_CALL);
intent.setData(Uri.parse("tel:" +number));
startActivity(intent);
You need to add this Permission to your manifest.
您需要将此权限添加到您的清单中。
<uses-permission android:name="android.permission.CALL_PHONE"></uses-permission>

i think you Must add <uses-permission android:name="android.permission.CALL_PHONE" />in Manifest.
我认为您必须<uses-permission android:name="android.permission.CALL_PHONE" />在 Manifest 中添加。

If you want the dialer to open with the number use ACTION_DIAL
如果您希望拨号器使用该号码打开，请使用 ACTION_DIAL
Intent i=new Intent(Intent.ACTION_DIAL,Uri.parse("tel:" + phoneno));
You do not need any permission
您不需要任何许可

Add the following in the manifest file and it should work fine -
在清单文件中添加以下内容，它应该可以正常工作 -
<uses-permission android:name="android.permission.CALL_PHONE"/>

Try this.
试试这个。
startActivity(new Intent(Intent.ACTION_CALL, Uri.parse("tel:" + phoneno)));
Also, add the permission android.permission.CALL_PHONEin your manifestfile.
此外，android.permission.CALL_PHONE在您的manifest文件中添加权限。

In your Android Phone Go to: "Setting"-> "InstalledApp"-> "find your app"-> "App Permission"-> "Here allow the "Telephone Permission" Hope it will help you
在您的 Android 手机中转到：“设置”->“已安装的应用程序”->“查找您的应用程序”->“应用程序权限”->“此处允许“电话权限”希望对您有所帮助
