在授予所有权限时，应用程序不会移至下一个活动

Question

我正确地允许和拒绝权限，应用程序第一次运行正常，但是当授予所有权限时，下次用户启动应用程序时，它只显示启动屏幕并变得稳定，不会移动到下一个活动，而且它也不会给出任何错误，我正在尝试的是下面的。

 private static final int REQUEST_CODE_ASK_MULTIPLE_PERMISSIONS = 5;
@Override
protected void onCreate(Bundle savedInstanceState) {
    super.onCreate(savedInstanceState);
    setContentView(R.layout.activity_splash);
    splashIcon = (ImageView) findViewById(R.id.splashIcon);
    new Thread(new Runnable()
    {
        @Override
        public void run()
        {
            Animation anim1 = AnimationUtils.loadAnimation(getApplicationContext(), R.anim.bounce);
            splashIcon.setAnimation(anim1);
            anim1.setAnimationListener(new Animation.AnimationListener() {
                @Override
                public void onAnimationStart(Animation animation) {}
                @Override
                public void onAnimationEnd(Animation animation) {
                    if(Build.VERSION.SDK_INT >= Build.VERSION_CODES.M)
                    {
                        checkMultiplePermissions();
                    }else{
                        startActivity(new Intent(Splash.this,UserGuideActivity.class));
                        finish();
                    }
                }
                @Override
                public void onAnimationRepeat(Animation animation)
                {
                }
            });
        }
    }).start();
}
private void checkMultiplePermissions() {
    if (Build.VERSION.SDK_INT >= 23) {
        List<String> permissionsNeeded = new ArrayList<String>();
        List<String> permissionsList = new ArrayList<String>();
        if (!addPermission(permissionsList, android.Manifest.permission.ACCESS_FINE_LOCATION))
        {
            permissionsNeeded.add("GPS");
        }
        if (!addPermission(permissionsList, android.Manifest.permission.READ_EXTERNAL_STORAGE))
        {
            permissionsNeeded.add("Read Storage");
        }
        if(!addPermission(permissionsList, Manifest.permission.READ_SMS))
        {
            permissionsNeeded.add("Read Sms");
        }
        if(!addPermission(permissionsList, Manifest.permission.READ_CONTACTS))
        {
            permissionsNeeded.add("Read Contacts");
        }
        if(!addPermission(permissionsList, Manifest.permission.READ_CALL_LOG))
        {
            permissionsNeeded.add("Read Calllogs");
        }

        if (permissionsList.size() > 0)
        {
            requestPermissions(permissionsList.toArray(new String[permissionsList.size()]),
                    REQUEST_CODE_ASK_MULTIPLE_PERMISSIONS);
        }
    }
}



private boolean addPermission(List<String> permissionsList, String permission) {
    if (Build.VERSION.SDK_INT >= 23)

        if (checkSelfPermission(permission) != PackageManager.PERMISSION_GRANTED) {
            permissionsList.add(permission);

            // Check for Rationale Option
            if (!shouldShowRequestPermissionRationale(permission))
                return false;
        }
    return true;
}
@Override
public void onRequestPermissionsResult(int requestCode, String[] permissions, int[] grantResults) {
    switch (requestCode) {
        case REQUEST_CODE_ASK_MULTIPLE_PERMISSIONS: {

            Map<String, Integer> perms = new HashMap<String, Integer>();
            // Initial
            perms.put(android.Manifest.permission.ACCESS_FINE_LOCATION, PackageManager.PERMISSION_GRANTED);
            perms.put(android.Manifest.permission.READ_EXTERNAL_STORAGE, PackageManager.PERMISSION_GRANTED);
            perms.put(Manifest.permission.READ_SMS,PackageManager.PERMISSION_GRANTED);
            perms.put(Manifest.permission.READ_CONTACTS,PackageManager.PERMISSION_GRANTED);
            perms.put(Manifest.permission.READ_CALL_LOG,PackageManager.PERMISSION_GRANTED);

            // Fill with results
            for (int i = 0; i < permissions.length; i++)
                perms.put(permissions[i], grantResults[i]);
            if (perms.get(android.Manifest.permission.ACCESS_FINE_LOCATION) == PackageManager.PERMISSION_GRANTED
                    && perms.get(android.Manifest.permission.READ_EXTERNAL_STORAGE) == PackageManager.PERMISSION_GRANTED
                    && perms.get(Manifest.permission.READ_SMS)==PackageManager.PERMISSION_GRANTED
                    && perms.get(Manifest.permission.READ_CONTACTS)==PackageManager.PERMISSION_GRANTED
                    && perms.get(Manifest.permission.READ_CALL_LOG)==PackageManager.PERMISSION_GRANTED)
            {
                // All Permissions Granted
                startActivity(new Intent(this,UserGuideActivity.class));
                finish();
                return;
            } else {
                // Permission Denied
                if (Build.VERSION.SDK_INT >= 23) {
                    Toast.makeText(getApplicationContext(), "Please permit all the permissions", Toast.LENGTH_LONG).show();
                    finish();
                }
            }
        }
        break;
        default:
            super.onRequestPermissionsResult(requestCode, permissions, grantResults);
    }
}

Answer 1

因为如果授予所有权限，那么就false没有else必要做任何事情

    if (permissionsList.size() > 0)
    {
        requestPermissions(permissionsList.toArray(new String[permissionsList.size()]),
                REQUEST_CODE_ASK_MULTIPLE_PERMISSIONS);
    }

所以应该是这样的

    if (permissionsList.size() > 0)
    {
        requestPermissions(permissionsList.toArray(new String[permissionsList.size()]),
                REQUEST_CODE_ASK_MULTIPLE_PERMISSIONS);
    }
    else{
          startActivity(new Intent(Splash.this,UserGuideActivity.class));
                        finish();
    }

改进：您可以通过重用checkMultiplePermissions函数来消除创建映射和循环，但需要在其他地方进行相应的修改
