我正在使用bitbucket,所以我可以与其他开发人员合作,但似乎我们无法让它完美地工作.从他那里取消后我得到了这个错误:

Execution failed for task ':app:processDebugResources'.

我习惯将库导入为.jar文件,但我不知道如何使用github中的项目,如下所示:https://github.com/jfeinstein10/SlidingMenu/

我想在我现有的项目中使用它.我尝试将项目文件包含在依赖项中,但它给了我一些错误

我在scrollview中有一个相对布局,我无法让它工作.我尝试将相对布局的高度设置为wrap_content,但它也不起作用.我可以使用线性布局,但我不想出于某种原因使用它.

这是我的xml:

<ScrollView xmlns:android="http://schemas.android.com/apk/res/android"
    android:layout_width="fill_parent"
    android:layout_height="fill_parent"
    android:fillViewport="true">

<RelativeLayout
    android:id="@+id/container"
    android:layout_width="fill_parent"
    android:layout_height="fill_parent"
    android:background="#FFFFFF"

    android:padding="14dp">

    <EditText

        android:id="@id/feedback_name"
        android:hint="Name"
        android:textColor="#000000"
        android:layout_alignParentTop="true"
        android:ems="10"
        android:maxHeight="48dp"
        android:textSize="14sp" />

    <EditText
        android:layout_width="match_parent"

        android:layout_below="@id/feedback_name"
        android:textSize="14sp" />

    <Spinner
        android:id="@id/feedback_concern"
        android:layout_width="match_parent"
        android:layout_height="48dp"
        android:minHeight="48dp"
        android:layout_below="@id/feedback_email" />

    <EditText
            android:layout_width="match_parent"
            android:layout_height="0dp"
            android:inputType="textMultiLine"
            android:ems="10"
            android:id="@id/feedback_message"
            android:hint="Message"
            android:textColor="#000000"
        android:layout_weight="1"
        android:minHeight="70dp"
            android:gravity="top"
            android:textSize="14sp"
            android:layout_below="@id/feedback_concern"
        android:layout_above="@id/feedback_send"
/>


    <Button
        android:layout_width="match_parent"
        android:layout_height="48dp"
        android:text="Send"
        android:maxHeight="48dp"
        android:id="@id/feedback_send"
        android:background="@color/light"
        android:textColor="#FFFFFF"
        android:layout_alignParentBottom="true"
        android:layout_alignParentLeft="true"
        android:layout_alignParentStart="true" />

    <ProgressBar
        android:layout_width="wrap_content"
        android:layout_height="wrap_content"
        android:id="@+id/progressBar"
        android:visibility="invisible"
        android:layout_gravity="center_horizontal" …

我有一个viewpager,可以保存Nostra的Universal Image Loader加载的图像.此viewpager也是listview的一部分,作为标题.将高度设置为wrap_content不起作用,它只显示任何内容,但如果我将其设置为特定的dip,则可以正常工作.我的怀疑是,viewpager在加载图像之前将其内容包装起来,因此它不会显示任何内容.

这是布局:

<?xml version="1.0" encoding="utf-8"?>

    <RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android"
    android:layout_width="fill_parent"
    android:layout_height="wrap_content" 
    android:layout_marginRight="16dp"
    android:layout_marginLeft="16dp"
    android:layout_marginTop="16dp">

    <android.support.v4.view.ViewPager
        android:layout_width="fill_parent"
        android:layout_height="wrap_content"
        android:id="@id/viewpager"
        android:layout_alignParentLeft="true"
        android:layout_alignParentStart="true" />

    <com.sblive.other.CirclePageIndicator
        android:id="@+id/titles"
        android:layout_height="wrap_content"
        android:layout_width="fill_parent"
        android:layout_marginBottom="3dp"
        android:layout_gravity="center_horizontal|bottom"
        android:layout_alignParentBottom="true"
        android:layout_alignParentLeft="true"
        android:layout_alignParentStart="true"
        android:layout_centerHorizontal="true"/>

    <ProgressBar
        android:layout_width="wrap_content"
        android:layout_height="wrap_content"
        android:id="@+id/progressBar"
        android:layout_centerVertical="true"
        android:layout_centerHorizontal="true" />

</RelativeLayout>

ViewPager的PagerAdapter的一部分:

@Override
public Object instantiateItem(ViewGroup container, int position) {

    inflater = (LayoutInflater) context
            .getSystemService(Context.LAYOUT_INFLATER_SERVICE);
    View itemView = inflater.inflate(R.layout.header_item, container,false);
    ImageView img = (ImageView) itemView.findViewById(R.id.imageView);
    ProgressBar progressBar = (ProgressBar) itemView.findViewById(R.id.progressBar);
    display(img, list.get(position), progressBar);
    ((ViewPager) container).addView(itemView);
    return itemView;
}

我按照本教程加密和解密android/java中的简单字符串:

