我想创建一个像Android市场第一页的布局.我正在尝试使用gridlayout,因为我想将imageview放入不同的大小和位置,我还需要输入scrollview.

其实我的问题是如何在android.support.v7.widget.GridLayout中输入scrollview？

我试过了:

<?xml version="1.0" encoding="utf-8"?>
 <ScrollView xmlns:android="http://schemas.android.com/apk/res/android"
     xmlns:app="http://schemas.android.com/apk/res/com.astuetz.viewpager.extensions.example"
     android:id="@+id/scrollView1"
     android:layout_width="wrap_content"
     android:layout_height="wrap_content" >

<android.support.v7.widget.GridLayout xmlns:android="http://schemas.android.com/apk/res/android"

    android:layout_width="match_parent"
    android:layout_height="match_parent"
    app:columnCount="10" >

    <ImageView
        android:id="@+id/ImageView1"
        android:layout_width="130dp"
        android:layout_height="130dp"
        app:layout_column="2"
        app:layout_gravity="left"
        app:layout_row="1"
        android:src="@drawable/tab_background_focused" />

    <EditText
        android:id="@+id/editText1"
        android:layout_width="wrap_content"
        android:layout_height="wrap_content"
        app:layout_column="5"
        app:layout_gravity="bottom"
        app:layout_row="1"
        android:ems="10" >

        <requestFocus />
    </EditText>

    <ImageView
        android:id="@+id/ImageView2"
        android:layout_width="130dp"
        android:layout_height="130dp"
        app:layout_column="1"
        app:layout_columnSpan="3"
        app:layout_gravity="left"
        app:layout_row="2"
        android:src="@drawable/tab_background_focused" />

    <ImageView
        android:id="@+id/ImageView3"
        android:layout_width="130dp"
        android:layout_height="130dp"
        app:layout_column="2"
        app:layout_gravity="left"
        app:layout_row="4"
        app:layout_rowSpan="2"
        android:src="@drawable/tab_background_focused" android:adjustViewBounds="true"/>

    <ImageButton
        android:id="@+id/imageButton1"
        android:layout_width="130dp"
        android:layout_height="130dp"
        app:layout_column="2"
        app:layout_gravity="left"
        app:layout_row="7"
        android:src="@drawable/background_dots" />


    <ImageView
        android:id="@+id/imageView4"
        android:layout_width="130dp"
        android:layout_height="130dp"
        app:layout_column="2"
        app:layout_gravity="left"
        app:layout_row="9" android:adjustViewBounds="true" android:src="@drawable/tab_background"/>

在Sample中PullToRefreshListInViewPagerActivity仅适用于PageAdapter.

我无法找到一种方法来使用它FragmentPageAdapter.

样品:

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

        mViewPager = (ViewPager) findViewById(R.id.vp_list);
        mViewPager.setAdapter(new ListViewPagerAdapter());
    }

    private class ListViewPagerAdapter extends PagerAdapter {

        @Override
        public View instantiateItem(ViewGroup container, int position) {
            Context context = container.getContext();

            PullToRefreshListView plv = (PullToRefreshListView) LayoutInflater.from(context).inflate(
                    R.layout.layout_listview_in_viewpager, container, false);

            ListAdapter adapter = new ArrayAdapter<String>(context, android.R.layout.simple_list_item_1,
                    Arrays.asList(STRINGS));
            plv.setAdapter(adapter);

            plv.setOnRefreshListener(PullToRefreshListInViewPagerActivity.this);

            // Now just add ListView to ViewPager and return it
            container.addView(plv, LayoutParams.MATCH_PARENT, LayoutParams.MATCH_PARENT);

            return plv;
        }

        @Override
        public void destroyItem(ViewGroup …

在iOS 7中,cachePolicy不起作用,它只是缓存下载的json.

//URLRequest
        NSString *url = [NSString stringWithFormat:@"http://www.semhora.com/jsonparser/categories/categories_%d_test.json", _categoriesIndex];
        NSURLRequest *theRequest=[NSURLRequest requestWithURL:[NSURL URLWithString:url]
                                                  cachePolicy:NSURLCacheStorageNotAllowed
                                          timeoutInterval:60.0];

如何在iOS 7中禁止缓存？

我希望我的uitextfield在输入结束时像XXX.XXX.XXX/XX.

