}

class BackGroundClass: NSObject {

    var delegate:sampleProtocal?

    func callPostService(url:String,parameters:NSDictionary){

        request.HTTPMethod = "POST"

        //Note : Add the corresponding "Content-Type" and "Accept" header. In this example I had used the application/json.
        request.addValue("application/json", forHTTPHeaderField: "Content-Type")

嗨,我是Android的新手,在我的应用程序中,我有很多图像,这ArrayList就是为什么我想借助于每3秒自动刷这些图像Timetasker,这个过程不断需要重复我们关闭应用程序.有人可以帮我一下吗

主要活动:-

public class MainActivity extends AppCompatActivity {

    ViewPager viewPager;

    Integer[] imageId = {R.drawable.image1, R.drawable.image2, R.drawable.image3, R.drawable.image4};
    String[] imagesName = {"image1","image2","image3","image4"};

    @Override
    protected void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.main_layout);

        viewPager = (ViewPager) findViewById(R.id.viewPager);
        PagerAdapter adapter = new CustomAdapter(MainActivity.this,imageId,imagesName);
        viewPager.setAdapter(adapter);
    }
}

CustomAdapter: -

public class CustomAdapter extends PagerAdapter{

    private Activity activity;
    private Integer[] imagesArray;
    private String[] namesArray;

    public CustomAdapter(Activity activity,Integer[] imagesArray,String[] namesArray){

        this.activity = activity;
        this.imagesArray = imagesArray;

我试图谈谈活动中的碎片.

在我的MainActivity中,我正在添加多个片段,所以很好.

我的主要要求是我不想添加片段已添加.

那么我们如何检查这种情况呢？

请帮帮我一些.

码:-

 private void intializingFragments(Fragment fragment) {

        FragmentManager fragmentManager = getSupportFragmentManager();

        FragmentTransaction fragmentTransaction = fragmentManager.beginTransaction();
        fragmentTransaction.add(R.id.fragment_container, fragment);
        fragmentTransaction.addToBackStack(null);
        fragmentTransaction.commit();
    }

    private View.OnClickListener intialization() {

        return new View.OnClickListener() {
            @Override
            public void onClick(View v) {

                int getId = v.getId();

                if (getId == R.id.first) {
                    intializingFragments(new Fragment1());

                } else if (getId == R.id.second) {
                    intializingFragments(new Fragment2());

                } else if (getId == R.id.third) {
                    intializingFragments(new Fragment3());

            }
        };
    }

嗨,我是非常新的Android和我的应用程序,我有更改密码页面的验证.

这意味着密码必须包含至少1个字母,1个数字和1个特殊字符的最少8个字符,为此我尝试了下面的代码,但它不起作用.

请帮我.

if(!isPasswordValidMethod(newPassword.getText().toString())){
           System.out.println("Not Valid");

                }else{

        System.out.println("Valid");
    }



     // Validate password
        private boolean isPasswordValidMethod(String password) {

            String yourString = newPassword.getText().toString();

            System.out.println("yourString is =" + yourString);

            boolean isValid = false;

            // ^[_A-Za-z0-9-\+]+(\.[_A-Za-z0-9-]+)*@[A-Za-z0-9-]+(\.[A-Za-z0-9]+)*(\.[A-Za-z]{2,})$
            // ^[\\w\\.-]+@([\\w\\-]+\\.)+[A-Z]{2,4}$

            String expression = "^(?=.*[A-Za-z])(?=.*\\\\d)(?=.*[$@$!%*#?&])[A-Za-z\\\\d$@$!%*#?&]{8,}$";
            CharSequence inputStr = password;

            Pattern pattern = Pattern.compile(expression, Pattern.CASE_INSENSITIVE);
            Matcher matcher = pattern.matcher(inputStr);
            if (matcher.matches()) {
                System.out.println("if");
                isValid = true;
            }else{
                System.out.println("else");
            }
            return isValid;
        }

当我们在dev.twitter.com/apps上创建我们的应用程序时

我们得到以下细节: -

消费者密钥(API密钥)

消费者秘密(API秘密)

那么FABRIC KEY在哪里？

在android manifesto文件中,我们必须使用这个FABRIC KEY

android宣言文件: -

<meta-data?    android:name="io.fabric.ApiKey"?    android:value="xxxxxxxxx" />

所以请帮助我.

我们怎样才能获得FABRIC KEY？

在android studio(2.2.2)中，生成签名APK后生成的proguard映射文件在哪里？

我已经生成了签名的 Apk 文件并遵循以下两个路径，但在我的根文件夹中我没有​​得到任何“mapping.txt”文件

For debug: \app\build\outputs\mapping\debug\mapping.txt

For release: \app\build\outputs\mapping\release\mapping.txt

请建议我如何获得这个“mapping.txt”文件？
