我已经创建了一个程序,可以访问您的位置,为此,我需要获得允许访问我的位置的权限。我知道要申请的权限以及如何处理该权限,但我无法在我的主程序中完成。每次我尝试添加权限时,它都不会读取requestPermission(),为了使其读取,我也添加了@RequiresApi(api=Build.VERSION\u CODES.M)这个。有人能告诉我如何在我的代码中添加它吗。

我有两个类:1)netwrokprovider活动,我在其中调用我的2)类ApplocationService。我在这里分享我的代码。请帮我解决这个问题

我需要的许可

if (ActivityCompat.checkSelfPermission(this,Manifest.permission.ACCESS_FINE_LOCATION) != PackageManager.PERMISSION_GRANTED && ActivityCompat.checkSelfPermission(this,Manifest.permission.ACCESS_COARSE_LOCATION) != PackageManager.PERMISSION_GRANTED) {

        requestPermissions(new String[]{Manifest.permission.ACCESS_FINE_LOCATION,Manifest.permission.ACCESS_COARSE_LOCATION,
                Manifest.permission.INTERNET
        },10);
        return;

    }
 @Override
public void onRequestPermissionsResult(int requestCode, @NonNull String[] permissions, @NonNull int[] grantResults) {

    switch (requestCode)
    {
        case 10:
                if(grantResults.length>0 && grantResults[0] == PackageManager.PERMISSION_GRANTED)
                {
                    configureButton();
                    return;
                }
    }
}
我需要在其中添加此权限的ApplocationClass

您需要添加清单上的权限,要支持等于或高于23的API,您还必须通过编程进行请求。

您需要在maniufest中添加此权限

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


最好使用
FusedLocationProviderAPI
。它只提供纬度和经度。那么你需要什么?我需要完整地址。@Piyus谢谢你的建议。我已经尝试了FusedLocationProviderAPI。但是,我想要的完整地址是街道号,本地地址。我也添加了。我已经在mainfest中添加了。你能告诉我在我的代码(类:ApplocationService)中在哪里添加权限吗。因为我无法读取我的requestpermission()权限方法。如果(isReadStorageAllowed()){添加你的谷歌地图活动}其他{requestStoragePermission();}私有布尔值isReadStorageAllowed(){//获取权限状态int result=Cont
