#### 安装教程

1、在项目根目录下的build.gradle文件中
 ```gradle
allprojects {
    repositories {
        maven {
            url 'https://s01.oss.sonatype.org/content/repositories/releases/'
        }
    }
}
```
2.在entry模块的build.gradle文件中
 ```gradle
 dependencies {
    implementation 'com.gitee.chinasoft_ohos:MaterialSpinner:1.0.0'
    ......  
 }
```

在sdk6，DevEco Studio 2.2 Beta1下项目可直接运行
如无法运行，删除项目.gradle,.idea,build,gradle,build.gradle文件，
并依据自己的版本创建新项目，将新项目的对应文件复制到根目录下

#### 使用说明

组件主要由Text控件和PopupDialog形式的ListContainer组成。

原开源项目重写Text，现在openharmony项目重写DependentLayout包含Text的组合控件。

XML中添加下拉框控件:

```xml
<com.jaredrummler.materialspinner.MaterialSpinner
    ohos:id="$+id:spinner"
    ohos:width="match_parent"
    ohos:height="match_content"
    ohos:min_height="36vp"
    ohos:bottom_margin="$float:fab_margin"
    ohos:left_margin="$float:fab_margin"
    ohos:end_margin="$float:fab_margin"
    ohos:top_margin="$float:fab_margin"
    app:ms_dropdown_max_height="360vp"
    app:ms_dropdown_height="360vp"
    app:ms_background_selector_press="#FF0000"
    app:ms_background_selector_normal="#00FF00"
    app:ms_background_color="#FFFFFF"
    app:ms_text_color="$color:black"
    app:ms_hint_color="$color:black"
    app:ms_arrow_tint="#000000"
    app:ms_hide_arrow="false"
    app:ms_hint=""
    app:ms_padding_top="22"
    app:ms_padding_left="50"
    app:ms_padding_bottom="22"
    app:ms_padding_right="30"
    app:ms_popup_padding_top="0"
    app:ms_popup_padding_left="26"
    app:ms_popup_padding_bottom="0"
    app:ms_popup_padding_right="0" />
```

下拉控件加入列表项，并且在点击后触发显示:

```java
    MaterialSpinner spinner = (MaterialSpinner) findComponentById(ResourceTable.Id_spinner);
    spinner.setItems("Ice Cream Sandwich", "Jelly Bean", "KitKat", "Lollipop", "Marshmallow");
    spinner.setOnItemSelectedListener(new MaterialSpinner.OnItemSelectedListener<String>() {

@Override
        public void onItemSelected(MaterialSpinner view, int position, long id, String item) {
            DirectionalLayout toastLayout = (DirectionalLayout) LayoutScatter.getInstance(MainAbilitySlice.this)
                    .parse(ResourceTable.Layout_layout_toast, null, false);
            Text text = (Text) toastLayout.findComponentById(ResourceTable.Id_msg_toast);
            text.setText("Clicked " + item);
            text.setTextAlignment(TextAlignment.LEFT);
            text.setMultipleLine(true);
            text.setMaxTextLines(2);
            text.setTruncationMode(Text.TruncationMode.ELLIPSIS_AT_END);
            new ToastDialog(MainAbilitySlice.this)
                    .setComponent(toastLayout)
                    .setSize(DirectionalLayout.LayoutConfig.MATCH_CONTENT, DirectionalLayout.LayoutConfig.MATCH_CONTENT)
                    .setAlignment(LayoutAlignment.BOTTOM | LayoutAlignment.HORIZONTAL_CENTER)
                    .setDuration(5000)
                    .setOffset(0, 60)
                    .show();
        }
    });
```

自定义MaterialSpinner控件，可以添加自定义属性，具体可用属性如下:

| name                    | type      | info                                                   |
|-------------------------|-----------|--------------------------------------------------------|
| ms_arrow_tint           | color     | sets the color on the drop-down arrow                  |
| ms_hide_arrow           | boolean   | set to true to hide the arrow drawable                 |
| ms_background_color     | color     | set the background color for the spinner and drop-down |
| ms_background_selector  | integer   | set the background resource for the dropdown items     |
| ms_text_color           | color     | set the text color                                     |
| ms_dropdown_max_height  | dimension | set the max height of the drop-down                    |
| ms_dropdown_height      | dimension | set the height of the drop-down                        |
| ms_padding_top          | dimension | set the top padding of the drop-down                   |
| ms_padding_left         | dimension | set the left padding of the drop-down                  |
| ms_padding_bottom       | dimension | set the bottom padding of the drop-down                |
| ms_padding_right        | dimension | set the right padding of the drop-down                 |
| ms_popup_padding_top    | dimension | set the top padding of the drop-down items             |
| ms_popup_padding_left   | dimension | set the left padding of the drop-down items            |
| ms_popup_padding_bottom | dimension | set the bottom padding of the drop-down items          |
| ms_popup_padding_right  | dimension | set the right padding of the drop-down items           |
