我遇到以下崩溃

谁能帮忙吗？

Answer 1

这是一个示例代码，您可以使用它来请求运行时权限:

private static final int MY_PERMISSIONS_REQUEST_READ_FINE_LOCATION = 100;

和

// Here, thisActivity is the current activity
if (ContextCompat.checkSelfPermission(thisActivity,
            Manifest.permission.ACCESS_FINE_LOCATION)
    != PackageManager.PERMISSION_GRANTED &&
                    ContextCompat.checkSelfPermission( getApplicationContext(), android.Manifest.permission.ACCESS_COARSE_LOCATION) != PackageManager.PERMISSION_GRANTED)) {

   // Should we show an explanation?
    if (ActivityCompat.shouldShowRequestPermissionRationale(thisActivity,
        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, we can request the permission.

      ActivityCompat.requestPermissions(thisActivity,
            new String[]{Manifest.permission.READ_CONTACTS},
            MY_PERMISSION_REQUEST_READ_FINE_LOCATION);

      // MY_PERMISSION_REQUEST_READ_FINE_LOCATION is an
      // app-defined int constant. The callback method gets the
      // result of the request.
   }
}

然后你可以在这里收到请求:

@Override
public void onRequestPermissionsResult(int requestCode,
    String permissions[], int[] grantResults) {
    switch (requestCode) {
    case MY_PERMISSION_REQUEST_READ_FINE_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 contacts-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
  }
 }

您可以在您的 Activity 中轻松调用它，但我强烈建议您阅读 documentation在这里得到一个更好的主意。

希望对您有所帮助!
