用户在权限屏幕上单击“允许”后启动活动

我的一项活动需要位置许可，我编写了下面的代码来获得许可。但在这种情况下，如果应用程序最初没有位置权限，则用户需要单击两次才能打开活动。我可以进行一些更改，以便一旦用户在“权限”屏幕上单击“允许”，只有然后意图才会触发。

 int PERMISSION_ALL = 1;
                            String[] PERMISSIONS = new String[0];
                            if (Build.VERSION.SDK_INT >= Build.VERSION_CODES.KITKAT) {
                                PERMISSIONS = new String[]{
                                        Manifest.permission.ACCESS_FINE_LOCATION};
                            }

                            if (!hasPermissions(getApplicationContext(), PERMISSIONS)) {
                                ActivityCompat.requestPermissions(StartupActivity.this, PERMISSIONS, PERMISSION_ALL);
                            }

                            if (hasPermissions(getApplicationContext(), PERMISSIONS)) {
                                new Thread(new Runnable() {
                                    @Override
                                    public void run() {
                                        Intent intent = new Intent(StartActivity.this, Details.class);
                                        startActivity(intent);
                                    }
                                }).start();
                            }

是的，你需要覆盖onRequestPermissionsResult

首先在onCreate

int PERMISSION_ALL = 1;
String[] PERMISSIONS = new String[0];
if (Build.VERSION.SDK_INT >= Build.VERSION_CODES.KITKAT) {
    PERMISSIONS = new String[]{
            Manifest.permission.ACCESS_FINE_LOCATION};
}

if (!hasPermissions(getApplicationContext(), PERMISSIONS)) {
    ActivityCompat.requestPermissions(StartupActivity.this, PERMISSIONS, PERMISSION_ALL);
}

然后覆盖

  @Override
    public void onRequestPermissionsResult(int requestCode, String[] permissions, int[] grantResults) {
        if (requestCode == PERMISSION_ALL) {
                Intent intent = new Intent(StartActivity.this,Details.class);
                startActivity(intent);
        }
        super.onRequestPermissionsResult(requestCode, permissions, grantResults);
    }