/sf/ask/302364751/ 我做了一个Cryptography类:

public class Cryptography {

    public static SecretKey generateKey() throws NoSuchAlgorithmException {
        MessageDigest digest = MessageDigest.getInstance("SHA");
        digest.update("BhLKTyLoP YroUsRQT".getBytes());
        return new SecretKeySpec(digest.digest(), 0, 16, "AES");
    }

    public static byte[] encrypt(String message, SecretKey key) throws NoSuchAlgorithmException, BadPaddingException, IllegalBlockSizeException, NoSuchPaddingException, InvalidKeyException, UnsupportedEncodingException {
        Cipher aes = Cipher.getInstance("AES/ECB/PKCS5Padding");
        aes.init(Cipher.ENCRYPT_MODE, key);
        return aes.doFinal(message.getBytes());
    }

    public static String decrypt(byte[] cipherText, SecretKey key) throws NoSuchPaddingException, NoSuchAlgorithmException, InvalidKeyException, BadPaddingException, IllegalBlockSizeException {
        Cipher aes = Cipher.getInstance("AES/ECB/PKCS5Padding");
        aes.init(Cipher.DECRYPT_MODE, key);
        return new String(aes.doFinal(cipherText));
    }

}

我能够加密方法并给了我这个:

Encrypted username: [B@52aff408 …

这是我第一次使用Java的Pattern类,因为我想检查字符串是否为大写.特殊符号如"." 和","应被视为大写.以下是预期结果:

"test,." should return false //because it has a lowercase character
"TEST,." should return true //because all are uppercase and the special characters
"test" should return false //because it has a lowercase character
"TEST" should return true //because all are uppercase
"teST" should return false //because it has a lowercase character

我试图使用apache的StringUtils,但它不能这样工作..

我尝试在我的单例类中设置我的asynchttpclient的超时,但似乎它没有改变.我得到10000,我认为是默认值.

client.setMaxRetriesAndTimeout(0,5000);
Log.i("loopj", ""+ client.getTimeout());

编辑:

client.setTimeout(5000);

这个方法工作但是对于信息,setMaxRetriesAndTimeout怎么没有？

我尝试用scrollview包装我的relativelayout以在横向模式下使用但它不起作用.我也尝试用linearlayout包装我的相对布局,但它也不起作用.

这是xml,其中relativelayout包含在scrollview中:

<ScrollView xmlns:android="http://schemas.android.com/apk/res/android"
android:layout_width="match_parent"
android:layout_height="match_parent"
    android:fillViewport="true">
<RelativeLayout
    android:layout_width="match_parent"
    android:layout_height="match_parent"
    android:background="#2d89ef">
    <!--Some components here-->
    </RelativeLayout>
    </ScrollView>

这是我的完整xml:

<ScrollView xmlns:android="http://schemas.android.com/apk/res/android"
android:layout_width="match_parent"
android:layout_height="match_parent"
    android:fillViewport="true">
<RelativeLayout
    android:layout_width="match_parent"
    android:layout_height="match_parent"
    android:background="#2d89ef">

    <TextView
        android:id="@+id/textView"
        android:layout_width="match_parent"
        android:layout_height="wrap_content"
        android:fontFamily="Segoe UI Light"
        android:gravity="center"
        android:text="@string/app_name"
        android:textColor="#FFFFFF"
        android:textSize="25dp"
        android:textIsSelectable="false"
        android:layout_centerVertical="true"
        android:layout_alignParentLeft="true"
        android:layout_marginTop="10dp"
        android:layout_marginBottom="10dp" />

    <EditText
        android:id="@+id/editText"
        android:layout_width="275dp"
        android:layout_height="wrap_content"
        android:ems="10"
        android:fontFamily="Segoe UI Light"
        android:gravity="center_vertical"
        android:hint="@string/username"
        android:inputType="textPersonName"
        android:textColor="@android:color/white"
        android:textSize="16sp"
        android:width="200dp"
        android:layout_below="@+id/textView"
        android:layout_centerHorizontal="true">

        <requestFocus />
    </EditText>

    <EditText
        android:id="@+id/editText2"
        android:layout_width="250dp"
        android:layout_height="wrap_content"
        android:ems="10"
        android:fontFamily="Segoe UI Light"
        android:gravity="center_vertical"
        android:hint="@string/password"
        android:inputType="textPassword"
        android:textColor="@android:color/white"
        android:textSize="16sp"
        android:width="200dp"
        android:layout_below="@+id/editText"
        android:layout_alignRight="@+id/editText"
        android:layout_alignLeft="@+id/editText" /> …

我发现当我按下设备上的菜单按钮时,它会给我一个NullPointerException.

 public boolean onCreateOptionsMenu(Menu menu) {
       getMenuInflater().inflate(R.menu.main, menu); //NullPointer Here
        return true;
    }

所以我做的是通过删除上面的第二行并将返回类型更改为false来完全禁用菜单.但是,它仍然给我一个NullPointerException.这是堆栈:

我的任务是制作1-10的乘法表,但我对我的代码不满意,似乎很长:

for (int i = 1; i <= 10; i++)
    {
        System.out.println("1x" + i + " =  " + i + "\t" + "2x" + i + " =  " + (2*i)
                + "\t" + "3x" + i + " =  " + (3*i) + "\t" + "4x" + i + " =  " + (4*i)
                + "\t" + "5x" + i + " =  " + (5*i) + "\t" + "6x" + i + " =  " + (6*i) …

我正在从一个网站解析一个json并尝试从中获取一些数据.但是,它在迭代对象集合时给出了未定义的值.如果它是一个格式错误的json,不幸的是,我无法改变它.
