也将其添加到您的manifest.xml

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

您需要在运行时中进行请求，如下所示。在执行任何与呼叫权限相关的任务之前，应先执行此代码。

if (ContextCompat.checkSelfPermission(thisActivity,Manifest.permission.READ_CALL_LOG)!= PackageManager.PERMISSION_GRANTED) {
    // Permission is not granted
     if (ActivityCompat.shouldShowRequestPermissionRationale(thisActivity,
            Manifest.permission.READ_CALL_LOG)) {

    } else {
        // No explanation needed; request the permission
        ActivityCompat.requestPermissions(thisActivity,
                new String[]{Manifest.permission.READ_CALL_LOG},
                MY_PERMISSIONS_READ_CALL_LOG);
    }
}

这用于读取呼叫日志权限，如果需要，也用于写入呼叫日志权限。
