android 获取位置权限

Android获取位置权限需要以下步骤：

1.在AndroidManifest.xml文件中添加权限：

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

2.在Activity中请求权限：

if (ContextCompat.checkSelfPermission(this, Manifest.permission.ACCESS_FINE_LOCATION)
        != PackageManager.PERMISSION_GRANTED) {
    // Permission is not granted
    if (ActivityCompat.shouldShowRequestPermissionRationale(this,
            Manifest.permission.ACCESS_FINE_LOCATION)) {
        // Show an explanation to the user *asynchronously* -- don't block
        // this thread waiting for the user's response! After the user
        // sees the explanation, try again to request the permission.
    } else {
        // No explanation needed; request the permission
        ActivityCompat.requestPermissions(this,
                new String[]{Manifest.permission.ACCESS_FINE_LOCATION},
                MY_PERMISSIONS_REQUEST_LOCATION);
    }
} else {
    // Permission has already been granted
}

3.在回调函数onRequestPermissionsResult()中处理权限请求结果：

@Override
public void onRequestPermissionsResult(int requestCode,
        @NonNull String[] permissions,
        @NonNull int[] grantResults) {
    if (requestCode == MY_PERMISSIONS_REQUEST_LOCATION) {
        // If request is cancelled, the result arrays are empty.
        if (grantResults.length > 0
                && grantResults[0] == PackageManager.PERMISSION_GRANTED) {
            // permission was granted, yay! Do the
            // location-related task you need to do.
        } else {
            // permission denied, boo! Disable the
            // functionality that depends on this permission.
        }
        return;
    }
    // other 'case' lines to check for other
    // permissions this app might request
}

以上就是Android获取位置权限的方法。