为了限制长度我使用这个:

- (BOOL)textField:(UITextField *)textField shouldChangeCharactersInRange:(NSRange)range replacementString:(NSString *)string  {
    if (textField == _cpfField) {

        NSUInteger newLength = [textField.text length] + [string length] - range.length;
        NSCharacterSet *cs = [[NSCharacterSet characterSetWithCharactersInString:NUMBERS_ONLY] invertedSet];
        NSString *filtered = [[string componentsSeparatedByCharactersInSet:cs] componentsJoinedByString:@""];
        return (([string isEqualToString:filtered])&&(newLength <= CHARACTER_LIMIT));
    } else{
        return YES;
    }

}

问题是如何插入"." 和"/",而用户仍在编辑它.

如何使用无服务器框架处理多部分/表单数据？v.0.5.6

刚刚尝试了这个：

"requestTemplates": {
        "multipart/form-data": {
          "httpMethod": "$context.httpMethod",
          "body": "$input.json('$')",
          "queryParams": "$input.params().querystring",
          "headerParams": "$input.params().header",
          "headerParamNames": "$input.params().header.keySet()",
          "contentTypeValue": "$input.params().header.get('Content-Type')"
        },
        "application/json": {
          "httpMethod": "$context.httpMethod",
          "body": "$input.json('$')",
          "queryParams": "$input.params().querystring",
          "headerParams": "$input.params().header",
          "headerParamNames": "$input.params().header.keySet()",
          "contentTypeValue": "$input.params().header.get('Content-Type')"
        }
      }

action.js：

export function respond(event, cb) {

    var form = new formidable.IncomingForm();
    form.parse(event, function(err, fields, files) {
        if (err == null) {
            var response = {
                status: "true",
                data: fields,
                error: []
            };
            return cb(null, response);
        } else {
            console.log(err);
            return cb(null, ApiErrors.errors(402, err['message'] + fields)); …

这种奇怪的行为发生在我的构建应用程序中.

奇怪的是,这个com.nineoldandroids是一个来自android资源库的jar.

我试图删除构建源并重新编译,没有运气.

我的构建:

        maven { url 'http://download.crashlytics.com/maven' }
    }

    dependencies {
        classpath 'com.crashlytics.tools.gradle:crashlytics-gradle:1.+'
    }
}
apply plugin: 'com.android.application'
apply plugin: 'crashlytics'

repositories {
    maven { url 'http://download.crashlytics.com/maven' }
}

    compileSdkVersion 21

    }
    defaultConfig {
        applicationId "xxxxxxxx"

        versionName "1.0"
    }
    buildTypes {
        release {
            runProguard false
            proguardFiles getDefaultProguardFile('proguard-android.txt'), 'proguard-rules.pro'
        }
        debug {
            // enable crashlytics where you need
            buildConfigField "boolean", …

我想根据宽度值计算字体大小.

//Custom Font
Font.loadFont(Fonts.class.getResourceAsStream("/font/bignood/bignoodletoo.ttf"), 10)
String text = "Hello World";
Double width = 100;

对Java AWT的类似问题

类似的问题Java AWT 2

编辑:用例

想想一个有文字的按钮"PLAY MONEY"¹.现在我将文本翻译为PT_BR并立即调用"DINHEIRO FICTICIO"².如你所见,单词²大于单词¹,所以如果你设置相同,Font Size那么你会看到DINHEIRO FIC...按钮内部.

因此,每当我改变时,这里的任务就是得到它的width值Button,得到text并应用Font Size以适应全文.Buttontext

我正在向Cognito验证链接发送带有HTML标记的消息。

我正在尝试在自定义按钮内发送codeParameter：

 <div align="center" class="button-container center" style="padding-right:5px;padding-left:5px;padding-top:15px;padding-bottom:15px">
  <a href="{####}" target="_blank" style="display:block;text-decoration:none;-webkit-text-size-adjust:none;text-align:center;color:#323232;background-color:#ffc400;border-radius:25px;-webkit-border-radius:25px;-moz-border-radius:25px;max-width:210px;width:160px;width:auto;border-top:0 solid transparent;border-right:0 solid transparent;border-bottom:0 solid transparent;border-left:0 solid transparent;padding-top:5px;padding-right:25px;padding-bottom:5px;padding-left:25px;font-family:'Droid Serif',Georgia,Times,'Times New Roman',serif;mso-border-alt:none">
    <span style="font-size:16px;line-height:32px">Verify your email</span>
  </a>
</div>

但是它发送给我：
